Comparison Of External Root Resorption In Orthodontic Treatment Between Self-Ligating And Conventional Bracket Systems, Nuriah Bohari, Noor Airin Koah, Rohana Ahmad

Journal of Dentistry Indonesia

The relationship between orthodontic bracket systems and external root resorption has remained debatable. Objective: This study compared the magnitude and pattern of the external root resorption of maxillary incisors as induced by self-ligating and conventional bracket systems via cone beam computed tomography and medical imaging programs. Methods: Eight participants were recruited for each bracket system. Their maxillary incisors were scanned at the beginning (T0) and 18 months into treatment (T1). Three-dimensional models of the four maxillary incisors at T0 and T1 were reconstructed using the Mimics program. The difference in root length between T0 and T1 models represented external root …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction.

The purpose of this study was to compare perceptions of efficacy and efficiency of Self-Ligating Brackets vs. conventional brackets between practicing Orthodontists and Orthodontic Residents.

Methods.

Cross-sectional survey research using a three-wave emailing of addresses from the current American Association of Orthodontists directory. The directors of all orthodontic residency programs in the US were asked to also distribute to all residents. The survey included five sections: (1) respondents' experience, (2) factors that influence, (3) positive or negative factors, (4) the perceived efficiency/efficacy, and (5) demographics. A 39% response rate (N=707) was obtained.

Results.

Over half (51.8%) …
