Analysis of the esthetic preferences of Spanish laypersons and dentists regarding the different width proportions of the maxillary anterior teeth.

STATEMENT OF PROBLEM: Multiple esthetic width proportions have been described for maxillary anterior teeth. However, the esthetic characteristics of each have not been compared simultaneously to determine which proportion is preferred by dentists and laypersons. PURPOSE: The purpose of this study was to evaluate the preferences of dentists and laypersons with respect to internationally recognized dental esthetic proportions. It also sought to determine whether a relationship existed among dentists' preferences as per their specialty and among laypersons as per their academic field. MATERIAL AND METHODS: Two smile images, one male and one female, were digitally modified to meet the golden proportion and the recurring esthetic dental (70%) and golden percentage. The 2 resulting sets of images (original images and digitally altered ones) were presented to dentists and laypersons through a Web-based survey site. The Pearson chi-squared and Fisher tests were used to assess the differences in the esthetic preferences among the groups (α=.05). RESULTS: A total of 363 answers were obtained from dentists and 750 from laypersons. Both groups considered recurring esthetic dental to be the most esthetic proportion and golden proportion to be the least esthetic proportion. The dentists' preferences as per their specialty followed the same trend, whereas the laypersons' preferences were more scattered according to their academic field. The recurring esthetic dental proportion was preferred in images of both sexes, golden proportion smiles were the least preferred for female smiles, and golden percentage was the least preferred for male smiles. CONCLUSIONS: The results obtained indicated that the preferred esthetic proportion both for dentists and laypersons was the recurring esthetic dental 70%, with the dentists' specialty or laypersons branch of knowledge not affecting choice.

Análisis bibliométrico de la producción científica de la Revista Española de Cirugía Oral y Maxilofacial durante el periodo 2005-2011 / Bibliometric analysis of the scientific production of the Revista Española de Cirugía Oral y Maxilofacial during the period 2005-2011

Objetivos. El presente trabajo tiene como objetivo principal analizar cuantitativamente la producción científica recogida en la Revista Española de Cirugía Oral y Maxilofacial (RECOM) durante los años 2005-2011, procediendo a un estudio bibliométrico de la misma. Material y método. Se ha realizado un estudio descriptivo longitudinal sobre los artículos publicados en la revista RECOM entre enero de 2005 y diciembre de 2011. Las variables investigadas fueron: tipologías documentales de carácter científico, temática e idioma de publicación, procedencia geográfica, filiación institucional e índice de cooperación, tiempo medio entre la recepción del trabajo y su aceptación y número de veces que se citan trabajos publicados en la propia RECOM. Resultados. En el periodo examinado se publicaron en la RECOM un total de 200 artículos científicos, principalmente casos clínicos sobre cirugía oral u oncología escritos en español. Los hospitales de Madrid atesoran el 28% de la producción de artículos en la revista y el número de trabajos internacionales es bajo (el 23% de procedencia iberomericana y solo el 2% de origen europeo). El tiempo medio de espera entre el envío de la documentación y su aceptación es de 269 días. El índice de referencias recibidas por artículos publicados en la propia RECOM ha sido de un 4%. Conclusión. En el periodo de tiempo examinado la RECOM ha experimentado importantes mejoras, que sin embargo deberá continuar implementando para ganar reconocimiento (AU)

Objectives. The aim of this work is to perform a quantitative analysis of the scientific production appearing in the Revista Española de Cirugía Oral y Maxilofacial (RECOM) between the years 2005 and 2011, followed by a literature review of these contents. Material and method. A descriptive and longitudinal study was conducted on the articles published in the RECOM Journal between January 2005 and December 2011. The investigated variables were: documental types with scientific character, topics, and language in which it was published, source, institutional affiliations and multiple authorship, mean time between the submission of the paper, and the number of times that articles have been mentioned by RECOM itself. Results. A total of 200 scientific articles were published in RECOM during the period studied, mostly clinical cases about oral surgery or oncology written in Spanish. Madrid hospitals produced 28% of the articles in this journal, and the number of international papers was low (23% from South America, and only 2% European). The mean waiting time between submitting the documentation and its acceptance was 296 days. The reference index received for articles published in the RECOM was 4%. Conclusion. There was significant in RECOM during the period studied, improvements that must continue in order to gain recognition (AU)

Clinical outcomes after the use of complete autologous oral mucosa equivalents: preliminary cases.

