Prevalence of Occlusal Interferences Among the Saudi Sub-population: A Cross-Sectional Study

Aim: To study how occlusal interferences are distributed among Saudi sub-populations.

Materials and methods: A total of 96 participants were recruited in this study between the ages of 15–50 years. The static occlusion was assessed by intraoral examination. The dynamic occlusion was determined with the aid of a shimstock. The working and nonworking sides' occlusal contacts for the lateral excursion were noted. A handheld mirror and shimstock were provided for the participants to use while performing the exercises.

Results: It was found that occlusal interference affects most populations (89.5%). Protrusive interference was the most typical type of interference (34.7%). The non-working side interference was reported at 29.5%, while working interference was in 25.2%. The youngest patients (15–25 years) were the most affected by occlusal interference, while the oldest patients were the least affected.

Conclusion: The majority of populations have occlusal interference, and protrusive interference is the most prevalent. Also, it was concluded that younger patients are more vulnerable to occlusal interferences.
