RESUMO
A natural irrigation solution with a broad spectrum of antimicrobial coverage, triphala was selected for the pulpectomy procedure. Because of its natural ingredients, it is well-known for promoting tissue healing. It also supposedly has certain additional qualities as compared to usual irrigation solutions that are made chemically. Although 2.5% NaOCl is thought to be perfect since it meets most of the requirements for an irrigation solution but it cannot be optimized for pulpectomy procedure. Primary teeth that were recommended for pulpectomy underwent this randomized controlled experiment. Two groups of eighty-four primary teeth were randomly assigned to receive irrigations: triphala in Group A; 2.5% Sodium hypochlorite in Group B. Sample were taken from infected primary root canals. A sterile test tube with bhi broth as the transport media was used to collect pre- and post-irrigation samples using sterile absorbent paper tips. On agar media, microorganisms were cultivated and their mean colony count was assessed. Following the procedure, the patient's follow-up visits at one, two and three months were used to evaluate the clinical result. The post-microbial colony count was dramatically reduced (p<0.001) by both irrigation treatments. Triphala in Group A is demonstrating desirable efficacy. Clinical success was found satisfactory in both the groups studied (p<0.001). But statistically significant difference was not found (p=0.175). Considering undesirable properties of sodium hypochlorite triphala can be a better alternative as a root canal irrigants in pulpectomy of primary teeth.

Introducción: Los dientes primarios juegan un importante papel en el crecimiento y desarrollo general de los niños, por lo que es necesario conservarlos hasta el momento de su recambio fisiológico. Cuando existe una afectación pulpar que compromete la vitalidad del diente, la pulpectomía se convierte en un reto para el odontopediatra debido a la compleja anatomía radicular de los dientes primarios. En esta revisión bibliográfica se darán a conocer diferentes sistemas de limas usados en odontopediatría, y así brindar una mirada actualizada de la instrumentación rotatoria al realizar pulpectomías en los molares primarios. Material y Método: se realizó una búsqueda bibliográfica en Pubmed y Web of Science de acuerdo con criterios de inclusión y exclusión previamente establecidos. Resultados: tras aplicar los criterios de inclusión y exclusión fueron seleccionados un total de 30 referencias bibliográficas de los últimos 15 años. Conclusión: las limas rotatorias pediátricas pueden considerarse alternativas seguras y más eficientes en la realización de pulpectomías en molares primarios, ya que se reduce el tiempo de tratamiento, se produce desbridamiento completo de los conductos y se mantiene la función del diente hasta su exfoliación.

Introduction: Primary teeth play an important role in the growth and development of children, so it is necessary to keep them until the moment of their physiological replacement. When there is a pulp involvement that compromises the vitality of the tooth, pulpectomy treatment becomes a challenge for the pediatric dentist due to the complex root anatomy of primary teeth. This review of the literature will present different file systems used in primary teeth and provide an updated look at rotary instrumentation when performing pulpectomies on primary molars. Material and Method: a bibliographic search was carried out in Pubmed and Web of Science according to previously established inclusion and exclusion criteria. Results: after applying the inclusion and exclusion criteria, a total of 30 bibliographic references from the last 15 years were selected. Conclusion: pediatric rotary files can be considered safe and more efficient alternatives in performing pulpectomies on primary molars, due to treatment time is reduced, complete debridement of the root canals is produced, and tooth function is maintained until exfoliation.

