Influence of surgical technique and timing of primary repair on interarch relationship in UCLP: A randomized clinical trial.

Objective: To compare dental arch relationships in children with unilateral cleft lip and palate (UCLP) between two surgical techniques for repair of cleft lip/palate and two ages of palate repair.

Settings And Sample: Dental models were taken for a group of 448 subjects at a mean age of 7 years and were evaluated by means of the Goslon Yardstick. The patients studied consisted of an initial group of 673 infants with complete UCLP randomized into 8 study groups according to lip repair procedures (Millard versus Spina techniques); palate repair procedures (von Langenbeck versus Furlow techniques); and palate repair timing (early: 9 to 12 months versus late: 15-18 months).

Delayed formation of a lower second premolar.

Delayed odontogenesis of a lower second premolar is presented in a case treated without extraction and focuses on the 7-year follow-up of the delayed tooth bud. The follow-up was initiated when the crown formation was diagnosed and was finished when the tooth erupted completely into the orthodontically provided space, which enabled the orthodontic leveling and alignment of the delayed premolar. The long follow-up indicates that delayed tooth buds may develop completely and normally.
