Burning mouth syndrome (BMS) is a chronic intraoral pain state that has been described as burning pain, tingling or numbness in the oral mucosa, in the absence of any organic disease. Most often affecting the tongue, anterior palate, and/or lips. The diagnosis of primary BMS is purely clinical and based on patients’ description of typical subjective symptoms as well on the exclusion of any systemic or local factors that may give rise to secondary burning pain sensations within the oral mucosa. Relevant studies links BMS to a peripheral neuropathy and BMS patients have revealed distinct abnormalities within the trigeminofacial large and small fiber systems and the trigeminal brainstem complex. Therefore, treatment approach should involve a multidisciplinary character similar to the treatment for neuropathic pain including factors that might also play a role on the BMS etiology and pathophysiology.

The objective of this article was to analyze the indications for the proper selection of  Onlay adhesive ceramic restorations, providing a step-by-step clinical protocol. Biomechanical principles based on morphological considerations and geometric terms must be present for the careful preparation of Onlay-type cavities. Concepts about cavitary preparations are discussed under essential conditions in the preservation of healthy dental tissue, without compromising the functional and aesthetic results over time. The author's suggestion is to respect and follow in a timely manner each of the steps applied in this restorative clinical protocol, to improve the final outcome of the restoration.

Maxillary sinus floor elevation has been extensively documented as a safe and predictable procedure for gaining vertical bone height in the atrophic posterior maxilla. Even though, complications have been reported, which can potentially jeopardize the outcome of the regeneration and implant therapy. Therefore, the purpose of this literature review is to present, debate and analyze the different complications that can occur during a sinus floor elevation.

Objective: Determine sexual dimorphism precision via palatal vault morphometric analysis in craniums sourced from the Laboratorio de Investigación Forense del Equipo Forense Especializado (EFE) de Ayacucho del Ministerio Público - Perú. Materials and Methods: Cross-sectional design consisting of a sample of 43 skulls with pre-established biological gender, (24 males and 19 females). Sexual dimorphism was established by means of the method proposed by Meera Jacob and co., based on palatal width and length measurements, after which the palatal index was calculated, establishing the method’s precision and accuracy. The inferential analysis was made with a level of significance of 5% through the T student test, Shapiro Wilk and Pearson’s coefficient. Results: Palatal width had a mean of 3.43 (+0.31cm) for males and 3.62 (+0.25) for females and in palatal length a mean of 5.07 (+0.44) cm. for males and 4.79 (+0.41) cm. for females is established; on palatal index, 100% of the male skulls correspond to hard narrow palate and on females 73.7% to narrow, 21% to intermediate and 5.3% to wide. Furthermore, it was determined that there were statistically significant differences between width and length of palatal vault for both genders, and a discriminating analysis formula was proposed. Conclusion: Morphometric analyses of palatal vaults establish an 83.72% precision on the estimation of sexual dimorphism.

Amaranth, due to its nutritional composition (carbohydrates 50-66%, lipids 1.9-9.7% and proteins 12-22%) has been selected by FAO as the best food of vegetable origin, it has also been reported that amaranth exerts beneficial effects on health such as lowering the blood cholesterol level, stimulating the immune system, having antioxidant activity as well as protecting against cancer. In some researches, it has been mentioned that thermal pre-treatments such as roasting, extrusion and explosion, applied to amaranth grain before flour processing, have an impact on nutrient content and bioavailability of nutrients. The high content of proteins makes amaranth an attractive substrate for the growth of probiotic lactic acid bacteria, which would complement the benefits provided by the nutrients of amaranth and would be an alternative of probiotic consumption for those people who cannot consume them regularly (lactose intolerant, allergic to milk protein, gluten or soy). Therefore, the objective of this research was to evaluate the effect of pretreatments on the functionality of amaranth seed extracts as a substrate for the growth of probiotic lactic acid bacteria. To achieve this goal, extracts of amaranth flour were prepared from: without treatment, washed, cooked and burst seeds. The protein content, reducing sugars and total carbohydrates were determined to the extracts. Growth kinetics of Lactobacillus plantarum were developed by the pouring plate method. The results show that amaranth extracts are functional for the culture of L. plantarum and that only the explosion of the seeds seems to affect the availability of nutrients since it was in the only extract where a significantly lower maximum cell growth was observed (1.44 ± 0.04 Log UFC/UFC0), Nevertheless the rate of growth was not affected.

