- Abstract: Objective We?detected?and?analyzed?the?clinical?values?of?total?protein?(TP),?albumin?(ALB),?globulin?(GLB),?and?ALB/GLB?ratio?(A/G)?of?whole?unstimulated?saliva?of?healthy?people?to?determine?the?time?of?day?when?saliva?composi-tion?is?relatively?stable.?We?compared?the?protein?concentration?and?A/G?of?whole?unstimulated?saliva?of?patients?with?chronic?periodontitis?with?those?of?healthy?volunteers?to?provide?references?for?diagnostic?methods?and?clinical?applications?of?saliva.?Methods???The?whole?saliva?of?37?healthy?subjects?were?collected?at?8:00,?9:30,?11:30,?13:00,?16:30,?and?21:00.?Meanwhile,?the?whole?saliva?of?24?patients?with?periodontitis?was?collected?in?the?morning.?Bicinchoninic?acid?method?was?used?to?detect?the?TP?content.?Saliva?ALB?was?detected?by?GF-D800?semi-automatic?biochemical?analyzer,?and?the?GLB?and?A/G?were?cal-culated.?Finally,?the?results?were?statistically?analyzed?using?SPSS?19.0.?Results???Salivary?protein?compositions?were?stable?in the morning on an empty stomach. Healthy people:TP, (1 354.35±389.52)μg·mL-1;ALB, (139.55±27.19)μg·mL-1;?GLB,?(1 211.80±360.73)μg·mL-1;A/G, 0.126 3±0.041 7. Subjects with chronic periodontitis:TP, (2 611.56±231.62)μg·mL-1;?ALB,?(296.27±17.34)μg·mL-1;GLB, (2 315.69±221.67)μg·mL-1;?A/G,?0.156?2±0.017?3.?The?contents?of?TP,?ALB,?and?GLB?in?healthy?individuals?at?different?periods?within?a?day?showed?significant?differences?(P<0.05),?which?were?mainly?reflected?in?the?levels?before?and?after?meals.?No?significant?difference?was?detected?in?A/G.?The?concentrations?of?TP,?ALB,?and?GLB?were?significantly?increased?in?patients?with?chronic?periodontitis?compared?with?those?in?healthy?volunteers.?However,?no?significant?difference?existed?in?A/G.?Conclusion???Salivary?protein?compositions?are?more?stable?in?the?morning?than?in?other?periods.?Thus,?mornings?can?be?set?as?the?time?of?specimen?collec-tion?in?future?research.?The?concentrations?of?TP,?ALB,?and?GLB?in?patients?with?chronic?periodontitis?are?higher?than?those?in?healthy?people.
