Orthodontic in vivo bond strength: comparison with in vitro results.
The results appear to indicate that mean bond strengths recorded in vivo following comprehensive orthodontic treatment are significantly lower than bond strength recorded in vitro. Expand
Mandibular prognathism.
The perception of optimal profile in African Americans versus white Americans as assessed by orthodontists and the lay public.
This study was designed to assess the perceived optimal profiles of African Americans versus white Americans and found the African American sample with upper and lower lips that were more prominent compared with the white sample was significantly different. Expand
An evaluation of the use of digital study models in orthodontic diagnosis and treatment planning.
The results of the present study indicate that in the vast majority of situations digital models can be successfully used for orthodontic records. Expand
Evaluation of video imaging prediction in combined maxillary and mandibular orthognathic surgery.
Differences between the predicted and actual posttreatment soft tissue profiles may be attributed to the inaccuracy of Quick Ceph Image's default soft to hard tissue ratios when predicting the soft tissue response to combined maxillary and mandibular orthognathic surgical procedures. Expand
Orthodontic outcomes assessment using the peer assessment rating index.
Results of the study showed no statistically significant difference between the Board-accepted cases and the graduate student-treated cases for any single component of the PAR Index at either the pretreatment or posttreatment times, but analysis of treatment duration showed that a higher pretreatment PAR score and a greater percent reduction in PAR score were significantly associated with longer treatment durations.

Evaluation of the debonding characteristics of 2 ceramic brackets: an in vitro study.
The results indicate that the safest way to remove ceramic brackets with respect to reducing the chance of enamel damage is to use the debonding technique specifically designed for each. Expand
An in vitro evaluation of a metal reinforced orthodontic ceramic bracket.
Results of this study suggest that the new metal reinforced ceramic bracket (Clarity) may be recommended for clinical use because of its acceptable shear bond strength and possible reduced chances of enamel damage during bracket removal. Expand
Variability in three morphologic features of the permanent maxillary central incisor.
This investigation was undertaken to determine quantitatively the variation in three anatomic features of the maxillary central incisor, which revealed a wide range of variation in the three features measured. Expand
Orthodontic appliances and magnetic resonance imaging of the brain and temporomandibular joint.
Removal of removable components, especially archwires, with close checking of the security of banded and bonded attachments, should be sufficient in most cases requiring this diagnostic procedure. Expand
