Abstract

This study aimed to assess whether the gender of the dental practitioner affects operative techniques in class 2 and class 5 resin composite restorations. In 2008, a nationwide survey was given to Korean dentists. Total 12,193 e-mails were distributed, 2,632 were opened by recipients, and 840 responses were collected. Of the respondents, 78.9% were male and 21.1% were female. The gender distribution in the age groups between respondents and the total population did not differ (p > 0.05). A chi-square test was used to compare technical differences between female and male dentists. A multiple logistic regression analysis was performed to assess the association between gender and operative techniques in resin composite restoration. For class 2 resin composite restoration, female dentists were 1.87 times more likely than male dentists to do multiple incremental fillings (four layers or more) and 2.72 times more likely than males to spend 30 minutes or more for the treatment (p < 0.05). For class 5 resin composite restoration, female dentists were 2.69 times more likely than their male counterparts to use a cavity base or liner, 1.83 times more likely to do multiple incremental fillings (four layers or more) and 1.63 times more likely to spend 20 minutes or more for the procedure (p < 0.05). The gender factor was influential to individual operative techniques in restorative treatment.

본 연구에서는 복합 레진을 이용한 2급/5급 와동의 직접수복에 있어서 치과의사의 성별에 따른 술식의 차이를 비교하였다. 2008년 대한치과의사협회에 등록된 치과의사 12,193명을 대상으로 이 메일을 통한 설문조사를 실시하였다. 이 메일 수신이 확인된 2,632명 중 840명이 응답하였으며 응답자의 남녀 비율은(남 78.9%, 여 21.1%) 전체 치과의사의 남녀 비율과 유의한 차이를 보이지 않았다(p > 0.05). Chi-square test 와 multiple logistic regression analysis 를 이용하여 남녀간 술식의 차 이를 검증하였다. 2급 와동 수복에서 여자치과의사는 4회 이상의 적층 분할 수복을 하는 경향이 남자치과의사에 비해 1.87배 높았으며, 술식 당 30분 이상 소요하는 경향은 2.72배 높았다(p < 0.05). 5급 와동 수복에서 여자치과의사는 베이스를 사용하는 경향이 1.83배 높았으며, 술식 당 20분 이상 소요하는 경향은 1.63배 높았다(p < 0.05). 본 설문조사에 따르면 남녀 성별에 따라 복합 레진 수복 술식의 차이가 존재하는 것으로 나타났다.
