objective: this study aimed to compare the effect of using casein phosphopeptide – amorphous calcium phosphate (cpp-acp) paste, remin-pro and fluoride varnish on remineralization of enamel lesions. methods: in this experimental-in vitro study, 60 intact premolars and molars were used and flat enamel surfaces were prepared. the specimens were divided into 6 groups (n=10). after primary diagnoden...

It has been suggested that laser fluorescence close to the dental pulp shows higher values than more distant measurements. The aim of this study was to assess fluorescence on the cavity floor and to correlate these measurements with electrical resistance as a measure of residual dentine thickness. Thirty carious lesions were excavated with a bur. The endpoint of caries removal was determined by...

PURPOSE This in vitro study was performed to correlate the presence of discoloration on occlusal surfaces with its histological depth and assess its influence on Diagnodent measurements in a group of permanent and primary teeth. METHODS Ninty-five primary and 95 permanent third molars were randomly selected from a pool of macroscopically intact teeth. One site of the fissure on each occlusal ...

AIM The aims of this study were to assess the inter-examiner reliability of ICDAS and Soprolife intra-oral camera ex vivo using 5 examiners and to compare in vivo the validity of two fluorescence-based intra-oral devices in examining occlusal surfaces with early carious lesions. MATERIALS AND METHODS Thirty-seven occlusal surfaces of posterior primary and permanent teeth of 20 children were e...

OBJECTIVES To clinically evaluate the prevalence of buccal caries and white spot lesions (WSLs) at debonding in governmental and private orthodontic patients, using the International Caries Detection and Assessment System (ICDAS-II) and the DIAGNOdent Pen, and to study the correlation between the two methods. MATERIALS AND METHODS A cross-sectional study was carried out on the nonextracted pr...

STATEMENT OF THE PROBLEM The purpose of placing sealants is to inhibit caries by physical closure of the pits and fissures of teeth. A device named DIAGNOdent is useful in detecting occlusal caries by employing laser fluorescence (LF). However, there are contradictory results in the influence of sealants on LF measurements. PURPOSE The aim of this study is to investigate the effects of two di...

The aim of this work was to verify the existence of correlation between Raman spectroscopy readings of phosphate apatite (~960 cm-1), fluoridated apatite (~575 cm-1) and organic matrix (~1450 cm-1) levels and Diagnodent® readings at different stages of dental caries in extracted human teeth. The mean peak value of fluorescence in the carious area was recorded and teeth were divided in enamel ca...

AIM The aim of this study was to compare and evaluate the efficacy of different diagnostic aids for diagnosis of dental caries and to compare the validity in terms of sensitivity and specificity of all four diagnostic modalities for diagnosis of caries. MATERIALS AND METHODS Occlusal surfaces of 100 primary and permanent molars were examined using the four diagnostic systems (visual, intraora...
