Orthodontic Status and Association with Oral-Health-Related Quality of Life-A Study of 16-Year-Old Norwegians with a Cleft Lip and Palate.

The study revealed an association between severe cleft diagnosis, missing teeth, misaligned teeth, negative overjet, and poor OHRQoL, but a statistically significant association was found only between OHRQoL and poor intermaxillary sagittal relations (unfavorable profile). To improve OHRQoL among patients with clefts, there is a need for an individual follow-up and prioritization of oral healthcare.
