Oral health data collected from a mail survey of an Ontario population of adults aged 18 years and over were used to conduct a preliminary investigation of the incidence and correlates of tooth loss and to explore its functional, psychological and social consequences. Of the sample of 500 dentate subjects, 10 per cent reported losing one or more teeth in the previous year. Comparisons between those with and without tooth loss showed significant differences according to age, household income and place of birth. Those subjects wearing partial dentures, possessing fewer teeth at the start of the study period, or who only attended the dentist when having pain or other trouble, were also more likely to have experienced tooth loss in the preceding year. Logistic regression analysis identified only age as a significant independent risk factor. Subjects who lost teeth were significantly more compromised in their oral functions and psychosocial behaviors, as measured by a battery of subjective oral health indicators. Whether or not these problems were pre-existing or the consequences of losing teeth during the past year cannot be determined from this study. This investigation suggests that tooth loss is still a concern for many Canadian adults, and demonstrates the importance of teeth in their overall well-being.
通过对安大略省18岁及以上成年人进行邮件调查收集的口腔健康数据，用于对牙齿脱落的发生率及其相关因素进行初步调查，并探讨其功能、心理和社会后果。在500名有牙受试者的样本中，10%的人报告在前一年掉了一颗或多颗牙齿。有牙齿脱落和没有牙齿脱落的人之间的比较显示，在年龄、家庭收入和出生地方面存在显著差异。那些戴着局部假牙、在研究开始时牙齿较少，或者只有在疼痛或有其他问题时才去看牙医的受试者，在前一年也更有可能经历牙齿脱落。逻辑回归分析仅确定年龄是一个显著的独立风险因素。通过一系列主观口腔健康指标测量，掉牙的受试者在口腔功能和心理社会行为方面明显更受影响。这些问题是先前就存在的，还是过去一年掉牙的后果，本研究无法确定。这项调查表明，牙齿脱落仍然是许多加拿大成年人关心的问题，并证明了牙齿在他们整体健康中的重要性。
