Treatment planning in the presence of congenitally absent second premolars: a review of the literature

One of the most common dental anomalies encountered by the pediatric dentist is the congenital absence of second premolars. Once diagnosed, the appropriate treatment necessitates the formu-lation of a comprehensive treatment plan, which is dependent upon a number of factors. Consid-erations include: the condition of the deciduous molar, dental and skeletal relationships, dental age of the patient, willingness of the patient to undergo extensive dental treatment and financial con-siderations. Approaches to the management of congenitally missing premolars have been described in the literature, including the more recently available option of dental implant place-ment. The objective of this paper is to present a review of the literature with emphasis on the con-siderations needed for appropriate treatment planning when the practitioner is confronted with this diagnostic challenge.
