Antioxidants and Periodontal Diseases

Excessive reactive oxygen species production plays an important role in the pathogenesis of various chronic inflammatory diseases, including periodontal disease. Reactive oxygen species could damage the cells and the tissues. In the pathogenesis of periodontal diseases, the increased PMN count and activity cause a high rate of ROS release. This leads to increased oxidative stress in periodontal tissues. Periodontal tissues require adequate levels of antioxidants to prevent tissue damage caused by reactive oxygen species. The use of antioxidants in the treatment of periodontal disease and periodontal health has gained importance in recent studies. Antioxidants can be used to treat periodontal disease locally or systemically. Therefore, this chapter focuses on the effects of antioxidant on periodontal tissues

Evaluation of dental anxiety in patients undergoing second-stage surgery with er, cr: YSGG laser treatment: Randomized clinical trial

Oral surgical procedures cause high-pain expectation and consequent anxiety in patients. The aim of this study is to compare the effects of Er, Cr: YSGG laser and scalpel method on dental anxiety level during second-stage implant surgery. 96 patients with 304 osseointegrated implants were divided into two groups. Implants embedded under the oral mucosa were exposed with scalpel or laser surgery. Before the operation the patients were asked to fill the STAI and DAS while resting in the waiting room. In addition, postoperative daily analgesic use, VAS scores perioperativly and on the postoperative 1st, 2nd and 3rd days and demographic information such as age and gender were also recorded. There was no statistically significant relationship between surgical method and anxiety levels (p>0.05. Also, the differences between the scalpel and laser groups in terms of total DAS and STAI scores were statistically insignificant (p>0.05). But statistically significant difference was found between surgical method and the analgesic consumption (p<0.05). A higher rate of analgesic consumption was observed in the scalpel group. The use of Er,Cr;YSGG laser could reduce pain during minor oral surgical procedures but had no significant effect on dental anxiety. Different modalities that could provide additional benefits in overcoming this situation should be investigated. © 2020, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved

Efficacy of gaseous ozone in smoking and non-smoking gingivitis patients.

BACKGROUND The gingivitis treatment protocols aim to stop the progression of inflammation and prevent the affliction of deeper periodontal tissues. Current research focuses on novel methods that can be applied with handheld and ultrasonic devices to increase the effectiveness of non-surgical periodontal treatment. Ozone has been shown to have a strong antimicrobial effect against bacteria that play a role in the etiology of gingival/periodontal diseases. Research evaluating the effects of ozone gas on the treatment of gingival tissues is limited. AIM We investigated the effects of ozone application during the scaling procedure on clinical parameters of gingivitis in smokers and non-smokers and to investigate the efficacy of ozone gas in periodontal treatment. METHODS A total of 40 subjects, 27 males/13 females-20 smokers/20 non-smokers-with plaque-induced gingivitis, were selected. The patients underwent a single session of full-mouth supragingival and subgingival scaling. Gaseous ozone application was performed on a randomly selected maxillary quadrant. The other maxillary quadrant was designated as the control group receiving only initial periodontal treatment. Clinical parameters, such as PI, GI, GBTI, and PPD, were measured before and 1 week after treatment. RESULTS Our study shows that ozone therapy significantly improves clinical parameters in smokers and non-smokers when applied in addition to periodontal therapy. CONCLUSIONS Additional studies comparing the effect of ozone therapy on smokers and non-smokers to the effects of oral mouthwashes may provide valuable contributions to the field
