There is a considerable intra and inter-individual variation in both width and thickness of the facial gingiva. As the attached gingiva is an important anatomic and functional landmark in the periodontium, the identification of gingival biotype is important in clinical practice since differences in gingival and osseous architecture have been shown to exhibit a significant impact on the outcome of restorative therapy. Hence, the aim of this study was to determine the variation in width and thickness of facial gingiva in the anterior segment with respect to age, gender and dental arch location.
120 subjects were divided into three age groups: The younger age group (16-24 years), the middle age group (25-39 years) and the older age group (>40 years) with 20 males and 20 females in each group. The width of the gingiva was assessed by William's graduated probe and the thickness was determined using transgingival probing in the maxillary and mandibular anterior segment.
It was observed that the younger age group had significantly thicker gingiva but less width than that of the older age group. The gingiva was found to be thinner and with less width in females than males. The mandibular arch had thicker gingiva with less width compared to the maxillary arch.
In the present study, we concluded that gingival thickness and width varies with age, gender and dental arch location.
面部牙龈的宽度和厚度在个体内和个体间存在相当大的差异。由于附着龈是牙周组织中一个重要的解剖和功能标志，牙龈生物型的识别在临床实践中很重要，因为牙龈和骨结构的差异已被证明对修复治疗的结果有显著影响。因此，本研究的目的是确定前牙段面部牙龈的宽度和厚度在年龄、性别和牙弓位置方面的变化。
120名受试者被分为三个年龄组：年轻年龄组（16 - 24岁）、中年年龄组（25 - 39岁）和老年年龄组（>40岁），每组20名男性和20名女性。使用威廉斯刻度探针评估牙龈宽度，并通过在上颌和下颌前牙段进行龈下探诊确定厚度。
观察到年轻年龄组的牙龈明显比老年年龄组厚，但宽度更小。发现女性的牙龈比男性更薄且宽度更小。与上颌牙弓相比，下颌牙弓的牙龈更厚但宽度更小。
在本研究中，我们得出结论，牙龈厚度和宽度随年龄、性别和牙弓位置而变化。
