Objectives: This study was aimed at comparing the mechanical parameters of ceramics made using the addition and subtraction technique.

Methods: A search was performed on four search engines on 5th April 2023. Quality assessment was performed using study type-specific scales.

Topography of the mandibular canal in male human skulls originating from different time periods.

Background: Dynamic advances in dentistry, especially in implantology has inspired researchers to carry out many studies investigating the topography of the mandibular canal and its ethnic differences. The aim of the study was a comparative analysis of variations in the position and topography of the mandibular canal based on radiographic images of human mandibles originating from modern and medieval skulls.

Materials And Methods: Morphometric examination of 126 radiographs of skulls (92 modern and 34 medieval skulls) was included.
