This systematic review sought scientific evidence (in the literature) that trauma in the primary incisors cause sequelae in permanent successors. Also this work verified whether there was a relation between the presence and type of sequelae in permanent teeth with the child's age at the time of injury and type of trauma. Electronic databases, including the PubMed, Scopus, The Cochrane Library, LILACS, and Web of Science were used to search for original articles up to June 2013. Prospective and retrospective studies that assessed the association of trauma in deciduous incisors and developmental disturbances in permanent successors were selected. Two authors independently reviewed and extracted the data from the included studies. A methodological quality assessment evaluation of the selected studies was performed. The search retrieved 258 citations. Initially, 19 studies fulfilled the selection criteria; however, one (1) was excluded, leaving 18 for the final selection. Despite some limitations in the study designs were observed, especially the lack of a control group in most studies, the evidence found suggests that individuals with trauma in their primary incisors have more developmental disorders in the permanent successors than individuals without a previous trauma. Furthermore, the younger the child is at the time of injury, the more frequent and more severe are the sequelae to the permanent successor incisors. More severe traumas such as intrusion and avulsion are associated to more serious developmental disorders. These results should be analyzed carefully because very few studies evaluated had a control group.
Background
Enamel‐dentin fracture causes impact on the oral health‐related quality of life (OHRQoL) of children.
Aim
To evaluate the impact of treatment of crown fracture involving enamel and dentin (CFED) in the permanent dentition on the OHRQoL of children and adolescents (C/As) and their families.
Design
This prospective clinical study included C/As between 8 and 14 years who presented anterior CFED treated thought direct composite resin restoration. Their parents/caregivers (P/Cs) were also invited to take part of the study. The quality of life was evaluated thought the Child Perceptions Questionnaires (CPQ8‐10 and CPQ11‐14), Parental‐Caregiver Perceptions Questionnaire (P‐CPQ), and Familiar Impact Scale (FIS), applied before and 3 months after the restorative procedure. T test for dependent samples and Wilcoxon test were applied(P < 0.05).
Results
Of 32 C/As included, 30 completed the study. The treatment of CFED reduced the negative impact in OHRQoL of C/As (CPQ8‐10 P = 0.0065; CPQ11‐14 P = 0.0486; P‐CPQ, P = 0.0259), specially for “oral symptoms” (CPQ8‐10, P = 0.0003; P‐CPQ, P = 0.0455) and “emotional well‐being” (CPQ11‐14, P = 0.0431). Concerning the families’ perceptions, the treatment did not influence OHRQoL both in terms of the domains and total FIS score (P > 0.05).
Conclusion
Restorative treatment of CFED increases the OHRQoL of C/As but not influence the OHRQoL of their families.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
