RESUMO
Objetivo: La gingivitis espongiótica es una patología benigna poco común y una entidad clínica patológica poco frecuente que los odontólogos pueden observar durante la atención odontológica. Es importante conocer la misma para poder diagnosticarla adecuadamente, describir sus características clínicas y elaborar un plan para su tratamiento. El objetivo de este artículo es presentar un caso clínico de esta patología poco conocida, describir sus características y su manejo clínico. Caso clínico: Un niño de 7 años que ingresó derivado por su odontólogo a la cátedra de Estomatología de la Facultad de Odontología de la Universidad Nacional de Córdoba, Argentina, presentaba en la encía libre e insertada del maxilar superior una lesión con ausencia de sintomatología y evolución crónica, benigna y con cambios estéticos notorios. Se deriva a la cátedra de Periodoncia para realizar un tratamiento interdisciplinario. Tuvo una respuesta favorable al tratamiento de la lesión, y se realizó un seguimiento periódico de la misma evitando la técnica quirúrgica convencional para su tratamiento.(AU)
Aim: Spongiotic gingivitis is a rare benign pathology and a rare clinical pathological entity that dentists can observe during dental care. It is important to know it to be able to properly diagnose it, describe its clinical characteristics and develop a plan for its treatment. The aim of this article is to present a clinical case of this little-known pathology and describe its characteristics as well as its clinical management. Clinical case: A 7-yeard-old child who was referred by his dentist to the Department of Stomatology of the Faculty of Dentistry of the National University of Córdoba, Argentina, presented a lesion in the free and inserted gingiva of the upper jaw, with absence of symptoms and chronic, benign evolution with notable aesthetic changes. He is referred to the Periodontics department to perform interdisciplinary treatment. He had a favorable response to the treatment of the lesion, and a periodic follow-up was carried out, avoiding the conventional surgical technique for its treatment.(AU)
RESUMO
OBJECTIVE: To determine the frequency of oral squamous cell carcinoma (OSCC) associated or not with oral potentially malignant disorders (OPMD), and the epidemiological profile and traditional risk factors in Latin America. METHODS: A retrospective observational study was conducted in 17 Latin American centres. There were included cases of OSCC, analysing age, gender, OSCC and their association with previous OPMD. Clinicopathological variables were retrieved. The condition of sequential-OSCC versus OSCC-de novo (OSCC-dn) was analysed concerning the aforementioned variables. Quantitative variables were analysed using Student's t-test, and qualitative variables with chi-square. RESULTS: In total, 2705 OSCC were included with a mean age of 62.8 years old. 55.8% were men. 53.75% of the patients were smokers and 38% were common drinkers. The lateral tongue border was the most affected site (24.65%). There were regional variations in OPMD, being leukoplakia the most frequent. Of the overall 2705 OSCC cases, 81.4% corresponded to OSCC-dn, while s-OSCC were 18.6%. Regarding lip vermillion SCC, 35.7% corresponded to de novo lip SCC and 64.3% were associated with previous OPMD. CONCLUSIONS: In Latin America, OSCC-dn seems to be more frequent with regional variations of some clinical and histopathological features. Further prospective studies are needed to analyse this phenomenon.
RESUMO
Introduction: the causative factors of oral squamous cell carcinoma are not necessary and not sufficient causes, even the most accepted ones, such as tobacco and alcohol. Little is known about the cumulative effect of all risk factors for oral cancer. The objective of this work was to analyze whether the sum of oral cancer risk factors is associated with an increase in its risk. Methods: a case-control study was carried out to determine the risk factors for oral cancer in the population under study, and then correlate the number of risk factors in each individual with the risk of oral cancer. Results: the accumulation of oral cancer risk factors, analyzed using different strategies, was always associated with a significant increase in the risk of oral cancer. Having 3 or more risk factors was associated with an increased risk of oral cancer (OR 110, p <0.0001) Conclusion: the main risk factor for oral cancer is the accumulation of its risk factors. The accumulation of risk factors could be considered a necessary cause for the development of oral cancer.
Introducción: los factores causales de carcinoma de células escamosas bucal son causas no necesarias y no suficientes, incluso los más aceptados, como tabaco y alcohol. Poco se conoce sobre el efecto acumulativo de todos los factores de riesgo de cáncer bucal. El objetivo de este trabajo fue analizar si la sumatoria de factores de riesgo de cáncer bucal se asocia con un aumento de su riesgo. Métodos: se realizó un estudio de casos y controles para determinar los factores de riesgo de cáncer bucal en la población bajo estudio, para luego correlacionar el número de factores de riesgo en cada individuo, con el riesgo de cáncer bucal. Resultados: la acumulación de factores de riesgo de cáncer bucal, analizada mediante diferentes estrategias, estuvo siempre asociada con un aumento significativo del riesgo de cáncer bucal. Tener 3 o más factores de riesgo estuvo asociado con mayor riesgo de cáncer bucal (OR 110, p<0,0001) Conclusión: el principal factor de riesgo de cáncer bucal es la acumulación de sus factores de riesgo. La acumulación de factores de riesgo podría considerarse una causa necesaria para el desarrollo de cáncer bucal.

