Depression Levels in Relation to Oral Hygiene, Gingival Health Status, and Salivary Constituents in a Group of Dental Students: A Cross-Sectional Study.

Aim: In this study, the effects of depression on oral hygiene, gingival health conditions, and some salivary components (total protein, magnesium, and calcium) were explored.

Materials And Methods: A total of 207 dental students aged 20-21 years (third grade) in a College of Dentistry, University of Baghdad, Baghdad, Iraq, were examined.

The Impact of Dental Environment Stress on Dentition Status, Salivary Nitric Oxide and Flow Rate.

Aim: This study aimed to assess the dental caries experience among dental students with different levels of dental environment stress in relation to salivary nitric oxide (NO) and flow rate of whole unstimulated saliva.

Materials And Methods: The study involved 300 dental students. They were classified into three categories (mild stress, moderate stress, and severe stress) according to dental environment stress questionnaire (DESQ); clinical examination for dental caries was carried out.
