Filter by:To describe a method of acid etching the base of a bracket, and to compare the bond failures between micro-abrasive blasted (sandblasted) brackets and acid etched brackets over an eighteen month period
The aim of this study was to evaluate and compare the effect of myofunctional trainer T4K versus twin block functional appliance on the dentoalveolar changes in children with class II division I malocclusion
The objective of this study will be to evaluate the effect of photobiomodulation on the acceleration of the orthodontic movement of molar verticalization and its effect on pain and inflammation of the periodontal tissues. Thirty-four healthy patients aged 30-60 years, who need to recover the prosthetic space for oral rehabilitation after loss of the posterior inferior dental elements and inclination of the adjacent element, will be randomly divided into 2 groups: G1 (control group) - verticalization by mini-implant + PBM (photobiomodulation) simulation (placebo); G2 (experimental group) - verticalization by mini-implant + PBM. The movements will occur with the aid of mini-implants and elastomeric chains ligatures. The PBM will occur with diode laser application, 660 nm (nanometers), 100mW (milliwatts), receiving 1J(joule) per point, 10s (seconds), 10 points (5 per buccal and 5 per lingual) and radiant exposure of 25 J / cm². The crevicular gingival fluid (FGC) will be collected to analyzed Interleukins IL1β, IL-6, IL-8, IL-10(Interleukins) and TNF-α (tumor necrosis factor) by ELISA (enzyme-linked immunosorbent assay). Radiographic shots will be taken each month to ascertain the amount (in degrees) of verticalization. To evaluate the pain, the Visual Analogue Scale will be used in all the consultations, and to evaluate the quality of life, the OHIP-14 (oral health impact profile) questionnaire will be applied. Analgesics will be given and the number of drugs will be counted. If the data are normal, they will be submitted to the Student's t-test. The data will be presented as means ± SD(standard deviation) and the value of p will be defined as <0.05.
This study is a single-blind randomized controlled trial on fixed orthodontic appliance candidates (n = 90) assigned into a control group (n = 30) and two different study groups (n = 30 in each). Patients who requiring non-extraction fixed orthodontic treatment, crowding under 5mm in the incisors and heaving at least 20 permanent teeth with healthy periodontal tissue and devoid of caries were included in the study. The control group received a standard printed educational material assisted with verbal information. The study groups either received video assisted or hands-on training about fixed orthodontic appliance and oral hygiene. The time requirements for all three educational interventions were recorded at the initial visit. The adequacy of oral hygiene is documented through plaque and gingival indices at the initial visit and 8th week of the treatment.
- Evaluate and compare initial changes in PBF between conventional and self-ligating fixed orthodontic brackets during leveling and alignment stage using 0.016" Nickle titanium (NiTi) and 0.016X0.022" NiTi archwires at different time intervals (20min, 24h, 72h, 1 week and 1 month) of initial arch wire placement.