AIM: To compare the clinical and radiographically mixture of zinc oxide with Aloe vera, Curcumin and neem as an obturating material for pulpectomy. MATERIALS AND METHODS: The study comprised of age group 4-8 years children requiring endodontic treatment for at least a single primary molar tooth. Sixty primary molar teeth from 43 children were divided equally and randomly into four study groups. The materials used for obturation were zinc oxide powder (ZnO) and Eugenol (ZOE) (group I), ZnO and Aloe vera Gel (group II), ZnO and Curcumin Powder (group III), ZnO and neem extract (group IV). They were evaluated clinically and radiographically at immediate postoperative and then at 1-, 3-, 6-, and 9-month intervals. RESULTS: At the end of 9 months, the Chi-square test revealed 100% success rate for recovery of pain in group I and III, 66.66% in group II and 93.3% in group IV. The success rates for absence of abscess and for periradicular radiolucency in group I, III, and group IV were 100% and 66.6% for group II. The success rate for periapical radiolucency in group I and group III was 100%, in group II 66.6% and in group IV 93.35%. The success rate for all the groups shows 100% success in terms of pathological root resorption. CONCLUSION: Zinc oxide eugenol has proven to be the best obturating material. ZnO with Aloe vera showed a success rate which is significantly lower than the other medicaments. ZnO with Curcumin and ZnO with neem had shown promising clinical and radiographical results. CLINICAL SIGNIFICANCE: ZnO with Curcumin and ZnO with neem can be used as a root canal filling material in primary teeth with further follow-up studies.

AIMS: The aim of this study was to evaluation the treatment success of the short post technique (mushroom restoration) using a composite resin in severely decayed primary anterior teeth after 6, 12, and 18 months after treatment. METHODS: Eighteen children aged 3-5 years with severely decayed primary maxillary anterior teeth (60 anterior maxillary primary teeth in total) were included. Patients were treated under general anesthesia (GA). After pulpectomy, a "mushroom shape" was formed in the root canals for the purpose of retention, and the root canals were filled with zinc oxide-eugenol (ZOE), and the teeth were restored with composite resin. The status of treatment was evaluated clinically and radiographically for periapical radiolucency, pathological root resorption, marginal fracture, and loss of restoration for each treated tooth. All findings were recorded. RESULTS: As a result of the evaluation criteria, the success rates at 6, 12 and 18 months were 86%, 80%, and 71%, respectively. None of the teeth showed apical radiolucency or pathological root resorption at the end of the 18th month period. CONCLUSION: The short-post (mushroom restorations) technique is a clinically acceptable alternative method for restoration of severely decayed primary teeth. This study supports the feasibility of treatment with this technique for pediatric patients treated under GA.

This study indented to assess the clinical and radiographic assessment of Allium sativum extract as an intracanal irrigant for pulpectomy of primary molars. Ninety children with 110 teeth submitted were categorized into two groups. Clinical and radiographic success rates were checked at 3, 6, and 12 months. Qui-square test at a level of significance was Ë0.05. There was no statistically significant difference (p Ë .05) between the two groups that has not been detected clinically or radiographically. Clinical and radiographic success rates of garlic extract at 3 months were (80% and 72.7%), which declined at 6 and 12 months to be 76.4% 6 and 74.5% respectively. For NaOCl group, clinical and radiographic success rates were 87.3% and 85.5% at 3 months, 87.3% and 87.3% at 6 months and 89.1% and 87.3% at 12 months. A. sativum extract can be used efficiently as an irrigant for pulpectomy of primary molar root canals.

This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years old). A single trained operator performed the CT in a single visit in cases without periapical or interradicular radiolucency (PIR) or in multiple visits in cases with PIR. Participants were selected based on specific inclusion and exclusion criteria, and randomly allocated into two groups: Group 1 (G1) - iodoform paste (iodoform + camphorated parachlorophenol + ointment comprising prednisolone acetate 5.0 mg and rifamycin 1.5 mg); Group 2 (G2) - Calen®/ZO paste. Treated teeth were restored with composite resin immediately after the root canal filling. The outcomes were evaluated clinically and radiographically according to specific criteria. Two blinded and standardized evaluators assessed the radiographic outcomes. We used descriptive analyses due to the small sample size. CTs were performed due to caries lesions in 70.4% of the cases and due to trauma in 29.6%. Only one tooth of G1 was unsuccessful; hence, pulpectomy performance in both groups was not influenced by the filling material, nor by any other analyzed variable. The level of the root canal filling was better in the Calen®/ZO group. The clinical and radiographic twelve-month outcomes indicated successful treatment, independently of the root filling material used.

