We studied saliva sample of 134 persons of both sex; including healthy persons and patients with periodontal disease. We researched the saliva's pH variations and found Lie at alkali pH in the patients with periodontal disease and different saliva pH between men and women.

There are inconsistent data about the association between saliva properties, dental caries, and periodontal status. In this study, we tried to examine the association between dental caries and periodontal status with salivary viscosity, flow rate, pH, and buffering capacity in adults.In the present cross-sectional study, 450 female teachers were randomly selected from schools located in Yazd, Iran. Oral examinations were conducted, and unstimulated saliva samples were collected. Salivary viscosity, flow rate, pH, and buffering capacity were assessed. The salivary physicochemical properties were compared among teachers with different types of oral health. Analyses were done using the Statistical Package for the Social Sciences version 16.In total, 431 female teachers aged 40.45 ± 8.18 years were included in the study. Salivary flow rate, buffering capacity, pH, and viscosity, community periodontal index status were not significantly different in participants with and without tooth caries. There was a reverse linear association between salivary pH and flow rate with the decayed, missed, and filled teeth index (P < 0.05). The saliva buffering capacity was not significantly related to dental properties. Those with bleeding on probing had lower salivary pH, and buffering capacity compared to those with healthy gum. However, the salivary resting flow rate was not different in participants with bleeding on probing and healthy participants.Based on our results, saliva properties might be important predictors in oral health status. This means that any change in saliva combination might affect periodontal and dental diseases. Future prospective studies are recommended to confirm these results.

Evidence of postoperative complications associated with smoking has varied. We conducted this study to clarify the relationships between tobacco smoking and postoperative complications following craniotomy.A retrospective cohort analysis identified 800 patients who underwent cranial surgery with general anesthesia at a medical center with 2700 beds in Seoul, Korea between January and December 2011.Prior smokers (34.8%) and current smokers (35.1%) were hospitalized for at least 11 days longer than never smokers (25.5%) (x2 = 6.74, P=0.036). There were no statistically significant differences in the incidence of postoperative complications among never smokers (5.2%), prior smokers (9.6%), and current smokers (9.6%). The incidences of postoperative complications among prior smokers (9.6%) and current smokers (9.6%) were similar. Comparisons between never smokers (25.5%) and current smokers (34.9%) showed smokers had longer hospital stays and a higher incidence of complications (χ2=6.74, P=0.012). The incidence of major complications (χ2=5.27, P=0.024) and overall complications (χ2=4.84, P=0.033) were also significantly higher among smokers than never smokers. The impact of smoking status on postoperative complications was not identified.We found significant associations between smoking status and postoperative complications. The incidence of major complications was twice as high among smokers as among never smokers. Therefore, it is recommended to continuously monitor current smokers to prevent postoperative complications after craniotomy.

Summary The development of postoperative deep vein thrombosis (DVT) was determined in 50 South Indian patients aged 50 years or more using the 125I-fibrinogen uptake technique. The overall incidence was 28 per cent. In patients with malignancy the incidence was 47·6 per cent. Predisposing factors such as varicose veins, oral contraceptives and obesity did not appear important. A retrospective analysis of post-mortem examination performed on 432 patients dying after operation showed major pulmonary embolism to have occurred in only 1·9 per cent. The disproportion between the frequent ocurrence of postoperative DVT and the infrequence of fatal pulmonary embolism warrants further study.

Abstract Objective Periodontal pathogens in dental plaque are the main causative agents of periodontitis and peri‐implantitis. Detection of the presence of such periodontal pathogens early would serve as a useful tool in the diagnosis and treatment of this disease. Therefore, the purpose of this study was to investigate whether the periodontal pathogen levels in saliva were correlated with the periodontal status of patients receiving implant treatment. Materials and Methods A total of 291 patients visiting Tokyo Dental College Chiba Hospital were divided into four groups: a no‐periodontitis (np) group, a mild‐periodontitis (mip) group, a moderate‐periodontitis (mop) group, and a severe‐periodontitis (sp) group. The levels of the following five periodontal pathogens in saliva were evaluated using real‐time polymerase chain reaction: Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Treponema denticola , and Prevotella intermedia . Results The levels of P. gingivalis and T. forsythia were significantly higher in mop group than in np group ( P < 0.05). The levels of all periodontal pathogens tested except A. actinomycetemcomitans were significantly higher in sp group than in np group ( P < 0.05). Conclusion The detection levels of the periodontal pathogens targeted in saliva samples were correlated with the periodontal status. This suggests that using saliva to screen for periodontopathic bacteria offers an easier‐to‐use clinical tool than the paper point method in the diagnosis and treatment of periodontitis and peri‐implantitis.
