“…2A). Our results are in line with previous studies on Asian populations (5)(6)(7)(8)(9)(10)(11)(12)34), especially the Taiwanese (5)(6)(7)(8)(10)(11)(12), suggesting that a DLRs is considered to be a normal morphologic variant and can be seen as an Asiatic trait (31).…”

“…DLR typically refers to the presence of an additional root existing lingually to a distal root and is a major anatomic variant in PMFMs (5)(6)(7)(8)(9)(10)(11)(12). This morphologic characteristic has been recognized as a genetically determined racial trait (31). Considerable heterogeneity of DLR frequency has been described in previous studies (5)(6)(7)(8)(9)(10)32).…”

“…Previous studies have reported that the presence of this dental trait has been thought to be a genetically determined racial trait. In whites and blacks, the frequency of DLR is less than 5%, while in populations with ethnic Mongolian characteristics (for example, Chinese, Japanese, Korean, and Taiwanese), the frequency of DLR ranges from 5 to 30% [ 34 – 36 ].…”

Background Cone-beam computed tomography (CBCT) was used to study the root canal system of mandibular anteriors (MAs) in a Cantonese population and to evaluate the correlation between the complicated root canal configurations of mandibular lateral incisors (MLIs) and the presence of distolingual roots (DLRs) in mandibular first molars (MFMs). Methods A total of 11,376 mandibular anterior teeth were scanned by CBCT. Those whose images met the inclusion criteria were first analysed according to Vertucci's root canal configuration and then grouped based on gender, age, and side, and their effects on root canal morphology were analysed. Finally, statistical analysis was used to evaluate the correlation between the complicated root canal configurations of MLIs and the existence of DLRs in MFMs. All statistical analyses were performed by using SPSS 25.0 software. Quantitative data are presented as the mean ± standard deviation. Student’s t tests were used to calculate statistical significance. P < 0.05 was considered statistically significant. Results In MAs in the Cantonese population, all mandibular central incisors (MCIs) and MLIs had one root, and 0.37% of mandibular canines (MCs) had two roots. The most common Vertucci's root canal configuration was Vertucci I followed by Vertucci III. A total of 30.91% of MLIs and approximately 8% of MCIs and MCs have complicated root canal configurations. There were no significant differences in the prevalence of DLRs in MFMs and the incidence of complicated root canal configurations of MLIs between males and females or between the right and left teeth. However, a significant difference was found in different age groups of root canal configurations in MLIs. Moreover, significant ipsilateral and contralateral correlations between MFMs with DLRs and MLIs with complicated root canal configurations were observed on both sides. Conclusion In Cantonese population, the possibility of complicated root canal configuration in MLIs was higher, when DLR appeared in MFMs.

“…knowledge of this variation by clinician increases success rate therefore, every clinician should be familiar with abnormal variation and its prevalence among population. Distolingual root or radix entomolaries RE Considered as one of the most common genetic racial trait in mandibular molars (14) . Digital perapical radiographs have been chosen for the current study as-they are regularly used as a base for collecting diagnostic information (15) .…”

Purpose: of this cross-sectional study was to determine the proportion of permanent mandibular first molar teeth with three roots among the Egyptian population. Material and methods:In total, 479 digital periapical radiographs were screened & evaluated to get 312 samples for the study. The 312 studied subject,137 male and 175 females, aged range from 19 to 70 years. Symmetry, gender, and frequency of existence of third root in mandibular first molars were assessed and analyzed using chi square test. Two examiner evaluated the radiographic characteristics of the radix entomolaris (RE). Cohen kappa test was used to assess intraexaminer variability. Results:The prevalence of RE was 2.91 % (4/10)in male, 3.42% (6/10) in female. Total Prevalence of RE in mandibular first molar was 3.12 %. There was no significant difference regarding to gender as p = 0.862. The Prevalence RE showed no statistically significant regarding to the position either unilateral or Bilateral (p=0.342) Conclusion:The overall prevalence of the RE is 3.12% in the mandibular first in the Egyptian population.
