Comparison of temporary anchorage devices and transpalatal arch-mediated anchorage reinforcement during canine retraction.

Objective: The purpose of this study was to compare the dental and skeletal effects of canine retraction using conventional anchorage reinforcement systems and comparing them with the usage of TADs.

Materials And Methods: The sample consisted of 50 patients having Class I malocclusions with bimaxillary protrusion indicated for first premolar extraction, and allocated into two groups. The first group consisted of 25 patients with a mean age of 18,7 years (min:14, max:22 years, 16 girls and 9 boys) that TADs were applied as an anchorage mechanic between attached gingiva of upper second premolar and first molar teeth.

Three-dimensional analyses of palatal morphology and its relation to upper airway area in obstructive sleep apnea.

Objective: To evaluate the relationship between palatal morphology and pharyngeal airway morphology in patients who have obstructive sleep apnea (OSA) and compare with a nonsnoring and nonapneic control group.

Materials And Methods: Three-dimensional maxillary dental cast measurements from 25 OSA patients (6 women, 19 men) with a mean age of 41.5 (4.

Shear bond strength of brackets to demineralize enamel after different pretreatment methods.

Objective: To compare the influence of demineralized and variously pretreated demineralized enamel on the shear bond strength of orthodontic brackets.

Materials And Methods: Sixty bovine enamel specimens were allocated to five groups (n  =  12). Specimens of group 1 were not demineralized and were not pretreated, but served as controls.

Utilization of a modified bite guard for preventing traumatic macroglossia.

This clinical report describes the treatment of a patient having traumatic macroglossia due to schwannoma in the craniocervical region. Enlarged tongue or macroglossia may compromise vital functions of the patient. To avoid a chronic tongue bite trauma, a bite guard that was inspired from a habit breaker was fabricated.

Mandibular hypoplasia with curvilinear distraction.

Mandibular distraction with intraoral curvilinear distractor is an effective procedure for lengthening the mandibular corpus and ramus dimensions. Mandibular distractor is valuable for the treatment of hypoplastic mandible. The aim of this article was to describe the treatment of a patient with hypoplastic and severely retrognathic mandible resulting from isolated Pierre Robin sequence, by means of curvilinear distraction osteogenesis followed by fixed orthodontic treatment.

Effects of nasoalveolar molding therapy on nasal and alveolar morphology in unilateral cleft lip and palate.

Objective: The objective of this study was to evaluate the effects of presurgical nasoalveolar molding (PNAM) therapy on nasal and alveolar tissues in patients with unilateral cleft lip and palate.

Patients And Methods: Twenty-two patients with a mean age of 23 days, having complete unilateral cleft lip and palate, were included in this prospective study. After the impressions were taken of the palatal and nasolabial regions separately, the maxillary and nasal plaster models were scanned for linear, angular, and area measurements before and after PNAM therapy.

Effects of titanium plate fixation on mandibular growth in a rabbit model.

Purpose: The purpose of this study was to evaluate the effect of metallic rigid fixation of mandibular corpus fracture on mandibular growth in growing rabbits.

Materials And Methods: Thirteen 90-day-old white New Zealand rabbits weighing 2 to 2.6 kg were included in this study.

Kenny-Caffey Syndrome: oral findings and 4-year follow-up of overlay denture therapy.

Kenny-Caffey Syndrome (KCS) is an extremely rare osteosclerotic bone dysplasia associated with hypocalcemia and ocular abnormalities. Although the condition is well reported in the medical literature, dental manifestations have not been discussed in great detail. The purpose of this report is to present specific oral features and prosthetic management in a KCS patient.

Effect of acidulated phosphate fluoride and casein phosphopeptide-amorphous calcium phosphate application on shear bond strength of orthodontic brackets.

Objective: To evaluate the effect of a recently introduced prophylactic agent, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), on shear bond strength of brackets and compare it with the effect of acidulated phosphate fluoride (APF).

Materials And Methods: Forty-eight freshly extracted mandibular bovine incisors were used. Teeth were randomly divided into four groups (n = 12) as follows: group 1 served as control, and no pretreatment was performed on the enamel; group 2, enamel was treated with 1.

Evaluation of the treatment changes of functional posterior crossbite in the mixed dentition.

Introduction: Functional posterior crossbite (FPXB) malocclusion is frequently seen in the deciduous or mixed dentition. It is often accompanied by lateral mandibular shift and mandibular midline deviation because of the reduction in the width of the maxillary dental arch. The aims of this prospective study were to examine in detail the morphologic, skeletal, dental, and functional effects of FPXB, and the effects of maxillary expansion treatment with quad-helix appliance.

Repositioning of premaxilla in bilateral cleft lip and palate using a "J-hook headgear".

The purpose of this clinical approach is to present the successful treatment of the severely protruded and extruded premaxilla with high-pull J-hook headgear. Two patients with bilateral cleft lip and palate deformity and a protruding and extruding premaxilla causing a deep bite were treated with high-pull J-hook headgear and fixed orthodontic appliances. The lateral cephalometric measurements before and after orthodontic treatment were evaluated with Ricketts analysis.

Effect of self-etching primer and adhesive formulations on the shear bond strength of orthodontic brackets.

Purpose: Despite many published articles on the bond strength of self-etching primers and adhesives in the restorative dentistry literature, there have been relatively few laboratory studies of the bond strength of new orthodontic materials, and, in most of these published studies, investigators used various methodologic approaches during different stages of the in vitro testing procedures. The aim of this study was to compare the shear bond strength of 4 self-etching primer and adhesive formulations, a nonrinse conditioner and acetone adhesive system, and a conventional system.

Material: The self-etching products tested were Prompt L-Pop (3M ESPE, Seefeld, Germany), Clearfil SE Bond (Kuraray Dental, Osaka, Japan), FL Bond (Shofu Dental, Kyoto, Japan), and One-Up Bond F (Tokuyama, Tokyo, Japan); the nonrinse conditioner and acetone-based adhesive system was NRC and Prime&Bond NT (Dentsply International, Konstanz, Germany); the conventional acid-etch and bond system was Transbond XT (3M Unitek, Monrovia, Calif).

Condylar disc relationships and vibration energy in asymptomatic class I 9- to 12-year olds.

A proper diagnosis is the key to successful treatment. The purpose of this study was to evaluate the temporomandibular joints (TMJ) by means of lateral and anteroposterior cephalograms, transcranial temporomandibular radiographs, magnetic resonance imaging (MRI), and TMJ electrovibratography (EVG) in asymptomatic and orthodontically untreated Angle Class I subjects. The study sample comprised 31 (13 boys, 18 girls) asymptomatic Class I children with a mean age of 9.
