    The aim of this study was to evaluate the clinical aspects of dental pulps submitted to shallow pulpotomy followed by CO2 laser radiation at five different procedures. For this purpose, initially 66 dogs' teeth were opened and about 2 or 3 mm of coronal dental pulp was removed. Continuous irrigation with saline solution was implemented. The teeth were randomly divided into 6 groups of 11 each. After cessation of bleeding, in group I, CO2 laser (Xanar-20, USA) was irradiated for 1 second at a power of 5 watts; in group II, 2 seconds at 3 watts; in Group III, 2 seconds at 5 watts; in Group IV, 1 second at 3 watts; in Group V, a continuous mode at 3 watts; Group VI served as a control, with no laser irradiation. The results showed no clinical differences between the 3 W and 5 W powers. Time period of irradiation exposition influenced definitively the clinical appearance of the dental pulps. Groups I and IV (1 second) were unable to stop the bleeding, which persisted over 15 minutes for all teeth. This may be due to the intense heat generated by CO2 laser, causing vasodilatation. Groups II and III displayed a similar appearance, but bleeding stopped in about 10 minutes. Group V (continuous mode) had no bleeding after irradiation, but a plasma-like liquid would come out for almost 2 minutes. When comparing to the control (Group VI), all the pulps would assume a jelly-like aspect, with black granulated tissue on the surface, covering totally the pulps of Group V and partially the other groups. The histological results will be discussed in a further study. From the data obtained, it seems that CO2 laser irradiation for pulpotomies should be done in a continuous mode, for clinical convenience in terms of time taken and effective irradiation.

  4. Indirect pulp therapy: an alternative to pulpotomy in primary teeth.

    Preservation of the primary teeth until their normal exfoliation is essential for normal oral function and facial growth of the child. To that end, treatment of primary teeth with large carious lesions approximating the pulp should be aimed at preserving the tooth. Currently, the pulpotomy is the most frequently used pulp treatment for cariously involved primary teeth. The purpose of this manuscript is to describe the use of an alternative to the pulpotomy, indirect pulp therapy (IPT), for the treatment of vital, primary teeth with carious involvement approaching the pulp. Accurate diagnosis of the vitality status of the pulp is critical to the success of IPT and involves careful radiographic and clinical assessment of the teeth to be sure they are healthy or at worst, reversibly inflamed. The indications for IPT are the same as for pulpotomy. The technique involves one appointment, requires that some carious dentin be left to avoid pulp exposure and requires the placement of a biologically sealing base and sealing final restoration. Teeth treated with IPT have success rates at least as good as those treated with pulpotomies, and IPT offers an acceptable alternative to pulpotomy as a treatment for vital, asymptomatic, cariously involved primary teeth.

    Full Text Available Background and Objectives: Traditionally, there are two treatment modalities for vital primary teeth with deep carious lesion, which include indirect pulp therapy (IPT and pulpotomy. Enormous research and review in vital pulp therapy gave rise to a question, if primary tooth pulpotomy is obsolete, and should IPT replace pulpotomy? IPT has shown higher long-term success rates than any pulpotomy procedures other than mineral trioxide aggregate (MTA. Hence, the objectives of this study were to evaluate the success rates of IPT using calcium hydroxide and MTA pulpotomy clinically and radiographically. Materials and Methods: Eighty primary second molars were selected and randomly divided into two therapeutic groups of 40 each. Group 1 were treated with IPT using calcium hydroxide paste and Group 2 were treated with conventional pulpotomy using MTA paste followed by stainless steel crown. Follow-up evaluation was done at an interval of 6 weeks, 3 months, and 6 months. Results: The follow-up evaluation revealed 100% clinical success in teeth treated with MTA pulpotomy and one radiographic failure of internal resorption detected at 3 months. There was 100% clinical and radiographic success with teeth treated with IPT. Though there was one radiographic failure with MTA pulpotomy, it was not statistically significant (P > 0.05. Conclusion: Indications being the same for both the procedures why not opt for IPT which offers several advantages over pulpotomy like fewer potential side effects, non-invasive, decreased chair time, child cooperation, and cost-effectiveness.

    Full Text Available Two clinical cases in which Portland cement (PC was applied as a medicament after pulpotomy of mandibular primary molars in children are presented. Pulpotomy using PC was carried out in two mandibular first molars and one mandibular second molar, which were further followed-up. At the 3, 6 and 12-month follow-up appointments, clinical and radiographic examinations of the pulpotomized teeth and their periradicular area revealed that the treatments were successful in maintaining the teeth asymptomatic and preserving pulpal vitality. Additionally, the formation of a dentin bridge immediately below the PC could be observed in the three molars treated. PC may be considered as an effective alternative for primary molar pulpotomies, at least in a short-term period. Randomized clinical trials with human teeth are required in order to determine the suitability of PC before unlimited clinical use can be recommended.

    Conventionally, few-days-old pulp exposures have been treated with root canal treatment. We report four cases of traumatized, fully matured, maxillary permanent central incisors, which have been treated by Biodentine pulpotomy several days after traumatic pulp exposure. Biodentine pulpotomy consisted of pulp tissue removal to a depth of 2 mm, then capping the pulpal wound with Biodentine, followed by immediate restoration. The teeth were assessed clinically through pulpal sensitivity tests and radiographically for periapical healing. At each recall (24 hours, 1 week, 30 days, 3, 6, 12, and 18 months), no spontaneous pain was observed; the pulp showed signs of vitality and absence of periapical radiolucency after 18 months. Biodentine pulpotomy is recommended as a treatment option for cases of vital pulp exposure in permanent incisors due to trauma.

    2015-06-01

    The aim of this paper was to review the history and the scientific literature published on pulpotomy medicaments and to present the findings of these studies. The review showed that pulpotomy of primary teeth has been treated with many different techniques and medicaments, that some of these approaches are controversial and that their results have presented variables of success rates in term of clinical, radiographic and histologic observation. It is important that all clinicians, particularly for pediatric dentists, be up to date with the recent trends in this area of dental treatment for children.

    The histological success of mineral trioxide aggregate (MTA) pulpotomy for treatment of irreversible pulpitis in human teeth as an alternative treatment was investigated in this study. Fourteen molars which had to be extracted were selected from patients 16-28 years old. The selection criteria include carious pulp exposure with a history of lingering pain. After isolation, caries removal and pulp exposure, MTA was used in pulpotomy treatment. Patients were evaluated for pain after 24 h. Two patients were lost from this study. Twelve teeth were extracted after 2 months and were assessed histologically. Recall examinations confirmed that none of the patients experienced pain after pulpotomy. Histological observation revealed that all samples had dentin bridge formation completely and that the pulps were vital and free of inflammation. Although the results favour the use of MTA as a pulpotomy material, more studies with larger samples and a longer recall period are suggested to justify the use of MTA for treatment of irreversible pulpitis in human permanent teeth.

    The material comprised 37 young posterior teeth with deep carious lesions and exposed pulps, treated with partial pulpotomy and dressed with calcium hydroxide. The teeth were divided into two groups. Group 1 consisted of 31 teeth with no clinical or radiographic symptoms before treatment, Group 2 of 6 teeth with temporary pain, widened periodontal space periapically and/or productive osteitis, i.e. increased density of the surrounding alveolar bone. After an observation time of 24 to 140 months (mean = 56 months), healing had occurred in 29 of 31 teeth in Group 1 (93.5%) and in 4 of 6 teeth in Group 2. It was concluded that the present, as well as previously reported results indicate that partial pulpotomy may be an adequate treatment for young permanent molars with a carious exposure, although more studies are needed before the treatment can be recommended for routine clinical use.

    2016-01-01

    Irreversible pulpitis is the most common reason for endodontic treatment in primary and permanent teeth. Root canal therapy and extraction are the two viable and most documented treatment options for the same. Studies with regards to management of mature permanent teeth with carious exposure and treatment with vital pulp therapies such as adult permanent tooth pulpotomy are scarce. However, permanent tooth pulpotomy with the new calcium-silicate based cements (Mineral Trioxide Aggregate and Biodentine) can help preserve the tooth pulp vitality and promote healing and repair foregoing the more invasive root canal therapy procedure. A 12-year old male patient with irreversible pulpitis in right mandibular first permanent molar was treated with complete coronal pulpotomy with placement of Biodentine in the pulp chamber and a full coronal coverage using stainless steel crown. Clinical and radiographic examinations were performed at three, six, twelve and eighteen months. At the end of 18 months, the patient was completely asymptomatic and the tooth was free of any clinical and radiographic signs of inflammation and infection. PMID:27630966

    Full Text Available Abstract Background In Tanzania, oral health services are mostly in the form of dental extractions aimed at alleviating acute dental pain. Conservative methods of alleviating acute dental pain are virtually non-existent. Therefore, it was the aim of this study to determine treatment success of emergency pulpotomy in relieving acute dental pain. Methods Setting: School of Dentistry, Muhimbili National Hospital, Dar es Salaam, Tanzania. Study design: Longitudinal study. Participants: 180 patients who presented with dental pain due to acute irreversible pulpitis during the study period between July and August 2001. Treatment and evaluation: Patients were treated by emergency pulpotomy on permanent posterior teeth and were evaluated for pain after one, three and six week's post-treatment. Pain, if present, was categorised as either mild or acute. Results Of the patients with treated premolars, 25 (13.9% patients did not experience pain at all while 19 (10.6% experienced mild pain. None of the patients with treated premolars experienced acute pain. Among 136 patients with treated molars 56 (31% did not experience any pain, 76 (42.2% experienced mild pain and the other 4 (2.2% suffered acute pain. Conclusion The short term treatment success of emergency pulpotomy was high being 100% for premolars and 97.1% for molars, suggesting that it can be recommended as a measure to alleviate acute dental pain while other conservative treatment options are being considered.

    Formocresol is widely used in primary teeth pulpotomies; however it is known to have several side effects. The purpose of this study was to assess pulpal changes of primary teeth pulps after pulpotomy with sodium hypochlorite and formocresol. In this randomized clinical trial, 22 teeth were selected. These teeth were randomly divided into 2 groups (formocresol; n=11 and sodium hypochlorite n=11). Two months post-operatively teeth were extracted and pulpal responses were evaluated by recording the degree of inflammation and extent of pulpal involvement. Dentinal bridge formation was also evaluated. Finally the data was analyzed with McNemartest. The formocresol group demonstrated mild inflammation in 4 cases whereas sodium hypochlorite had mild inflammation in six cases. Severe inflammation was only found in 1 case in the sodium hypochlorite group, but it was present in 4 cases in the formocresol group. In sodium hypochlorite group there were no cases of necrosis, and dentinal bridge was found in 3 cases, unlike, the formocresol group which had necrosis but no dentinal bridge formation. Based on the results of this study sodium hypochlorite may be a suitable solution for conducting pulpotomy in primary teeth.

    This investigation evaluated the success of a formocresol pulpotomy technique in which hemostasis was obtained with the same formocresol dampened cotton pellet used to medicate the root pulp stumps and to compare the findings of this investigation with data of published formocresol pulpotomy studies in which hemorrhage was controlled by traditional means. Clinical and radiographic data were available for 194 primary molars in 112 patients with follow up times ranging from 5 to 109 months (mean = 38 months). Overall radiographic success was 87%. The most frequently observed pulpal responses were calcific metamorphosis (34%) and internal resorption (10%). Overall clinical success was 98%. Only 7 of 194 molars were extracted due to radiographic and/or clinical failure. Overall cumulative probability of survival remained high over time with a cumulative survival rate of over 94% over 4 years. The success rates for this variation of the formocresol technique are comparable to those success rates in the literature where hemostasis was obtained in a separate step using a nonmedicated cotton pellet. The results of this study suggest that using the same cotton pellet dampened with full strength formocresol to obtain hemorrhage control and medicate the root pulp is an acceptable variation of the traditional formocresol pulpotomy technique.

  5. Indirect pulp capping and primary teeth: is the primary tooth pulpotomy out of date?

    2008-07-01

    Formocresol pulpotomy (FP) in the United States is most frequently used to treat asymptomatic caries near the pulp in primary teeth. Indirect pulp therapy (IPT) is also indicated and has a significantly higher long-term success. Pulpotomy is thought to be indicated for primary teeth with carious pulp exposures, but research shows the majority of such teeth are nonvital or questionable for treatment with vital pulp therapy. IPT has a significantly higher success in treating all primary first molars, but especially those with reversible pulpitis compared with FP. The purpose of this article was to review the dental literature and new research in vital pulp therapy to determine the following: (1) Is a pulpotomy indicated for a true carious pulp exposure? (2) Is there a diagnostic method to reliably identify teeth that are candidates for vital pulp therapy? (3) Is primary tooth pulpotomy out of date, and should indirect pulp therapy replace pulpotomy?

    The aim of the present study was to clinically and radiographically evaluate Mineral Trioxide Aggregate (MTA) as an agent for pulpotomy in primary teeth and to compare it with that of formocresol (FC) pulpotomy. Nineteen children between the ages of 6 to 8 years with 40 carious primary molars were treated with pulpotomy using either FC or MTA. All the molars were evaluated clinically and radiographically at regular intervals over a twenty four month period. The observations were tabulated and statistically analyzed. Eighty five percent success was observed with FC pulpotomy whereas MTA showed 95% success. MTA showed a higher clinical and radiographic success rate than FC. MTA may be a favorable material for pulpotomy in primary teeth whose pulps have been compromised by a carious or mechanical pulp exposure.

    The purpose of this study was to compare pulpal and periapical tissue reactions to electrosurgery versus formocresol pulpotomy techniques in the primary teeth of dogs. The study was conducted on 33 primary teeth of three mongrel dogs between the ages of one to three months. Each dog had three teeth treated by Formocresol Pulpotomy with Mechanical Coronal Pulp Removal (FC), three teeth treated by Electrosurgery Pulpotomy with Mechanical Coronal Pulp Removal (ES/MCPR), three teeth treated by Electrosurgery Pulpotomy with Electrosurgical Coronal Pulp Removal (ES/ECPR), and two teeth serving as untreated Controls. Dogs one, two and three were sacrificed performing the pulpotomies at two, four and six weeks, respectively. The pulp, periapical tissue and after surrounding bone were submitted to histological examination and the histological reaction was recorded. The results were fourteen out of 18 unfavorable and zero out of three favorable histological reactions occurred in the FC treated teeth. Six out of 18 unfavorable and one out of three favorable histological reactions occurred in the ES/MCPR treated teeth. Nine out of 18 unfavorable and two out of three favorable histological reactions occurred in the ES/ECPR treated teeth. One out of 18 unfavorable and zero out of three favorable histological reactions occurred in the untreated Control teeth. The conclusion of this study is that of the three experimental groups, the teeth treated by Electrosurgery Pulpotomy with either Mechanical or Electrosurgical Coronal Pulp Removal exhibited less histopathological reaction than the teeth treated by Formocresol Pulpotomy.

    Vital pulpotomy is a single-stage procedure defined as the surgical amputation of the coronal portion of exposed vital pulp, usually as a means of preserving the vitality and function of the remaining radicular portion. The aim of this study was to compare the clinical and radiographic success rates for electrosurgical vs formocresol pulpotomy in human primary molar teeth. This was a prospective, randomized clinical trial. In this randomized clinical trial, pulpotomies were performed on 70 primary molars in children aged 5-10 years. The teeth were treated using either a conventional formocresol (35 teeth) or electrosurgical technique (35 teeth). Following the pulpotomy procedure, the teeth were evaluated for clinical and radiographic success for three, six and nine months. The teeth were evaluated for the presence of pain, abscess, fistula, mobility, internal and external resorption, and radiolucency. The data were assessed with Fishers' Exact test. After nine months of follow-up, the clinical and radiographic success rates were 96 and 84% respectively in the electrosurgical group and 100 and 96.8% respectively in the formocresol group. There was no statistically significant difference between the success rates in the two groups ( P > 0.05). Our results showed the failure rates for electrosurgical pulpotomy to be equal to those for formocresol pulpotomy. Although electrosurgical pulpotomy is a nonpharmacological technique giving favorable results, it is still a preservative technique. Further studies using larger samples and longer evaluation periods are recommended.

    Full Text Available One of the major problems facing the dentist who treat children, especially the primary dentition, is the maintenance of a health dental pulp which has been advocated for use in the treatment of the involved pulp. One treatment that has received wide acceptance clinically, chemically and histologically, for the purpose of maintaining a healthy radicular pulp, is the application of formocresol for pulpotomy in primary teeth. A pulpotomy or vital amputation, on primary teeth is the procedure of removing the coronal part of the pulp tissue, and a medicament is applied on the orifice of the remaining tooth tissue, as a result of deep caries, and the maintenance of vital pulp tissue. The most widely accepted medicards for pulpotomy in primary teeth is formoresol, but as a 1/5 dilution of the original Buckley's formula. Although the pulpotomy treatment has its limitation, the use of formocresol is the medicament of choice. The difficulties in diagnosing primary teeth as vital and health through clinical and radiographic findings needs a thorough examination but accurate and precised. The intention of this paper is to help in understanding the importance of pulpotomy treatment on primary teeth, the right indication, formocresol mechanical response, and step by step procedures of the pulpotomy treatment. We hope that it can broaden our mind and knowledge to the importance of pulpotomy treatment on primary teeth with on-fifth diluted formocresol (20%.

    This report describes three cases of complicated crown fractures treated with partial pulpotomy using BioAggregate. Three maxillary permanent central incisors with complicated crown fracture were treated by partial pulpotomy using BioAggregate and reviewed clinically and radiographically for 24 months. Throughout this period, there was no spontaneous pain, periapical radiolucency, and coronal discoloration; the pulp was observed to be vital. Based on these findings, it was concluded that BioAggregate can be used in partial pulpotomy treatment of complicated crown fracture.

    Studies show that human permanent teeth with carious pulpal exposures can result in a high clinical success rate when treated with pulpotomy and direct pulp capping with mineral trioxide aggregate (MTA pulpotomy). In this case report, a 19-year-old female patient with a second premolar with irreversible pulpitis and symptomatic apical periodontitis was treated with MTA pulpotomy. Follow-up electric pulp tests showed viability of the tooth at three and 10 months. Ten months after the initial treatment, the tooth was extracted for orthodontic reasons and processed for histological examination. Microscopically, the pulpal wound treated with MTA was free from inflammation and covered with a thin layer of reparative dentin. The authors conclude that, when caries and bacterial contamination can be removed from the dentin-pulp complex, the inflamed but vital pulp of a permanent tooth may have a chance to return to a healthy, functional status after MTA pulpotomy.

    Diluted formocresol is the most widely recommended primary tooth pulpotomy medicament, but it is not commercially available. This investigation surveyed practicing pediatric dentists about the concentration of formocresol that they use to perform pulpotomies and, if they use diluted formocresol, where they obtain it. Eight-hundred-and-six surveys were sent to a randomly selected sample of practicing pediatric dentists, and 422 were returned for a 52% response rate. Eighty-four percent of the respondents use formocresol for their primary tooth pulpotomies. Of those, 69% use full strength, 27% use diluted and 4% don't know. Sources of diluted formocresol for those who use the diluted form include: 34% who buy it that way, 58% who dilute it themselves and 8% who have the pharmacy dilute it. The majority of pediatric dentists who use formocresol for primary tooth pulpotomies use a full strength formulation.

    The purpose of this prospective study was to compare light-cured calcium hydroxide (Ca(OH)2) with diluted formocresol (FC) for its success as a primary molar pulpotomy medicament Selection criteria included at least 2 matching, asymptomatic, contralateral primary molars requiring vital pulpotomies. Matched teeth in each patient were randomized to receive either Ca(OH)2 or FC as a pulpotomy medicament. All teeth were restored with prefabricated metal crowns. Twenty patients (34 pairs of teeth) were followed clinically and radiographically for > or =1 year. Two blinded, standardized, and calibrated examiners evaluated and scored each radiograph for signs of pathology, based upon a modified scale previously proposed. Findings were grouped in: (a) 0 - 6; (b) 7 - 12; and (c) 13 - 24 month intervals. Radiographic scoring favored the FC group of the 7- to 12- and 13- to 24-month intervals (Pformocresol as a pulpotomy agent.

    Pulpotomy of primary incisors is a serious challenge due to the lack of a distinct boundary between the coronal and the radicular pulp and the inaccuracy of the clinical indication criteria. The aim of the present study is the clinical and radiographic evaluation of pulpotomy versus root canal therapy (RCT) of vital primary incisors. A total of 100 incisors in 50 patients (female: 27, male: 23) aged 3-4 years were allocated to formocresol pulpotomy (45 teeth) and RCT (46 teeth) using zinc oxide-eugenol. The radiographic and clinical evaluation of treatment outcomes was performed at 12 and 24 months post-operatively. A history of spontaneous pain, missing restorations, recurrent caries, mobility and percussion sensitivity, parulis or fistula, erythema, and swelling were recorded. Data analysis was performed based on two sample proportional test. The clinical success rate was 86.9% for pulpotomy and 95.6% for RCT (P > 0.05). The radiographic assessment exhibited no pathologic signs in 76.08% of pulpotomy group and 91.3% of RCT group and the difference was statistically significant (P < 0.05). The most common pathologic finding was periodontal widening followed by external/internal root resorption. Periapical radiolucency and fistula in pulpotomized teeth was significantly higher than in RCT-treated teeth (P < 0.05) It may be concluded that the root canal therapy of vital primary incisors may be efficiently substituted for the pulpotomy of these teeth.

    Full Text Available Background and Aim: Pulpotomy is one of the routine methods for pulp therapy of primary teeth. At present it is a fact that ideal agent for this has not been discovered. The aim of this study was to compare the clinical and radiographic success rates of electrosurgical pulpotomy versus formocresol pulpotomy in human primary molar teeth. Materials and Methods: In this clinical trial study, pulpotomy was performed on 68 primary molars in children aged from 5 to 10 years. The teeth were treated using either a conventional formocresol (35 teeth, or electrosurgical technique (33 teeth. Following the pulpotomy procedure, the teeth were evaluated regarding clinical and radiographic success for 3, 6 and 9 months periods. The teeth were evaluated clinically and radiographically for the presence of pain, abscess, fistula, mobility, internal and external resorption and radiolucency. Finally clinical and radiographic data were collected and analyzed with Fisher exact test using P0/05. Conclusion: Although electrosurgical pulpotomy is a nonpharmacological and easy to use technique, further investigations with longer evaluation periods are suggested.

    Considering formocresol's toxicity, Ca(OH)(2) partial pulpotomy (PP) was studied as a treatment alternative. To compare success rates of Ca(OH)(2) PP versus formocresol pulpotomy (FP) treatment of pulpally exposed lower primary molars. A total of 84 lower primary molars, which met study criteria, from 56 child patients were randomly assigned for each treatment. After treatment, blinded clinical and radiographic evaluation with 96.9% and 90% reliability was performed at 6-month intervals to determine treatment success/failure. Chi-squared test was used to compare success rates between the two treatments. The success rates from 6 to 36 months for PP ranged from 95.03% to 75%, whereas for FP, it was 92.7-74.2%. The success rates for the two treatments at each 6-month interval were not different (P ≥ 0.05). The most frequent failure was internal resorption, affecting five FP teeth and three PP teeth. The resorption was arrested in five of the teeth and was replaced by a radiopaque calcified tissue in one case. Considering the favourable clinical and radiographic success rate of PP and the potentially toxic effects of formocresol leads us to recommend the use of PP instead of FP in primary teeth with deep carious lesions. © 2011 The Authors.

    Full Text Available Background: Vital pulpotomy is a single-stage procedure defined as the surgical amputation of the coronal portion of exposed vital pulp, usually as a means of preserving the vitality and function of the remaining radicular portion. Objectives : The aim of this study was to compare the clinical and radiographic success rates for electrosurgical vs formocresol pulpotomy in human primary molar teeth. Settings and Design: This was a prospective, randomized clinical trial. Materials and Methods: In this randomized clinical trial, pulpotomies were performed on 70 primary molars in children aged 5-10 years. The teeth were treated using either a conventional formocresol (35 teeth or electrosurgical technique (35 teeth. Following the pulpotomy procedure, the teeth were evaluated for clinical and radiographic success for three, six and nine months. The teeth were evaluated for the presence of pain, abscess, fistula, mobility, internal and external resorption, and radiolucency. Statistical Analysis : The data were assessed with Fishers′ Exact test. Results: After nine months of follow-up, the clinical and radiographic success rates were 96 and 84% respectively in the electrosurgical group and 100 and 96.8% respectively in the formocresol group. There was no statistically significant difference between the success rates in the two groups ( P > 0.05. Conclusions: Our results showed the failure rates for electrosurgical pulpotomy to be equal to those for formocresol pulpotomy. Although electrosurgical pulpotomy is a nonpharmacological technique giving favorable results, it is still a preservative technique. Further studies using larger samples and longer evaluation periods are recommended.

    To compare the outcome after 6 months of the application of formocresol (FC) or mineral trioxide aggregate (MTA) during pulpotomy in primary molar teeth. A maximum of 126 children (aged 5-9 years) with carious primary teeth that required pulpotomy were selected. Following randomization, a standard pulpotomy preparation was undertaken, and the coronal pulp removed and bleeding arrested. In the FC group, cotton balls, soaked in FC, were placed for 5 min, and then the pulp chamber was filled with Zonalin, a pulpotomy agent. In the MTA group, a 1-mm-thick paste of MTA was used as a pulpotomy agent. The crowns in both groups were restored with amalgam or glass ionomer. The teeth of 100 patients were evaluated and compared clinically and radiographically after 3 and 6 months. No signs of clinical failure were observed at the 3- and 6-month follow-up appointments in either group. There were no significant differences in the radiographic findings of the teeth and surrounding tissue at the 3-month follow-up. However, at the 6-month follow-up, significantly more cases (P = 0.036) with root resorption were seen in the FC group; no cases of resorption occurred amongst the MTA cases. The surrounding tissue showed radiographic signs of post-treatment disease in four FC cases; none was seen in the MTA cases. After 6 months, pulpotomy with MTA was associated with fewer cases of root resorption and post-treatment disease. MTA appears to be a reliable alternative material for pulpotomy in primary molar teeth.

    The aim of this study was to evaluate and compare the clinical applicability of various MTA materials as partial pulpotomy materials in permanent teeth. Partial pulpotomy was performed on 104 permanent teeth from 82 people (mean 29.3±14.8years old), who met the inclusion criteria in randomized clinical trial. The teeth were divided into three groups: ProRoot MTA (n=33), OrthoMTA (n=36), RetroMTA (n=35). Clinical examination and radiographic comparison were carried out at 1, 3, 6 and 12 months after the treatment. Survival analysis was performed using the Kaplan-Meier survival curves and log rank tests. Partial pulpotomy sustained a high success rate up to 1year with no significant differences in the outcomes treated with three MTA materials: ProRoot MTA, 96.0%; OrthoMTA, 92.8%; RetroMTA, 96.0%. The Kaplan-Meier survival function curves showed no significant differences among three groups concerning clinical and radiographic cumulative survival rates. In addition, no potential prognostic factors related to the success rate of partial pulpotomy among age, sex, tooth type, root apex status, the site and type of pulp exposure, and the type of restoration were observed in log rank analysis. Partial pulpotomy with ProRoot MTA, OrthoMTA and RetroMTA had favorable results and clinical and radiographic results were not significantly different in three groups after 1year.

    The purpose of this study was to compare the effects of Nd:YAG laser pulpotomy to formocresol pulpotomy on human primary teeth. Patients with a primary tooth that required pulpotomy because of pulpal exposure to caries, were selected for this study. After removal of coronal pulpal tissue, Nd:YAG laser at 2 W, 20 Hz, 100 mJ or a 1:5 dilution of formocresol was introduced into the canal orifice for complete hemostasis. IRM paste was then placed over the pulp stump, and the tooth was restored either with composite resin or stainless steel crown. Sixty-eight teeth were treated with Nd:YAG laser and followed up for 6 to 64 months. Clinical success was achieved in 66 out of the 68 teeth (97 %), and 94.1 % were radiographically successful. In the control group, 69 primary molars were treated with formocresol and followed up for 9 to 66 months; 85.5 and 78.3% achieved clinical and radiographic success, respectively. The success rate of Nd:YAG laser pulpotomy was significantly higher than that of formocresol pulpotomy. The permanent successors of the laser-treated teeth erupted without any complications.

    Introduction Inspite of latest advances in the materials and techniques practiced for the treatment of pulpally infected teeth with better reported success rate, still the question arises for safety and effectiveness of these medicaments. Aim The objective of the present study was to compare the effectiveness of the Low Level Laser Therapy to Mineral Trioxide Aggregate (MTA) when used for pulpotomy in vital human primary molars. Materials and Methods The sample consisted of 40 primary molars from 29 children aged four to seven years. The teeth were selected based on clinical, radiographic criteria and randomly allocated to two groups. All the 40 primary molars were subjected to standard pulpotomy procedure, where in 20 molars received MTA (Group I) and 20 molars received LLLT (Group II) pulpotomy. Children were recalled at 3, 6 and 12 months intervals and pulpotomised molars were examined clinically and radiographically. Data was analysed using chi-square test. Results MTA showed 94.7% success rate at all the three intervals, where as LLLT showed a success of 95% at three months, which decreased gradually to 85% at six months and 80% at 12 months. Intergroup comparisons were not significant. Conclusion Low level laser therapy can be considered for primary teeth pulpotomy and its success is comparable to MTA pulpotomy technique. PMID:26894180

    The aim of this study was to evaluate the scientific evidence of pulpotomy in primary teeth comparing mineral troxide aggregate (MTA), calcium hydroxide, ferric sulphate, and electrosurgery with formocresol. A systematic search using key words was conducted using seven databases up to December 10, 2013. Clinical articles in English, Portuguese and Spanish were selected, which were in accordance with the inclusion and exclusion criteria and the research objective of comparing whether pulpotomy performed with formocresol in primary teeth is more effective than other medicaments or techniques. Out of the 12,515 publication initially identified, 30 clinical articles were included in the systematic review and analysed by four meta-analyses. The success rate of MTA (94.6 %) was higher than that of formocresol (87.4 %), with a statistically significant difference (OR = 0.39; 95 % CI = 0.25-0.62). Formocresol pulpotomy success was not statistically different from ferric sulphate or electrosurgery. MTA was clinically and radiographically superior to formocresol for pulpotomy of primary teeth. The other alternatives to formocresol such as electrosurgery and ferric sulphate can be used instead of formocresol since they showed success similar to formocresol. In addition, there is no evidence to support calcium hydroxide for pulpotomies in primary teeth.

    The study evaluated the effects of 3 percent sodium hypochlorite (NaOCl) and formocresol (FC) as pulp dressing agents in pulpotomized primary molars. One hundred children between three and six years each with at least one primary mandibular second molar requiring pulpotomy were randomly allocated to two groups (of 50 each). All the teeth received stainless steel crown after conventional pulpotomy procedure with either NaOCI (applied for 15 second) or FC (applied for one minute). Clinical and radiographic signs/symptoms were blindly recorded at zero, six. and 12 months. The differences were statistically analyzed using the Fisher's exact test. At six months, 100 percent clinical success was found with both NaOCl, and FC. Radiographic success rates for NaOCl were 98 percent and 92 percent at 6- and 12-month recalls respectively. FC group showed 94 percent and 93 percent radiographic success rates at the same periods respectively. There was no statistically significant difference between the groups. NaOCl can be suggested as a pulpotomy agent for primary teeth pulpotomies. However further clinical studies with long-term follow-ups are needed to test the efficacy of NaOCl as a pulpotomy medicament in primary teeth.

    To evaluate and compare mineral trioxide aggregate (MTA) and formocresol as pulpotomy medicaments by clinical and radiographic assessments and to assess the histological features of both pulpotomy medicaments in deciduous teeth. This study was performed on 100 mandibular deciduous molar teeth requiring pulpotomy treatment. Children between age four and six years were randomly selected and divided into formocresol or MTA group. The patients were recalled after 3, 6, 9, 12 months respectively and evaluated clinically and radiographically. Histological assessment was done on lower deciduous canine teeth, which were undergoing serial extraction for interceptive orthodontic purpose. Pulpotomy was done on four teeth with formocresol and another four teeth with MTA. The teeth were extracted after six months following pulpotomy procedure and histologically evaluated. Two freshly extracted carious teeth were taken as controls. Clinical and radiographic criteria were laid and Chi analysis revealed significant difference in mobility ( P≤0.05), periodontal ligament widening ( P≤0.01 level) and inter - radicular radiolucency ( P≤0.02 level) between two groups at the end of 12 months. Histologically, in MTA group, a layer of new dentine formation with less dentinal tubules at the pulpotomized site was found. In formocresol group, increased inflammatory cells, a zone of atrophy, were noted in radicular portion of pulp. MTA is superior to formocresol clinically, radiographically. Histological analysis showed better reparative ability with hard tissue barrier formation with MTA compared to formocresol.

