Influence of dummy use on the eruption chronology of temporary dentition

Abstract

Introduction: The literature currently shows several studies linking the use of a dummy with the development of malocclusion. However, a possible relationship between non-nutritive sucking habits, namely dummy use, and changes in eruption chronology has not yet been studied. Aim: To establish a relationship between the use of a dummy and the development of changes in the eruption chronology of the temporary dentition in children aged between 3 and 6 years. Material and methods: The study took place in two phases. The first phase involved collecting information on non-nutritive sucking habits through a questionnaire given to the child's legal guardians. In the second phase, an intraoral examination was carried out by the researcher, with the aim of collecting clinical data relating to the chronology of eruption appropriate to the age group. Results: The sample consisted of 62 children, 75.8 per cent of whom (n=47) use or have used a dummy. The average age of eruption of the first temporary tooth was approximately 7 months, and the average age of eruption of the last temporary tooth was approximately 29 months. There was a statistically significant difference between the use of a dummy and the age of eruption of the last temporary tooth, i.e. the age of the last temporary tooth was higher in children who did not use a dummy. Conclusion: The age of eruption of the last temporary tooth is lower in children who use or have used a dummy.
