To study the effect of chlorhexidine combined with mechanical debridement on peri-implant inflammation and the influence on SF-36 score of patients.
One hundred patients with peri-implantitis admitted to Zhejiang Provincial People's Hospital from January 2015 to January 2019 were selected and randomly divided into control group and combined group with 50 cases in each group according to random number table method.Patients in both groups were treated with mechanical debridement, and patients in the combined group were gargled with chlorhexidine gargle apart from mechanical debridement. Plaque biofilm average activity and modified plaque index (mPLI), bleeding on probing (BOP), modified sulcus bleeding index (mSBI), probing the depth (PPD), clinical attachment level(AL) were measured before and after treatment. Sf-36 scale and VAS visual pain score were used to evaluate the quality of life and pain degree of patients, and the therapeutic effect and incidence of complications were assessed. The data were anaf peri-implantitis, which can effectively inhibit plaque biofilm activity and plaque formation, alleviate pain and improve the quality of life of patients.
To investigate the changes of salivary composition, flow and dry mouth in patients with head and neck squamous cell carcinoma after parotid sparing modulated radiation therapy.
One hundred and one patients with head and neck squamous cell carcinoma who received radiotherapy in Qingyang People's Hospital from May 2016 to November 2018 were selected and divided into intensity modulated radiation group(n=54) and conventional radiation group(n=47) according to different treatment methods. The clinicopathological parameters, parotid uptake index, salivary composition, dry mouth, oropharyngeal symptoms and grading were compared between the two groups. The data were analyzed with SPSS 20.0 software package.
The tumor site, TNM stage and differentiation had no significant difference between the two groups(P>0.05). The concentration of total protein, secretory IgA, calcium and phosphorus in saliva of patients in intensity modulated radiation therapy group were significantly higher than those in conventional rlated radiation therapy has little effect on salivary composition, flow rate and dry mouth, and has obvious protective effect on parotid secretion.
To investigate the osteosclerin level and bacterial distribution in periodontitis patients at different stages, and to analyze the correlation between osteosclerin and the parameters of conventional periodontal examination.
Patients with periodontitis admitted to Guangzhou Huadu Maternal and Child Health Hospital from March 2017 to June 2019 were selected and divided into stage Ⅱ group (n=27), stage Ⅲ group (n=42) and stage Ⅳ group (n=22) according to the severity of periodontitis; meanwhile, 30 healthy individuals underwent physical examination in our hospital during the same period were selected as control group. Gingival crevicular fluid and plaque at buccal and lingual sites were collected for bacterial culture. The expression of osteosclerotin in gingival crevicular fluid was detected by enzyme-linked immunosorbent assay. The data were processed by SPSS 23.0 software package. Spearman correlation analysis was used to analyze the correlation between BI grade and osteosclerin, and correlation between Ptitis at different stages are different. Detection of osclerosin level and identification of periodontal microorganism culture have high clinical value in clinical diagnosis of periodontitis severity and can provide reference for selection of subsequent treatment plan.
The expression level of osteosclerosin is closely related to PD, CAL and BI grades in patients with periodontitis, and bacterial colonization levels in gingival crevicular fluid and dental plaque in patients with periodontitis at different stages are different. Detection of osclerosin level and identification of periodontal microorganism culture have high clinical value in clinical diagnosis of periodontitis severity and can provide reference for selection of subsequent treatment plan.
The purpose of this study was to investigate the periodontal status in adult periodontal disease patients with malocclusion treated with digital clear aligners.
Thirty-three patients with periodontal disease who needed orthodontic treatment were selected. The patients were randomly divided into 2 groups, digital clear aligners group (experimental group, 16 patients) and fixed appliances group (control group, 17 patients). Bleeding index (BI), probing depth(PD), plaque index(PLI) and gingival index(GI) were recorded at baseline and 1, 3, 6 and 9 months during orthodontic treatment. SPSS 17.0 software package was used to analyze and compare the data of periodontal status between two groups.
1, 3, 6, and 9 months after orthodontic treatment, clinical parameters of the control group were significantly higher than baseline(P<0.05). The same measurements of the experimental group showed no significant differences at 1, 3, 6, and 9 months of treatment (P>0.05). After 1, 3, 6, and 9 months of treatment, the clinical parameters of BI, PLI and GI in the experimental group were significantly lower than the control group(P<0.05); PD in the experimental group was smaller than the control group, but there was no significant difference(P>0.05).
Compared with conventional fixed appliance, clear aligner of digitalization can more effectively maintain periodontal heath in adult periodontal disease patients with malocclusion.

To investigate the effect of testosterone level on inflammatory bone resorption in periodontitis with mice.
Forty-eight SD mice were randomly divided into unligated group, sham operation group, castration group, castration + testosterone group, 12 mice in each group. At 6 weeks after ligation, serum testosterone levels were measured, and alveolar bone loss (ABL) and alveolar bone absorption area were compared by hematoxylin - eosin staining and methylene blue staining. The expression of inflammatory cytokine messenger RNA(mRNA) in gingival tissue was measured by real-time fluorescence quantitative PCR. Lurbinectedin datasheet SPSS 20.0 software package was used to analyze the data.
Serum testosterone level among four groups was the highest in the unligated group, followed by castration + testosterone group, sham operation group and castration group, with significant difference(P<0.05). The ABL of the castration + testosterone group was significantly larger than that of the unligated group, the sham operation group and the castration group(P<0.