    To assess and compare the clinical and radiographic success rates of biodentine and formocresol for pulpotomy in human primary teeth. A randomized, split-mouth, double-blind, controlled clinical trial was carried out in 37 healthy 4- to 8-year-old children with 56 pairs (112 teeth) of contralateral primary molars indicated for pulpotomy. Matched teeth in each pair were randomized to undergo either biodentine (n = 56 teeth) or formocresol (n = 56 teeth) pulpotomy. In both groups, the teeth were restored with stainless steel crowns. The teeth were evaluated clinically and radiographically at 3 and 6 months by two blinded, standardized, and calibrated examiners. The data were analyzed using chi-square and McNemar tests with a P value of formocresol (100%), without any statistically significant difference (P = 1). Pulp canal obliteration was radiographically observed in 10/56 (17.9%) and 7/56 (12.5%) cases in the biodentine and formocresol groups, respectively. Both pulpotomy techniques showed favorable clinical and radiographic outcomes at 3 and 6 months posttreatment without any significant difference. Hence, biodentine has the potential to become a substitute for formocresol in primary molar pulpotomies.

    Full Text Available The aim of the present study was to evaluate histologically the pulp response of anionic lyophilized collagen matrix with or without hydroxyapatite as a biomaterial pulp-capping agent in pulpotomy of dogs' teeth. Sixty pre-molar roots from three dogs were used. After pulpotomy, the remaining pulp tissue was capped with one of the following materials: Group I (20 roots: anionic lyophilized collagen matrix; Group II (20 roots: anionic lyophilized collagen matrix associated with hydroxyapatite; Group III (10 roots: calcium hydroxide (p.a. paste in saline; Group IV (10 roots: zinc oxide eugenol cement. After 90 days the animals were killed by anesthetic overdose and the teeth were removed and submitted to histological processing. According to the histopathological results, we concluded that the zinc oxide eugenol cement and anionic lyophilized collagen matrix with or without hydroxyapatite did not present satisfactory pulp response and that calcium hydroxide is the suitable material for pulpotomy.

However, the problem on root canal treatment on deciduous molars, especially with children who is noncooperative because the difficulty to get access to the root canal on children and root canals on deciduous molars are very complex. Mortal pulpotomy is the way to eliminate necrotic pulp tissue in pulp chamber and replace it with material filling. The material is a combination between formocresol and zinc oxide eugenol. The result on formocresol pulpotomy on deciduous teeth can be seen in clinical, radiographic and histological examination of the teeth, abutment tissue and the growth permanent teeth germ. On this patient the mortal pulpotomy treatment had been done with formocresol on one visit. After a month, on the clinical evaluation there are no subjective complaints and no signs of gingival inflammation.

    Full Text Available Background and Aim: Vital pulpotomy in primary teeth is performed to maintain the vitality of the pulp and tooth until normal exfoliation. Different materials such as zinc oxide- eugenol, calcium hydroxide and formocresol are used in this procedure. The aim of this study was to evaluate the application of formocresol (FC and mineral trioxide aggregate (MTA in pulpotomy of primary molars. Materials and Methods: In this clinical trial, one hundred and twenty six children (aged 5 to 9 years old with dental caries that were candidate for pulpotomy were selected and randomly divided into two groups. After removing the roof of the pulp chamber, coronal pulp was cut at the orifices and bleeding controlled. In control group, formocresol was applied for 5 minutes. In case group, MTA paste was used as pulpotomy agent. The crowns of both groups were restored with amalgam and the teeth were evaluated clinically and radiographically after 3 and 6 months follow up. Data were analyzed by Fisher test with p<0.05 as the limit of significance. Results: No sign of clinical failure was observed after 3 and 6 months follow-up. Comparison between the two methods revealed no significant difference in radiographic findings of the teeth and surrounding tissues after 3 months follow-up. However, after 6 months follow-up, internal resorption was observed radiographically in four cases of formocresol group. Conclusion: Based on the results of this study, pulpotomy with MTA showed more successful results than formocresol radiographically. MTA is recommended as a good substitute for formocresol in pulpotomy of primary molars.

    Full Text Available This case report describes the partial pulpotomy treatment of complicated crown fractures of two cases by using white mineral trioxide aggregate (WMTA with long-term follow-up. In the cases presented here, to injured incisor teeth were open apices and the pulp exposure site was large, so it was decided to perform vital pulpotomy with WMTA. Long-term follow-up examinations revealed that the treatment preserved pulpal vitality with continued root development and apex formation. WMTA may be considered as an alternative option for the treatment of traumatized immature permanent teeth.

    Full Text Available Congenital heart disease is a condition of heart anomaly found since birth. The most common is ventricular septal defect whereby an aperture is found in the partition of heart chamber. It is estimated that 40,000 newborn in Indonesia have this defective condition. Dental treatment for patients with such condition must be undertaken in a very cautious way. Tooth with multiple caries can potentially lead to endocarditis bacteria. As such, dentist must be watchful on dental treatment that may worsen the patient’s condition. To prevent endocarditis bacteria, a prophylaxis antibiotic is required as recommended by the American Heart Association (AHA. In this particular case, a dental treatment was undertaken to a child patient with congenital heart disease. Previously, the patient has undergone dental treatment in the form of multiple extractions under general anesthesia before conducting cardiac surgery. In this case the treatment includes mortal pulpotomy, GIC restoration, and fissure sealant – all conducted in one visit under general anesthesia. A year after the treatment, there are no complaints from the patient and no irregularity on x-ray results.

    The study evaluated the effects of formocresol (FC), ferric sulphate (FS), calcium hydroxide (Ca[OH](2)), and mineral trioxide aggregate (MTA) as pulp dressing agents in pulpotomized primary molars. Sixteen children each with at least four primary molars requiring pulpotomy were selected. Eighty selected teeth were divided into four groups and treated with one of the pulpotomy agent. The children were recalled for clinical and radiographic examination every 6 months during 2 years of follow-up. Eleven children with 56 teeth arrived for clinical and radiographic follow-up evaluation at 24 months. The follow-up evaluations revealed that the success rate was 76.9% for FC, 73.3% for FS, 46.1% for Ca(OH)(2), and 66.6% for MTA. In conclusion, Ca(OH)(2)is less appropriate for primary teeth pulpotomies than the other pulpotomy agents. FC and FS appeared to be superior to the other agents. However, there was no statistically significant difference between the groups.

    In cariously exposed immature permanent teeth, the treatment choice is controversial in pediatric dentistry. Radical root canal treatment usually appears to be the solution for these teeth. Even partial pulpotomy is a vital treatment for traumatically exposed immature permanent teeth; extending the borders of indication towards cariously exposed immature permanent teeth with reversible pulpitis may abolish the necessity of pulpectomy. This article describes the partial pulpotomy of a cariously affected immature permanent teeth and the follow-up for 1 year. A healthy 11-year-old male patient was referred to Gazi University Faculty of Dentistry Department of Pediatric Dentistry. The patient had reversible pulpitis symptoms on teeth numbered 45. At radiographic examination, immature apex and deep caries lesion were observed and partial pulpotomy was performed by using calcium hydroxide to maintain vitality of the pulp and allow continued development of root dentin expecting the root will attain full maturity. Clinical and radiographic follow-up demonstrated a vital pulp besides not only closure of the apex (apexogenesis), but also physiologic root development (maturogenesis) after 1 year. Partial pulpotomy is an optional treatment for cariously exposed immature permanent teeth for preserving vitality and physiological root development.

    Full Text Available The retention of pulpally involved deciduous tooth in a healthy state until the time of normal exfoliation remains to be one of the challenges for Pedodontists. A scientific noise has been generated about several materials some of which have been popular pulpotomy medicaments. Concerns have been raised about the toxicity and potential carcinogenicity of these materials, and alternatives have been proposed to maintain the partial pulp vitality, however to date no material has been accepted as an ideal pulpotomy agent. Mineral trioxide aggregate (MTA is a biocompatible material which provides a biological seal. MTA has been proposed as a potential medicament for various pulpal procedures like pulp capping with reversible pulpitis, apexification, repair of root perforations, etc. Hence the present study was done to evaluate the efficacy of MTA as a pulpotomy medicament. A clinical and radiographic evaluation was done on children where MTA was used as pulpotomy medicament in primary molars for a period of 6 months and it was found to be a successful material.

    This in vivo study aimed to assess and compare the relative clinical and radiographic success of formocresol, glutaraldehyde and ferric sulphate as medicaments following pulpotomies in primary molars at three-monthly intervals over one year. The study was carried out on 90 primary molars in 54 children aged from 3 to 9 years. Selected teeth were equally distributed and randomly assigned to formocresol, glutaraldehyde and ferric sulphate pulpotomy medicament groups (30 in each group). The teeth were then evaluated clinically and radiographically at three-monthly intervals over one year. The resulting data were tabulated and statistically analysed using the chi-square test. After one year, the clinical success rate was 100% with glutaraldehyde, 96.7% with ferric sulphate, and 86.7% with formocresol. The radiological success rate gradually decreased over the year in all pulpotomy medicament groups. Radiological success rates in formocresol, glutaraldehyde, and ferric sulphate groups were 56.7%, 83.3%, and 63.3%, respectively. Two per cent glutaraldehyde may be recommended as a more effective alternative to formocresol and ferric sulphate as a pulpotomy medicament.

    Alternatives to vital pulpotomy treatment in primary teeth are being sought because of the high formaldehyde content of traditional formocresol (FC) pulpotomy medicaments. The aim was to compare the clinical and radiographic success of vital pulpotomy treatment in primary molars using 3% sodium hypochlorite (NaOCl) versus a 1:5 dilution of Buckley's FC. Pulpotomies were performed in primary molars of healthy children between 3 and 10 years old. Sixty-five primary teeth were randomized into two groups that were evaluated for treatment outcomes. Following treatment, the pulp chamber was filled with zinc oxide eugenol (ZnOE) and restored with a stainless steel crown cemented with glass ionomer cement. Clinical and radiographic outcomes were recorded at 6 and 12 months. The control (FC) and experimental (NaOCl) groups demonstrated 100% clinical success at 6 and 12 months. The NaOCl group had 86% (19/22) radiographic success at 6 months and 80% (12/15) at 12 months. The FC group had 84% (21/25) radiographic success at 6 months and 90% (9/10) at 12 months. No significant differences were found in the radiographic outcomes between the two groups at 6 and 12 months (Fisher's exact test; P=0.574 and P=0.468, respectively). NaOCl demonstrated clinical and radiographic success comparable to FC. © 2012 The Authors. International Journal of Paediatric Dentistry © 2012 BSPD, IAPD and Blackwell Publishing Ltd.

    The aim of this randomised clinical trial was to compare the clinical and radiographic success rate of 5% sodium hypochlorite (NaOCl) and 20% Formocresol (FC) as a pulpotomy medicament in carious primary molars. Twenty-four children aged 4-8 years with at least 2 primary molars indicated for pulpotomy were included in this study. Eighty-two teeth received either 5% NaOCl or 20% FC using split mouth design, followed by restoration with IRM base/stainless steel crown (SSC). Clinical and radiographic evaluations were performed at 3, 6 and 12 months. NaOCl and FC groups demonstrated 100% clinical success at 3 months. At 6 months, NaOCl showed 95% and 87.5% clinical and radiographic success rate respectively, while FC showed 95% clinical and radiographic success rate. After 12 months, the clinical and radiographic success rates were 94.6% and 86.5% respectively for NaOCl, and 92.1% and 86.8% for FC. The results of this study showed the success rate for NaOCl pulpotomy to be comparable to those for FC pulpotomy.

    The purpose of this study was to compare the clinical and radiographic success rates of two different pulpotomy agents: one novel agent, the biologically active odontogenic protein enamel matrix derivative (EMD) versus formocresol (FC). A randomized, single-blind, split-mouth study was used with a sample of 15 children aged 4 to 7 years (mean age, 5 +/- 0.73 years). A total of 15 pairs of teeth, 1 pair per child, were selected for treatment. One tooth from each pair was randomly assigned to either the EMD pulpotomy group or the FC pulpotomy group. All teeth were followed up clinically and radiographically at 2, 4, and 6 months. After 6 months, the clinical success rates for the FC and EMD groups were 67% and 93%, respectively. Although most likely clinically relevant, the clinical success rate difference after 6 months was not statistically significant. After 6 months, the radiographic success rates for the FC and EMD groups were 13% and 60 %, respectively. There was a statistically significant difference at p < or = 0.05. The clinical and radiographic assessment of EMD pulpotomized teeth in this study offers preliminary evidence that EMD is a promising material which may be as successful, or more so, than other pulpotomy agents.

    The aim of this study was to compare the clinical and radiographic success rates of 3 pulpotomy techniques: formocresol, calcium hydroxide, and calcium hydroxide/iodoform. The pulpotomies were performed by fifth-year undergraduate dental students. Members of senior staff at the clinics supervised all of the procedures. Informed consent was obtained from each child's parents. The teeth were randomly assigned to the experimental (calcium hydroxide and calcium hydroxide/iodoform) or control (formocresol) groups. After coronal pulp removal and hemostasis, remaining pulp tissue was covered with calcium hydroxide or calcium hydroxide/iodoform paste in the experimental groups. In the control group, formocresol was placed with a cotton pellet over the pulp tissue for 5 minutes and removed; the pulp tissue was then covered with zinc oxide-eugenol. All teeth were restored with stainless-steel crowns. Clinical and radiographic successes and failures were recorded at 1-, 3-, 6-, and 12-month follow-ups by the authors. Data were statistically analyzed using chi-squared tests. The follow-up evaluations revealed that the clinical success rates were 89.7% for formocresol, 33.3% for calcium hydroxide, and 17.2% for calcium hydroxide/iodoform. The radiographic success rates were 89.7% for formocresol, 33.3% for calcium hydroxide, and 13.8% for calcium hydroxide/iodoform. Formocresol was superior to calcium hydroxide and calcium hydroxide/iodoform pastes for primary molar pulpotomies. Internal resorption was the most common radiographic failure in all 3 pulpotomy techniques.

    The purposes of this investigation were to 1) measure success of a primary tooth pulpotomy technique that applies formocresol in the sub-base without the common five-minute application of a formocresol impregnated cotton pellet; and 2) compare success rates of the pulpotomy procedure using traditional criteria found throughout the literature with new criteria recently established, excluding internal resorption as a radiographic failure. Clinical and radiographic data were collected from a retrospective chart review of patients receiving formocresol pulpotomies with the application of formocresol in the zinc oxide-eugenol sub-base. Clinical and radiographic data were available for 196 primary molars in 122 children (followup=six to 103 months; mean=49 months). Traditional assessment of radiographic success and failure yielded a success rate of 79%. Alternative assessment excluding internal resorption as a failure yielded a 99% success rate. Most frequently observed pulpal responses were calcific metamorphosis and internal resorption. Overall clinical success was 99%. Two of the 196 teeth were extracted due to failure. A survival analysis demonstrated that the overall probability of survival remained high over time with a cumulative survival of over 95% after six years. The overall success rates in this study indicate that the formocresol pulpotomy technique incorporating formocresol in the zinc oxide-eugenol sub-base is a very successful treatment modality for primary molars requiring pulp therapy.

    The International Agency for Research on Cancer (IARC) has classified formaldehyde as carcinogenic to humans, leaving the dental profession to look for viable substitutes to formocresol in the vital pulpotomy technique. This study was designed to examine the attitudes and practices of Community Dental Service (CDS) staff in Wales in relation to vital pulpotomy for primary molars 18 months following the IARC's press release. The study employed a postal questionnaire. Questionnaires were returned by 79 (78.2%) of the CDS staff surveyed, yielding a sample of 65 dentists practising the technique. The most commonly used pulpotomy agents were formocresol, paraformaldehyde and ferric sulphate. Twenty-seven (41.5%) dentists expressed concern regarding their preferred pulpotomy agent and 17 (26.2%) were considering changing their technique. Only one respondent (1.5% of the sample) routinely took preoperative radiographs; follow-up radiographs were routinely taken by only three dentists (4.6%). Only 44 respondents (67.7%) always used local anaesthesia for this form of treatment. Amalgam was the most commonly used restorative material. Twenty-two respondents (33.8%) stated that they would pulp treat a primary molar on more than one occasion. The results of this study suggest that there is need for relevant continuing professional development courses for CDS staff in Wales.

    Introduction: The aim of this randomized clinical trial split-mouth study was to compare the postoperative pain following use of mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cement as pulpotomy agents in carious primary molars. Methods and Materials: Forty-seven children aged between 6-10 years old were enrolled in this study. Each child had two cariously involved primary molar in need of pulpotomy. After caries removal and preparing access cavity in one of the carious teeth, either MTA or CEM cement was randomly used as the pulpotomy agent, while the other cariously involved primary molar tooth was capped with the other material in a separate visit. After covering the radicular pulp with one of the capping materials the teeth were permanently restored with stainless steel crown (SSC). Postoperative pain was recorded by using Wong-Baker faces pain rating scale (Wong-Baker FPRS) up to seven days following the treatment. Data was analyzed using the Wilcoxon, McNemar, and chi square tests. Results: Forty-five patients fulfilled the treatment procedure and returned the Wong-Baker FPRS forms. Overall 65.6% of the patients reported pain irrespective of the pulpotomy agents used. There was no significant difference in postoperative pain between the teeth that received either MTA or CEM cement as pulpotomy agents in the first, second and the third day (P=0.805, P=0.942, P=0.705, respectively) following the procedure. The trend of the pain scores showed decreasing manner during the study period for the teeth in either groups of MTA or CEM cement. There was no significant difference between the two groups in the number of analgesics used following the treatment (P>0.05). Conclusion: The findings of the present study showed that a majority of the children felt pain following pulpotomy and SSC placement; however, there was no significant difference in pain reported when either MTA or CEM cement was used as pulpotomy agents.

    Full Text Available Statement of Problem: Pulpotomoy is considered as one of the most common treatments among primary teeth. Therefore, search for an appropriate and safe material seems necessary. Studies have proved ferosulfate as a therapeutic material in pulpotomy. Purpose: The goal of the present study was to compare clinical and radiographic changes of pulpotomy using ferosulfate and formocresol in primary molars among 3-8 year old children. Materials and Methods: In this clinical trial study, fifteen 3-8 years old children, referred to the pedodontics department, faculty of Dentistry, Tehran University of Medical Sciences were selected. All subjects did not show any systemic disease, with at least two clinically and radiographically accepted posterior teeth for pulpotomy technique. Totally, forty- three teeth were studied. For each patient both materials were used. Following treatment, patients were investigated, clinically and radiographically in 3, 6, 9 and 12 month follow-ups. During follow-up periods, teeth with failures were not excluded and investigated. For data analysis, Chi-square and Fisher’s-exact tests were used and treatment success was evaluated, based on clinical as well as radiographic findings. Results: In all follow-up periods (3, 6, 9 and 12 months after treatment, pulpotomies with formocresol showed more success rate (73.7% comparing to those with ferosulfate (70.8%, although the difference was not statistically significant (P>0.05. Statistical tests revealed no significant difference between two different treatment techniques regarding pain, external and internal resorption, calcified metamorphosis, abcess, apical root resorption, apical and interradicular radiolucency. Conclusion: Although ferosulfate, due to its less toxicity, may be considered as a proper substitute for formocresol in primary molars pulpotomies, more studies with longer-term follow up and larger sample size are required to determine its long-term effects.

    The objective of this study was to compare the effects of ferric sulphate (FS) to that of the full strength of formocresol (Buckley's formula) (FC) as pulpotomy agents in primary human molar teeth 42-48 months after treatment. This was to assess the succeeding premolar teeth for decalcification, abnormal morphology or any other defect. Seventy children, ranging in age from 3 to 6 years, mean 4.3 years, were treated for pulpotomy of primary molars. Ferric sulphate 15.5% solution (applied for 15 seconds for 84 teeth) and formocresol solution (5 minutes procedure for next the 80 teeth) were used as pulpotomy agents. In both groups, pulp stumps were covered with zinc oxide eugenol paste. Permanent restorations were, in most cases, stainless steel crowns and in some of them amalgams. Follow-up clinical assessments were every 3 months and the radiographic follow-up time was 6, 20 and 42-48 months after treatment. The differences were statistically analyzed using the Chi square test. These revealed 96.4% clinical success rate in the FS and 97.5% in the FC groups. Radiographic success rate in the FS group was 92.0%, while 94.6% in the FC group. No statistical significant differences were found between the radiographic assessment of the two pulpotomy agents. Ferric sulphate showed similar clinical and radiographic success rate as a pulpotomy agent for primary molar teeth after long term evaluation period, compared with formocresol. Ferric sulphate, because of its lower toxicity, may become a replacement for formocresol in primary molar teeth.

    This study aimed to illustrate the treatment outcomes of mineral trioxide aggregate (MTA) pulpotomy in vital permanent teeth with carious pulp exposure. MTA pulpotomy was performed in 66 vital permanent teeth with carious pulp exposure including teeth with signs and symptoms of irreversible pulpitis and the presence of periapical radiolucency. Patients were assessed for clinical and radiographic outcomes by 2 examiners. The relationship between treatment outcomes and factors was analyzed by means of univariate analysis and binary logistic regression. Fifty patients (a total of 55 teeth) attended the follow-up examination. The age of the patients ranged from 7-68 years old (mean = 29 years old). For the follow-up period as far as 62 months, 48 teeth showed successful outcomes (success rate = 87.3%). Teeth with clinical signs of irreversible pulpitis and the presence of periapical radiolucency could be treated successfully by MTA pulpotomy with success rates of 84% and 76%, respectively.Three of 7 failed cases required pulpectomy after MTA pulpotomy to relieve painful pulpitis. Four other failed cases were asymptomatic, and failure was detected from radiographic examination. The relationship between treatment outcomes and treatment factors could not be detected statistically. Teeth with carious pulp exposure can be treated successfully by MTA pulpotomy. Clinical signs of irreversible pulpitis and the presence of periapical radiolucency should not be considered as a contraindication for pulpotomy.

    Pulpotomy is the common therapy for cariously exposed pulps in symptom-free primary molar teeth. Formocresol (FC) is considered the gold standard dressing agent for pulpotomy, but concerns have been raised over the years about its safety. Other alternative pulpotomy agents have been investigated and suggested. The objective was to evaluate and compare the clinical and radiographic response of FC and white mineral trioxide aggregate (MTA) as pulpotomy materials on primary molars. Fifty primary molars, with deep carious lesion that exposed a vital but asymptomatic pulp, in 37 children aged 4-7 years were treated with conventional pulpotomy procedure. The teeth were divided randomly into two groups. Group I (FC) and group II (MTA). The treated teeth were evaluated clinically and radiographically and were followed-up for 12 months. At the end of the 12 months follow-up, the clinical success rates for FC and MTA were 81% and 100%, respectively. There was a statistically significant difference ( P = 0.04) between the clinical success rates of FC and MTA. While the radiographic success rates for FC and MTA were 81% and 96%, respectively, there was no statistically significant difference between the radiographic success of MTA and FC. White MTA showed a higher clinical and radiographic success rate when compared to FC as a pulpotomy agent in vital primary molars, and it has a potential to become a replacement for FC in primary molars.

    The primary aim of the following study is to evaluate and secondary aim is to compare clinically and radiographically the success of using white mineral trioxide aggregate (MTA) versus formocresol (FC) medicament for primary tooth pulpotomy. A total of 100 teeth were selected for pulpotomy; of which 50 teeth underwent FC pulpotomy and 50 teeth underwent pulpotomy with white MTA. Out of 100 treated teeth, 82 teeth (42 FC and 40 MTA teeth) were available at the end of 24 months for evaluation. 4 failures were found in FC group at 1 st month evaluation and no failures were found in white MTA group. A statistical analysis was performed to evaluate the overall success rate of study and individual success rates of medicaments. Overall success rate of the study was 95%, success rate of FC group was 90.48% and success rate of MTA group was 100%. MTA produced better results as pulpotomy medicament in comparison to FC. The superior success obtained in the present study was matching other studies mentioned in the literature. MTA seems to be a promising pulpotomy medicament for future use.

    The purpose of this study was to assess whether the diode laser (DL) pulpotomy method is a suitable alternative to formocresol (FC) and ferric sulphate (FS) pulpotomies in human primary teeth. Pulpotomy is the amputation of infected coronal pulp to maintain radicular pulp vitality and function. Although FC is regarded as the gold standard for pulpotomy in primary teeth, concerns about its safety have been reported. Lasers are an effective nonpharmacological alternative for treating pulp in children. This study included 120 primary molars in 58 children 5-9 years of age who underwent an identical conventional pulpotomy technique; the molars were allocated to FC, FS, and DL groups. After removal of the coronal tissue, complete hemostasis of the remaining pulp in the DL group was achieved by DL at 1.5 W, 30 Hz, and 50 mJ, with a 10 sec exposure time. For the FC group, diluted FC (1:5 Buckley's formocresol) was used for 5 min., and for the FS group, a 15.5% FS solution was used for 15 sec. Treatments in all groups were completed with stainless steel crowns and monitored clinically and radiographically at 1, 3, 6, 9, and 12 months. The clinical success rates at 12 months were 97%, 95%, and 100%, whereas the radiographic success rates were 87%, 79%, and 75%, for the FC, FS and DL groups, respectively. The differences in the results were not statistically significant according to the χ(2) test (p>0.05). DL pulpotomy offers a high clinical success rate, however considering radiographic success rate, it may not replace traditional FC and FS pulpotomies in primary molars.

    Full Text Available To use mineral trioxide aggregate (MTA in prophylactic management of talon cusp. Talon cusp is an endodontic oddity that possesses a treatment challenge to the clinician, especially when it causes esthetic and functional problems. Management ranges from periodic gradual reduction to radical removal followed by vital pulp/endodontic therapy. MTA has replaced calcium hydroxide as pulp capping material because of its superior properties. A 12-year-old boy reported with a complaint of irregular teeth. Clinical and radiographic examination revealed talon cusp on maxillary left central incisor. Radical removal of talon cusp and MTA pulpotomy was performed. The 4-year follow-up showed the positive pulp vitality test without any radiographic changes, emphasizing the use of MTA pulpotomy in successful management of talon cusp.

    The purpose of this study was to compare clinical, radiographic, and histopathologic effects of Nd:YAG laser pulpotomy to formocresol pulpotomy on human primary teeth. Patients with at least two vital primary molar teeth that required pulpotomy, because of pulpal exposure to caries, were selected for this study. After hemorrhage control, complete hemostasis into the canal orifice was achieved by exposure to Nd:YAG laser (1064 nm) and an He-Ne laser (the aiming beam of the Nd:YAG laser) in noncontact mode at 2 W, 20 Hz, 100 mJ, or was achieved by applying 1:5 dilution of formocresol. Forty-two teeth in two groups were to be followed up clinically and radiographic at 1, 3, 6, 9, and 12 months. Eighteen teeth planned for serial extractions were selected for histopathologic study. The teeth were extracted at 7 and 60 days. The teeth in the laser group had a clinical success rate of 85.71% and a radiographic success rate 71.42% at 12 months. The teeth in the formocresol group had a clinical and radiographic success rate of 90.47% at 12 months. There were no statistically significant differences between laser and formocresol group with regard to both clinical and radiographic success rates. There was a statistically significant difference between 7- and 60-day laser groups with regard to inflammatory cell response criteria. Dentin bridge was absent in all samples. No stained bacteria were observed in any of these samples. In conclusion, Nd:YAG laser may be considered as an alternative to formocresol for pulpotomies in primary teeth.

    Formocresol remains to be the preferred medicament in pulpotomy, despite the concerns regarding tissue devitalization and systemic toxicity. Several materials were used as alternatives, but none proved significantly advantageous. Of recent, calcium phosphate cement (CPC) has been projected as an ideal pulpotomy material considering its tissue compatibility and dentinogenic properties. This study explores the suitability of a CPC formulation for pulpotomy, in comparison with formocresol. This comparative case study included 10 children (8-12 age group) having a pair of non-carious primary canines (both maxillary and mandibular) posted for extraction. Pulpotomy was performed with CPC in the right canines and formocresol in the left and sealed with IRM ® (Dentsply). The teeth were extracted at 70 ± 5 days and sectioned and stained for the histopathological evaluation. Parameters such as pulpal inflammation, tissue reaction to material, dentine bridge formation, location of dentine bridge, quality of dentine formation in bridge, and connective tissue in bridge etc. were evaluated. The histological assessment after 70 days showed no statistically significant difference between the two groups in any of the parameters. However, CPC gave more favorable results in pulpal inflammation, with a lower score of 1.6 against 2.6 for formocresol. CPC samples showed better formation of dentine bridge in quantity and quality. The mean scores for CPC for the extent of dentine bridge formation, quality of dentine bridge and connective tissue in the bridge, were 2.0, 1.4, and 1.2 respectively, whereas the corresponding values for formocresol were 0.8, 0.2, and 1.0. CPC is more compatible to pulp tissues than formocresol and it shows good healing potential. CPC is capable of inducing dentine formation without an area of necrosis.

    Formocresol, though the center of much controversy is still the most widely used medicament for primary teeth pulpotomy and an intracanal medicament which has undergone a lengthy evolution to shorten the formocresol application time and reduce the concentration of formocresol exposure to the pulp tissue. Hence, the determination of the actual effective dose and concentration of formocresol for clinical application in primary teeth is an important area of research and a thorough clinical, radiographic and histological investigation in human subjects is very much needed. The study was conducted on 45 primary molars for the Clinical, Radiographic study and 45 premolars orthodontically indicated for extraction for the Histological study. The samples were randomly and equally divided into 3 groups of 15 each for pulpotomy with full strength formocresol, 1:5 diluted formocresol and 1:25 diluted formocresol respectively. The pulpotomized primary molars were clinically evaluated at 1st, 3rd, 6th and 9th month while the pulpotomized premolars were subjected for histological evaluation after extraction. Obtained by chi-square test revealed that all the pulpotomized primary molars were asymptomatic till the end of the study period; suggesting 100% clinical and radiographic success while histologically, the three concentrations of formocresol showed decreased severity of fixation of the pulp tissue with decreasing concentration of formocresol. It can be inferred that the diluted formulations (1:5 and 1:25) of formocresol are equally efficient when compared to full-strength formocresol and thus, can be recommended for pulpotomy in primary teeth.

    There is scant evidence supporting the criteria for establishing the suitability of a deciduous molar for a pulpotomy. Although some criteria, such as patient age, are logical the importance of other factors on tooth survival has not been established. All pulpotomies performed at 20 school dental clinics over a period of 15 months were reported together with date of birth, gender, tooth treated, presenting signs and symptoms, pulp status and date and method of treatment. Operators performed the treatment according to their usual procedures. Data were analysed statistically using Statview 5.0 (SAS Institute). The outcome of pulpotomy of 465 deciduous teeth in 403 patients was evaluated. The mean age of the patients was 7.4 +/- 0.1 years. Two hundred and seventy-two teeth were vital and 193 were non-vital. One hundred and ninety-six teeth were treated with the one-step formocresol method and 269 with the two-step formocresol method. The age and gender of the patients did not differ between the vital and non-vital groups. There was no influence of mode of treatment on the asymptomatic survival of the teeth in the mouth. The median survival times were significantly longer in vital (32.7 +/- 1.4 months) than non-vital teeth (20.4 +/- 3.0 months; p < 0.0001). The only factors significantly influencing the survival of pulpotomized teeth were the age of the patient (p < 0.0001), the non-vitality of the pulp (p < 0.0001) and the presence of a radiolucency (p = 0.031). Both vital and non-vital teeth were able to survive for extended periods following pulpotomy but the presence of an associated radiolucency or a non-vital pulp at the time of treatment is negatively associated with time of survival.

