To evaluate the prevalence of various gingival biotypes and to corroborate gingival thickness and gingival biotypes across tooth type, site, and gender.
A cross-sectional study was conducted across systemically healthy subjects. A systematic clinical evaluation for gingival biotypes and gingival thicknesses was recorded by modified Iwanson's gauge, to the nearest 0.1 mm, probing the gingival sulcus at the midfacial aspect of maxillary and mandibular central incisors and first molars. All measurements were made across a total of 920 sites in 115 subjects (69 female and 46 male) based on gingival transparency and were statistically analyzed.
A significant agreement on the reproducibility of the measurements was noted. The median overall gingival thickness was recorded at 0.75 mm with interquantile difference of 0.39 mm. The thin biotype variant showed across the ranges of 0.3 to 0.6 mm of gingival thicknesses and thick biotype variant across the ranges of 1.0 to 1.2 mm, with more prevalence in anterior and posterior site respectively. Moreover, for gingi-val thickness of 0.7 mm, the probe visibility showed tendency toward both thin/thick biotype variant in both anterior and posterior segments. The disposition of male participants toward thick biotype and female participants toward the thin biotype variant has been noted.
Within the limitations of the current study, our data support the traditional hypothesis of two main gingival biotypes as distinguishable by gingival transparency. In addition, we provide evidence of existence of intermediate biotypes with respect to gingival thickness. These findings can be utilized as objective guidelines for determination of biotype and can be implicated in many dental operative procedures. How to cite this article: Rathee M, Rao PL, Bhoria M.

评估不同牙龈生物型的患病率，并证实不同牙型、部位和性别的牙龈厚度与牙龈生物型之间的关系。
对全身健康的受试者进行了一项横断面研究。使用改良的岩松氏测量仪，在距上颌和下颌中切牙及第一磨牙的唇面中点牙龈沟处进行探测，以最接近0.1毫米的精度记录牙龈生物型和牙龈厚度的系统临床评估结果。基于牙龈透明度，在115名受试者（69名女性和46名男性）的总共920个部位进行了所有测量，并进行了统计分析。
测量的可重复性得到了显著一致的结果。总体牙龈厚度中位数记录为0.75毫米，四分位数间距为0.39毫米。薄生物型变体的牙龈厚度范围为0.3至0.6毫米，厚生物型变体的牙龈厚度范围为1.0至1.2毫米，分别在前牙区和后牙区更为常见。此外，对于牙龈厚度为0.7毫米的情况，在前牙段和后牙段，探针可见度显示出向薄/厚生物型变体的趋势。已注意到男性参与者倾向于厚生物型，而女性参与者倾向于薄生物型变体。
在本研究的局限性范围内，我们的数据支持了传统的假设，即通过牙龈透明度可区分两种主要的牙龈生物型。此外，我们提供了关于牙龈厚度存在中间生物型的证据。这些发现可作为确定生物型的客观指导原则，并可应用于许多牙科手术程序。如何引用本文：拉西 M，拉奥 PL，博里亚 M。印度北部年轻有牙人群牙龈生物型的患病率：一种生物测量方法。《国际临床儿科牙科学杂志》2016；9(2)：104 - 108。
