Effects Of Music Therapy On Dental Anxiety During Impacted Wisdom Teeth Extraction

Objective:Using epidemiological study to research the morbidity and prevalence of dental anxiety in oral and maxillofacial surgery outpatients, to investigate the factors related to dental anxiety in teeth extraction patients and to observe the clinical application value of music therapy in impacted teeth extraction in patients with high dental anxietyMethods:Using Corah’s modified dental anxiety scale (MDAS) and questionnaire of dental anxiety general factor,the morbidity and prevalence in a total of 800 outpatients over 12-years-old with dental anxiety were evaluated. Single factor and multiple-factor analysis were involved in the assessment of dental anxiety and affecting factors in selected subjects.1. A total of 25 high dental anxiety patients needing bilateral symmetrical mandibular third molar extraction diagnosed in our department from 2016 to 2017 were randomly assigned to music therapy groups and a control group after the first or second extraction. Music therapy with high-speed turbine assistance was provided for impacted teeth extraction in experimental group under local anesthesia, and high-speed turbine extraction under conventional local anesthesia was conducted in control group. Blood pressure and heart rate in two groups were recorded 30 minutes and 5 minutes before operation, anesthetic injection,-beginning of extraction, duration of extraction, end of extraction and 30 minutes after operation. Postoperative satisfaction, MDAS before and after operation were implemented.Results:1. A total of 768 qualified questionnaires were acquired,with effective rate of 96.13%, in patients aged between 12～91 with an average age of 30.76±15.59; MDAS scores ranged from 4-20, with an average score of 10.21±3.29, and an incident rate of 21.4% when MDAS≥13 (high dental anxiety). Statistical significances were observed between groups in gender, age group, duration of extraction, relative accompany,previous extraction experience, relative extraction experience, pain tolerance, mental status, health status, psychological status before extraction, self-assessment of oral hygiene, and dental anxiety morbidity (p<0.05); no statistical significance was observed in education degree, extraction type, ethnicity, life history, preference of music, personality, occupation, first extraction or not(p>0.05). Higher risks in dental anxiety were caused by gender, relative accompany, psychological status before extraction and self-assessment of oral experience were displayed by Logistic regression analysis.2. In the control group, statistical significance was observed in systolic pressure between 30 minutes after operation, beginning of extraction, and duration of extraction (p<0.05); no statistical difference was found in diastolic pressure regarding different periods (p>0.05); statistical significance was observed in heart rate between 30 minutes after operation, beginning of extraction, and duration of extraction(p<0.05); statistical difference was observed in heart rate between beginning and end of extraction (p<0.05); statistical significance was observed in heart rate between beginning of extraction and 5 minutes before operation (p<0.05); no statistical significance was found in systolic pressure, diastolic pressure and heart rate between 5 minutes before operation and 30 minutes before operation (p>0.05).In the experimental group, statistical significances was observed in systolic pressure between 30 minutes after operation and 30 minutes before operation,anesthetic injection, beginning of extraction, and duration of extraction (p<0.05);statistical significance was found in diastolic pressure between 5 minutes before operation and 30 minutes before operation, anesthetic injection, extraction beginning,duration of extraction and end of extraction (p<0.05); significant difference was observed in diastolic pressure between beginning of extraction and 5 minutes before operation (p<0.05); significant differences was observed in heart rate between 30 minutes after operation and 30 minutes before operation, anesthetic injection,beginning of extraction, and duration of extraction (p<0.05); statistical significance was observed in heart rate between extraction ending and anesthetic injection,beginning of extraction, and duration of extraction (p<0.05); statistical significances was calculated in heart rate between 5 minutes before operation, and 30 minutes before operation, anesthetic injection, beginning of extraction, and duration of extraction (p<0.05).No statistical significance was observed in systolic pressure, diastolic pressure and heart rate between experimental group and control group during different periods(p>0.05). Higher satisfaction was found in experimental group than control group with statistical significance (p<0.05).Conclusion:1. Higher morbidity of dental anxiety were observed in out-patient teeth extraction patients, which needs more attention. The factors involved in its occurrence were gender, age, duration of extraction, relative accompany, previous extraction experience, relative extraction experience, pain tolerance, mental status, health status,psychological status and oral hygiene.2. Music therapy alleviated anxiety in patients before operation and stabilized systolic pressure and heart rate. However, the anxiety in mandibular molar extraction patients can not effectively reduced by music therapy with high-speed turbine assistance, nor did the blood pressure and heart rate.3. Music therapy with high-speed turbine can assistance remarkably elevated the satisfaction in patients.
