Abstract
OBJECTIVE To find out factors influencing the compliance of supportive treatment of patients with periodontitis who have received implant restoration therapy. METHODS Patients who had completed periodontal and implant restoration treatment for more than 5 years in Department of Periodontology, Peking University Hospital of Stomatology were subjected to inclusion between March 2022 and August 2023.A questionnaire was compiled to gather the information including patients ' basic information (gender, age, and educational background etc.), smoking habits, general health conditions, oral hygiene habits, willingness to undertake periodontal and dental implant supportive treatment, actual fact on supportive treatment recorded in medical records, whether medical advices were correctly remembered, and reasons affected them to implement supportive therapy. The questionnaires were handed out to the above patients and filled during the process of follow-up treatment. Chi-square test, univariate and multivariate analysis of Logistic regression were employed to explore the correlations of these factors and the patients' compliance. RESULTS In the study, 92 patients and questionnaires were collected and analyzed. The results indicated that oral hygiene habits and whether medical advices were correctly remembered had significant correlation with compliance (P < 0.05). Time constraint (47.0%) and difficulty in appointment registration (24.8%) were the top 2 reasons obstructed them to undertake supportive treatment. Although the vast majority of the patients indicated willingness to perform follow-ups, 55.4% of them wouldn't come back until the dentist called them back. The results of our study also indicated that the patients placed significantly less importance on the health of natural teeth than implants. CONCLUSION In order to improve the compliance of supportive treatment, we suggest that dentists should put more emphasis on oral hygiene instruction, and knowledge regarding periodontitis should also be added as part of patient education contents. In the early stages of treatment, the patient should develop the habit of regular follow-up checks, More attention and patience should be given to elderly patients and those with lower level of education; use language that is easy to understand and printed medical instructions to help them remember. Patients can memorize better from refined doctors' advice, reinforcing care knowledge and refining medical advices can promote better follow-up treatment results. Motivating patients based on their characteristics is critical to improving compliance.

Abstract
The purpose of this study was to evaluate the periodontal status of patients who routinely did SPT, when compared to patients that did not SPT. This retrospective cohort study was conducted at a general dental office from 2001 to 2019. Patients aged 18 to 81 years who visited the dental office over a 10-year period were assigned into two groups: an SPT group, which included patients who continually visited the dental office for SPT one or more times every year, and an irregular group, consisting of patients who did not visit the dental office at least once a year. A total of 7307 teeth (SPT group) and 4659 teeth (irregular group) were evaluated, and the periodontal conditions were compared between the first and latest visits. Multiple regression analysis was used to analyze the results. The mean follow-up time was 13.74 years. The risk factors for improvements in probing pocket depth included age, sex, smoking, diabetes mellitus, molar tooth, and irregular SPT group (p < 0.001), and that for a positive bleeding on probing site was the irregular group (odds ratio 2.94; 95% confidence interval 2.63-3.29). This study showed that lack of routine in attending the SPT program significantly decreased the periodontal parameters, thus highlighting the importance of continuing with the program to maintain the periodontal health.

Abstract
OBJECTIVE Tooth loss affects quality of life. Scaling is a measure to prevent periodontal disease and tooth loss. This study aimed to determine the effect of scaling on tooth loss. BASIC RESEARCH DESIGN Secondary analysis of the Korean National Health Insurance Services database, comprising 514,866 Koreans as an initial cohort, followed for 14 years up to 2015. The study population comprised people who had received an oral check-up in 2002-2003. Using propensity score matching, we matched the intervention group (receipt of scaling) and controls (no scaling) 1:1. The outcome, tooth loss was defined as including all teeth except for third molars until 2015. The final sample included 94,738 people. Analysis used a Cox proportional hazard regression model. RESULTS Scaling showed conflicting results in univariate and multivariable analyses. In univariate analysis, people who received scaling were more likely to lose teeth (HR, 1.04; 95% CI, 1.02-1.05). After adjusting for confounders in the multivariable analysis, those who didn't receive scaling were more likely to lose teeth (HR, 0.97; 95% CI, 0.95, 0.99). The effects of scaling were identified in people without diabetes (HR, 0.97; 95% CI, 0.95, 0.99) but not in people with diabetes (HR, 0.97; 95% CI, 0.89-1.06). CONCLUSIONS Scaling was associated with less tooth loss. Regular scaling might be encouraged for vulnerable groups, such as males, older adults, lower income, handicapped, chronic diseases, and smokers.

