Abstract

OBJECTIVES

To compare re-treatment choices for MOD amalgam or resin composite restorations with or without cusp fracture among dentists in Kuwait.

METHODS

A random sample of 158 dentists completed a questionnaire designed to obtain socio-demographic, educational and work-related information and their choices for re-treatment of four scenarios of failed restorations on lower first molars: 1. MOD amalgam restoration; 2. MOD composite restoration; 3. MOD amalgam restoration with cuspal fracture; 4. MOD composite restoration with cuspal fracture. Re-treatment options were: re-treating with amalgam; re-treating with composite; placing an onlay; or, placing a crown. For the purpose of analysis, responses were dichotomized into re-treatment with a direct or indirect restoration.

RESULTS

For cases 1 and 2, most participants chose to re-treat with amalgam restoration and for cases 3 and 4, most chose to place an indirect restoration. In general, an increased tendency towards the indirect option was associated with increased age, being a male and being a specialist. Tendencies to place an indirect restoration did not differ between cases 1 and 2 (P=1.0) or cases 3 and 4 (P=0.317), although the tendency to do so was significantly greater in case 3 than 1 (P=0.000) and case 4 than 2 (P=0.000).

CONCLUSIONS

The variation noted among dentists regarding their stated choices for re-treating failed posterior restorations appeared to be associated with gender, education and experience factors. A tendency towards indirect restorations was seen when the restoration is associated with a fractured cusp.

摘要

目的

比较科威特牙医对有或无尖折的MOD银汞合金或树脂复合材料修复体的再治疗选择。

方法

随机抽取158名牙医完成一份问卷，旨在获取社会人口统计学、教育和工作相关信息，以及他们对下颌第一磨牙四种修复失败情况的再治疗选择：1. MOD银汞合金修复体；2. MOD复合树脂修复体；3. 有尖折的MOD银汞合金修复体；4. 有尖折的MOD复合树脂修复体。再治疗选项包括：用银汞合金再治疗；用复合材料再治疗；放置高嵌体；或放置全冠。为便于分析，将回答分为直接或间接修复的再治疗。

结果

对于情况1和2，大多数参与者选择用银汞合金修复体进行再治疗，对于情况3和4，大多数选择放置间接修复体。总体而言，选择间接修复的倾向增加与年龄增长、男性身份和专科医生身份有关。情况1和2（P = 1.0）或情况3和4（P = 0.317）之间放置间接修复体的倾向没有差异，尽管情况3比情况1（P = 0.000）和情况4比情况2（P = 0.000）这样做的倾向明显更大。
