Crown-root fracture with pulp exposure: a case report with 16-year follow-up.

A 12-year-old boy presented for dental care 35 days after he fell from his bicycle. Clinical and radiographic examinations revealed a longitudinal crown-root fracture with pulp exposure in the maxillary left central incisor. The radiograph also suggested necrosis of the maxillary right central incisor. Urgent treatment of the left central incisor involved gingivectomy followed by autogenous bonding of the tooth fragment with self-curing composite resin. Immediately after bonding, coronal access was prepared, chemical and mechanical preparation was completed, and a calcium hydroxide intracanal dressing was placed. One week after the initial appointment, endodontic treatment was initiated in the right central incisor. The root canal of the maxillary left central incisor was maintained with calcium hydroxide paste (replaced at 45-day intervals) for 1 year and then definitively obturated. At the 16-year follow-up, satisfactory periodontal, esthetic, and clinical conditions were observed, and a radiograph revealed no resorption or periapical changes.

Reattachment of fractured fragment of an anterior tooth: case report and nine-year follow-up.

This article reports the treatment and follow-up of a 10-year-old boy who had a politraumatic accident that resulted in severe displacement and fracture of the maxillary right central incisor. After clinical and radiographic examination, the tooth fragment was bonded with adhesive and the tooth crown underwent nonrigid splinting. Follow-up appointments were scheduled once a week during the first month, once during the second month, and every three months thereafter. Each follow-up appointment included a clinical examination, followed by radiographic and pulp sensitivity tests. After the fifth year, pulp necrosis was diagnosed following a sensitivity test and a periapical radiograph. Endodontic treatment was performed; the chemical-mechanical preparation and root canal fillings used calcium hydroxide paste manipulated with saline solution. The abovementioned paste was replaced twice during the first month; after that, propylenoglycol was used as the vehicle for manipulating the calcium hydroxide. The filling paste was replaced whenever the radiographic image showed resorption of the paste. The root canals were filled definitively seven years postaccident. Nine years postaccident, clinical and radiographic examination revealed a normal aspect.

Interdisciplinary approach to traumatized permanent anterior teeth: case report and 10-year follow-up.

This article presents a case report (including the 10-year follow-up) of a 10-year-old patient who suffered displacement of the maxillary right central incisor, intrusion of the maxillary left central incisor, and crown fractures to the mesial angles of these teeth as a result of dental trauma. Treatment involved an interdisciplinary approach that utilized a pediatric dentist, an endodontist, and an orthodontist.

Avaliação da eficácia de métodos de higiene bucal em bebês / Evaluation of the effectiveness of methods of buccal hygiene in babies

O presente trabalho objetivou: testar a eficácia de três métodos de higiene bucal em bebês; observar a reação dos bebês frente às técnicas testadas e conscientizar os pais da necessidade de iniciarem precocemente a higiene das bocas de seus filhos. Das técnicas analisadas, a escova com creme dental mostrou-se a mais eficiente, com relação à remoção de placa, seguida pelo uso da fralda, com água filtrada. A técnica que apresentou melhor aceitação por parte dos bebês, foi a que utilizou fralda com água filtrada
