Rare diseases pose a particular challenge in provision of oral health care. Most do not have standardized guidelines for oral health care management. This lacuna is magnified in diseases that exhibit dental morphologic anomalies in addition to other systemic findings. Bardet-Biedl syndrome (BBS), a nonmotile ciliopathy of monogenic, autosomal recessive character, is one such disease that has remained an enigma for the oral health care provider. The fact that BBS patients exhibit systemic comorbidities involving the endocrine, renal, respiratory, genitourinary, ophthalmic and cardiovascular systems, as well as cognitive disorders and obesity, a broad spectrum of oral manifestations may be encountered. This review encompasses the insights into the disease, its ethology, pathophysiology, systemic and oral manifestations, diagnosis, medical management and oral health care provision guidelines. The oral health care professional stands a better chance at providing effective and safe oral health care to BBS patients armed with this state-of-the-art knowledge and update.
