The objective of this study was to analyze the provision of non-surgical endodontic retreatments in Brazil's public dental services from 2008 to 2022. A time series was outlined for this purpose. The annual numbers of non-surgical endodontic retreatments were retrieved from the Brazilian National Outpatient Information System and adjusted per 100,000 inhabitants to obtain the incidence between 2008 and 2022.

- This study examined how radiotherapy (RT) and chemoradiotherapy (CRT) affect the wear and surface roughness of human enamel and dentin after a simulated abrasive challenge.
- Specimens from healthy patients and head and neck cancer patients who underwent RT or CRT were tested, with no significant differences in enamel wear between the groups, but RT showed lower wear profiles compared to CRT and control groups.
- In dentin, there were no differences in wear profiles, but both RT and CRT resulted in increased surface roughness compared to the control, highlighting the impact of radiation treatment on dental tissues.
Brazil's public healthcare system (SUS) offers specialized oral health services to Brazilians, but the productivity of specialists, such as Pediatric Dentists, has not been characterized. Therefore, the objective of this study was to characterize the outpatient dental procedures (ODPs) carried out by Pediatric Dentists within the SUS. An epidemiological study with an ecological, longitudinal, retrospective, and quantitative approach was conducted.

This study evaluated territorial disparities in dental care for disabled persons in Brazil's public healthcare system from 2014 to 2023. The person-year incidence of outpatient dental procedures carried out by special care dentistry specialists and hospitalizations for dental procedures for disabled persons were compared across different regions and against the national estimate. In addition, productivity was correlated with oral health-related indicators.
