Section of Dental-Oral Maxillofacial Surgery

Objectives: To evaluate the root canal morphology of maxillary premolars.

Method: This retrospective study was conducted from November 2016 to January 2017 at Aga Khan University Hospital, Karachi, and reviewed Cone Beam Computed Tomography images of maxillary first and second premolars done from November 2014 to October 2016. Frequency distribution of Vertucci's classification was determined. Chi square test was applied to determine any association between Vertucci's type and gender. SPSS 19 was used for data analysis.

Results: Of the 114 first premolars, 74(68.6%) were bi-rooted and 36(31.5%) were single-rooted. The mean lengths of buccal and palatal roots were …

The Effect Of Biologic Materials And Oral Steroids On Radiographic And Clinical Outcomes Of Horizontal Alveolar Ridge Augmentation., Amy Reichert

Theses and Dissertations

The purpose of this study was to investigate if the addition of biologic materials and/or oral steroids would affect horizontal bone gain, or the bone density of the grafted bone in horizontal alveolar ridge augmentations. A retrospective chart review was completed to assess the clinical and radiographic outcomes of 53 ridge augmentation patients. An average bone gain of 3.6mm of width was found in our study based on radiographic analysis. There were no statistically significant differences found in the linear bone gain with the addition of biologic materials and steroids. A marginally statistically significant difference was found in the bone …
