Effects of traumatic dental injuries to primary teeth on permanent teeth - a clinical follow-up study

Abstract

Children who sustain traumatic dental injuries should be followed up regularly for an early diagnosis and treatment of possible DSP.

Clinical and radiographic sequelae to primary teeth affected by dental trauma: a 9-year retrospective study

“…Injuries that promote the displacement of the tooth tend to exhibit necrosis, accompanied by periapical radiolucency, because of the irreversible traumas of the vascular supply and periodontal ligament. 6,7,8,9,10,30 Necrotic pulp is an excellent growth culture for microorganisms, which may gain entry to the pulp after an additional injury, through a ruptured periodontal ligament (i.e. intrusive luxation), enamel-dentin cracks (i.e., enamel-dentin fracture, and more serious enamel, dentin and pulp fracture) or from the blood stream, by anachoresis.…”

“…5,6,7 Knowledge of post-injury sequelae allows establishing the best way to treat and prevent possible complications. 8 declaration of interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

Supernumerary teeth formation following subluxation of primary incisors

“…Nevertheless, even minor TDIs are of considerable importance as they may lead to unexpected consequences . Furthermore, there appears to be a relationship with the age of the child—in that the younger the child at the time of injury the more severe the sequelae are to the permanent incisors . Typically after a mild luxation injury, parents are warned of these effects but the majority of these mild injuries have a good prognosis …”

“…It is commonly accepted that there is a possibility of effects on the permanent teeth as a result of TDI to the primary dentition, due to the close relationship between the apex of the root of the injured primary tooth and the underlying permanent tooth germ. [9][10][11][12][13][14] The more commonly occurring effects of the permanent dentition subsequent to a mild luxation injury include enamel defects, altered or delayed eruption and localized rotations. [9][10][11][12][13][14] Nevertheless, even minor TDIs are of considerable importance as they may lead to unexpected consequences.…”
