Restorations performance after selective caries removal to soft dentine: 18-month follow-up of a controlled clinical trial.

Objective: This randomized controlled clinical trial aimed to evaluate the clinical performance of composite resin restorations placed after selective caries removal to soft dentin (SCRSD) or stepwise excavation (SW) over an 18-month period.

Methods: Inclusion criteria were patients with permanent molars and/or premolars presenting deep caries lesions (≥50 % of the dentin thickness). Teeth were submitted to SCRSD (n = 76) or SW (n = 76).

Cost-effectiveness of selective caries removal versus stepwise excavation for deep caries lesions.

A multicenter, randomized controlled clinical trial evaluated the effectiveness of two treatments for deep caries lesions in permanent molars - selective caries removal (SCR) to soft dentin with restoration in a single visit, and stepwise excavation (SW) - regarding pulp vitality for a 5-year follow-up period. The present study aimed to determine the cost-effectiveness of these treatments. Treatments were conducted in two Brazilian cities (Brasília and Porto Alegre).

Chapter 9.3: Current Concepts of Caries Removal in Daily Practice.

Although the discussion about the amount of carious dentin to be removed during cavity preparation is quite old, concepts for caries removal have evolved and changed considerably over the last decades. The antiquate understanding that it was necessary to eliminate the microbial contamination of a cavity before placing the restoration was replaced by the current knowledge that maintaining contaminated dentin beneath restorations is inevitable and is not associated with treatment failure. This chapter brings together the body of evidence behind carious dentin removal to indicate a conservative treatment, aiming to preserve both tooth vitality and structure.

Incidence and progression of gingival recession over 4 years: A population-based longitudinal study.

Aim: To describe changes in gingival recession (GR) at buccal and palatal sites in adults over an average follow-up of 4 years.

Materials And Methods: Baseline data were obtained from a multistage probabilistic representative sample of 1023 individuals aged ≥35 years from Porto Alegre, Brazil. Buccal and palatal/lingual GR were analysed.

Restorations after selective caries removal: 5-Year randomized trial.

Objective: To compare the survival of restorations placed in deep caries lesions after selective caries removal to soft dentin (SCRSD) over a 5-year period. A secondary aim was to investigate whether the material (amalgam or resin composite) affected the survival of restorations.

Methods: This study used data derived from a multicenter randomized controlled clinical trial (Clinical trials registration NCT00887952).

Enamel Subsurface Caries-Like Lesions Induced in Human Teeth By Different Solutions: A TMR Analysis.

This study assessed the effectiveness of models for developing subsurface caries lesions in vitro and verified mineral changes by transverse microradiography (TMR). Enamel blocks from permanent (n=5) and deciduous teeth (n=5) were submitted to lesion induction by immersion in demineralizing solutions during 96 h, followed by pH cycles of demineralization (de) and remineralization (re) for 10 days. Two de-/re solutions were tested.

Occurrence and predictors of gingivitis and supragingival calculus in a population of Brazilian adults.

The aim of this study was to determine the occurrence of gingivitis and calculus and their predictors in a population of adults in Brazil. A representative sample of 758 adults from 35 to 59 years of age from Porto Alegre city was examined. A structured questionnaire was applied.

Gingival recession and oral health-related quality of life: a population-based cross-sectional study in Brazil.

Objectives: To assess the association between gingival recession (GR) and oral health-related quality of life (OHRQoL) in a Brazilian population of adults.

Methods: A representative sample from Porto Alegre city was drawn in 2011 using a multistage probability sampling strategy. For this study, 740 individuals, 35-59 years of age and with ≥6 teeth, were included.

Dental caries in individuals with Down syndrome: a systematic review.

Background: Many studies have shown a lower experience of caries in people with Down syndrome compared to individuals without Down syndrome, but this issue has not been critically evaluated.

Aim: To conduct a systematic review of the international literature on dental caries experience in people with Down syndrome.

Methods: 27 subjects (32 permanent posterior teeth) with deep caries lesions composed the sample. In this single-arm long-term prospective study, the inclusion criteria were risk of pulp exposure during caries excavation, positive response to the cold test, absence of spontaneous pain or sensitivity during percussion, and radiographic absence of a periapical lesion.

Health promotion and dental caries.

The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies and actions such as food and health policies, and general hygiene (including oral hygiene), among others.
