The most common form of periodontitis is a variably progressive dynamic pathologic process that causes attachment loss, destroys the alveolar bone supporting a tooth, and terminates with tooth loss. We evaluated the loss of teeth of treated periodontal patients categorized by severity and risk.
Each of nine periodontists evaluated 100 consecutive periodontal maintenance patients. The disease severity and risk level were determined from data at the initial examination. The number of teeth lost was determined from data at the initial and maintenance visits.
A stepwise regression analysis showed that disease (P = 0.0000478) and risk (P = 0.00129) scores predicted the mean tooth loss rate. The adjusted R(2) statistic was 88.56%. The ordinal logistic regression model showed that only the disease score (P <0.0005) was significantly associated with the probability of patients losing a specific number of teeth.
Categorizing a patient by severity may be beneficial in the management of the periodontal patient. The disease score can be used to establish a criterion and target for care. For example, treatment can result in nearly no lost teeth when the severity is low, and this benefit is lost when the severity is high. The disease score provides an objective means to quickly determine severity. An increase in the disease score provides evidence that a new treatment plan is needed. Therefore, the effect of the routine use of the disease score could result in fewer patients with severe disease and reduce the number of teeth lost.
最常见的牙周炎形式是一种可变性进展的动态病理过程，它会导致附着丧失、破坏支撑牙齿的牙槽骨，并最终导致牙齿脱落。我们评估了按严重程度和风险分类的牙周治疗患者的牙齿缺失情况。
九位牙周病医生对 100 名连续的牙周维护患者进行了评估。疾病严重程度和风险水平是根据初始检查时的数据确定的。牙齿缺失数量是根据初始和维护就诊时的数据确定的。
逐步回归分析表明，疾病（P=0.0000478）和风险（P=0.00129）评分预测了平均牙齿缺失率。调整后的 R²统计量为 88.56%。有序逻辑回归模型表明，只有疾病评分（P<0.0005）与患者缺失特定数量牙齿的概率显著相关。
根据严重程度对患者进行分类在牙周病患者的管理中可能是有益的。疾病评分可用于确定护理的标准和目标。例如，当疾病严重程度较低时，治疗可以导致几乎没有牙齿缺失，而当疾病严重程度较高时，这种益处就会丧失。疾病评分提供了一种快速确定严重程度的客观方法。疾病评分的增加表明需要新的治疗计划。因此，常规使用疾病评分的效果可能会导致患有严重疾病的患者减少，并减少牙齿缺失的数量。
