En los últimos años se ha medido en el ámbito clínico a un número significativo de personas atractivas para desarrollar una guía estética y científica que ayude a la evaluación facial. Estos estudios nos brindan los cánones faciales de estética pero, lamentablemente, estos cánones no se pueden aplicar completamente en nuestro medio porque se desarrollaron para europeoides, caucásicos, americanos de ascendencia europea además de afroamericanos, mongoles y árabes. Considerando, que un etíope es diferente de un mongol, se pudieron realizar múltiples comparaciones. Por este motivo, se analizó dos parámetros de la sonrisa en nuestra población de carácter multiétnico que, con el paso del tiempo y con la posible base genética (evolución), manifiesta un patrón de proporción diferente, de alguna manera, a los establecidos en otras latitudes. El objetivo de este estudio fue determinar si existe relación en la morfología dental y cenit gingival de las piezas dentales antero superiores en adolescentes peruanos. La muestra seleccionada, fueron modelos de estudio de 92 adolescentes de 12-17 años de edad, 46 femenino y 46 masculino, que no presenten gingivitis moderada o severa, algún tipo de restauración anterior, recesión gingival, ausencia de alguna pieza dentaria antero superior, que no hayan tenido o presenten tratamiento de ortodoncia y piezas dentarias ubicadas correctamente dentro del arco dentario. Se registró de ellos el tipo de morfología dental, cenit gingival y distancia del cenit gingival al eje longitudinal de la pieza dentaria. El promedio del cenit gingival fue para el IC, 72,8% a distal con un valor de 0,54 mm, y para el IL y canino 59,2% y 50,5% respectivamente, sobre el eje longitudinal de la pieza dentaria. El tipo de morfología fue oval con un 71,2 %, 67,9% y 73,9% en IC, IL y C, respectivamente. Solo se halló relación en los incisivos centrales y caninos con morfología oval cuyo cenit se ubica a distal y sobre el eje longitudinal, respectivamente. Los hallazgos del presente estudio pueden ser utilizados en conjunto con otros objetivos y parámetros subjetivos para ayudar al odontólogo en el manejo interdisciplinario de la estética anterior, como un gran aporte durante la planificación del tratamiento, del diseño de sonrisa, procedimiento de alargamiento de corona, durante la colocación de una corona, la selección de los dientes, la estética de implantes y cirugía periodontal. / --- In recent years it has been measured in the clinical setting to a significant number of attractive to develop an aesthetic and scientific guide to help people facial evaluation. These studies provide us with facial aesthetic canons but unfortunately, these fees can not be fully applied in our country because it developed to europeoides, Caucasians, Americans of European descent plus African Americans, Mongols and Arabs. Whereas, an Ethiopian is different from a Mongolian, they could be performed multiple comparisons. For this reason, two parameters was analyzed smile in our multiethnic population, with the passage of time and the possible genetic basis (evolution), shows a different pattern of proportion, somehow, to those established in other latitudes. The aim of this study was to determine whether there is a relationship in dental morphology and gingival zenith of the upper anterior teeth in Peruvian adolescents. The sample were 92 study models of adolescents aged 12-17 years, 46 female and 46 male, showing no moderate or severe gingivitis, any previous restoration, gingival recession, absence of a superior and anterior tooth you had orthodontic treatment or present, teeth properly located within the dental arch. The type of dental morphology, gingival zenith and gingival zenith distance from the longitudinal axis of the tooth was recorded from them. The average peak was for gingival IC, 72.8% to distal with a value of 0.54 mm, and for canine IL and 59.2% and 50.5% respectively, on the longitudinal axis of the tooth. Type morphology was oval with 71.2%, 67.9% and 73.9% in IC, IL and C, respectively. Relationship was found only in the central incisors with oval morphology which is located distal zenith. The findings of this study can be used in conjunction with other objective and subjective parameters to assist the dentist in the multidisciplinary management of anterior aesthetics, as a great contribution during treatment planning, the design of smile, crown lengthening procedure, during placement of a crown, the selection of the teeth, periodontal implants and aesthetic surgery.

Background and Objective: Smoking is one of the major risk factors for chronic periodontitis. However, the mechanisms involved in tissue degradation due to cigarette smoking are not clear. Receptor activator of nuclear factor kappa B ligand (RANKL) and osteoprotegerin (OPG) are a system of molecules that regulate bone resorption. The aim of this study was to compare the levels of soluble RANKL (sRANKL), OPG and their relative ratio in GCF among periodontitis patients with varying smoking histories. Material and Methods: GCF samples were collected from 149 periodontitis patients who were never smokers (n=58), former smokers (n=39) and current smokers (n=52). sRANKL and OPG concentrations in GCF were measured by enzyme-linked immunosorbent assays. Results: sRANKL, OPG and their relative ratio were not statistically significant among the never smokers, former smokers and current smokers. However, OPG was significantly reduced and subsequently the sRANKL:OPG ratio was significantly increased in the high pack-years group as compared with never smokers. The positive correlation between packyears and sRANKL:OPG ratio was statistically significant even after adjusting for age and current smoking status. Conclusion: Increased lifetime exposure to cigarette smoking above a minimum threshold suppresses OPG production and leads to increased sRANKL:OPG. This may partially explain increased bone loss in smoking-related periodontitis. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1352109 / Thesis (D.Clin.Dent.) - University of Adelaide, School of Dentistry, 2009
