Mandibular molar with five root canals

The purpose of this study was to demonstrate the importance of knowledge of the internal anatomy of root canals for the success of endodontic treatment. Lack of knowledge of anatomic variations and their characteristics in different teeth has been pointed out as one of the main causes of endodontic therapy failure. In this report, the authors describe the endodontic treatment of a mandibular first molar with five root canals, evaluate the rate of occurrence of this number of canals, and discuss the importance of their identification and treatment.

Anatomical Aspects of Permanent Geminate Superior Central Incisives

La geminacion dental es una alteracion morfologica que puede suceder durante el desarrollo dental del embrion, dando por resultado la formacion parcial o total de dos dientes que no esten separados totalmente. El objetivo de este trabajo fue describir un caso infrecuente de geminacion, a traves de la radiografia periapical en incisivos centrales superiores en la denticion permanente.

In vitro evaluation of the presence of apical deviation with employment of automated handpieces with continuous and alternate motion for root canal preparation

The present study conducted an in vitro evaluation of the presence of apical deviation on the root canal preparation of the mesiobuccal roots of human maxillary molars employing automated handpieces with continuous motion, the Pow R system (Moyco Union Broach), and alternate motion, the M4 system (Kerr). Analysis of the presence of apical deviation was carried out by means of radiographs obtained on a radiographic desk fabricated for the study. The results demonstrated the lack of statistically significant differences between the two systems as to the evaluation of the presence of apical deviation. There was no correlation between the degree of curvature of the roots and the degree of apical deviation for the continuous motion system. However, there was a statistic difference for the alternate motion system, with a direct correlation of moderate degree.

Study of Prevalence of Internal Resorption in Periapical Radiography of Anteriors Permanents Tooth

El objetivo del estudio fue evaluar, a traves de fichas clinicas y radiologicas, la prevalencia nacional de reabsorcion interna en los dientes anteriores permanentes de los pacientes con atencion en la Clinica del Diplomado de Endodoncia de la Universidad Federal de Pernambuco, en el periodo entre septiembre de 2001 y junio de 2007. Se analizaron 888 prontuarios de los archivos de la Clinica. De ellos, 232 estaban relacionadas con los dientes anteriores. Se observo radiograficamente la presencia de reabsorcion y su ubicacion. Los resultados mostraron que la reabsorcion interna fue prevalente en 2,16% de los casos, de los cuales en 0,86% estaba ubicada en la region coronaria, 0,44% en la raiz y 0,86% en ambas regiones. Se concluye que aun en caso de una enfermedad con baja incidencia, es importante para el especialista conocerla, haciendo un buen diagnostico y una planificacion para el tratamiento adecuado a la situacion, ya que la de negligencia ante un caso de reabsorcion interna en dientes permanentes anteriores, conduce a la perdida del elemento dental, causando cambios funcionales y esteticos para el paciente.

Avaliação dos critérios utilizados na análise dos tratamentos endodônticos realizados por especialistas da cidade do Recife (PE)

This study aimed to evaluate the criteria used by endodontic specialists registered at CRO-PE, during follow-up procedures in endodontics treatments. The data were collected using a form applied to 38 professionals, performed by a single researcher. Among specia- lists who had an evaluation system, the majority used the telephone for contact and they also answered that a mean of33.54% of the patients return for evaluation. When questioned about clinical examination procedures, all of them mentioned they ask about some symptomatology and take radiographs. From those, 41,9% mentioned that locator cone is always used and 64,5% informed that, occasionally, use more than one radiographic exposure. In follow-ups which did not show success, conventional endodontic treatment was the most frequent management mentioned (93,5%). To evaluate treatment outcome, radiographs showing normal structures and no symptomatic tooth was the most frequent item, 93,5%and 90,3%, respectively. For 40%ofthe dentists, the ideal time to evaluate treatment success was 02 years. ln vital pulp, 54,8% mentioned that the period was of 06 months. In dead pulp without periapicallesion, the period was of 01 year (48,4%);for dead pulp with periapicallesion, the period was of 02 years (48,4%). It might be concluded that although the follow-uprepresents a very impor- tant procedure, it is not mentioned by the totality of the specialists, however, aspects as the sympto- matology and the use of radio- graphs are criteria always mentio- ned by those who had this system.