    Full Text Available Aim: This study aims to evaluate the clinical, radiographic, and histological success rate of antioxidant mix as a new pulpotomy agent for primary teeth. Settings and Design: Commercially available antioxidants, namely Antioxidants plus trace elements (OXIn-Xt tm , India were used. Materials and Methods: This prospective study was carried out on 36 primary molar teeth in 32 children, with age that ranged from 6 to 9 years. Regular conventional pulpotomy procedure followed by placement of antioxidant mix over the radicular orifice was done. Recall was scheduled for 3, 6, and 9 months, respectively, after treatment. Results: Thirty-six pulpotomized primary molars were available for follow-up evaluations. Scanning electron microscopy analysis of samples showing convex shaped hard tissue barrier formation may be proof of the role of antioxidant material in localization and direction and morphology of the hard tissue barrier. One tooth which presented with pain was assessed as unsuccessful. Conclusion: Quite promising clinical, radiographic, and histological results of antioxidants in the present study shows their potential to be an ideal pulpotomy agent.

    Pulpotomy is the most performed and controversial therapeutic in pediatric dentistry. Since formocresol is known to have a toxic effect on living tissues, plus a mutagenic and carcinogenic potential with a systemic uptake of formocresol via pulpotomized teeth, other alternative products have been investigated. Twenty-five decayed primary canines and twenty-five healthy primary canines necessitating disking for orthodontic purposes were pulpotomized using non modified Zinc Oxide Eugenol. The effects of this material were evaluated both clinically and radiographically. Post operative control examinations were performed at 1, 6, 12, and 24 months trying to detect spontaneous or stimulated pain, pathological tooth mobility, abscesses or fistulas, internal or external pathological tooth resorption, periapical bone destruction, or canal obliteration. Pain was absent at 24 months post operatively. Half of the treated canines presented with a mobility, while internal and external resorptions were more frequent in decayed teeth and their number increased with time. On the other hand, abscesses and fistulas were equally found in both treated groups. The observations were compared to others related to formocresol ferric sulfate, MTA, and laser pulpotomies, using the binominal law, or the comparative test of an observed proportion to a reference proportion. In this study, and based on the excessive negative results in both groups, we demonstrated that non fixative pulpotomies on temporary canines were not a promising technique.

    Introduction. The etiology of exposure determines pulpal response, making it crucial to distinguish between mechanical and carious exposure. This study clinically and radiographically evaluated the success of MTA pulpotomies conducted to treat carious and mechanical pulp exposure. Materials and Methods. This study was conducted with 50 mandibular primary molar teeth. Teeth were divided into 2 groups according to status of the exposure site, with teeth surrounded by carious dentin placed in a carious exposure group and those surrounded by sound dentin in a mechanical exposure group. MTA pulpotomies were performed for both groups. Treatment was followed up clinically and radiographically for 18 months. Results. Clinical and radiographic success rates at 18 months were 100% for both groups. Success rates did not vary significantly between the groups (p = 1.000). Pulp canal obliteration was only seen in the carious exposure group, observed in 2 teeth (8.3%). Conclusion. The long term success rates achieved in this study indicate that MTA can be used as a vital pulpotomy material for the long term success in primary teeth with either mechanical or carious exposure. The findings of the present study highlight the fact that treatment prognosis is dependent upon diagnosis and selection of the appropriate materials for treatment. PMID:27995139

    Objectives: To evaluate the outcome of vital pulp therapy in primary teeth with irreversible pulpitis by using calcium-enriched mixture (CEM) cement according to clinical and radiographic assessment. Participants and Methods: Fifty primary molar teeth with irreversible pulpitis in 50 children aged 6-8 years underwent pulpotomy using CEM cement as the dressing material. Following pulpotomy, pain intensity was evaluated by use of a visual analog scale at 1 and 7 days from the treatment and in clinical appointments at 3, 6 and 12 months after baseline. Radiographic evaluation was performed at 6 and 12 months. Data were analyzed using the McNemar test. Results: A total of 42 children (mean age 7.26 ± 0.82 year) completed the study. After one day treatment 56 % of children reported complete relief of pain and after 7 days 62% reported the same. However, two children complained of increased pain 1 day after treatment. None of the children reported pain in the subsequent appointments. One child complained of tenderness in percussion after 6 months. Pulp canal obliteration was the most common change in the radiographic assessment. There was no significant difference between clinical (92.8%) and radiographic (90.4%) success (p=0.990). Conclusion: Pulpotomy using CEM cement could present a successful treatment in primary molar teeth with irreversible pulpitis. PMID:27326265

    Full Text Available Introduction: This case report conveys the prognosis of partial pulpotomy treatment of complicated crown fractures in maxillary permanent incisors using white Mineral Trioxide Aggregate (wMTA or calcium hydroxide in a 9 year-old boy. Case report: The patient was referred to the clinic with complicated crown fractures in both maxillary central incisors due to trauma. Partial pulpotomy was done in both teeth. Calcium hydroxide was selected as a conventional pulp capping agent for tooth number 11 and wMTA was selected for tooth number 21. Unfortunately, 3 months later, the patient had a secondary trauma to tooth number 11 necessitating endodontic treatment, fiber-post and strip-crown restoration. Six months later, discoloration was observed in tooth number 21. The colored material including wMTA and the dentin was removed under operating microscope and the restoration was renewed. Microbiological evaluation of the removed material showed negative culture for aerobic and anaerobic bacteria, and fungus. The tooth number 21 remained vital and a dentin bridge was confirmed clinically and radiographically at 12 and 24 months follow-up visits and there was no further esthetic problem. Conclusion: As a result, it can be concluded that the use of wMTA for partial pulpotomy needs to be reconsidered for esthetical reasons.

    Purpose. The purpose of this study was to evaluate clinical and radiographic findings of treatments using a new hemostatic agent (Ankaferd blood stopper (ABS)), as compared to ferric sulfate (FS), when used as a pulpotomy medicament in primary teeth. Materials and Methods. The primary molars (70) were selected from 35 children aged 4 to 6 years. The teeth were randomized into two groups for pulpotomy with the ABS (n = 35) and the FS (n = 35) agents. The patients were recalled for clinical and radiographic evaluation at 3-, 6-, 9-, and 12-month intervals. Results. At the 3- and 6-month clinical and radiographic evaluations, total success rates of 100% were observed in each group. In ABS and FS groups, the clinical success rates, however, reduced to 90.9% and 93.9% at the 9-month examination and 84,8% and 90.9% at the 12-month examination, respectively. Similarly, the teeth in the ABS and FS groups had radiographic success rates of 90.9% and 93.9% at 9 months and 84.8% and 87.8% at 12 moths, respectively. Conclusion. Although the findings indicated that ABS agents may be useful agents for pulpotomy medicament, further long-term and comprehensive histological investigations of ABS treatments are necessary.

    To apply meta-analysis to compare the clinical and radiographic effects of mineral trioxide aggregate (MTA) with formocresol (FC) when used as wound dressing for pulpotomy of primary molars. The study list was obtained by searching MEDLINE, The Cochrane Library, EMBASE, and SCI. Only those papers that met the inclusion criteria were analyzed. Six studies met the inclusion criteria. There was significant difference between the success rates of FC- and MTA-treated pulpotomized primary molars (P < .05). Clinical assessments and radiographic findings of the MTA versus FC pulpotomy suggested that MTA was superior to FC in pulpotomy resulting in a lower failure rate, with the RR (Relative Risk) being 0.32 (95% confidence interval [CI] 0.11 to 0.90) and 0.31 (95% CI 0.13 to 0.74), respectively. Internal root resorption happened less in the MTA group with RR 0.29, 95% CI 0.11 to 0.77. MTA induces less undesirable responses and might be FC's suitable replacement.

    The objective of this study was to assess the effect of mineral trioxide aggregate (MTA) as pulp dressing material following pulpotomy in primary molars with carious pulp exposure and compare them to those of formocresol (FC). Of 33 children, primary molars treated via a conventional pulpotomy technique were randomly assigned to the MTA group (33 teeth) or FC group (29 teeth). Clinical and radiographic follow-up ranged between 4 and 74 months. The mean follow-up time was 38 months, with no difference between the groups. Twenty-nine teeth were followed until uneventful shedding (mean=33 months). Failures were detected after a mean period of 16 months (range=4 to 30). The success rate of pulpotomy was 97% for MTA (1 failure) and 83% for FC (5 failures). Eight teeth presented internal resorption. In 4 of them (2 of each group), progress of the resorption process stopped and the pulp tissue was replaced by a radioopaque calcified tissue. Pulp canal obliteration was observed in 58% of the MTA group and in 52% of the FC group (total=55%). MTA showed a higher (though not statistically significant) long-term clinical and radiographic success rate than formocresol, and can be recommended as its replacement as, unlike FC, MTA does not induce undesirable responses.

    There are various studies looking at the effects of formocresol (FC) and mineral trioxide aggregate (MTA) on pulpotomy of primary molars. This is a systematic review of literature comparing the success rates of MTA and FC in pulpotomy of primary molars. The study list was obtained using PubMed, EMBASE, Scopus, Science Citation Index, Iran Medex, Google Scholar, the Cochrane Library, and also some hand searches contains through dental journals approved by the Iranian Ministry of Health. Papers which met the inclusion were accepted. The quality of studies for the meta-analysis was assessed by a series of validity criteria according to Jadad's scale. Eight qualified studies met the criteria. Terms of clinical outcomes and radiographic findings were evaluated in all studies to assess clinical success and root resorption. Fixed model was applied to aggregate the data of homogenous studies. A random effect model was carried out for measuring the effect size of heterogeneous studies. The overall clinical and radiographic success rates based on the data suggested that MTA was superior to FC (P=0.004) with the Odds Ratio=3.535 and 95% confidence interval (1.494-8.369). Primary molars pulpotomy with MTA have better clinical and radiographic success rates than FC. (Iranian Endodontic Journal 2008;3:45-9).

    The purpose of this retrospective study was to evaluate the radiographic findings with formocresol and ferric sulfate pulpotomies in relation to early tooth loss. Vital pulpotomies with either ferric sulfate or formocresol, performed by faculty members between 1992 and 2002 at The University of Iowa, were evaluated retrospectively. Radiographic criteria were established to assess success or failure of the treated tooth. This was then correlated with time of tooth loss and space management. Eighty-five molars, followed between 6 to 61 months, met the inclusion criteria. Of these, 15 (43%) teeth treated with ferric sulfate, 23 (56%) treated with formocresol, and 5 (55%) treated with a combination of ferric sulfate and formocresol remained free of any radiographic pathology. Overall, 13% of the pulpotomized teeth were prematurely lost due to abscess formation and in need of space management. Regardless of the treatment type, internal root resorption was the most common cause of premature exfoliation. Both ferric sulfate and formocresol pulpotomies can lead to premature exfoliation of primary teeth, with the subsequent need for orthodontic space maintenance. Therefore, radiographic criteria should be taken into consideration when evaluating pulpotomized teeth at recall visits.

    Formocresol and ferric sulfate were evaluated as pulpotomy medicaments using evidence-based dentistry principles. Formocresol has been challenged as a potential carcinogen and mutagen, leading to consideration of ferric sulfate. The PICOT statement was: (P) In human carious primary molars with reversible coronal pulpitis, (I) does a pulpotomy performed with ferric sulfate, (C) compared with formocresol, (O) result in dinical/radiographic success, (T) in time periods up to exfoliation? Relevant papers (N=894) were identified from databases and inclusion criteria were applied; 94 papers remained (randomized clinical trials [RCTs]=7; clinical trials [CTs]=28; case-control studies=14; opinions, cohort, and cross-sectional studies=4; reviews=22; irretrievable papers=19). Three RCTs and 10 CTs (total teeth: formocresol=753; ferric sulfate=90) were meta-analyzed; 1 RCT and 1 CT were tested for homogeneity (odds ratios; 95% confidence intervals); 3 RCTs and 10 CTs were examined by student's t test. Clinical data indicated ferric sulfate was significantly more successful than formocresol (OR=1.95; CI=1.01-3.80). Radiographic data indicated no difference between medicaments (OR=0.90; CI=0.58-1.39). Medicaments did not differ with t-tests of clinical (P>.10) and radiographic (P>.50) data. This evidence-based assessment concluded that, in human carious primary molars with reversible coronal pulpitis, pulpotomies performed with either formocresol or ferric sulfate are likely to have similar clinical/radiographic success.

    The purpose of this study was to evaluate the total success rates of mineral trioxide aggregate (MTA), ferric sulfate (FS), and formocresol (FC) as pulpotomy agents in primary molars. A randomized, split-mouth study design was used in 32 healthy 5- to 7-year-old children with 128 carious primary molars without clinical or radiographic evidence of pulp degeneration. The pulpotomy agents were assigned as follows: Group 1=MTA; Group 2=FS; Group 3=1:5 diluted Buckley's FC; and Group 4=zinc oxide eugenol (ZOE) base. Clinical and radiographic follow-up at 6, 12, and 24 months used the following criteria: pain; swelling; sinus tract; mobility; internal root resorption; and furcation and/or periapical bone destruction. The data were analyzed using chi-square. No significant differences in success rates were found among the groups at 6 and 12 months. Success rates in groups 1 to 4 at 24 months were 96%, 88%, 88%, and 68% respectively. There was a significant difference (P<.001) between the MTA and ZOE groups at 24 months. ZOE, as the only pulpotomy medicament, had a significantly lower success rate than MTA. No significant differences were observed, among the 3 experimental materials (MTA, FC, and FS) at 2 years follow-up.

    Full Text Available Objective: Low-level laser therapy (LLLT has been increasingly in use over the last few decades in both medicine and dentistry. It has been suggested that LLLT may be helpful in pulpal wound healing following pulp exposure. The purpose of this study was to comparethe effectiveness of LLLT and formocresol (FC application in healing of remaining pulp following pulp amputation in primary molars.Materials and Methods: A total of 23 contralateral pairs of teeth from 11 children aged 4 to 7 years were selected and matched using clinical and radiographic criteria. One toothfrom each pair was randomly assigned to the LLLT pulpotomy and the to FC pulpotomy group. During a 6-month follow-up period, the teeth were examined clinically and radiographically.Eight patients (four in each group completed six-month and 6 patients (threein each group completed one-year follow-up.Results: Clinically, no complication was observed in the teeth. However, radiographic assessment revealed signs of periradicular radiolucency in two teeth in LLLT group.Conclusion: Findings of this investigation show that LLLT can be used successfully as a complementary step to pulpotomy procedure in order to help the healing of amputated pulp. Longer follow-up periods are recommended to investigate long-term effect of LLLTpulpotomy on pulp.

    The study's purpose was to survey directors of pediatric dental residency programs in order to evaluate the materials currently being taught and used for pulpotomy procedures for primary teeth in educational and clinical settings. A web-based survey was emailed to all graduate pediatric dental residency program directors in the United States. Seventy one emails were sent to program directors, 47 responded but only 39 respondents (55%) were included in the study. Results suggested a slight decrease in utilization of formocresol 1:5 dilution (Pformocresol (18% of respondents) were systemic health concerns and carcinogenicity, in addition to evidence-based literature. Even though 25% of respondents have begun to use MTA for primary pulpotomy procedures, the most common reason for utilization of other medicaments over MTA was its higher cost. With 82% of graduate pediatric dental residency programs still utilizing formocresol 1:5 dilution for pulpotomy procedures in primary teeth, there has been no major shift away from its clinical use, in spite of increased usage of newer medicaments over the last 5 years.

    Pulpotomy is the most performed and controversial therapeutic in pediatric dentistry. Formocresol is known to have a toxic effect on living tissues, a mutagenic and carcinogenic potential with a systemic uptake of formocresol via pulpotomized teeth, other alternative products have been investigated. 40 molars were pulpotomized using Micro Mega Mineral Trioxide Aggregate (MM-MTA), which eliminates the need for the use of formocresol. The effects of this material were evaluated both clinically and radiographically. Post-operative control examinations were performed at 1, 6, 12, and 18 months trying to detect spontaneous or stimulated pain, pathological tooth mobility, abscesses or fistulas, internal or external pathological tooth resorption, periapical bone destruction, or canal obliteration. Pain was absent at 18 months post operatively. Thirty six molar treated with the MM-MTA didn't show any mobility or pain, one molar presented a pathological resorption and one molar presented an abscess without a fistula at 12 month. The observations were compared to others related to formocresol, ferric sulfate, MTA, and laser pulpotomies, using the Chi-square test x2. The abundance of positive result strongly demonstrate that the MM-MTA pulpotomy on carious temporary molars is a promising technique.

    The objectives of this study were to clinically evaluate the effectiveness of 2% buffered glutaraldehyde in pulpotomies of human primary molars and to compare the success rate of glutaraldehyde with calcium hydroxide and glutaraldehyde with zinc oxide eugenol as dressing material on the radicular pulp. Pulpotomies were completed on 61 primary molars in 19 children. The teeth were divided into two groups by random allocation. One group had a dressing of zinc oxide-eugenol base (IRM) incorporated with one drop of 2% buffered glutaraldehyde while the other group had a dressing of calcium hydroxide base incorporated with one drop of 2% buffered glutaraldehyde after the initial placement of 2% buffered glutaraldehyde on cotton pellet for 3 min. All teeth had light-curing compomer (Dyract) placed over the dressing material followed by a stainless steel crown restoration within 1 or 2 weeks after the pulpotomy. Blind clinical and radiographic evaluations of 57 teeth available after 12 months showed a success rate of 92.9% and 73.6% respectively. The clinical and radiographic success rates for glutaraldehyde/zinc oxide eugenol pulpotomies were 96.5% and 75.8% respectively while those for glutaraldehyde-calcium hydroxide were 89.2% and 71.4%. There was no statistically significant difference between the two groups either clinically or radiographically. The overall clinical success rate suggested that 2% buffered glutaraldehyde was an effective agent in the pulpotomy of human primary molars.

    Full Text Available This case report describes a pulpotomy treatment of a permanent mature molar tooth with established irreversible pulpitis and condensing apical periodontitis, using calcium-enriched mixture (CEM cement. Clinical examination revealed that the first right lower molar had a large carious lesion with history of spontaneous/lingering pain; radiographic examination showed condensing apical periodontitis. Pulpotomy was opted as the treatment; cervical pulpotomy was carried out. Following hemostasis, the radicular pulp stumps were covered with ~2-mm-thick layer of the prepared CEM cement; the tooth was restored with amalgam. Two-year follow-up showed that the treated tooth had been symptomless, and there were no clinical signs/symptoms of either inflammation or infection. Radiographically, the periradicular lesion was completely healed with reconstruction of bone structures to normal appearance; the root canals were not calcified. According to chemical, physical, and biological properties of the CEM cement, this novel biomaterial may be suitable for endodontic treatment.

    The purpose of this study was to investigate whether a diode laser pulpotomy with mineral trioxide aggregate (MTA) sealing could be an acceptable alternative to the conventional formocresol pulpotomy and zinc oxide eugenol (ZOE) sealing in human primary teeth. A randomized, single-blind, split-mouth study was used with a sample of 16 children aged from 3 to 8 years (mean age=5.10 years). A total of 26 pairs of teeth from these 16 patients were selected based on clinical and radiographic criteria. One tooth from each pair was randomly assigned to either the laser-MTA pulpotomy group or the formocresol-ZOE pulpotomy group. All teeth were followed up clinically and radiographically at 2.3, 5.2, 9.5 and 15.7 months. All extracted failures were sectioned and photographed to assess possible reasons for this. A total of seven laser-MTA-treated teeth were deemed to be radiographic failures (mean time until failure=9.1 months) compared to three formocresol-ZOE treated teeth (mean time until failure=12.5 months). These results were not significant using Fisher's exact test (P>0.05). Six of the laser-MTA failures and all three formocresol-ZOE failures exhibited furcal and/or periapical radiolucencies with or without pathologic root resorption. One of the laser-MTA failures displayed premature root resorption and is being observed for exfoliation. Analysis of photographs of teeth available for extraction revealed errors in clinical technique in addition to expected signs of a disease process such as the presence of granulation tissue and areas of pathologic root resorption. The laser-MTA pulpotomy showed reduced radiographic success rates compared to the formocresol-ZOE pulpotomy at 15.7 months; however, these results were not statistically significant. Improved success rates among a larger patient sample and a longer follow-up period would be required for the laser-MTA pulpotomy to be considered a routine alternative to the conventional formocresol-ZOE procedure.

    An ideal pulpotomy agent for primary molars has been sought for many years. Recently, new materials that allow regeneration of residual pulp tissue have been developed. In this study, we compared the preliminary clinical results obtained using Biodentine and mineral trioxide aggregate (MTA) as pulp-dressing agents in pulpotomies of primary molars. A randomized clinical study was performed in children aged 4-9 years with at least one primary tooth with decay or caries requiring pulp treatment. A total of 90 primary molars requiring pulpotomy were randomly allocated to the MTA or Biodentine group, and 84 pulpotomies were performed. Clinical and radiographic evaluations were undertaken 6 and 12 months after treatment. All teeth were restored with a reinforced zinc oxide-eugenol base and stainless steel crowns. Statistical analysis using Fisher's exact test was performed to determine the significant differences between the groups. A total of four clinical failures were observed; all involved gingival inflammation. The clinical success rate in the MTA Group after 12 months was 92 % (36/39), whereas the Biodentine Group obtained 97 % (38/39) (p = 0.346). All radiographic failures were observed at the 12-month follow-up evaluation. One molar from MTA Group showed internal resorption obtaining a radiographic success rate of 97 % (38/39). Two molars from the Biodentine Group showed radiographic failure (1 internal resorption and 1 periradicular radiolucency) obtaining a radiographic success rate of 95 % (37/39). Biodentine showed similar clinical results as MTA with comparable success rates when used for pulpotomies of primary molars. However, longer follow-up studies are required to confirm our findings. This article demonstrates the effectiveness of Biodentine as a primary teeth pulpotomy material, performing similar results as MTA at 12-months evaluation.

    Full Text Available Statement of Problem: Pulpotomy is the most common pulp treatment of primary molars. Formocresol pulpotomy has enjoyed long-term clinical use and success, but concerns over its toxicity and mutagenicity have prompted research into other pulpotomy techniques.Purpose: The aim of the present study was to compare the relative success of formocresol, ferric sulfate and MTA pulpotomy methods in primary molars, using clinical and radiographic examinations.Materials and Methods: 135 second primary molars requiring pulpotomy treatment were selected from children between 3 and 6 years of age. They were randomly assigned to three groups according to the pulpal therapy technique: pulpotomy with formocresol, ferric sulfate, and MTA. All pulpotomized teeth were restored with amalgam. The subjects selected for clinical and radiographic evaluations were monitored periodically for 3 and 12 months.Results: The clinical success rate of the MTA group was 82.1% after one year which was significantly less than the 100% observed in the other groups (P= 0.005.The highest and lowest radiographic success rates after one year, were encountered in the formocresol (92.5% and MTA (69.2% groups respectively, which showed a significant difference (P=0.01. The success rate of the ferric sulfate group was 80.50%.Conclusion: MTA is not recommended as a pulpotomy medicament in primary teeth,but ferric sulfate may be acceptable as an alternative to formocresol.

    Full Text Available Introduction: Ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. But the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to Formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide Eugenol paste. The aim of this study was to determine and compare the clinical and radiographic success rate of ferric sulfate pulpotomy of primary molars with zinc oxide eugenol and zinc polycarboxylate cements in order to determine the more suitable pulp capping material for ferric sulfate pulpotomy. Methods: In this randomized trial study, 140 primary molar teeth in children between3-5 years old, with the treatment plan of pulpotomy were randomly allotted to one of two groups; ferric sulfate pulpotomy with zinc oxide eugenol and zinc polycarboxylate cements. After treatment, pulpotomized teeth were double blindly evaluated clinically and radiographically and Fisher's exact test was used for analysis of data. Results: Clinical success rate in one year evaluation in two groups of zinc oxide eugenol and Zinc polycarboxylate was 98.1% and 93.9%, respectively that was not significantly different. (P=0.34. In one year evaluation, radiographic success rate was 96.30% in zinc oxide eugenol group and 91.8% in zinc polycarboxylate group but this difference was also not significant(P=0.42. Conclusion: In ferric sulfate pulpotomy, it is not preferable to use zinc polycarboxylate cements as a subbase instead of zinc oxide eugenol cement.

    A pulpotomy is the therapy for management of pulp exposures due to caries in symptom-free primary molars. The aim was to longitudinally compare the relative effectiveness of the Er:YAG laser, calcium hydroxide and ferric sulphate techniques with dilute formocresol in retaining symptom-free molars. Two hundred primary molars in 107 healthy children were included and randomly allocated to one technique. The treated teeth were blindly reevaluated after 6, 12, 18, 24 and 36 months. Descriptive data analysis and logistic regression analysis accounting for multiple observations per patient by generalised estimating equation were used. Additionally, various influences including tooth type, upper and lower jaws, type of anaesthesia, operator and the final restoration on treatment success were evaluated (Wald chi-square test). After 36 months, the following total (considering clinical and clinically symptom-free radiographic failures) and clinical success rates were determined (in percent): Formocresol 72 (92), laser 73 (89), calcium hydroxide 46 (75), ferric sulphate 76 (97). No significant differences were detected between formocresol and any other technique after 36 months. However, the odds ratio of failure appeared to be three times higher for calcium hydroxide than for formocresol. No significant differences in total success rates were seen regarding the aforementioned influencing clinical parameters. The correct diagnosis of the pulpal status, bleeding control and the specific technique are highly important for long-term success of pulpotomies in primary molars. According to the presented long-term data, pulpotomies using ferric sulphate revealed the best treatment outcome among the used techniques, while calcium hydroxide resulted in the lowest success rates after 3 years. Therefore, we can recommend ferric sulphate for easy and successful treatment of primary molars with caries-exposed pulps.

    Full Text Available "nBackground and Aims: Formocresol is one of the most common pulpotomy medicaments for primary teeth. Because of its systemic and local side effects, it may be essential to use another material instead of formocresol. The aim of this study was to evaluate the histopothalogy of pulp after pulpotomy teeth with sodium hypochlorite and formocresol. "nMaterials and Methods: In this randomized clinical trial, 22 canine teeth that must be extracted because of orthodontic treatment were selected. The teeth were randomly divided into 2 groups (n=11 and pulpotomized with formocresol or sodium hypochlorite. These teeth were extracted after 2 months and pulpal response was evaluated according to the degree of inflammation and extent of pulpal involvement. Dentinal bridge formation was also evaluated. The data were analyzed by Mann-Whitney test. "nResults: In formocresol group, mild inflammation was seen in 4 and moderate inflammation in 3 and severe inflammation in 4 cases. In sodium hypochlorite group mild inflammation was seen in 6 cases and moderate inflammation in 4 cases and severe inflammation in 1 case. Mann-Whitney test revealed that this difference was not statistically significant (P>0.05. In formocresol group, necrosis was seen in 5 cases, but abscess and internal resorption were not seen in any cases. In sodium hypochlorite group, internal resorption was seen in 3 cases; but necrosis and abscess were not seen in any cases.  Mann-Whitney test showed that the difference between two groups was significant in terms of necrosis (P=0.02. In sodium hypochlorite group, dentinal bridge was formed in 3 cases; however, no dentinal bridge formation was seen in formocresol group.

    This study's purpose was to compare the clinical and radiographic success rates of 5.25 percent Sodium Hypochlorite (NaOCl) pulpotomies to Formocresol (FC) and Ferric Sulfate (FS) in decayed primary molars. Eighty-one primary molars, randomly divided into three groups, were treated with one of three different pulpotomy materials; NaOCl, FC and FS. The outcomes of the different groups were assessed clinically and radiographically every six months over 18 months. Chi-square test was used to detect differences in outcome measures in all groups. At six months, clinical and radiographic success rates were 100 percent for each group (27/27). At 12 months, clinical success was 100 percent (24/24), 96 percent (24/25), and 95.7 percent (22/23) for NaOCl, FC, and FS respectively. The radiographic success was 95.8 percent (23/24) for NaOCl group, and 100 percent for FC (25/25), and FS (23/23). At 18 months, the clinical success was 83.3 percent (20/24), 96 percent (24/25), and 87 percent (20/23) for NaOCL, FC, and FS respectively. The 18 month radiographic success was 91.7 percent (22/24), 100 percent (25/25), and 95.7 percent (22/23) for NaOCl, FC, and FS respectively. No significant differences were found in clinical or radiographic outcomes between the three groups at six, 12 and 18 months. The three pulpotomy medicaments yielded similar outcomes.

    To compare the effectiveness of mineral trioxide aggregate (MTA), calcium hydroxide (CH) and formocresol (FC) as pulp dressing agents in carious primary teeth. Forty-five primary mandibular molars with dental caries in 23 children [AUTHOR QUERY: How many children?] between 5 and 9 years old were treated by a conventional pulpotomy technique. The teeth were randomly assigned to the experimental (CH or MTA) or control (FC) groups. After coronal pulp removal and haemostasis, remaining pulp tissue was covered with MTA paste or CH powder in the experimental groups. In the control group, diluted FC was placed with a cotton pellet over the pulp tissue for 5 min and removed; the pulp tissue was then covered with zinc oxide-eugenol (ZOE) paste. All teeth were restored with reinforced ZOE base and resin modified glass-ionomer cement. Clinical and radiographic successes and failures were recorded at 3, 6, 12, 18 and 24 month follow-up. Forty-three teeth were available for follow-up. In the FC and MTA groups, 100% of the available teeth were clinically and radiographically successful at all follow-up appointments; dentine bridge formation could be detected in 29% of the teeth treated with MTA. In the CH group, 64% of the teeth presented clinical and radiographic failures detected throughout the follow-up period, and internal resorption was a frequent radiographic finding. Mineral trioxide aggregate was superior to CH and equally as effective as FC as a pulpotomy dressing in primary mandibular molars. Internal resorption was the most common radiographic finding up to 24 month after pulpotomies performed with CH.

    This article reports a case of preserving pulp vitality combined with aesthetics and functional reconstruction of an immature permanent molar extensively destroyed because of a carious lesion. After a pulpotomy using calcium hydroxide, the tooth crown was restored by bonding a dental fragment obtained from an extracted tooth from another individual. Aspects of diagnosis and treatment that directly affect the prognosis of the techniques are discussed. Radiographic and clinical follow-up for two years showed complete root development and a very satisfactory restoration with regard to aesthetics and function.

    Background: Inferior alveolar nerve block is a common technique for anesthesia of the primary mandibular molars. A number of disadvantages have been shown to be associated with this technique. Periodontal ligament (PDL) injection could be considered as an alternative to inferior alveolar nerve block. The aim of this study was to evaluate the effectiveness of PDL injection in the anesthesia of primary molar pulpotomy with mandibular block. Methods: This study was performed using a sequential double-blind randomized trial design. 80 children aged 3-7 years old who required pulpotomy in symmetrical mandibular primary molars were selected. The teeth of these children were anesthetized with periodontal injection on one side of the mandible and block on the other. Pulpotomy was performed on each patient during the same appointment. Signs of discomfort, including hand and body tension and eye movement, the verbal complaint and crying (SEM scale), were evaluated by a dental assistant who was blinded to the treatment allocation of the patients. Finally, the data were analyzed using the exact Fisher test and Pearson Chi-squared exact test. Results: Success rate was 88/75 and 91/25 in the PDL injection and nerve block groups, respectively. There was no statistically significant difference between the two techniques (P = 0.250). Conclusion: Results showed that PDL injection can be used as an alternative to nerve block in pulpotomy of the mandibular primary molars. PMID:26028895

    This study's purpose was to assess clinical and radiographic outcomes of Copaifera langsdorffii oil resin (CLOR) as a pulpotomy medicament compared with one-minute full-strength formocresol (FC) and white mineral trioxide aggregate (WMTA). Determined by a power analysis, 152 primary molars of 64 four- to eight-year-olds with at least two asymptomatic molars requiring vital pulpotomies were recruited, randomly assigned to receive CLOR, WMTA, or FC, and restored with prefabricated metal crowns. At the 12-month follow-up, recordings of 59 children with 142 treated teeth were taken for clinical and radiographic symptoms. Clinical evaluation was performed by a blinded calibrated evaluator, whereas four evaluators scored each radiograph for pathologies based upon a modified scale previously proposed. The data were statistically analyzed. At 12 months, 100 percent clinical success was observed with all groups. CLOR had the highest frequency of pathologic radiolucencies at 12 months. The radiographic success at 12 months was 76 percent, 90.91 percent, and 88.23 percent for the CLOR, FC, and WMTA groups, respectively (P=0.10). Copaifera langsdorffii oil resin can be suggested as a pulpotomy agent for primary teeth up to one year. However, further clinical studies with long-term follow-ups are needed to test its efficacy as a pulpotomy medicament.

