OBJECTIVE: The objective of the study was to present the prevalence of taurodontism in the permanent dentition in individuals with Laurence-Moon/Bardet-Biedl syndromes (LM/BBS). METHODS AND PARTICIPANTS: Thirty-nine individuals were studied, which comprises the whole population of known LM/BBS patients in Norway. Data were collected retrospectively. Panoramic radiographs (OPG) were evaluated to document taurodontism. RESULTS: Taurodontism was found in 82.9% of the individuals with LM/BBS. The second mandibular molars had the highest (72.3%) prevalence of taurodontism and the first mandibular molars the lowest (58.2%). CONCLUSION: This study suggests that taurodontism should be included as a minor diagnostic criterion for the Laurence-Moon/Bardet-Biedl syndromes (LM/BBS).
