目的分析9,805例银汞合金、复合材料、玻璃离子、树脂改良玻璃离子及其他充填物在恒牙修复中的更换原因。设计根据患者的年龄、性别、疾病类型、临床医生的性别、经验和实践环境对资料进行细分。结果继发龋的临床诊断是所有类型牙体替换的主要原因，其次是牙体折断，尤其是大块折断，与患者年龄无关。整体变色是成人更换树脂基材料的第三大常见原因，但很少发生在18岁及以下的青少年中。置换原因与患者性别无关。基于临床医生性别的亚组显示，女性临床医生比男性临床医生更常诊断继发性龋齿。除此之外，两种性别临床医生的替换原因相似。根据临床医生毕业后的年数对职业进行细分，结果形成了小组。最年轻的一组临床医生诊断相对更多的继发龋，无论是银汞合金和复合材料的牙釉质比最有经验的一组。结论临床诊断继发龋是所有类型龋病更换的主要原因。
OBJECTIVE The analysis of reasons for the replacement of 9,805 amalgam, composite, glass ionomer, resin modified glass ionomer and 'other' restorations in permanent teeth in general dental practice. DESIGN The data were subdivided on the bases of age and gender of the patients, the types of restorations and the clinicians' gender, experience and practice setting. RESULTS The clinical diagnosis of secondary caries was the main reason for replacement of all types of restorations studied, followed by fracture of restorations, especially bulk fracture, irrespective of patient's age. Bulk discoloration was the third most common reason for replacement of resin based materials in adults, but it rarely occurred in adolescents 18 years and younger. The reasons for replacement of restorations were not associated with the gender of the patients. Subgroupings based on the clinicians' gender showed that female clinicians diagnosed secondary caries more often than male clinicians. Otherwise, the reasons for replacements were similar for both genders of clinicians. Subdivision of restorations based on the years since graduation of the clinicians resulted in small groups. The youngest group of clinicians diagnosed relatively more secondary caries both for amalgam and composite restorations than the most experienced group. CONCLUSION The clinical diagnosis secondary caries was the main reason for replacement of all types of restorations studied.
