“…In the present study, the overall prevalence of RE was 9.23%; this is relatively higher than the other studies conducted on Indian population groups [17,18,19,20,21]. It was observed that three patients had bilateral RE presentation (1.15%), 13 cases had left RE (5%) and 5 cases had right RE (3.08%).…”

“…7 Recent Indian studies performed using intraoral periapical radiographs showed that 5.6–6.5% Indian children had three-rooted deciduous mandibular molars. 8 , 9 In Taiwan, 21–27% of the surveyed patient populations had three-rooted permanent mandibular first molars. 10 , 11 However limited information has been reported in the literature regarding the correlation between the occurrence of three-rooted deciduous mandibular second molars and three-rooted permanent mandibular first molars.…”

Background/purpose This study aimed to determine the correlation between the occurrence of three-rooted deciduous mandibular second molars and three-rooted permanent mandibular first molars in children. Materials and methods Orthopantograms (n = 977) obtained from August 2008 to December 2010 were retrospectively screened and examined. Among the 977 orthopantograms, those of 591 participants (314 boys and 277 girls; mean age, 8.7 years) with bilateral deciduous mandibular second molars and permanent mandibular first molars were studied. The gender predilection and prevalence of three-rooted mandibular molars were assessed, and the pattern of concurrence was investigated. Results The prevalence of three roots were 28.4% and 27.6% in the deciduous mandibular second molars and permanent mandibular first molars, respectively. Bilateral occurrence of three-rooted mandibular molars was almost 60% for both deciduous and permanent molars. There was a significantly greater prevalence of three-rooted mandibular molars on the right side of the mandible than that on the left side. Conclusion Deciduous and permanent molars show a similar prevalence of three roots. The presence of three-rooted deciduous mandibular second molar can strongly predict the possibility of three roots in permanent mandibular first molar.

“…The reason for the difference in the results of the mentioned studies with the present study can be attributed to the exclusion of the first and second primary molars from the target samples in the study of Nagaveni et al [ 25 ] and Tu et al [ 17 ], respectively, as well as racial diversities between Taiwanese [ 17 ], Indian [ 16 , 25 ], Korean [ 26 ], and southeast Iranian population [ 27 ].…”

“…Tu et al considered the prevalence of extra roots in only mandibular first primary molars, and it was reported to be 4.93% [ 17 ]. In a similar study conducted by Nagaveni et al, only mandibular second primary molars were examined and the total occurrence of third root among the study participants was 6.5% [ 25 ]. In another study by Srivathsa, the overall prevalence was 5.6%, of which 71.4% was related to the first primary molars and 28.6% was related to the second primary molars [ 16 ].…”

Introduction. Although primary teeth have a determinative role in development of normal occlusion, few studies about anomalies related to deciduous dentition have been conducted so far. Regarding recent improvements in common knowledge and the importance of maintaining primary teeth until eruption of succedaneous teeth, identifying the morphology of primary teeth and probable variations is of great importance to achieve optimal therapeutic outcome. This study aims to determine the prevalence of three-rooted mandibular primary molars in a population of northwestern Iran. Materials and Methods. In this descriptive cross-sectional study, periapical radiographs of patients attending private oral and maxillofacial radiology offices in the northwestern region of Iran from 2017 to 2019 were retrospectively reviewed. A total of 300 cases in the 3– 10 -year age range having bilateral periapical radiographs from mandibular primary molars were screened. First and second primary molars were observed meticulously. Gender, side of the mandible (right or left), symmetry, overall prevalence, and prevalence considering the type of molar (D or E) were recorded and analyzed. Results. Overall prevalence of three-rooted mandibular primary molars was 9.33 % ( 28 / 300 ), 92.9 % of which were unilateral. The prevalence of teeth showing supernumerary roots among all teeth examined was 2.5 % ( 30 / 1200 ). Considering symmetry and gender, the occurrence of these three-rooted primary molars did not differ significantly (respectively, p = 0.832 and p = 0.541 ). However, there was a significant relationship between the occurrence of supernumerary roots and left side for three-rooted first molars and right side for three-rooted second molars ( p = 0.021 ). Conclusion. Obtained data show that three-rooted mandibular primary molars in children of northwest region of Iran have a prevalence of approximately 10 % which urges some specific considerations in exodontic and endodontic procedures.
