Microrespirometer Technique for Study of Human Gingival Tissue

Abstract

Unmodified (Manhold, Bolden, and Katz), and modified (Senter, Eiler, and Lee) microrespirometer techniques were used. Results show (1) the QO2 appeared to hold relatively constant; i.e., 1.44[plus or minus]0.44 for 55 samples. These results also appear in accord with those obtained by use of the well-standardized Warburg Mano-metric technique in gingival tissue study; (2) there was no statistically significant difference between results obtained by use of the modified and unmodified microrespirometers (critical ratio=0.81), and(3) a standardized procedure for use of microrespirometers in studying metabolism of gingival tissue samples is feasible.