BACKGROUND: Complete pulpectomy and elimination of wide range of microorganisms from infected primary root canals is not possible through conventional endodontic procedures. Thus, lesion sterilization and tissue repair (LSTR) therapy employing 3Mix tri-antibiotic paste have been used as an alternative endodontic modality for infected primary teeth. AIM: This study aims to evaluate the root resorption rate of endodontically treated mandibular primary molars with conventional endodontic treatment or LSTR therapy and to compare it with their healthy contralateral teeth. MATERIALS AND METHODS: Fifty carious first and second primary mandibular molars from 25 healthy children aged 7-10 years were treated with two different endodontic procedures using LSTR Therapy and conventional endodontic treatment. The resorption rate of these teeth with healthy contralateral teeth was compared clinically and radiographically at 3, 6, 12 and 36 months using Chi-square test. RESULTS: At 12 months, clinically, there was no difference in the outcomes of both groups but radiographically, statistically significant difference (P < 0.001) in root resorption between treated teeth and their controls in both the groups was observed. At 36 months, interradicular bone resorption around the crown of succedaneous teeth and their delayed eruption was noted in LSTR group. CONCLUSIONS: LSTR therapy could be a viable treatment modality for infected/nonvital primary molars with poor prognosis and intended to be maintained for shorter duration in the oral cavity as natural space maintainers.

BACKGROUND: In children, dental caries (tooth decay) 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. Materials commonly used include mineral trioxide aggregate (MTA), calcium hydroxide, formocresol or ferric sulphate.This is an update of a Cochrane Review published in 2014 when insufficient evidence was found to clearly identify one superior pulpotomy medicament and technique. OBJECTIVES: To assess the effects of different pulp treatment techniques and associated medicaments for the treatment of extensive decay in primary teeth. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the Cochrane Oral Health Group's Trials Register (to 10 August 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2017, Issue 7), MEDLINE Ovid (1946 to 10 August 2017), Embase Ovid (1980 to 10 August 2017) and the Web of Science (1945 to 10 August 2017). OpenGrey was searched for grey literature. The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing interventions that combined a pulp treatment technique with a medicament or device in children with extensive decay in the dental pulp of their primary teeth. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed 'Risk of bias'. We contacted authors of RCTs for additional information when 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 pair-wise meta-analyses using fixed-effect models. We assessed statistical heterogeneity by using I² coefficients. MAIN RESULTS: We included 40 new trials bringing the total to 87 included trials (7140 randomised teeth) for this update. All were small, single-centre trials (median number of randomised teeth = 68). All trials were assessed at unclear or high risk of bias.The 87 trials examined 125 different comparisons: 75 comparisons of different medicaments or techniques for pulpotomy; 25 comparisons of different medicaments for pulpectomy; four comparisons of pulpotomy and pulpectomy; and 21 comparisons of different medicaments for direct pulp capping.The proportion of clinical failures and radiological failures was low in all trials. In many trials, there were either no clinical failures or no radiographic failures in either study arm.For pulpotomy, we assessed three comparisons as providing moderate-quality evidence. Compared with formocresol, MTA reduced both clinical and radiological failures, with a statistically significant difference at 12 months for clinical failure and at six, 12 and 24 months for radiological failure (12 trials, 740 participants). Compared with calcium hydroxide, MTA reduced both clinical and radiological failures, with statistically significant differences for clinical failure at 12 and 24 months. MTA also appeared to reduce radiological failure at six, 12 and 24 months (four trials, 150 participants) (low-quality evidence). When comparing calcium hydroxide with formocresol, there was a statistically significant difference in favour of formocresol for clinical failure at six and 12 months and radiological failure at six, 12 and 24 months (six trials (one with no failures), 332 participants).Regarding pulpectomy, we found moderate-quality evidence for two comparisons. The comparison between Metapex and zinc oxide and eugenol (ZOE) paste was inconclusive, with no clear evidence of a difference between the interventions for failure at 6 or 12 months (two trials, 62 participants). Similarly inconclusive, there was no clear evidence of a difference in failure between Endoflas and ZOE (outcomes measured at 6 months; two trials, 80 participants). There was low-quality evidence of a difference in failure at 12 months that suggested ZOE paste may be better than Vitapex (calcium hydroxide/iodoform) paste (two trials, 161 participants).Regarding direct pulp capping, the small number of studies undertaking the same comparison limits any interpretation. We assessed the quality of the evidence as low or very low for all comparisons. One trial appeared to favour formocresol over calcium hydroxide; however, there are safety concerns about formocresol. AUTHORS' CONCLUSIONS: Pulp treatment for extensive decay in primary teeth is generally successful. Many included trials had no clinical or radiological failures in either trial arm, and the overall proportion of failures was low. Any future trials in this area would require a very large sample size and follow up of a minimum of one year.The evidence suggests MTA may be the most efficacious medicament to heal the root pulp after pulpotomy of a deciduous tooth. As MTA is relatively expensive, future research could be undertaken to confirm if Biodentine, enamel matrix derivative, laser treatment or Ankaferd Blood Stopper are acceptable second choices, and whether, where none of these treatments can be used, application of sodium hypochlorite is the safest option. Formocresol, though effective, has known concerns about toxicity.Regarding pulpectomy, there is no conclusive evidence that one medicament or technique is superior to another, and so the choice of medicament remains at the clinician's discretion. Research could be undertaken to confirm if ZOE paste is more effective than Vitapex and to evaluate other alternatives.Regarding direct pulp capping, the small number of studies and low quality of the evidence limited interpretation. Formocresol may be more successful than calcium hydroxide; however, given its toxicity, any future research should focus on alternatives.

