Long term results of primary tooth autotransplantation are scarce but the procedure in this case report could be considered as a temporary space maintainer for the treatment of a patient with a lost permanent incisor under 10 years of age. Success of primary tooth autotransplantation may be affected by several factors, such as case selection, extra oral time, surgical and endodontic procedures.

Objective: Identifying the characteristics of soft-tissue profiles in 3-5 year old children. Methods: Children that participated in the study were selected from the 6 major districts of Ankara. In the selected schools,3-5 year old 1513 children with primary dentition were examined and profile photographs were obtained. Facial convexity angle (FCA) and Total facial convexity angle (TFCA) were measured from profile photographs.Results: The mean values for the total facial convexity (145.9° ±4.2) and facial convexity(165.3° ±4.5) angles were determined. FCA and TFCA were significantly influenced by primary second molar terminal plane relationship. Conclusion: Finding of this study may be used as clinical references for pediatric dental patients and also, the significant relationship between soft tissue profile and primary occlusion is important for orthodontic diagnosis and treatment of pediatric dental patients.
