A dissertation submitted in partial fulfilment of the requirements for the degree of Master of Dentistry of the University of the Witwatersrand, Johannesburg. / This dissertation studies the development of the anterior successional teeth prior to eruption, their eruption paths and position of emergence of these teeth in Cercopithecus aethiops, the vervet monkey. The eruption of the permanent dentition is divided into four stages, equivalent to four chapters, with a fifth chapter devoted to an analysis of the pattern or sequence of eruption. This pattern is compared to those of other workers and possible reasons for tooth sequence polymorphism are discussed. Twenty three skulls, fourteen female and nine male are examined and a representative sample chosen from each phase of dental development for dissection. Photographs of each stage are presented, accompanied by a descriptive text but no measurements are recorded. This is a visual and descriptive presentation which 'opens the window' to those aspects of the Cercopithecoid dentition which are not as readily observable by other methods such as clinical examination or radiography. / WHSLYP2017

Objectives: This retrospective study aims to compare the effect of different mandibular setback amount by vertical subsigmoid osteotomy (VSSO) on the pattern of condylar remodelling in both metric and morphologic analysis at 1 year post surgery. Materials and Methods: 200 patients diagnosed of mandibular prognathism and had undergone VSSO with various setback amounts from 2007 until 2012 at the Prince Philip Dental Hospital were included in this study. Presurgical and 1 year post surgical Postero-Anterior Cephalogram, Lateral Cephalograms and Cone Beam Computed Tomography (CBCT) Scans were retrieved. Tracings of plain cephalometric radiographs were performed. CBCT data sets were used to create 3D condyles to measure the linear and condylar axis angle value in multiplanar view. Finally the pre and postsurgical 3D condyle-ramus units were superimposed using stable registration point in the condylar neck and ramal area above the lingual to assess the condylar bone remodelling by topographic and multiplanar slide views. Result: From the plain radiographic tracings, there were no significant differences in the changes of ramus inclination angle, intergonial width and total ramus angle between postoperative (T2) and preoperative (T1) values across the setback groups. A gradual increase in the postoperative sagittal condylar axis angle is detected with greater setback in the CBCT multiplanar analysis while other linear and angular condylar changes were not significantly different. 3D Topography (T2 -T1) superimposition analysis of the condylar surface showed no significant relation between the remodelling changes and the setback magnitude except at the superior posterior zone. Multiplanar view (T2-T1) superimposition analysis in the coronal and sagittal planes showed no significant relationship between the remodelling changes and the setback magnitude. However there was higher proportion of positive remodelling following higher setback amount at the midanterior and posteromedial zone in the axial plane. Conclusion: Condyle remodelling is noted to be positive and not detrimental following VSSO. The positive remodelling effect remains stable regardless of the amount of VSSO setback. / published_or_final_version / Dental Surgery / Master / Master of Dental Surgery

The aim was to compare the movements of the mandible during chewing different food types. We hypothesized that the mandibular movements would vary significantly between the food types. For each participant, we built and affixed the dental appliances and attached infra red emitting diodes to record the mandibular movements using a 3D motion capture device (Optotrak). Participants chewed on four test foods that varied in texture: Italian bread stick, dried beef stick, carrot and cheese. Results indicated greater amplitude of the lateral displacement of the mandibular movements when chewing cheese. The velocity of the lateral displacement was greater for soft foods such as cheese. The velocity of the horizontal displacement increased during beef chewing. Furthermore, we found shorter movement cycle duration while chewing carrot. We concluded that the movements of the mandible vary significantly during chewing different food types.
