In the present study, it was concluded that gingival thickness varies according to age, gender and dental arch.

Background:Bacteremia frequently occurs after treatment procedures such as extractions, scaling, root planing, periodontal surgery. There is currently significant interest in the possibility that bacteremia with oral bacteria may play role in pathogenesis of atherosclerosis. There are well-conducted studies that have determined the frequency of passage of periodontal microorganisms to the bloodstream after periodontal treatment. There is scarce information related to the incidence of periodontopathic microorganisms during bacteremia induced by this procedure.Aim:The aim of this study was to establish the frequency of passage of periodontopathic microorganisms in peripheric blood after scaling and root planing in patients with periodontitis.Materials and Methods:Forty subjects with chronic periodontitis were included in the study. Blood samples were drawn from each patient at following intervals pre-treatment i.e., before SRP (P1), immediately after SRP (P2), and 30 minutes after SRP (P3). Following SRP, blood samples were analyzed for following microorganisms: Porphyromonasgingivalis, Tannerella. forysthus, Eikenellanella. corrodens, Campylobacter species, Micromonas. micros, and Prevotella. intermedia.Statistical Analysis Used:Chi-square test.Results:Bacteremia was found in 70% (28/40) immediately after SRP and after 30 min, it was reduced to 25% (10/40) and 7.5% (3/40) presented bacteremia before SRP.Conclusions:It was concluded that bacteremia frequently occurs immediately after SRP with P. gingivalis showing the highest frequency in blood.

Aim:The aim of this study was to evaluate the influence of manual versus mechanical glide path (GP) on the surface changes of two different nickel-titanium rotary instruments used during root canal therapy in a moderately curved root canal.Materials and Methods:Sixty systemically healthy controls were selected for the study. Controls were divided randomly into four groups: Group 1: Manual GP followed by RaCe rotary instruments, Group 2: Manual GP followed by HyFlex rotary instruments, Group 3: Mechanical GP followed by RaCe rotary instruments, Group 4: Mechanical GP followed by HyFlex rotary instruments. After access opening, GP was prepared and rotary instruments were used according to manufacturer's instructions. All instruments were evaluated for defects under standard error mean before their use and after a single use. The scorings for the files were given at apical and middle third.Statistical Analysis Used:Chi-squared test was used.Results:The results showed that there is no statistical difference between any of the groups. Irrespective of the GP and rotary files used, more defects were present in the apical third when compared to middle third of the rotary instrument.Conclusion:Within the limitations of this study, it can be concluded that there was no effect of manual or mechanical GP on surface defects of subsequent rotary file system used.