    Objective: The objective of this study was to compare the clinical and radiographic effects of Allium sativum oil and formocresol in nonvital pulpotomy in primary teeth. Materials and Methods: Twenty children ranging in age from 4 to 8 years were included in the study. In every one of those children, pulpotomy was indicated for the primary molars. Pulpotomy procedure was performed and the radicular pulp tissue of one molar was capped with A. sativum oil in a cotton pellet while the other molar was capped with formocresol. The teeth were evaluated clinically and radiographically before and after 6 months using standard clinical and radiographic criteria. Statistically, these results revealed significant difference between the radiographic findings of nonvital pulpotomy in primary molars with the two medicaments. Statistical analysis was performed using independent t-test and paired t-test at the significance level of α = 0.05. Results: A. sativum oil has potent antibacterial properties that enable it to combat intracanal microbes in the infected pulp of primary molars. Better results were obtained when A. sativum oil was used. Conclusion: A. sativum oil had more powerful effects than formocresol on the infected pulp of primary nonvital molars. PMID:26312232

    The aim of the study was to provide a comparative evaluation of the clinical and radiographic success of Ankaferd blood stopper (ABS), formocresol (FC), and ferric sulfate (FS) as pulpotomy agent in primary teeth. This is a clinical study. A total of 45 primary mandibular molar teeth in 26 children aged 6-9 were selected for the study. Teeth were randomly divided into three groups according to the pulpotomy agents (ABS, FC, FS). Following treatment, for 24 months, teeth were clinically and radiographically evaluated once every 3 and 6 months respectively. SPSS version 15 software was used in data analysis. Kaplan- Meier, Log Rank and Fisher's exact tests were used to analysis. After follow-up periods ranging from 6 to 24 months (average 20.8±0.56), the clinical success rates for ABS, FC, and FS were 87%, 87%, and 100% respectively. The overall radiographic success was 87%, 80%, and 87%. When success rates of the ABS were compared with other agents, there were no significant differences between groups (P > 0.05). Similar success was achieved in the pulpotomy treatment of primary teeth that using ABS, FC, and FS. ABS would be considered a suitable agent for pulpotomy treatment and can be used as an alternative to other agents.

    Mineral trioxide aggregate (MTA) used for pulpotomy procedures in immature permanent teeth can reduce treatment to 1 session as opposed to classic calcium hydroxide therapy, which necessitates multiple appointments. The main disadvantage of MTA use is crown discoloration after treatment. The aim of this study was to characterize 3 materials that are used for pulpotomy procedures in immature permanent teeth and assess their color stability in the presence of sodium hypochlorite solution. Hydrated Neo MTA Plus (Avalon Biomed Inc, Bradenton, FL), MTA Plus (Avalon Biomed Inc), and Biodentine (Septodont, Saint-Maur-des-Fossés, France) were characterized after immersion in Hank's balanced salt solution for 1 day and 28 days using a combination of scanning electron microscopy, energy-dispersive spectroscopy, and X-ray diffraction analysis. The color stability of the 3 materials in contact with water or sodium hypochlorite was evaluated by photography, spectrophotometry, and X-ray diffraction analysis. All the materials hydrated and produced calcium hydroxide as a by-product of hydration at early age. All materials interacted with synthetic tissue fluid, forming a calcium phosphate phase. MTA Plus exhibited discoloration in contact with sodium hypochlorite. All the materials tested are suitable to be used in the treatment of immature teeth because they all produced calcium hydroxide, which is necessary to induce dentin bridge formation and continued root formation. Neo MTA Plus and Biodentine are suitable alternatives to MTA, and they do not exhibit discoloration. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc.

    Full Text Available The aim of this case series was to determine the clinical and radiographic success rate of pulpotomy, with new endodontic cement (NEC, in human mature permanent molar teeth. Twelve molars with established irreversible pulpitis were selected from patients 14 - 62 years old. The selection criteria included carious pulp exposure with a positive history of lingering pain. After isolation, caries removal, and pulp exposure, pulpotomy with NEC was performed and a permanent restoration was immediately placed. At the first recall (+1 day no patients reported postoperative pain. One wisdom tooth had been extracted after two months because of failure in coronal restoration. Eleven patients were available for the second recall, with a mean time of 15.8 months. Clinical and radiographic examination revealed that all teeth were functional and free of signs and symptoms. Histological examination of the extracted teeth revealed complete dentin bridge formation and a normal pulp. Although the results favored the use of NEC, more studies with larger samples and a longer recall period were suggested, to justify the use of this novel material for treatment of irreversible pulpitis in human permanent molar teeth.

    Pulpotomy involves the removal of the coronal portion of pulp, including the diseased tissue, with the intent of maintaining the vitality of the remaining pulpal tissue via a therapeutic dressing. Once odontoblasts suffer injuries, the differentiation of mesenchymal cells is induced from the precursor cell population in the dental pulp, and these cells are recruited to the injured site to differentiate into odontoblasts. However, the involvement of immunocompetent cells during pulpal regeneration remains unclear. Thus, the purpose of this study was to investigate the properties of macrophages that infiltrated wound healing sites in rats between 1 and 28 days after pulpotomy (dap). During the inflammatory phase, ED1(+) (CD68(+) ) macrophages significantly increased throughout root pulp, especially apical to the demarcation zone, and this population persisted until 3 dap before decreasing gradually until 28 dap. OX6(+) macrophages expressing class II MHC also increased in the apical pulp at 1 dap and declined thereafter. However, OX6(+) cells appeared prior to dentin bridge formation at 3 dap and appeared again apical to the dentin bridge during the healing stage at 14 dap. The shift from ED1(+) cells in the inflammation phase to OX6(+) cells during dentin bridge formation might contribute to wound healing.

    Root canal therapy (RCT) and tooth extraction are the main treatment options for irreversible pulpitis or its sequelae. Pulpotomy is an alternative treatment; however, more evidence is required. If outcomes of pulpotomy with a calcium-enriched mixture (PCEM) are non-inferior for mature molars with irreversible pulpitis compared with those from one-visit RCT (ORCT), this may be a beneficial treatment option. Four hundred seven individuals met the inclusion criteria and were randomly allocated [PCEM (n = 205), ORCT (n = 202)]. We used NRS questionnaires to record pain intensity. Six-month clinical and radiographic successes were assessed. Individuals in the ORCT arm reported significantly more post-operative pain than those in the PCEM arm (P < 0.001). Clinical success rates in the two arms showed no statistically significant difference; however, the radiographic success rates were significantly greater in the PCEM arm (P < 0.001). This trial suggests PCEM as an alternative for treatment of irreversible pulpitis. If long-term results confirm initial ones, PCEM may revolutionize oral health worldwide.

    The aim of this study is to evaluate four different pulpotomy medicaments in primary molars. A total of 147 primary molars with deep caries were treated with four different pulpotomy medicaments (FC: formocresol, FS: ferric sulfate, CH: calcium hydroxide, and MTA: mineral trioxide aggregate) in this study. The criteria for tooth selection for inclusion were no clinical and radiographic evidence of pulp pathology. During 30 months of follow-up at 6-month intervals, clinical and radiographic success and failures were recorded. The differences between the groups were statistically analyzed using the Chi-square test and Kaplan-Meier analysis. At 30 months, clinical success rates were 100%, 95.2%, 96.4%, and 85% in the FC, FS, MTA, and CH groups, respectively. In radiographic analysis, the MTA group had the highest (96.4%), and the CH group had the lowest success rate (85%). There were no clinical and radiographic differences between materials (P > 0.05). Although there were no differences between materials, only in the CH group did three teeth require extraction due to further clinical symptoms of radiographic failures during the 30-month follow-up period. None of the failed teeth in the other groups required extraction during the 30-month follow-up period.

    To compare the clinical and radiographic response of primary teeth to vital pulpotomy using mineral trioxide aggregate (MTA) or formocresol (FC). A group of 17 children aged 4-9 were selected from those referred to the Paedodontic Department at Shahid Beheshti University, Dental School. Cases with at least two matching teeth were selected (40 teeth), showing signs of pulp involvement. A pulpotomy procedure was carried out in all cases with FC in control teeth whilst MTA was placed in experimental teeth. Clinical and radiographic evaluations were performed at 1-, 6-, 12- and 24-month recall. Statistical analysis using a Fischer exact test was performed on the data to determine significant differences between the groups. Overall, 22 second and 18 first primary molars were included. The gender ratio was one male to three female. No significant difference was found between the clinical and radiographic outcomes of the two groups at 6-, 12- and 24-month follow-up (P > 0.05). Internal resorption was seen significantly more often in FC cases after 12 months than MTA cases. Overall radiographic appearance of normal structures at 24th month was seen in more than 95% of the cases in MTA and 90% in the FC-treated group (P > 0.05). Mineral trioxide aggregate for pulp treatment of primary teeth can be considered a replacement for FC.

    The aim of this study was to compare the effect of white mineral trioxide aggregate (MTA) to that of formocresol (FC) as pulp dressing agents in pulpotomised primary molars. In this clinical trial study, 60 lower second primary molars of 46 children were treated by a conventional pulpotomy technique. The teeth were randomly assigned to the MTA (experimental) and FC (control) groups by random numbered table. Following removal of the coronal pulp and haemostasis, the pulp stumps were covered with an MTA paste in the experimental group. In the control group, FC was placed with a cotton pellet over the pulp stumps. The teeth of both groups were restored with stainless steel crowns. Children arrived for clinical and radiographic follow-up evaluation after 6, 12 and 24 months. The treated teeth in FC group (n = 18) were clinically and radiographically successful after 24 months. The radiographic follow-up evaluation revealed one failure (furcation involvement) in 18 molars treated with MTA after 24 months. The treated teeth in MTA group were clinically successful 24 months postoperatively. Pulp canal obliteration was observed in one of the teeth treated with MTA and four of the teeth treated with FC. MTA could be used as a safe medicament for pulpotomy in cariously exposed primary molars and could be a substitute for FC.

    Formocresol has been a popular pulpotomy medicament for many years. It is considered the "gold standard" in pediatric dentistry. However, concerns have been raised over its use in children. It has been reported that formocresol has toxic and mutagenic effects in cell culture, dental crypts, and precancerous epithelial cells. Therefore, additional biocompatible treatment alternatives are required to replace formocresol pulpotomy. This study compared the clinical and radiographic success rates of ferric sulfate (FS) and bioactive tricalcium silicate cement (Biodentine, Septodont) as pulpotomy agents in primary molar teeth over a period of 9 months. Fifty primary molar teeth, symptom free, requiring pulpotomy in children aged 4 to 8 years were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 25 teeth) and Biodentine (for 25 teeth) were used as pulpotomy agents. Permanent restorations were stainless steel crowns in most cases, in both groups. Patients were recalled for follow-up at 1, 3, 6, and 9 months intervals. The data were statistically analysed using chi-square test. At 9 months, 96% clinical success rate was observed in the FS and 100% in the Biodentine group. Radiographic success rate in the FS group was 84%, whereas 92% in the Biodentine group at 9 months. No statistically significant difference was found between the two groups. Biodentine can be used as a pulpotomy agent but further long-term studies are required. Sirohi K, Marwaha M, Gupta A, Bansal K, Srivastava A.

    Twenty human permanent teeth were used to study the pulpal response of two calcium hydroxide products, Dycal and Pulpdent Multi-Cal, after partial pulpotomy. Teeth were extracted at 4 months, fixed, and prepared for histologic examination. All 10 teeth treated with Dycal showed complete soft tissue healing and bridge formation. No stained bacteria were seen throughout the serial sections. One tooth treated with Dycal showed acceptable histologic results, dentin deposition in the root canal. Six cases dressed with Pulpdent Multi-Cal showed acceptable histologic results, whereas four teeth showed severe inflammation or necrosis associated with bacterial penetration into the pulp tissue. Clinically, one tooth treated with Pulpdent Multi-Cal showed pulpal pain and was extracted at 90 days. Our data support the thesis that human permanent pulps will promote tissue healing and dentin bridge formation as long as bacterial microleakage is excluded.

  18. Can miniature pulpotomy procedure improve treatment outcomes of direct pulp capping?

    2012-02-01

    Dental pulp exposure is a common incident during dental treatment. If there are clinical signs of pulp vitality, it is recommended to carry out direct pulp capping (DPC) using appropriate pulp covering agents (PCA). The main objectives are maintenance of pulp vitality/healing along with the formation of a calcified bridge beneath the PCA. Our proposed hypothesis is based on consideration of biologic principles in order to achieve improved treatment outcomes of DPC for cariously exposed pulp using miniature pulpotomy procedure (MPP). MPP will result in improved treatment outcomes of DPC by improved maintenance of a clean surgical pulp wound; removal of infected dentin chips/damaged pulp tissue specially injured odontoblast cells; improved proximity/interaction of PCA to undifferentiated mesenchymal/stem cells; better control of bleeding; and creating an improved seal using PCA.

It should also promote healing of the radicular pulp and prevent bacterial microleakage with the least interference in the physiological process of root resorption. Since the best criteria for judging the effectiveness of a medicament when used for vital pulp therapy is the response that it produces in the pulp. The purpose of the present study was to evaluate and compare the response of human pulp tissue to recently developed Indian material, Sree Chitra-Calcium Phosphate Cement (Chitra-CPC) and formocresol, used as pulpotomy agent in deciduous teeth. Chitra-CPC has been compared with formocresol, taking into account that formocresol is still considered the gold standard in primary tooth pulpotomy. The study was conducted among 10 children in the age group of 8 to 12 years focusing on 20 noncarious primary canines indicated for serial extraction. Each patient received two different pulpotomy procedures—one in each of the primary canines using formocresol and the other with Chitra-CPC as pulpotomy agents. After 70 days, the teeth were extracted and subjected to histological examination. The results did not reveal statistically significant difference between the two groups. But Chitra-CPC gave more favorable results, in respect of pulpal inflammation, dentin bridge formation, quality of dentin bridge and connective tissue in dentin bridge.

    Preventive measures have helped to minimize the occurrence of dental caries. However, premature loss of primary teeth on account of dental caries still remains a common problem among children. The pulpotomy technique has been the choice for treating vital primary and young permanent teeth with carious, mechanical and traumatic pulp exposures. The ideal pulpotomy medicament should be bioinductive or at least biocompatible, bactericidal and harmless to the pulp and surrounding structures.

    Introduction Vital pulp therapy is a major contributor in the preservation of primary dentition after caries affliction. Introduction of mineral trioxide aggregate (MTA) has revolutionized such treatment. Aim The aim of our study was to evaluate and correlate the effects of MTA clinically and radiographically on pulpotomized primary molars till their exfoliation or extraction followed by histological evaluation. Study design This is an observational study. Materials and methods A total of 25 teeth were selected from 5- to 8-year-old children requiring pulp therapy on the basis of inclusion and exclusion criterion. The teeth were treated by conventional pulpotomy technique under aseptic conditions using MTA and were immediately restored with stainless steel crown. The teeth were assessed postoperatively till 36 months. The exfoliated or extracted teeth were examined histologically. Results The pulpotomized teeth were vital with no adverse clinical findings during the observation period. After 3 months, one tooth showed internal resorption, but the same was not observed after 12 months. Pulp canal obliteration was seen in three cases. At the end of the study, five teeth were exfoliated and one tooth was extracted for maintaining arch symmetry. The histological examination of extracted tooth revealed the presence of healthy pulp and the area of true calcification. Remaining exfoliated teeth presented dentin bridge formation. Statistics Frequencies and percentages were used for descriptive statistics. Fisher’s exact tests were used to see the difference between clinical and radiological findings. The probability value was fixed at 5% level of significance. Conclusion The response of pulp in primary teeth to MTA was favorable in all cases from clinical and radiographic perspective, and histological evaluation confirmed the observation.

    To present a systematic review of the effects of formocresol and ferric sulphate when used as medicaments in pulpotomized primary molar teeth. The study list was obtained by using MEDLINE, the Cochrane Library, EMBASE and SCI search. Only those papers which met the inclusion criteria were accepted. The quality of studies used for meta-analysis was assessed by a series of validity criteria according to Jadad's scale. A systematic review and meta-analysis were performed. Eleven clinical studies comprising four randomized-clinical trials (RCTs), four controlled clinical trials (CCTs) and three retrospective studies were included. The results of the meta-analysis of six prospective clinical trials suggested that the two popular pulpotomy medicaments were not significantly different in terms of clinical outcomes, radiographic findings, prevalence of apical and furcal destruction, internal root resorption or pulp canal obliteration. The relative risk (RR) value and 95% CI for those parameters were 0.72 (0.43-1.23), 0.87 (0.59-1.30), 0.67 (0.27-1.66), 1.77 (0.56-5.58) and 1.41 (0.63-3.15), respectively. The overall clinical and radiographic success rates based on the data of treatments with ferric sulphate from the 11 studies included ranged from 78% to 100% (mean 91.6 +/- 8.15%) and from 42% to 97% (mean 73.5 +/- 18.40%), respectively. In primary molar teeth with exposure of vital pulps by caries or trauma, pulpotomies performed with either formocresol or ferric sulphate have similar clinical and radiographic success. Ferric sulphate may be recommended as a suitable replacement for formocresol.

    Full Text Available Purpose: The mutagenic potency of materials used in dentistry is of great concern. The Ames test is a bacterial reverse mutation assay, which is used to determine the mutagenicity potential of chemicals. In this study, the Ames test was used to compare mutagenic effects of three pulpotomy agents, namely, CEM cement, formocresol and ferric sulfate. Methods: TA100 strain of Salmonella typhimurium was used to evaluate mutagenicity of different concentrations of pulpotomy materials in the presence and absence of enzymatic system found in rat liver S9 fraction. Negative controls were 1% dimethyl sulfoxide and water. The positive controls were sodium azide and 2-aminoanthracene. The number of colonies per plate was counted. The material was regarded mutagenic if the number of histidine revertant colonies was twice or more than the spontaneous revertant colonies (Ames mutagenicity ratio. Results: Ferric sulfate was found mutagenic in the concentrations prepared by addition of 50 μL of its 1 in 100 and 1 in 1000 times diluted solutions to the culture medium in the absence of S9 fraction (Ames test ratios of 2.8 and 2.2, respectively. Formocresol showed strong toxicity toward TA100 strain of S. typhimurium up to the concentration as low achieved using 1000 times diluted solution of the original preparation, particularly in the presence of S9 fraction. Ames assay failed to detect significant reverse mutations in all the concentrations of CEM cement. Conclusion: In contrast to formocresol and ferric sulfate, CEM cement is a less toxic and non-mutagenic agent.

    Full Text Available "nCarious primary teeth are still a great problem in many countries. Maintaining these teeth, which play a significant role in chewing, guiding the permanent teeth to erupt normally and keeping the ideal dental arch size, is very important. The most common treatment of the deep carious primary teeth is pulpotomy. Many techniques and sub-base materials have been suggested for this purpose. "nAll traditional sub-base materials have been found to have different percentages of failure. Bonding systems are widely used in dentistry for tooth restoration. Their greatest advantage is providing better seal in the tooth-restoration interface, which is the primary goal in restorative dentistry.  The authors' suggestion is to use these materials as a sub-base agent subsequent to the electrosurgical pulpotomy technique. Bonding systems are easy to use, time efficient, biocompatible, do not need sealing pressure, and additionally provide an ideal seal.

    The aim of this study was to compare the biocompatibility of Endocem Zr(®) and ProRoot MTA(®) by histopathologic analysis in a canine model of pulpotomy. This study utilized 39 teeth of two beagle dogs. The exposed pulp tissues were treated by pulpotomy using ProRoot MTA (n=19) or Endocem Zr (n=20). After 8 weeks, the teeth were extracted and processed with hematoxylin-eosin staining for histologic evaluation. Most of the specimens in both groups developed a calcific barrier at the pulp amputation site and formed an odontoblast layer. However, some of the Endocem Zr specimens showed less calcific barrier formation with a greater inflammatory response and less odontoblast layer formation when compared with the ProRoot MTA specimens. ProRoot MTA and Endocem Zr specimens developed a calcific barrier; however, ProRoot MTA was more biocompatible than Endocem Zr.

    This prospective clinical study evaluated the success of vital pulpotomy treatment for permanent teeth with closed apices using mineral trioxide aggregates (MTA) in a dental public health setting. Twenty-seven mature permanent first molars and 2 premolars (in 25 patients) with carious exposure were treated using MTA pulpotomy. Age of patients ranged from 10- to 15-years (mean=13.2±1.74-years). Four trained and calibrated practitioners performed the same clinical procedure for all patients. Following isolation and caries removal, the inflamed pulp tissue was completely removed from the pulp chamber. This was followed by irrigation with 2% sodium hypochlorite. Haemostasis was achieved using a cotton pellet damped in normal saline. A white MTA paste was placed against the pulp orifices. MTA was covered with a damped cotton pellet and a base of IRM. Patients were recalled after 1 day where a glass ionomer liner and a final restoration were placed. Teeth were evaluated clinically and radiographically for up to 47 months. Mean follow-up period for all teeth was 25±14 months. Twenty-six of the 29 teeth were clinically asymptomatic with no evidence of periradicular or root pathology during the follow-up period. The estimated success rate was 90%. Three teeth presented with clinical symptoms of pain and radiographic evidence of periradicular pathology that indicated root canal treatment (RCT) or extraction. When managing carious pulp exposures of permanent teeth with closed root apices in children, MTA pulpotomy showed a high success rate. MTA pulpotomy for permanent molars in children is a viable alternative to RCT. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Methods of systematic review and meta analysis were employed to compare the success rate of pulpotomy of primary molars using mineral trioxide aggregate (MTA) and ferric sulfate (FS) as two regenerative and preservative agents, respectively. After raising a PICO question (In pulpotomy of vital carious-exposed primary molars, how does MTA compare to FS in terms of clinical and radiographic outcomes?) and determining the search strategy, MeSH-matching keywords were searched in four electronic databases and retrieved papers were examined in titles, and if necessary abstracts and full texts, to be relevant. Randomized clinical trials (RCTs) evaluating pulpotomy of vital primary molars after carious/traumatic exposure conducted with either FS or MTA, with at least a 6-month recall, tooth restorability, and those considering clinical and radiographic signs/symptoms, were included. The nonrandomized allocation and absence of comparison between the treatment groups caused the exclusion of the article. The quality of the RCTs and also their risk of bias (low, moderate, high), were assessed using a modification of van Tulder list; for meta-analysis of the matching studies, the extracted data were analyzed by Mantel Hanszel analysis. A total number of 620 articles were found. After exclusion of the common titles and application of the eligibility criteria, 4 RCTs [12-month follow-up: n=3, 24-month follow-up: n=4, in total: 264 teeth) comparing MTA and FS, were selected. It was showed that the 12-month outcome of both materials were similar [RR= 0.642 (CI 95%: 0.225-1.833, P=0.407)], while the two-year follow-up results revealed significant differences in treatment outcome, in favor of MTA [RR was 0.300 (CI 95%: 0.132-0.683, P=0.004)]. MTA demonstrated superior long-term treatment outcomes in pulpotomy of primary molars than FS.

    Bioactive glass (BAG) is often used as a filler material for repair of dental bone defects. Although there is evidence of osteogenic potential of this material, it is not clear yet whether the material exhibits potential for dentinogenesis. Hence, the aim of the present study was to evaluate BAG as a pulpotomy agent and to compare it with three commercially available pulpotomy agents such as formocresol (FC), ferric sulfate (FS), and mineral trioxide aggregate (MTA). Pulpotomies were performed in 80 maxillary first molars of Sprague Dawley rats, and pulp stumps were covered with BAG, FC, FS, and MTA. Histologic analysis was performed at 2 weeks and then at 4 weeks after treatment. Experimental samples were compared with contra-lateral normal maxillary first molars. At 2 weeks, BAG showed inflammatory changes in the pulp. After 4 weeks, some samples showed normal pulp histology, with evidence of vasodilation. At 2 weeks, MTA samples showed some acute inflammatory cells around the material with evidence of macrophages in the radicular pulp. Dentine bridge formation with normal pulp histology was a consistent finding at 2 and 4 weeks with MTA. Ferric sulfate showed moderate inflammation of pulp with widespread necrosis in coronal pulp at 2 and 4 weeks. Formocresol showed zones of atrophy, inflammation, and fibrosis. Fibrosis was more extensive at 4 weeks with evidence of calcification in certain samples. Among the materials tested, MTA performed ideally as a pulpotomy agent causing dentine bridge formation while simultaneously maintaining normal pulpal histology. It appeared that BAG induced an inflammatory response at 2 weeks with resolution of inflammation at 4 weeks.

    Pulpal necrosis of an immature permanent tooth with an open apex poses a challenge for the clinician. The conventional apexification technique using calcium hydroxide has yielded short-term success, but this technique has inevitable shortcomings. Hence, this case series aimed to evaluate the effectiveness of using bioceramics (iRoot BP) or mineral trioxide aggregate (MTA) for partial pulpotomies. Three boys aged 9 to 11 years old presented with partial pulp necrosis and symptomatic apical periodontitis of the mandibular right and left second premolar. The involved teeth were treated with a partial pulpotomy using either iRoot BP (case 1 and 2) or MTA (case 3). At the 8-month follow-up, no abnormal clinical signs or symptoms were observed. Periapical radiographs revealed a significant reduction in periapical radiolucency, a marked increase in the root canal wall thickness and ongoing closure of the apical opening. The bioceramic material (iRoot BP) and MTA both produced successful outcomes in the partial pulpotomy of immature teeth with partial pulp necrosis and apical periodontitis. However, iRoot BP was superior in terms of ease of clinical application, and would therefore be a better treatment alternative than MTA.

    Full Text Available Aim: This study aimed to evaluate and compare the Platelet-rich fibrin (PRF and Mineral trioxide aggregate (MTA as a pulpotomy agent in primary molars. Material and Methods: In this study, 50 primary molars from 50 healthy children aged 5–9 years requiring pulpotomy were randomly allocated into two groups. In PRF group, after coronal pulp removal and hemostasis, remaining pulp tissue was covered with PRF preparation. In the MTA group, the pulp stumps were covered with MTA (Pro Root MTA-Root Canal Repair Material, Dentsply International Inc. paste obtained by mixing MTA powder with sterile water at a 3:1 powder to water ratio. All teeth were restored with reinforced zinc oxide eugenol base and glass – ionomer cement. Stainless steel crowns were given in both groups 24 h after treatment. Clinical evaluation was undertaken at 1, 3, and 6 months intervals whereas radiographic evaluation of the treated teeth was carried out at the interval of 6 months. Results: By the end of 6 months, the overall success rate was 90% in PRF group and 92% in MTA Group. A statistically significant difference was observed between the groups at 6 months of follow-up (P 0.05. Conclusion: Radiographic and clinical outcome in PRF group could suggest it as an acceptable alternative in pulpotomy of primary teeth. PRF holds a promising future in the area of primary tooth vital pulp therapy.

      To discuss the clinical and radiographic success of a pulpotomy with second-generation platelet concentrate (PRF), in a human mature permanent molar tooth.   A 19-year-old female patient reported to the Department of Conservative Dentistry and Endodontics with established pulpitis in tooth 36. The tooth had a carious pulp exposure, with a history of lingering pain. After isolation, caries removal and pulp exposure, pulpotomy with PRF was performed and a permanent restoration was placed immediately. At the first recall (+1 day), no postoperative pain was reported. At 6, 12, 18 and 22 months recall, the tooth responded positively to pulp sensibility tests, and radiographic examination revealed a normal periodontal ligament space. Positive results of this case imply the need for more studies with larger sample sizes and a longer recall period to justify the use of this novel material for the treatment of pulpitis in human permanent molar teeth. Pulpotomy with PRF could be an alternate treatment to mineral trioxide aggregate or other materials in mature permanent teeth with pulpitis. © 2011 International Endodontic Journal.

    Full Text Available Introduction: Recently, some studies have compared mineral trioxide aggregate (MTA with portland cement (PC, concluding that the principle ingredients of PC are similar to those of MTA. The purpose of the present study was to evaluate the biocompatibility of PC as a pulpotomy medicament. Materials and Methods: Thirty premolars that scheduled for extraction for therapeutic reasons were randomly assigned to two experimental groups: ProRoot MTA (PMTA and PC. After isolation and pulp exposure, pulpotomy was carried out and pulps were dressed with PMTA and PC. After 6 months, the teeth were extracted and prepared for histological analysis based on Cox et al. criteria. The data were analyzed by Z-test of proportion with 1% of allowed error. Results: No statistically significant difference was found between the two groups with respect to inflammatory response, soft tissue organization, and dentine bridge formation (P > 0.05. Conclusions: PC was associated with similar favorable biological response to pulpotomy treatment as PMTA. The findings of this study support the idea that PC can be considered a cheaper substitute to MTA.

    Full Text Available Objective: Several studies have compared ferric sulfate and formocresol pulpotomy in primary molars. The results of these studies, however, could not be compared due to differencesin evaluated outcomes (clinical, radiographic, or histologic and follow up duration.The aim of the present study was a systematic review of similar studies and a metaanalysis of their results to provide the latest evidence on the issue.Materials and Methods: Web-based search was done in EMBASE,Cochrane, Pubmed,Google Scholar, IranMedex, Scientific Citation Index (SCI, and Scopus index databases.A hand search also was conducted in scientific and research dental journals approved by the Ministry of Health and Medical Education of Iran. Eight randomized clinical trial articles were selected. Clinical success, clinical and radiographic success (total success rate were assessed as outcome variables. Peto test served for data analysis.Results: The clinical success of formocresol pulpotomy was comparable to that of ferric sulfate (P=0.574. In addition, the difference between total success rate of the two methods in different studies was insignificant (P=0.42.Conclusion: No significant difference existed between the total success rate of formocresol and ferric sulfate pulpotomy, and ferric sulfate can be an appropriate alternative for formocresol.

    This study systematically reviewed randomized clinical trials (RCTs) investigating the effectiveness of primary molar pulpotomies with mineral trioxide aggregate (MTA) and formocresol. The study also aimed to assess the possible association of reported prognostic factors on the success rate and relative risk using meta-regression analysis. A comprehensive literature search using Medline, EMBASE, and Cochrane Central databases up to March 2013 was conducted. After scoring and data extraction of qualified trials (n = 19, representing 1,585 patients), meta-analyses were performed using Mantel-Haenszel model and inverse variance-weighted method. The results revealed that MTA is more effective than formocresol in primary molars pulpotomy, resulting in a lower failure rate with a relative risk of 0.26 (CI, 0.13-0.49), 0.37 (CI, 0.19-0.70), and 0.41 (CI, 0.25-0.68) for 6-, 12-, and 24-month follow-ups (test for statistical heterogeneity: p = 0.99, p = 0.98, and p = 0.23), respectively. Compared to amalgam restoration, success rate was significantly greater with SS crown (P formocresol. When compared with formocresol, MTA pulpotomy is superior in treating primary molars.

    Full Text Available In traumatized, young, permanent teeth, pulpotomy is classically undertaken to promote apexogenesis. The objective is to promote root development and apical closure. Once root end development and apical closure is achieved, the root canal treatment is completed. However, it has been suggested that mere pulp exposure does not cause pulpitis in the absence of bacteria. Recent studies have proposed that as long as a good seal is ensured, root canal treatment may not be necessary following pulpotomy.In this article we report two cases of traumatized, fully matured, maxillary permanent central incisors, which have been treated with mineral trioxide aggregate following partial pulpotomy, with a two-year follow-up.

    Studies have suggested that formocresol has toxic and carcinogenic potential. A search for an alternative medicament for primary tooth pulpotomies has led to ferric sulfate as a possible alternative. A retrospective study was done in a multipractitioner IHS (Indian Health Service) clinic. Radiographic success or failure was determined for 202 primary tooth pulpotomies performed with either formocresol, ferric sulfate, or a combination procedure of formocresol and ferric sulfate. The post-operative period for the pulpotomies ranged from one month to thirty-six plus months. There was no statistical difference in radiographic failure rates between formocresol, ferric sulfate, or the combination procedure when results were analyzed regardless of post-op period. However, when post-op periods were considered, formocresol performed better at > 36 months and the combination procedure showed significantly more failures at > 36 months.

