Indirect pulp therapy (IPT) is a common conservative treatment for deep dental caries. However, the potential risk factors for the prognosis of IPT have not been well studied. This study retrospectively investigated the success rate of IPT in treating primary molars with deep caries and the factors potentially affecting the two-year success rate. A total of 303 primary molars in 202 children (106 boys and 96 girls) were included in this study. These primary molars were identified as having deep caries by clinical and radiographic examinations and were treated with IPT. The factors potentially affecting the IPT success rate were analyzed after two years of follow-up. The results indicated that the two-year IPT success rate was 86% (262/303). The success rate of primary molars with and without stainless steel crowns was 96% (120/125) and 80% (142/178), respectively. Primary molars treated with stainless steel crowns showed a significantly lower risk of failure (hazard ratio (HR) = 0.18, 95% confidence interval (CI): (0.10, 0.34), p = 0.01). There were no significant differences in other factors, including gender (male vs. female), age (preschool vs. school age), cooperation level (Frankl 2 vs. 3 or 4 scales), arch type (maxillary vs. mandibular), tooth type (first vs. second primary molar), or pulp capping material (calcium hydroxide vs. glass ionomer cement). IPT is an effective, conservative treatment modality for primary molars with deep caries. Stainless steel crowns could significantly improve the IPT success rate.

OBJECTIVE: The study aimed to evaluate temporary fillings using Biodentine™ in asymptomatic deep carious lesions after 12, 24, and 36 months in school children from the remote village of Kerung, Nepal.
METHODS: From November 2018 to November 2019, 91 temporary fillings were placed using Biodentine™ (a hydraulic calcium silicate cement) in permanent molars with deep carious lesions of schoolchildren in the remote district of Kerung, Nepal. These restorations were performed after selective caries removal in a non-dental setting with hand instruments and cotton roll isolation, as electric motors and saliva ejection systems were unavailable. In total, 78 single-surface and 13 multi-surface fillings were placed. Clinical and radiographic follow-up periods encompassed 12, 21, and 33 months, respectively.
RESULTS: After 12 months, all single-surface fillings (100%) survived, whilst all multi-surface fillings were partially or entirely lost. The survival rate of single-surface restorations after 21 and 33 months was 67.6% and 50%, respectively. Radiographically, no pathology was observed.
CONCLUSIONS: This study showed that Biodentine could be used in deep carious lesions as a temporary filling in single-surface lesions for at least up to 1 year and in a substantial number of cases for up to 21 and 33 months.

To evaluate the impact of using ion-releasing liners on the 3-year clinical performance of posterior resin composite restorations after selective caries excavation with polymer burs. 20 patients were enrolled in this trial. Each patient had two deep carious lesions, one on each side of the mouth. After selective caries removal using polymer bur (PolyBur P1, Komet, Brasseler GmbH Co. KG, Lemgo, Germany), cavities were lined with bioactive ionic resin composite (Activa Bioactive Base/Liner, Pulpdent, Watertown, MA, USA) or resin-modified glass ionomer liner (Riva Light Cure, SDI, Bayswater, Victoria, Australia). All cavities were then restored with nanofilled resin composite (Filtek Z350XT, 3M Oral Care, St. Paul, MN, USA). All the tested materials were placed according to the manufacturers\' instructions. Clinical evaluation was accomplished using World Dental Federation (FDI) criteria at baseline and after 6 months, 1, 2, and 3 years. Data were analyzed using Mann-whitney U and Friedman tests (p < 0.05). The success rates were 100% for all resin composite restorations either lined with ion-releasing resin composite or resin-modified glass ionomer liner. Mann-whitney U test revealed that there were no statistically significant differences between both ion-releasing lining material groups for all criteria during the follow-up periods (p > 0.05). Resin composite restorations showed acceptable clinical performance over 3 years either lined with bioactive ionic or resin-modified glass ionomer liners after selective caries excavation preserving pulp vitality. After the 3-year follow-up period, Activa Bioactive and Riva Light Cure liners were clinically effective and they exhibited with the overlying composite restorations successful clinical performance.Trial registration number: NCT05470959.

