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.

Objective: The aim of this study was to compare the clinical and radiographic success rates of pulpotomy in primary molars using formocresol versus sodium hypochlorite.Methods:  Twenty-three children aged 4-9 years with at least two primary molars requiring pulpotomy were randomly allocated into two groups. All teeth received stainless steel crown after conventional pulpotomy procedure with either NaOCl or formocresol. Clinical and radiographic signs/symptoms were recorded at six and 12 months. Outcomes were statistically analyzed using Fisher’s exact test and Chi-squaretest.Results: Clinical success rates at 6 and 12-month follow-up in both groups was 100%. At 6-month follow-up, radiographic success rate for NaOCl and formocresol groups was 100%. At 12-month recalls, in NaOCl group, 20 teeth (87%) and in formocresol group, 21 teeth (91.3%) had radiographic success. No significant difference was found in the radiographic success rates at 12 months (P=1.00). Internal root resorption was the most common radiographic pathologic finding in both groups.Conclusion:Clinical and radiographic success rates in NaOCl group was comparable with formocresol group, so NaOCL can be suggested as an alternative for primary teeth pulpotomies. However further clinical studies with long-term follow-ups are needed.

ABSTRACT Introduction To assess the amount of debris extruded apically during instrumentation of distal canals of extracted primary molars by three instrument systems [ProTaper Universal (PTU), ProTaper NEXT (PTN), and self-adjusting file (SAF)] compared with conventional stainless steel hand K-files (HF, control). Materials and methods Primary mandibular molars (n = 120) with a single distal canal were selected and randomly divided into four groups (n = 30) for root canal instrumentation using group I, HF (to size 0.30/0.02 taper), group II, PTU (to size F3), group III, PTN (to size X3), and group IV, SAF. Debris extruded during instrumentation was collected in preweighed Eppendorf tubes, stored in an incubator at 70°C for 5 days and then weighed. Statistical analysis was performed by one-way analysis of variance (ANOVA), followed by Turkey's post hoc test (p = 0.05). Results All the groups resulted in extrusion of debris. There was statistically significant difference (p < 0.001) in the debris extrusion between the three groups: HF (0.00133 ± 0.00012), PTU (0.00109 ± 0.00005), PTN (0.00052 ± 0.00008), and SAF (0.00026 ± 0.00004). Conclusion Instrumentation with SAF resulted in the least debris extrusion when used for shaping root canals of primary molar teeth. Clinical significance Debris extrusion in primary teeth poses an adverse effect on the stem cells and may also alter the permanent dental germ. Debris extrusion is rarely reported for primary teeth and it is important for the clinician to know which endodontic instrumentation leads to less extrusion of debris.

ABSTRACT Introduction Chemomechanical caries removal (CMCR) is an effective method of caries removal especially for primary teeth as they cause less discomfort when compared with conventional caries removal. The most significant thing about caries removal is the elimination of cariogenic bacteria. This study compares the antibacterial activity of two CMCR gels. Materials and methods A total of 40 primary molar teeth with carious dentin were split along the long axis in a laboratory. Total viable count (TVC) was taken for the teeth before splitting as a measure of colony-forming units per milliliter (CFU/mL). Each half was treated with either Carisolv or Carie-Care CMCR gels. Clean dentin samples were evaluated for Streptococcus mutans (SM) and Lactobacillus acidophilus (LB) after removal of carious tissue using the caries removal gels using serial dilutions and incubating on specific agar plates. Results The results showed significant reduction in mean TVC after use of both the CMCR gels. Both gels reduced the CFU/mL of SM and LB to a significant level (p < 0.05). However, there was no significant difference between the antibacterial activities of the two CMCR gels. Conclusion The CMCR gels (Carisolv and Carie-Care) significantly reduced the residual TVC as well as SM and LB in carious primary dentin. Both CMCR gels had a similar antibacterial activity on the carious dentin of primary teeth. Clinical significance The CMCR gels tested have a significant antibacterial activity and can be effectively used for elimination of caries-causing bacteria in primary teeth.

ABSTRACT Aim Use of dental implants in edentulous patients has become a common treatment modality. Treatment of such implants requires radiographic evaluation, and in most cases several different imaging techniques are necessary in order to evaluate the height, width and the structure of bone at implant site. The aim of this study was to evaluate the influence of head orientation in linear measurement for implant planning in cone beam computed tomography (CBCT). Materials and methods In the present in vitro study, 11 human dry mandibles were used. The width and height of bone at the central, canine and molar teeth areas were measured on the left and right sides by using digital calipers (as gold standard) and on CBCT images with Reaxis option and no Reaxis. Data were analyzed with Statistical package for the social sciences (SPSS) 18, using pair t-test, Tukey test and intraclass correlation (ICC). Results Data were collected by evaluation of 11 skulls and 66 samples on the whole. There were no significant differences in bone width in any area in both Reaxis and no Reaxis option (p > 0.05). There were significant differences in bone height in the central (p = 0.005) and molar teeth areas (p = 0.010). The results did not show any significant differences between the observers (p = 0.329). Conclusion Using the Reaxis option does not affect the measurement of bone width, while use of this option can make a significant difference for height measurements.