Abstract
AIM The aim of this study was to evaluate combined efficacy of methylene blue mediated antimicrobial photodynamic therapy (a-PDT) using 660 nm diode laser versus Er, Cr: YSGG laser as an adjunct to scaling and root planing on improving the Probing depth (PD), Clinical attachment level (CAL), Plaque Index (PI) and Gingival Index (GI).clinical parameters in Supportive periodontal therapy. MATERIALS AND METHOD In this split-mouth, double-blind, randomized controlled trial, we compared a-PDT versus Er,Cr:YSGG as an adjunct to scaling and root planning (SRP) with SRP alone in Supportive periodontal therapy. A total of 36 subjected were enrolled. In each patient, two quadrants constituted the control group (Group I - Scaling and root planing SRP alone), one site in other quadrant constituted the test group 1 (Group II - SRP followed by application of Er, Cr: YSGG laser), and another site in different quadrant constituted the test group 2 (Group III - SRP followed by antimicrobial Photodynamic therapy using diode laser). The diode laser was operated at a peak power of 70 mW using a 0.6 mm diameter fiber-optic tip. Each site was irradiated with a power density of 28 mW/cm2, for 10 s, thus delivering a total energy of 16.72 J/cm2 per tooth. Whereas, the Er,Cr:YSGG laser's parameters were set to 1 W of power, 10% air, and 15% water. The same procedure was repeated at 1st, 2nd and 3rd week for both the laser therapies. Plaque index (PI), Gingival index (GI), Probing depth (PD,) and Clinical attachment level (CAL) were measured by a single examiner at baseline and 3 months follow up. Inter group analysis of the parameters were done using One-way ANOVA and pairwise comparison was carried out by Tukey's post hoc test. Intra group analysis was performed using Students's paired t test. Statistical significance was set to p < 0.05. RESULTS There were no significant differences between participants for clinical parameters at baseline. PI, GI PD, and CAL significantly improved at 3 months follow up compared to baseline in both the study groups (Group II - SRP + Er,Cr:YSGG, Group III - SRP + a-PDT) with P < 0.05. Adjunctive use of Er,Cr:YSGG laser with SRP showed better clinical outcomes than a-PDT with SRP. CONCLUSION Nonsurgical periodontal therapy of chronic periodontitis using Er, Cr: YSGG, and a-PDT as an adjunct to SRP was significantly more effective than SRP alone in reducing PD, CAL, GI, and PI at 3 months follow up. Adjunctive use of Er,Cr:YSGG laser with SRP showed better clinical outcomes than a-PDT with SRP. However, the long-term positive benefits of the laser therapies are yet unknown and more research with longer follow-ups are required.

Abstract
OBJECTIVES This study aimed to investigate the periodontal condition when patients became self-responsible for the continuation of periodontal care, after non-surgical periodontal therapy and 2 years of Supportive Periodontal Therapy (SPT). MATERIALS AND METHODS Fifty-seven patients completed a previous 2-year SPT study and were afterward advised to seek for dental assistance for maintenance care. After 4.2 ± 0.45 years of self-responsibility for periodontal care (SRPC), 27 patients could be re-examined of which 9 patients had followed the advice to turn to a dental professional for SPT care. Visible Plaque (VPI), Gingival Bleeding (GBI), Periodontal Probing Depth (PPD), Bleeding on probing (BOP), and Clinical Attachment Loss (CAL) were obtained from SPT study: before and after non-surgical treatment, and after 2 years of SPT. The same parameters were reassessed for the present study. General linear models for repeated measures were used for data analysis. RESULTS At the end of the SRPC period, mean GBI, BOP, and PPD values (43.5%, 55.7%, 2.76 mm, respectively) were back to pre-treatment, whereas VPI (64.3%) and CAL (3.76 mm) became significantly higher. The percentage of sites with PPD ≥5 mm as well as sites with CAL ≥4 or ≥5 mm also returned to pre-treatment values. However, the percentage of sites with PPD ≥4 mm was still significantly lower compared to pre-treatment values but higher than after 2 years of SPT. CONCLUSIONS Self-responsibility for the continuation of periodontal care after professional treatment should be avoided. CLINICAL RELEVANCE Clinicians and specialists must be conscious of making all efforts to maintain the patient's frequent recalls.

