Objective
To evaluate oral health related quality of life (OHRQoL) in Saudi subjects with ectopic canine, severe crowding and Class I normal occlusion and to assess the differences among different orthodontic treatment modalities [OTM] for baseline, 1-day and 28-day after fixed orthodontic treatment.
Materials and Methods
The study sample comprised 32 subjects with ectopic canine who were attending orthodontic clinics at the college of Dentistry. Subjects were equally grouped in to 4 based on OTM. Each participant was assessed for OHRQoL using the Oral Health Impact Profile, English version (OHIP-16). Initial comparison of baseline data of ectopic canine subjects was done with severe crowding (>8mm) and Class I normal occlusion with the matched number and aged subjects in later groups. Also, comparison of OHIP-16 scores among 4 OTM, baseline, 1-day and 28-day after treatment were done.
Results
OHIP-16 scores of ectopic canine, severe crowding and Class I normal occlusion group was 33.06, 33.09 and 26.43 respectively. Subjects with ectopic canine and severe crowding reported a significantly greater negative impact on the embarrassment, avoid smiling and lack of self-confidence however, overall OHRQoL score was insignificant. OHRQoL (total OHIP-16 score and score for each domain) have no significant changes among 4 OTM group (P >0.05). Significant dissimilarities in OHIP-16 scores were apparent with respect to treatment time.
Conclusion
Untreated malocclusion has a significant negative impact on OHRQoL. The greatest negative impact was seen in the several domain 1-day after treatment however, gradual improvement noted 28-day after treatment irrespective of 4 different OTM.
