Objetivo: O objetivo deste estudo foi verificar a relação entre a utilização de chupeta e o desenvolvimento da oclusão em dentição decídua e avaliar fatores como o tipo de chupeta e o tempo de utilização.
Materiais e Métodos: A população-alvo foi constituída por crianças entre os 3 e os 5 anos de idade, que frequentavam três escolas do concelho de Lisboa numa amostra total de 161 crianças. O estudo foi realizado através de um questionário com 16 perguntas entregue aos encarregados de educação e observações à cavidade oral de cada participante. Nas observações foi medido o overjet, overbite, a relação oclusal do canino decíduo e do 2º molar decíduo, a presença de mordida aberta anterior e de mordida cruzada posterior. Os dados foram posteriormente analisados no programa SPSS versão 21.
Resultados: As crianças que utilizaram chupeta apresentaram uma prevalência de relação oclusal do canino decíduo classe II de 19,4%, de relação oclusal do 2º molar decíduo de distal step de 1,7%, de overjet ≥ 4mm de 17,2%, de overbite ≥ 4mm de 23,2%, de presença de mordida posterior cruzada de 14,5% e de presença de mordida aberta anterior de 18,7%. Obtiveram-se resultados estatisticamente significativos que relacionaram a utilização de chupeta durante 36 ou mais meses com a relação oclusal do canino decíduo direito (p=0,048), com a relação oclusal do 2º molar decíduo esquerdo (p=0,047) e com a presença de mordida aberta anterior (p<0,001).
Conclusões: A utilização da chupeta demonstra alterações ao nível da dentição decídua. O fator com maior importância não é o tipo de chupeta ou o número de horas diárias que é utilizada, mas sim a duração em meses da utilização.
Objective: The objective of this study was to ascertain the relationship between a pacifier sucking habit and the development of the occlusion in deciduous teeth while evaluating other factors such as the type of pacifier and the duration of the habit. Materials and Methods: The participants of this study were children between 3 and 5 years of age that attended three different schools in Lisbon and comprised a total of 161 children. The study consisted of a questionnaire with 16 questions delivered to the parents and intra- oral observations of each participant. In the observations the following criteria were observed: overjet, overbite, primary canine relationships, primary second molar relationships, presence of anterior open bite and posterior crossbite. The clinical data was then handled in the program SPSS version 21. Results: The children that had a pacifier sucking habit presented with a prevalence of primary canine relationship class II of 19,4%, primary second molar relationship distal step of 1,7%, overjet ≥ 4mm of 17,2%, overbite ≥ 4mm of 23,2%, presence of posterior crossbite of 14,5% and presence of anterior open bite of 18,7%. Statistically significant results were obtained relating the usage of pacifier for 36 or more months with the right primary canine relationship (p=0,048), left primary second molar relationship (p=0,047) and the presence of anterior open bite (p<0,001). Conclusions: A pacifier sucking habit leads to alterations in the deciduous teeth. The factor that holds most importance isn’t the type of pacifier or the number of daily hours of use, but the duration in months of the habit.
