Abstract

Abstract: Objective: To investigate the impact of nonsurgical periodontal treatment in patients with social anxiety disorder (SAD) and controls without phobia. Study design: randomized controlled trial. Setting: Institute of Psychiatry from FMUSP (Ipq-FMUSP). Subjects: patients seeking for Social Phobia treatment at Ipq-FMUSP. Controls: Hospital staff at the HC-FMUSP or volunteers from a list of other studies conducted at the Ipq-FMUSP. Methods: Dental evaluation: probing depth, clinical attachment level and bleeding on probing will be recorded at 6 sites per tooth, as well as the plaque and/or calculus indexes. The number of decayed, missing and filled teeth (DMFT index) will be also assessed. The visual analogue scale (VAS) will be applied for the assessment of pain after probing after the probing recording. Patients will receive a clinical evaluation for halitosis using a Halimeter® to verify the concentration of the volatile sulfur compounds. Main psychiatric assessment: Structured Clinical Interview (SCID) for DSM-IV-TR adapted for DSM-5, the Liebowitz Social Anxiety (LSAs). Duration and frequency: after the initial clinical assessment (dental and psychiatric) patients will be randomized into three groups. The Groups 1 and 2 (G1 and G2) will receive periodontal and psychiatric treatment after the initial evaluation. The Group 3 (G3) will receive the psychiatric treatment after initial evaluation, but the periodontal treatment after the improvement of psychiatric condition (3 months after the initial assessment). The non-surgical periodontal treatment will be performed preferably within 24 h. Patients will be reevaluated 3 and 6 months after the end of nonsurgical periodontal treatment. (AU)