El consumo excesivo de bebidas alcohólicas constituye un serio problema sanitario y social. En los últimos años se han destacado sus propiedades anticancerosas, antioxidantes y protectoras contra la enfermedad cardíaca coronaria, lo que ha generado controversias entre beneficios y perjuicios de su consumo. Los efectos tóxicos sobre el sistema nervioso central lideran el cuadro de la intoxicación aguda, mientras que los efectos del consumo crónico afectan prácticamente todo el organismo, alterando numerosas funciones aún en etapas tempranas de la vida. Los profesionales de las ciencias de la salud tienen un rol clave en la prevención de los daños producidos por este hábito tan difundido.

To analyze the effect of two mouthwashes on salivary pH and correlate it with age, buffer capacity and saliva flow rate in healthy volunteers, a crossover phase IV clinical study involving three age-based groups was designed. Two commercial mouthwashes (MW), Cool Mint ListerineR (MWa) and Periobacter R (MWb) were used. The unstimulated saliva of each individual was first characterized by measuring flow rate, pH, and buffer capacity. Salivary pH was evaluated before rinsing with a given MW, immediately after rinsing, 5 minutes later, and then every 10 min (at 15, 25, 35 min) until the baseline pH was recovered. Paired t-test, ANOVA with a randomized block design, and Pearson correlation tests were used. Averages were 0.63 mL/min, 7.06, and 0.87 for flow rate, pH, and buffer capacity, respectively. An immediate significant increase in salivary pH was observed after rinsing, reaching average values of 7.24 (MWb) and 7.30 (MWa), which declined to an almost stable value 15 minutes. The great increase in salivary pH, after MW use shows that saliva is a dynamic system, and that the organism is capable of responding to a stimulus with changes in its composition. It is thus evident that pH of the external agent alone is not a good indicator for its erosive potential because biological systems tend to neutralize it. The results of this study enhance the importance of in vivo measurements and reinforce the concept of the protective action of saliva.

Etários de adultos voluntarios sanos, para analizar el efecto de dos colutorios sobre el pH salival y relacionarlo con la edad la capacidad buffer y el flujo salival. Se utilizaron dos marcascomerciales de colutorios (MW), ListerineCoolMint® (MWa) y eriobacter® (MWb). Primero se caracterizó la saliva sin estimular de cada individuo, se le midió el volumen minuto, el pH y la capacidad buffer. El pH salival se evaluó antes del buche con cada MW, inmediatamente después del enjuague bucal, 5 minutos después y luego cada 10 minutos (a los 15,25, 35 min) hasta que el pH inicial se recuperó. Para el análisis estadístico de los datos se utilizaron: ANOVA en bloque,test t apareado y el test de correlación de Pearson. Al caracterizar la saliva, se obtuvieron los siguientes valores promedio: 0.63 mL/min, 7.06 y 0.87 de volumen minuto,pH, y capacidadbuffer. Luego del enjuague se observó un incremento inmediato y significativo del pH salival alcanzando valores de 7.24 (MWb) y 7.30 (MWa) para descender a un valor estable luegode 15 minutos. El importante incremento del pH salival luego del uso del colutorio, muestra que la saliva es un sistema dinámico y que el organismo es capaz de responder a estímulos con cambios en su composición. Se hace evidente que el pH del agente externo, no es un buen indicador de su potencialerosivo sobre los elementos dentarios ya que los sistemas biológicos tienden a neutralizarlo. Los presentes resultadosponen de manifiesto la importancia de las mediciones en vivo y refuerzan el concepto de la función protectora de la saliva...
