The present prospective longitudinal study aimed to evaluate the chronology, signs and symptoms of eruption of primary lower incisors in preterm and/or low birth weight children. The sample was comprised of 46 children in follow-up at the Children's Risk Clinic (ACRIAR) at the Clinical Hospital of the Federal University of Minas Gerais. Children with a minimum age of four months in eruption stage of primary incisors and ACRIAR followed up were included. Patients with syndromes who had undergone a tooth eruption were excluded. The dependent variables were chronology and clinical signs and symptoms of tooth eruption, and were evaluated monthly by clinical exams by a trained and calibrated dentist (Kappa intra and inter-examiner> 0.81). The independent variables were prematurity and low birth weight, sex, history of breastfeeding and oral habits of the child, history of orotracheal intubation, length of stay in the Intensive Care Unit (ICU) and history of Continuous Positive Airway Pressure (CPAP). Data were analyzed using Kaplan-Meier survival analysis and the Log Rank test. Mann Whitney and Kruskal Wallis tests were used for bivariate analysis and Poisson regression with robust variance was used for multivariate analysis (p<0.05). The mean age of eruption of primary mandibular incisors was 11 months for both sexes. There was no association between gestational age and birth weight with delayed eruption (p>0.05). There was a statistically significant association between eruption and weight/length/gestational age. Children who were born small for gestational age had the eruption later than those born large for gestational age (tooth 71: p=0.030; tooth 81: p=0.017). Intubation, ICU period stay and CPAP use were not associated with chronology of eruption (p>0.05). Increased salivation, digital suction, gingival itching/irritation, and irritability were the most frequently reported eruption symptoms. In conclusion, small children for gestational age had a late eruption compared to those large for gestational age. Additionally, preterm and low birth weight was not associated with delayed eruption of the primary lower central incisors. Symptoms such as increased salivation and irritability were often associated with tooth eruption in preterm and/or low birth weight children
