Prevalence and Patterns of Oral Behaviors in Romanian Adults: An Exploratory Study

Background and Objectives: Harmful repetitive oral behaviors impose an excessive load on the stomatognathic system. Being unconscious and involuntary, patients are often unaware of their occurrence and, consequently, of their potential consequences. We aimed to screen the Romanian population for harmful oral habits, while simultaneously emphasizing the importance of employing validated and internationally accepted diagnostic instruments for a better approach to these conditions. Materials and Methods: An observational, descriptive study was conducted on 459 adults, recruited through a multiregional convenience sampling from the general population in Romania. Oral behaviors were assessed using the validated Oral Behaviors Checklist (OBC-21) questionnaire. Data was analyzed using descriptive and comparative statistics, with significance set at p < 0.05. Results: The sample included 363 women (79.1%) and 96 men (20.9%), with a mean age of 33.3 years. The mean total OBC score was 22.45 ± 10.27, indicating a moderate prevalence of oral behaviors. 60.1% of participants were classified as low-risk and 39.9% as high-risk, with none in the no-risk category. The most frequently reported behaviors were sleeping positions exerting pressure on the mandible (57.7% “very often”), sustained talking (11.3%), and nocturnal bruxism (10.5%). Younger adults (20–49 years) presented significantly higher OBC scores compared to both younger extremes (18 years) and older adults (>60 years) (p < 0.001). No significant gender differences were observed in total OBC scores; however, unilateral chewing, sustained talking, and holding objects between the teeth were significantly more frequent among women (p < 0.05). Conclusions: This is the first study to investigate oral behaviors in a Romanian adult population. Postural and involuntary activities were the most prevalent and age influenced OBC scores, while gender differences were limited to individual behaviors. Conducting screening and implementing therapeutic interventions based on the assessed level of risk could enhance the overall management of the condition.