Abstract
BACKGROUND Supportive periodontal therapy (SPT) is the key for a stable periodontal health following active treatment. Likewise, implant maintenance is crucial following implant placement. This systematic review aimed to assess clinical outcomes, patients' perception, and cost-effectiveness of repeated periodontal therapy with air polishing devices (APDs) in comparison with hand instruments and/or power-driven instruments (conventional interventions) in SPT and implant maintenance. METHODS Electronic search for randomised controlled clinical trials with minimum 6 months follow-up for SPT and implant maintenance programme was conducted for data published from 01 January 2000 to 30 April 2020 using multiple databases and hand searching. Risk of bias was assessed using the Revised Cochrane Risk-of-Bias tool (RoB 2). RESULTS A total of 823 articles were screened. 4 SPT and 2 implant maintenance studies were eligible for inclusion. For SPT, repeated APDs interventions revealed no statistically significant difference when compared to the conventional interventions (weighted mean difference [WMD] 0.11 mm, p = 0.08). Likewise, no statistical difference was noted in terms of percentage of bleeding on probing (BOP) and clinical attachment level (CAL) gain. APDs were associated with lower pain score (based on Visual Analogue Scale) and higher patient acceptance in SPT studies. For implant maintenance, APDs resulted in reduction in PPD and percentage of BOP. However, CAL gain was comparable between the two groups. In terms of patient reported outcomes, no implant maintenance studies recorded any forms of patient reported outcomes. In addition, no studies reported on economic evaluation of APDs in both SPT and implant maintenance. CONCLUSION Within the limitations of this systematic review and meta-analysis, repeated subgingival debridement using APDs in SPT resulted in similar clinical outcomes but better patients' comfort when compared to the conventional interventions. For implant maintenance, there is limited evidence to show that repeated application of APDs leads to improved clinical outcomes when compared to conventional treatments.

Abstract
Background Clinical evidence indicates that there are various risk factors of tooth loss. However, the degree of this risk among other risk factors remains unclear. In this retrospective cohort study, the authors evaluated the hazard ratios of several risk factors for tooth loss. Methods Included patients had all been treated for dental disorders, were in the supportive phase of periodontal therapy by dental hygienists, and visited a Japanese dental office continually during a 10-year period. Periodontal parameters, tooth condition, and general status of all teeth (excluding third molars) at the initial visit and at least 10 years later were evaluated by using multiple classification analysis. Results The authors evaluated a total of 7584 teeth in 297 patients (average age: 45.3, mean follow-up time: 13.9 years) Non-vital pulp was the most significant predictor of tooth loss according to Cox hazards regression analysis (hazard ratio: 3.31). The 10-year survival rate was approximately 90% for teeth with non-vital pulp and 99% for teeth with vital pulp. Fracture was the most common reason for tooth loss. Conclusions Non-vital pulp had the most significant association with tooth loss among the parameters. Therefore, it is very important to minimize dental pulp extirpation.

Abstract
OBJECTIVES To predict patients' tooth loss during supportive periodontal therapy across four German university centers. METHODS Tooth loss in 897 patients in four centers (Kiel (KI) n = 391; Greifswald (GW) n = 282; Heidelberg (HD) n = 175; Frankfurt/Main (F) n = 49) during supportive periodontal therapy (SPT) was assessed. Our outcome was annualized tooth loss per patient. Multivariable linear regression models were built on data of 75 % of patients from one center and used for predictions on the remaining 25 % of this center and 100 % of data from the other three centers. The prediction error was assessed as root-mean-squared-error (RMSE), i.e., the deviation of predicted from actually lost teeth per patient and year. RESULTS Annualized tooth loss/patient differed significantly between centers (between median 0.00 (interquartile interval: 0.00, 0.17) in GW and 0.09 (0.00, 0.19) in F, p = 0.001). Age, smoking status and number of teeth before SPT were significantly associated with tooth loss (p < 0.03). Prediction within centers showed RMSE of 0.14-0.30, and cross-center RMSE was 0.15-0.31. Predictions were more accurate in F and KI than in HD and GW, while the center on which the model was trained had a less consistent impact. No model showed useful predictive values. CONCLUSION While covariates were significantly associated with tooth loss in linear regression models, a clinically useful prediction was not possible with any of the models and generalizability was not given. Predictions were more accurate for certain centers. CLINICAL RELEVANCE Association should not be confused with predictive value: Despite significant associations of covariates with tooth loss, none of our models was useful for prediction. Usually, model accuracy was even lower when tested across centers, indicating low generalizability.

