CONTERO MEJIA, Paola  e  CABRERA DAVILA, Ma. José. CORRELATION BETWEEN PH SALIVAL AND DENTAL CARIES IN PATIENTS WITH DOWN SYNDROME THAT COME TO THE NATIONAL ARMADA ASSISTANCE FOUNDATION, GUAYAQUIL, ECUADOR-2016. Conrado [online]. 2018, vol.14, n.61, pp. 15-20. ISSN 1990-8644.

The aim of this study is to determine the correlation between salivary pH and dental caries in patients with Down syndrome who came to the Fundacion Asistencial Armada Nacional (FASAN) - Guayaquil. Materials and methods: In this research there was a sample of 58 individuals between the ages of 4 and 25, both genders. Salivary pH was measured placing sublingually pH indicator strips. Surveys of dietary habits for parents and a complete diagnosis of caries and plaque index was also performed. It was observed that 50% of patients with down syndrome had a neutral initial salivary pH, without a great difference 43% where at an acid salivary ph. unlike the salivary pH that was taken after 10 minutes of the ingestion of sugar beverages, acidic pH prevailed with 83% related to the amount of caries found in the sample within the ranges (low risk of caries 57% and moderate 22%) and plaque present in 59% with level 2 of dental plaque. we found a higher risk in caries in males with a 59% and the age range that was most affected was 12 to 18 years. There is a close relationship between acid salivary pH and caries present in the mouth as it was found that all patients suffered from dental caries with a prevalence between low and moderate levels of caries risk, with a high level of dental plaque (level 2 of dental plaque) due mainly to poor oral hygiene.