    Human dental pulp inflammation can progress to periapical lesion formation and conventional root canal treatment (RCT) has been the traditional method for disease management. This observational study presents two cases of vital pulp therapy in mature molars diagnosed with irreversible pulpitis and associated with apical periodontitis. In these two clinical cases, the involved teeth had deep carious lesions with a history of spontaneous/lingering pain and radiographic examinations revealed the presence of apical radiolucencies. A conservative miniature pulpotomy (MP) using calcium-enriched mixture (CEM) was performed and the teeth were permanently restored with amalgam. Clinical evaluations indicated resolution of pain 24 hours after treatment; the teeth showed normal vitality, remained asymptomatic and maintained normal function after recall examinations. Furthermore, the 18-month radiographic evaluation showed healing of the apical lesions. Vital pulp therapy using the MP technique with CEM appeared successful in avoiding RCT intervention. These two reports of case outcome suggest that simple MP using a CEM bioregenerative technique may provide a favorable outcome for permanent teeth diagnosed with irreversible pulpitis and associated with apical periodontitis.

    To assess dental practice regarding the use of indirect pulp capping or pulpotomy in children with deep carious lesions approaching the pulp in primary teeth and to compare the efficacy of the two pulp treatments. Systematic review. We searched the Cochrane Library, PubMed via MEDLINE, and EMBASE as well as the reference lists of included reports and ClinicalTrials.gov (for ongoing trials). Eligible studies were surveys of dental practice sent to dentists regarding the use of indirect pulp capping and pulpotomy in children with deep carious lesions approaching the pulp in primary teeth and any type of clinical study. Two review authors independently extracted data and assessed risk of bias in duplicate. Of the 481 potentially eligible articles, 11 were included in the review: 8 described surveys of dental practice, 1 a non-randomised study, and 2 ongoing randomised trials. The surveys of dental practice showed an overall increase in the teaching and practice of indirect pulp capping in primary teeth. The non- randomised study found a statistically significant difference in favour of indirect pulp capping for clinical and radiological success at 3 years but with high overall risk of bias. Despite the success rate of indirect pulp capping for treating deep carious lesions approaching the pulp in primary teeth, practitioners still hesitate to practice this technique because of lack of evidence and studies on this topic. Thus, for strong evidence, investigators are encouraged to conduct randomised trials comparing the efficacy of indirect pulp capping and pulpotomy for treating deep carious lesions approaching the pulp in primary teeth.

    Introduction Pulpotomy technique basically consists of removing the coronal pulp and fixing the radicular pulp with a medicament. It is the most widely accepted clinical procedure for treating primary teeth with coronal pulp inflammation caused by caries with no involvement of the radicular pulp. Aim To evaluate the success and efficacy of Mineral Trioxide Aggregate (MTA), Lasers and Biodentine as pulpotomy agents both clinically and radiographically. Materials and Methods In the present study, 60 primary molars in children whose pulpal status warranted pulpotomy were selected and randomly assigned into three groups that included MTA, Laser and Biodentine allocating 20 teeth to each group. The pulpotomy procedure was then performed on all selected teeth followed by restoration with stainless steel crowns. Later the patients were recalled for 3 months and 6 months for clinical and radiographic evaluation. Results Statistical analysis was done using Fisher exact test to determine pair wise comparison of three agents with respect to clinical and radiographic criteria. Kruskal-Wallis ANOVA, Mc Nemars test was applied to evaluate the efficacy of each agent between 3 months and 6 months. The results showed that maximum success rate was found in MTA group. However, the comparison between three groups was statistically not significant (pFormocresol. PMID:26023640

    Background: Pulpotomy has been proposed as an alternative for the management of irreversible pulpitis in permanent molars with closed apices. Aim: To compare the performances of calcium hydroxide (CH), mineral trioxide aggregate (MTA), and platelet-rich fibrin (PRF) as pulpotomy agents in mature permanent molars with irreversible pulpitis. Materials and Methods: Fifty-four permanent mandibular molars with carious exposure and symptoms of irreversible pulpitis were randomly allocated to three groups, and full pulpotomy was performed using CH, MTA, or PRF as pulpotomy agents. Pain intensity was recorded using numeric rating scale score at baseline, 24 h, 7 days, 6 months, and 1 year. Clinical and radiographic assessments were done at 6 months and 1 year. Statistical Analysis: Kruskal–Wallis test and Friedman test were used for intergroup and intragroup comparison of pain scores, respectively. The radiographic outcomes between the three study arms were compared using Chi-square test. Results: Clinical success rate was 94.4% at 7 days, which dropped to 85.4% at 12 months. All three agents were equally effective in providing pain relief at all the intervals tested, with no significant difference between them (P > 0.05 at all intervals). However, at 6 months and 12 months, 26.2% and 52.4% teeth depicted slight widening of periodontal ligament space. No significant difference was observed between the radiographic success rates observed with the three groups (P = 0.135 at 6 months, 0.717 at 12 months). Conclusion: Pulpotomy exhibited a high clinical success rate in mature molars with irreversible pulpitis and selection of biomaterial did not affect its outcome. PMID:27994420

    Autotransplantation is the surgical transposition of a tooth from its original site to another, replacing a lost or a compromised tooth by another tooth, usually the third molar in the same individual. This technique is considered a viable method due to its high success rate, well-grounded treatment option, provided the case selection and the procedure followed is within the acceptable limits. Autotransplantation is considered as an alternative approach of oral rehabilitations in a conservative manner mainly in young patients with compromised financial conditions to perform a high cost treatment. It is a fast way to recover function and aesthetic properties without interfering with the orofacial growth. This report describes a successful 4-year follow-up of a case of immediately performed mineral trioxide aggregate (MTA) pulpotomy in autotransplantated mandibular left immature third molar to replace the mandibular left first molar that was extracted due to extensive carious lesion.

    This study evaluated the pulpal and periapical responses of dogs' teeth after pulpotomy and pulp capping with a new tricalcium silicate-based cement (Biodentine) when compared with mineral trioxide aggregate (MTA) by radiographic, histopathologic, and histomicrobiological analyses. Sixty roots (30 teeth) of dogs were divided into 2 groups, Biodentine (n = 36 roots) and ProRoot MTA (control, n = 24 roots). Animals were killed after 120 days, and the teeth were subjected to histotechnical processing (hematoxylin-eosin and Brown and Brenn staining). Qualitative and quantitative histopathologic data were analyzed by Fisher exact and Mann-Whitney tests (α = 0.05). Radiographically, mineralized tissue bridge formation was observed in more specimens treated with Biodentine (96.8%) than with MTA (72.2%) (P = .02). Integrity of the lamina dura and absence of periapical bone rarefaction and root resorption (external and internal) were observed in all specimens. Histopathologic and histomicrobiological analyses revealed mineralized tissue bridge formation, pulpal vitality, odontoblast layer integrity, preserved periodontal ligament, and absence of bone or root resorption and microorganisms in both groups. Although the bridges formed at the amputation site had similar morphology, they were significantly thicker in the Biodentine group (P Biodentine group was related to bridge thickness because radiographic diagnosis was flawed for bridges with thickness less than 0.5 mm. Fluorescence microscopy improved the visualization of bridge structure. Biodentine presented tissue compatibility and allowed for mineralized tissue bridge formation after pulpotomy in all specimens with similar morphology and integrity to those formed with use of MTA. Periapical radiographs failed in detecting mineralized tissue bridges with thickness less than 0.5 mm. Copyright © 2014 American Association of Endodontists. Published by Elsevier Inc.

    Questions exist regarding the efficacy of resin-containing materials such as TheraCal directly applied on the pulp. This study sought to investigate the clinical efficacy of TheraCal as compared with Biodentine and ProRoot mineral trioxide aggregate (MTA) for partial pulpotomy. In this clinical trial, partial pulpotomy was performed for 27 sound human maxillary and mandibular third molars scheduled for extraction. The teeth were randomly divided into 3 groups (n = 9) and underwent partial pulpotomy with TheraCal, Biodentine, and ProRoot MTA. The teeth were then restored with glass ionomer cement. Clinical and electric pulp tests were performed after 1 and 8 weeks. The teeth were radiographed and extracted at 8 weeks. Histologic sections were prepared and analyzed for pulp inflammation and dentinal bridge formation. Data were analyzed by using one-way analysis of variance. Clinical examination showed no sensitivity to heat, cold, or palpation in ProRoot MTA and Biodentine groups. Two patients in TheraCal group (20%) reported significant pain at 1 week. Periapical radiographs showed no periapical pathology, and electric pulp test revealed a normal pulp response with no hypersensitivity. Inflammation was absent with all materials at 8 weeks. Normal pulp organization was seen in 33.33% of the teeth in ProRoot MTA, 11.11% in TheraCal, and 66.67% in Biodentine group (P = .06). Biodentine group showed complete dentinal bridge formation in all teeth, whereas this rate was 11% and 56% in TheraCal and ProRoot MTA groups, respectively (P = .001). Overall, Biodentine and MTA performed better than TheraCal when used as partial pulpotomy agent and presented the best clinical outcomes. Copyright © 2017 American Association of Endodontists.

    In traumatized, young, permanent teeth, pulpotomy is classically undertaken to promote apexogenesis. The objective is to promote root development and apical closure. Once root end development and apical closure is achieved, the root canal treatment is completed. However, it has been suggested that mere pulp exposure does not cause pulpitis in the absence of bacteria. Recent studies have proposed that as long as a good seal is ensured, root canal treatment may not be necessary following pulpot...

    The aim of this study was to evaluate and to compare clinical and radiographic outcomes of 4 materials (formocresol, mineral trioxide aggregate (MTA), Portland cement and enamel matrix derivative) using in primary teeth pulpotomies. Sixty-five patients aged 5-9 years (32 female, 33 male) were included in this study. A total of 140 primary first and second molars with deep caries were treated with pulpotomy. All teeth were then restored with stainless steel crowns. The treated teeth were evaluated clinically and radiographically at 3, 6, 12, 18 and 24 months. At 24 months, the clinical success rates of formocresol, MTA, Portland cement, and enamel matrix derivative were 96.9%, 100%, 93.9%, and 93.3%, respectively. The corresponding radiographic success rates were 84.4%, 93.9%, 86.7% and 78.1%, respectively. Although there were no statistically significant differences in clinical and radiographic success rates among the 4 groups, MTA appears to be superior to formocresol, Portland cement, and enamel matrix derivative as a pulpotomy agent in primary teeth.

    The aim of this study was to compare the responses of mineral trioxide aggregate (MTA) and combined MTA/treated dentin matrix (TDM) as direct pulp capping material. In this clinical trial study, 33 intact third molars in 11 healthy volunteers (three molars in each) were included. Partial pulpotomies were performed in a split mouth manner in two of the third molars in each patient randomly and the third tooth had used as TDM source. The coronal dentin was chopped to dentine chips and transformed to TDM using different concentrations of ethylene diamine tetraacetic acid (EDTA) solution. Pulps were directly capped by MTA alone or using a combination layering of MTA/TDM. Following 6-week clinical and radiological evaluations, each tooth was extracted and prepared for histological evaluation. There were no significant differences in the clinical and radiographic responses or in the quality of dentin bridges (P > 0.05). However, the dentin bridge was significantly thicker in MTA/TDM group than MTA group (P = 0.003). Using the combination of MTA/TDM as a pulp-dressing agent may form a thicker dentin bridge compared to MTA alone. © 2017 Australian Society of Endodontology Inc.

    The objective of this research was to evaluate the response of Portland cement associated with different radio pacifying agents on pulp treatment of human primary teeth by clinical and radiographic exams and microscopic analysis. Thirty mandibular primary molars were randomly divided into the following groups: Group I - Portland cement; Group II - Portland cement with iodoform (Portland cement + CHI3 ); Group III - Portland cement with zirconium oxide (Portland cement + ZrO2 ); and treated by pulpotomy technique (removal of a portion of the pulp aiming to maintain the vitally of the remaining radicular pulp tissue using a therapeutic dressing). Clinical and radiographic evaluations were recorded at 6, 12 and 24 months follow-up. The teeth at the regular exfoliation period were extracted and processed for histological analysis. Data were tested using statistical analysis with a significance level of 5%. The microscopic findings were descriptively analysed. All treated teeth were clinically and radiographically successful at follow-up appointments. The microscopic analysis revealed positive response to pulp repair with hard tissue barrier formation and pulp calcification in the remaining roots of all available teeth. The findings of this study suggest that primary teeth pulp tissue exhibited satisfactory biological response to Portland cement associated with radio pacifying agents. However, further studies with long-term follow-up are needed to determine the safe clinical indication of this alternative material for pulp therapy of primary teeth.

    To compare the clinical and radiographic success rates of three different pulpotomy agents in primary molars after 18 months. The study was carried out with 51 primary molars of children aged 5-9 years old. The teeth were randomly assigned to the experimental or control groups. After coronal pulp removal and haemostasis, the remaining pulp tissue was covered with Biodentine(®) or mineral trioxide aggregate in the experimental groups. In the control group, formocresol was placed with a cotton pellet over the pulp tissue for 5 min and after removal the pulp tissue was covered with zinc oxide-eugenol (ZOE) paste. All teeth were immediately restored with reinforced ZOE base and resin modified glass-ionomer cement, and later with pre-formed metal crowns. Follow-up assessments were carried out after 3, 6, 12 and 18 months. Forty-five teeth were available for follow up at the end of 18 months. All of the available teeth for mineral trioxide aggregate and Biodentine(®) were clinically successful, as were 73.3% of the FC group. Radiographic success rate for the formocresol group at 18 months follow up was 73.3, 100% for mineral trioxide aggregate and 86.6% for Biodentine(®) group. Mineral Trioxide aggregate and Biodentine(®) showed more favourable results than formocresol.

    The authors conducted a systematic review and meta-analysis to compare the long-term clinical and radiographic success of using mineral trioxide aggregate (MTA) and formocresol (FC) as a pulp-dressing material in pulpotomy treatment in primary molars. The authors searched MEDLINE, Thomson Reuters Web of Science and the Cochrane Central Register of Controlled Trials for randomized controlled trials (RCTs) published from Jan. 1, 1990, to May 9, 2013. For an RCT to be included, the authors required that the primary molars treated with a pulpotomy procedure must have received stainless steel crowns as a final restoration and that rubber dam isolation was used during treatment; that the pulp must have been vital as determined clinically by means of hemorrhage control with a cotton pellet; and that the RCT must have included a follow-up period of at least two years. For each included RCT, two authors assessed the risk of bias independently. The authors identified 20 trials and included five of them. A total of 377 primary molars were treated. The authors judged that none of the included RCTs had a low risk of bias. They noted no significant differences in clinical success (relative risk [RR] = 1.01; 95 percent confidence interval [CI], 0.98-1.05) and radiographic success (RR = 1.09; 95 percent CI, 0.97-1.21) for primary molars treated with MTA versus those treated with FC. On the basis of the limited evidence, pulpotomy procedures performed in primary molars involving the use of MTA or FC showed comparable clinical success rates.

    Full Text Available Aim. (1 The aim of the clinical study revolves around the accurate diagnosis, proper case selection, and the management of acute irreversible pulpitis in permanent molars with closed apices using conservative and economical treatment modalities like vital pulpotomies with regenerative approaches over conventional root canal procedures. (2 To evaluate the use of autologous substances such as platelet concentrates and calcium silicate based materials in promoting the healing and regeneration of the inflamed pulp. Summary. Vital pulpotomy was performed on 5 carious involved, permanent molars diagnosed with acute irreversible pulpitis in 17- to 22-year-old patients. Taking into consideration the patient’s age and the condition of the underlying pulp tissue, PRF pulpotomy was planned in view of preserving the vitality of the intact radicular pulps. Regenerative procedures with second generation blood matrices were chosen to encourage the recovery of the inflamed pulps. The systematic follow-up examinations performed at 3, 6, 9, 12, 18, 22, and 24 months revealed a successful clinical and radiological outcome. Within the limits of the present clinical study and correlating the success across the treated clinical cases, we safely conclude the potential scope of regenerative pulpotomy approaches in acute irreversible pulpitis in adult permanent teeth.

    The purpose of this study was to evaluate and compare the effects of formocresol (FC), ferric sulfate (FS), white mineral trioxide aggregate (WMTA), white Portland cement (WPC), and beta-tricalcium phosphate (beta-TCP) on pulpotomized primary teeth of pigs. Fifty teeth of three 3-month old pigs were pulpotomized with these materials. Three weeks later, the animals were euthanized and the specimens were prepared for histological examination. There was no significant difference between beta-TCP, WMTA, and WPC in terms of primary pulp response, hard tissue formation, and normal pulp tissue preservation. But, both FS and FC irritated the pulp tissue, provoking a more inflammatory pulp response than beta-TCP, WMTA, and WPC. Beta-TCP, WMTA, and WPC are histologically more effective pulpotomy agents than formocresol and ferric sulfate in primary pig teeth.

    This study was conducted to evaluate and compare pulpal responses to ProRoot MTA (Dentsply Tulsa Dental, Tulsa, OK), RetroMTA (Meta Biomed Co, Ltd, Seoul, Korea), and TheraCal (Bisco Inc, Schamburg, IL) in dog partial pulpotomy models. Partial pulpotomies were performed on 60 beagle teeth. The exposed pulp tissues were randomly capped with either ProRoot MTA (n = 15), RetroMTA (n = 15), TheraCal (n = 15), or interim restorative material as a negative control (n = 15). After 4 weeks, the teeth were extracted and processed for histologic and immunohistochemical examinations using osteocalcin and dentin sialoprotein. Calcific barrier formation, inflammatory reaction, and the odontoblastic layer were evaluated and scored in a blind manner. The areas of newly formed calcific barriers were measured for each group. In most of the ProRoot MTA and RetroMTA specimens, continuous calcific barriers were formed, and the pulps contained palisading patterns in the odontoblastic layer that were free of inflammation. However, the TheraCal specimens had lower quality calcific barrier formation, extensive inflammation, and less favorable odontoblastic layer formation. Overall, areas of newly formed calcific barrier were higher in the ProRoot MTA and RetroMTA specimens than in the TheraCal specimens. Also, immunohistochemistry revealed that osteocalcin and dentin sialoprotein were more clearly visible in the ProRoot MTA and RetroMTA specimens than in the TheraCal specimens. RetroMTA could provide an alternative to ProRoot MTA. Both materials produced favorable pulpal responses that were similar in nature, whereas TheraCal produced less favorable pulpal responses.

    Objective:To investigate the clinical characteristics and prognosis of pulpotomy with Pulp-dent Multi-Cal (PMC) in young permanent incisors. Methods: Twenty-five young permanet incisors with vital pulps and complicated crown fractures were treated by pulpotomy with PMC at the Emergency Department of Peking University School and Hospital of Stomatology. The teeth were checked clinically and radiographically during fixed intervals. Healing of the pulp was considered to have taken place if the following criteria were met; absence of clinical symptoms, absence of apical radiolucency, continued root development in immature teeth, radiographic evidence of dentin bridge formation, and positive response to pulp vitality tests. The results were compared with the teeth which underwent pulpotomy with preparation made by our hospital. Results:Followed up for 6 -15 months (median 12 months) , on basis of the criteria for pulp healing, all teeth got successful treatment. And all the teeth showed radiographic evidence of dentin bridge formation within 1 to 3 months after pulpotomy. The operation time of PMC pulpotomy was significantly shortened (P <0.01). The root length of teeth performed with PMC pulpotomy and normal teeth had no significant difference (P >0. 05). Conclusion: PMC is an acceptable material when used in pulpotomy of young permanent teeth.%目的:研究Pulpdent Multi-Cal (PMC)盖髓剂用于活髓切断术的临床可操作性和疗效,为临床应用提供参考依据.方法:对因冠折露髓到北京大学口腔医院急诊科就诊患者的上颌年轻恒前牙25颗(20例患者)进行活髓切断术,用PMC盖髓剂作为活髓保存剂,观察临床可操作性和操作时间,术后对患牙进行定期随访观察,复诊时记录患牙的临床检查和X线片检查情况,并与采用北京大学口腔医院自制制剂进行活髓切断术的患牙进行比较.结果:随访6~15个月(中位时间12个月),25颗患牙(20例患者)均于1~3个月间

    Less invasive excavation methods have been suggested for deep caries lesions. We tested the effects of stepwise vs. direct complete excavation, 1 yr after the procedure had been carried out, in 314 adults (from six centres) who had received treatment of a tooth with deep caries. The teeth had caries lesions involving 75% or more of the dentin and were centrally randomized to stepwise or direct complete excavation. Stepwise excavation resulted in fewer pulp exposures compared with direct complete excavation [difference: 11.4%, 95% confidence interval (CI) (1.2; 21.3)]. At 1 yr of follow-up, there was a statistically significantly higher success rate with stepwise excavation, with success being defined as an unexposed pulp with sustained pulp vitality without apical radiolucency [difference: 11.7%, 95% CI (0.5; 22.5)]. In a subsequent nested trial, 58 patients with exposed pulps were randomized to direct capping or partial pulpotomy. We found no significant difference in pulp vitality without apical radiolucency between the two capping procedures after more than 1 yr [31.8% and 34.5%; difference: 2.7%, 95% CI (-22.7; 26.6)]. In conclusion, stepwise excavation decreases the risk of pulp exposure compared with direct complete excavation. In view of the poor prognosis of vital pulp treatment, a stepwise excavation approach for managing deep caries lesions is recommended.

    Introduction: The aim of this randomized clinical trial was to compare the histologic pulp tissue response to one-step direct pulp capping (DPC) and miniature pulpotomy (MP) with mineral trioxide aggregate (MTA) after application of dexamethasone in healthy human premolars. Methods and Materials: Forty intact premolars from 10 orthodontic patients, were randomly chosen for DPC (n=20) or MP (n=20). In 10 teeth from each group, after exposure of the buccal pulp horn, topical dexamethasone was applied over the pulp. In all teeth the exposed/miniaturely resected pulp tissue was covered with MTA and cavities were restored with glass ionomer. Teeth vitality was evaluated during the next 7, 21, 42, and 60 days. Signs and/or symptoms of irreversible pulpitis or pulp necrosis were considered as failure. According to the orthodontic schedule, after 60 days the teeth were extracted and submitted for histological examination. The Kruskal-Wallis and Fisher’s exact tests were used for statistical analysis of the data (P=0.05). Results: Although dexamethasone specimens showed less inflammation, calcified bridge, pulpal blood vasculature, collagen fibers and granulation tissue formation were not significantly different between the groups (P>0.05). Conclusion: Topical dexamethasone did not hindered pulp healing but reduced the amount of underlying pulpal tissue inflammation after DPC and MP in healthy human premolars. PMID:27141213

    Full Text Available The aim of this study was to evaluate the clinical status of pulpotomy treatment with calcium hydroxide and to correlate it with the quality of restoration of the treated teeth. Patients were retrieved from the files of the Operative Dentistry clinics (FOUFPel between 1996 and 2000. Twenty-two patients were recalled, which had 23 teeth treated with pulpotomy due to exposure by caries. Seven anterior and 16 posterior teeth composed the evaluated group, being all restored with composite resin. The age varied from 15-50 years (mean 23.9 and the follow-up mean was 34.52 months. Clinical and radiographic examinations were performed to evaluate the clinical status of treatment. The criteria used, clinically favorable and failure, were based on the following clinical exams: pulp vitality; sensitivity; and periapical alterations. The quality of the restorations was based on the USPHS criteria. Pulpotomy treatment was ranked as clinically favorable in 10 teeth (43.5%, 4 in anterior and 6 in posterior teeth. Failure was verified in 13 teeth (56.5%, 4 anterior and 9 posterior.

    The purpose of this noninferiority trial was to compare postoperative pain relief after one-visit root canal therapy (ORCT) with a pulpotomy performed with a new endodontic calcium-enriched mixture cement (PCEM) in human permanent molars with irreversible pulpitis. A total of 407 selected patients were randomly allocated into the ORCT group (n = 202) or the PCEM group (n = 205). Numerical Rating Scale questionnaires were used to record pain intensity (PI) by the patients during the first 7 days after treatment. While there was no statistically significant difference in the mean PI at baseline between the two study groups (P = 0.45), changes in mean PI were significantly different between them (P < 0.001). In the ORCT group, pain relief was achieved after 36 h [95% confidence interval (CI), 27.00-45.00], compared to 18 h in the PCEM group (95% CI, 15.00-21.00), a significant difference (P < 0.01). Comparison of the mean PI sum recorded over 7 days showed that patients in the ORCT group experienced significantly more pain than those in the PCEM group (P < 0.001); a similar difference was observed for pain in response to percussion tests (P < 0.001). Treatment with PCEM thus had the better pain-reducing effects than ORCT in irreversible pulpitis cases.

    The purpose of this study was to evaluate the effect of freeze-dried bone on amputated pulps. Fifteen primary and one permanent monkey teeth were treated with freeze-dried bone. As the control group, another fifteen primary teeth were treated with calcium hydroxide and fifteen primary and one permanent teeth with formocresol. Four other primary teeth pulps were amputated and sealed with tin foil and IRM as controls. Twelve mandibular incisors were left intact. Histologically all but three teeth treated with human freeze-dried bone after three months showed a complete or partial calcific barrier directly below the amputation site. Normal appearing odontoblastic cells were noted below the calcific barrier. The apical third was vital with an occasional chronic inflammatory cell visible. The histological findings of teeth treated with calcium-hydroxide were very similar to freeze-dried bone. All but four teeth showed a complete calcific barrier at the amputation site. The odontoblastic cells were normal in appearance and the inflammatory cell reactions decreased from the middle portion toward the apical region. The histological evaluation of the formocresol-treated teeth was comparable with previously published studies.

Materials and Methods: Total sample of 40 teeth from 20 children in the age group of 7-10 years which are noncarious having bilateral retained primary teeth were enrolled for the study. Nine teeth each were treated with collagen particles (group I and Pulpotec cement (group II, and the remaining samples were discarded due to various reasons. Both groups were randomly subdivided into three teeth each that were extracted after 7, 15, and 30 days intervals and examined histologically. Results: Moderate to severe inflammatory cells with newly formed blood vessels and disorganized odontoblastic cell layer was observed in group I after all three intervals with dentinal bridge formation in two specimens. On contrary, none of the specimens in group II showed any signs of inflammation, but there was a discontinuity in the odontoblastic layer lining along the dentin walls. Conclusion: Both materials were proven to be promising alternatives as pulp medicaments. However, collagen was found to be a better material.

    The purpose of this study was to assess the clinical and radiographic outcomes of a 1-minute application of full-strength Buckley's formocresol with concurrent hemostasis using the medicated cotton pledget in human primary teeth. Using a retrospective chart review, clinical and radiographic data were available for 557 primary molars in 320 patients. Descriptive statistics and survival analysis were used to assess outcomes. Overall clinical success, radiographic success, and cumulative 5-year survival rates were approximately 99%, 90%, and 87%, respectively. Internal root resorption (∼5%) and pulp canal obliteration (∼2%) were the most frequently observed radiographic failures. Thirty-nine teeth were extracted due to clinical and or radiographic failure. Mandibular molars were 6 times more prone to radiographic failure than maxillary molars. Success rates for the modified technique are comparable to techniques that use the 5-minute diluted or full-strength solutions reported in the literature. This 1-minute full-strength formocresol technique is an acceptable alternative to published traditional techniques.

    ABSTRACT Background: Vital pulpotomy is a single-stage procedure of surgical amputation of the coronal portion of exposed vital pulp, usually as a means of preserving the vitality and function of the remaining radicular portion. Aims and objectives: The aim of this study was to compare the clinical and radiographic success rates for ferric sulfate (FS), electrosurgery (ES) and laser pulpotomy in human primary molars. Materials and methods: In a randomized clinical trial, 30 primary molars indicated for pulpotomy in children aged 4 to 10 years were treated using either a FS (10 teeth), ES technique (10 teeth) and laser (10 teeth). Following the pulpotomy, the teeth were evaluated for clinical and radiographic success at 3, 6, 9 and 12 months on the basis of the presence of pain, sinus, mobility, internal and external resorption, periapical radiolucency, calcification in the canal and bone loss. Statistical analysis: The data were assessed with Chi-square test. Results: After 12 months of follow-up, both clinical and radiographic success rates were 100% in the laser group but only 80% in both ES and FS groups. There was statistically significant difference between the success rates of three groups (p pulpotomy showed better clinical as well as radiographical results than ES and FS pulpotomy. Laser pulpotomy was also found superior in terms of operating time, patient cooperation, ease of use and pain. Although results of the study showed the failure rates for electrosurgical pulpotomy to be equal to those for FS pulpotomy, electrosurgical pulpotomy being a nonpharmacological technique considered more favorable. Further studies using larger sample size and longer evaluation periods are suggested. How to cite this article: Gupta G, Rana V, Srivastava N, Chandna P.

    2011-08-01

    Full Text Available Statement of Problem: Pulpotomy is the most common pulp treatment in primary teeth. Final restoration of the pulpotomized primary molar can affect the success rate of treatment. Purpose: The aim of this study was to evaluate the success rate of formocresol pulpotomy in primary molars restored with stainless steel crowns as compared to those restored with amalgam.Materials and Method: In this randomized clinical trial study, 110 primary molars to be treated with pulpotomy were treated by a conventional pulpotomy technique. Then these teeth were randomly divided into 2 groups: amalgam and crown. 55 teeth were restored by stainless steel crown and 55 by amalgam. The clinical and radiographic evaluation was done at 6-12-24 months. The data were analyzed by Exact Fisher test.Results: During the 6 months of evaluation, no clinical and radiographic failure was seen. In the 12 months of follow up in the amalgam group, 1 case showed swelling and furcal radiolucency. During the 24 months of evaluation, mobility was seen in 2 teeth in the crown group, and in the amalgam group radiolucency was seen in 1 case, mobility in 1 case, and internal resorption in 1 tooth. Exact Fisher test showed that there was no significant difference in the success rate of pulpotomized molars restored by stainless steel crown and amalgam.Conclusion: If the tooth is selected correctly for pulpotomy, SSC and amalgam restoration can be used as the final restoration.

    The present in vivo study was performed to investigate the levels of the pro-inflammatory cytokines, interleukin (IL)-1α, IL-6, and IL-8, in primary molars for which pulpotomy was clinically indicated, and to evaluate the success rates of three different pulpotomy agents employed for cariously (CExp) or mechanically exposed (MExp) primary molars. Forty-seven primary molars were classified as MExp or CExp according to the type of pulpal exposure. Pulp tissue was harvested and analyzed using enzyme-linked immunosorbent assay (ELISA). Subsequently, three pulpotomy agents-calcium hydroxide (CH), mineral trioxide aggregate (MTA), and formocresol (FC)-were applied randomly, and the outcome was observed radiographically for 18 months. Levels of IL-6 and IL-8 were significantly higher in CExp pulp than in MExp pulp (P pulpotomy group, MExp teeth showed a higher success rate than CExp teeth. There was no significant difference in success rate between MExp and CExp teeth in both the FC and MTA groups. The levels of IL-6 and IL-8 have the potential to become indicators of pulp status and can be monitored by researchers to make the prognosis of vital pulp therapies less uncertain. As MTA and FC yielded higher rates of success than CH in CExp teeth, the choice of pulpotomy agent appears to be important in this context.

Pulpotomy procedure was performed, and the radicular pulp tissue of one molar capped with A. sativum oil in a cotton pellet, whereas the other molar capped with formocresol, the teeth evaluated clinically and radiographically before and after 6 months, using standard clinical and radiographical criteria. Statistically, these results revealed no significant difference between the radiographic findings of vital pulpotomy in primary molars with the two medicaments was found. Results: A. sativum oil offers a good healing potential, leaving the remaining pulp tissue healthy and functioning. Vital pulpotomy with allium sativa oil was given raise 90% success rate while that with formocresol was 85%. Conclusion: A. sativum oil is a biocompatible material that is compatible with vital human pulp tissue. It offers a good healing potential, leaving the remaining pulp tissue healthy and functioning.

