    ABSTRACT: Abstract -  Intrusive luxation is a kind of traumatic injury characterized by an axial displacement of the tooth toward the alveolar bone. Its main causes are bicycle accidents, sports/recreational activities, and falls or collisions. Treatment strategies include waiting for the tooth to return to its position, immediate surgical repositioning, and repositioning through dental traction by orthodontic devices. In order to decide which treatment to follow, the degree of root formation, the patient's age, and intrusion severity should be taken into consideration. This study aimed to report a 10-year follow-up of two patients that suffered permanent incisor (PI) traumatic injury who had a similar root development (incomplete rooting) but different results. In the first case, the treatment of choice was follow-up. The patient showed gingival alteration and root resorption of tooth 21. Calcium hydroxide therapy and root canal filling were performed twice because of not attending callback. After finishing the endodontic treatment, follow-up visits showed no abnormalities. In the second case, the treatment of choice was watch and wait to the teeth 11 and 21. After 7 months spontaneous eruption of both teeth was detected. Radiographic examination showed atypical root formation and almost completely pulp canal obliteration, 8 years later. In the follow-up, visit after 10 years was observed complete crow and pulp canal obliteration. It was concluded that PI intrusion treatments are good intervention alternatives, as they proved to be successful after a 10-year follow-up period.

    ABSTRACT: The purpose of this study was to analyze the association between dental trauma and occlusal traits in the primary dentition. Five hundred and one 24- to 71-month-old children, attending both private and public schools in Pelotas, Rio Grande do Sul, Brazil, were included. Clinical examinations were performed at each school. Occurrence of dental trauma was assessed using the Andreasen and Andreasen classification. Occlusal characteristics used in this study were: overjet; open bite; overbite; anterior crossbite; crowding and rotated teeth occurrence; and canine class. The occlusion type was classified according to the World Health Organization. A questionnaire was sent to parents to obtain socioeconomic data. Descriptive statistics were used, as well as chi-square tests (for heterogeneity or linear trend; P ≤ .05) and Fisher's exact test. The prevalence of dental trauma was 40% (95% confidence interval=35-44). Of all children examined, 20% showed normal occlusion, 42% mild malocclusion, and 38% moderate/severe malocclusion. Dental trauma was associated with overjet ≥ 3 mm (P=.02), overbite ≥ 3 mm (P=.01), and canine class (P=.04). Children bearing mild or moderate/severe malocclusion presented greater dental trauma (P<.01). The findings of this study emphasize the importance of preventing dental trauma, especially in children presenting increased overjet, overbite, or canine Class II.

    ABSTRACT: To estimate the prevalence of traumatic injury in primary dentition among children aged 12-71 months old, as well as to evaluate the distribution of traumatic injuries, type of trauma and associated factors. After the research project approval by the Ethics Research Committee, a cross-sectional study was carried out including 571 preschool children--both from public and private schools--in the city of Pelotas, Southern Brazil. Data were collected by means of anterior teeth examination, and by the administration of a structured questionnaire to parents. The classification proposed by Andreasen & Andreasen was used, and crown discoloration and fistula were added to this criterion. The prevalence of dental trauma was 36.6% (95% CI 32.7-40.5), with no significant differences between boys and girls. Trauma were more frequent among older children (P = 0.001). No associations were found for maternal schooling, income and type of school. The most frequent trauma was enamel fracture, and the most affected tooth was number 61. A significant statistical association was observed between the presence of dental trauma during clinical examination and parental report of trauma occurrence. The percentage of parents who looked for dental treatment was higher among children from private schools (P = 0.001). The most frequent place of occurrence was home, and the most frequently reported etiology was child's own-height fall. Dental trauma in primary teeth is characterized as an accident that occurs due to the children's development stage, even when they are cared for by mothers of higher schooling and income. Parents should search for assistance right after trauma occurrence to minimize sequelae.

    ABSTRACT: The aim of this report is to present a clinical case of impaction of a maxillary left central incisor in a mixed dentition caused by the presence of an odontoma as well as a review of the pertinent dental literature. Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiologic development. A delay in time between the exfoliation of a deciduous tooth and the eruption of its permanent successor may be related to a disorder known as dental retention. This occurs when tooth eruption does not occur within a normal time frame, the tooth is not present in the dental arch, and there is no potential for eruption due to the presence of a completely formed root or when the homologous tooth has been erupted for at least six months with complete root formation. A 10-year-old boy in the mixed dentition stage presented with an impacted maxillary left central incisor due to the presence of an odontoma. Treatment included the surgical removal of the lesion and the follow up of the spontaneous eruption while a partial fixed appliance was used to recover the space of the missing tooth. Since spontaneous eruption failed to occur within the expected time frame, surgical exposition of the crown and bonding of an orthodontic appliance for traction was done to facilitate eruption. The incisor was integrated to the dental arch without any root or periodontal sequelae. The treatment was considered a success, since both health and aesthetics of the smile were recovered. The importance of the clinical and radiographic diagnosis of the retention of a permanent tooth associated with a pathological entity should be emphasized. The participation of a multidisciplinary team to accomplish the appropriate treatment of such patients is extremely relevant because of the esthetic and functional ramifications of a missing anterior tooth as well as the psychological well-being of the individual.