AIM: The aim of the present study was to assess the knowledge and practice of, and attitudes toward, pulp therapy in deciduous dentition among pediatric dentists. METHODS: A cross-sectional, observational survey was conducted using a closed-ended, multiple-choice questionnaire evaluating the knowledge and practice of, and attitudes toward, pulp therapy in deciduous dentition, which was formulated and sent to 360 pediatric dentists across India. Descriptive statistics were done, followed by χ2 -test to test the association between years of experience and the questionnaire items. RESULTS: A total of 3.5% of pediatric dentists performed their treatment using a rubber dam in all cases; 30% preferred to use local anesthesia prior to indirect pulp therapy (IPT). Traditional indirect pulp capping was preferred to IPT, and only 48% of them believed in not removing it completely. Pulpotomy was preferred over IPT (70%) when there was a probability of pulp exposure following complete caries excavation. Calcium hydroxide, along with iodoform, was the material of choice for the obturation of primary teeth (73.5%). A stainless steel crown was placed after pulp therapy in the primary tooth (86.3%). Most dentists believed requested immediate and 3-month follow up. CONCLUSION: The survey helps in assessing whether our views or approaches are in line with recent trends.

This report describes 3 successful single-visit regenerative endodontic therapy cases using platelet-rich plasma (PRP) and Biodentine (Septodont, Saint Maurdes Fossés, France) for 3 immature mandibular molar teeth, all with necrotic pulp, in 2 children aged 8 years and 1 aged 9 years. Three teeth were separately diagnosed as having a necrotic pulp. After preparation of the access cavity under rubber dam isolation, the necrotic pulp was removed, and each canal was irrigated with 2.5% sodium hypochlorite, sterile saline, and 17% EDTA solutions. Freshly prepared PRP was injected into each canal up to the cementoenamel junction, and Biodentine was placed directly over the PRP clot. Each access cavity was then restored with composite resin. Follow-up clinical examinations revealed negative responses to cold and electric pulp tests. None of the treated teeth were sensitive to percussion or palpation. Radiographic examination showed continued thickening of root canal walls and apical closure of the root apex of each tooth. Single-visit regenerative endodontic therapy can be considered in necrotic and asymptomatic immature permanent teeth. PRP and Biodentine may serve as scaffold and barrier materials in regenerative endodontic procedures.

