“…18 Premolars are not usually multirooted except the maxillary first premolar and also the furcation area in them is more apically positioned. 8 Taurodontism has also been seen to be associated with multiple other developmental disorders, 6,15 the most common of which is the cleft lip and palate. Numerous studies have evaluated the prevalence of taurodontism in different types of cleft patients in different populations and showed variable results.…”

“…Thus, a clinician has to alter his approach from the routine by using magnification, ultrasonic irrigation with 2.5% sodium hypochlorite to remove the voluminous pulp, and modified filling technique to obturate the tooth. 6 A prosthodontist has to keep in mind that the stability of a taurodont to be used as an abutment is compromised and due to lack of cervical constriction, it is also bereaved of the buttressing effect against excessive loading of the crown. Because of the apical shift of furcation, a taurodontic tooth sometimes poses difficulty in positioning the forcep beaks during extraction especially in teeth with widely divergent roots.…”

The present study aimed to assess the co-occurrence of taurodontism in nonsyndromic cleft lip and palate (NSCLP) patients in a subset of Indian population using cone beam computed tomography (CBCT). The study was a retrospective case–control kinds assessing 1500 CBCT scans over a period of 2 years; 67 scans out of 1500 showed cleft lip and palate (CLP). After fulfilling the inclusion and exclusion criteria, 38 subjects out of 67 comprised the case group; 80 randomly selected subjects constituted the control group. The first and second permanent molars in both the arches (8 teeth) of each subject were assessed for the presence and severity of taurodontism using the objective criteria. Statistical analysis was done using the χ2 test. Inter and intraobserver agreement was evaluated by Kappa statistics. 71.05% subjects showed taurodontism in case group, while 45% subjects showed its presence in control group; results being significant for both the groups. However, the comparison of number of teeth with taurodontism in the 2 groups came out to be statistically insignificant. Also no significant association of taurodontism was seen with gender or the different types of cleft ( P = .437). Hypotaurodontism was the most prevalent type. There was a higher prevalence of taurodontism in both groups which had been underestimated in the previous studies. This emphasizes the significance of the use of CBCT in detection of dental anomalies which would otherwise go undetected.