    The aim of the present study was to clinically and radiographically evaluate Mineral Trioxide Aggregate (MTA) as an agent for pulpotomy in primary teeth and to compare it with that of Formocresol (FC) pulpotomy. Seventy first and second primary mandibular molars of children were chosen on patients who required minimum two pulpotomies in either arch or same arch. After the standardized technique of Pulpotomy with MTA and Formocresol, all molars were treated with a thick mix of Zinc oxide Eugenol cement into the coronal pulp chamber followed by preformed stainless steel crown. The children were followed up for clinical and radio graphical examination after 6, 12 and 24 month for Pain, Swelling, Sinus/fistula, Periapical changes, Furcation radiolucency and internal resorption. MTA represents 97% clinical success rate in comparison to Formocresol with 85% success. Radiographically also MTA showed more promising results with 88.6% success in comparison to Formocresol with 54.3%. Thus, MTA pulpotomy has emerged as an easier line of treatment to save the premature loss of primary teeth due to caries or trauma.

    The purpose of this multisite, multioperator, prospective, randomized, controlled clinical trial was to evaluate 2-year outcomes of diluted formocresol (DFC) compared to gray mineral trioxide aggregate (GMTA) as pulpotomy medicaments. Following the standard pulpotomy procedure, the pulp stumps of 252 primary molars in 168 healthy children were randomly covered with GMTA or DFC. Pulp chambers were filled with Intermediate Restorative Material (IRM(®)) and teeth were restored with stainless steel crowns. At each follow-up appointment, the clinical status of the treated tooth was assessed and radiographs were taken. A total of 694 clinical and radiographic evaluations were analyzed. Gender, study site, arch type, and tooth type did not influence treatment outcome. At the combined 6- to 24-month follow-up, clinical success in the DFC group was no different than for the GMTA group. Radiographically, a significantly lower success rate was found in the DFC group vs the MTA group at all time points (Pformocresol as pulpotomy medicaments.

    The aim of this study was to use clinical, radiographic and histological examinations to compare the dental pulp response in 162 premolar roots of eight dogs when trichloracetic acid (TCA), formocresol, mineral trioxide aggregate (MTA) and zinc oxide eugenol were used as pulpotomy agents. The teeth were divided into four groups. Following pulpotomy, the teeth were restored with amalgam. The animals were sacrificed at 48 h, 2, 4 and 8 weeks (two dogs at each interval). Histological evaluation indicated no cases with necrosis. After 8 weeks follow up, dentine bridge formation was evident in 20%, 50% and 91.7% of formocresol, TCA and MTA cases respectively. The first signs of bridge formation were seen for MTA at 2 weeks and for TCA at 4 weeks. MTA was superior to formocresol and TCA in treating pulps in dogs. However, bridge formation was seen in 50% of TCA cases after 8 weeks which is a desirable finding in pulpotomy procedures.

    Science.gov (United States)

    Anthonappa, R P; King, N M; Martens, L C

    2013-03-01

    Several papers have been published to illustrate the effectiveness of mineral trioxide aggregate (MTA) as a pulpotomy medicament. Most of these reports do not offer a critical assessment on the data quality. Therefore, this review evaluated whether the currently available evidence is of an appropriate quality to support the long-term effectiveness of MTA as a pulpotomy medicament in primary molars using a standardized assessment criterion. A comprehensive literature search of human clinical outcome studies, which employed MTA as a pulpotomy medicament in primary teeth, was conducted using the MEDLINE database. Two independent observers rated these articles using the standardized assessment criteria. Furthermore, based on the initial sample mentioned in the individual studies and the sample included for the final analysis, the drop-out rates were calculated. Twenty-two studies were included for quality assessment with an excellent interobserver agreement. None of the 22 studies obtained grade A, four studies attained grade B1, five were graded B2 and 13 received grade C. Based on the assessment criteria employed, there was no evidence that MTA was better than present materials and techniques as a pulpotomy medicament. Furthermore, given the low quality of data, it is highly desirable to establish standard requisites for conducting and reporting on pulp therapy studies in primary teeth so as to benefit both researchers and clinicians to produce high-quality studies that are comparable and to prevent the misuse of clinical material and resources.

    Full Text Available Vital pulp therapy (VPT is a biologic and conservative treatment modality to preserve the vitality and function of the coronal or remaining radicular pulp tissue in vital permanent teeth. A search was conducted via the Cochrane database, PubMed, MEDLINE, and Ovid for any articles with the criteria for "pulp-capping," or "pulp-capping materials" and "VPT outcomes" from 1978 to mid 2014. All articles were evaluated and the valid papers were selected. The outcomes of various VPT techniques, including indirect pulp treatment, direct pulp treatment, partial pulpotomy, and complete pulpotomy in vital permanent teeth were extracted. Although various studies have different research approach, most studies noted a favorable treatment outcome. Mineral trioxide aggregate (MTA appears to be more effective than calcium hydroxide (Ca(OH 2 for maintaining long-term pulp vitality after indirect and direct pulp-capping. However, it seems that the success rate for partial pulpotomy and pulpotomy with Ca(OH 2 is similar to MTA.

    Conclusion: Although general anesthesia provides an optimal condition for treating children with high caries risk, high failure rates of composite restorations were noted. Indirect pulp capping and ferric sulfate pulpotomy followed by stainless steel crown restorations are successful techniques and can be used to treat deep carious lesions.

    The purpose of this study was to determine the presence of formocresol in the plasma of children undergoing oral rehabilitation involving pulp therapy under general anesthesia. Thirty 2- to 6-year-old preschool children were enrolled in the study. Preoperative, intra-operative, and postoperative peripheral venous samples were collected from each child. All samples were analyzed for formaldehyde and cresol levels using gas chromatography with mass spectrometry detection. Eighty-five pulpotomies were performed ranging from 1 to 5 per child. Three hundred twelve blood samples were collected. Analysis revealed that formaldehyde was undetectable above baseline plasma concentration and cresol was undetectable in all samples. Benzyl alcohol (a byproduct of cresol metabolism) was present in all samples except the baseline preoperative samples. Benzyl alcohol concentrations ranged from 0 to 1 mg/ml. Formaldehyde was undetectable above baseline plasma concentration, and cresol was undetectable in subjects receiving pulpotomy treatment under general anesthesia. Benzyl alcohol was detected in the plasma of all subjects receiving pulpotomy treatment. The levels present were far below the Food and Drug Administration's recommended daily allowance. It is unlikely that formocresol, when used in the doses typically employed for a vital pulpotomy procedure, poses any risk to children.

    We have studied the changes presented by mediate and immediate roentgenographic images of indirect pulp capping and pulpotomies. In the cases of indirect pulp capping it was observed an increase of radiolucidity in the places occupied by Ca(OH)2, and sclerotic dentin was present. In pulpotomies, it was found the dentin bridge, which thickness increases with time. The radiolucidity of pulp chamber occupied by Ca(OH)2 was greater in the long time treatment. The radiopacity of non-vital dentin of walls and floor chamber was increased too. It has suggested that Ca++ ion would have migrated from its place and probably would take part in the synthesis of sclerotic dentin, independently of the vitality of the tissue.

    This manuscript reports the treatment trends in a pediatric dentistry clinic from 1980 to 1992 and discusses their implication in clinical teaching. Analysis of the records of the senior year pediatric dentistry students indicated: no significant change with time in the patients/student ratio, the number of preformed crowns, pulpotomies, and pulpectomies by student or by patient; a significant decrease in the number of one-surface and > or = 2-surface restorations by student and by patient; a significant increase in the number of pit-and-fissure sealants and preventive resin restorations by student and by patient. During the thirteen-year period, the students performed an average of 7.3 one-surface; 12.9 > or = 2-surface restorations; 5.5 preformed crowns; 6.4 pit-and-fissure sealants; 2.4 pulpotomies. There was a significant increase with time in the number of students who performed pit-and-fissure sealants.

    The purpose of this study was to study the histologic changes in the dental pulp following pulpotomy with Mineral Trioxide Aggregate (MTA) and Calcium hydroxide. Pulpotomies were performed on premolar teeth that were to be extracted for orthodontic reasons. The radicular pulp was capped with either MTA or Calcium hydroxide and restored with IRM. The teeth were extracted at 4 and 8 week intervals, fixed in 10% formalin and then kept in 5% nitric acid for 28 days for demineralization. Longitudinal sections were then prepared and viewed under light microscope. The pulps capped with MTA (at the end of 4 weeks and 8 weeks) showed dentin bridge formation which was more homogenous and continuous with the original dentin when compared to the pulps capped with calcium hydroxide. The pulpal inflammation was also less in the MTA group as compared to the calcium hydroxide group at the end of 4 and 8 weeks.

    Full Text Available Traumatic injuries occur commonly in children and adolescents and the prevalence of such injuries has increased over the last decade. Such injuries may result in pulpal exposure, which can endanger tooth vitality. Therefore, the treatment for such injuries should be carefully planned so as to preserve the pulp vitality. Teeth with immature roots pose a great challenge for the clinician and procedures like pulpotomy may prove effective as a treatment strategy. Such procedure may ensure continued root development and apexogenesis. Lasers have varied applications in the dental practice such as oral surgical procedures, cavity preparation, disinfection etc. This article is a case report on the use of diode laser for pulpotomy in a young permanent tooth with traumatically exposed pulp in an 8-year-old male.

    Since laser was introduced in the field of medicine in 1970's, its application range has continuously expanded. The application of laser in endodontics also increased due to its safety and effectiveness in dental treatments. The majority of the laser application researches in dentistry focused on dentin hypersensitivity, removal of carious tissues, tooth preparations, pulp capping or pulpotomy, and root canal treatment. In this article, we reviewed literature on the effects of laser in the treatments of dental and pulp diseases.

    Persistent hemorrhage after complete amputation of coronal pulp is a common clinical finding during pulpotomy procedure in primary teeth. These teeth are best managed with pulpectomy, but they have hyperemic pulp with some remaining vital tissue. Good chemico-biomechanical preparation of primary canals cannot guarantee complete removal of this vital tissue from inaccessible areas. Use of Ca(OH) 2 containing root filling pastes in vital pulp tissue can cause accelerated resorption of primary r...

    This study was carried out to investigate whether the changes in hematologic characteristic and color of pulpal bleeding is associated with clinical and histologic status of the pulp in primary teeth. A total of 211 primary molars in 103 patients, 3-6 years old, were treated. One hundred eight teeth had pulpectomy, 57 teeth had pulpotomy after pulp exposure during caries excavation, and 46 teeth had pulpotomy after accidental pulp exposure in sound dentin. After pulpal exposure, pulpal blood was collected in capillary tubes for blood color and hematologic assessment. Coronal and radicular pulp tissues were amputated for histologic assessment. Blood color was significantly darker in pulpectomy cases and samples with severe inflammation. The differences were clinically perceptible by the human eye. A significant negative correlation was detected between white blood cell (WBC) count and blood color. The counts of neutrophils and lymphocytes were significantly different between treatment groups. In addition, WBC, eosinophil, monocyte, neutrophil, and basophils counts were significantly different between degrees of inflammation in coronal pulp. Moreover, severe inflammation was higher in pulpectomy group versus pulpotomy groups. Pulp tissue calcification was also significantly higher in the pulpectomy cases. Considering the significant difference in pulpal blood color between the pulpectomy and pulpotomy cases, and between the different levels of pulpal inflammation; blood color can be a valid clinical diagnostic criterion of pulpal status and can be used for the selection of appropriate pulp treatment strategy. This study shows that pulp bleeding color can be used for selection of an appropriate pulp treatment method in primary teeth.

    To investigate whether formocresol, in Buckley's original formulation, is mutagenic in vivo to lymphocyte cultures obtained from the peripheral blood of children aged from 5 to 10 years old. These children were recruited from those attending the dental clinics of Recife City Council and the University of Pernambuco School of Dentistry, Brazil. The sample comprised 20 children who had primary teeth with cariously exposed vital pulps. Two venous blood samples were collected (6-8 ml) from each child, the first prior to vital pulpotomy (control group) and the second 24 h after pulpotomy (treated group). This research is a case-control study. The peripheral lymphocytes were grown in a complete culture medium consisting of 78% RPMI 1640 medium (a), supplemented with streptomycin (0.01 mg/ml), penicillin (0.005 ml(-1)), 20% fetal bovine serum (b) and 2% phytohemagglutinin (c). The lymphocytes were assessed for chromosomal aberrations via a previously published method which was modified. The cytogenetic analysis was performed in a blind test, where the slides were codified by an annotator and the scorers did not know which group they were analyzing. For each sample, this envolved the analysis of 200 metaphases. The level of significance adopted in the statistical test was 5.0% (pformocresol was mutagenic for one patient, raising doubt about the desirability of its use for pulpotomies in children. The results revealed that, from a statistical standpoint, formocresol is not mutagenic. However, further investigations are required, preferably with a larger sample, in patients needing more than one pulpotomy in order to observe whether an increase in the quantity of the drug would increase the quantity of chromosome aberrations and also to verify individual susceptibility to chromosome alterations with the use of formocresol.

    Objectives: The aim of this study was to evaluate the clinical and radiographic success rates of pulpotomized primary molar teeth restored with a compomer material with using United States Public Health Service (USPHS) criteria. Methods: In 173 primary molars of 156 child patients, aged within 4–9 years (mean age: 6.1±1.4 years), conventional pulpotomy treatment were performed. The teeth treated using calcium hydroxide, formocresol or ferric sulphate. After pulpotomy procedure, teeth were restored with compomer material. The teeth were evaluated as clinically and radiographically during a period of 12–24 months. Both of success of pulpotomy treatment and also restorative material (compomer material) were evaluated during follow-up period. The data were assessed with chi-square test. Results: At the end of the first year, 45% of initial treated teeth were checked, but only 18% were checked at the end of the second year. The first year success rates in the groups treated with CH, FC, and FS were 87.5%, 95%, and 79%, respectively, and, as the number of controllable patients was lower, the success rates on available teeth were determined to be 88.3% and 80%, respectively, according to the materials at the end of the second year. Restorations having been made, they were analyzed in accordance with USPHS criteria. Conclusions: At the end of the first year, 67.5% of compomer restorations were detected to be original and healthy and at the end of the second year, 57% were deemed healthy. No statistically significant relationships were found between marginal adaptation, secondary caries and pulpotomy success (chi-square test, P>.05). Among the three groups, there is no significant difference in terms of success. The least successful age group was defined as 4–6 years. PMID:22589580

    The purpose of this study was to assess and compare, in primary pig teeth, the pulp response after a pulpotomy using either Biodentine (a new tricalcium-silicate cement), white mineral trioxide aggregate (WMTA), or formocresol (FC) and repeat the same after direct pulp capping using either Biodentine, WMTA, or calcium hydroxide. A total of 180 primary teeth from 9 healthy 4-month-old female pigs were divided into 3 experimental periods (7, 28, and 90 days) for each material used for the pulpotomy and direct pulp capping treatments. Seven, 28, and 90 days later, the animals were euthanized and the specimens were prepared for histological examination and evaluation. The data collected from the histological examinations were statistically analyzed using Kruskal-Wallis and Dunn multiple comparison tests. In pulpotomy groups, there was a significant difference between Biodentine and WMTA vs FC in terms of inflammatory cell response and hard tissue formation. In direct pulp capping groups, there was only a significant difference between Biodentine and calcium hydroxide in terms of hard tissue formation in a 7-day period. Biodentine and white mineral trioxide aggregate are both suitable, biocompatible materials for pulp capping in primary teeth of pigs.

    Full Text Available Pulpotomy in deciduous teeth is a controversial issue, especially with regard to alternative materials used for the direct pulp capping of the root canal pulp tissue. The aim of the present study was to perform a histological analysis of the initial reaction of the root canal pulp tissue in rats, following pulpotomy and pulp capping with (1 green propolis extract, (2 iodoform paste, (3 green propolis extract + iodoform and (4 calcium hydroxide paste with saline solution. Analyses were performed after 24 hours, 72 hours and 7 days. The substances containing green propolis extract and iodoform led to the production of an intense inflammatory infiltrate and necrosis in the root canal pulp tissue throughout the analyses. In the calcium hydroxide group, inflammatory infiltrate only prevailed at the 72-hour evaluation. Among the substances tested, calcium hydroxide paste induced the lowest intensity of inflammatory response in the root canal pulp tissue. Longer studies should be carried out to analyze the pulp repair process following pulpotomy and pulp capping with the compounds analyzed.

    Full Text Available This study aimed at determining the prevalence of inflammatory root resorption and associated factors in 1068 primary mandibular molars in 453 children 3 to 12 years of age. Age, dental history and medical history were recorded using a questionnaire administered to the children's parents/caregivers. Previously trained and calibrated examiners assessed radiographic images of the primary molars by direct observation, with the aid of a viewing box. Root resorption (physiological or inflammatory, dental crown status (healthy, carious with no pulp involvement, carious with pulp involvement and evidence of restoration, and pulpotomy or pulpectomy were determined. Data analysis involved descriptive statistics, the chi-square test and a multiple logistic regression (p < 0.05. The prevalence of inflammatory root resorption was 16.2% (n = 173. The male gender (OR: 1.4; 95% CI, the 3-to-7-years age bracket (OR: 1.5; 95% CI, an unhealthy dental crown (OR: 8.7; 95% CI, caries with pulp involvement (OR: 7.4; 95% CI, pulpotomy (OR: 3.1; 95% CI, and pulpectomy (OR: 5.4; 95% CI were risk factors for the occurrence of inflammatory root resorption in primary molars. In conclusion, the prevalence of inflammatory root resorption in the present sample was 16.2%. Gender, age, an unhealthy tooth, caries with pulp involvement, pulpotomy, pulpectomy, and the absence of a restoration were associated with a higher occurrence of inflammatory root resorption in primary molars.

    The objectives of this study were (1) to evaluate clinically and radiographically the effects of mineral trioxide aggregate (MTA) as a pulp dressing after coronal pulp amputation (pulpotomy) in primary molars, (2) to compare the effects of MTA and formocresol in pulpotomized primary teeth. Sixty primary mandibular molars of thirty healthy children aged between 5-8 years were treated by conventional pulpotomy technique. The teeth on the right side are assigned to MTA (Group A) and the left side for the Formocresol (Group B). The children were examined clinically and radiographically every 6 months over a period of 36 months. Results of present study revealed that both MTA and Formocresol has the same effect on the first as well as second primary molars, with chi-square value being 1.1483 (P ≥ 0.05). None of the teeth in either group showed any clinical pathology, showing 100% success rate but radiographically formocresol group showed one case of internal resorption that was regarded as failure in the present study. MTA seems to be more promising predictable with positive response in vital pulp therapy in future than formocresol pulpotomy except for the cost factor.

    2005-08-15

    This study evaluated in vitro the influence of a temporary filling {zinc oxide-eugenol (ZOE)} and two pulpotomy agents {formocresol (FC) and ferric sulfate (FS)} on shear bond strength (SBS) of two dentin adhesives to the dentin of primary molars. A total of 80 dentin surfaces were prepared and randomly allocated into 10 groups of 8 specimens each. Groups were subjected to different treatments, which included covering with a paste of ZOE mixed at different powder:liquid (P:L) ratios, placement on a gauze soaked in FC or FS, or they received no pretreatment and served as a control. XRV Herculite composite cylinders were bonded to dentin surfaces using Prime and Bond NT adhesive resin or Opti Bond Solo Plus adhesive resin. SBSs were determined using the lnstron testing machine running at a crosshead speed of 0.5 mm/min. The use of ZOE mixed at the lower P:L ratio of 10g:2g significantly decreased the values of SBS of the two adhesives. The use of two pulpotomy agents (FC and FS) significantly decreased the SBS of the two adhesives. The bond strength to dentin of primary teeth was influenced by the pulpotomy agents used and the ZOE P:L ratio but not by the adhesive system used.

    The purpose of this study was to repeat a 1997 survey of current pulp therapy practice. The directors of dental school predoctoral pediatric dentistry programs (N=56) and board certified pediatric dentists (N=1200) were surveyed in 2005. More dental schools (83%) taught indirect pulp therapy (IPT) compared to 1997. Significantly more used glass ionomer for IPT with most dental schools and diplomates not re-entering a tooth after IPT. Over 30% of schools and diplomates do direct pulp cops using glass ionomer. For pulpotomy, diluted formocresol usage decreased in dental schools (54%) while ferric sulfate significantly increased (24%) and full strength remained at 22%. Shorter placement of pulpotomy medication was noted and ZOE alone the preferred base. Pulpectomy was advocated by 85% of 2005 schools and diplomates with ZOE filler use decreasing while iodoform/calcium hydroxide filler use increasing. More pediatric dentists are using glass ionomer for IPT and direct pulp capping, and there was a trend away from the use of 1:5 diluted formocresol with more using ferric sulfate for pulpotomy. For pulpectomy, most use ZOE but iodoform pastes and calcium hydroxide have increased in usage since 1997 Disagreements continue concerning when to use certain pulp therapies and some directors and diplomates did not follow the AAPD guidelines.

    Full Text Available Introduction:Despite the eight decades of widespread clinical use of formocresol growing evidence from both experimental and clinical studies clearly indicates that formaldehyde is leaking out during pulpotomy and may participate in the development of non-target tissue damage of local and systemic character. Special attention has been paid to pulp-capping materials and especially mineral trioxide aggregate (MTA as probable alternative of formocresol in vital pulpotomy in primary teeth, in line with its excellent biocompatibility and pro-dentinogenic properties. The overwhelming evidence that MTA is superior in terms of biological compatibilityand clinical success as compared to formocresol has conditioned the dramatic shift to MTA in routine pulpotomies.Objective: The aim of this study was to assess the biocompatibility of resorcinol/formalin (RF pulpotomy preparation in comparison to mineral trioxide aggregate (MTA and calcium hydroxide cement (CHC.Methods: Cell survival was assessed by the MTT-assay (after 48, 72 or 144 h in five cell lines, namely: HD-MY-Z, HEK-293, SH-SY-5Y, Neuro-2A, SaOS-2. In addition treatment-induced morphological perturbations and induction of necrosis and apoptosis were assessed in HEK-293.Results: RF evoked strong, concentration-dependent cytotoxicity, which was evident even at significant dilution of the parent solution. In general the cytotoxicity of RF was not greatly influenced by the exposure period, especially at the higher concentrations under evaluation. In contrast the MTA extracts proved to be generally devoid of cytotoxic effects. MTA treatment actually increased the viability of SaOS-2 osteosarcoma cells, which could be attributed to the presence of calcium ions in the MTA-eluate which in turn stimulates the proliferation of this cell line. The CH cement extracts showed marginal cytotoxicity which was far less pronounced than that of RF and slightly superior compared to MTA.Conclusions: In contrast to RF

    A case history is presented of a 10-year-old patient, who accidentally injured her maxillary central incisor. The fracture of the crown extended 2 mm below the crest of the alveolar bone. After a pulpotomy was done as a temporary measure, orthodontic appliances were placed by bonding brackets on the maxillary anterior teeth and fitting a sectional arch wire to extrude the fractured tooth. After successful extrusion, the fracture line was brought above the level of alveolar bone where successful restoration of the tooth by the acid-etch method could be accomplished.

    This case report describes the treatment of two immature maxillary central incisors in a 7-year-old female patient. She suffered complicated crown fracture because of trauma, and the root formation was incomplete. White mineral trioxide aggregate (MTA) was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. Follow-up evaluations showed successful treatment in terms of preservation of pulp vitality and demonstrated marked continuous physiological root development. During 10 years of follow-up, both teeth were clinically asymptomatic, and radiographic evaluations showed apparent root regeneration with apical root-end closure without pulp or periapical pathosis.

    Paraformaldehyde has been used in the past as a pulpotomy agent. However, it has a severe cytotoxic effect and may cause alveolar bone necrosis. Depulpin, a devitalizing agent containing 49% paraformaldehyde, is no longer used frequently due to its severe side effects. In the two cases described in the present study, Depulpin was used as a devitalizing agent during root canal treatment. It caused a gradual loss of sensibility in adjacent teeth, gingival necrosis, and osteomyelitis. This case report demonstrates the serious side effects of using a paraformaldehyde-containing paste as a devitalizing agent for pulp, particularly mandibular bone necrosis. PMID:27847756

    Persistent hemorrhage after complete amputation of coronal pulp is a common clinical finding during pulpotomy procedure in primary teeth. These teeth are best managed with pulpectomy, but they have hyperemic pulp with some remaining vital tissue. Good chemico-biomechanical preparation of primary canals cannot guarantee complete removal of this vital tissue from inaccessible areas. Use of Ca(OH) ₂ containing root filling pastes in vital pulp tissue can cause accelerated resorption of primary roots. The possible mechanism behind such extensive root resorption is discussed with review of literature. A case report of a child with 30 months follow-up is presented and discussed.

    ABSTRACT Radicular cysts are by far the most common cystic lesions of the jaw. However, those arising from primary teeth are comparatively rare, comprising only 0.5 to 3.3%. The aim of this paper is to present clinical, radiographic and histopathological characteristics of radicular cyst associated with a primary mandibular molar causing unusual displacement of the permanent successor. Extraction of primary tooth along with extirpation of cyst was done under local anesthesia. The displaced premolar was also extracted and then replanted in the socket after proper alignment. Healing was uneventful and the space of missing primary molar was maintained by band and loop space maintainer. The relationship between intracanal medicaments and rapid growth of cyst, as mentioned in literature was observed in our case too. Thus, pulpotomy treated primary teeth should receive periodic postoperative radiographic examination and absence of clinical symptoms does not mean that a pulpotomy treated tooth is healthy.

    The purpose of this study was to compare pain, efficacy and postoperative complications of anesthesia in first primary mandibular molars anesthetized with either intraligamentary (IL) or supraperiosteal (SP) anesthesia using a computer-controlled delivery system (CCDS). This randomized, controlled-crossover, blind clinical trial was conducted with 90 children requiring bilateral extraction, pulpotomy or restorative treatment of first mandibular primary molars. A CCDS was used to deliver IL anesthesia to 1 deciduous tooth and SP anesthesia to the contralateral tooth in each patient. Severity of pain and efficacy of anesthesia during the treatments were evaluated using the Wong-Baker Faces Pain Rating Scale (PRS) and comfort and side effects were assessed using post-injection and post-treatment questionnaires. Data were analyzed using χ2 and Mann-Whitney U tests. According to PRS scores, pain levels during extraction were significantly higher with IL when compared to SP. Patients reported significantly less pain during needle insertion with SP when compared to IL; however, rates of postoperative complications were significantly higher with SP when compared to IL. CCDS-administered IL anesthesia and SP anesthesia were similarly effective when used during restorative treatment and pulpotomy of primary mandibular molars; however, SP was more effective than IL when used during extraction procedures.

    Full Text Available The anterior teeth have the essential esthetics function , so when the trauma occur, the immediately treatment must be done to avoid its dysfunction. Andreas Jo reported in 1984 that 18 percent to 20 percent of traumatic injury in young permanent teeth caused the crown fractures with exposed pulps. This traumatic injury must be managed correctly to keep the pulp normal. Accurate examination and anamnesis must be done before treatment. The prompt treatment to relieve pain, to cover pulps from irritating material and maintain pulp vitality is neededOne alternative treatment for crown fracture with exposed pulp in young permanent is by using pulpotomy with calcium hydroxide. The function of calcium hydroxide is to maintain pulp vitality and stimulate reparative dentin and close the apex. Then, glass ionomer cement is used to support the pulp cap and then resin composite as temporary restoration to recover the function of mastication and esthetics, until the permanent restoration is made. In this case, ,the radiographic showed reparative dentin after four weeks of pulpotomy calcium hydroxide applied. So there was the fact that it took six month to make the apex is close from the beginning of treatment.DOI: 10.14693/jdi.v15i2.75

    The purpose of this study was to determine the level of agreement between pediatric dentists and endodontists at a pulp therapy symposium conjointly sponsored by the American Association of Endodontists (AAE) and the American Academy of Pediatric Dentistry (AAPD) on November 2-3, 2007. Presymposium and postsymposium tests were administered, and respondent answers were compared between pediatric dentists and endodontists. Opinions on 3 areas were sought: pulp therapy for cariously involved primary teeth; indirect pulp treatment (IPT) for cariously involved immature permanent teeth; and innovative treatment options including pulpal revascularization and regeneration. Results were analyzed with chi2 tests. Comparisons of presymposium and postsymposium responses and between the 2 groups of attendees indicated that the pediatric dentistry and endodontic communities agree that formocresol will be replaced as a primary tooth pulpotomy agent, that mineral trioxide is the first choice to take its place, that IPT in primary teeth holds hope as a replacement for pulpotomy, and that IPT is an acceptable pulp therapy technique for cariously involved young permanent teeth. Both groups believe that pulp revascularization and regeneration will be viable treatment modalities in the future. The AAE and the AAPD are positioned to begin preparation of best practice guidelines that share common language and treatment recommendations for pulp therapies performed by both specialties.

    Full Text Available Aim: The present study was undertaken to evaluate the effect of alternative pulpotomy agents such as glutaraldehyde and ferric sulfate on the shear bond strength of self-etch adhesive systems to dentin of primary teeth. Materials and Methods: Eighty human primary molar teeth were sectioned in a mesiodistal direction and divided into experimental and control groups. Lingual dentin specimens in experimental groups were treated with glutaraldehyde and ferric sulfate. Buccal surfaces soaked in water served as control group. Each group was then divided into two groups based on the adhesive system used: Clearfil SE Bond and Adper Prompt L-Pop. A teflon mold was used to build the composite (Filtek Z-250 cylinders on the dentinal surface of all the specimens. Shear bond strength was tested for all the specimens with an Instron Universal Testing Machine. The failure mode analysis was performed with a Scanning Electron Microscope (SEM. Results: The results revealed that glutaraldehyde and ferric sulfate significantly reduced the shear bond strength of the tested adhesive systems to primary dentin. Clearfil SE Bond showed much higher shear bond strength than Adper Prompt L Pop to primary dentin. SEM analysis revealed a predominant cohesive failure mode for both adhesive systems. Conclusion: This study revealed that the pulpotomy medicaments glutaraldehyde and ferric sulfate adversely affected the bonding of self-etch adhesive systems to primary dentin.

    This article describes successful use of calcium-enriched mixture (CEM) cement and Biodentine in apexogenesis treatment in two 8-year-old patients, one with immature permanent molar diagnosed primarily with irreversible pulpitis and the other with partially vital maxillary central incisor. After access cavity preparation, partial pulpotomy in molar and full pulpotomy in central was performed, and the remaining pulps was capped with either Biodentine or CEM cement, in each tooth. The crowns were restored with composite filling material at the following visit. The post-operative radiographic and clinical examinations (approx. average of 16 months) showed that both treated teeth remained functional, with complete root development and apex formation. A calcified bridge was produced underneath the capping material. No further endodontic intervention was necessary. Considering the healing potential of immature vital pulps, the use of CEM cement and Biodentine for apexogenesis might be an applicable choice. These new endodontic biomaterials might be appropriate for vital pulp therapies in an immature tooth. However, further clinical studies with longer follow-up periods are recommended. PMID:28179936

    Full Text Available Objective. This case report describes the changes in caries risk and activity and dental treatment of a 9-year-old patient who presented with signs and symptoms of Niemann-Pick disease type C (NPC. Treatment. The preventive dental treatment included instructions to caregivers for oral hygiene and diet. A calcium hydroxide pulpotomy and restorative dental treatments were performed in a dental office with desensitization techniques and behavioral management. The patient was attended every 3 months for the control of dental plaque biofilm, for topical fluoride application, and for observing the pulpotomized tooth. Results. The bacterial plaque biofilm was being adequately controlled by the caregiver. After 2 years, the clinical and radiographic examination of the pulpotomized tooth showed the absence of internal root resorption and bone rarefaction, and clinical examination showed tooth sensitivity, dental pain, and gingival swelling. Conclusion. The pulpotomy prevented clinical and radiographic success. Dentists must be aware of and be able to identify systemic and local aspects associated with caries risk of children with NPC disease. Furthermore, dentists must employ stringent preventive measures and provide instructions to caregivers to reduce caries risk.