OBJECTIVES: Novel methods for preserving primary teeth can help to maintain their developmental, esthetic, and functional capabilities. The aim of this study was to assess the success of the repair of bony defects, caused by pre-treatment perforations, with a mixture of three antibiotics combined with simvastatin (3Mixtatin) compared to MTA in hopeless primary molars. STUDY DESIGN: In this randomized clinical trial, 80 teeth from 65 healthy children aged 3-6 years with interradicular or periapical root resorption and/or perforation in primary molars were treated either with 3Mixtatin or MTA before conventional pulpectomy and restoration. The subjects were followed up clinically and radiographically for 4, 6, 12 and 24 months after pulp treatment to evaluate and compare the healing process. The data were compared using chi-square test at a significance level of 0.05. RESULTS: By the end of 24 months in 3Mixtatin group, 31 (96.8%) teeth revealed no clinical signs or symptoms with arrested resorption progress in radiographs. In MTA group, clinical signs and symptoms including pain, mobility and sinus tract were observed in 18 (48.6%) teeth with cessation of root/interradicular radiolucency in 7 (18.9%) teeth without bone repair. CONCLUSIONS: Radiographic and clinical healing occurred more successfully following 3Mixtatin treatment compared to treatment with MTA, it may lead to a paradigm shift in the pulpal treatment of primary teeth in the future.

OBJECTIVE: The aim of this systematic review was to determine whether the smear layer (SL) removal procedure influences the outcome of root canal treatment. STUDY DESIGN: We performed a search on Pubmed, Scopus, ISI Web of Science, Cochrane Library, Lilacs and SIGLE. We included randomized controlled clinical trials (RCT), with clinical and radiographic outcomes, conducted on subjects who had undergone root canal therapy. The protocol differed only in the SL removal or maintenance procedure. We evaluated the papers for risk of bias according to the Cochrane assessment tool. RESULTS: A total of 1,983 articles were found, after removal of duplicates, 892 remained. We included two studies in this review. One study revealed a low risk of bias and a high success rate for the SL removal group compared to the non SL removal group (P = 0.04), while the other study had a high risk of bias and found no difference between the SL removal and non SL removal groups (P = 1.00). CONCLUSION: We concluded that the SL removal for root canal treatment of primary teeth with initial clinical signs and symptoms or pulpal necrotic status, could benefit the outcome, although further RCT should be performed to achieve evidence.

The extraction of teeth results in rapid bone resorption both vertically and horizontally in the first month. The loss of alveolar ridge reduces the chance of implant rehabilitation. The atraumatic extraction, implant placement in extraction socket, and an immediate prosthesis have been proposed as alternative therapies to maintain the volume and contours tissue and reduce time and cost of treatment. Thus, this paper aims to present a clinical case where the extraction was performed using interradicular septum as guide for pilot drill in postextractive implantology with implant placement and immediate provisionalization in a inferior molar. The advantages of this technique are to place the implant exactly in the center of the alveolar ridge, to mantain the edges of the alveolar ridge and reduce postextractive bone resorption, and has great advantages in final prosthetic rehabilitation.

