Abstract :

Introduction: Pacifier, a wide spread habit in our country. The main use is to ease the calm in a restless or irritable child. There is no consensus among Chilean pediatricians in withdrawal prescription. At two years of age, anatomic sequelae could be identified, such as a dental malocclusion syndrome: anterior open bite. Aim: To assess the prevalence of anterior open bite at two years of age and pacifier influence. Methods: 82 Children, median age of 24 months (23-27), were assessed in an outpatient clinic at two years of age, throughout a 15 months period. Occurrence of open bite and use of pacifier was recorded. Pacifier influence was evaluated through a casecontrol study. Statistical analysis was conducted with Epi Info 3. Results: Open bite was observed in 53.7% of children (47/82, 53.7% vs. 35/82, 43.7%, NS) and use of a pacifier in 61% (50/82 vs. 39%, 32/82, p<0.05). Open bite was recorded in 97.9% of children exposed to pacifier and 2.1% in those unexposed (46/47, 97.9% vs. 1/47, 2.1%, p<0.01). Risk of malocclusion in exposed children was 92% (80.6-97.3) vs. 3.1% in unexposed (0.0-17.1), p<0.01. Risk difference between both groups was 88.9% (79.2-98.5). OR (CI 95%) for anterior open bite in children using pacifier at two years is 356 (38.03-3342), p<0.0001. Conclusion: Children exposed to a pacifier at two years of age have a high risk of anterior open bite. More studies are needed to know the real dimension of this problem. Nevertheless, it should be discouraged after one year of age.
