DESCRIPTION: This application describes three related studies of tooth fracture, a condition that affects an estimated five percent of adults annually. Despite its relatively frequent occurrence, the phenomenon has not been examined in any detail. Consequently, there are no direct estimates of the incidence of this condition. In addition, risk indicators for tooth fracture are poorly understood. Finally, the distributions of treatments fractured teeth receive, and the short-term outcomes of these treatments are completely unknown. This profound lack of information notwithstanding, a substantial portion of re-restoration in the nation s dental practices consists of placing crowns for the purpose of preventing tooth fracture, accounting for estimated expenditures of one billions dollars annually. The proposed studies examine tooth fracture in two adult populations-- enrollees in a dental HMO in Portland, OR, and army personnel stationed at Ft. Hood, TX. At both sites, preliminary estimates of the incidence of tooth fracture overall and by tooth type will be established by noting all tooth fracturing in these populations over periods of 6 and 3 months, respectively. Approximately 400 fracture events will be recorded at each site. A group of risk indicators for the complete fracture of a cusp of a posterior tooth will be examined in identical 12-month case-control studies. At each site, 400 cases will be selected together with 400 matched control teeth from the same patients, and 400 partially matched control patients. Differences in exposure for a variety of clinical, behavioral, demographic, and utilization variables will be determined. The severity of fractures and short-term outcomes of treatment for fractures are determined from incidence and case-control study data and analysis of port-fracture treatment. The information on risk indicators, incidence, severity and short-term outcomes that will result from this study is crucial for subsequent evaluation of approaches to the prevention of tooth fracture. Not only do dentists have no information upon which to base specific absolute and/or risk estimates for individual patients, but also the profession lacks the information upon which to base assessments of the appropriateness of current approaches to the prevention of fracture.

描述：本申请描述了三项有关牙齿的研究。 骨折，这种情况影响了大约5%的成年人， 每年。 尽管这种现象发生得比较频繁， 没有被详细检查过。 因此，没有直接的 估计这种情况的发生率。 此外，风险指标 对牙齿骨折的认识还很不清楚。 最后， 治疗骨折的牙齿接受，这些短期的结果， 治疗方法完全未知。 这种信息的极度缺乏 尽管如此，该国的大部分重建工作 牙科实践包括放置牙冠， 牙齿骨折，估计花费10亿美元 美元每年。 拟议中的研究调查了两个成年人群的牙齿骨折， 在波特兰，或牙科HMO的注册者和驻扎在 英尺德克萨斯州胡德市。 在这两个地点， 将通过记录所有 这些人群在6个月和3个月的时间内牙齿断裂， 分别 每一次将记录大约400起骨折事件， 绝佳的价钱 一组风险指标的一个尖的完全骨折的一个 将在相同的12个月病例对照研究中检查后牙。 每个研究中心将选择400例病例和400例匹配对照 来自相同患者的牙齿，以及400名部分匹配的对照患者。 各种临床、行为、人口统计学， 并将确定利用率变量。 骨折的严重程度， 骨折治疗的短期结果由发生率确定 病例对照研究资料及端口骨折治疗分析。 关于风险指标、发生率、严重程度和短期风险的信息 这项研究的结果对以后的研究至关重要。 评价预防牙折的方法。 不仅 牙医没有具体的绝对和/或 风险估计为个别病人，但也缺乏专业 作为评估目前 预防骨折的方法。
