- Clinical efficiency of lasers in endodontic treatment of primary endodontic cases : an umbrella review of systematic reviewsPublication . Duarte, Marta Alves; Neves, João Albernaz; Caçador, Madalena; Flores-Fraile, JavierObjectives: To evaluate and synthesise the current evidence on the efficacy of laser-activated irrigation in endodontics, with a focus on microbial reduction, postoperative outcomes, and its potential as an adjunct to conventional irrigants. Method: A comprehensive search was conducted to identify relevant systematic reviews. A total of 319 systematic reviews were initially identified. After the removal of 116 duplicates, 203 records were screened. Of these, 22 systematic reviews met the eligibility criteria. However, reviews that included exclusively in vitro studies or were considered to have limited clinical relevance were excluded. Ultimately, 9 systematic reviews were included in this umbrella review, evaluating different laser systems such as Er:YAG, Er,Cr:YSGG, Nd:YAG, and diode lasers in the context of root canal irrigation. This review was registered at PROSPERO (CRD42025599352). For this umbrella review, 5 electronic databases (PubMed/MEDLINE, Cochrane Database of Systematic Reviews, SciELO, Web of Science, and LILACS) were systematically searched from inception through December 2024, with no language or publication date restrictions applied. Study selection followed predefined eligibility criteria, and the methodological quality of the included systematic reviews was assessed using the AMSTAR 2 tool. Conclusions: The available evidence on laser-activated irrigation in endodontics remains limited and heterogeneous. Although some systematic reviews suggest potential benefits in canal disinfection and postoperative outcomes, the findings are inconsistent and largely constrained by variability in laser wavelengths, study designs, and outcome measures. Consequently, further standardised, high-quality clinical research is required before definitive conclusions regarding the clinical effectiveness of laser-activated irrigation can be established.
- Systematic review and meta analysis of first and second generation bioceramic materials in primary dentition pulpotomiesPublication . Neves, João Albernaz; Lopes, Luísa Bandeira; Duarte, Marta Alves; Mendes, José João; Pimentel, TiagoCalcium silicate-based materials are considered the gold standard in vital pulp therapy due to their ability to induce favorable repair responses. Mineral trioxide aggregate (MTA), a first-generation bioceramic cement, has demonstrated high clinical and radiographic success rates but is associated with disadvantages such as coronal discoloration, difficult handling, and long setting time. To address these issues, second-generation bioceramic cements were developed with improved chemical composition, radiopacifiers, and handling properties. This systematic review followed the PRISMA guidelines and included a comprehensive search of PubMed, MEDLINE, CENTRAL, Web of Science, SciELO, LILACS, and TRIP databases from 2011 up to August 2023. Two independent reviewers conducted study selection, data extraction, and risk of bias assessment using the Cochrane RoB 2 tool. Meta-analysis was performed using a random-effects model to compare the clinical and radiographic success rates of first- and second-generation bioceramics in pulpotomies of primary teeth, with heterogeneity assessed using the I2 statistic. A total of 14 studies were included, involving 1128 primary molars from 637 children. The meta-analysis revealed no statistically significant differences in clinical or radiographic success rates between first- and second-generation bioceramics across follow-up periods of up to 24 months. Both first- and second-generation bioceramics demonstrate comparable clinical and radiographic success in pulpotomies of primary teeth. The choice of material should be guided by clinical considerations and practitioner preference, as no significant differences in outcomes were observed.
