View clinical trials related to Root Resorption.
Filter by:Aim: The aim of the study was to evaluate and compare the extent of root resorption in the maxillary and mandibular anterior teeth during orthodontic treatment with the use of different types of brackets. Materials and methods: The study consisted of 21 patients (11 males and 10 females) within the age group of 16-25 years, having bimaxillary protrusion. They were divided into three groups. In Group 1- Conventional brackets, Group 2- Self-ligation brackets:Smart Clip (Passive), and in Group 3 Self-ligation brackets: Empower (Active) were bonded. Computed Tomography scans and Orthopantomograms were taken before start of treatment and after six months of retraction. Root resorption is computed as the difference between the pre treatment total tooth length and the post treatment total tooth length.
This study will attempt to validate a method of estimating root length on panoramic radiograph by crown measurement on intraoral digital scans.
Orthodontic treatment has been traditionally carried out with fixed appliances involving the use of stainless steel brackets and archwires. The challenge has been to move teeth and their roots effectively while minimizing iatrogenic damage such as root resorption and gingival inflammation. In recent years, with the development of new appliances and brackets such as self-ligating brackets and clear aligners there have been reports of improved periodontal status, less iatrogenic root damage and improved hygiene during treatment. Although these treatment modalities have been rapidly accepted in clinical practice, both clinical and basic science research data regarding their overall biological compatibility to support higher levels of evidence based dentistry (e.g, randomized clinical trials) is lacking. In other words, their advantages and disadvantages in this regard have not yet been scientifically evaluated. Such quantification will provide invaluable information for improvements in these treatment modalities. A randomized controlled clinical trial will be conducted with strict inclusion and exclusion criteria to test the following hypothesis (H) up to 18 months into treatment: H-1: There is no difference in the amount of root resorption caused by the three different appliances. H-2: Gingival health is not affected by the 'type of appliance' being used to correct the malocclusion. H-3: There is no difference in the amount of bacterial count and the type of appliance being used for orthodontic treatment. The hypothesis will be tested with the following specific aims (SA): SA-1: To investigate the amount of orthodontically induced inflammatory root resorption generated by treatment. SA-2: To evaluate the periodontal health of the patients with the different appliance systems. SA-3: To determine the changes in Streptococcus mutans and total bacterial counts contained in the plaque of orthodontic patients. SA-4: To ascertain whether there is an association between the microbial count and the type of appliance being used for orthodontic treatment
The purpose of the study is evaluate the histological changes of the dentinal-pulp complex and root resorption in maxillary premolars with intrusive orthodontic movement under a low power laser effects.
