Dentists must be aware of the relationship between the child's age at the time of trauma to the predecessor tooth and the type of sequel to the successor tooth in order to diagnose, monitor, and treat the sequel properly.

NTST is neither reliable nor valid for detecting ankyloglossia that may interfere with breastfeeding in newborns.

This methodology can be used to induce AAWSLs in human dental enamel but surface erosion has to be taken into account when performing CSMH test.

Objective The aim of this study was to determine the frequency of pulp canal obliteration (PCO) after traumatic dental injury (TDI) of primary anterior teeth and to investigate its relation with the related variables. Methods This retrospective study has been done with dental records of patients selected from the Paediatric Dental Trauma Clinic between 2006 and 2016. Those who had PCO in the primary anterior teeth and were aged 0-108 months at the time of trauma were considered eligible. Data related to patients and TDI, such as sex, the child’s age at the time of trauma, aetiology, affected teeth, the child’s age at the time of the eruption of the permanent successor as well as the presence of crown discoloration were extracted from the dental records. Results Among the 483 children with traumatised teeth, 14.9% had PCO and the most of them exhibited crown discoloration. The average age of the children at the time of the trauma was 38 months and the most common aetiology of the TDI was falls. The average time for the beginning of the PCO process was 13.5 months. There was no statistically significant association between the child’s age at the time of trauma and the types of TDI, PCO and the presence of crown discoloration. Conclusions The frequency of PCO was relatively low though the presence of crown discoloration was considerable. There was no association between the child’s age at the time of trauma and the studied variable.

Background: This paper aims to describe a case report about dentigerous cysts related to trauma in the primary teeth.Case report: An eight-year-old boy attended the Pediatric Dental Trauma Clinic. He had a delay in the eruption of the tooth 11 and when he was four years old suffered a trauma in the tooth 51. The radiograph showed a dentigerous cyst involving the tooth 11. The lesion was treated through enucleation and the permanent tooth erupted. Conclusions:A correlation was observed between the dentigerous cyst, trauma in the deciduous incisor and the successor teeth. Early diagnoses as well as clinical and radiographic follow-ups of traumatized primary teeth are important to minimize possible sequelae in the successor teeth.
