Abstract
Background: The Cusp of Carabelli is a small additional cusp which is situated on the mesiopalatal surface of first maxillary molars. This nonfunctional cusp comes in many forms including furrows, ridges or pits and is collectively known as the Carabelli trait
Objective: To evaluate the frequency of the occlusal contacts between the accessory cusp of Carabelli and the opposing arch tooth among both genders in patients attending the out-patients department of Peshawar Dental Hospital, Peshawar
Methodology: This descriptive cross-sectional study was conducted on 300 subjects visiting the OPD of Peshawar Dental Hospital from October 2022 to December 2022. The sample size was calculated using WHO formula N=p(100-p)z2/d2 (Http://www.fao.orgThe age group selected for the participants was from 13-30 years. Consecutive sampling technique was used.). Articulating paper was used to assess the occlusal contacts caused by the cusp of Carabelli. The data were analyzed using SPSS version 20. Pearson’s chi square test was applied to analyze the data. P value of ≤ 0.05 was considered statistically significant.
Results: The results of the current study showed that 10.7% of the participants experienced occlusal contacts caused by the presence of their accessory cusp with the opposing arch tooth with no statistically significant difference between genders.
Conclusion: The cusp of Carabelli is the most prevailing variation found on the palatal aspect of mesiopalatal cusp of permanent maxillary first molars in a hospital-based inhabitants of Peshawar with rare occlusal contacts experienced by the patients.
Key words: Cusp of Carabelli, Maxillary permanent first molars, Occlusal contact.
背景:Carabelli尖是位于第一上颌磨牙中腭面上的一个小的附加尖。这种无功能的牙尖有多种形式,包括沟状、脊状或凹状,统称为Carabelli特征目的:评估在白沙瓦牙科医院门诊部就诊的男女患者中,Carabelli副牙尖与对侧弓牙之间咬合接触的频率。本研究对2022年10月至2022年12月在白沙瓦牙科医院门诊就诊的300名受试者进行了描述性横断面研究。样本量计算采用WHO公式N=p(100-p)z2/d2 (Http://www.fao.orgThe),年龄为13-30岁。采用连续抽样技术)。用咬合试纸评价Carabelli牙尖引起的咬合接触。数据采用SPSS version 20进行分析。采用Pearson卡方检验对数据进行分析。P值≤0.05认为有统计学意义。结果:本研究结果显示,10.7%的参与者因其副尖牙与对侧弓牙的存在而发生咬合接触,性别差异无统计学意义。结论:Carabelli尖是白沙瓦某医院常住上颌第一磨牙中腭尖腭面最常见的变异,患者的咬合接触很少。关键词:Carabelli尖,上颌第一恒磨牙,咬合接触。
