Evaluation Of The Bone Thickness Of Mandibular Molars Using Cone Beam Computed Tomography, Deniz Yanık, Ahmet Mert Nalbantoglu

Journal of Dentistry Indonesia

Objective: To investigate buccal and lingual bone thicknesses and fenestration rate of mandibular first and second molars using cone-beam computed tomography (CBCT).

Methods: A total of CBCT images of 41 patients were selected and overall 120 mandibular molars were investigated. The buccal and lingual alveolar bone widths were measured at apex of the roots. The prevalence of fenestration in mandibular molars was recorded. Statistical analyses were performed.

Results: The buccal bone widths of mesial root of second molars were significantly lower than the lingual (p<0.05). The lingual bone widths of mesial and distal root of second molars were lower than the buccal (p<0.05). The lowest thickness of buccal and lingual bone was observed in mesial root of first molar and distal root of second molar. The prevalence of fenestration in mandibular first and second molars was 5% and 10%.

Conclusion: The buccal bone widths were lower at the first molar than the second molar. …

Relationship Of Natural Occlusal Plane With Different Anatomical Landmarks, Mehwish Khan, Syed Murtaza Raza Kazmi, Farhan Raza Khan, Sameer Quraeshi

Section of Dental-Oral Maxillofacial Surgery

Objective: To evaluate the parallelism of natural maxillary occlusal plane with inter-pupillary line and ala-tragus line, and to evaluate the anatomic relationship of natural mandibular occlusal plane with retromolar pad among dentate subjects.
Methods: The cross-sectional study was conducted from September 2017 to February 2018 at Fatima Jinnah Dental College, Karachi, and comprised front and profile photographs of subjects aged 20-28 years while holding the camper's plane against the maxillary occlusal plane. The photographs were imported in a software and an interpupillary line was drawn and the angle with Camper's plane was measured. On both profile pictures, lines were drawn …
