About the trial
What the trial wants to find out
This Clinical and radiographic study will be designed to evaluate the temporomandibular joint condition post longstanding mouth opening during dental procedure using rubber dam. primary outcome : preoperative and postoperative assessment of interincisal distance , occlusal biting force , visual analogue scale , lateral excursion movement and Magnetic resonance imaging (MRI).

Secondary outcome: investigator will try to answer the question of what is the best duration of time could the dentist use rubber dam isolation in dental procedures without harmful effect on TMJ and its supporting structures?
The 3 groups in the trial
- Group 1 - Short Duration Rubber Dam ApplicationTreatment being tested
Patients undergoing dental procedures with rubber dam isolation for 30 to 60 minutes. This group will help assess the impact of short-term mouth opening on temporomandibular joint (TMJ) condition.
Treatment: Application of a rubber dam during dental treatments for varying durations.
- Group 2 - Medium Duration Rubber Dam ApplicationTreatment being tested
Patients undergoing dental procedures with rubber dam isolation for 60 to 90 minutes. This group will help evaluate the effects of medium-term mouth opening on TMJ condition.
Treatment: Application of a rubber dam during dental treatments for varying durations.
- Group 3 - Long Duration Rubber Dam ApplicationTreatment being tested
Patients undergoing dental procedures with rubber dam isolation for more than 90 minutes. This group will provide insights into the impact of long-term mouth opening on TMJ condition.
Treatment: Application of a rubber dam during dental treatments for varying durations.
