Association of gender specific distribution of sclerotic dentin and the direction of the vertical root fracture – an in vitro study.

Aim: The primary aim of this study is to determine if there is a relationship between the direction of vertical root fracture and the gender-specific distribution of sclerotic dentin.Methods and Material: For further morphometric analysis to ascertain sex and age, thirty premolars with an oval shaped morphology and a single root were selected. After that, they were decoronated, placed in acrylic blocks, and tested vertically using a universal testing machine untill the fracture occured. To evaluate the correlation between the direction of sclerotic dentin and the direction of the fracture line, teeth were sectioned and observed under a stereomicroscope Statistical analysis used: For the purpose of examining the correlation (P
