Analysis of the stimulated whole saliva in overweight and obese school children

Abstract

SummaryObjective. To determine if some stimulated whole saliva parameters are influenced by an increase of Body Mass Index. MethOds. Controlled cross-sectional study involving 90 school children of both genders between 7 and 10 years of age, from Bragança Paulista -SP. Three groups were formed: overweight, obese and control. Body Mass Index and diet intake by the Food Register method were evaluated. The salivary pH, flow rate, buffer capacity, protein, phosphate, calcium, fluoride, total and free sialic acid, and peroxidase activity were determined. Results. The overweight and obese groups showed greater energy and lipid intake (P< 0.001) than the control group. There was no difference in the saliva flow rate between groups, however only the control group showed a mean value considered normal. In the overweight and obese groups a decrease in both the concentration of phosphate (P< 0.001) and peroxidase activity (P<0.001) was observed. In the obese group an increase in the concentrations of free sialic acid (P= 0.004) and protein (P= 0.003) occurred. cOnclusiOn. Overweight and obese children show alterations in the concentrations of phosphate, free sialic acid and proteins, and in the peroxidase activity that are favorable conditions for dental caries.

Changes in the salivary protein profile of morbidly obese women either previously subjected to bariatric surgery or not

“…Because saliva composition is influenced by gender [21], only women were selected as subjects for the present study. A higher total protein concentration was observed in the saliva of obese individuals who had not been subjected to bariatric surgery, in line with reports on obese children and adolescents [34], and men [36]. Interestingly, women who had been subjected to bariatric surgery did not present increased levels of total salivary proteins, as compared to the control group, suggesting that weight loss may reverse such salivary change.…”

Hubungan Body Mass Index dengan Laju Aliran Saliva (Studi pada Mahasiswa Fakultas Kedokteran Gigi Universitas Andalas)

“…3 Apabila laju aliran saliva berkurang maka terjadilah peningkatan jumlah bakteri penyebab karies seperti Lactobacilus dan Streptococcus mutans. 4 Laju aliran saliva juga berkontribusi dalam perkembangan penyakit periodontal dan infeksi oral seperti candidiasis. 5 Pada individu dengan laju aliran saliva yang rendah, bacterial clearance menjadi berkurang sehingga kolonisasi bakteri periodontitis seperti Streptococcus constellatus, Eubacterium nodatum, Porphyromonas gingivalis, dan Actinobacillus actinomycetemcomitans di jaringan rongga mulut meningkat.…”

Obesidade e saúde bucal: impacto da obesidade sobre condições bucais

“…Outro fator que parece estar envolvido na associação entre cárie e obesidade é a composição salivar. Segundo Pannunzio et al 22 (2010), crianças obesas apresentam alterações na composição da saliva, o que é favorável ao surgimento de cáries. Essa diminuição do fluxo salivar deve-se ao déficit de proteínas na alimentação, visto que crianças obesas ingerem muitos carboidratos e muitas comidas altamente industrializadas, e poucos alimentos ricos em proteínas 18 .…”
