Comparative Evaluation of Different Endodontic Access Cavity Designs with Different Burs-An in vitro Experimental Insight into the Aspect of Fracture Resistance.

Introduction: In vitro fracture resistance of extracted mandibular molars treated with various access cavity designs, including traditional endodontic cavity (TradAC), conservative/contracted endodontic cavity (ConsAC), ninja endodontic cavity (UltraAC), truss endodontic cavity (TrussAC), caries-driven access cavity (CariesAC), and intact teeth, is the focus of this study. Materials and Methods: Six groups of 20 mandibular molars, totaling 120, were used in the investigation. While the other five groups underwent various access cavity preparations, chemomechanical preparation, and obturation procedures before being repaired with composite resin, Group 1 was left unaltered (the control). A 6 mm round head tip was used to apply the fracture force, which was measured in newtons, at a crosshead speed of 1 mm/min until fracture developed. Results: According to the current study, the intact control group had the maximum fracture resistance. The access cavity groups' mean values were maximum in CariesAC followed by ConsAC, TrussAC, UltraAC, and TraditonalAC respectively. Conclusion: While among the four minimally invasive designs, CariesAC showed a higher fracture resistance despite the results being statistically insignificant, TradAC had a significantly lower resistance than other conservative access cavity designs.

Comparative Evaluation of Different Apex Locators as a Diagnostic Tool to Detect Root Perforations: An In Vitro Study.

Aim: The purpose of this study was to determine how effectively four distinct apex locators could diagnose root perforations in terms of accuracy and repeatability. Materials and Methods: Eighty mandibular premolars with a single root were instrumented. The distal face of the root was perforated at both the apical and middle thirds, five millimeters from the apical terminus. K-files connected to apex locators were used for detection on teeth set in an alginate-filled box. Results: The current research showed that all four apex locators accurately detected root canal perforations. Conclusion: This study's findings show that all four apex locators were able to accurately and successfully identify root canal perforations.

Comparing Patient Outcomes for Teeth Treated with Traditional Root Canal Therapy Versus Pulpotomy: A Randomized Controlled Trial.

Background: Root canal therapy (RCT) and pulpotomy are two common treatment modalities for managing dental pulp infections, but their comparative effectiveness in terms of patient outcomes remains unclear. This root canal therapy (RCT) aimed to assess and compare patient outcomes between teeth treated with traditional RCT and pulpotomy. Materials and Methods: In this single-center RCT, a total of 120 patients presenting with symptomatic dental pulp infections were randomly assigned to either the RCT group or the pulpotomy group. The RCT group received conventional root canal treatment, which involved complete removal of infected pulp and obturation of the root canals. The pulpotomy group underwent a procedure where only the coronal pulp tissue was removed, followed by the placement of a medicament. Pain levels, infection resolution, and tooth survival were assessed at 6 months and 1 year posttreatment. Results: At the 6-month follow-up, patients in the RCT group reported significantly lower pain scores (2.5 ± 0.8) compared with the pulpotomy group (4.3 ± 1.2, P < 0.001). Infection resolution was also higher in the RCT group (92%) compared with the pulpotomy group (78%) at 6 months. Tooth survival rates at 1 year were significantly higher in the RCT group (95%) compared with the pulpotomy group (81%, P < 0.05). Conclusion: This RCT demonstrates that traditional RCT is superior to pulpotomy in terms of pain reduction, infection resolution, and tooth survival. Patients who underwent RCT experienced less pain, faster infection resolution, and better tooth survival rates compared with those who received pulpotomy. These findings support the use of RCT as the preferred treatment modality for dental pulp infections.

Clinical and Epidemiological Interventions for Monkeypox Management in Children: A Systematic Review.

This review aims to compile the available literature on monkeypox, identify risk factors for developing the disease, and recommend effective preventative methods to reduce the number of reported cases and fatalities in children and pregnant women. In seeking out pertinent studies on monkeypox virus in children and pregnant women, we searched the literature using the databases Cochrane Library, Google Scholar, PubMed, EMBASE, Web of Science, and Scopus up to 1st February 2023. This study analyzed data from case studies of monkeypox in children and pregnant women. Clinical data and test findings of monkeypox patients less than 18 years old and pregnant women were analyzed. The Newcastle-Ottawa Scale was used to do the quality evaluation. Our record examination spanned the years 1985 to 2023 and found 17 children and five pregnant female patients treated with monkeypox in various hospitals/community centers. Zaire, Gabon, Chicago, Sierra Leone, Central African Republic, Northern DR Congo, Liberia, Cameroon, the Democratic Republic of the Congo, the United Kingdom, the Netherlands, and Florida all contributed to the 14 studies analyzed. There were no studies identified for meta-analysis of selected case studies of hospitalized children and pregnant women who were diagnosed with monkeypox. The incidence, prevalence, clinical characteristics, diagnosis, management, prevention, vaccinations, infant care, and care for expectant mothers are all discussed in this systematic review of monkeypox in children. Our research findings may provide a foundation for further focused research and the development of related recommendations or guidelines.
