LLLT as an adjunctive therapy to non-surgical periodontal treatment improves periodontal healing.

Dentin demineralization is not time dependent at all concentrations of tetracycline HCI.

Our clinical index scores were related to the educational level of the study population. When the educational level of the study group decreased, the plaque, gingival index, and probing depth scores contrarily increased. Also non-attendance for previous periodontal care increased the scores of plaque index and probing depth. In view of the results of our study, it might be suggested that simple preventive oral hygiene programs may help maintain healthy gingiva during pregnancy.

The periodontal status of 77 diabetic children and adolescents, and 77 paired, systemically-healthy, sex- and age-matched control subjects, was clinical examined. Fasting blood glucose, fructosamine and glycosylated haemoglobin (HbA1) values were determined. The mean periodontal pocket depths, clinical attachment levels and the parameters to assess diabetes mellitus from the diabetic group were significantly higher than those of the controls. We found a positive correlation between the duration of diabetes and clinical attachment loss, but not with periodontal probing depth, plaque index and gingival index in the diabetic group. A positive correlation was also assessed between the present serum fructosamine and gingival index in the diabetic group, but not in controls.

Inflammatory periodontal diseases are related to dental plaque formation. Increase in the perfusion of the inflamed tissue results in increased oxygen supply. Although oxygen has healing effects, it is bound to be a mediator of peroxidation in biological membranes. Chemotherapeutic agents such as chlorhexidine, listerine, sanguinarine, and cetylpridinium chloride and oral antibiotics such as tetracycline HCl and doxycyline were tested for their antioxidative activities. While doxycycline has the highest antioxidant activity in lower volumes (0.1 ml), sanguinarine, listerine and a pace after them, tetracycline HCl, had similar effects in higher volumes (0.3 and 0.4 ml). The results showed that in addition to their antiseptic or antimicrobial effects, these preparations have an antioxidative activity against spontaneous oxidation.
