Objective To improve the traditional treatment of retrograde pulpitis, using Periocline adjuvant therapy, to evaluate its clinical effect.Methods From January 2015 to 2017 in January, our hospital 70 patients treated with retrograde pulpitis.The patients were randomly divided into two groups.The observation group of 35 cases, adopt the traditional treatment methods (periodontal treatment and dental pulp treatment), 35 cases in the control group based on conventional therapy, the adjuvant treatment of periocline.The related indexes and treatment effects were observed.Results After treatment, the indexes of the two groups of patients were significantly decreased compared with the control group[(1.57±0.50),(3.37±1.88),(4.89±1.60),(5.31±1.39)],the observation group decreased much more[(0.79±0.24),(2.01±1.14),(4.01±1.38),(4.11±0.62)], the difference was significant (P<0.05).At the same time, the effective rate of the observation group was 94.29% (33 cases), and the effective rate of the control group was 74.29% (26 cases), the difference was significant (P<0.05).Conclusion Based on conventional therapy, using Periocline adjuvant therapy, can improve the therapeutic effect of retrograde pulpitis, has significant value of application and promotion.

Objective To investigate the effects of minocycline hydrochloride ointment on collagenase in gingival crevicular fluid.Methods 60 patients with chronic periodontitis treated in our hospital from January 2015 to December 2016 were selected as the research object, the patients were divided into two groups according to their intervention methods, 30 cases in each group.The control group was treated with ultrasound clean governance and iodine glycerol, the observation group was treated with ultrasound clean governance and minocycline hydrochloride ointment The experimental data of the two groups were compared.Results The index change of gingival crevicular fluid volume plaque index,,depth of exploration and clinical attachment loss in the observation group were better than those in the control group, the difference between the two groups was statistically significant (P<0.05);The clinical therapeutic effect of the observation group(93.3%)was better than that of the control group(73.3%), and the difference between the two groups was statistically significant (P<0.05).The incidence of adverse reactions in the observed group(10.0%)was lower than that in the control group(26.7%), and the difference between the two groups was statistically significant (P<0.05).Conclusion Minocycline hydrochloride ointment can affect the level of collagenase in gingival crevicular fluid, and the clinical effect of the treatment of chronic periodontal disease is significant.

Objective To study the effect of minocycline hydrochloride ointment and ibuprofen on serum concentration of chronic periodontitis . Methods 86 patients with chronic periodontitis treated in our hospital from June 2014 to June 2016 were selected and randomly divided into two groups:observation group 43 cases, using minocycline hydrochloride ointment combined with ibuprofen treatment , the control group 43 cases, only the use of minocycline hydrochloride ointment for treatment.After treatment, the clinical efficacy of the two groups were observed, the level of plaque, the level of attachment, the level of gingival sulcus bleeding and the probing depth of periodontal pocket were recorded, the levels of IL-10, TNF-α, hs-CRP and IL-8 in serum and the incidence of adverse reactions were measured.Results The total effective rate was 90.7% in the observation group and 74.4%in the control group, which was significantly higher than that in the control group, the difference was statistically significant (P<0.05).The probing depth of the periodontal pocket, gingival sulcus bleeding index, attachment level and plaque index decreased to varying degrees in the two groups before and after treatment, the difference was statistically significant (P<0.05), patients in the observation group were significantly lower than those in the control group, the difference was statistically significant (P<0.05).After treatment, the levels of IL-8, hs-CRP and TNF-αin serum of the two groups decreased, IL-10 levels increased in different degrees, the difference was statistically significant (P<0.05).The observation group was better than the control group, the difference was statistically significant ( P<0.05 ) .Conclusion Minocycline hydrochloride ointment combined with ibuprofen has a good effect on patients with chronic periodontitis.It can effectively relieve the patient's condition and improve the serum concentration of patients.

Objective To explore and analyze the clinical efficacy and adverse reactions of total glucosides of paeony (TGP) and vitamin B2 in the treatment of recurrent aphthous ulcers (RAU) . Methods 120 patients of RAU were randomly divided into TGP group and vitamin B2 group, 60 cases in each group. The TGP group received TGP capsules after meals, three times a day, 0.6g/d. Vitamin B2 group received vitamin B2 tablets, three times a day, 5mg/d, 8 weeks for one course. The ulcer change, visual analogue scale (VAS) and efficacy were observed. Results After treatment, the VAS scores were significantly reduced in two groups(P<0.05), and the above indicators of TGP group were better than vitamin B2 group(P<0.05). The total efficacy in TGP group was higher than that in vitamin B2 group (P<0.05). There was minor adverse reactions in TGP group and no significant adverse reactions in vitamin B2 group.Conclusion TGP has good efficacy and safety in the treatment of recurrent aphthous ulcers. The TGP has significant effect than that of vitamin B2.
