OBJECTIVE: The purpose of the study was to investigate the distribution of various oral cleft types and the occlusion status of patients with cleft lip and/or palate (CLP) attending dental treatment in the College of Dentistry at King Saud University, Riyadh, Saudi Arabia. METHODOLOGY: The present study was retrospective cross-sectional study done by reviewing the cleft lip and/or palate patients' dental records, and study models. All CLP patients with deciduous, mixed and permanent dentitions were included. A special form was designed exclusively for collecting the required information of every subject. Gender, age, type of cleft and dentition, and occlusion were statistically analyzed using proportional Z test (P<0.05). RESULTS: A total of 165 subjects (109 males (65.5%) and 57 (34.5%) females), constituted the study population. The prevalence among gender was statistically significant (P<0.0005). Among the 165 subjects, 35 (21.2%) were <6 years, 72 (43.6%) were between 7 and 12 years, and 58 (35.2%) were >12 years. Most of the subjects 125 (75.8%) had combined cleft lip and palate (P<0.0005). No statistical difference between the prevalence of unilateral cleft 87 (52.7%) and bilateral clefts 56(33.9%) (P=0.263). In subjects with primary dentition, mesial-step molar relationship was the most common 27(84.4%) (P<0.0005), while class I molar relationship was the most common type in subjects with mixed or permanent dentitions 85(58.2%) (P<0.0005). Combination of posterior and anterior cross-bites were found in the sample; right side 81(29.8%), left side 86(31.6%) and anterior 105(38.6%).. Decreased overbite 101(70.1%) and overjet 98(67.6%) were more commonly found (P<0.000).. CONCLUSION: Various types of CLP were studies and results showed that male subjects were affected more than females. Majority of subjects had the cleft lip and palate type. Anterior and posterior cross-bites, as well as decreased overbite and overject were found in most of the sample. Results indicate the need for interceptive orthodontic in CLP subjects