UNASSIGNED: This non-randomized clinical trial investigated the outcomes of full pulpotomy in adult molars with irreversible pulpitis, comparing those with calcified and non-calcified pulp chambers over 6 and 12 months.
UNASSIGNED: A total of 101 adult permanent molars with irreversible pulpitis, in individuals over 12 years old, were categorized based on pulp chamber calcification observed in radiographic images by two endodontists. Subsequently, full pulpotomy procedures were performed, achieving hemostasis, and applying a 2 mm layer of calcium-enriched mixture (CEM) cement as a pulp covering agent. After 48 hours, the setting of the CEM cement was verified, followed by the application of a layer of resin-modified glass-ionomer. The tooth was then restored using amalgam. Clinical and radiographic evaluations were conducted at 6-month and 1-year follow-ups by blinded endodontists. Success rates were compared using Fisher\'s exact test and logistic regression tests with a significance level of 0.05.
UNASSIGNED: Among the 97 patients with 6-month and 1-year follow-ups, all achieved clinical success. Radiographic success rates were 99% at 6 months and 96.9% at 1 year, regardless of pulp calcification. In the 6-month follow-up, success rates were 98.07% for non-calcified pulp chambers and 100% for calcified pulp chambers. At the 1-year follow-up, success rates were 96.1% and 97.8%, respectively. Statistical analysis showed no significant difference in radiographic success rate between the two groups at both follow-ups (P>0.05).
UNASSIGNED: Full pulpotomy using CEM cement is a successful treatment for adult permanent teeth with calcified and non-calcified pulp chambers presenting signs and symptoms of irreversible pulpitis up to a 1-year follow-up. This study provides compelling evidence that vital pulp therapy can be effectively employed in the pulpotomy of calcified teeth, at least in the short term.

OBJECTIVE: This study aimed to compare the outcome of SCR and Pulpotomy in teeth with deep caries extending at least 75% into dentine.
METHODS: This two-armed, parallel-group, randomized, superiority trial included vital mature permanent teeth with deep primary or secondary caries diagnosed radiographically as being at least 75% into the thickness of dentine, without clinical signs of symptomatic irreversible pulpitis or radiographic evidence of a periapical lesion. Carious teeth were blindly allocated to receive either SCR or Pulpotomy using computer-generated randomized patient codes concealed in opaque envelopes. All teeth were reviewed clinically and radiographically at 6 months and 1 year post-treatment. Using a significance level of p < .05, the log rank test and Cox proportional hazards regression were used to compare the outcome of SCR and Pulpotomy and to identify potential prognostic factors, respectively.
RESULTS: In all, 58 teeth in the SCR group and 55 teeth in the pulpotomy group completed treatment, after excluding 6 teeth because they did not complete the allocated treatment and another due to severe periodontal disease. At one year, 57/58 (98.3%) teeth from the SCR group and 48/55 (87.3%) teeth from the Pulpotomy group were available for analysis. One tooth in the Pulpotomy group (2.1%) and eight teeth in the SCR group (14.0%) required the further intervention of root canal treatment (p < .05). There were no other significant prognostic factors for survival. Overall, 91.4% of teeth treated with either SCR or Pulpotomy survived without requiring further intervention over a period of one year. No other adverse events occurred over the review period.
CONCLUSIONS: Within the limitations of this study, Pulpotomy fares better than SCR in preserving the remaining pulp and periapical health. As a treatment modality, Pulpotomy carries greater cost outlay to patient and takes a longer time to complete treatment than SCR. Long-term follow-up is needed to study the pulpal and restorative outcomes of Pulpotomy and SCR.

