Prevalence, severity and etiology of dental wear in patients with eating disorders

Abstract

Objective:The purpose of this study was to evaluate the prevalence, distribution and associated factors of dental wear among patients with eating disorders (EDs).Materials and Methods:An epidemiological cross-sectional survey was conducted by trained, calibrated examiners, using the dental wear index. The sample was composed of 30 patients with EDs (experimental group – G1) and 30 control patients without current or previous history of EDs (G2). A questionnaire was used to assess the etiological factors of dental wear. The univariate analyses using the Chi-square (χ2) test were used to compare the tooth wear prevalence between groups according to the surface and tooth (P > 0.05).Results:The dental wear was similar for both group; however, the G1 presented more moderate wear in molars when compared with G2 (P = 0.048). The majority of EDs patients related have one or more oral habits (n = 26; 86.6%) and only 13.4% (n = 4) affirmed did not have oral habits. The etiological factors of tooth wear related with dental wear were biting objects (P = 0.04) and pain in temporomandibular disorders (P = 0.03).Conclusion:The highest prevalence of dental wear was observed in the molars teeth. Differences in the extent and pattern of dental wear were found in an individual, emphasized the relevance of clinical parameter.

Dental aspects of purging bulimia

“…In most studies involving bulimic patients, it is very difficult to reach a representative sample because large number of patients are hiding their disorder, they are young and not interested in cooperation 12,18 . This is the reason why most of the modifying factors affecting DE and caries can not fully be investigated and confirmed in bulimic patients 12 .…”

“…Questionnaire was designed as set of questions that resembles the ones that were used in other original scientific papers with similar subject matter, considering all data that seemed to be anamnesticly significant for analysis of presence, localization and degree of DE, tooth decay and life habits in bulimic patients 18,19 . The clinical examination included intraoral inspection.…”

“…The age of participants was selected according to the scientific findings referring to the age when bulimia usually occurs (age [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35], and control group was gender and age matched. The average age of bulimic patients is 24.6 ± 4.42 years and 83.3% of them were students, which corresponds to the fact that bulimia is most commonly present in university population 13 .…”

“…DE in bulimic patients were subject of numerous studies and meta-analyzes and great majority of them pointed the fact that DE are significantly more often present in patients suffering ED compared to healthy subjects 3,21,29,30 . Purging as repeated behavioral pattern increases risk of dental erosion appearance up to 5-8.5 times, and their presence 2.6-5.5 times, so DE can be detected in 90% of purging bulimics, while these lesions are not typical for non-purging types of eating disorders 14,18,30 . These findings are confirmed by studies that prove DE presence in 63%-86% of purging bulimics, and none of non-purging patients 31,32 .…”

Prevalência e fatores associados ao bruxismo em universitários: um estudo transversal piloto

“…15 Neste estudo, o diagnóstico de bruxismo foi baseado no critério da Academia Americana de Medicina do Sono: 11 queixa de apertar ou ranger os dentes combinada com pelo menos uma das seguintes condições: desgaste dentá-rio anormal, sons associados com bruxismo e desconforto na musculatura mandibular. Foram analisadas as variáveis: ocorrência do bruxismo, prevalência de desgaste dentário e a relação entre bruxismo e sinais e sintomas de disfunções temporomandibulares.…”
