Push-out bond strength of calcium hydroxide and mineral trioxide aggregate based sealers

The adhesiveness of six root canal sealers: Acroseal, Endo CPM, Epiphany, White MTA, Sealapex and Sealer 26 to dentin, was evaluated in a push-out test design. Methods: Twenty eight roots of freshly extracted teeth were gauged with a size 5 Largo drill. With a cutting machine slices of 2 mm were prepared, rinsed with 5.25% NaOCl and a final rinse with 17% EDTA, dried and filled with one of the sealers. After setting their bond strength was measured in a mechanical testing machine. The data were statistically analyzed by using a One Way ANOVA and post hoc Tukey test. Results: The mean and standard deviation from values of bond strength was: Sealapex 2.2±0.4; Endo CPM 3.8±1.3; White MTA 6.0±1.4; Epiphany 10.9±2.6; Sealer 26 12.3±2.3; and Acroseal 12.2±1.4. Acroseal, Sealer 26 and Epiphany presented a significantly (P<0.01) greater bond strength compared with the other sealers. Also White MTA showed higher adhesiveness compared with Endo CPM and Sealapex (P<0.01). Conclusion: The bond strength between endodontic sealers and root dentin was maximal when Acroseal, Sealer 26 and Epiphany were used; Sealapex e Endo CPM, in turn, presented the lowest bond strength mean values.

Sistemas de retenção intrarradicular: considerações teóricas e comportamento biomecânico

The aim of this study was to review the current scientific literature to discuss the biomechanical behavior and characteristics inherent to both cast post and core and the prefabricated posts used in the practice of restoring endodontically treated teeth. To identify studies of this review, it was performed a detailed and advanced search strategy to the databases PubMed and Medline. It was used as descriptors: endodontically treated teeth, post, core, fiber post and metal post. Inclusion criteria were: clinical trials, randomized controlled trials, in vitro studies, literature reviews and systematic reviews with or without meta-analysis of the last 10 years that addressed the theme. Exclusion criteria were: articles without abstracts, animal studies, articles whose language was not English and articles from journals that do not belong to the Dentistry field. Of a total of 35 articles, after an analysis according to inclusion and exclusion criteria, 23 articles were selected. Most of the current scientific literature indicates that the prefabricated fiber reinforced and ceramic posts should be appointed for endodontically treated teeth that have a minimum height of 2mm ferrule. As for the cast metal cores, along with pre-fabricated metal represent a good prosthetic option, when weakened teeth have to be restored for any reason. Despite the large number of studies, there is still a lack of longterm prospective studies that evaluate the effectiveness of these posts in the treatment of endodontically treated teeth.

Organização da demanda de um Centro de Especialidades Odontológicas

Introduction: Secondary care in oral health in Brazil is still a little researched topic. Objective: The aim of this study was to analyze the resolution of dental services in SUS based on the referral to secondary attention and backreferral to primary attention. Methodology: It’s a descriptive, quantitative study that used secondary data collected from dental records of patients seen at Centre of Dental Specialties (Ceo) in a city of São Paulo State. Result: It was analyzed 1030 dental records. Just 1236 proceedings received referral to Ceo and among then, 86.4% showed the first attendance on Basic Health Unity (UBS) through spontaneous demand and 50.4% (n=623) received referral to endodontic treatment. There was evasion of 2.27% of studied population (n=28) on the first specialized consultation. Among 1208 proceedings that started the treatment in Ceo, 62.6% (n=757) were finalized and received back-referral to primary attention, that finalized 61.1% (n=463) of proceedings. To conclude the treatment, considering the time spent in Ceo and primary attention, there was variation according to specialty: periodontics – 62 days (sd ±68) and endodontics – 71 days (sd ±51.8), requiring 3 consultations in average, regardless specialty. Conclusion: The Centre of Dental Specialties gave referral and attention to the majority of demand, regardless specialty. However, there are many cases of evasion during dental treatment, alerting managers to develop methods to entice these patients, reducing service expenses and raising solvability of dental procedures previously initiated.
