ABSTRACT
Abstract

aim:

to assess the interdental alveolar bone density within specific regions of interest in the mandible of bruxers, mild bruxers and non-bruxers in absence or presence of influencing factors, such as orthodontia and impaction. Materials and

methods:

The study consisted of 104 subjects (64 bruxers and 40 controls) from the female students in the Faculty of Dentistry. Students were classified into bruxers, non-bruxers, and mild bruxers. The presence of modifying factors, such as impacted mandibular third molars and/or current or recent orthodontic treatment were identified. Panoramic radiographs were obtained, and the mean bone density values of interdental alveolar bone were measured using ImageJ software.

Results:

Nonbruxers had the highest mean bone density in all measured regions. The mesial aspect of the second premolar was an area of higher mean bone density in bruxers and in mild bruxers, compared to non bruxers. In the presence of orthodontic treatment, the mean bone density in non-bruxers surpassed that of bruxers and mild bruxers.

Conclusion:

Bruxism, whether mild or severe decreased the interdental mean bone density in the studied regions of interest. The presence of influencing factors affected the interdental mean bone density.
RESUMEN
Resumen evaluar la densidad ósea alveolar interdental en áreas de interés de la mandíbula de bruxómanos, bruxómanos leves y no bruxómanos en ausencia o presencia de factores como ortodoncia e impactación dentaria. Material y

métodos:

El estudio consistió de 104 (64 bruxómanos y 40 controles) estudiantes de odontología. Los estudiantes fueron clasificados en bruxómanos, bruxómanos leves y no bruxómanos. Se identificó la presencia de factores modificadores terceros molares mandibulares y/o tratamiento de ortodoncia actual o reciente. Se obtuvieron radiografías panorámicas, y los valores medios de densidad ósea del hueso alveolar interdental se midieron utilizando el software ImageJ.

Resultados:

Los no bruxómanos tuvieron la mayor densidad ósea media en todas las áreas de interés. La cara mesial del segundo premolar fue un área de mayor densidad ósea media en bruxómanos y en bruxómanos leves, en comparación con los no bruxómanos. En presencia de un tratamiento de ortodoncia, la densidad ósea media en los no bruxómanos superó a la de bruxómanos y bruxómanos leves.

Conclusión:

El bruxismo, ya sea leve o grave, disminuye la densidad ósea interdental promedio en las regiones de interés estudiadas. La presencia ortodoncia e impactación dentaria influye en la densidad ósea interdental promedio.
