Pulpotomy versus pulpectomy in the treatment of vital pulp exposure in primary incisors. A systematic review and meta-analysis.

ABSTRACT: Background: Early childhood caries is a serious public health problem. When caries extend to involve the pulp, various forms of pulp treatment are tried to stimulate tooth repair. Although pulpotomy is the treatment of choice for vital primary tooth pulp exposure but there is a trend among many dentists to perform pulpectomies in vital primary incisors. This study aimed to assess the effect of pulpotomy and pulpecomy in treatment of carious vital pulp exposure in primary incisors. Methods: We searched Pubmed and Cochrane library databases up to March, 2018, OpenGrey for grey literature and ClinicalTrials.gov for ongoing trials. Randomized controlled trials were included and assessed with Cochrane risk of bias tool . Primary outcomes were clinical failure and radiological failure. The effect sizes were calculated as risk ratios with 95%CI using the Mantel-Haenszel method. Results: Four trials were identified for qualitative assessment, only three trials were included in meta-analysis after exclusion of one trial due to its high risk of bias. The pooled results of the longest follow up period for clinical failure showed no statistically significant difference between pulpotomy and pulpectomy. The relative risk (RR) was e 2.69, 95% CI 0.76 to 9.58 for clinical failure. For radiographic failure, the sensitivity analysis showed RR 0.45, 95% CI 0.25 to 0.83 with a higher risk for radiographic failure in pulpectomy. The evidence was limited by the small number of trials included in the meta-analysis. Conclusions: Both pulpotomy and pulpectomy can be used successfully in the treatment of vital pulp exposure in primary incisors. Further high quality studies comparing between pulpotomy and pulpectomy in primary incisors with longer follow up period till exfoliation time are needed.

Project description:IntroductionECC (Early childhood caries) is very common in children. Because of the small size of primary anterior teeth, endodontic exposures occur early. Pulp tissue response after pulpotomy of primary anterior teeth by both MTA and Portland Cement is very important when pulp exposures occur in these teeth.AimThis study aimed to evaluate in vivo pulp tissue responses after the primary canines pulpotomy with either White Portland Cement (WPC) or White Mineral Trioxide Aggregate (WMTA), by histopathological analysis.Materials and methodsThe study included 30 primary canines in 21 healthy children aged 6-9 years old and it was classified into 2 groups according to the material. Group 1: included 15 teeth capped by White Portland Cement, and Group 2: included 15 teeth capped by white MTA. The dentine bridge formation, soft Tissue Organization, tissue fibrosis, formed dentin bridge thickness, pulp calcifications, hemorrhage in the pulp tissue, and deposition of new dentin on the inner surface of the dentin at 3 months periods were recorded.ResultsData were analyzed statistically; the Mann-Whitney U test was performed for the assessment of histopathological criteria. Descriptive statistics were performed for the analysis of participant properties. Histopathological analysis showed complete dentin bridge formation and normal soft tissue organization for both materials. Statistical analysis showed no significant differences in dentine bridge formation (P value = 0.213), soft Tissue Organization (P value = 0.339), tissue fibrosis (P value = 0.079), formed dentin bridge thickness (P value = 0.139), pulp calcifications (P value = 0.581), hemorrhage in the pulp tissue (P value = 0.117), and deposition of new dentin (P value = 0.097), during the observation period.ConclusionsWithin the limitation of the current study WPC was similar to WMTA in terms of histological criteria so PC may serve as a good alternative to MTA in primary teeth pulpotomy.

Project description:Treatment planning is key to clinical success. Permanent teeth diagnosed with "irreversible pulpitis" have long been implied to have an irreversibly damaged dental pulp that is beyond repair and warranting root canal treatment. However, newer clinical approaches such as pulpotomy, a minimally invasive and biologically based procedure have re-emerged to manage teeth with pulpitis. The primary aim of the study was to conduct a meta-analysis to comprehensively estimate the overall success rate of pulpotomy in permanent teeth with irreversible pulpitis as a result of carious pulp exposure. The secondary aim of the study was to investigate the effect of predictors such as symptoms, root apex development (closed versus open), and type of pulp capping material on the success rate of pulpotomy. Articles were searched using PubMed, Scopus, CENTRAL, and Web of Science databases, until January 2021. Outcomes were calculated by pooling the success rates with a random effect model. Comparison between the different subgroups was conducted using the z statistic test for proportion with significance set at alpha = 0.05. A total of 1,116 records were retrieved and 11 studies were included in the quantitative analysis. The pooled success rate for pulpotomy in teeth with irreversible pulpitis was 86% [95% CI: 0.76-0.92; I2 = 81.9%]. Additionally, prognostic indicators of success were evaluated. Stratification of teeth based on (1) symptoms demonstrated that teeth with symptomatic and asymptomatic irreversible pulpitis demonstrated success rate of 84% and 91% respectively, with no significant difference (p = 0.18) using z-score analysis; (2) open apex teeth demonstrated a significantly greater success rate (96%) compared to teeth with closed apex (83%) (p = 0.02), and (3) pulp capping materials demonstrated that Biodentine yielded significantly better success rates compared to Mineral Trioxide Aggregate (MTA), calcium hydroxide, and Calcium Enriched Mixture (CEM.) Collectively, this is the first meta-analytical study to determine the clinical outcome of pulpotomy for carious teeth with irreversible pulpitis and it's predictors for success. Moreover, we identify the stage of root development and type of biomaterial as predictors for success of pulpotomy.
