Supernumerary tooth associated with cleft lip and palate

Location and Presence of Permanent Teeth in a Complete Bilateral Cleft Lip and Palate Population

“…Several authors explain that the dental lamina of the lateral incisor is thought to split, resulting in what some authors describe as supernumerary teeth. 6,7 Cleft site supernumerary teeth were found in 10.5%. This is more than the 0.73% of patients having a cleft site supernumerary tooth in a nonsyndromic CUCLP population 1 and 1-3% of noncleft patients who have supernumerary teeth.…”

“…While research has characterized dental anomalies in nonsyndromic complete unilateral cleft lip and palate (CUCLP) patients, [1][2][3][4] no investigations have specifically assessed location and presence of permanent teeth in a nonsyndromic complete bilateral cleft lip and palate (CBCLP) population. Comparing and interpreting previous studies is difficult because of the inclusion of mixed cleft samples, 5 the lack of well-defined criteria for tooth determination especially around the cleft area, 6 not specifying exclusion criteria such as related syndromes associated with dental agenesis, 7,8 and not specifying the completeness of the cleft. 9,10 Further, reports on complete CLP patients do not mention excluding patients with Simonart's bands.…”

Abnormalities of Maxillary Anterior Teeth in Chinese Children with Cleft Lip and Palate

“…In addition, there is a higher number of supernumerary teeth in this region because the tooth buds of the permanent lateral incisors are susceptible to modification, or division, possibly being divided by the cleft (Millhon and Stafne, 1941;Schulze, 1953;Ngai et al, 1965).…”

Mesiodistal size of deciduous teeth in subjects with unilateral cleft lip and palate

“…The patients with cleft lip and palate had a lot of anomalies of teeth (14). Striking deviations from the normal size, shape and form of the lateral incisors in the region of cleft lip and alveolus have been observed in most instances and in majority of the reports (15–18). A supernumerary deciduous lateral incisor is more common than a permanent one (19, 20), whereas absence of the permanent tooth germ is noticeably more prevalent than absence of the deciduous one (19).…”
