AGURTO V., Pamela; DIAZ M., Rodrigo; CADIZ D., Olga  y  BOBENRIETH K., Fernando. Oral bad habits frequency and its association with dentomaxilar abnormal development, in children three to six year old in Santiago Oriente. Rev. chil. pediatr. [online]. 1999, vol.70, n.6, pp.470-482. ISSN 0370-4106.

Oral bad habits can disturb the normal development of the orofacial system, leading to facial deformities, besides psycological and emotional problems, along with disturbances in other systems like respiratory, digestive, and learning. In Chile, the third most frequent odontological disturbance are badoclussions, secondary to many factors including oral bad habits. To resolve this problem it is necessary a strong cooperation among the health team, parents and kids. The purpose of this investigation is to make a first evaluation of the frequency of bad habits in the chilean pediatric population, and to look at the relationship between oral bad habits and the development of badoclussions. 1110 children, 3 to 6 year old from 6 colleges and 4 infants gardens of the east area of Santiago were studied. All of them showed their tonsils healthy at the begining of the study, full primary dentition and integrity of their crowns. 66% presented oral bad habits, 1878 patients, being the most frequent abnormalities: sucking (62%), oral breath (23%) and tongue interposition (15%). The objects more often sucked were the milk bottle (55%), a finger (23%) and the pacifier (15%). 57% of the kids who presented bad habits developed at least one badoclussion. The most frequent badoclussion was distoclussion (38%), cross bite (28%) and open bite (16%). A highly significant association between the presence of the bad habits and the development of badoclussions (p < 0.0001) was found. The high frequency of oral bad habits show the importance of the pediatric control in order to avoid badoclusion and oral deformities later in life