    The purpose of this study was to test the hypothesis that there is no significant difference in the clinical and radiographic outcomes of diluted formocresol (DFC) compared to gray mineral trioxide aggregate (GMTA) pulpotomy in human primary molars. A total of 152 children with 252 primary molars met selection criteria. Of those, 119 and 133 teeth were randomly assigned to the GMTA and DFC groups, respectively. Periapical radiographs, taken pre- and/or postoperatively and at each 6-month follow-up, were digitized and evaluated by three blinded and calibrated examiners. Over a 42-month period, a total of 865 clinical and radiographic evaluations were conducted. There was no significant difference in clinical success, with the cumulative proportion of GMTA-treated teeth surviving at 0.98 vs DFC-treated teeth at 0.95 (P>.05). Radiographic success, however, was significantly greater for GMTA vs DFC, with the cumulative proportion of GMTA-treated teeth surviving at 0.90 vs DFC-treated teeth at 0.47 (Pformocresol when used as a medicament for primary molar pulpotomies.

    This was to define and compare the in vitro toxicity of grey MTA with that of white MTA on cultured human periodontal ligament (PDL) fibroblasts. PDL cells were obtained from sound first permanent molars and cultured in Dulbecco's Modified Eagle's Medium. Cultures were subjected to different concentrations of grey and white MTA (0.5, 5, 50 and 500 µg/ml) for 24 h at 37 °C. Cells that were not exposed to grey or white MTA served as the negative control. In vitro toxicity was assessed using MTT assay. The results were compared using ANOVA and Tukey statistical tests (p MTA presented higher in vitro toxicity than grey MTA. However, the differences were almost insignificant (p > 0.05). Both colours of MTA are biocompatible since they were both able to preserve PDL fibroblasts for up to 24 h. MTA is as a promising alternative in pulpotomy of primary teeth.

    Platelet-Rich Fibrin (PRF) was first described by Choukroun et al., (2001). It has been referred to as a second-generation platelet concentrate, which has been shown to have several advantages over traditionally prepared platelet-rich plasma. PRF has a physiologic architecture that is very favourable to the healing process, obtained due to the slow polymerization process. The development of platelet concentrate as bioactive surgical additives that are applied locally to promote wound healing stems from the use of fibrin adhesive. Developments in the field of tissue engineering have made the generation of artificial substitutes in several areas of medicine. Various clinical applications in endodontics include Periapical surgeries, Revascularisationprocedures, Regenerative pulpotomy, Perforation repair. This article aims to discuss the various applications of PRF in the field of Endodontics with few case reports.

    Full Text Available This case report describes the treatment of two immature maxillary central incisors in a 7- year-old female patient. She suffered complicated crown fracture because of trauma, and the root formation was incomplete. White mineral trioxide aggregate (MTA was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. Follow-up evaluations showed successful treatment in terms of preservation of pulp vitality and demonstrated marked continuous physiological root devel- opment. During 10 years of follow-up, both teeth were clinically asymptomatic, and radio- graphic evaluations showed apparent root regeneration with apical root-end closure without pulp or periapical pathosis.

    Full Text Available Preservation of the pulp in a traumatized immature fractured incisor tooth is of prime importance in order to achieve apexogenesis, a natural apical closure. The main factor influencing this is pulpal protection by a bioactive material proving optimum marginal seal in preventing any microleakage. This case report presents an 8-year-old female diagnosed with Ellis Class 3 fracture of immature tooth 11 involving the mesial pulp horn. Under rubber dam isolation, a partial pulpotomy was performed and the pulp was sealed using a new bioactive material BIODENTINE to stimulate apexogenesis, dentine replacement and pulp protection. The fractured segment was reattached for optimum esthetics, which was a concern for the patient. The patient was followed-up for 1, 3, 6 and 12 months, which revealed continued apical closure and maintenance of pulp vitality. The patient remained asymptomatic. This case report provides evidence for the potential use of Biodentine as an effective pulp capping material in the future.

    The search for new devices and technologies for endodontic procedures always has been challenging. Since the development of the ruby laser by Maiman in 1960 and the application of the laser for endodontics by Weichman in 1971, a variety of potential applications for lasers in endodontics have been proposed. With the development of thinner, more flexible and durable laser fibres, laser applications in endodontics have increased. Since laser devices are still relatively costly, access to them is limited. The purpose of this paper is to summarise laser applications in endodontics, including their use in pulp diagnosis, dentinal hypersensitivity, pulp capping and pulpotomy, sterilisation of root canals, root canal shaping and obturation and apicectomy. The effects of lasers on root canal walls and periodontal tissues are also reviewed.

    Full Text Available This case report describes the multidisciplinary management of subgingival horizontal crown-root fracture of an immature permanent maxillary central incisor in a 10-year-old boy. After removal of the fractured fragment, pulpotomy was performed within 48 h from the injury to promote apexogenesis. The tooth was orthodontically extruded until the fracture line was located above the alveolar bone level. Frenectomy, supracrestal fiberotomy, and crown lengthening were performed after adequate stabilization of the extruded tooth for 5 months. Finally, the tooth was restored with composite resin by using the acid etch technique. This report highlights that a multidisciplinary treatment approach with strict cooperation among specialists to manage a complicated crown-root fracture can save and restore a traumatized immature permanent tooth.

    Full Text Available Apexification is a procedure well recognized and accepted by clinicians and researchers alike. Apexification is an endodontic treatment that intends to stimulate of apex formation. One material in dentistry is calcium hydroxide that is most commonly used to induce an apical hard tissue barrier. Because of the capacity to promote environmental condition for tissue repair, calcium hydroxide can be used in the management of most endodontic problems, such as pulp capping, pulpotomy, root canal treatment, apexification and various endodontic situations. Due to its high alkalinity is has an antibacterial effect, promotes mineralization, induces healing, and initiates hard tissue formation. Although there have been many reports on the subject, the mechanisms of action are still unknown.

  13. Type II dens evaginatus of maxillary central incisor: An alternative approach

    2015-01-01

    Full Text Available Dens evaginatus is the developmental anomaly of tooth that exhibits protrusion of a tubercle from occlusal surfaces of premolar, and lingual surfaces of maxillary central incisor and lateral incisors. Dens evaginatus is common in Caucasian population. Saudi Arabia is also well evidenced of such cases. These tubercles have an enamel layer covering dentin core containing a thin extension of pulp. These cusp-like protrusions are susceptible to pulp exposure from wear or fracture because of malocclusion. Type II dens evaginatus involves normal pulp with immature root apex. Materials to enhance the pulpal recession or pulpotomy procedures indicated in such cases require long time and efforts to ensure pulpal recession or root maturity, respectively. Also prolonged treatment has risk of fracture of the cusp and reinfection and requires patient commitment for the follow-up procedures. Present case describes the use of mineral trioxide aggregate (MTA in type II dens evaginatus of maxillary central incisor.

    Full Text Available Mineral trioxide aggregate (MTA is a powder containing calcium silicate composed of hydrophilic particles which harden at the presence of moisture. MTA was initially introduced as a root end filling material. Due its practical advantages that include superior biocompatility, effective sealing capability, and the ability to improve regeneration of the pulp and peripheral root tissues, it is used in different clinical applications such as pulp capping, apexification, pulpotomy and perforation. Despite being a promising material in endodontic treatment, MTA is not commonly used. Long setting time is the main clinical disadvantage of MTA. The aim of this review is to provide an overview of the current literature concerning the setting mechanism of MTA, accelerators and devices used to evaluate various steps of the hardening process.

    Vital pulp therapy (VPT) is the preferred conservative treatment for preservation of symptomatic pulps in immature permanent teeth. The present case report summarizes VPT of an immature permanent molar with irreversible pulpitis associated with apical periodontitis in a 9-year-old boy. Cervical pulpotomy was performed and radicular pulp stumps were covered with calcium-enriched mixture (CEM) cement; the tooth was then restored with stainless steel crown. After a 50-month follow-up period, the pulpotomized molar was clinically functional and asymptomatic. Moreover, radiographic evaluation revealed evidence of complete root development as well as normal periodontal ligament around the roots. The successful outcome achieved through VPT using CEM biomaterial in the reported case suggests that this method may produce favorable outcome for vital immature permanent teeth with irreversible pulpitis and periapical disease.

    In primary molars with root perforations of endodontic origin, tooth extraction and space maintainer are recommended. Calcium-enriched mixture (CEM) cement is a new biomaterial demonstrating favorable sealability/biocompatibility. This report presents a novel treatment modality for cases of primary molar teeth with root perforations associated with a periodontal lesion due to extensive inflammatory root resorption, whereby CEM was used as a perforation repair/pulpotomy biomaterial. Three cases of primary molar root perforations due to inflammatory resorption were selected; all cases were associated with furcal lesions of endodontic origin. Pulp chambers were accessed/irrigated with NaOCl; the root canal orifices were filled with CEM and restored with stainless steel crowns. Clinical/radiographic examinations up to 17 months revealed that all teeth were functional and free of signs/symptoms of infection and all had complete bone healing. Further trials are suggested to confirm CEM use for management of root perforations in primary molars exhibiting root perforation.

    The purpose of this multisite, multioperator, prospective, randomized, controlled clinical trial was to evaluate the 6-month outcomes of diluted formocresol (DFC) compared to gray mineral trioxide aggregate (GMTA) as pulpotomy medicament. Determined by a power analysis, 252 molars of 152 children were recruited. The teeth were randomly assigned to receive GMTA or DFC. At the 6-month follow-up, 118 children with 203 treated teeth were evaluated. Four blinded and calibrated evaluators scored each radiograph for pathologies. Clinical success was similar for DFC (97%) and GMTA (100%), (P<.09). Radiographic success differed significantly (P<.04) for DFC (86%) and GMTA (95%). Pulp canal obliteration was radiographically observed in 25% of the DFC group and in 37% of the GMTA group (P=.07). Dentin bridging was observed in 22% of the GMTA group but was not found in the DFC group (P<.01). Teeth treated with GMTA showed more favorable radiographic outcomes than DFC at 6 months post-treatment.

    This report presents a case of dentigerous cyst associated with a formocresol pulpotomized deciduous molar detected during routine examination. Dentigerous cyst is an epithelial-lined developmental cavity that encloses the crown of an unerupted tooth at the cementoenamel junction. The present case describes a 9-year-old girl sent to the dental clinic by her dentist, who had accidentally discovered in the panoramic radiograph a single, unilocular, well-defined, radiolucent area enclosing the second left unerupted mandibular premolar. The second left primary molar had been pulpotomized 2 years before and buccal swelling without redness occurred near the tooth, evidencing bone expansion. Surgical treatment was carried out, the tooth was extracted, and a cystectomy was performed under local anesthesia in the dental office. The histological study confirmed the suspected diagnosis of dentigerous cyst. The relation between pulpotomy and dentigerous cysts is discussed.

    This was to assess and compare the in vitro toxicity of formocresol, ferric sulphate and MTA on cultured human periodontal ligament (PDL) fibroblasts. PDL cells were obtained from sound first permanent molars and cultured in Dulbecco's modified Eagle's medium. PDL cells were subjected to different concentrations of formocresol, ferric sulphate, and grey MTA for 24, 48, and 72 h at 37 °C. Cells that were not exposed to the tested materials served as the negative control. In vitro toxicity was assessed using MTT assay. Statistical analysis of data was accomplished using ANOVA and Tukey statistical tests (pformocresol>ferric sulphate>grey MTA. Only grey MTA had comparable cell viability to the negative control, the other tested materials were significantly inferior at the three exposure periods (pformocresol. However, considering MTA's unavailability and high price in Jordan, ferric sulphate may be the best alternative to formocresol in pulpotomy of primary teeth.

    For children to receive needed oral health care, adequate training at both the predoctoral and postdoctoral levels of dental education is required, but previous studies have found inadequacies in predoctoral education that lead to general dentists' unwillingness to treat certain young populations. As another way of assessing predoctoral preparation, the aim of this study was to determine the perspectives of first-year residents and pediatric program directors about residents' preparedness to enter advanced education programs in pediatric dentistry. Surveys were sent to all 74 U.S. program directors and 360 first-year residents. The survey focused on procedures related to prevention, behavior management, restorative procedures, pulp therapy, sedation, and surgery, as well as treating patients funded by Medicaid and with special health care needs. Among the first-year residents, 173 surveys were returned for a 48% response rate; 61 directors returned surveys for an 82% response rate. Only half of the residents (55%) reported feeling adequately prepared for their first year in residency; less than half cited adequate preparation to place stainless steel crowns (SSCs) (42%) and perform pulpotomies (45%). Far fewer felt adequately prepared to provide treatment for children six months to three years of age, including examinations (29%), infant oral exams (27%), and children with severe caries (37%). The program directors were even less positive about the adequacy of residents' preparation. Only 17% deemed them adequately prepared to place SSCs and 13% to perform pulpotomies. Approximately half reported their first-year residents were inadequately prepared to treat very young children and children with severe caries (55% each). This study found that the perceived inadequacy of predoctoral education in pediatric dentistry was consistent at both the learner and educator levels, supporting previous studies identifying inadequacies in this area.

    The aim of this study was to use clinical, radiographic, and histologic examinations to compare the relative success of gray mineral trioxide aggregate (MTA), white MTA, and formocresol as pulp dressings in pulpotomized primary teeth. Twenty-four children, each with at least 3 primary molars requiring pulpotomy, were selected for this study's clinical and radiographic portion. An additional 15 carious primary teeth planned for serial extraction were selected for this study's histologic portion. All selected teeth were evenly divided into 3 test groups and treated with pulpotomies. Gray MTA was used as the pulp dressing for one third of the teeth, white MTA was the dressing for one third, and the remaining one third were treated with formocresol. The treated teeth selected for the clinical and radiographic evaluations were monitored periodically for 12 months. The treated teeth selected for histologic study were monitored periodically and extracted 6 months postoperatively. Four children with 12 pulpotomized teeth failed to return for any follow-up evaluations in the clinical and radiographic study. Of the remaining 60 teeth in 20 patients, 1 tooth (gray MTA) exfoliated normally and 6 teeth (4 white MTA and 2 formocresol) failed due to abscesses. The remaining 53 teeth appeared to be clinically and radiographically successful 12 months postoperatively. Pulp canal obliteration was a radiographic finding in 11 teeth treated with gray MTA and 1 tooth treated with white MTA. In the histologic study, both types of MTA successfully induced thick dentin bridge formation at the amputation sites, while formocresol induced thin, poorly calcified dentin. Teeth treated with gray MTA demonstrated pulp architecture nearest to normal pulp by preserving the odontoblastic layer and delicate fibrocellular matrix, yet few inflammatory cells or isolated calcified bodies were seen. Teeth treated with white MTA showed a denser fibrotic pattern, with more isolated calcifications in the

    In children, dental caries is among the most prevalent chronic diseases worldwide. Pulp interventions are indicated for extensive tooth decay. Depending on the severity of the disease, three pulp treatment techniques are available: direct pulp capping, pulpotomy and pulpectomy. After treatment, the cavity is filled with a medicament.This is an update of a Cochrane review first published in 2003. The previous review found insufficient evidence regarding the relative efficacy of these interventions, combining one pulp treatment technique and one medicament. To assess the effects of different pulp treatment techniques and associated medicaments for the treatment of extensive decay in primary teeth. We searched the Cochrane Oral Health Group's Trials Register (to 25 October 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 9), MEDLINE via OVID (1946 to 25 October 2013), EMBASE via OVID (1980 to 25 October 2013) and the Web of Science (1945 to 25 October 2013). We searched OpenGrey for grey literature and the US National Institutes of Health Trials Register and the World Health Organization (WHO) Clinical Trials Registry Platform for ongoing trials. We placed no restrictions on the language or date of publication when searching the electronic databases. Eligible studies were randomised controlled trials comparing different pulp interventions combining a pulp treatment technique and a medicament in children with extensive decay involving dental pulp in primary teeth. Two review authors independently carried out data extraction and risk of bias assessment in duplicate. We contacted authors of randomised controlled trials for additional information if necessary. The primary outcomes were clinical failure and radiological failure, as defined in trials, at six, 12 and 24 months. We performed data synthesis with pairwise meta-analyses using fixed-effect models. We assessed statistical heterogeneity using by I(2) coefficients

    Objective The aim of the present study is to investigate the prognosis and influencing factors of crown-fractured young permanent teeth with pulp exposure. Methods Case records of crown-fractured young permanent teeth with pulp exposure in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology during 1991 to 2008 with more than 2 years follow-up were collected. These patients were treated with pulpotomy at the first visit at our hospital no matter whether these teeth were treated or untreated with direct pulp capping. The age of patients, interval between trauma and treatment, root development, mobility and tenderness to percussion were recorded. The prognosis was analyzed and Logistic regression was used to analyze the influencing factors. Results Totally 118 cases satisfied the inclusion criteria, including 136 crown-fractured teeth with pulp exposure. The patients of (8.8±1.2) years old were periodically monitored for (46.1±22.0) months. The success rate of pulpotomy after pulp exposure was 85.3%. Pulp necrosis occurred in 20 teeth (25.0±19.0) months after trauma. The extent of tenderness to percussion showed significant correlation with pulp necrosis, while the age of the patients, interval between injury and treatment, and mobility of the teeth were not related to pulp necrosis. Conclusion The success rate of pulpotomy after pulp exposure is good. Tenderness to percussion is an important signal of pulp necrosis. There are no evidence about the relationship between the patient's age, interval between injury and treatment, mobility of the pulp-exposed teeth and the pulp prognosis.%目的 回顾分析年轻恒牙冠折露髓后的预后及其影响因素.方法 对1991-2008年就诊于北京大学口腔医院儿童口腔科的冠折露髓年轻恒牙的病历资料进行回顾分析,要求患者初诊治疗为活髓切断术或直接盖髓后改行活髓切断术且患者复诊时间大于2年.记录患者的年龄、初

    To determine the age and sex characteristics of the children and type of dental procedures performed under dental general anesthesia (DGA) and to assess the results after six months to one year's follow-up. A sample of 30 patients treated under dental general anesthesia (DGA) during 2006-2007 in the Department of Pediatric Dentistry of China Medical University was reviewed. All the teeth were treated one time. The dental procedures performed included caries restoration, indirect pulp capping, pulpotomy, root canal therapy (RCT) and dental extraction. Oral prophylaxis and topical fluoride applications were performed on all teeth. Pit and fissure sealing was performed on all healthy premolars and molars. SPSS10.0 software package was used for statistical analysis. Chi-square test was used to analyze the difference of the sex distribution in different age group and the difference of dental procedures performed between the primary teeth and the permanent teeth. The age of the patients ranged from 19 months to 14 years. The mental retardation patients accounted for 10% and mental healthy patients accounted for 90% of the sample studied. Males were more than females with the ratio about 2 to 1 in each age group. The dental procedures performed were caries restoration (18.67%), indirect pulp capping (23.26%), pulpotomy (0.77%), RCT (29.16%), dental extractions (2.05%) and fissure sealants (26.09%). The percentage of RCT was higher than that of caries restoration in the primary teeth, whereas the result was opposite as for the permanent teeth as indicated by Chi-square test (X(2)=11.630, P=0.001). New dental caries was not found except 2 patients who suffered from dysnoesia and were not cooperative to have regular examination. Fillings were lost in 3 cases, with 3 anterior teeth and 2 posterior teeth after RCT. All the children could cooperate except two mental retardation patients during the follow-up visit. Caries restoration and RCT are the most frequently performed

  8. The use of stainless steel crowns.

    Seale, N Sue

    2002-01-01

    The stainless steel crown (SSC) is an extremely durable restoration with several clear-cut indications for use in primary teeth including: following a pulpotomy/pulpectomy; for teeth with developmental defects or large carious lesions involving multiple surfaces where an amalgam is likely to fail; and for fractured teeth. In other situations, its use is less clear cut, and caries risk factors, restoration longevity and cost effectiveness are considerations in decisions to use the SSC. The literature on caries risk factors in young children indicates that children at high risk exhibiting anterior tooth decay and/or molar caries may benefit by treatment with stainless steel crowns to protect the remaining at-risk tooth surfaces. Studies evaluating restoration longevity, including the durability and lifespan of SSCs and Class II amalgams demonstrate the superiority of SSCs for both parameters. Children with extensive decay, large lesions or multiple surface lesions in primary molars should be treated with stainless steel crowns. Because of the protection from future decay provided by their feature of full coverage and their increased durability and longevity, strong consideration should be given to the use of SSCs in children who require general anesthesia. Finally, a strong argument for the use of the SSC restoration is its cost effectiveness based on its durability and longevity.

    The success of pulpotomy of young permanent teeth depends on the proper selection of dressing materials. This study aimed to evaluate the histological and histomorphometric response of dentin-pulp complex to the enamel matrix derivative (Emdogain(®) gel) compared to that of calcium hydroxide when used as a pulp dressing in immature young permanent dogs' teeth. Dentin-like tissues bridging the full width of the coronal pulp at the interface between the injured and healthy pulp tissues were seen after 1 month in both groups. With time, the dentin bridge increased in thickness for calcium hydroxide but disintegrated and fully disappeared for Emdogain-treated group. Progressive inflammation and total pulp degeneration were only evident with Emdogain-treated group. The root apices of Emdogain-treated teeth became matured and closed by cementum that attached to new alveolar bone by a well-oriented periodontal ligament. In young permanent dentition, Emdogain could be a good candidate for periodontium but not dentino-pulpal complex regeneration.

    Full Text Available Mineral trioxide aggregate (MTA is a material that has been used worldwide in several clinical applications, such as apical barriers in teeth with immature apices, repair of root perforations, root-end filling, pulp capping, and pulpotomy. The purpose of this case report was to describe successful revascularization treatment of an immature mandibular right second premolar with apical periodontitis in a 9-year-old female patient. After preparing an access cavity without anesthesia, the tooth was isolated using a rubber dam and accessed. The canal was gently debrided using 5% sodium hypochlorite (NaOCl and 3% hydrogen peroxide irrigant. And then MTA was packed into the canal. X-ray photographic examination showed the dentin bridge 5 months after the revascularization procedure. Thickening of the canal wall and complete apical closure were confirmed 10 months after the treatment. In this case, MTA showed clinical and radiographic success at revascularization treatment in immature permanent tooth. The successful outcome of this case suggests that MTA is reliable and effective for endodontic treatment in the pediatric dentistry.

  11. Reparative Dentinogenesis Induced by Mineral Trioxide Aggregate: A Review from the Biological and Physicochemical Points of View

    2009-01-01

    Full Text Available This paper aims to review the biological and physicochemical properties of mineral trioxide aggregate (MTA with respect to its ability to induce reparative dentinogenesis, which involves complex cellular and molecular events leading to hard-tissue repair by newly differentiated odontoblast-like cells. Compared with that of calcium hydroxide-based materials, MTA is more efficient at inducing reparative dentinogenesis in vivo. The available literature suggests that the action of MTA is attributable to the natural wound healing process of exposed pulps, although MTA can stimulate hard-tissue-forming cells to induce matrix formation and mineralization in vitro. Physicochemical analyses have revealed that MTA not only acts as a “calcium hydroxide-releasing” material, but also interacts with phosphate-containing fluids to form apatite precipitates. MTA also shows better sealing ability and structural stability, but less potent antimicrobial activity compared with that of calcium hydroxide. The clinical outcome of direct pulp capping and pulpotomy with MTA appears quite favorable, although the number of controled prospective studies is still limited. Attempts are being conducted to improve the properties of MTA by the addition of setting accelerators and the development of new calcium silicate-based materials.

    The aim of this study was to compare the effect of ferric sulfate (FS) to that of dilute formocresol (DFC) as pulp dressing agents in pulpotomized primary molars. Ninety-six primary molars in 72 children were treated by a conventional pulpotomy technique. Fifty-eight teeth were treated by a FS solution for 15 sec, rinsed, and covered by zinc oxide-eugenol paste (ZOE). In another 38 teeth, a cotton pellet moistened with 20% DFC was placed for 5 min, removed, and the pulp stumps were covered by ZOE paste. The teeth of both groups were sealed by a second layer of intermediate restorative material (IRM) and restored with a stainless steel crown. This is a report of the clinical and radiographic examination of 55 teeth dressed with FS and 37 teeth fixed with DFC, that have been treated 6 to 34 months previously (mean 20.5 months). Four teeth were excluded from the study due to failure of the patient to present for recall. Success rates of 92.7% for the FS, and of 83.8% for the DFC were not significantly different. Four teeth (7.2%) of the FS group and two (5.4%) of the DFC group presented internal resorption. Inter-radicular radiolucencies were observed in two teeth of the FS group and three teeth of the DFC group. The latter also presented periapical lesions. Success rates of both groups were similar to those of previous studies utilizing the traditional Buckley's formocresol.

    Full Text Available Background: Microleakage in Stainless Steel Crowns (SSC margins leads to seepage of oral fluids and bacteria and it is one of the reasons for treatments failures. The aim of this study was to assess the effect of zinc phosphate, glass Ionomer and polycarboxylate cements on microleakage of stainless steel crowns for primary pulpotomized molar teeth. Materials and Methods: In this experimental in vitro study, 60 extracted primary molar teeth were randomly divided in to three groups (n=20. Stainless steel crowns were fitted for each tooth after pulpotomy procedures. Crowns were luted with a zinc phosphate, glass ionomer or polycarboxylate cement. All specimens were stored in 100% humidity at 37o C for 1 hour and termocycled 500 times (5ºC to 55ºC with a 30 seconds dwell time and then immersed in 0.5% basic fuschin solution for 24 hours. The specimens were sectioned buccolingually and each section was evaluated for microleakage under a stereomicroscope.Results: In zinc phosphate group 45% of spicemens and in glass ionomer group there was 5% of spicemens showed leakage extending on to occlusal aspect and in polycarboxylate group none of the spicemens had this situation. According to the kruskal wallis test in all groups there were significant differences in microleakage (p< 0.001.Conclusion: The use of zinc phosphate cement resulted in the highest percentage of microleakage. The microleakage of SSCs cemented with polycarboxylate and glass ionomer were similar.

    Traumatic injuries and dental caries can be a big challenge to immature teeth. In these cases, the main purpose of treatment is to maintain the pulp vitality. The purpose of this study was to investigate the effect of low-level laser therapy on accelerating the rate of dentinogenesis in pulpotomy of immature permanent teeth (apexogenesis). Three dogs, 4-6 months old, were used in this study. One jaw in each dog was randomly assigned to laser irradiation group. All selected teeth were pulpotomized with mineral trioxide aggregate (MTA) and restored with amalgam. In the laser group, the Ga-Al-As laser (810 nm, 0.3 W, 4 J/cm(2), 9 s) was used on buccal and lingual gingiva of each tooth in 48 h intervals for 2 weeks. In order to observe the newly formed dentine, tetracycline was injected on the 1st, 3rd, 7th, and 14th day after the operation. Then, ground sections of teeth were observed under a fluorescence microscope. The data was analyzed with Generalized Estimating Equations (GEE) test. The mean distance between the lines of tetracycline formed on the 1st and 14th day was significantly higher in the laser group (P = 0.005). Within the limitation of this study, irradiation of Ga-Al-As laser (810 nm) can accelerate the rate of dentinogenesis in apexogenesis of immature permanent teeth with MTA in dogs.

    To present comparative study aims to assist the practitioner to choose between behavior modification (BM) techniques, pharmacologic sedation (N2O-O2 alone or combined with midazolam 0.5 mg/ kg) or routine general anesthesia (GA) for the most successful approach in enabling pediatric dental care. Dental records of 56 children treated in a university dental clinic between 2006-2016 were reviewed, and data on age, gender, required treatment (amalgam restorations, composite restorations, pulpotomy, and stainless steel crowns [SSC]), treatment approaches and therapeutic success at final follow-up were retrieved. Treatment under GA had the best success rates compared to both BM and pharmacologic sedation. N2O-O2 alone had a 6.1-fold greater risk of failure compared to N2O-O2+midazolam (p- <0.008). Amalgam restorations had a 2.61-fold greater risk of failure than SSC (p- <0.008). The GA mode yielded significantly greater success than the N2O-O2 mode alone. There were no significant differences in success rates between GA and combined midazolam 0.5 mg/kg+N2O-O2. When choosing restoration material, it is important to remember the high success rate of SSC compared to amalgam restoration.

    The purpose of this study was to compare the cell viability of dental pulp cells treated with Biodentine (Septodont, Saint-Maur, France) and mineral trioxide aggregate (MTA) and the in vitro and in vivo expression of mineralization markers induced by the 2 materials. Human dental pulp cells isolated from 6 permanent teeth were stimulated with Biodentine and MTA extracts. Cell viability was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay, and quantitative reverse-transcriptase polymerase chain reaction was used to determine the expression of mineralization markers. Specimens of teeth from dogs treated with Biodentine and MTA after pulpotomy were used to determine the presence of osteopontin and alkaline phosphatase by immunohistochemistry and runt-related transcription factor 2 by immunofluorescence. No significant differences in cell viability were found between MTA and Biodentine extracts and controls after 24 and 48 hours (P > .05). After 48 hours, osteopontin (SPP1), alkaline phosphatase (ALP), and runt-related transcription factor 2 (RUNX2) expression was higher in MTA and Biodentine than in controls (P Biodentine than in MTA samples (P Biodentine (P = .2). Also, no significant difference in the number of cells labeled for runt-related transcription factor 2 by immunofluorescence was observed between materials (P > .05). Biodentine stimulated similar markers as MTA, but staining was more intense and spread over a larger area of the pulp tissue. Copyright © 2016 American Association of Endodontists.

    Full Text Available The restorative management of deep carious lesions and the preservation of pulp vitality of immature teeth present real challenges for dental practitioners. New tricalcium silicate cements are of interest in the treatment of such cases. This case describes the immediate management and the follow-up of an extensive carious lesion on an immature second right mandibular premolar. Following anesthesia and rubber dam isolation, the carious lesion was removed and a partial pulpotomy was performed. After obtaining hemostasis, the exposed pulp was covered with a tricalcium silicate cement (Biodentine, Septodont and a glass ionomer cement (Fuji IX extra, GC Corp. restoration was placed over the tricalcium silicate cement. A review appointment was arranged after seven days, where the tooth was asymptomatic with the patient reporting no pain during the intervening period. At both 3 and 6 mon follow up, it was noted that the tooth was vital, with normal responses to thermal tests. Radiographic examination of the tooth indicated dentin-bridge formation in the pulp chamber and the continuous root formation. This case report demonstrates a fast tissue response both at the pulpal and root dentin level. The use of tricalcium silicate cement should be considered as a conservative intervention in the treatment of symptomatic immature teeth.

    The objective of this study was to determine the prevalence, severity, and duration of postoperative pain in children undergoing general anesthesia for dentistry. This prospective cross-sectional study included 33 American Society of Anesthesiology (ASA) Class I and II children 4-6 years old requiring multiple dental procedures, including at least 1 extraction, and/or pulpectomy, and/or pulpotomy of the primary dentition. Exclusion criteria were children who were developmentally delayed, cognitively impaired, born prematurely, taking psychotropic medications, or recorded baseline pain or analgesic use. The primary outcome of pain was measured by parents using the validated Faces Pain Scale-Revised (FPS-R) and Parents' Postoperative Pain Measure (PPPM) during the first 72 hours at home. The results showed that moderate-to-severe postoperative pain, defined as FPS-R ≥ 6, was reported in 48.5% of children. The prevalence of moderate-to-severe pain was 29.0% by FPS-R and 40.0% by PPPM at 2 hours after discharge. Pain subsided over 3 days. Postoperative pain scores increased significantly from baseline (P < .001, Wilcoxon matched pairs signed rank test). Moderately good correlation between the 2 pain measures existed 2 and 12 hours from discharge (Spearman rhos correlation coefficients of 0.604 and 0.603, P < .005). In conclusion, children do experience moderate-to-severe pain postoperatively. Although parents successfully used pain scales, they infrequently administered analgesics.

