The treatment group was comprised 21 crossbite (mean age = 13.3 ± 2.1 years). Members this treated ARME appliance. control 17 Angle Class I who kept under observation 12.3 0.8 Lateral frontal cephalograms taken before expansion (T1), immediately after (T2), at postexpansion...

To evaluate transverse dimensional changes in dentoalveolar and skeletal structures caused by hybrid expander, using cone-beam computed tomography (CBCT).The CBCT records of nine patients (five boys four girls) (mean age 13.61 ± 0.72 years) treated with expander were examined. images taken at pretreatment after the expansion. ELSA (point equidistant to both foramina spinosa) was determined as a reference point compare distances all three dimensions. Nineteen transversal dimensions angles...

The aim of this study was to evaluate the effects different surface preparation methods on shear bond strength (SBS) orthodontic metal brackets aged nano-hybrid resin composite surfaces in vitro. A total 100 restorative discs, 6 mm diameter and 3 thick, were obtained treated with an ageing procedure. After ageing, samples randomly divided as follows according methods: (1)Control, (2)37% phosphoric acid gel, (3)Sandblasting, (4)Diamond bur, (5)Air-flow 20 central incisor teeth used for...

ABSTRACT Objective: To quantitatively evaluate the effects of asymmetric rapid maxillary expansion (ARME) on cortical bone thickness and buccal alveolar height (BABH), to determine formation dehiscence fenestration in surrounding posterior teeth, using cone-beam computed tomography (CBCT). Materials Methods: The CBCT records 23 patients with true unilateral skeletal crossbite (10 boys, 14.06 ± 1.08 years old, 13 girls, 13.64 1.32 old) who had undergone ARME were selected from our clinic...

The purpose of this report is to present Apert syndrome patient by highlighting craniofacial characteristics and orthodontic approach treatment.The patient, a 16-day-old female the second child healthy parents, was admitted our department with primary complaint cleft palate. She had cone-shaped calvarium, midface hypoplasia, syndactyly hands feet, hypertelorism, proptosis After taking maxillary impression, an acrylic appliance applied orientate growing enable feeding.A case undergoes...

To evaluate and compare the effects of enamel demineralization, microabrasion therapy casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) application on shear bond strength (SBS) orthodontic brackets bonded to surfaces color.Eighty freshly extracted human maxillary premolar teeth were allocated one four groups. Brackets directly non-demineralized in Group I (control group), demineralized II, after CPP-ACP III IV. The samples stored water for 24 h at 37°C then underwent thermocycling....

Gagging can become a conditioned response that makes dental treatment difficult or impossible for both the individual and dentist. The aim of this study is to report 50 year old female two children (15 11 years old) with exaggerated gag reflex referred Faculty Dentistry Selçuk University.During obtaining records, taking impression procedure was elicited patients' hypersensitive gagging reflex. Therefore, it decided administer intranasal midazolam facilitate accurate impressions. After given...

ABSTRACT Objectives: In response to patient demands for better aesthetics in orthodontics, manufacturers have developed different aesthetic wires and brackets. The aim of this study were evaluate the mechanical properties archwires. Thus, color surface roughness archwires analyzed. Materials Method: Seven brands evaluated measurements. measurement each sample was performed using a spectrophotometer. A profilometer used measure roughness. For roughness, Ra (average roughness), Rq (root mean...
