Intentional Re-implantation-a Viable Treatment Option

Intentional re-implantation is a procedure in which a tooth is intentionally extracted and then reinserted into its own socket for various treatment modalities. In this case report, we discuss a case of intentional re-implantation as a treatment option for failed root canal treatment with broken instrument in the apical 1/3rd of a maxillary first molar. A follow up for 2 year revealed the patient to be asymptomatic, the tooth to be sound and functional with no evidence of root resorption.

Avaliação de cavidades apicais realizadas com pontas ultrassônicas lisas, diamantadas e combinação de ambas / Evaluation of apical cavity preparation with ultrasonic, stainless steel, diamond coated lips and both

OBJETIVO: O objetivo deste trabalho foi avaliar, por meio do microscópio clínico e eletrônico devarredura, as paredes de cavidades apicais, as irregularidades produzidas com as pontas ultrassônicas diamantadas,lisas e com a combinação de ambas. MATERIAL E MÉTODO: Dezoito dentes pré-molaresinferiores de humanos, com apenas um conduto, foram apicetomizados e, no ápice, foram realizadascavidades para obturação retrógrada divididas em três grupos: grupo 1: cavidades preparadas com pontaultrassônica lisa; grupo 2: cavidades preparadas com ponta ultrassônica diamantada e grupo 3: cavidadespreparadas, iniciando com a ponta diamantada e seguida pela lisa. As paredes das cavidades foramobservadas inicialmente sob microscópio clínico e, a seguir, os ápice foram seccionados, metalizados eanalisados no microscópio eletrônico de varredura, atribuindo-se-lhes os seguintes escores: 1 - adequada;2 - regulares e 3 - irregulares. RESULTADOS: A ponta diamantada produziu 3 cavidades adequadas, 2regulares e 1 irregular; a ponta lisa, 5 adequadas, 1 regular e nenhuma irregular. A associação de ambaspropiciou 2 cavidades adequadas, 3 regulares e 1 irregular. CONCLUSÃO: Não houve diferença estatísticana qualidade das cavidades preparadas com pontas lisas, diamantadas ou na associação das duas. Quanto àavaliação realizada com os microscópios clínico e o de varredura, não houve diferença estatística entre eles.

OBJECTIVE: To evaluate the quality of root-end preparations using ultrasonic stainless steel and diamond coated tips used individually or associated. The cavity walls were analyzed using a clinical microscope and by scanning electron microscopy (SEM). MATERIAL AND METHOD: Eighteen single rooted mandibular premolars weresubmitted to apicectomy and root-end cavities were performed using ultrasonic tips. The teeth were divided according to the ultrasonic tip used. Group 1 (n=6) stainless steel tips. Group 2 (n=6) diamond coated tips. Group 3 (n=6) the cavity was done initially with a diamond coated tip and finished using a non-coated tip. Three scores were assigned to evaluate the quality of the cavity walls: 1 adequate; 2 regular; 3 inadequate. RESULTS: Diamond coated tip preparation showed 3 adequate cavities, 2 regulars and 1 inadequate. The stainless steel tip preparation showed 5 adequate cavities and 1 regular. The association of the tips showed 2 adequate cavities, 3 regulars and 1 inadequate. CONCLUSION: There was no statistically difference in the quality preparation for the analyzed groups. There was no statistically difference in the evaluation using a clinical microscope or SEM.

Peri Apical Endodontic Surgery - Two Year Follow Up: A Case Report.

The endodontic treatment of necrotic anterior teeth after trauma remains complicated because of divergent root walls, thin dentinal walls and frequent lesions. The surgical endodontic treatment of teeth are well documented which are characterized by necrosis and infection in the presence of older fibrous and extensive lesion. The purpose of this paper is to report a two year follow up of a twelve years old patient whose tooth was treated for periapical lesion of endodontic origin by surgical endodontic procedure.
