Study On Influencing Factors And Relieving Measures Of Dental Anxiety In Patients With Impacted Wisdom Tooth Extraction

Background and objectiveDental anxiety(DA)refers to the unique anxiety,tension or psychological fear of patients in the face of dental treatment,which is characterized by a significant increase in sensitivity and a significant decrease in tolerance.It’s incidence is between 10%and 65%,and it is affected by a variety of factors.Studies have shown that young women and those with poor oral health are more likely to get dental anxiety.However,there are few studies on the relationship between smoking,drinking,pain tolerance and DA.At present,the commonly used treatment methods in the world are drug therapy,aromatherapy,behavioral intervention therapy,music therapy and so on,but there are few studies on the treatment of dental anxiety in different degrees.The purpose of this study was to explore the influencing factors of dental anxiety in patients with impacted wisdom tooth extraction,and to analyze the clinical effects of decompression ball relaxation intervention and music intervention in relieving anxiety in patients with different degrees of dental anxiety.Methods1.A total of 583 patients with impacted wisdom tooth extraction were selected from the Department of Oral Surgery,the First Affiliated Hospital of Zhengzhou University from October 2018 to August 2020,including 234 males and 349 females,aged from 18 to 65 years old,with an average age of 28.04±7.90 years.All patients filled in Modified Dental Anxiety Scale(MDAS)and general condition questionnaire before operation.2.A total of 180 patients with DA were selected from the Department of Oral Surgery of the First Affiliated Hospital of Zhengzhou University from October 2018 to August 2020.90 patients with obvious anxiety and 90 patients with severe anxiety were randomly divided into decompression ball relaxation group,music group and control group.All patients filled in MDAS and pain Visual Analogue Scale(VAS)before and after intervention.3.The statistical data were analyzed by SPSS 26.0.the measurement data were expressed by x ± s,and the differences between groups were analyzed by single factor analysis of variance,independent sample t-test or non-parametric test.The counting data were expressed by percentage(%),χ2 test was used for comparison between groups,and the difference was statistically significant(P<0.05).Results1.The MDAS score was 5-24,with an average score of 13.47±4.52.There were 329 patients with dental anxiety(MDAS≥13),accounting for 56.43%,including 214 patients with obvious dental anxiety(13 ≤ MDAS≤18),accounting for 36.71%,and 115 patients with severe dental anxiety(MDAS≥ 19),accounting for 19.72%.2.DA was correlated with age,sex,self-evaluation of oral health status,previous experience of tooth extraction,pain tolerance and other factors(P<0.05),but not with education,occupation,drinking and other factors(P>0.05).Logistic regression analysis showed that gender,fear source of tooth extraction,previous experience of tooth extraction,pain tolerance and pre-extraction status were independent risk factors for DA(P<0.05).3.In patients with obvious dental anxiety,the scores of MDAS and VAS in the decompression ball relaxation group and the music group after operation were lower than those before operation(P<0.05),but there was no significant difference in the control group(P>0.05).There were no significant differences in the differences of MDAS scores before and after operation and the differences of VAS scores before and after operation between decompression ball relaxation group and music group(P>0.05).4.In patients with severe dental anxiety,the MDAS scores of decompression ball relaxation group and music group after operation were lower than those before operation(P<0.05).In the decompression ball relaxation group,the VAS scores after operation were lower than that before operation(P<0.05).There were no significant differences in the scores of VAS in the music group and in the scores of MDAS and VAS in the control group after operation than those before operation(P>0.05).There were significant differences in the differences of MDAS scores before and after operation and the differences of VAS scores before and after operation between the decompression ball relaxation group and the music group(P<0.05).5.Music intervention can relieve anxiety in patients with obvious DA and severe DA,and the effect of obvious DA is better than that of severe DA(P<0.05).Decompression ball relaxation method can improve the anxiety and pain of patients with obvious DA and severe DA,and there is no difference in effect(P>0.05).Conclusion1.56.43%of the patients with impacted wisdom tooth extraction in oral surgery clinic have dental anxiety,which should be paid more attention to.2.Women,patients who have experienced tooth extraction,poor feeling of tooth extraction in the past,poor pain tolerance and patients who are nervous or very nervous before tooth extraction are more likely to have dental anxiety.3.Preoperative decompression ball relaxation intervention and music intervention can relieve anxiety and pain in patients with dental anxiety caused by impacted wisdom tooth extraction,and decompression ball relaxation therapy may be better for patients with severe dental anxiety.
