Introduction: Endodontic treatment of teeth with open apex requires a non-conventional approach and the goals new therapies are to allow root's complete development differently from what happens with traditional apexification technique. Objective: This study aimed to review the literature on the most recent regenerative endodontic procedures. Literature review: Regenerative endodontics goal is to obtain pulp vitality. Some case reports on donor-obtained dental stem cells show promising results. Other types of laboratory-based dental stem cell therapies are under development. Conclusion: Dentin-pulp complex shows regenerative capacity, but the literature lacks evidence to validate the regenerative therapies in endodontic practice.

RESUMOO objetivo do presente estudo foi avaliar, por meio de questionário Oral Health Impact Profile em versão abreviada (OHIP-14), o impacto das reabilitações com implantes dentários em região anterior, em adultos atendidos em um curso de especialização em Implantodontia. Participaram 35 pacientes, de ambos os gêneros, atendidos no segundo semestre de 2017 e contatados entre julho e setembro de 2019. Por telefone, os pacientes foram agendados para uma entrevista presencial, realizada por três pesquisadores treinados que aplicaram o OHIP-14. Os dados foram analisados descritivamente e para o cálculo do OHIP-14 foi considerado o método da adição; para variáveis qualitativas foi aplicado teste de Qui-quadrado e quantitativas foi feito teste de correlação de Spearman. Adotou-se nível de significância de 5%. Um total de 58 procedimentos implanto/protéticos foi realizado. Predominaram as mulheres (57,1%) e a reabilitação de incisivos laterais superiores (34,5%). O valor do coeficiente Alfa de Cronbach foi alto (0,854), indicando consistência interna do instrumento. Não foram observadas diferenças estatisticamente significativas para associação entre gênero e idade, dimensões e OHIP-14 total (p > 0,05). A média geral e o desvio-padrão do OHIP-14 total foi 8,46 (± 8,76). Pela estratificação por gênero, apenas a dificuldade de alimentação apresentou diferença (p = 0,048), com homens relatando piores impactos. A reabilitação implanto/protética em indivíduos com perda dentária em região estética tem impacto na qualidade de vida relacionada à saúde bucal e deve ser melhor pesquisada, com vistas a melhor compreender os efeitos psicológicos do tratamento nos pacientes.Palavras-chave: qualidade de vida, implantes dentários, estética.

Gingival recession is an oral health problem that affects a large part of the population. Several treatments are suggested in the current literature; among them is the use of buccal fat pad grafting. The objective of this case report is to describe the treatment of a Miller Class I gingival recession using a nonpedicled buccal fat pad graft immediately after performing the surgery for buccal fat pad removal (bichectomy technique). First, bilateral surgical removal of the buccal fat pad was performed with the main objective of eliminating oral mucosa biting. The recipient site was prepared to receive a portion of the fat pad that was cut and macerated in a size that was sufficient to cover the recession. The patient was followed up at 15, 30, 60, and 365 days postsurgery, and the results showed an elimination of the oral mucosa biting and complete coverage of the gingival recession. It was concluded that the nonpedicled buccal fat pad graft is another option for the treatment of Miller Class I recessions.

Aim: The aim was to evaluate the bond strength at the cement/dentin interface in the post space, after specimens were treated with different final irrigation protocols, followed by cementation with a dual resin cement. Methods: Forty-eight extracted uniradicular human premolars were divided into four groups according to the irrigation (n = 12): control with distilled water; 2.5% sodium hypochlorite (NaOCl) + ethylenediaminetetraacetic acid (EDTA); 2.5% NaOCl + passive ultrasonic irrigation (PUI); and 2% chlorhexidine (CHX). The pull-out test was performed. The results were evaluated using ANOVA with Tukey’s paired comparisons, with a significance of 5%. Results: When all groups were compared, significant difference occurred (p = 0.006), and in the paired comparison, NaOCl + PUI and CHX differed (p = 0.005). The CHX showed significantly higher adhesive defects between cement and dentin than other groups. Conclusions: The final irrigation protocol for cleaning after preparation for post space directly influences the bond strength at the cement/dentin interface.
