“…25 However, a study conducted by Bhavyaa et al reported a frequency of cusp of Carabelli to be 90.6% in deciduous maxillary second molars among 3-4 years old children 22 while the same authors conducted a meta-analysis which showed that the cusp of Carabelli was found in 59% of the overall participants. 18 The participants of the current study did not show a significant difference in gender distribution of the cusp as shown by p value 0.140 (Table 1) which is similar to the findings of Arbab et al 10,11 and Zafar et al 25 whereas other studies recruited on our local population 9 showed male predominance. Cusp of Carabelli rarely causes occlusal contacts with the opposing arch tooth as shown by frequency in the contemporary group of 10.6% (Table 2).…”

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.

“…Careful observation and examination of the tooth's crown and cervical morphology are essential. Molars with extra roots often exhibit a bulbous crown appearance, additional cusps, and axial surface protrusions, with the tooth's cervical outline being palpable with a periodontal probe [ 19 ]. Compared to the contralateral left upper first molar, the affected tooth presented with a more pronounced Carabelli's cusp and a sixth cusp (Figure 3 ).…”

Maxillary first molars exhibit considerable anatomical variation, with a single palatal root being the most common occurrence, while two palatal roots are notably less frequent. This case report details the endodontic treatment of a maxillary first molar with two separate palatal roots. It highlights the critical importance of recognizing these anatomical variations and their unique challenges during endodontic procedures. This report emphasizes the essential role of advanced diagnostic methods, such as cone-beam computed tomography, and the use of microscopic techniques in identifying and treating such cases.

“…Characteristics stem from the interplay between genetic and environmental elements. It has been proposed that a population-level visualization of the trait's frequency is possible [5].…”

“…The most notable characteristics were the shoveled incisor, peg-shaped laterals, cusp of Carabelli, radix entomolaris, and dilaceration. In a research on the non-metric characteristics of posterior teeth among the Kerala population [5], 17.78% of the population who showed the Carabelli trait also presented with Dryopithecus groove in the letter "y" pattern. In a study, 40.5% of the Carabelli trait and 68.2% shoveling of incisors were discovered locally in Bangalore, Karnataka [1].…”

“…Due to the large mineralized content of the tooth, which makes it steadfast, these non-metric dental qualities have the benefit that their morphological characteristics stay steady unless disturbed by extrinsic factors (particularly dental caries, wasting diseases, trauma, and aesthetic treatments). Therefore, these can be effectively employed in racial identification, which is useful in identifying the person through the antemortem dental record [5].…”

This study aims to evaluate the non-morphological traits of the South Indian population. IntroductionDental morphological traits, also known as non-metric dental traits, exhibit variation in appearance both within and between groups. The study analyzed the non-metric traits among the South Indian population, as few variants can be grouped within the population. Materials and methodsA total of 500 extracted tooth samples were collected. The dental non-metric traits that were evaluated are the cusp of Carabelli (CC), Talon's cusp (TC), shoveled incisor (SI), peg-shaped lateral incisor (PL), protostylid (PR), Dryopithecus pattern groove (DP), hypoconulid (HY), parastyle (PA), multiple parastyle (MPA), paracone (PC), Bushman's canine (BC), interruption groove (IG), tuberculum dentale (TD), tuberculum intermedium (TI), radix entomolaris (RE), fusion (F), radiculous premolar (RP), dilaceration (D), dens evaginatus (DE), and enamel pearl (EP). ResultsOut of 20 dental non-metric traits that were evaluated in the study, 14 traits were identified to be common within the population. The prevalence were as follows: cusp of Carabelli (52%), shoveled incisor (8.2%), pegshaped lateral incisor (7.4%), parastyle (0.8%), multiple parastyle (0.2%), Bushman's canine (0.4%), interruption groove (2.2%), tuberculum intermedium (0.6%), radix entomolaris (39.6%), fusion (2.8%), radiculous premolar (0.2%), dilaceration (58.2%), dens evaginatus (1.2%), and enamel pearl (0.8%) among the South Indian population. ConclusionThe current study was discovered to have more Carabelli traits, shoveled incisors, radix entomolaris, and dilaceration than other non-metric features. This shows that these characteristics are more prevalent in the South Indian population, which could be one of the strategies used to validate human identification in a forensic context.
