A COMPARISON OF 2 DIFFERENT RAPID PALATAL EXPANSION TECHNIQUES FROM THE POINT OF ROOT RESORPTION

The aim of this investigation is to compare Haas and Cast Cap Splint d evices from the point of root resorption. The material comprised thirt y-eight upper and twelve lower premolar teeth derived from nineteen pa tients who required RME and subsequent removal of the first premolars as part of their full banded orthodontic treatment. Root resorption an d repair areas were observed on the buccal surfaces of premolars. Repa ir tissue was cellular cementum in both groups. There was no significa nt difference between these two techniques from the point of root reso rption amount.
