Hypoplasia Assessment Index in Cleft Lip and Palate Subjects

The aim of this study was to assess hypoplasia in permanent maxillary anterior dentition. The sample for this study consisted of 60 subjects divided into two groups: Group 1 consisted of 30 subjects with complete unilateral cleft lip and palate. Group 2 consisted of 30 subjects with complete bilateral cleft lip and palate (both males and females). Informed consent was taken from all patients. Inclusion criteria for cleft lip and palate subjects included: Complete repaired lip and palate, non-syndromic unilateral and bilateral cleft lip and palate both males and females with age 14 year-16 year (mean age cleft group14.6 year ±.73 year). Exclusion criteria included: Cleft lip and palate subjects with systemic diseases, incomplete repaired palate, open fistulas, developmental or acquired craniofacial muscular deformities, autoimmune conditions, syndromes, endocrine abnormalities, neurological problems, any previous history of orthodontic treatment and signs and symptoms of temporomandibular disorders. Clinical examination was performed under natural light with a dental mirror and dental probe. The presence or absence of lesions, their location, and their characteristics were recorded following the Simplified Index described by Silber man et al two digit system scoring. The results showed highest 52% cases of obvious hypoplasia with caries and roughly round or oblong lesion. It was concluded that hypoplasia is frequently related to maxillary anterior segment both in unilateral and bilateral cleft lip and palate.
