INVESTIGATION INTO THE ACCURACY OF 850NM NEAR-INFRARED IMAGING TECHNOLOGY FOR DETECTION OF VARYING EXTENTS OF PROXIMAL ENAMEL CARIES: AN IN-VITRO STUDY
… surgery treatment planning. Skeletal cephalometry has historically been used but has been found to be unreliable and outcomes poorly correlated with facial esthetics. Despite multiple soft tissue cephalometric analyses proposed, there is no consensus on an analysis to predictably …

Variation in cranial base flexion and craniofacial morphology in modern humans
Cranial base flexion has been used extensively as a baseline or standard from which to interpret differences in craniofacial growth and morphology. Lateral cephalometric radiographs of 414 adults representing seven samples from around the world were compared for variation in cranial base and facial …

A Study of Craniofacial Asymmetry in Monozygotic and Dizygotic Twins Using Posteroanterior Radiographs
This project investigated craniofacial asymmetry in a prospective study among monozygotic (identical) versus dizygotic (fraternal) twins and sibling pairs. Posteroanterior radiographs that had previously been collected were used in this study and the zygosity of the twins had previously been …

TEMPOROMANDIBULAR JOINT DISORDERS AND NASAL SEPTUM DEVIATION IN DENTOFACIAL DEFORMITY PATIENTS
Introduction: The purpose of this study was to subclassify the types of facial asymmetries present in a pre-surgical dentofacial deformity patient population to determine the prevalence of each subcategory. Associations between the craniofacial characteristics of each asymmetry and pre-surgical Jaw …

Evaluation of the Treatment Effects of the Functional Regulator of Fränkel in the Correction of Angle Class II Malocclusions
One of the greatest challenges an orthodontist faces is the correction of Angle Class II malocclusions. Several different treatment options are available to correct saggital jaw discrepancies that often exist in these individuals. Traditionally, headgear has been used to restrain forward maxillary …

A Retrospective Cephalometric Growth Study of Sagittal Airway in Skeletal Class II Patients
<p>Purpose: The study retrospectively determined the average sagittal pharyngeal airway widths in Class II males and females between 7 to 16 years of age and changes in sagittal airway with increasing age. Additionally, this study determined whether average airway differs between gender at each age …

Comparison of Maxillary Anterior Teeth Width to Facial Dimensions among Three Races
<p>Dental esthetics and tooth proportions have become increasingly relevant in dentistry, as the cosmetic demands of patients increase. Determining the appropriate esthetic dimensions of the maxillary anterior teeth is an important aspect in fixed and removable prosthodontics. The proportion of …
