Deciduous teeth trauma in childhood is one of the most common issues in dentistry. The most frequent types of predecessor teeth trauma are dislocations and intrusions. This is related to anatomical conditions of maxilla bone, periodontium and teeth structure. Trauma usually reffers to incisors. It can implicate tooth germ damage, due to thin bone lamina, which separates deciduous teeth roots from teeth germs. The consequences of predecessor teeth injuries depend on the child’s age who sustained injury, as well as on the stage of odontogenesis and the intensity of trauma. The aim of the work is to present long-term consequences of maxilla anterior segment trauma with regard to the age and type of trauma, and the stage of tooth germ odontogenesis. 35 patients, after the trauma at various stages of childhood, participated in our study. In every case an individual treatment plan was applied and the age of the injury alongside with the stage of odontogenesis were taken into consideration. Surgical and surgical-orthondontic treatments were applied. At younger age, the implications of trauma mainly concern the tooth crown, elder children both the crown and the root. When the trauma intensity is low, tooth crown defects such as white and brown discolorations and enamel hypoplasia may occur. The aforementioned defects require esthetic adjustments. When the trauma intensity is high, eruption disturbances may occur. Then, the proper treatment plan is to perform orthodontic-surgical tooth positioning in the dental arch. The other type of implication is crown malformation or crown and root dilaceration. These cases are indications for extraction of the distorted tooth. The age of treatment onset is significant for treatment prognosis, because root growth potential must be maintained. The difference in central incisors eruption time between 6 to 12 months, should raise concern among parents and dentists.
