Factors associated with subjective need for orthodontic treatment among Finnish university applicants

Abstract

Subjective orthodontic treatment need and associated factors were studied in a sample of 226 young Finnish adults. The subjects, applicants to enter the University of Helsinki, were interviewed immediately after their entrance examination. A need for treatment was felt by 14% of the subjects. For 47% of those expressing such a need their reason was appearance only, and for 25% it was both appearance and their ability to chew. Among subjects who reported a visible dental irregularity, 38% were dissatisfied with their dental appearance, and 25% felt the need for orthodontic treatment. Women were more often dissatisfied with their dentition than men. Subjective need for treatment was significantly associated with perceived visible dental irregularity and infrequent socializing but not with orthodontic treatment in childhood, pattern of dental attendance, or district of residence. Of various perceptions of anterior teeth, irregularly and wrongly positioned teeth were most often connected with treatment need.