BACKGROUND: 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. OBJECTIVES: To assess the effects of different pulp treatment techniques and associated medicaments for the treatment of extensive decay in primary teeth. SEARCH METHODS: 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. SELECTION CRITERIA: 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. DATA COLLECTION AND ANALYSIS: 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. MAIN RESULTS: We included 47 trials (3910 randomised teeth) compared to three trials in the previous version of the review published in 2003. All trials were single centre and small sized (median number of randomised teeth 68). Overall, the risk of bias was low in only one trial with all other trials being at unclear or high risk of bias. The overall quality of the evidence was low. The 47 trials examined 53 different comparisons: 25 comparisons between different medicaments/techniques for pulpotomy, 13 comparisons between different medicaments for pulpectomy, 13 comparisons between different medicaments for direct pulp capping and two comparisons between pulpotomy and pulpectomy. Regarding pulpotomy, 14 trials compared mineral trioxide aggregate (MTA) with formocresol (FC). MTA reduced both clinical and radiological failures at six, 12 and 24 months, although the difference was not statistically significant. MTA also showed favourable results for all secondary outcomes measured, although again, differences between MTA and FC were not statistically significant (with the exception of pathological root resorption at 24 months and dentine bridge formation at six months). MTA showed favourable results compared with calcium hydroxide (CH) (two trials) for all outcomes measured, but the differences were not statistically significant (with the exception of radiological failure at 12 months). When comparing MTA with ferric sulphate (FS) (three trials), MTA had statistically significantly fewer clinical, radiological and overall failures at 24 months. This difference was not shown at six or 12 months.FC was compared with CH in seven trials and with FS in seven trials. There was a statistically significant difference in favour of FC for clinical failure at six and 12 months, and radiological failure at six, 12 and 24 months. FC also showed favourable results for all secondary outcomes measured, although differences between FC and CH were not consistently statistically significant across time points. The comparisons between FC and FS showed no statistically significantly difference between the two medicaments for any outcome at any time point.For all other comparisons of medicaments used during pulpotomies, pulpectomies or direct pulp capping, the small numbers of studies and the inconsistency in results limits any interpretation. AUTHORS' CONCLUSIONS: We found no evidence to identify one superior pulpotomy medicament and technique clearly. Two medicaments may be preferable: MTA or FS. The cost of MTA may preclude its clinical use and therefore FS could be used in such situations. Regarding other comparisons for pulpectomies or direct pulp capping, the small numbers of studies undertaking the same comparison limits any interpretation.

INTRODUCTION: Pulp necrosis in immature teeth and the resulting periodontal apical inflammation negatively affect root formation. Resolvin E1 (RvE1) is a lipid-derived endogenous pro-resolution molecule that controls inflammation. The aim of this investigation was to evaluate the impact of RvE1 applied as an intracanal medication on root formation in nonvital immature teeth. METHODS: To arrest root development, pulpectomy was performed in the lower first molars of 4-week-old Wistar rats. After 3 weeks, irrigation with 2.5% sodium hypochlorite and 0.9% sterile saline was performed, and either a triple antibiotic paste (TAP) or RvE1 in saline was applied into the root canals. In the control group, access openings drilled into molars were left exposed to the oral environment. Root development and periapical repair were evaluated radiographically and histologically at 3 and 6 weeks after treatment. RESULTS: RvE1 reduced periapical lesion size compared with the control at 3 weeks, which was similar to TAP. Inflammatory response in the RvE1-treated group was markedly reduced compared with both TAP and control specimens. At 6 weeks, root development was observed in both groups, but RvE1 treatment produced less cellularity with more regular calcified tissue deposition. CONCLUSIONS: RvE1 and TAP had a positive impact on reducing inflammation and promoting root formation. RvE1 was more effective in reducing inflammation at earlier stages. RvE1 has potential to be used as root canal dressing to control inflammation in endodontically compromised teeth before complete root formation. Stability of RvE1 within the root canal and its delivery are issues to be addressed before its clinical use.

BACKGROUND: Pulp therapy for pulpally involved primary teeth continues to be a challenge to clinicians. One of the major areas of continued research is in the area of finding obturating materials to suit the specific properties of these teeth. Zinc oxide eugenol is used frequently in pulpectomy for the obturation of the primary teeth. AIMS: To evaluate clinically and radiographically a mixture of zinc oxide eugenol and aloe vera as an obturating material. MATERIALS AND METHODS: A total of 50 children, aged between 4 and 9 years, who were screened for unilateral or bilateral carious deciduous molars were studied. Out of these, 15 children were randomly selected for endodontic treatment. Obturation was done with a mixture of zinc oxide powder and aloe vera gel. Clinical and radiographic evaluation was done after 7 days, 1 month, 3 months, 6 months, and 9 months. The data were statistically analyzed. RESULTS AND CONCLUSION: Endodontic treatment using a mixture of zinc oxide powder and aloe vera gel in primary teeth has shown good clinical and radiographic success. A detailed observational study with longer follow-up will highlight the benefits of aloe vera in primary teeth as an obturating medium.

