“…In the present study, congenitally missing tooth was observed in 34.6% of PRS patients ( Table 1 ), which was relatively lower than Antonarakis et al 16 (42%) and de Smalen et al 17 (47.8%) but higher than Mateo-Castillo et al 18 (22.7%).…”

“…Mateo-Castillo et al, 18 in their retrospective study, reported that taurodontism was the most prevalent dental phenotype (92.7% in nonsyndromic PRS patients). However, in the present study, taurodontism was not found ( Table 1 ).…”

“…With regard to dental anomalies in PRS patients, several studies have reported a high prevalence of congenitally missing tooth and taurodontism. [16][17][18] However, the prevalence of other dental anomalies including microdontia, short root, and supernumerary tooth in Korean PRS patients remains to be investigated. Furthermore, to the best of our knowledge, no clinical demographic studies have evaluated the oral manifestations, detailed skeletodental pattern of the maxillomandibular complex, and associated anomalies in Korean pre-adolescent patients with PRS.…”

Objective To investigate the phenotypes and predominant skeletodental pattern in pre-adolescent patients with Pierre–Robin sequence (PRS). Methods The samples consisted of 26 Korean pre-adolescent PRS patients (11 boys and 15 girls; mean age at the investigation, 9.20 years) treated at the Department of Orthodontics, Seoul National University Dental Hospital between 1998 and 2019. Dental phenotypes, oral manifestation, cephalometric variables, and associated anomalies were investigated and statistically analyzed. Results Congenitally missing teeth (CMT) were found in 34.6% of the patients (n = 9/26, 20 teeth, 2.22 teeth per patient) with 55.5% (n = 5/9) exhibiting bilaterally symmetric missing pattern. The mandibular incisors were the most common CMT (n = 11/20). Predominant skeletodental patterns included Class II relationship (57.7%), posteriorly positioned maxilla (76.9%) and mandible (92.3%), hyper-divergent pattern (92.3%), high gonial angle (65.4%), small mandibular body length to anterior cranial base ratio (65.4%), linguoversion of the maxillary incisors (76.9%), and linguoversion of the mandibular incisors (80.8%). Incomplete cleft palate (CP) of hard palate with complete CP of soft palate (61.5%) was the most frequently observed, followed by complete CP of hard and soft palate (19.2%) and CP of soft palate (19.2%) ( p < 0.05). However, CP severity did not show a significant correlation with any cephalometric variables except incisor mandibular plane angle ( p < 0.05). Five craniofacial and 15 extra-craniofacial anomalies were observed (53.8% patients); this implicated the need of routine screening. Conclusions The results might provide primary data for individualized diagnosis and treatment planning for pre-adolescent PRS patients despite a single institution-based data.

“…Unilateral left cleft lip and palate appeared to be the most likely type of clefts that would show concomitant pulp chamber enlargement, most commonly in the left permanent maxillary first molars. Reina (2016) and Mateo-Castillo et al (2019) also reported higher frequency in maxillary permanent molars, in particular second molars. However, Melo Filho et al (2015) suggested mandibular molars can be more affected.…”

“…The prevalence of taurodontism that we have found in our group of 16 Klinefelter' s patients (12.5%) appears to be lower than what observed in other Klinefelter' s populations. Taurodontism seems to be associated with several other syndromes such as Down' s syndrome (24), 48,XXYY syndrome (25), Prader-Labhart-Willi syndrome (26), Wolf-Hirschhorn syndrome (27)(28), Pierre Robin syndrome (29); it is also more frequent in familial groups (5,8), in families with WNT10A defects (30) and it is a typical trait frequently found in Neanderthal teeth (17).…”

Objective: Taurodontism is a dental anomaly characterized by an enlarged pulp chamber and apycal displacement of the pulpar floor. The prevalence of taurodontism in normal population is controversial. It has been reported that taurodontism is frequently observed in Klinefelter’s patients. The purpose of this study was to assess the prevalence of taurodontism in a group of Italian Klinefelter’s patients and in a randomly selected male population of Italy and to compare the results with published data. Materials and methods: Digital panoramic radiographs of 16 Klinefelter’s patients and of 100 normal males were retrospectively studied in order to investigate the prevalence of taurodontism in these groups of patients. Results: Taurodont teeth were observed in 2 of the 16 Klinefelter’s patients (12.5%) and in 2 of 100 normal males (2.0%). Conclusions: Our results confirm the higher prevalence of taurodontism in Klinefelter’s patients compared to the normal population (12.5% vs. 2.0%). Due to the wide discrepancy of incidence of taurodontism reported in literature (0.04%-48.0% in normal population; 12.5%-88.0% in Klinefelter’s patients), we conclude that it is not possible to state which is the prevalence of taurodontism in a normal population nor among Klinefelter’s patients.
