Reasons for Extraction of Permanent Teeth in General Dental Practices in Tehran, Iran

Abstract

Objectives: The aim of this survey was to investigate the primary reason for extraction of permanent teeth, its correlations with age, gender and education level, as well as identify the important predictors for dental caries in general dental centers in Tehran, Iran. Subjects and Methods: The study was conducted over a period of 6 months; its population consisted of 1,382 patients, aged 9-95 years, who underwent tooth extraction. There were 673 (47.8%) male and 709 (51.3%) female patients. The frequency distribution was calculated using the χ² test, ANOVA and t test for differences in mean number of extracted teeth and the logistic regression model to evaluate the variables associated with reasons for tooth extraction. Results: A total of 2,620 teeth were extracted from the 1,382 patients. The highest rate (36.9%) of extraction occurred for those 41-60 years old. Males comprised 48.7% of patients but had more teeth (1,470, 55.3%) extracted than females (1,150, 43.9%). Nine hundred and thirty-six (67.7%) patients had incomplete secondary education or less. Tooth loss due to caries was 51%; periodontal disease was 14.4%; supernumerary and tooth impaction 13.9%. There was a significant association between patient characteristics (age, gender and education level) and number of teeth extracted. Conclusion: Dental caries and periodontal disease were the main reasons for tooth extraction in Tehran, Iran.

Condição de saúde bucal e motivos para extração dentária entre uma população de adultos (20-64 anos)

“…This confirms the findings of the study in Family Health Units in Campina Grande, state of Pernambuco 29 , which showed caries and pain as the most reported reasons. However, these findings differ from studies with clinical insight, because they refer to conditions evaluated by professionals and not by individuals, being caries and periodontal disease the most prevalent reasons in these studies 1,7,30 . In the age group of young adults (20-44 years old), the other reasons variable appeared with high prevalence, and can be explained by the dental extractions performed with orthodontic indication.…”

“…This refers to the understanding that when the periodontal and restorative preventive procedures in primary care are not sought, there is progression of oral diseases and restriction of treatment 7,31 options. This data was also verified in the study with patients who donated the extracted teeth to a bank of human teeth of Curitiba, state of Paraná 32 , because most of those being interviewed claim to have searched for dental service only once before the decision of tooth extraction, i.e., the same day in which the procedure was carried out.…”

“…Although in recent decades Odontology has followed a more conservative philosophy, and dental extraction has been considered a last treatment option by the dental surgeon, in some cases it becomes the only option 7 . Teeth extraction is a reflex of the oral disease experiences throughout life, mainly caries and periodontal disease, which have a complex etiology with biological, social and behavioral risk factors 8 .…”

“…We believe that the findings from the population we evaluated support this result. Thus, Jafarian and Etebarian (23) emphasized that periodontal disease-related tooth extraction was not observed in individuals younger than 20; rather, periodontal disease-related tooth extraction emerges as people age.…”

“…Permanent teeth are extracted for various reasons such as dental caries, orthodontic reasons, periodontal disease, impacted teeth, failed dental treatments, pre-prosthetic considerations etc. [7]. Criterias which are taken into consideration before any extraction are tooth mobility, prosthetic planning ,severity of attachment loss, furcation involvement , endodontic-periodontal lesion, radiographic bone loss ( more than 50 % ) , grossly carious teeth [8].…”
