SOS teeth with advanced caries and sociodemographic indicators, health-related habits and dental attendance patterns: data from the Dental, Oral, Medical Epidemiological (DOME) nationwide records-based study

BMC Oral Health. 2021 Aug 9;21(1):389. doi: 10.1186/s12903-021-01751-5.


Background: "SOS teeth" are teeth that need to be treated first, and represent dental teeth with deep caries seen clinically and radiographically which may require root canal treatment or extraction. The aims of the present research were to study the associations of SOS teeth with: socio-demographic parameters, dental attendance patterns, health-related habits among young to middle-aged adults.

Methods: This cross-sectional records-based research analyzed data from the Dental, Oral, Medical Epidemiological (DOME) repository that captures comprehensive socio-demographic, medical, and dental databases of a nationwide sample of 132,529 records of dental attendees to military dental clinics for 1 year aged 18 to 50 years.

Results: SOS teeth had a significant positive association in the multivariate analysis with male sex [OR 1.137, 95% Confidence Interval (CI): 1.079-1.199], rural versus urban Jewish locality [OR 1.748 (1.082-2.825)], and consumption of sweetened beverages [OR 1.415 (1.337-1.496)]. SOS teeth retained significant negative associations (protective parameter) with academic [OR 0.647 (0.592-0.708)] and technicians (OR 0.616 (0.556-0.682)] compared to high school education, high [OR 0.437 (0.401-0.476)], and medium (OR 0.648 (0.598-0.702)] versus low socio-economic status, urban non-Jewish versus urban Jewish locality [OR 0.746 (0.693-0.802)], Asia (OR 0.658 (0.452-0.959)], North America (OR 0.539 (0.442-0.658)] and Israel [OR 0.735 (0.686-0.788)] versus western Europe birth countries.

Conclusions: Health authorities should be familiar with this profile of the patient who is vulnerable to SOS teeth and formulate policies and allow the appropriate implementation of strategies in those in high-risk populations.
