Assessment of the Dental Photography Imaging as Diagnostic Tool for Incipient Pits and Fissures Caries Lesions in Permanent Teeth
Objectives: The aim of this study is to assess the digital dental photography imaging as a diagnostic tool for detecting occlusal pits and fissures caries lesions in permanent teeth and compare it to the direct visual examination., To validate the actual scoring of pit and fissure caries lesions t on extract premolars teeth
Methods: . Direct clinical examinations , Tooth surfaces were examined After carefully cleaning and drying. magnification dental loupe (X3.5 magnification) rusing ICDAS II to categorize the lesions, hypoplasia, erosion or tooth wear, fissure sealants, and restorations were excluded. PHOTOGRAPHIC IMAGES, All the images were photograph with a professional DSLR camera (EOS Canon 800D, f/2.8L Macro 100-mm lens) and Macro ring Flash YN14EX (YONGNUO) after tooth cleaning and drying. Photographs were taken in 1:2 magnification using f/23 aperture and 1/200 shutter speed based on the best results obtained from pilot testing.. All assigned teeth were evaluated clinically by the two AEGD residents and the two restorative consultants then re-examine the photographs blindly in a presentation room using a large screen.. HISTOLOGICAL EXAMINATION
The diagnostic validation of actual scores was performed by Downer histological examination. Sections were scored according to Downer histological examination as score 0 no enamel demineralization, score 1 enamel demineralization limited to the outer 50% of the enamel layer
Results: the data were analyzed using 2 way annova test for diffeent variables, the calibration between examiners have shown adequate agreenet for the incepient caries, all studied photographs have shown high sensitivity with great accuracy for detection the pits and fissures non cavitated lesions. the histological scaning for sectioned teeth have validated the accuracy of the images.
Conclusions: with in limitation of this clinical observation, the Cross-over analysis of clinical examination, Digital photography and Histological sectioned scanning. All have shown that professional digital dental photography could be used as an adequate and precise tool for detecting pits and fissure incipient caries
