Master Title

Treatment of post-orthodontic white spot lesions by resin infiltration compared to acid microabrasion

Master Abstract

The aim of this study was to evaluate and compare the effectiveness of resin infiltration and acid-microabrasion in treatment of post-orthodontic white spot lesions. This was a split-mouth, randomized controlled clinical trial. Ninety post-orthodontic white spot lesions (scores 1 and 2 on the ICDAS II scale) in 36 quadrant were divided into two groups. Ninety post-orthodontic white spot lesions (scores 1 and 2 on the ICDAS II scale) in 36 quadrant were divided into two groups. Group I lesions (44 lesions) were treated by ICON-Infiltrant with assessment of the lesions before , after application , after 3 months and after 6 months Group II lesions (46 lesions) were treated with acid-microabrasion with assessment of the lesions before, after application, after 3 months and after 6 months Visual assessment of white spot lesions was done using International Caries Detection and Assessment System (ICDAS-II) for scoring dental caries.The scoring criteria according to the ICDAS-II system for Coronal Smooth Surface Caries are graded from 0 to 6 Patient satisfaction score was recorded according to patient's own selection for each quadrant before, after intervention, after 3 months and after 6 months follow up . The results revealed before application, there was no statistically significant difference between the two groups. While at after application, Icon showed statistically significantly lower mean score than Opalustre. After 3 months as well as after 6 months, there was no statistically significant difference between the two groups. While patient satisfaction scores revealed that before application as well after application, there was no statistically significant difference between the two groups. While After 3 months, Icon showed statistically significantly higher mean score than Opalustre. After 6 months, there was no statistically significant difference between the two groups.

PHD Title

Comparison of Accuracy Between Two Methods of Digital Three Dimensional Indirect Orthodontic Brackets Bonding Techniques: A randomized controlled trial

PHD Abstract

Indirect bonding is a technique in which orthodontic attachments are transferred from dental casts (working models) and bonded onto dentition using a transfer tray. Indirect bonding is a preferred technique for many orthodontists as it is less time consuming compared to direct bonding. Evolution in technology allowed forming transfer trays digitally by the integration of computer-aided design and computer-aided manufacturing (CAD/CAM). This study was conducted to evaluate and compare the accuracy of orthodontic brackets placement using 3D printed transfer tray and transfer tray made over 3D printed models with resin brackets by measuring the differences between the virtual bracket positions and actual bracket positions after indirect bonding. All upper and lower incisors, canines and premolars in 14 patients (280 teeth) were divided into two groups for indirect bonding: Group A: 140 brackets in 7 patients were bonded by 3D printed indirect bonding transfer tray. Group B: 140 brackets in 7 patients were bonded by vacuum-formed transfer tray on 3D printed models with resin brackets. Intra oral scanner was used initially to obtain stereolithographic file for virtual brackets positioning and another scan was taken after brackets bonding. Superimposition of virtual STL files and post bonding STL files was done by Geomagic Control X 20software to measure linear and angular deviation of brackets positions. When comparing the discrepancy between upper arches brackets positions in both groups there was no statistically significant difference between two arches in all dimensions except occluso- gingival linear dimensions where group (A) showed the higher mean values. Regarding the discrepancy between lower arches brackets positions in both groups there was no statistically significant difference between both arches in all dimensions except occluso- gingival linear dimensions and bucco-lingual linear where group (A) showed the higher mean values. Both groups showed inaccurate transfer brackets regarding torque measurements. Both groups showed directional bias of transferred brackets toward mesial, gingival and buccal direction. Both groups showed no significant difference in rate of debonding of brackets.
