INCIDENCE OF THE SALIVARY FLOW AND Ph IN DENTAL CAVITY

The individual risk of cavity is related with the quantity of saliva taken place by unit of time and the pH of the saliva.The controls  buccal hygiene by means of quantitative detection of the tray  by means of index of bacterial badge they are not enough, since the decisive factor so that the  cariosa lesion appears it is the quality and not the quantity of badge.  It is considered as an factor advantage of the cavity an inferior salivary flow to 1 ml/minut. For the same reason the figures of inferior salivary pH at 4 (four) it increases the cavity risk. This work had as objective to quantify one of the factors of risk of the illness cavity in the temporary teething and its relationship with its permanency in the first permanent molar -. The study was carried out on a population of 100 children among 6 and 9 years of both sexes that converged to the Subject Dentistry Integral Children of the F.O.L.P. to determine the quantity of saliva in quantitative terms, it was measured by the produced quantity after chewing a block of paraffin during 5 minutes. The produced saliva is picked up by means of a funnel in a rehearsal tube and of there the quantity is determined in ml/minut. For the determination of the salivary pH  was carried out the test Dentofuff, mixing a certain quantity of saliva with a solution acid standarizated. The obtained coloration is compared on a chromatic scale to know its pH. The results were processed in calculation leaf Excel 2000. Comparing the data obtained:sexo masculine 48%, feminine 52%, age: 6 years: 25%, 7 years: 30%, 8 years: 25%; 9 years: 20%; quantity of saliva, average 5.0125; medium 5; standard deviation 0.7249. pH average 3.62; medium 4; standard deviation 1.1325. ceos average 7.45; medium 8; standard deviation 1.5887. CPOS average 3.75; medium 4; standard deviation 1.6131. correlation Coefficient between quantity of saliva and index ceos 0.4430; with the index CPOS 0.1995. Among pH - index ceos/CPOS, 0.1494; 0.1396. * * The obtained results demonstrated that the decrease of saliva and the low pH are factors of risk of caries.Words keys:  salivates -  decay - cariogenical risk .
