Treatment Of Apical Periodontitis Of Bilateral Mandibular Dentition And Investigation Of Incidence Of Taurodontism

Objectives:To report the treatment of bilateral mandibular taurodontism apical periodontitis.Through statistical analysis of the discovery rate and distribution characteristics of taurodontism,it provides further evidence for the diagnosis and treatment of clinical taurodontism.Methods:Clinical examination,imaging examination,diagnosis,and further treatment of apical angioplasty,root canal treatment,inlay restoration,etc.,and regular follow-up observation,for the whole mouth of other teeth during the treatment Conduct medical treatment.Through retrospective investigation of radiology imaging data from January to February 2018 in the Stomatological Hospital of Jilin University,a total of 1937 oral panoramas were collected to calculate the incidence and distribution characteristics of taurodontism samples.Statistical analysis was performed using SPSS analysis,P<0.05 was statistically significant.Results:The patient’s bilateral mandibular taurodontism were treated,the apical periodontitis inflammation disappeared,the roots developed,the roots were well filled,and the inlays were repaired.The statistical survey found that there were 136 patients with taurodontism,the prevalence rate was 7.02%,62 males(3.2%),74 females(3.82%),Of the 7748 molarsexamined,454(5.85%)were taurodontism,295(3.80%)in the maxillary molars and 159(2.05%)in the mandible molars(P<0.05),maxillary first molars 184(2.37%),maxillary second molars 111(1.43%),mandible first molars32(0.41%),mandible second molars127(1.63%);The prevalence of hypotaurodontism,mesotaurodontism and hypertauro-dontism was 294(64.8%),107(23.6%)and 53(11.6%).Conclusion:Accurate clinical examination and imaging examination are the key factors in the diagnosis and endodontic treatment of taurodontism,and they are more challenging during the treatment.The statistical survey showed that the prevalence of taurodontism was low.There was no significant difference between male and female,first molar and second molar.A statistically significant difference(p<0.05)was observed in the prevalence of taurodontism in maxillary molars compared to mandibular molars.