Abstract
OBJECTIVES To evaluate yearly tooth loss rate (TLR) in periodontitis patients with different periodontal risk levels who had complied or not complied with supportive periodontal care (SPC). MATERIALS AND METHODS Data from 168 periodontitis patients enrolled in a SPC program based on a 3-month suggested recall interval for at least 3.5 years were analyzed. For patients with a mean recall interval within 2-4 months ("compliers") or > 4 months ("non-compliers") with different PerioRisk levels (Trombelli et al. 2009), TLR (irrespective of the cause for tooth loss) was calculated. TLR values were considered in relation to meaningful TLR benchmarks from the literature for periodontitis patients either under SPC (0.15 teeth/year; positive benchmark) or irregularly complying with SPC (0.36 teeth/year; negative benchmark). RESULTS In both compliers and non-compliers, TLR was significantly below or similar to the positive benchmark in PerioRisk level 3 (0.08 and 0.03 teeth/year, respectively) and PerioRisk level 4 (0.12 and 0.18 teeth/year, respectively). Although marked and clinically relevant in non-compliers, the difference between TLR of compliers (0.32 teeth/year) and non-compliers (0.52 teeth/year) with PerioRisk level 5 and the negative benchmark was not significant. CONCLUSION A SPC protocol based on a 3- to 6-month recall interval may effectively limit long-term tooth loss in periodontitis patients with PerioRisk levels 3 and 4. A fully complied 3-month SPC protocol seems ineffective when applied to PerioRisk level 5 patients. CLINICAL RELEVANCE PerioRisk seems to represent a valid tool to inform the SPC recall interval as well as the intensity of active treatment prior to SPC enrollment.

Abstract
BACKGROUND Recent data from preclinical studies and case series suggest that transgingival irradiation with diode lasers may represent a novel modality for antimicrobial photodynamic therapy (aPDT). However, at present, there is lack of data from controlled clinical studies on the use of transgingival antimicrobial photodynamic therapy (tg-aPDT) in the treatment of periodontitis. OBJECTIVE To evaluate the clinical effects of tg-aPDT used in conjunction with nonsurgical mechanical instrumentation during supportive periodontal therapy (SPT). MATERIALS AND METHODS Forty stage II and III periodontitis patients enrolled in SPT were randomly assigned to two groups of equal size. At baseline, study sites had to show sites with pocket probing depth (PPD) of ≥ 5 mm and Bleeding on Probing (BOP). Full mouth and site-specific Plaque-Index scores (PI), BOP, PPD, and Clinical Attachment Level (CAL) were recorded at baseline (BL), three months (3 M), and 6 months (6 M), respectively. The primary outcome variable was the change in the number of sites with BOP. Treatment was performed under local anaesthesia after random allocation to one of the following groups 1) Subgingival scaling and root planing (SRP) + tg-aPDT (test) or 2) SRP alone (control). RESULTS Thirty-nine patients completed the study. Full mouth PI and BOP improved over six month, however without statistically significant difference between the groups. At 6 M, BOP-levels were statistically significantly lower in test sites (25.0 %) compared to the control sites (65.0 %), (p < 0.025). PPD improved in both groups with comparable mean values at 3 M (PPD test: 5.21 ± 0.92 mm; PPD control: 4.45 ± 1.36 mm) and 6 M (PPD test: 5.11 ± 1.10 mm; PPD control: 4.35 ± 1.14 mm). Additionally, CAL slightly improved in both groups with comparable mean values at 3 M (CAL test: 6.79 ± 1.72 mm; CAL control: 5.30 ± 2.43 mm) and 6 M (CAL test: 6.26 ± 1.70 mm; CAL control: 5.50 ± 2.33 mm). CONCLUSIONS Within its limits, the present results appear to indicate that the use of tg-aPDT adjunctive to SRP may represent a new modality for controlling inflammation and further bleeding in residual periodontal pockets.

