The unpleasant feeling of pain prevents patients from visiting the dental office. This pain also occurs during scaling، leading to aggravation of periodontal diseases. The aim of this research was to campare the effect of oral ibuprofen and local lidocaine gel on pain relief during scaling and root planing. In this single-blind clinical trial، 80 patients with mild-to-moderate periodontitis، who needed scaling، were selected from the Department of Periodontology، Faculty of Dentistry and divided into four groups. Iboprofen، placebo tablet، lidocain gel and placebo gel were used in groups 1-4، respectively، during scaling. Patients marked the severity of pain after the treatment by VAS index. Data were analyzed with SPSS 11. 5 using ANOVA، and Kolmogorov-Smionov and Tukey tests (α = 0. 05). The mean pain score in the lidicaine gel group (1. 80) was significantly lower than those in other groups (p value = 0. 023). The mean pain score in the placebo gel group (3. 90) was higher than the other groups (p value = 0. 023). Under the limitations of this study، use of lidocain gel to reduce the pain during scaling was more effective than systemic administrarion of Iboprofen tablet.

The aim of the present study was to compare some clinical parameters in patients with mild to moderate periodontitis treated by SRP with the use of 20 mg of doxycycline. In this randomized double-blind clinical trial، 44 patients with mild to moderate periodontitis were treated with standard SRP therapy. Then the patients randomly received either adjunctive 20 mg of doxycycline or a placebo twice daily for 3 months. Before and after treatment clinical parameters، including periodontal pocket depth (PPD)، clinical attachment loss (CAL)، bleeding on probing (BOP) and modified gingival index (MGI)، were recorded. Data were analyzed using SPSS software and Mann-Whitney test، paired t-test and chi-squared test (α = 0. 05). Clinical parameters of both case and control groups significantly improved during the study (p value < 0. 001). Doxycycline-treated group exhibited significantly higher PPD reduction، increased clinical attachment gain، and BOP and MGI reduction compared to the placebo group after 3 months (p value < 0. 001). Under the limitations of the present study، 20 mg of doxycycline as an adjunct to SRP resulted in significantly greater clinical benefits compared to SRP alone in the treatment of mild periodontitis.

Despite evidence of excellent results of implant therapy, peri-implant diseases do occur. The aim of this clinical study is to evaluate the efficacy of the closed surface scaling on clinical indices in the treatment of Peri-Implant Diseases. 10 subjects with 15 different sites of peri-implant diseases (including peri-implantitis and peri-implant mucositis) were selected. The sites were treated with closed surface scaling alone. Clinical indices including; Clinical Attachment Loss (CAL), Probing Pocket Depth (PPD), Bleeding On Probing (BOP), Gingival Index (GI), were evaluated at baseline and 1.5 and 3 months following therapy. Data was analyzed using Wilcoxon signed-rank test. Out of female and male with age of 52.8±7.33, the mean CAL changed from 7.16 ± 1.4 at baseline to 7.17 ± 1.4 at 1.5 months after treatment and 7.18 ± 1.5 at 3 months after treatment. Also the mean PPD changed from 5.08 ± 1.47 at baseline to 5.09 ± 1.5 at 1.5 months after treatment and 5.08 ± 1.5 at 3 months after treatment. There were no statistically significant differences in mean CAL and mean PPD (p < 0. 9). Bleeding scores and GI were not significantly reduced, at any time point (p < 0. 9). This study demonstrated that closed surface scaling alone, is insufficient for the treatment of peri-implant diseases and the adjunctive use of antimicrobial agents is recommended.

The aim of this study was to compare the efficacy of air-polishing devices (APDs) with hand instruments and ultrasonic scalers when used for interdental subgingival plaque removal. Likewise, the effectiveness of APD with and without abrasive powder was evaluated. A total of sixty single-rooted teeth were treated in fifteen periodontal patients with 4-6mm mesial probing depth (PD). The selected procedures were hand instruments (Gracey curettes), ultra sonic scalar, APD without powder and APD with powder. Before and immediately after the treatment procedures, subgingival plaque samples were collected from the mesial aspects of these teeth. The anaerobe cultivation method was utilized to assess the mean reduction of total colony forming units (CFU) immediately after treatment. Subgingival microorganisms were significantly reduced in all methods. The mean CFU differences between before and after treatments were significant (P<0.001) for all procedures. However, no significant difference was observed in the effectiveness of various methods. On average, all methods were able to reduce subgingival microorganisms by 92%. There was also a positive correlation between the colony counts before and after treatments (r= 0.52). Using APD is as effective as hand instruments and ultrasonic scalers for interdental subgingival plaque removal in cases with up to 6mm probing depth. The use of abrasive powder does not enhance the effectiveness of APD in subgingival plaque removal.

Systemic disease is often closely linked to the state of the oral cavity. One of thesesystemic diseases is diabetes mellitus. The purpose of this study is to determine the effect of scaling androot planning and mouth rinse on blood sugar level in type 2 diabetic patients.Methods and Materials: 30 uncontrolled type 2 diabetic patients suffering from sever chronicperiodontitis were selected and divided into two groups; each group consisted of 15 patients: Firstgroup (control): received oral hygiene instruction. Second group (case): received scaling and rootplanning plus oral hygiene instruction and chlorhexidine degluconate mouthrinse. In all groups,probing depth (in 6 sites of each tooth), bleeding index (in 4 sites of each tooth), fasting blood sugarand glycated hemoglobin were measured at first and three months after treatment. Then the before andafter treatment results were compared. Mean fasting blood sugar in second group, reduced from 184.2 to 163.87 mg/dl. Glycatedhemoglobin in this group reduced from 8.78% to 7.29% (p<0.05). Bleeding index, plaque index andprobing depth reduction were statistically significant before and after treatment (p<0.05). Phase one periodontal therapy improves periodontal conditions and reduces fastingblood sugar and glycated hemoglobin.

Scaling and root planing is one of the most commonly used procedures during periodontal treatments. Removal of calculus using conventional hand instruments is incomplete and rather time consuming. To find more efficient and less difficult instrumentation method, investigators have proposed lasers as an alternative or adjunct to hand instruments for scaling and root planing. The aim of the present study was to compare the effectiveness of three methods of hand instruments, ultrasonic and Er:YAG laser for scaling & root planing of root surfaces with SEM method.Methods and materials: This was an experimental study and samples included 15 extracted premolars collected from patients with periodontal problem. The teeth were sectioned in two parts vertically. Therefore 30 samples were randomly divided in two groups. In the first group each surface of root from CEJ was divided in two parts. One part was scaled with manual curret and another by Er:YAG laser and third group was cleaned by ultrasonic methods. Another surface was considered as control group. The surface changes were evaluated by SEM in magnification of 50, 400 and 750 by 5 Examiners. Data was analyzed by SPSS program. The findings show that surface roughness is more in control group comparing with three other groups. Besides roughness from the most to the least belong to: ultrasonic group, laser group & manual scaling group. Kruscal-wallis test & Mann-Whitney test showed that there was a significant difference in the amount of surface roughness between manual group & laser group and also between control group & other groups and between manual and ultrasonic group. But there was no significant difference between rate of surface roughness in laser and ultrasounic group. The efficacy of Er:YAG laser for scaling & root planing is not more than manual and ultrasonic instruments the amount of surface roughness created by Er:YAG is more than manual scaling but the difference is not significant comparing to ultrasonic scaling.
