There are few reports in the literature regarding estimates of the occurrence of tooth fractures. Most studies have assessed tooth fractures in people seeking dental care, which may underestimate the incidence of the problem.
This study sought to estimate the incidence and prevalence of cusp and restoration fractures, as well as root fragments in participants in the Florida Dental Care Study, a diverse representative sample of community-dwelling residents of four north Florida counties made up of people who seek dental care regularly and those who do not. Participants received a dental examination and an in person interview at baseline and at a 24-month follow-up session.
At least 20 percent of the participants were diagnosed as having bulk restoration fractures, cusp fractures or root fragments at the baseline visit. At the 24-month follow-up session, 26 percent of the participants had at least one new occurrence of these problems. Of those subjects presenting with tooth fracture, 25 percent had multiple teeth affected. African-Americans and people who sought care on a problem-oriented basis experienced twice the rate of cusp fracture and a higher rate of root fragments as did those who sought care on a regular basis. These data represent consecutive prevalence estimates rather than the true incidence, in that fractures that occurred after baseline may have been treated in the intervening 24 months. Thus, these data represent "lower-bound" incidence estimates.
These results suggest that restoration fractures, cusp fractures and root fragments are a significant dental health problem, and that selected segments of the population are at greater risk of developing these problems.
These data are useful for dentists in understanding the magnitude of the problem and the potential progression of fractures and root fragments.
关于牙齿骨折发生率的估计，文献报道较少。大多数研究评估的是寻求牙科治疗的人群中的牙齿骨折情况，这可能低估了该问题的发生率。
本研究旨在估计佛罗里达牙科保健研究参与者中牙尖和修复体骨折以及牙根碎片的发生率和患病率，该研究是佛罗里达州北部四个县社区居民的多样化代表性样本，由定期寻求牙科治疗的人和不寻求牙科治疗的人组成。参与者在基线和24个月的随访时接受了牙科检查和面对面访谈。
在基线检查时，至少20%的参与者被诊断患有大面积修复体骨折、牙尖骨折或牙根碎片。在24个月的随访时，26%的参与者至少出现了一次这些问题中的新情况。在出现牙齿骨折的受试者中，25%有多个牙齿受到影响。非裔美国人以及以问题为导向寻求治疗的人，其牙尖骨折发生率是定期寻求治疗者的两倍，牙根碎片发生率更高。这些数据代表的是连续患病率估计值，而非真实发生率，因为基线后发生的骨折可能在这期间的24个月内得到了治疗。因此，这些数据代表的是“下限”发生率估计值。
这些结果表明，修复体骨折、牙尖骨折和牙根碎片是一个严重的牙齿健康问题，特定人群发生这些问题的风险更高。
这些数据有助于牙医了解该问题的严重程度以及骨折和牙根碎片的潜在进展情况。
