Abstract
Purpose: The aim of the present was to assess the association between MIH and tooth agenesis (TA) in orthodontic patients from the Federal University of Rio Grande do Norte, Natal, Brazil.
Methods: A cross-sectional study was performed to evaluate the presence of MIH and TA in a sample of 371 pretreatment orthodontic records from patients aged 9-18 years. Statistical analyses were performed using the Chi-square and Fisher's exact tests, and logistic regressions.
Results: There was a statistically significant association between the prevalence of tooth agenesis and MIH. A higher percentage of third molar agenesis, maxillary premolar agenesis, and mandibular second premolar agenesis was observed among children with MIH-affected teeth. Patients with MIH had a 2.43 times greater chance of third molar agenesis, and a 5.88 times higher likelihood of mandibular premolar agenesis.
Conclusion: There is a weak association between MIH and TA. Furthermore, the presence of hypomineralised molars increases the risk of tooth agenesis.
期刊介绍：
The aim and scope of European Archives of Paediatric Dentistry (EAPD) is to promote research in all aspects of dentistry for children, including interceptive orthodontics and studies on children and young adults with special needs. The EAPD focuses on the publication and critical evaluation of clinical and basic science research related to children. The EAPD will consider clinical case series reports, followed by the relevant literature review, only where there are new and important findings of interest to Paediatric Dentistry and where details of techniques or treatment carried out and the success of such approaches are given.
