Effect of resveratrol on bone formation in the expanded inter-premaxillary suture: early bone changes

TANCAN UYSAL

Objective –The aim of this study was to evaluate the effects of local resveratrol (RSVL) administration on bone formation in response to expansion of the interpremaxillary suture, in rats. Material and Methods – Twenty 50- to 60-day-old male Wistar rats were separated into two equal groups. Both groups were subjected to expansion, and 30 cN of force was applied to the maxillary incisors with helical-spring. Twenty-four hours after appliance placement, single-dose 10 lmol ⁄ kg RSVL in the dimethylsulfoxide (DMSO) was injected to the inter-premaxillary suture in the experimental group. In ...Daha fazlası

OPG and RANKL levels around miniscrew implants during orthodontic tooth movement

İLKNUR VELİ | ŞÜKRÜ ENHOŞ

Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken from the mesiobuccal aspects of the loaded and unl ...Daha fazlası

Relationship between odontogenic bacteremia and orthodontic stripping

TANCAN UYSAL

Introduction: The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic stripping procedure. Methods: The study included 29 orthodontic patients (mean age, 18.2 6 3.4 years). We used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used at a low speed (\15,000 rpm; 10 seconds) on the mandibular anterior teeth. Blood samples were collected by inserting a cannula into the left antecubital fossa. A baseline sample was taken before treatment, and a second sample was taken after the stripping procedure. T ...Daha fazlası

Rapid maxillary expansion effects on dynamic measurement of natural head position

TANCAN UYSAL

Objective: To identify the effect of rapid maxillary expansion (RME) procedure on dynamic measurement of natural head position (NHP). Materials and Methods: The treatment group comprised 23 patients, 12 girls and 11 boys (mean age: 10.1 6 1.1 years), and the control group comprised 15 subjects, 8 girls and 7 boys (mean age: 9.7 6 1.4 years). The test subjects underwent RME treatment using full cap acrylic device, and the mean amount of expansion was 5.48 mm. An inclinometer and a portable data logger were used to collect the NHP data. Intragroup changes were evaluated by using nonparamet ...Daha fazlası