Abstract
Objectives The absence of bleeding on probing (BOP) is a good predictor of disease stability. This study investigated whether detection of hemoglobin (Hb) in gingival crevicular fluid (GCF) indicates minute signs of periodontal disease, even in BOP (−) cases. Materials and methods GCF was collected from gingival sulci of 152 sound maxillary and mandibular teeth from 76 patients who had entered supportive periodontal therapy (SPT) using the split-mouth design. As clinical parameters, plaque index, GCF amount, gingival index, probing depth (PD), clinical attachment level, BOP, and alveolar bone resorption ratio were then recorded. As biochemical parameters, Hb amount, alkaline phosphatase (ALP) activity, and protein amount in GCF were measured. Periodontal conditions of diseased sites (PD ≥ 4 mm, BOP (+)) and healthy sites (PD ≤ 4 mm, BOP (−)) were further classified into two groups using the Hb cutoff value determined by PD and BOP and analyzed. Results Despite being healthy, ALP activity and protein amount in sulci of the group with Hb level greater than the cutoff value were significantly higher than those in the group with Hb level less than the cutoff value (P < 0.01). Conclusions This study indicates that Hb examination is a promising candidate marker of pre-symptomatic periodontal disease because Hb presence in GCF suggests slight tissue damage, even in healthy sites defined as BOP (−). Clinical relevance Hb examination of GCF is a powerful diagnostic tool for pre-symptomatic diagnosis of periodontal disease.

Abstract
We report a case of generalized chronic periodontitis requiring periodontal treatment including regenerative therapy. The patient was a 57-year-old who man presented with the chief complaint of gingival swelling and mobile teeth in the right maxillary molar region. An initial examination revealed 55.3% of sites with a probing depth of ≥4 mm and 24.0% with bleeding on probing. Radiographic examination revealed vertical bone resorption in teeth #16, 17, 25, 26, 37, and 45; horizontal resorption was also noted in other areas. Based on a clinical diagnosis of severe chronic periodontitis, initial periodontal therapy consisting of plaque control, scaling and root planing, and caries treatment was performed. Both #16 and 17 were extracted due to bone resorption extending as far as the root apex. A removable partial denture was placed for #16 and 17, and a provisional restoration for #25 and 26. Surgical periodontal therapy was subsequently performed at selected sites. Periodontal regenerative therapy using enamel matrix derivative (EMD) with autogenous bone graft (ABG) was performed on #25 and 26. Other sites with residual periodontal pockets (#31, 32, 33, 36, 37, and 41) were treated by open flap debridement. Following reevaluation, full metal crowns (#25 and 26) and the removable partial denture were placed for #16, 17, 46, and 47. After further reevaluation, the patient was placed on supportive periodontal therapy (SPT). Periodontal regenerative therapy using EMD with ABG resulted in improvement in vertical bone resorption. This improvement has been adequately maintained over an 18-month period. The patient has continued to have some minor problems in occlusal contact and guidance following active therapy, however. Therefore, additional care will be necessary to maintain stable periodontal conditions during SPT.

Abstract
Here, we report periodontal treatment including regenerative therapy in a patient with generalized chronic periodontitis. The patient was a 53-year-old woman who presented with the chief complaint of gingival swelling and tooth mobility in the right maxillary molar region. An initial examination revealed 36% of sites with a probing depth of ≥4 mm and 15.5% with bleeding on probing. Radiographic examination revealed vertical bone resorption in #15, 24, 27, 34, 37, 45, and 47. Horizontal resorption was noted in other regions. The clinical diagnosis was moderate chronic periodontitis. Initial periodontal therapy consisted of plaque control, scaling, and root planing together with treatment for caries. Occlusal adjustment of premature contact sites was performed after suppression of inflammation. Periodontal regenerative therapy using enamel matrix derivative was performed on #15, 24, 34, 45, and 47. Other sites with residual periodontal pockets were treated by open flap debridement. Tooth #27 was extracted due to a bone defect exceeding the root apex; #37 was extracted due to frequent acute symptoms following periodontal surgery. Following re-evaluation, the patient was placed on supportive periodontal therapy. Periodontal regenerative therapy improved vertical bone resorption. This improvement has been adequately maintained over a 3 years 6 months period. Additional care is necessary, however, to further improve the patient's oral health-related quality of life during supportive periodontal therapy.

