Influence of Conservative or Invasive Treatments on the Occurrence of Sequelae in Permanent Successors After Injuries in the Support Tissues of Incisors Deciduous Teeth: A Cohort Study.

Objective: To assess the influence of conservative or invasive treatments on the appearance of sequelae in permanent successor teeth (SPT) after injuries in the support tissues of anterior deciduous teeth (ISTDT).

Methods: This cohort study accompanied 52 children with ISTDT up to the complete eruption of the permanent successor to investigate the presence or not of SPT. Trauma was clinically evaluated according to the International Association for Dental Traumatology. Sex, age at the time of trauma (ATT), type and severity of trauma, sequelae in anterior deciduous teeth (SDT), treatment type (conservative-without exodontia/ invasive-with exodontia), seeking care (immediate/late), and the caregiver's education level (CEL) were collected. Regression models were performed (p = 0.05).

Results: Of the children (ATT = 3.6 ± 1.5 years), boys (52/57.1%) were the majority. The teeth (n = 91) injuries were lateral luxation (26/28.6%), intrusion (22/24.1%), concussion (20/22.0%), subluxation (19/20.9%), and extrusion (4/4.4%), that affected only incisors. Most teeth (63/69.2%) received late care, presented SDT (62/68.1%) and were treated conservatively (73/80.2%). There was no association of sex (p = 0.611), SDT (p = 0.705) and seeking care (p = 0.800) with SPT. The treatment type did not influence the SPT occurrence (p = 0.923), independent of the ATT, trauma severity and the educational level of the caregiver. The lower the ATT (p = 0.026) and the more severe the trauma (p = 0.009), the higher the number of SPT.

Conclusion: The treatment type of anterior deciduous teeth, mainly considering incisors, did not influence the appearance of SPT, which leads us to always choose the most conservative treatment, independent of the child's age, the injury severity, and the caregiver's educational level.