Objective: The present study determined whether primary molar pulpotomies showed equal in vitro and clinical success when restored with sandwich restoration with a bulk-fill flowable composite (BFRBC) liner versus a stainless steel crown (SSC) restoration. Study design: Sixty extracted human primary second molars with proximo-occlusal cavities were selected for in vitro test. The specimens were randomly divided into three groups (n = 20) and restored with sandwich restoration with a BFRBC liner, composite (RBC) restoration and SSC. In addition, sixty teeth were selected from 20 children and each child had at least three primary molars (first and/or second primary molar) requiring pulpotomy. The patients were recalled for clinical and radiographic evaluation at approximately 6- and 12-month intervals. Results: The SSC restoration had significantly higher microleakage than the others. Although there was a significant difference between the RBC and the SSC (P = 0.02), the differences between the BFRBC and the RBC, as well as between the BFRBC and the SSC, were not statistically significant at the 12-month radiographic evaluation (P = 0.33 and P = 0.11, respectively). Conclusion: In laboratory conditions, sandwich restoration with BFRBC liner showed a superior seal margins of pulpotomized primary molars. Based clinical and radiographical evaluation, teeth treated with formocresol pulpotomy and restored with sandwich restoration with BFRBC liner were as successful as those restored with a SSC.

Aim: This experimental study in vitro aimed to compare the disinfection of the primary teeth root canals system using the rotary and reciprocating file system. Methodology: Forty-eight root canals from twenty-four primary molar teeth were contaminated with the standard strain of Enterococcus faecalis and randomically splitted into 4 groups (n=12). The Group PN comprised the root canals prepared with the ProTaperTM  Next rotary system. The Group WOG was defined by the usage of WaveOneTM Gold reciprocating system. The files from both systems were thermo mechanical processed. The Group PU used the ProTaperTM Universal system, with no thermic treatment, and the Group C (negative control) received no treatment. Samples from the root canals were collected with sterile paper points before and after its preparation, diluted and distributed in plates with Brain Heart Infusion (BHI) agar. The bacterial colonies were counted and the results were statistic analyzed by Wilcoxon and Kruskal-Wallis (Dunn) tests. Results: There was significant bacterial reduction using the systems (p>0,01). However, there was no significant difference among them (p<0,05) (PN=3.38; WOG=3.85; PU=3.26). Conclusion: Both systems (rotary and reciprocating) provide disinfectionon the primary molar teeth root canals system.

Purpose: The purpose of this study was to evaluate dentin mineral density before and after caries removal with the traditional caries removal technique and chemo-mechanical method, with or without the use of caries detection dye. Our null hypothesis was that the chemo-mechanical method with minimally invasive treatment would achieve an effect similar to that of conservative pediatric dentistry treatment. Materials & Methods: Forty-eight medium-sized, interfacial decayed primary molar teeth without pulpal perforation were selected. Two groups were formed by Papacarie Duo and conventional method; then four sub-groups were formed by two caries detection dye applied or not applied groups, twelve teeth were randomly divided into each group. The teeth were then treated with chemo mechanical and traditional caries removal approach. Teeth were scanned with the same voxel sizes using micro-computed tomography images to figure out the difference dentin mineral density and to calculate the removed dentinal volume after chemo-mechanical or traditional method application. Results: The results showed increase of cavity volume in the chemo-mechanical and traditional method groups. No significant difference was found for cavity volume and dentinal carious volume in both groups (p>0.05). The mineral density values of demineralized dentin were between 0.52-0.66 g/cm3 before caries removal, and 1.39-1.59 g/cm3 after removing caries. These values were found to be within the range of healthy dentin mineral density values again without any significant difference between groups (p>0.05). Conclusion: In conclusion, chemo-mechanical methods can be used effectively for removing the caries in the primary molar teeth similar to conservative treatments.

Irreversible Pulpitis

Background: When a tooth is diagnosed with irreversible pulpitis, root canal therapy (RCT) is generally performed to completely remove pulp tissue, which might lead to a higher risk of loss of vascularity, and teeth being more prone to fracture. Vital pulp therapy (VPT) is a personalized method of treating irreversible pulpitis, which conforms to the trend of minimally invasive endodontics. The remaining vital pulp could promote the physiological development of the roots of young permanent teeth with incomplete apical foramen. However, clear guidelines for VPT indication are still missing. Objective: This prospective cohort study evaluated the outcomes of vital pulp therapy (VPT) using iRoot BP Plus (Innovative Bioceramix Inc, Vancouver, BC, Canada) in permanent teeth of 6- to 20-year-old patients with irreversible pulpitis caused by caries and analyzed the preoperative factors affecting VPT prognosis. Methods: Fifty-nine permanent teeth in 59 patients with irreversible pulpitis caused by caries were treated with VPT using iRoot BP Plus. All patients received VPT under a standardized protocol. After informed consent, teeth were isolated with a dental dam, then operators performed VPT with iRoot BP Plus and restored the teeth with composite resin or stainless steel crown. Patients were postoperatively recalled after 3, 6 and 12 months and then recalled annually. Successful cases were defined as successful in both clinical and radiographic evaluations. A statistical analysis was performed using the Fisher exact test, and the level of significant difference was p < 0.05. Results: After 6–36 months of follow-up, a total of 57 teeth from 57 patients were accessible for evaluation. The mean age of subjects was 11.75 ± 3.81 years. The overall clinical and radiographic success rate of VPT was 91.2% (52/57). With an observation time of one year or more, the success rate was 90.5% (38/42). All the symptoms and physical examination findings showed no significant effect on VPT prognosis (p > 0.05) using a binary logistic regression model. Conclusions: Permanent teeth in 6- to 20-year-old patients diagnosed as irreversible pulpitis caused by caries can be successfully treated with VPT using iRoot BP Plus.

ABSTRACT Introduction 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. Aims 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. Materials and methods 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. Results 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. Conclusion Biodentine can be used as a pulpotomy agent but further long-term studies are required. How to cite this article Sirohi K, Marwaha M, Gupta A, Bansal K, Srivastava A.
