Relationship of complete unilateral and bilateral cleft palate with malposition and malformation of maxillary lateral incisors

Abstract

Cleft palate is a facial deformity that allows primary and permanent teeth to be affected by anomalies such as malpositions and malformations. The lateral incisors are the most commonly affected in patients with cleft palate. The diagnosis of malposition and dental malformation is established through history taking, clinical examination, and diagnostic evaluation in the form of study models, clinical photos, and panoramic radiographs. The aim of this study was to analyze the relationship between complete unilateral and bilateral cleft palate and maxillary lateral incisor malposition and malformation. The research method is analytic cross-sectional, with the research sample consisting of 35 primary data from clinical examinations and secondary data from panoramic radiographs of pediatric patients 5-13 years old at YPPCBL RSGM Padjadjaran University, Bandung. This study looked at the clinical condition of dental anomalies and the interpretation of panoramic radiographs. Data were analyzed using Kendall Concordal analysis and Spearman rank correlation. The results showed that the impaction is the most common type of maxillary lateral incisor malposition found in complete unilateral and bilateral cleft palate. Peg shape is the most common type of maxillary lateral incisor malformation found in complete unilateral cleft palate. The highest rate of maxillary lateral incisor agenesis was found in bilateral complete cleft palate compared to complete unilateral clefts. There is a relationship between complete unilateral and bilateral cleft palate, which was statistically significant at 78% with p-value = 5.69E-32 <0.05. The conclusion of the study is there is a relationship between the unilateral cleft palate; and bilateral complete with malposition and malformation of maxillary lateral incisors.
