Snoring and Development of Primary Dentition
Objectives: The aim was to examine association between snoring and development of primary dentition. It was hypothesized that non-snoring children have more optimal development of primary dentition than snoring children.
Methods: Material consisted of 32 snoring and 19 non-snoring children recruited as subsample from multi-professional Finnish Child Sleep study on importance of sleep from social, cognitive and emotional perspectives studied from birth onwards. Children considered to snore were identified based on written report of caregiver. A child was classified as snorer if he/she reported to snore ≥3 nights/week at age of 8 months. Occurrence of snoring was verified in a phone call by physician. At 30 months (primary dentition just completed) clinical orthodontic examination was made at Oral and Maxillofacial Unit, Tampere University Hospital, Finland. Examination included sagittal relationship of 2nd primary molars (mesial step/distal step/flush), overjet (increased≥3mm), overbite (open bite≤0mm, deep bite≥3mm), crowding (yes/no) and lateral crossbite (yes/no). Differences between occlusal characteristics in the two groups were tested with Fisher`s exact test.
Results: Despite tendency that in the non-snoring group there were less children with increased overjet, open bite and crowding, statistical analysis did not reveal significant differences between non-snorers and snorers in studied occlusal characteristics (p>0.05).
Conclusions: Snoring in young children is considered to be abnormal and early/first sign of sleep-disordered breathing. Within the limitation of small sample size and short follow-up, hypothesis is not supported. Present findings suggest that non-snorers did not have more optimal development of early primary dentition than children snoring ≥3 nights/week.
