Esthetic improvements of postorthodontic white-spot lesions treated with resin infiltration and microabrasion: .

Angle Orthod 2019 Feb 5. Epub 2019 Feb 5.

Objective:: To compare the esthetic improvement between postorthodontic white-spot lesions (WSLs) treated by resin infiltration and microabrasion for 12 months.

Materials And Methods:: A total of 20 patients with 128 teeth with postorthodontic WSLs were recruited. A simple randomized, split-mouth, positive controlled design was used to allocate patients to resin infiltration or microabrasion groups. Read More

An orthodontic-orthognathic patient with obstructive sleep apnea treated with Le Fort I osteotomy advancement and alar cinch suture combined with a muco-musculo-periosteal V-Y closure to minimize nose deformity.

Angle Orthod 2019 Jan 30. Epub 2019 Jan 30.

In some severe skeletal Class III patients, mandibular setback surgery using sagittal split ramus osteotomy (SSRO) is performed to correct mandibular protrusion. However, in patients diagnosed with obstructive sleep apnea syndrome (OSAS), the risk of OSAS worsening as a result of the SSRO is very high. Maxillary advancement could reduce the degree of mandibular retropositioning and expand the skeletal framework in the pharyngeal region, leading to enlargement of the airway. Read More

Upper Airway Features of Unilateral Cleft Lip and Palate Patients in Different Growth Stages.

Angle Orthod 2019 Jan 29. Epub 2019 Jan 29.

Objectives:: To compare growth-related changes of skeletal and upper airway features of unilateral cleft lip and palate subjects (UCLP) with non-cleft control (NCC) subjects by using lateral cephalograms.

Materials And Methods:: The sample comprised 238 subjects, collected cross-sectionally, divided into 2 groups: 94 with UCLP, and 144 NCC, subdivided into 4 groups according to their growth stages by using cervical vertebral maturation stage (CVMS). The subgroups were defined as early childhood (stage 1), prepubertal (stage 2: CVMS I and II), pubertal (stage 3: CVMS III and IV), and postpubertal (stage 4: CVMS V and VI). Read More

An in vitro comparison of ultraviolet versus white light in the detection of adhesive remnants during orthodontic debonding.

Angle Orthod 2019 Jan 17. Epub 2019 Jan 17.

Objectives:: To assess the effectiveness and efficiency of ultraviolet (UV) illumination compared to conventional white light in the detection of fluorescent-tagged adhesive remnants during orthodontic debonding.

Materials And Methods:: Orthodontic brackets were bonded to extracted human premolars using one of two bonding resins having fluorescent properties (Pad Lock, Reliance Orthodontics, Itasca, Ill; Opal Bond MV, Opal Orthodontics, South Jordan, Utah; n = 40 each). The brackets were then debonded and, in each adhesive group, half the teeth had the remaining adhesive resin removed under illumination using the operatory light and the other half using a UV (395 nm) light emitting diode (LED) flashlight (n = 20/group).

Is there an asymmetry of the condylar and coronoid processes of the mandible in individuals with unilateral crossbite?

Angle Orthod 2018 Dec 28. Epub 2018 Dec 28.

Objectives:: To evaluate if there is a true skeletal asymmetry of the condylar and coronoid processes of the mandible in growing individuals with unilateral posterior crossbite (UPC) either functional or not.

Materials And Methods:: This cross-sectional study screened a total of 1120 cone beam computed tomography (CBCT) scans based on inclusion and exclusion criteria. The final sample comprised 20 CBCT images of individuals with UPC and 19 CBCT images of individuals without transverse malocclusion. Read More
