In a series of 200 consecutively debanded patients receiving comprehensive orthodontic treatment with the edgewise appliance, six (3%) showed severe resorption (greater than one-quarter of the root length) of both maxillary central incisors. For other teeth, resorption of this extent occurred in less than 1% of the patients. Using a case-control design, the(More)
Thirty-one adults who had been treated with orthodontics alone for Class II malocclusions were recalled at least 5 years posttreatment to evaluate cephalometric and occlusal stability and also their satisfaction with treatment outcomes. The data were compared with similar data for long-term outcomes in patients with more severe Class II problems who had(More)
PURPOSE To compare recovery for clinical and health-related quality of life (HRQOL) outcomes after third molar surgery in patients predicted to be at risk for delayed recovery, treated with or without intravenous (IV) corticosteroids at surgery. PATIENTS AND METHODS Patients at least 18 years of age and with all 4 third molars below the occlusal plane(More)
Ectodermal dysplasias (ED) are a heterogeneous group of inheritable disorders characterized by abnormal development of embryologic ectoderm derivatives. The purposes of this study were to: 1) create baseline cephalometric norms for male children with ED; 2) assess craniofacial growth and development in hypohidrotic ED male children with severe hypodontia,(More)
OBJECTIVE This study sought to assess child-caregiver concordance regarding children's oral health related quality of life (OHRQoL) using the Child Oral Health Impact Profile (COHIP). METHODS The sample comprised treatment-seeking children aged 8-15 with pediatric (n = 141), orthodontic (n = 135), and craniofacial (n = 100) needs and their caregivers.(More)
The purpose of this study was to compare intracanal bacterial reduction on teeth instrumented with 0.04 tapered nickel-titanium (NiTi) rotary instrumentation to bacterial reduction when using a stainless-steel K-file step-back technique using sterile saline irrigation. Forty-eight patients with apical periodontitis were randomly assigned treatment type. The(More)
OBJECTIVE To evaluate reliability in 3-dimensional (3D) landmark identification using cone-beam computerized tomography (CBCT). STUDY DESIGN Twelve presurgery CBCTs were randomly selected from 159 orthognathic surgery patients. Three observers independently repeated 3 times the identification of 30 landmarks in the sagittal, coronal, and axial slices. A(More)
OBJECTIVE In patients with cleft lip and palate, the aim of the study was (1) to determine and compare the level of agreement among examiners' subjective evaluations of static and dynamic lip form; (2) assess possible bias of examiners' subjective evaluations; and (3) determine the impact of lip scarring on an examiner's subjective assessment of dynamic lip(More)
The amelogenesis imperfectas (AI) are a diverse group of genetic disorders primarily affecting the quality and or quantity of enamel, however, affected individuals often have an open bite malocclusion. Three main AI types are recognized based on the perceived developmental mechanisms involved and the enamel phenotype. The purpose of this investigation was(More)
PURPOSE This report compares the skeletal stability and treatment outcomes of 2 similar cohorts undergoing bilateral sagittal osteotomies of the mandible for advancement. The study groups included patients stabilized with 2-mm self-reinforced polylactate (PLLDL 70/30), biodegradable screws (group B), and 2-mm titanium screws placed in a positional fashion(More)
