Abstract
Objective: To analyze the factors that influence the eruption chronology of primary teeth. Methods: The research theme was defined and databases and search strategies were established. The databases used were: Latin American and Caribbean Literature in Health Sciences (LILACS), International Literature in Health Science (MEDLINE) and Scientific Electronic Library Online (SCIELO). To search for the articles, descriptors indexed to the Health Science Descriptors (DeCS) were used: “Tooth eruption”; "Tooth deciduous" and "Chronology". Results: Thin foil sample of eight items, the majority of studies in Brazil (62.5%) and the rest in Nigeria, Nepal and Spain (37.5%). 75% of the articles indicated that the Lower Central Incisor was the first tooth to erupt, occurring on average at 9 months of age. Changes in chronology and the pattern of eruption may vary between individuals and contribute to early or delayed primary teeth. Among these factors, the main ones are related to nutrition, prematurity, breastfeeding, social profile, sex and the systemic conditions of each child. Final considerations: Local, systemic and maternity-related factors influence the chronology and sequence of eruption of primary teeth, making it essential to monitor the child's growth and development.