The effect of different levels of maralfalfa meal (Pennisetum purpureum) (5, 10, 15 and 20%), in the diet of New Zealand rabbits (Oryctolagus cuniculus) from weaning to the beginning of the reproductive life, was evaluated. 4 treatments with 5 repetitions to be compared with a control treatment. A completely randomized design was applied in combinatorial arrangement of two factors, where the, factor A, were the levels of maralfalfa flour and the B factor, the sex of the animal. The results of the present investigation show that the use of maralfalfa flour supplied to rabbits improves the productive parameters, which is reflected in a reduction of costs and an increase in profitability, observing that when applying 20% of maralfalfa flour, better final weight (4.51kg), higher weight gain (3.63kg) with a total feed intake of 3.63 kg / MS (Dry matter) were recorded; feed conversion (4.20); weight to the carcass (2.61kg) and yield to the carcass (58.53%).

Chlorhexidine and fluor are treatment which have been used to prevent dental plaque formation and, subsequently, dental cavities. The objective of this study was to identify the effectivity of chlorhexidine in varnish to prevent dental plaque formation. A quantitative test was carried out, comparative-descriptive, transversal and observational. The sample observed was integrated by 13 children from 6 to 10 years old, to whom, a questionnaire about fermentable carbohydrates consumption was applied; they were identified to have dental plaque, registering it through the O’Leary index. Later, they were divided into two groups, the first group was applied fluor varnish at 0.1%, and the second group was applied chlorhexidine varnish at 1% with Thymol at 1% as a homogenous mixture. Four weeks later, second dental plaque identification was executed and registered in the same initial way. The data was analyzed stablishing an average, standard deviation and Pearson correlation coefficient. The results obtained indicate that there is a weak negative correlation (-0.13) between the O’Leary index and fermentable carbohydrates consumption, a weak negative correlation (-0.065) when correlating the O’Leary index obtained after fluor application and fermentable carbohydrate consumption; as well as a weak positive correlation (0.084) when correlating the O’Leary index obtained after chlorhexidine application and fermentable carbohydrate consumption. It is concluded that, in order to determine the effectiveness of this drug, it is necessary to augment the sample size, and deeper studies must be done having into consideration other factors not analyzed in this investigation since, apparently, chlorhexidine usage is not enough to impact positively on the presence of dental plaque and caries.

As part of the communicative processes that transform and establish the social dynamics, the confidence forms a part fundamentally of the foundations that determine attitudes towards institutions, groups or organizations.This article aims to analize the confidence shown by fans of the Olmec baseball team in Tabasco, which determines the relationship and behavior that exists among baseball fans in relation to the results obtained in the last season through an analysis using the theory of social representations as a basic premise for their development. To establish confidence index, the oficial page of the team was tracked and a five-items questionnaire was built between 100 attendees at the last of the games, revealing that the team´s follow-up is generated primarily by aspects of identity, with a lesser influence of the opinions expressed in the media and based on previous results, where this team has not achieved triumphs for 25 years.

The present document analyses the mexican identity in furniture design. In this explorative investigation the authors did a referential framework of Mexican identity in furniture design, using a semiotic point of view. The main purpose of this research is to distinguish the features of the Mexican culture and to analyze their application as identity in furniture design in Mexico. The image of the mexican furniture presents reminiscences in the decorative part and volumes derived from the Spanish furniture that are identified through the semiotics of the furniture image.

El turismo sostenible se sustenta en una serie de criterios que modelan la forma de hacer turismo, para ello la OMT ha establecido 12 objetivos vinculados a los pilares de la sostenibilidad. Se propone además que el turismo sostenible se sustenta en una visión holística que permite y promueve la calidad de vida tanto de los que la ofrecen, como de quienes le visitan. Este modo de turismo requiere de compromiso y acciones multisectoriales, se hace mención a la experiencia de Costa Rica y se reconocen algunos factores diferenciadores incluyendo la importancia que tiene reconocer que por más pequeño que sea su aporte, como país o persona, no debemos escatimar esfuerzos para avanzar en la sostenibilidad. Finalmente se recuerda el valor que tienen los productos competitivos y sus requerimientos en las ofertas de los destinos, cuando estos buscan consolidarse o trabajan sobre su estado de madurez, tal es el caso de Costa Rica.
