Tooth Wear And Its Complications Epidemiological Investigation And Preventive Treatment

Objective:Survey tooth abrasion and its complication dentine hypersensitivity disease in taiyuan province which involving employees between 22-60 years old, evaluation the tooth legal effectiveness for the treatment of dentine hypersensitivity of teeth by clinical trials, The purpose is to provide a scientific basis for prevention,mitigation and treatment of tooth abrasion for this group of people and their complications of dentine hypersensitivity.Methods:Adopting multi-stage random cluster sampling method,extraction,The public security bureau of yingze district, The spirit,The customs,Daqin four logistics unit worker in taiyuan,Totally 556 people participate in the questionnaire and oral cavity, and received543 valid questionnaires. Collect molar area dentine hypersensitivity of the medical records In the oral cavity hospital, diagnosis of 57 of dentine hypersensitivity molar in the24 patients as the research object, according to their varying degrees of dentine hypersensitivity, divided into three groups: primary, secondary and tertiary groups,use self contrast method before and after the treatment, observed the tooth sensitive employment in each group after one month, Compare the clinical effect of before and after treatment.Results:Epidemiological survey, tooth abrasion prevalence was 84.5% in taiyuan city worker,Tooth wear and age were statistically exist linear correlation(χ2=50.185, P <0.001),and with the increase of age the tooth abrasion level rising; Using ROC curveanalysis of the critical value of tooth abrasion, concluded that tooth abrasion boundary between the age of 33.5 years,age is greater than 33.5 years old crowd tooth abrasion will have significantly higher risk. Tooth wear of molar area wear at much higher incidence of premolar group and front teeth. The prevalence of dentine hypersensitivity is 37.6%;Through analysis of variance and multiple comparisons between groups conclude that dentine hypersensitivity starts at an average age of 45.05 years, 100% of patients with shock symptoms of dentine hypersensitivity with enamel dentin dysplasia, Dentine hypersensitivity of teeth distribution and tooth abrasion of a distribution are basically identical.Clinical trials, adjustable teeth legal treatment of dentine hypersensitivity total effective rate was 68.42%,the treatment of dentine hypersensitivity to level 1 group effective rate was 90.9%, to level 2 group effective rate was 65.2%, to level 3 group effective rate was 33.3%, efficient Highest level 1group, efficient lowest level 3 group.Conclusion:The age is the main influence factors of tooth abrasion, tooth abrasion began to occur between age is 33 and 34.Dentine sensitivity is the highest prevalence of tooth wear complications.the tooth legally effective for light treatment of dentine hypersensitivity, to severe dentine hypersensitivity efficacy not sure. Preventive adjustable teeth can effectively avoid the occurrence of severe tooth wear and its complications in this age of teeth.Dentine hypersensitivity patients in shock symptoms, 100% with enamel dentin dysplasia.Hint for these patients we should as soon as possible to crown repair or high inlay restoration of protective treatment in clinically.
