Filter by:Three-dimensional Assessment of Root Resorption following treatment with clear aligners using Cone Beam Computed Tomography Design: A randomized, controlled, crossover, double-blind clinical study including twenty six adult , aged 18-25 years old.
the aim of this study is to evaluate the effectiveness of injection I-PRF to accelerate alignment and leveling of the upper anterior teeth and reduce the time required for treatment.
More accurate management of resorption can be achieved thanks to the three-dimensions volumetric and linear analysis, and the axial classification presented in this study.
The majority of previous studies for early detection of Orthodontically Induced Inflammatory Root Resorption (OIIRR) were conducted to assess individual biomarkers which are representative of single biological pathway. To our Knowledge, no studies have been employed Gingival crevicular fluid (GCF) proteomic analysis to identify potential biomarkers for OIIRR. Therefore; the aim of this study is to use the advantage of testing a package of biomarkers via doing proteomic analysis of GCF which could help in making a more precise personalize diagnosis and treatments, thereby providing orthodontists additional information that cannot be deduced from clinical parameters.
Objectives: The aim of this study is to investigate the effect of photobiomodulation therapies on root resorption compared with the placebo group. Materials and Methods: 30 patients, who were admitted to the …………. University Faculty of Dentistry Orthodontics Department for treatment, with an indication of upper right 1st premolar tooth extraction was included. Before the individuals' orthodontic treatment, 0.022 slot MBT brackets and tubes were placed on the maxillary 1st premolar and molar. A 150g buccal tipping force was applied to the 1st premolar. Individuals were then randomly divided into 3 groups. For the first group; laser application was performed with a 810 nm GaAlAs laser device at 0,3,7,14,21 and 28 days to 8 J/cm2. Second group; an LED application according to the manufacturer's instructions with a 850 nm wavelength and 20 mW/cm2 output power for 10 minutes per day during the experiment. Third group; a placebo therapy was completed whereby a laser device that did not make active pulses was used. At the end of four weeks, the amount of root surface resorption was compared using micro-CT imaging after the extraction of the teeth.
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
