Dairy Products! Way To Periodontal Health







The recent article in Jol Of Peridontology reports the beneficial effects of dairy products on periodontal disease. Study Abstract. This is a interesting finding which encourages one to intake more dairy products in ones diet. Looking critically into the study we find facts that should be taken into account.

The study included a study population between age 40 through 79 years. The older population is known to have increased prevalence of periodontal disease and osteoporosis. Research has shown relationship between osteoporosis and alveolar bone loss. Decreased mineral density in body including jaw bone would leave alveolar bones more susceptible to periodontal disease.

The study included dairy products like milk, cheese, and lactic acid foods (yogurt and lactic acid drinks). Lactic acid is known to increase calcium absorption in intestine. Consumption of foods rich in lactose is bound to produce more lactic acid, lowering the local pH, bringing it to ideal level of calcium absorption. Research has shown the correlation between poor absorption, decreased intake of lactose and poor absorption of calcium, a factor which can lead to the development of osteoporosis and fractures.

Another interesting fact about Lactic acid bacteria (LAB) is that they are immuno-modulatory and stimulate the nonspecific host defense mechanism. This results in increased phagocytic activity and release of immunological molecules such as secretory IgA which acts against pathogens. Some of the lactic acid bacterial strains are shown to produce biosurfactants. These surfactants exhibit strong adhesive properties against some of the known oral bacteria like S.mutans, S.epidermidis, C. albicans to various substrata. These surfactants coat the substratum and thereby change the physiochemical properties of it. This in turn would interfere with the adhesion of the target strains, either inhibiting their adhesion or releasing bound cells, which could affect the composition of the plaque formed. Therefore presence of more number of LAB in the oral cavity could act as probiotic and be beneficial.

So definitely consumption of foods rich in lactic acid (Dairy foods) would benefit us in improving our oral and general health in more than one way…..So next time just remember to have more cheese on your pizza!!.

its quiet a an astounding finding in this study... but i have doubt its applicability based on the fact that the effect of these products on the overall health of the patient, which is definately a downer for the patient. hence we just cant advice the patient to have these "high calorie products"... can we???
