This study analyzed comparatively, by confocal laser scanning microscopy (CLSM), the depth of caries-like lesions produced by biological and chemical artificial models in permanent and primary dentin. Six primary molars and six premolars were used. The occlusal enamel was removed and a nail polish layer was applied on the specimens, except for a 4 x 2 mm area on dentin surface. Half of specimen...

AIM The aim of the study was to assess the efficacy of chemo-mechanical method for caries removal based on histological analysis and scanning electron microscopy of dentine samples. METHODS Forty-five freshly extracted human deciduous and permanent teeth with dentinal caries were used in this in vitro study. The teeth were allocated to two different technique groups. Chemo- mechanical caries ...

A shift in caries prevalence from occlusal surfaces to approximal surfaces has been demonstrated by epidemiological studies. Two recent meta-analyses evaluated the performance of visual examination and radiography for carious lesion detection, and reported low sensitivity but high specificity for early approximal caries detection. This suggests that the conventional methods have a higher risk o...

Background and Aim: The aim of this study was to conduct in vitro and in vivo studies for the evaluation of antimicrobial potential of four Nigerian indigenous chewing sticks and to compare the oral effects of the popular Nigerian chewing sticks with toothpastes and other teeth-cleansing agents on a total of 21 and 17 oral bacterial strains isolated from children and adult dental caries respect...

OBJECTIVE To evaluate the performance of an impedance spectroscopy technology for detecting non-cavitated occlusal caries lesions in permanent teeth in vitro. The method was compared with a commonly used laser fluorescence device and validated against histology. MATERIAL AND METHODOLOGY A non-cavitated sample of 100 extracted posterior teeth was randomly selected and assessed for caries on en...

Dental caries is a biofilm-dependent disease, and Streptococcus mutans the primary etiological agent involved in initiation of disease. The extensive use limited range antimicrobial drugs dentistry has led to development drug-resistant bacteria. There an increasing need find new alternatives against Globally, there continuous effort towards identifying natural anti-caries agents for prevention ...

OBJECTIVE The purpose of this study was to evaluate the efficacy of the laser fluorescence (LF) device in detecting in vitro demineralization and remineralization of smooth surface caries-like lesions. BACKGROUND DATA The early detection of smooth surface caries-like lesions is important to provide proper management of carious lesions, and allows monitoring of them over time. Also, some autho...
