To analyse tooth loss and to evaluate the longevity of healthy teeth and teeth compromised by diseases and influenced by therapy as well as that of oral implants.
On the basis of an electronic and manual search using key words for survival, success, longevity of teeth, longevity of implants, epidemiology, periodontally compromised, endodontically compromised, risk for tooth extraction 49 full-text articles were identified to construct a traditional review. Among these, six systematic reviews addressing longevity were found.
Tooth loss is a complex outcome, it is influenced by the extent of dental caries and its sequelae and/or the presence or absence of periodontitis as well as the decisions taken by dentists when evaluating possible risk factors for rendering successful therapy. In addition, tooth loss is related to behavioural and socio-economic factors and associated morbidity and cultural priorities. Generally, teeth surrounded by healthy periodontal tissues yield a very high longevity (up to 99.5% over 50 years). If periodontally compromised, but treated and maintained regularly, the survival of such teeth is still very high (92-93%). Likewise, endodontically compromised, but successfully treated devital teeth yield high survival and success rates. The survival of oral implants after 10 years varies between 82% and 94%.
Teeth will last for life, unless they are affected by oral diseases or service interventions. Many retained teeth thus may be an indicator of positive oral health behaviour throughout the life course. Tooth longevity is largely dependent on the health status of the periodontium, the pulp or periapical region and the extent of reconstructions. Multiple risks lead to a critical appraisal of the value of a tooth. Oral implants when evaluated after 10 years of service do not surpass the longevity of even compromised but successfully treated natural teeth.
分析牙齿缺失情况，评估健康牙齿、受疾病影响及治疗影响的牙齿以及口腔种植体的存留时间。
通过电子检索和手工检索，使用与牙齿存留、成功、存留时间、种植体存留时间、流行病学、牙周受损、牙髓受损、拔牙风险相关的关键词，确定了49篇全文文章以构建传统综述。其中，发现了6篇关于存留时间的系统综述。
牙齿缺失是一个复杂的结果，它受到龋齿及其后遗症的程度和/或牙周炎的有无以及牙医在评估成功治疗的可能风险因素时所做决定的影响。此外，牙齿缺失与行为和社会经济因素以及相关的发病率和文化优先事项有关。一般来说，被健康牙周组织包围的牙齿存留时间很长（50年内高达99.5%）。如果牙周受损，但经过治疗并定期维护，这些牙齿的存留率仍然很高（92 - 93%）。同样，牙髓受损但成功治疗的无活力牙齿也有较高的存留率和成功率。口腔种植体10年后的存留率在82%至94%之间。
牙齿可以终生存留，除非受到口腔疾病或治疗干预的影响。因此，许多留存下来的牙齿可能是一生积极口腔健康行为的指标。牙齿的存留时间很大程度上取决于牙周、牙髓或根尖周区域的健康状况以及修复的程度。多种风险导致对牙齿价值的关键评估。使用10年后评估的口腔种植体甚至没有超过即使受损但成功治疗的天然牙齿的存留时间。