Abstract
Background Supportive periodontal therapy (SPT) must take individual patient risk factors into account. We conducted a multicenter joint retrospective cohort study to investigate the value of modified periodontal risk assessment (MPRA) and therapy-resistant periodontitis (TRP) assessment as predictive factors for tooth loss due to periodontal disease in patients with severe periodontitis during SPT. Methods The subjects were 82 patients from 11 dental institutions who were diagnosed with severe periodontitis and continued SPT for at least 1 year (mean follow-up = 4.9 years) between 1981 and 2008. The outcome was tooth loss due to periodontal disease during SPT. The Cox proportional hazards model was used to analyze sex, age, diabetes status, smoking history, number of periodontal pockets measuring ≥6 mm, rate of bleeding on probing, bone loss/age ratio, number of teeth lost, MPRA, and TRP assessment as explanatory variables. Results Univariate analysis showed that loss of ≥8 teeth by the start of SPT [hazard ratio (HR) 2.86], MPRA score indicating moderate risk (HR 8.73) or high risk (HR 11.04), and TRP assessment as poor responsiveness to treatment (HR 2.79) were significantly associated with tooth loss (p < 0.05). In a model in which the explanatory variables of an association that was statistically significant were added simultaneously, the HR for poor responsiveness to treatment and ≥8 teeth lost was significant at 20.17 compared with patients whose TRP assessment indicated that they responded favorably to treatment and who had lost <8 teeth by the start of SPT. Conclusion MPRA and TRP assessment may be useful predictive factors for tooth loss due to periodontal disease during SPT in Japanese patients with severe periodontitis. Additionally, considering the number of teeth lost by the start of SPT in TRP assessment may improve its predictive accuracy.

Abstract
Purpose The aim of this retrospective cross-sectional study was to evaluate whether salivary findings of active matrix-metalloproteinase 8 (aMMP-8) chairside (point of care; POC) tests were associated with periodontal risk assessment parameters in patients receiving supportive periodontal therapy (SPT). Methods A total of 125 patients receiving regular SPT were included, and their records were examined. The following inclusion criteria were used: a diagnosis of chronic periodontitis, at least 1 non-surgical periodontal treatment (scaling and root planning) with following regular SPT (minimum once a year), at least 6 remaining teeth, and clinical and aMMP-8 findings that were obtained at the same appointment. In addition to anamnestic factors (e.g., smoking and diabetes), oral hygiene indices (modified sulcus bleeding index [mSBI] and approximal plaque index), periodontal probing depth simultaneously with bleeding on probing, and dental findings (number of decayed, missing, and filled teeth) were recorded. Salivary aMMP-8 levels were tested using a commercial POC test system (Periomarker, Hager & Werken, Duisburg, Germany). Statistical analysis was performed using the t-test, Mann-Whitney U test, Fisher's exact test, and χ2 test, as appropriate (P<0.05). Results Only the mSBI was significantly associated with positive salivary aMMP-8 findings (aMMP-8 positive: 27.8%±20.9% vs. aMMP-8 negative: 18.0%±14.5%; P=0.017). No significant associations were found between aMMP-8 and smoking, diabetes, periodontal parameters, or parameters related to the maintenance interval (P>0.05). Conclusions Salivary aMMP-8 chairside findings were not associated with common parameters used for periodontal risk assessment in patients receiving SPT. The diagnostic benefit of POC salivary aMMP-8 testing in risk assessment and maintenance interval adjustment during SPT remains unclear.

Abstract
Objective This study aimed to evaluate clinically the effect of a novel dentifrice containing three kinds of bactericidal ingredients on periodontal disease. Results This was a single-arm, prospective clinical study that enrolled patients with periodontitis undergoing supportive periodontal therapy. Periodontal examination, microbiological testing of saliva samples, and evaluation of inflammatory markers (IL-1β, IL-6, IL-8, TNF-α) in gingival crevicular fluid were performed. After 4 weeks of the use of test dentifrice, these parameters were re-evaluated. The use of dentifrice was also subjectively evaluated by clinicians and participants. Among 30 participants, there were significant improvements in the periodontal and microbiological parameters, and the level of interleukin-1β in the gingival crevicular fluid, following the use of the test dentifrice. In clinicians’ subjective evaluation of the overall usefulness of the dentifrice, ‘mild’ and ‘moderate’ improvement accounted for 83% of the total responses. In the participants’ subjective evaluation, the majority indicated their experience of the use as favorable. Within the limitations of this study, it is suggested that the progression of periodontal disease during the supportive periodontal therapy can be prevented by the use of the test dentifrice.