AIM: To evaluate the success rate of mixture of ozonated oil and zinc oxide as a primary teeth root filling material. STUDY DESIGN: Prospective randomised clinical study. METHODS: The study included 60 infected primary mandibular molars which were equally divided into study group (ozonated oil-ZnO) and control group (zinc oxide-eugenol). Pulpectomy procedure was performed and the children were followed at regular intervals. All the children were available for evaluation at the end of 12 months. The teeth were evaluated for success or failure based on clinical and radiographic criteria by a blinded investigator. STATISTICS: The proportional values were compared using χ(2) test. RESULTS: Clinical and radiographic evaluation suggested that teeth obturated with ozonated oil-zinc oxide demonstrated good success rate (93.3%) as compared to zinc oxide eugenol (63.3%). However, no statistically significant variation (p = 0.408) was observed between the groups. CONCLUSION: Ozonated oil-ZnO demonstrated a good clinical and radiographic success at 12 months follow-up and it can be considered as an alternative obturating material in infected primary teeth.

UNLABELLED: The objective of endodontic therapy is not just simple cleaning and filling of root canals, but successful treatment requires the establishment of a sufficient level of disinfection. AIM: To evaluate, in vivo, the antimicrobial and inflammatory/irritant potential of Propolis against mixed endodontic aerobic and anaerobic bacteria. METHOD: An in vivo randomized controlled trial was conducted in a group of 60 children aged 6-12 years presenting with an acute apical abscess of the maxillary primary molars. Fifteen children each were divided randomly into four groups where irrigation during pulpectomy was performed using either 2% chlorhexidine, 4% calcium hydroxide or 4% Dimethyl Sulfoxide (DMSO) extract of propolis with normal saline as the control irrigant. Microbiological samples were taken from the disto-buccal root canal before initiating the pulpectomy as well as after 3 days later and for mixed aerobic and anaerobic bacterial cultures. RESULTS: In all the four groups, a significant decrease in mean aerobic colony forming units (cfu) count was seen. Maximum change in anaerobic cfu count was seen with 2% chlorhexidine. CONCLUSIONS: Chlorhexidine proved to be superior antimicrobial agent against both endodontic aerobes and anaerobes. Calcium hydroxide was found to be least effective.

BACKGROUND: The effect of smear layer (SL) removal on primary tooth pulpectomy outcome has not been well elucidated. AIM: To determine the effect of SL removal on primary tooth pulpectomy outcome. METHODS: This is a double-blind, randomized, and controlled clinical trial. Forty-eight patients were randomly divided into SL removal (G1 = 40 teeth) or smear layer nonremoval (G2 = 42 teeth) groups. Following the chemomechanical preparation with K-files and 2.5% sodium hypochlorite (NaOCl), teeth were irrigated with either 6% citric acid and 0.9% physiologic solution (G1) or only 0.9% physiologic solution (G2). Camphorated paramonochlorophenol was used as intracanal medication. At the second appointment, 1 week after, root canals were filled with zinc oxide-eugenol paste. Clinical and radiographical baseline criteria were stipulated equally for both groups. RESULTS: The success rate (G1 = 91.2%; G2 = 70.0%) was statistically different (P = 0.04) between the groups. In G2, the outcome was affected significantly by pulpal necrosis (P = 0.02), pre-operatory symptoms (P = 0.02), and periapical/inter-radicular radiolucency (P = 0.04). CONCLUSION: The pulpectomy outcome was improved by smear layer removal. The outcome for teeth with pulpal necrosis, pre-operatory symptoms, or periapical/inter-radicular radiolucency was significantly improved by removal of the smear layer.
