Patrón de masticación en las clases III de angle / Masticatory pattern in Angle class III patients

Se seleccionó una muestra de 12 pacientes (cuatro hombres y ocho mujeres) con edad promedio de 17.6 años, los cuales tenían diagnóstico de clase III de Angle y mordida cruzada posterior.- Los resultados mostraron que el 75 por ciento de los pacientes desplazaban la mandíbula hacia el lado de trabajo. El 66 por ciento de la muestra en masticación izquierda y el 75 por ciento en masticación derecha tenían desplazamiento condilar hacia el lado de no trabajo. No se encontró relación entre el desplazamiento del cóndilo con la situación de la mordida cruzada ni con la severidad de la misma...

Passive wedge.

The article describes a new technique for fabricating a wedge directly in the mouth during clinical procedures. It is called a passive wedge because it is kind to the soft tissues, exerting neither compression nor traction on them. A conventional rigid wedge may hurt the interdental papilla, initiating bleeding and the flow of fluids through the rubber dam. This new technique is very useful during adhesive procedures, because the wedge prevents moisture from invading the working area and the cavity, maintains the matrix in place, and causes no harm to the soft tissues, allowing the restoration to be finished properly.

DMFT and treatment needs in adult population of Oviedo, Spain.

An epidemiological survey was carried out in 1992 researching dental caries and treatment needs in an adult population in Oviedo, Spain. A representative sample of 261 subjects, randomly obtained and stratified by age, was examined. Results show a dental decay prevalence of 99.6%; 12.5 DMFT index with 2.9, 7.5 and 2.1 mean values for D, M and F components. Women and the lower social class showed the highest DMFT index. Treatment needs reach a mean value of 12.1 teeth per person. Pontics are the most needed treatment, the mean value increases with age while the differences among age groups and social classes are statistically significant. The next most needed dental treatment is filling of one surface which decreases with age, is the same for men and women and higher among the middle social class; the differences are statistically significant among the social classes.

Determination of the horizontal movement of the working-side condyle during lateral movements of the mandible using computed tomography.

The purpose of this study was to evaluate the horizontal movement of the working-side condyle during lateral movements of the mandible using computed tomography. The results showed that the working-side condyle moves in an outward and forward direction from the position of maximum intercuspation. The average movement is less than 1 mm.

[Post-radiotherapy xerostomia in patients with oral cancer. Changes in salivary inorganic components and immunoglobulins]. / Xerostomía post-radioterapia en pacientes con cáncer oral. Modificaciones de los componentes inorgánicos e inmunoglobulinas de la saliva.

Following therapeutic doses of irradiation to the salivary glands the glandular tissues suffer an early degeneration of the serous cells and focal necrosis of the parenchyma. Xerostomia is present and persist for a time, depending upon the dose of irradiation.

Simplified method of odontograms for individual identification.

A computerized method of codifying dental lesions and treatment is presented to enable faster identification of victims of catastrophes. Each tooth is assigned a bidigital value. The first digit refers to the root and designates whether it is found to be perfect, damaged and/or treated, or absent. The second digit refers to the crown and is assigned according to the number of surfaces showing lesions or treatment. For the identification of corpses, missing individuals whose record reveals values less than or equal to those of the subject in every tooth (or of each quadrant in cases of doubt) are selected for consideration from the data base. Individuals who have even one tooth with a value greater than that of the subject are eliminated.

[Evaluation of endodontic treatment with modified Walkhoff technique in teeth with necrotic pulp and/or periapical lesions]. / Evaluación del tratamiento endodóntico con la técnica de Walkhoff modificada, en dientes con pulpa necrótica y/o lesiones periapicales.

A treatment has been carried out in a total of 112 dental cases with necrotic pulp and/or periapical lesions using yodoformic paste. The technique employed was that of a conventional endodontic therapy of the root and ductal filling, using yodoformic paste and gutta-percha. The clinical and radiological follow up checks, three, six and twelve months after treatment, show improvement in the periapical lesions, with bone regrowth and complete disappearance of the radio-lucity within a variable time span, depending on the gravity of the damage, but never greater than twelve months. The immediate post-operative well being and absence of complications in the majority of cases also be highlighted.
