A mobile-phone-based diagnostic tool, which most of the population can easily access, could be a game changer in increasing number examinations people with dental caries. This study aimed to apply deep learning algorithm diagnosing stages smooth surface caries via smartphone images. Materials and methods: training dataset consisting 1902 photos teeth taken an iPhone 7 from 695 was used. Four mo...

BACKGROUND AND AIM: According to the effect of the adhesive and substrate type on the bond strength, examination of the adhesive is required in all aspects. The aim of this study was to evaluate the shear bond strength of different adhesive systems to normal dentin (ND) and caries affected dentin (CAD) in permanent teeth. METHODS: Thirty extracted molars with small occlusal caries were selected...

Secondary caries has been reported as the main reason for restoration replacement. The aim of this in vitro study was to evaluate the performance of different methods--visual inspection, laser fluorescence (DIAGNOdent), radiography and tactile examination--for secondary caries detection in primary molars restored with amalgam. Fifty-four primary molars were photographed and 73 suspect sites adj...

The detection of dental decay has conventionally been dependent upon direct visual assessment of the dried tooth surface under good illumination, tactile assessment of open dental caries using a probe to help clean debris within fissures, clinical experience and the use of dental radiography. Studies have shown considerable variation berween clinicians in the detection of dental caries. Recent ...

Aim: To evaluate the comparative efficacy of Polymer bur (Smartprep) and Conventional burs (Carbide bur & Diamond Points) in selective Dentin caries removal. Materials and method: 15 freshly extracted carious human premolars and molars were selected for this study. These teeth were split in the center of carious lesion, in order to obtain two corresponding half. Thus 30 samples were prepared in...

The early caries lesion in bovine tooth enamel was studied by two different X-ray diffraction systems at the SPring-8 third generation synchrotron radiation facility. Both allowed us simultaneous measurement of the small and large angle regions. The beam size was 6μm at BL40XU and 50μm at BL45XU. The small-angle scattering from voids in the hydroxyapatite crystallites and the wide-angle diffrac...
