Immediate effects of the Hook on Pain and Mouth Opening after Fitting Dental Appliances

INTERVENTION: This is a two‐arm, double‐blind, randomized controlled clinical study. The sample will consist of volunteers who have had fixed orthodontic braces fitted, who will be randomly allocated via the website (www.randomizer.org) into an experimental group and a control group, and who will receive treatment by percutaneous diaphrolysis and sham (simulated percutaneous diaphrolysis), respectively, with a single session. Experimental group: 16 subjects will receive one session of the real percutaneous diaphysis technique on the apical portion of the tooth roots and periodontal ligament, on the skin around the mouth, using a stainless steel metal hook. Control group: 16 individuals will receive one session of the simulated percutaneous diaphrolysis technique (Sham). In both groups, the session will take place in the first 24 hours after the orthodontic appliance is fitted. The volunteers will be assessed using the Visual Analog Scale (VAS), which will evaluate subjective pain, the pressure algometer, which will evaluate the pressure pain threshold, and the pachymeter, which will evaluate the range of motion during mouth opening. The assessments will be carried out before and after the treatment session. CONDITION: Atypical Facial Pain C23.888.592.612.330 PRIMARY OUTCOME: It is hoped to find an improvement in the range of movement when opening the mouth and in the perceived and measured intensity of pain with the use of diacutaneous fibrolysis in volunteers with orofacial pain following the placement of fixed orthodontic appliances who have undergone this technique. SECONDARY OUTCOME: No secondary outcomes expected INCLUSION CRITERIA: Volunteers starting orthodontic treatment aged between 12 and 45 years; accepting and signing the conditions of the study in accordance with the Informed Consent Form and Assent Form; good general health; absence of caries lesions or periodontal diseases
