Abstract

The aim of this study was to compare the operating microscope and optical fluorescence device as diagnosis methods of caries lesions in cleft and lip palate patients through ICDAS-II system. Three-hundred and fifty-two labial, palatal, mesial and distal surfaces of the teeth closest to the cleft area of children aging 6-12 years-old (mean of 10 years and 8 months-old) at mixed dentition, with complete unilateral cleft lip and palate (right or left), complete bilateral cleft lip and palate, unilateral cleft lip and alveolus (right or left) and bilateral cleft lip and alveolus were assessed. The teeth closest to cleft area were observed according to the following groups: visual-tactile examination (Group 1), visual-tactile examination with the aid of operating microscope (Group 2), visual examination with the aid of fluorescence device (Group 3).Prior to the assessments, dental surfaces were cleaned by dental floss and dental prophylaxis with pumice and tergentol with the aid of a rubber cup and a WHO dental probe. Firstly, under light and after 5-second air-drying, the surfaces were evaluated by unaided visual-tactile clinical examination (Group 1). Immediately after, the same surfaces were examined by visual-tactile clinical examination with the aid of operating microscope (Group 2) and optical fluorescence device (Group 3). In all assessments, ICDAS-II scores were used by two examiners previously calibrated and trained and inter-examiner agreement was obtained by Kappa test in 103 surfaces. The comparison among diagnosis methods and of the percentage of each ICDAS-II score among the methods was respectively performed by using Friedman and Chi-square tests with level of significance of 5%. No statistically significances were detected among the types (P=0.214) and effectiveness (P=0.725) of the different diagnosis methods for the different ICDAS-II scores. The operating microscope and optical fluorescence examinations were not more effective than unaided visual-tactile clinical examination of teeth closest to cleft area. Further studies comprising greater prevalence of caries lesions are necessary to verify the effectiveness of these new technologies. (AU)
