The Prevalence of Dental Attrition and its Association with Factors of Age, Gender, Occlusion, and TMJ Symptomatology

Abstract

Dental attrition severity in 222 young adults was assessed from dental casts as the sum of the most severe facet in each arch segment. The attrition scores were compared by age, gender, bruxism awareness, prior bite adjustment, orthodontic class, maxillomandibular relationship, and temporomandibular dysfunction symptoms. Awareness of bruxism was not associated with the wear scores and should not be used to define bruxist groups. Attrition scores did not differ significantly between age groups, indicating that notable attrition, when present, often occurs early. Men had higher attrition scores than women (p less than 0.01), despite fewer signs and symptoms. Dental attrition was not associated with the presence or absence of TMJ clicking, TMJ tenderness, or masticatory muscle tenderness. Class II division 2 males had laterotrusive attrition scores lower than those of Class III (p less than 0.05). Class III females had lower incisor attrition scores than did other Angle Classes (p less than 0.05). Discernible dental attrition in a non-patient population was not associated with signs and symptoms of temporomandibular disorders, nor with the occlusal factors studied. These results are compatible with the findings in other studies that point to bruxism as a centrally induced phenomenon common to all people and unrelated to local factors.

Evaluation of the basic erosive wear examination (BEWE) for use in general dental practice

“…Erosion is one of the commonest causes of tooth wear; it has been defined as the loss of tooth substance resulting from chemical action, not involving bacteria. [6][7][8][9][10][11] Objective The basic erosive wear examination (BEWE) is a relatively new index proposed for the screening and recording of tooth wear in adults. The aim of this study was to test the validity and reliability of the BEWE.…”

Temporomandibular Disorder Awareness of Patients

“…18 Birçok çalışmada, bruksizm prevalansı genel populasyonda %50'nin üze-rinde olmakla birlikte, bruksizm farkındalığı üzerine yapılan klinik çalışmalarda bu oranın %15'e düştüğü rapor edilmiştir. [18][19][20][21] Her ne kadar diş aşınması TMD'nin tek başına işareti olmasa da, model çalışmalarında prevalans %91,5'e yüksel-mektedir. Bunun yanı sıra noktürnal elektromiyografik (EMG) kayıtlara göre bruksizm toplumun %100'ünü etkilemektedir.…”

“…Bunun yanı sıra noktürnal elektromiyografik (EMG) kayıtlara göre bruksizm toplumun %100'ünü etkilemektedir. 18 Verileri yorumlamak için, Conti ve ark. ile Silveira ve ark.nın yaptığı çalışmalardaki benzer parametreler kullanılmıştır.…”

Defining Dental Age for Chronological Age Determination

“…In literature, various methods are defined for dental age assessment that can be categorized as: visual, radiological, morphological, biochemical and histological methods [1,[18][19][20][21].…”