OBJECTIVE: To assess the clinical and radiographic outcome of partial pulpotomy by comparing MTA Angelus and Total Fill BC, as pulpotomy agents, in mature teeth with deep caries and symptoms indicative of irreversible pulpitis.
METHODS: The study was designed as a parallel-two arm, double-blind, randomized superiority clinical trial registered at www.
RESULTS: gov (NCT04870398). Symptomatic mature permanent teeth with deep caries fulfilling the inclusion criteria were randomly treated using either MTA Angelus or Total Fill BC. A partial pulpotomy was performed and following complete haemostasis, the capping material was placed over the remaining pulp tissue and a postoperative periapical radiograph was taken. Clinical and radiographic follow-up evaluation was performed for a median time of 2 years, whereas levels of pain intensity were evaluated preoperatively and for 7 days after intervention using Visual Analogue Scale. For the primary outcome (failure/success of treatment), the Kaplan-Meier survival curves for the capping materials were plotted and a log-rank test for equality of survivor functions was applied. A multivariable random effects Cox Regression model was also applied. For the secondary outcome (postoperatively reported pain), a multivariable mixed effects ordinal logistic regression was structured.
RESULTS: One hundred and thirty-seven teeth in 123 patients underwent partial pulpotomy using randomly either MTA Angelus (N = 74) or Total Fill BC (n = 63). The percentage failure for MTA Angelus and Total Fill BC was 10.8% (8/74) and 17.5% (11/63), respectively, but the difference was not statistically significant [adjusted HR: 1.83; 95% confidence interval (CI): 0.68, 4.91; p = .23]. Weak evidence was found that secondary caries involvement may impose a 3.54 times greater hazard for treatment failure (adjusted HR: 3.54; 95% CI: 1.00, 12.51; p = .05). For each passing minute of procedural bleeding control, there was also a 57% higher hazard for treatment failure (adjusted HR: 1.57; 95% CI: 0.99, 2.48; p = .05). The odds for higher postoperative pain were 4.73 times greater for the Total Fill BC compared to MTA Angelus (adjusted OR: 4.73; 95% CI: 2.31, 9.66; p < .001).
CONCLUSIONS: Both materials exhibited similar and favourable outcome rates after partial pulpotomy in teeth with deep caries and symptoms of irreversible pulpitis. Total Fill BC was associated with a higher level of postoperative pain intensities.

UNASSIGNED: To assess and compare the treatment outcome of direct pulp capping with mineral trioxide aggregate (MTA) and Biodentine, after complete excavation of caries in permanent dentition with a 2-visit treatment protocol.
UNASSIGNED: Direct pulp capping with white MTA was performed in 70 teeth. Direct pulp capping with Biodentine was also done in 72 teeth. In the subsequent visits after 2 weeks, pulp sensibility tests were attempted in both studied groups. All clinical outcomes were categorized as success or failure.
UNASSIGNED: The success rate of the pulp capping procedure in the MTA group at the end of 12 months study was 94.3% in the Class I subgroup and 93.3% in the Class II subgroup.
UNASSIGNED: Direct pulp capping with MTA and Biodentine, after pulp exposure during excavation of deep caries could maintain pulp vitality in permanent teeth.

OBJECTIVE: To evaluate clinical and radiographic outcomes of vital pulp therapy (VPT) in deeply carious young permanent first molars (PFM) affected with MIH over 24 months.
METHODS: In this prospective randomized clinical trial, n = 50 children with deeply carious young PFM affected with MIH, and diagnosed with reversible or irreversible pulpitis were randomized into 2 groups: indirect pulp treatment (IPT) and pulpotomy (partial or complete). Teeth were followed up clinically and radiographically for 24 months. Statistical analysis was done using Chi-square test; P ≤ 0.05 was considered significant.
RESULTS: A total of  n = 50 teeth/patients (n = 26 females (52%), n = 24 males (48%)) were included, and 14 upper and 36 lower PFM were treated. Mean age was 11 ± 3.2 years. Clinical and radiographic success rates were: 96% for IPT, 90% for PP and 82% for CP (and 86% for both types of pulpotomy combined) over 24 months. There were no significant differences in outcomes between treatment groups. Age, gender and tooth location/jaw were found to have no statistically significant difference in outcomes among treatment groups, nor did pulpal status or root maturity, regardless of type of VPT and follow up period.
CONCLUSIONS: VPT is a valid treatment option in deeply carious young permanent first molars affected with MIH over 24 months. IPT had a higher clinical and radiographic success rate (96%) than partial or cervical pulpotomy (total 86%), but the difference was not statistically significant. Future randomized clinical trials on VPT for teeth affected with MIH are recommended with larger sample size and longer follow-up.