    Full Text Available Platelet-reach plasma (PRP is an attractive tool in regenerative medicine due to its ability to stimulate proliferation and differentiation of stem cells. Since dental pulp derived stem cells are recognized as central in apexogenesis, the aim of the study was to evaluate radiologically and histologically effects of PRP on apexogenesis in teeth with immature roots. The study included eight monkeys (Cercopithecus Aethiops divided in two equal groups for evaluation 3 and 12 months after treatment. All participants obtained the same treatment including pulpotomy and after-treatment with: hydroxiapatite (HA-incisor and HA+canine PRP. Radiological evaluation was performed using the long cone paralleling technique for recording of defined parameters and histological evaluation was performed using tissue removed en block for the observation of parameters related to apexogenesis. The results obtained radiologically and histologically have shown increase in bridge formation in HA+PRP (75% group after 3 months comparing to HA group (50%. Contrary to that, after 12 months there were no significant differences between groups. The root delay was not registered in the HA+PRP group contrary to HA group where it was registered in 25% after 12 months. Results of the study suggest that PRP is a powerful tool for intensive and rapid apexogenesis since it offers clear and comprehensive results (mostly in the first three months which are early radiologically visible without any failure in the proposed requests.

    This study aimed to investigate the wound healing process of injured pulp tissues with Emdogain gel (EMD). Pulpotomy was performed for the first molars of the mandibles in rats. EMD or Vitapex (VIT)-containing calcium hydroxide was applied to the exposed pulp tissues. The treated teeth were extracted after 7, 14, and 28 days and prepared for histologic examination. In the VIT-treated group, the number of interleukin-1 beta (IL-1 beta)-expressing macrophages initially increased, followed by that of transforming growth factor-beta1 (TGF-beta1)-expressing macrophages. The number of cells expressing bone morphogenetic proteins (BMPs) gradually increased with reparative dentin formation. Meanwhile, in the EMD-treated group, cells expressing IL-1 beta or TGF-beta1 were few. However, the number of BMP-expressing cells, partly macrophages, increased in the early phase, and large amounts of reparative dentin were observed. This study demonstrated that different healing processes existed for EMD and VIT. BMP-expressing macrophages might play important roles in reparative dentin formation.

    Full Text Available The success of pulpotomy of young permanent teeth depends on the proper selection of dressing materials. This study aimed to evaluate the histological and histomorphometric response of dentin–pulp complex to the enamel matrix derivative (Emdogain® gel compared to that of calcium hydroxide when used as a pulp dressing in immature young permanent dogs’ teeth. Dentin-like tissues bridging the full width of the coronal pulp at the interface between the injured and healthy pulp tissues were seen after 1 month in both groups. With time, the dentin bridge increased in thickness for calcium hydroxide but disintegrated and fully disappeared for Emdogain-treated group. Progressive inflammation and total pulp degeneration were only evident with Emdogain-treated group. The root apices of Emdogain-treated teeth became matured and closed by cementum that attached to new alveolar bone by a well-oriented periodontal ligament. In young permanent dentition, Emdogain could be a good candidate for periodontium but not dentino–pulpal complex regeneration.

    To identify and quantify the variables and their influence on postoperative morbidity in dental treatment under general anesthesia (GA) in pediatric patients with and without an underlying disease. A prospective, descriptive, and comparative analysis was conducted of healthy (n = 49) and disabled/medically compromised (n = 81) children treated under GA. Intra-/post-surgical, clinical epidemiology, technical, care-related, and pharmacologic data were gathered, as were postoperative complications. The average age of ASA I patients (6.7 ± 4.4 years) was younger than that of ASA II-III patients (9.0 ± 4.5 years). Average hospitalization time was 4.27 ± 6.5 h in ASA I and 7.41 ± 6.8 h in ASA II-III. Significant differences were found between the two groups in fillings, pulpotomies, oral surgery, and scaling. Postoperative morbidity in ASA I and ASA II-III was similar both in frequency and severity and decreased during the first 72 h. The most common complication in both groups was toothache. Postoperative morbidity is high after dental treatment under GA, but it is not higher in disabled/medically compromised patients. © 2015 BSPD, IAPD and John Wiley & Sons A/S.

    Full Text Available Portland cement (PC is a hydraulic binding material widely used in the building industry. The main interest in its use in dentistry is focused on a possible alternative to mineral trioxide aggregate (MTA because PC is less expensive and is widely available. In dentistry, PC has been used in dental procedures such as pulpotomy, pulp capping, repair of root perforation and root-end filling. The purpose of this article is review the dental literature about the PC, its composition with special attention to arsenic content, properties, and application in dentistry. A bibliographic research was performed in Bireme, PubMed, LILACS and Scopus data bases looking for national and international studies about the PC composition, properties and clinical use. It was observed that PC has favorable biological properties very similar to those of MTA. The PC has shown good cell proliferation induction with formation of a monolayer cell, satisfactory inflammatory response, inhibitory effect of prostaglandin and antimicrobial effect. Studies have shown that PC is not cytotoxic, stimulates the apposition of reparative dentin and permits cellular attachment and growth. Regarding arsenic presence, its levels and release are low. PC has physical, chemical and biological properties similar to MTA. Arsenic levels and release are low, therefore, unable to cause toxic effects.

    Full Text Available Background/Aim. There are very few data about the effects of endogenous growth factors in vital pulp therapy, and still they are often controversial. The aim of the study was to evaluate the effects of platelet rich plasma (PRP in conjugation with hydroxyapatite (HAP, as pulp capping materials, to root and periodontium formation. Methods. Eight young monkeys (Cercopithecus Aethiops with permanent dentition and incomplete root formation were involved in this study. After pulpotomy, the pulp lesion was capped with calcium hydroxide (control, hydroxyapatite (experimental group I or hydroxyapatite in conjugation with PRP (experimental group II. Six months later, the animals were sacrificed, the tissue was removed en block, and prepared for the histological analysis in a routine way. Results. The results of the histological analysis revealed that healing process was characterised by dentin bridge formation, maintained morphological and functional integrity of dental pulp and complete formation of dental root and surrounding periodontium. The inflammatory reaction was scored as mild to moderate, in almost all the samples in all groups, suggesting the biocompatibility of the used materials. Conclusion. Materials used in this study are convenient as capping agents, contributing maintaining the integrity of the pulp tissue and facilitating root and periodontium formation. According to histological data it could be suggested that hydroxyapatite in conjugation with endogenous growth factors, represents superior alternative to other materials used in this study.

    The aim of this study was to evaluate the immunolocalization of dentin matrix protein (DMP)-1 in human primary teeth treated with different pulp capping materials. Twenty-five primary molars were divided into the following groups: formocresol (FC), calcium hydroxide (CH), mineral trioxide aggregate (MTA), corticosteroid/antibiotic solution + CH (O + CH), and Portland cement (PC), and all received conventional pulpotomy treatment. The teeth at the regular exfoliation period were extracted for histological analysis and immunolocalization of DMP-1. Statistical analysis was performed using the χ(2) test (p < 0.05). Histological analysis revealed statistically significant differences in the comparison among the groups through the use of a score system regarding the presence of hard tissue barrier, odontoblastic layer, and internal resorption, but not regarding pulp calcification. Immunohistochemical analysis showed immunostaining for DMP-1 in groups CH, MTA, O + CH, and PC. Internal resorption was observed in the groups FC and CH. MTA and PC showed pulp repair without inflammation and with the presence of hard tissue barrier. DMP-1 immunostaining was higher for MTA and PC, confirming the reparative and bioinductive capacity of these materials.

    Full Text Available Complicated crown fracture and crown-root fracture with pulp involvement expose dental pulp to the oral environment. The pulp outcome is often unpredictable because the patient and injury which are related to variables can influence the treatment of choice and the prognosis of the case. This report presents the case of a 4-year-old boy with complicated crown fracture with pulp polyp in the primary right maxillary central incisor (51 and crown-root fracture with pulp involvement in the primary left maxillary central incisor (61, which was treated only 3 months after the tooth injuries. The treatment of choice was extraction of tooth (61 due to a periapical lesion with disruption of the dental follicle of the permanent successor and pulpotomy (MTA of the tooth (51, because the pulp presented signs of vitality. At the follow-up visits, no clinical, symptomalogical, and radiographic changes were observed until the primary tooth’s exfoliation. However, at 3-year follow-up, the permanent successors showed hypocalcification and the position of the permanent right maxillary central incisors (11 was altered. Besides the conservative and adequate delayed treatment, the sequelae on the permanent successors could not be avoided.

    (1) To present a narrative review of the currently available alternative interventions and materials to formocresol pulpotomy for the management of extensive caries in the primary molar, and (2) to produce a clinical protocol for pulp therapy techniques in the extensively carious primary molar. The International Agency for Research on Cancer has recently classified formaldehyde as carcinogenic to human beings. Since Buckley's Formocresol contains 19% formaldehyde in its full strength and, therefore, 1% in a 20% dilution, a safer alternative should be identified. A narrative review of the published literature for primary molar pulp therapy techniques was undertaken following an extensive and appropriate literature search. A specialist group of paediatric dentists was formed to arrive at a consensus and establish an evidence-based protocol for the management of extensively carious primary molar teeth. Part I of this paper explores the currently available alternative interventions and materials to formocresol in the form of a narrative review. The second part of the paper will present the formation of a specialist group to arrive at a consensus and establish an evidence-based protocol for the management of the extensively carious primary molar. After consideration of a review of extensively searched literature, a protocol and key points document have been developed to assist clinicians in their treatment planning. Further long-term studies with the highest level of evidence (i.e. randomized controlled trials) are required to enable us to identify acceptable alternatives which can replace formocresol.

    It has been observed that the general dentists and pedodontists differ in their treatment recommendations for pulp therapy in deciduous teeth. To determine the knowledge and practice of pulp therapy in deciduous teeth by general dental practitioners (GDP) in two cities of southern Saudi Arabia. Fifty GDP selected at random from government and private dental clinics were questioned about pulp therapy in deciduous teeth in Abha and Najran cities using a 10-item questionnaire. The data were analyzed using IBM SPSS software version 11.0 and descriptive statistics were obtained. All 50 participants responded to the survey. Pulpotomy was suggested as the first line of treatment for pulp-exposed primary tooth by 32 respondents with 44 using Buckley's formocresol and 32 applying it on the pulp for 5 minutes. 43 respondents squeeze dried the cotton pellet before application on the pulp. In pulpectomy procedure 44 respondents preferred zinc oxide eugenol as obturation material with 22 using handheld reamers and 15 using slow-speed lentilospirals for obturation. 12 respondents used obturation techniques which had no scientific relevance. In order of preference Glass ionomer cement (GIC), silver amalgam, and stainless steel crowns were the materials of choice for final restoration of endodontically treated deciduous teeth. All 50 answered in the affirmative when asked if they would like to have additional information about pulp therapy in deciduous teeth. The study concluded that general dentists were regularly performing pulp therapy in decidous teeth and therefore need to be frequently updated about these procedures.

    This study investigates the profile of teaching primary tooth pulp therapy practiced by Brazilian dental schools. A multiple-choice questionnaire was sent by e-mail to 191 dental schools in Brazil, addressed to the pediatric dentistry Chairperson. The two-part survey consisting of multiple-choice questions regarding specific materials and techniques on pulp therapies, moreover, hypothetical clinical scenarios were presented so that the respondents could guide the treatment approach. The questionnaires were returned by 46.5% of the dental schools. Ninety-five percent of surveyed schools teach IPT for the treatment of deep carious lesions in dentin and indicate the calcium hydroxide as capping material (59.3%). The direct pulp capping is taught by 68.7% of schools and calcium hydroxide (97%) was the capping material most indicated. Pulpotomy is taught in 98.7% of schools and formocresol (1:5 dilution) was the medicament of choice (50%). All schools taught pulpectomy and Iodoform paste was the filling material preferred (55%). The results showed a lack of consensus in certain modalities and techniques for primary tooth pulp therapy taught by Brazilian dental schools.

    Purpose The purpose of this multisite, multioperator, prospective, randomized, controlled clinical trial was to evaluate the 6-month outcomes of diluted formocresol (DFC) compared to gray mineral trioxide aggregate (GMTA) as pulpotomy medicament. Methods Determined by a power analysis, 252 molars of 152 children were recruited. The teeth were randomly assigned to receive GMTA or DFC. At the 6-month follow-up, 118 children with 203 treated teeth were evaluated. Results Four blinded and calibrated evaluators scored each radiograph for pathologies. Clinical success was similar for DFC (97%) and GMTA (100%), (P<.09). Radiographic success differed significantly (P<.04) for DFC (86%) and GMTA (95%). Pulp canal obliteration was radiographically observed in 25% of the DFC group and in 37% of the GMTA group (P=.07). Dentin bridging was observed in 22% of the GMTA group but was not found in the DFC group (P<.01). Conclusion Teeth treated with GMTA showed more favorable radiographic outcomes than DFC at 6 months post-treatment. PMID:21070705

    Full Text Available Statement of Problem: One of the most challenging procedural accidents during pulpotomy of primary molars is furcal perforation. To prevent bacterial invasion, the perforation site should be sealed as soon as possible. Purpose: The aim of the current study is to investigate the ability of the pro- root MTA and new endodontic cement (NEC in repairing the furcation perforations of primary molar teeth. Materials and Method: In this in vitro study, 42 extracted primary molars were select-ed. Their roots were sectioned horizontally and standard access cavity was prepared. The orifices and the root apices were sealed with two layers of resin composite .The samples were randomly assigned into 2 groups. Six teeth were considered as the positive and the negative controls. In the experimental groups; perforation was made. In group 1 and 2, perforation site received pro- root MTA and NEC respectively. The teeth were covered by two layers of nail polish except for the external surface of the perforation site. The negative control group received no repairing material. All teeth were mounted and sterilized for 24 hours. Lower chambers were filled with sterilized Muller Hinton broth. Bacterial suspension of E-faecalis in 0.5 McFarland was prepared. Then repaired site was exposed to the bacterial suspension of E-faecalis every 3 days. All samples were inserted in an incubator at 37oC and 100% humidity. The turbidity of the samples was detected for a period of 30 days. Data were analyzed by Chi- square test. Results: 44% of samples in Pro- root group, 50% of the samples in the NEC group showed contaminations during 30 days. There was no significant difference between these two groups (p= 0.799. Conclusion: With limitations of this study, Pro- root MTA and NEC showed similar capability in sealing the furcal perforations of the primary molars.

    Full Text Available Objective: Zinc oxide eugenol (ZOE under composite restorations should be covered with a suitable material in order to prevent the harmful effect of ZOE on the composite. The aim of this in vitro study was to evaluate microleakage of composite restorations in pulpotomized primary molars with different bases for covering the ZOE layer and to assess the distance between different layers.Materials and Methods: Proximo-occlusal cavities were prepared in 78 extracted second primary molars. Carious lesions were removed and pulpotomy was carried out. Zinc oxide eugenol paste was placed in 2-mm thickness. The teeth were randomly divided in 6 groups and restored as follows: 1. Light-cured composite; 2. Resin-modified glass-ionomer and composite resin; 3. Glass-ionomer and composite resin; 4. Light-cured calcium hydroxide and composite resin; 5.Calcium hydroxide and composite resin; 6. Amalgam and composite resin. The restored specimens were thermocycled for 500 cycles (5°C/55°C and microleakage was assessed by dye penetration technique. Three specimens from each group were processed for scanning electron microscope evaluation to determine the distance between the layers. The results were analyzed by Kruskal-Wallis and Dunn tests.Results: Microleakage assessment revealed significant differences between the groups (P=0.04, with the amalgam group exhibiting the lowest microleakage values. In SEM micrographs no significant differences were observed in the distance between ZOE base layers (P=0.94 and base-composite layers (P=0.47; however, the amalgam group had the lowest distances.Conclusion: The use of amalgam over zinc oxide eugenol layer in pulpotomized primary molars decreases microleakage.

    Full Text Available Background: The most common technique to anesthetize mandibular primary teeth is inferior alveolar (I.A nerve block injection which induces a relatively sustained anesthesia and in turn may potentially traumatize soft-tissues. Therefore, the need of having an alternative technique of anesthesia with a shorter term but the same efficacy is reasonable. The aim of this study was a comparison of the efficacy of two anesthetic techniques of mandibular primary first molar. Materials and Methods: In this randomized crossover clinical trial, 40 children with ages ranged from 5 years to 8 years whose mandibular primary first molars were eligible for pulpotomy, were selected and divided randomly into two groups. The right and left mandibular first molars of group A were anesthetized with infiltration and I. A nerve block techniques in the first and second sessions respectively. The left and right mandibular first molars of group B were anesthetized with I.A nerve block and infiltration techniques in the first and second sessions respectively. The severity of pain were measured and recorded according to sound-eye-motor scale by a certain person. Data was analyzed using Wilcoxon Signed Rank and Mann-Whitney U tests (P < 0.05. Results: The severity of pain was lower in infiltration technique versus I.A nerve block. There were no significant differences between the severities of pain on pulpal exposure of two techniques. Conclusion: It seems that infiltration technique is more favorable to anesthetize the mandibular primary first molar compared to I.A nerve block.

    Full Text Available This comprehensive community health intervention aimed to improve the oral health and reduce the incidence of dental caries in Tabuk schoolchildren. The program supports the public health pyramid that provides a framework to improve health and included creating and evaluating a school oral health surveillance system, applying fluoride varnish and dental sealants on high- and medium-caries risk children, and providing treatment for existing diseases. In a pilot phase, 48 children (26 males 22 females; mean age 6.42; dmft 9.33, Decayed, Missing, or Filled Primary and Permanent Teeth (DMFT 3.27 received the dental services, both treatment and prevention. Three hundred seventy-eight composite resin or resin-modified light-cured glass ionomer restorations were placed. One-hundred and eighteen teeth received pulp therapy (pulpotomy or pulpectomy, ten of which received stainless steel crowns. A total of 72 teeth were extracted due to caries. To understand the effects of dental disease on children, as perceived by parents, an oral health-related quality of life survey was completed and analyzed. Results found an underestimation of the role the teeth play, particularly primary teeth, in the general health and wellbeing of the child. The program’s main evaluation effort focused on the process and outcome objectives, including the number of children received care, number of teeth received restorations and sealants, and number of children received fluoride varnish, etc. Analyzing the effect of the program on oral hygiene revealed an improvement in oral health, as a direct result of oral health educational sessions and one-to-one counseling. There is an urgent need to expand the program to include all primary schools.

    Full Text Available Background and the purpose of the study: Midazolam is preferably used in pediatric dentistry for quick onset of action and recovery. The aim of this prospective, observer-blind and placebo-controlled study was to assess the efficacy of a low dose of oral midazolam in modification of  the behavior of young pediatric dental patients. Methods: Forty children aged 3 to 5 years who displayed ratings 1 or 2 on the Frankl Scale and  were healthy by the American Society of Anesthesiologists-I status were randomly divided into two experimental and control groups of 20 each. All children required pulpotomy and restoration of D and E teeth and received either 0.25mg/kg of a 15mg/3ml IV midazolam mixed in black cherry syrup or the syrup alone. Subjects were continuously observed and monitored with pulse oximetry. Houpt's Behavioral Ratings was used to determine the overall behavior, the degree of crying and movement during treatment. Mann-Whitney U test was used for statistical analysis. Results and major conclusion: Patients who received 0.25mg/kg of the prepared oral midazolam significantly behaved better during treatment than the placebo controls (P<0.05. In comparison with the placebo group, reduced movement and crying were observed in the midazolam group (P<0.05. No adverse effects were observed and treatments were completed successfully. A low dose of 0.25mg/kg of a 15mg/3ml IV midazolam mixed in black cherry syrup was found to be effective in conscious sedation of young pediatric dental patients.

  1. Depth and activity of carious lesions as indicators for the regenerative potential of dental pulp after intervention.

    Studies on dental regeneration involving interventions for pulp therapy such as regeneration and revascularization procedures are promising for the injured tooth; however, a complete replication of the original pulp tissue does not seem to take place. In cases in which we wish to preserve or maintain parts of the pulp during treatment, it is apparent that the effectiveness of healing or biological regeneration is dependent on the degree of inflammation of the pulp tissue. Thus, the control or prevention of a pulp infection is still a major issue for the clinicians. Data indicate that the typical reason for performing endodontic treatment is deep caries. The biological concept of vital pulp therapy associated with deep caries takes the treatment and evaluation of the unexposed as well as the exposed pulp into account. Interestingly, the clinical diagnosis is typically the same. Deep caries with reversible pulpitis may receive differing treatments such as excavation procedures aiming to avoid pulp exposure or more pulp invasive treatments such as pulp capping or pulpotomy. This should not be the case. Consequently, huge treatment variation is noted among clinicians based on the same caries diagnosis. Which treatment should be selected? High-quality trials are needed, and it is important to obtain information on the actual lesion depth and an estimate of the lesion activity before treatment. These may be basic indicators for the regenerative potential of dental pulp. Recent clinical trials dealing with the treatment of deep caries lesion are discussed, including pulp invasive and noninvasive concepts, to attempt to solve the task of getting the best clinical outcome for adult patients.

    Tricalcium silicate cements can be used for pulp capping, pulpotomies, apical barrier formation in teeth with open apices, repair of root perforations, regenerative endodontics, and root canal filling. The aim of this study was to evaluate and compare the discoloration potential of 3 different tricalcium cements using a bovine tooth model. Forty bovine anterior teeth have been used for the study. Crowns separated from the roots were randomly divided into 4 groups: the BioAggregate (IBC, Vancouver, Canada) group, the Biodentine (Septodont, Saint Maur des Fosses, France) group, the mineral trioxide aggregate Angelus (Angelus, Londrina, PR, Brazil) group, and the only blood group. Materials have been placed to the standardized cavities on the lingual surfaces of the crowns, and their contact with blood has been provided. The color values of the samples were measured with a digital tooth shade determinator (VITA Easyshade; VITA Zahnfabrik, Bad Sackingen, Germany) before the placement of the materials, after the placement of the materials, in the 24th hour, in the first week, in the first month, in the third month, and in the first year. The mean value of all groups was compared using the Tukey multiple comparison test (α = 0.05). All groups displayed increasing discoloration during a period of the first year. The "only blood group" showed the highest color change values, and it was followed as BioAggregate, mineral trioxide aggregate Angelus, and Biodentine, respectively. Statistically significant differences were found for Biodentine when compared with the only blood and BioAggregate groups (P Biodentine is found to have the least discoloration potential among the tested materials.

    Full Text Available Context: The extensive plaque formation on dental restorations may contribute to secondary caries or periodontal inflammation. Therefore, it is important to know how different types of dental restorations may prevent or promote the accumulation of microorganisms. Aims: The aim of this in vivo study was to evaluate the adhesion of Streptococcus mutans to preveneered and stainless steel crowns (SSCs and to evaluate the effects of these restorations on the gingival health and oral hygiene. Materials and Methods: Twenty patients (age 3-5 years were selected from the outpatient clinic of the pedodontics department, Faculty of Oral and Dental Medicine, Cairo University. The selected patients had (dmf index for primary dentition ≤4, including lower right and left first primary molars. Each tooth was pulpotomy-treated and restored with either type of crowns (split-mouth technique. Then, ten swabs from the buccal mucosa, preveneered crown, and SSC surfaces were taken from each patient. Also, the gingival index (GI and oral hygiene index (OHI-S were measured at different times during the study. Mitis Salivarius Bacitracin agar (MSBA was used as a selective medium for S. mutans growth. MSBA plates were taken in candle jar and incubated aerobically in 37°C for 48 h. Finally, bacteria were counted and expressed in colony forming unit (CFU. Results: After 1, 2, and 4 weeks, mucosa and crown swabs of preveneered crown showed statistically significant higher mean CFU counts than SSC. Through the whole study period, the two restorations revealed a statistically significant decrease in mean CFU counts. Also, there was a statistically significant positive (direct correlation between OHI-S, GI, and S. mutans counts on both restorations. Conclusions: The adhesion of S. mutans to preveneered crowns was higher than to SSC. Full mouth rehabilitation led to significant decrease in S. mutans count in the short term. An increase in S. mutans counts is associated with

    This study investigated the pulp response to a 15.5 percent ferric sulfate solution (FS) and a 20 percent dilution of formocresol (DFC) in pulpotomized primary teeth of baboons, after four and eight weeks. Pulpotomies were performed in seventy-nine primary teeth of 4 baboons. After coronal pulp resection, the pulp stumps were painted with ferric sulfate for fifteen seconds, in thirty-two teeth (group 1); in another thirty-two teeth, a cotton pellet moistened with dilution of formocresol was placed over the pulp stumps for five minutes, and removed (group 2). In fifteen teeth, IRM was placed directly over the pulp stumps after hemostasis (group 3--control). The teeth of all groups were sealed with IRM, and examined for inflammatory changes under a microscope by two blinded examiners. Seventy-seven teeth were assessed. Mild or no inflammation was found in 58 percent (18/31) of the teeth of group 1, in 48 percent (15/31) of those of group 2, and in 73 percent (11/15) of those of group 3. Severe inflammation was found in 35 percent (11/31) of group 1, 29 percent (9/31) of group 2, and in 7 percent (1/15) of group 3. No statistically significant difference between the three groups was observed for degree of inflammation, periradicular or interradicular abscess or inflammatory root resorption (chi-square p > 0.05). Dentin bridges were observed in 52 percent (16/31) of the teeth in group 1, 52 percent (16/31) of those of group 2, and in 73 percent (11/15) of those of group 3. No difference was found between the experimental and control groups for the presence of dentin bridge, (p > 0.05). Ferric sulfate produced pulp responses that compared favorably to those of diluted formocresol.

    Patil, Anand C.

    2016-01-01

    Background Mineral trioxide aggregate (MTA) is a biomaterial that has been investigated for endodontic applications. With the increased use of MTA in pulp capping, pulpotomy, perforation repair, apexification and obturation, the material that would be placed over MTA as a final restoration is an important matter. As composite resins are one of the most widely used final restorative materials, this study was conducted to evaluate the shear bond strength of a composite resin to white mineral trioxide aggregate (WMTA) using three different bonding systems namely the two-step etch and rinse adhesive, the self-etching primer and the All-in-one system. Material and Methods Forty five specimens of white MTA (Angelus) were prepared and randomly divided into three groups of 15 specimens each depending on the bonding systems used respectively. In Group A, a Two-step etch and rinse adhesive or ‘total-etch adhesive’, Adper Single Bond 2 (3M/ESPE) and Filtek Z350 (3M ESPE, St Paul, MN) were placed over WMTA. In group B, a Two-step self-etching primer system, Clearfil SE Bond (Kuraray, Medical Inc) and Filtek Z350 were used. In Group C, an All-in-one system, G Bond (GC corporation, Tokyo, Japan) and Filtek Z350 were used. The shear bond strength was measured for all the specimens. The data obtained was subjected to One way Analysis of Variance (ANOVA) and Scheffe’s post hoc test. Results The results suggested that the Two-step etch and rinse adhesive when used to bond a composite resin to white MTA gave better bond strength values and the All-in-one exhibited the least bond strength values. Conclusions The placement of composite used with a Two-step etch and rinse adhesive over WMTA as a final restoration may be appropriate. Key words:Composite resins, dentin bonding agents, mineral trioxide aggregate, shear bond strength. PMID:27398177

    Deep caries presents a dilemma in terms of which treatment that will render an optimal prognosis by maintaining pulp vitality with absence of apical pathology. Previously, 2 randomized clinical trials were performed testing the short-term effects of stepwise carious tissue removal versus nonselective carious removal to hard dentin with or without pulp exposure. The aim of this article was to report the 5-y outcome on these previously treated patients having radiographically well-defined carious lesions extending into the pulpal quarter of the dentin but with a well-defined radiodense zone between the carious lesion and the pulp. In this long-term study, 239 of 314 (76.2%) patients were analyzed. The stepwise removal group had a significantly higher proportion of success (60.2%) at 5-y follow-up compared with the nonselective carious removal to hard dentin group (46.3%) ( P = 0.031) when pulp exposures per se were included as failures. Pulp exposure rate was significantly lower in the stepwise carious removal group (21.2% vs. 35.5%; P = 0.014). Irrespective of pulp exposure status, the difference (13.3%) was still significant when sustained pulp vitality without apical radiolucency and unbearable pain was considered (95% confidence interval, 3.1-26.3, P = 0.045). After pulp exposure, only 9% ( n = 4) of the analyzed patients were assessed as successful, indicating that the prognosis is highly dubious following conventional pulp-capping procedures (direct pulp capping or partial pulpotomy) in deep carious lesions in adults. In conclusion, the stepwise carious removal group had a significantly higher proportion of pulps with sustained vitality without apical radiolucency versus nonselective carious removal of deep carious lesions in adult teeth at 5-y follow-up ( ClinicalTrials.gov NCT00187837 and NCT00187850).

    Background: It has been observed that the general dentists and pedodontists differ in their treatment recommendations for pulp therapy in deciduous teeth. Aim: To determine the knowledge and practice of pulp therapy in deciduous teeth by general dental practitioners (GDP) in two cities of southern Saudi Arabia. Subjects and Methods: Fifty GDP selected at random from government and private dental clinics were questioned about pulp therapy in deciduous teeth in Abha and Najran cities using a 10-item questionnaire. The data were analyzed using IBM SPSS software version 11.0 and descriptive statistics were obtained. Results: All 50 participants responded to the survey. Pulpotomy was suggested as the first line of treatment for pulp-exposed primary tooth by 32 respondents with 44 using Buckley's formocresol and 32 applying it on the pulp for 5 minutes. 43 respondents squeeze dried the cotton pellet before application on the pulp. In pulpectomy procedure 44 respondents preferred zinc oxide eugenol as obturation material with 22 using handheld reamers and 15 using slow-speed lentilospirals for obturation. 12 respondents used obturation techniques which had no scientific relevance. In order of preference Glass ionomer cement (GIC), silver amalgam, and stainless steel crowns were the materials of choice for final restoration of endodontically treated deciduous teeth. All 50 answered in the affirmative when asked if they would like to have additional information about pulp therapy in deciduous teeth. Conclusion: The study concluded that general dentists were regularly performing pulp therapy in decidous teeth and therefore need to be frequently updated about these procedures. PMID:23440030

    Introduction: The aim of this study was to gather information on the materials and methods employed in root canal treatment (RCT) by general dental practitioners (GDPs) in Iran. Methods and Materials: A questionnaire was distributed among 450 dentists who attended the 53th Iranian Dental Association congress. Participants were asked to consider demographic variables and answer the questions regarding the materials and methods commonly used in RCT. Descriptive statistics were given as absolute frequencies and valid percentages. The chi-square test was used to investigate the influence of gender and the years of professional activity for the employed materials and techniques. Results: The response rate was 84.88%. The results showed that 61.5% of the participants did not perform pulp sensitivity tests prior to RCT. Less than half of the general dental practitioners (47.4%) said that they would trace a sinus tract before starting the treatment. Nearly 16% of practitioners preferred the rubber dam isolation method. Over 36% of the practitioners reported using formocresol for pulpotomy. The combined approach of working length (WL) radiographs and electronic apex locators was used by 35.2% of the practitioners. Most of the respondents used K-file hand instruments for canal preparation and the technique of choice was step-back (43.5%), while 40.1% of respondents used NiTi rotary files, mostly ProTaper and RaCe.

    The purpose of this study was to compare the effectiveness of an antibacterial and hemostatic agent to diode laser irradiation in the healing of mechanically exposed porcine pulps. The experiment required three adult swine (Sus scrofa domestica, Yorkshire) with 36 teeth prepared with occlusal penetrations into the pulpal tissues. The preparations were performed under general anesthesia and the pulps were exposed using high speed instrumentation with rubber dam isolation and a disinfected field. Following instrumentation the coronal pulpal tissue was amputated and immediately treated with ferric sulfate and chlorhexidine semi-gel (12), diluted Buckley' formocresol solution (12) for 5 minutes or laser irradiation with a diode laser (12). After treatment, hemostasis was obtained and a ZOE base applied to the treated pulps (36). The pulpal bases were all covered with a RMGI (Fuji II LC). The tissue samples were collected at 4 weeks (28 days). Following fixation, the samples were de-mineralized, sectioned, stained and histologically graded with a scale of 0-4. The treatment groups were statistically different with the Laser Treated Group demonstrating the least inflammation. Pulpotomy treatment with the KaVo Gentle Ray Diode Laser demonstrated significantly less inflammation than the other two pulpal therapy modalities. The ferric sulfate and chlorhexidine mixture demonstrated the greatest inflammation as histologically graded. Also, the histological sections of pulpotomized swine teeth treated with the ferric sulfate and chlorhexidine mixture presented with black pigmented areas in the pulp and surrounding tissue. The formocresol group (clinical standard) and the diode laser group did not present with the black precipitate.
