Resumen
El objetivo de este estudio fue caracterizar el perfil de proteínas de la saliva total
en personas edéntulas parcial y total y determinar los cambios en la expresión de proteínas
salivales de adultos con diversos grados de pérdida de dientes. Métodos. En este estudio observacional,
se recogieron muestras de saliva no estimulada de 80 adultos (de 18 a 73 años),
20 dentados y 60 desdentados. Los pacientes edéntulos (PE) parcial y total se dividieron en
tres grupos con diferente número de dientes perdidos. Se compararon la concentración y el
perfil electroforético (membrana de acetato de celulosa y geles de poliacrilamida) de las proteínas
salivales entre los grupos. Resultados. La concentración de proteína total y albúmina
fue más alta en el grupo de pacientes dentados (PD) y significativamente diferente en los
grupos de PE (p<0,0001). Se observó una diferencia significativa (p<0,011) en la fracción
de gammaglobulina entre PD versus PE y en el perfil electroforético de las proteínas salivales
entre los diferentes grupos. Un número elevado de bandas de 66 kDa se encontró en
todos los grupos (p=0,049). Conclusiones. Se observaron diferencias en la concentración
y perfil electroforético de las proteínas salivales de PD y PE.
Aim of this study was to characterize the protein profile of whole saliva in partial and complete edentulous and determine the changes in salivary protein expression of adults with varying degrees of tooth loss. Methods. In this observational study, unstimulated saliva samples were collected from 80 adults (age 18-73 years), 20 dentulous and 60 edentulous. Partial and complete edentulous patients (EP) were divided into three groups with different number of teeth lost. Concentration and electrophoretic profile (cellulose acetate membrane and polyacrylamide gels) of the salivary proteins were compared between the groups. Results. Total protein and albumin concentration was highest in the group of dentulous patients (DP) and significantly different in PE groups (p<0.0001). A significant difference (p<0.011) was observed in the gamma globulin fraction between PD versus PE and in the electrophoretic profile of salivary proteins between the different groups. A high number of 66 kDa bands was founded in all groups (p=0.049). Conclusions. The concentration and electrophoretic profile of the salivary proteins of DP and EP were different.
