Tratamiento endodóntico de un diente invaginado con conservación de la vitalidad pulpar. Caso clínico y revisión de la literatura / Endodontic treatment of invaginated tooth with presevation of pulp vitality. Case report and review of literature

Uno de los retos más difíciles que tiene el clínico ante la necesidad de un tratamiento de conductos de un diente invaginado es la variabilidad y complejidad anatómica que presenta el sistema de conductos radiculares. En algunas situaciones, el tratamiento endodóntico exclusivo de la zona invaginada puede conllevar a la reparación de la lesión periapical y a la conservación de la vitalidad pulpar del diente (AU)

One of the most difficult challenges for the clinician who has to perform a root canal treatment of invaginated teth is the anatomic variability and complexity presented by the canal system. In some situations, endodontic treatment unique to invaginated area can lead to periapical lesion repair and conservation of tooth pulp vitality (AU)

Estudio comparativo in vitro del diagnóstico de las caries de fosas, surcos y fisuras de dientes del sector posterior, por examen visual y un sistema de fluorescencia producida por láser / Comparative study in vitro in the diagnostic of fissure caries. groores and teeth fissures in the posterior area by visual examination and a lase fluorescence system

Se estudian in vitro 63 dientes del sector posterior, sin caries aparente o con caries no cavitadas de fosas, surcos fisuras, por examen visual y un Sistema de Fluorescencia producida por Láser. Se confirma la falta de fiabilidad de los criterios clínicos para la detección de caries en estas localizaciones y se proponen valores que se correlacionan con el grado de profundidad de las lesiones. Se concluye que la exploración clínica sola no es suficiente para detectar caries de fosas, surcos y fisuras, pero que el Sistema de Fluorescencia producida por Láser puede ser una técnica de exploración adecuada para establecer el grado de profundidad de estas lesiones (AU)

[Diabetes as a risk factor for tooth loss in the geriatric population]. / La diabetes como factor de riesgo de edentación en la población geriátrica.

OBJECTIVE: A comparative study of the level and type of tooth loss, and the use of dental prostheses, was performed on one diabetic sample and another non-diabetic one, taken from elderly people receiving health care at the San Pablo Health Centre, Sevilla, in order to assess the repercussion of diabetes on tooth loss. DESIGN: A descriptive and observational study of a crossover type. SETTING: Primary care. San Pablo Health Centre, Sevilla. PATIENTS AND OTHER PARTICIPANTS: Patients aged > 65 requesting health care for any reason at our PC clinic during March-April 1995. MEASUREMENTS AND MAIN RESULTS: 98 patients, 42 diabetics and 56 non-diabetics, were studied. The percentage of toothlessness was significantly greater in diabetic patients than in non-diabetic ones. None of the patients had kept all their teeth. 52.4% of the diabetic patients wore complete prostheses, percentage which went down to 25% in non-diabetics. 57.1% of diabetics and 44.6% of non-diabetics wore some type of prosthesis. CONCLUSIONS: We can consider diabetes as a risk factor in tooth loss among the elderly. Applying buco-dental hygiene measures from the diagnosis of diabetes, along with regular dental check-ups, might significantly lessen diabetics' dental loss over their lives. Opening the elderly person's mouth, whether he/she is diabetic or not, and evaluating oral mucus and dental structure, should be a investigative procedure in primary care.

[Dentin desensitization with 2% sodium fluoride during cavity preparation]. / Desensibilizazión dentinaria con fluoruro sódico al 2% durante la preparación cavitaria.

During the preparation of the dental cavity very often the patient notices sensibility to the pain, being unable to perform correctly the work. We obviate this inconvenience using 2% Sodium Fluoride.