OBJECTIVE: To prospectively investigate the outcome of partial pulpotomy after 1 year, using a hydraulic calcium silicate cement (HCSC) on symptomatic cariously exposed pulps in adult teeth. To compare the traditional American Association of Endodontists (AAE) pulpitis classification with the recently proposed Wolters classification system in predicting the likelihood of treatment failure.
METHODS: Sixty-two symptomatic adult teeth with deep and extremely deep carious lesions were classified according to the Wolters (mild/moderate/severe pulpitis) and the traditional pulpitis classification (reversible/irreversible pulpitis). Eleven teeth were excluded intraoperatively as there was no pulp exposure after non-selective caries removal. The remaining 51 teeth, regardless of diagnosis, were treated by partial pulpotomy, pulpal lavage with 2.5% sodium hypochlorite solution, haemostasis and HCSC application (Biodentine™) as a pulp capping material. A permanent restoration was placed during a second appointment 1-2 weeks later. Preoperative tenderness to percussion (TTP), bleeding time and material setting time were recorded as was preoperative and postoperative tooth colour under standardized conditions. Clinical review occurred at regular intervals with clinical/radiographic analysis at 12 months. Chi-square analysis and Fisher\'s exact test assessed different outcomes amongst the diagnostic categories; the Kruskal-Wallis and Wilcoxon rank-sum test assessed influence of pulp bleeding time, TTP or variation in setting time (p < .05).
RESULTS: Ten cases were lost to review, and a total of 41 teeth were reviewed at 1 year and classified as either \"success,\" \"successful but unresponsive to sensibility testing\" or \"failed.\" This included five severe, 17 moderate and 19 mild pulpitis according to Wolters classification or 23 reversible pulpitis and 18 irreversible pulpitis cases by the AAE classification. The majority of the 62 enrolled cases were \"extremely deep\" (n = 50), rather than \"deep\" (n = 12) caries with all failures occurring in the extremely deep group. Partial pulpotomy was 90% successful (100% reversible, 78% irreversible or 100% mild, 88% moderate, 60% severe pulpitis) with a significant difference in outcome between mild and severe pulpitis groups (p = .04). Only one, severe pulpitis/irreversible pulpitis, case failed painfully prior to the 1-year review appointment. Bleeding time (p = .26) and TTP (p = .61) did not influence treatment outcome, whilst Biodentine™ setting time was significantly longer than manufacturers\' claim (p < .05). No teeth discoloured.
CONCLUSIONS: Partial pulpotomy using Biodentine™ was successful for treating symptomatic carious pulpal exposures after 1 year, but included cases where pulp vitality could not be confirmed. Within the limitations of this study, cases with signs and symptoms indicative of irreversible pulpitis were not less successful; however, Wolters classification highlighted severe pulpitis to be less successful than mild pulpitis, thereby providing a potential prognostic benefit in diagnostically subdividing pulpitis. Caries depth was an indicator of failure, whilst bleeding time and preoperative tenderness to percussion were not.

UNASSIGNED: To comparatively evaluate the clinical efficacy of stepwise caries excavation with indirect pulp capping (IPC) in managing the young permanent teeth in pediatric patients who have deep carious lesions.
UNASSIGNED: Eighty-eight teeth (first/second permanent molars) were included and randomly divided into two groups: group I (stepwise caries excavation) and group II (IPC). For group I, i.e., stepwise caries excavation, in the initial visit, bulk caries removal was done from walls of the cavity, however, soft and infected dentin was left untouched on the pulpal floor. The final excavation was performed after 2 months. The dentin parameters like the color, the consistency, and the humidity of dentin were noted at the first and second visits. A final follow-up to assess the primary outcome, i.e., sustained pulp vitality, was done after 1 year.
UNASSIGNED: When both the groups were compared with each other using the Chi-squared test, a highly significant difference was found (p < 0.05) between them. The success rate of stepwise caries excavation (97.3%) was found to be significantly greater than IPC (82.4%). After doing statistical analysis, a significant difference between stepwise excavation at baseline and at re-entry for parameters like the color, the consistency, and the humidity (p < 0.05), where dentin was observed to be darker in color, harder in consistency, and drier to touch at re-entry was found.
UNASSIGNED: Stepwise caries excavation was considered a safer technique than IPC for preserving the vitality of young permanent teeth. Also, the clinical changes recorded during the re-entry in the case of stepwise caries excavation technique indicated the arrest of the carious process.
UNASSIGNED: Pulp preservation is of utmost importance especially in the case of young permanent teeth which have open apex to aid in apexogenesis. Failure to do so in maintaining the vitality of pulp before root completion may lead to the unfavorable crown to root ratio resulting in thin dentinal walls which are prone to fracture.
