Non-carious cervical lesions (NCCLs) have a non-bacterial origin and produce a loss of tooth structure at the cemento-enamel junction. A review of the literature reveals that these lesions may have a multifactorial etiology (chemical, abrasion, abfraction). The role of heavy biting forces in the pathogenesis of NCCLs is yet to be firmly established. Treatment and preventive measures for NCCLs can be improved if the etiology can be clearly identified and treated.Objective: This prospective clinical trial measured the volume loss (increase in size) of NCCLs and the occlusal biting forces applied to these teeth; diet and tooth brushing analysis, followed by …
3-Dimensional Comparison Of Hard And Soft Tissue Asymmetry In, Philip H. Pan
3-Dimensional Comparison Of Hard And Soft Tissue Asymmetry In, Philip H. Pan
All ETDs from UAB
Class III malocclusions are particularly prevalent in the Asian population. Threedimensional imaging has improved the ability to portray the three-dimensional characteristics of soft tissue face and underlying skeletal hard tissue. While soft tissue reflects the underlying hard tissue structures, soft tissue may either provide a compensation for hard tissue asymmetry or potentially exacerbate the asymmetry. The current study is novel in that the hard tissue and soft tissue asymmetries are both analyzed relative to the same reference point, and using 3D imaging, we have attempted to elucidate a compensation tendency between the hard and soft tissues. The sample was comprised …
Investigation Of Lateral Incisor Crown Root Angulation And Impacted Maxillary Canines, Samuel Philip Purnell
Investigation Of Lateral Incisor Crown Root Angulation And Impacted Maxillary Canines, Samuel Philip Purnell
All ETDs from UAB
Objective: The primary aim of this study was to determine if there is a difference in the mesiodistal crown-root angulation of maxillary lateral incisors between patients with impacted maxillary canines and a control population. Secondary aim 1 compared the same angle measured on panoramic radiographs to determine if a difference existed between the CBCT measurement and the panoramic radiograph measurement. Secondary aim 2 looked to determine if there was a correlation between maxillary lateral incisor tooth width and the mesiodistal crown-root angulation. Materials and Methods: CBCT's were reformatted so that the mesiodistal crown-root angulation of maxillary lateral incisors could be …
