[A comparative morphological description of the gingival and buccal epithelium in females in various phases of the menstrual cycle].

Computer morphometry was used to analyze morphologically and histochemically the smears of the gingival and buccal epithelium obtained from women at the secretion and proliferation phases of the menstrual cycle. A variety of reliably statistic differences conditioned by a menstrual-cycle phase was found to be typical of the gingival epithelium. A high percentage of epitheliocytes of differentiation terminal stages as well as signs of enhanced protein-synthesizing processes were typical of the cells ratio in the gingival epithelium at the secretion phase.

[Morphological and cytochemical features of the gingival mucosal epithelium in women during different phases of the menstrual cycle].

Morphological analysis of smears of the gingival epithelium by computer-aided morphometry was carried out in women during the secretory and proliferation phases of the menstrual cycle. During the secretory phase the cell ratio was characterized by higher percentage of epitheliocytes in the terminal stages of differentiation. Size of the nuclei and cytoplasm of intermediate cells, concentration of total protein in them, number of the nucleolar organizer zones, and degree of bacterial contamination of epitheliocytes is higher during the secretory phase than during the proliferation phase.

[The effect of a low-intensity helium-neon laser on succinate dehydrogenase activity in unmineralized periodontal and dental tissues].

Laser effects with energy density of 28.8, 86.4, 144 J/cm2 and 86.

[The effect of the light from a helium-neon laser on normal dental enamel solubility and in caries].

Effects of He-Ne laser radiation at a wavelength 0.63 micron for 90 sec on dental enamel mineral metabolism were studied from Ca, P levels and Ca/P ratio in 67 children aged 3 to 7. Ca and P solubility in surface enamel layers was found reduced after He-Ne laser irradiation in both healthy children and those with caries.
