Bacteriological and clinical assessment of tetracycline as root conditioning in adjunct to periodontal surgery.

The present study was conducted on 14 quadrants from seven solicited patients. After initial phase of plaque control, six different clinical parameters were recorded and scaling and root planning performed. In each of the seven patients two Modified Widman flaps were done. One served as a control and the other as experimental in which irrigation by Tetracycline-Hcl solution 100 mg/ml for 5 minutes was performed. On comparing the two treatment modalities the tetracycline-Hcl root conditioning showed a better improvement in all the clinical parameters tested. Tetracycline irrigation gave less bacterial counts than the control group right after irrigation, however after two weeks the bacterial counts increased again and were insignificantly different in the two groups.

Prepubertal periodontitis: a genetic analysis.

Genetic factors were recognized as possible predisposing factors in the etiopathogenesis of prepubertal periodontitis (PP). Consequently, the present work was carried out to determine the possible mode of inheritance and if there were any associated chromosomal aberrations in cases with PP. The study included 3 families with probands manifesting PP (the families included 18 individuals). Pedigree analysis was carried out as well as chromosomal analysis. The results pointed out to the possibility of new mutations arising due to various environmental factors (including the use of pesticides and their handling), in addition to a possible autosomal recessive inheritance. Chromosomal analysis showed no association between a certain chromosomal aberration and PP. An interesting finding was that a girl proband proved to be Xo female, i.e. a case of Turner's syndrome. This could be considered the first report of Turner's syndrome with PP.

A study of carboxyhaemoglobin levels of cigarette and sheesha smokers in Saudi Arabia.

A single carboxyhaemoglobin (COHb) estimation of late evening blood sample among non-smokers, cigarette smokers, and sheesha smokers was evaluated among Saudis. The COHb level in smokers of 15 to 40 cigarettes a day ranged between 0.7 and 10.3 with a mean value of 6.1 +/- 2.58 COHb. Values among sheesha smokers ranged between 6.5 and 13.9 with a mean value of 8.8 +/- 1.83, significantly higher than those of cigarette smokers (P less than 0.001) for a given degree of exposure to tobacco smoke.
