Concentration of total protein and degree of acidity (pH) of saliva when fasting and after breakfasting

Abstract

Background: While fasting, the mouth does not work to eat and drink so that the salivary glands become less active so saliva production decreased and there was a change in eating timewhich is relation to the mastication process that impact on changes in the degree of acidity (pH) Objectives: To determine the concentration of total protein and the degree of acidity (pH) of saliva when fasting and after breakfasting. Materials and Methods: The study was observational analytic design with longitudinal (follow up study) conducted in the Hj. Halima Dg. Sikati Dental Hospital inKandea in July 2015, the sampling method was purposive sampling. Population was 35 clinical students at the Department of Dental Public Health, Faculty of Dentistry Hasanuddin University with a total sample of 16 students who fit the criteria of the study subjects. To calculate the total protein of saliva concentration using Kyltecautoanalyzerand pH meter to measure the acidity of saliva. Data was analyzed was using SPSS version 17.0 (paired t-test, p <0.05). Results: The mean of total protein (%) while fasting by 0135% ± 0.026 and the mean total protein (%) after breakfasting at 0.179% ± 0.035, while the average degree of acidity (pH) during fasting at 7.26 ± 0:24 and the average degree of acidity (pH) after breakfasting at 7.66 ± 0.23 with p-value (0.000). Conclusions: An increase in the total protein concentration and acidity (pH) after breakfasting.

Perbandingan Difluorosilane 0,9% Dan Kombinasi Sodium Fluoride 5% Dengan Tricalcium Phosphate Terhadap Perubahan Ph Plak Dan Ph Saliva Anak

“…Hal ini sesuai dengan penelitian Gemiani dkk (2018) dan penelitian Illahi dkk (2016) yang menunjukkan adanya penurunan pH plak pada kelompok kontrol tanpa diberikan perlakuan dan rata-rata pH saliva yang menjadi lebih rendah pada saat puasa. 17,18 Penurunan pH plak dapat dikaitkan dengan akumulasi plak yang terjadi dalam 1 jam setelah dilakukan profilaksis oral. Pembentukan plak dimulai 1 menit setelah gigi dibersihkan.…”

“…Hal ini menyebabkan kelenjar saliva menjadi kurang aktif dan produksi saliva menjadi berkurang, sehingga terjadi penurunan pada pH saliva. 18 Hasil penelitian menunjukkan aplikasi Difluorosilane 0,9% menghasilkan perubahan pH plak yang lebih rendah dibandingkan aplikasi kombinasi Sodium fluoride 5% dengan Tricalcium phosphate. Hal ini kemungkinan berhubungan dengan konsentrasi fluoride dalam plak.…”

Comparison of efficacy rinsing with cocoa seed extract, green tea catechins extract and lime extract to salivary ph in children suffering ECC (Early Childhood Caries)

“…The role of saliva is not only for the mastication process but also to protect the tissue inside the oral cavity. 5,6 In normal circumstances, salivary pH is about 6.8 to 7.2 but some types of carbohydrates are converted by bacteria and result in a decreased pH of the saliva. 7 Natural ingredients from plants in Indonesia can be used to inhibit this process.…”

Successful treatment of herpes simplex-associated erythema multiforme with a combination of acyclovir and prednisone

“…Its production and secretion is affected by stimulation, diet, fasting, age, sex, and medications. 2,3 Saliva analysis can determine one's body condition due to substances movement from blood to saliva through several mechanisms, such as passive diffusion, active transport, and ultrafiltration (gap junction). 4,5 Previous studies found that saliva analysis can determine Cystic Fibrosis, Sjogren's Syndrome, Squamous Cell Carcinoma, periodontal disease, stress, acute myocardial infarct, cholesterol, pancreatic cancer, and the disability to absorb Calcium.…”
