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).

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).

Use of Diagnodent for diagnosis of non-cavitated occlusal dentin caries.

The purpose of this study was to evaluate the use of a laser fluorescence device for detection of occlusal caries in permanent teeth. One hundred and ninety-nine non-cavitated teeth from 26 patients aged 10 to 13 years were selected. After dental prophylaxis, two previously calibrated dentists examined the teeth.

In vitro study of laser diode 655 nm diagnosis of occlusal caries.

The aim of this in vitro study was to evaluate the performance of a new laser method (DIAGNOdent, KaVo) by comparing it to the visual inspection, conventional bitewing radiography and digital bitewing radiography. Fifty fresh permanent teeth with clinically sound or suspicious fissures were selected. The teeth were submitted to the diagnostic tests by 2 examiners independently after calibration.
