最近的研究表明牙周炎是全身性疾病的一个原因，据报道，牙周袋暴露于细菌生物膜的表面积为50 cm（2）至200 cm（2）。由于典型的人类牙列（不包括第三磨牙）的根表面积为75 cm（2），这些估计似乎太大了，本研究的目的是将线性牙周探测测量与牙龈表面积（DGES）联系起来。DGES包括存在于健康中的沟上皮和结合上皮，以及存在于牙周炎中的任何居间袋上皮。从临床测量中估计DGES的公式来自根表尿素的荟萃分析，根长度的公布值，以及剩余根表面积百分比与剩余根长度百分比相关的研究。这些公式：应用于美国成年人口的调查，退伍军人事务部（VA）牙科纵向研究，和访问牙周病医生的个人人口。没有牙周炎的人的典型DGES为5 cm（2）。在牙周炎患者中，三个样本的平均DGES范围为8 cm（2）（范围为1 cm？至29 cm（2））至20 cm（2）（范围为2 cm（2）至44 cm（2））。得出的结论是，牙周炎个体的平均DGES范围为8 cm（2）至20 cm（2），远小于目前假设的50 cm（2）至200 cm（2）的范围。
Recent studies implicating periodontitis as a cause of systemic diseases have reported that the surface area of periodontal pockets exposed to bacterial biofilm ranges from 50 cm(2) to 200 cm(2). Since the root surface area of the typical human dentition (excluding 3rd molars) is 75 cm(2), these estimates appear too large, The goal of this study was to relate linear periodontal probing measurements to the dentogingival surface area (DGES). The DGES comprises both the sulcular and junctional epithelium, present in health, as well as any intervening pocket epithelium present in periodontitis. Formulas to estimate the DGES from clinical measures were derived from a meta-analysis of root surface ureas, published values of root length, and a study that related the percent remaining root surface area to the percent remaining root length. These formulas: were applied to a survey of the adult US population, the Veterans Affairs (VA) Dental Longitudinal Study, and a population of individuals visiting a periodontist. Individuals without periodontitis had a typical DGES of 5 cm(2). Among individuals with periodontitis, the mean DGES in the three samples ranged from 8 cm(2) (ranging from I cm? to 29 cm(2)) to 20 cm(2) (ranging from 2 cm(2) to 44 cm(2)). It was concluded thai the mean DGES among individuals with periodontitis ranges from 8 cm(2) to 20 cm(2), considerably smaller than the range of 50 cm(2) to 200 cm(2) currently assumed.