OBJECTIVE: Previously, we reported how to obtain complete autologous oral mucosa equivalents (CAOMEs) composed of an autologous plasma scaffold and fibroblasts together with immature keratinocytes able to build an oral epithelium with a structure similar to that of the oral mucosa. In this study, we present the clinical outcomes after applying our CAOMEs as grafts. STUDY DESIGN: Four patients who needed a CAOME to restore a defect of oral mucosa were selected. Two of the patients suffered from ankyloglossia, and the other 2 required a restoration of the keratinized gum of the alveolar rim. To assess the outcomes, the scale designed by Ewers et al. was used. RESULTS: Clinical and functional improvements were achieved in the patients with ankyloglossia. In cases of gum restoration, the mucosa was regenerated and a prosthetic restoration with implants was achieved. CONCLUSIONS: The results obtained points to the potential use of CAOME in intraoral lining.

Use of autologous skin equivalents with artificial dermal matrix (integra) in donor site coverage in radial forearm free flaps: preliminary cases.

PURPOSE: The radial forearm flap is one of the most commonly used methods for intraoral reconstruction in oral carcinoma surgery. One of its disadvantages is the residual functional and unaesthetic defect in the donor site. The objective of this report is to describe preliminary cases of a novel method to cover such donor sites based on the use of autologous skin equivalents (ASEs) and an artificial dermal matrix (Integra, Prim, Barcelona, Spain). MATERIALS AND METHODS: The donor sites of 2 patients were treated with the artificial dermal matrix after raising a radial forearm flap. A skin biopsy and a blood sample were taken to construct an ASE. After 3 weeks, the ASE was applied over the dermal template and left to heal. The functional and esthetic results were recorded. RESULTS: Good functional and esthetic results were achieved, with correct wrist motility, although a natural skin color could not be achieved. Neither the Integra nor the ASE was rejected. Total wound coverage was achieved at 4 months, and completely normal skin was observed at 6 months. CONCLUSIONS: This technique of combining an artificial dermal matrix with an ASE could be an alternative method to cover the donor sites of radial forearm flaps.

Expression of Bcl-2 but not Bax has a prognostic significance in tongue carcinoma.

BACKGROUND: Among the molecular mechanisms involved in carcinogenesis, defects in the regulation of programmed cell death (apoptosis) make important contributions to the pathogenesis and progression of cancer. Apoptosis regulatory genes include the antiapoptotic bcl-2 gene and the proapoptotic bax gene. The aim of this study was to determine the spectrum of Bax and Bcl-2 expression, and to correlate these findings with clinicopathologic variables and prognosis. METHODS: In this study we have evaluated the immunohistochemical expression of Bcl-2 and Bax proteins in a series of 35 squamous cell carcinomas of the tongue. RESULTS: Immunoreactivity for Bax was detected in 37.1% and for Bcl-2 in 8.6% of cells, and for both proteins the staining was cytoplasmic and granular. Bcl-2 and Bax expression was mainly seen in peripheral cells of epithelial tumor islands with decreasing immunoreactivity toward the center of the neoplastic nests. Bax immunoexpression was significantly correlated with histologic grading (P=0.05), but not with the remaining clinicopathologic variables. Bcl-2 immunoreactivity was significantly correlated with N-stage (P=0.01) and survival. Patients with Bcl-2-negative tumors [mean survival: 73.97 months; 95% confidence interval (CI): 59-88] vs. Bcl-2-positive ones (mean survival: 17.67 months; 95% CI: 6-29) had a longer survival (P=0.01; odds ratio=6.9). CONCLUSIONS: Bcl-2 is associated with aggressive disease, neck lymph node metastasis, and poor prognosis. Whereas Bax is related with histologic grade.
