Objective: This paper aims to describe bruxism as the contributing
the factor of RAS that needed an interdisciplinary treatment approach to
achieve successful treatment.
Methods: A 46-year-old male came to the Dental Hospital, Faculty of
Dentistry, Universitas Hasanuddin with the complaints of mouth ulcers for
2 weeks since it was bitten while he was sleeping. These complaints often
recur in the same area since about 10 years ago. He had seen the dentist
several times, but there was no improvement. Clinical examination
revealed two yellowish irregular ulcers accompanied with tooth indentation
on the right lateral of the tongue and lower labial mucosa. We detected
bruxism from the patient history, clinical examination, and questionnaire evaluation. We assumed that bruxism was the main contributing factor in
this case. The management of oral ulcers included tooth grinding and
prescribing Doxycycline oral rinses 100 mg three times a day. The patient
was also referred to prosthodontists and psychologists for management of
bruxism. Results: The patient felt complete improvement since routinely using a mouthguard and coping with his anxiety.
Conclusion: Bruxism can play a role as a contributing factor in RAS.
Recognizing and managing parafunctional habits is very important to
achieve successful treatment in this case.
