【摘要】 目的:评价上前牙区角化龈宽度和牙龈厚度的关系是否为正相关。方法:选取50例20~32岁的患者(其中男性24例,女性26例),采用牙髓探针和数控游标卡尺对右侧上颌尖牙、侧切牙和中切牙的角化龈宽度和牙龈厚度进行测量,并对数据进行统计学分析。结果:侧切牙的平均角化龈宽度最宽,中切牙次之,尖牙最窄;中切牙的平均牙龈厚度最厚,侧切牙次之,尖牙最薄。男性与女性之间的角化龈宽度和厚度差异无统计学意义。上颌尖牙、侧切牙及中切牙的角化龈宽度和厚度的相关性具有统计学意义。结论:对于20~32岁的患者,上前牙区尖牙、侧切牙和中切牙的角化龈宽度和厚度之间的关系为正相关。更多还原

【Abstract】 Objective The aim of this study was to evaluate whether there is a positive correlation between the width of the zone of gingival keratinized tissue and its thickness. Methods Maxillary right canines,lateral incisors,and central incisors of 50 patients(24 men, 26 women) between the ages of 20 and 32 years were examined.Using an endodontic spacer with a rubber cursor and a digital caliper of 0.01 mm resolution,the values of the width of the zone of gingival keratinized tissue and gingival thickness were obtained. Results It was observed that the lateral incisor has the largest mean zone of gingival keratinized tissue(5.45±1.013)mm,followed by the central incisor(4.51±1.03)mm and canine(4.28±1.37)mm The mean gingival thickness was greater in the central incisor(1.19±0.23)mm,followed by the lateral incisor(1.08±0.28 mm)and canine(0.87±0.34)mm.No statistically significant difference was verified for the mean width of the zone of gingival keratinized tissue and gingival thickness between men and women.A positive correlation between gingival thickness and width of the zone of gingival keratinized tissue was observed in the maxillary canine(Pearson r=0.421,P <0.05,lateral incisor(Pearson r=0.387,P <0.05),and central incisor(Pearson r=0.489, P <0.05). Conclusion In patients 20 to 32 years of age,there was a positive correlation between gingival thickness and width of the zone of gingival keratinized tissue for the maxillary right canine,lateral incisor,and central incisor.更多还原