Abstract
A 60-year-old woman presented with the chief complaint of mobility of tooth #16. Gingival swelling and calculus were observed. Clinical examination revealed that 49.4% of sites had a probing depth (PD) of ≥4 mm and 72% of sites bleeding on probing. Radiographic examination revealed vertical bone resorption in #35 and horizontal resorption in other regions. Periapical region radiolucency on #16 and 27 suggested a perio-endo lesion. The clinical diagnosis was severe chronic periodontitis. Initial periodontal therapy mainly comprised the following: oral hygiene instruction; quadrant scaling and root planing (SRP); extraction of #16, 27, and 31; and placement of provisional restorations. Open flap debridement was performed for teeth with a PD ≥4 mm. Bone defects exceeding the root apex were found in #17, 41, 42, and 45 intraoperatively. Teeth #41, 42, and 45 were extracted. After confirming the stability of the periodontal tissue, final prostheses were placed on #14-17, 13-22, 35-37, 33-43, 44-46, and 47. Following reevaluation, the patient was placed on supportive periodontal therapy (SPT). After 6 years, the patient experienced dull pain in and pus discharge from #17. Repeated SRP yielded no improvement, so the tooth was extracted and a removable partial denture placed on #16 and 17. Nine years have passed since the start of SPT and the level of plaque control has remained adequate and periodontal condition stable.

Abstract
BACKGROUND The study aims to compare the effects of adjunctive photodynamic therapy (PDT) with scaling and root debridement alone on periodontal parameters and inflammatory cytokines in residual pockets of patients undergoing maintenance therapy. METHODS 27 subjects, each with at least 2 residual pockets ≥5mm, were recruited for this randomized, split-mouth controlled trial, providing total of 72 sites. Probing pocket depth (PPD), recession, clinical attachment loss (CAL), plaque and bleeding on probing of all sites were examined at baseline, 3 and 6 months. Gingival crevicular fluids (GCFs) were collected to determine levels of IL-1β, IL-6, IL-8, TNF-α and MMP-8 via enzyme-linked immunosorbent assay. At baseline, all sites received subgingival instrumentation and polishing. In addition, test sites received a single application of PDT using Fotosan® with toluidine blue O solution photosensitizer. At 3 and 6 months, site level analysis was performed for changes in clinical parameters and cytokine level. RESULTS Based on mixed model analysis, at 3 months, test sites showed significant reduction in CAL (p=0.016) and PPD (p=0.027) (from 6.14±0.28mm to 5.49±0.20mm and 5.42±0.16mm to 4.65±0.18mm respectively) compared to control sites (from 6.32±0.24mm to 6.08±0.17mm and 5.32±0.13mm to 5.15±0.15mm respectively). At 6 months, these differences were no longer significant (p=0.510). Adjunctive PDT did not offer additional reduction in levels of GCF cytokines. CONCLUSIONS A single application of PDT to residual pockets provided a modest improvement of CAL and PPD over 3 months. Application of adjunctive PDT may lead to faster resolution of residual pockets and may be recommended for periodontal patients with slower healing capacity.

Abstract
OBJECTIVES The ultrasonic NO PAIN technology (Electro Medical Systems, Nyon, CH) promises minimal pain during debridement due to linear oscillating action combined with a sinusoidal power output and feedback control. The aim of the present study was to measure pain perception on a visual analogue scale (VAS) during supportive periodontal therapy including debridement of hypersensitive teeth. Two ultrasonic scalers were used, one with and one without NO PAIN technology. MATERIAL AND METHODS In a randomized-controlled clinical study with split-mouth design, 100 hypersensitive teeth matched for air blast hypersensitivity were either treated with the ultrasonic device Piezon Master 700 or the Mini Piezon (both EMS, Nyon, CH). Pain perception during debridement was assessed by a VAS (range 0-10). RESULTS The average VAS for the test device Piezon Master 700 with NO PAIN technology was 3.16 ± 2.10, and for the control device Mini Piezon without NO PAIN technology 3.40 ± 2.59 (p = 0.490). Placing an arbitrary threshold at the VAS score of 3 for significant pain experience, 60 % of the subjects experienced no significant pain with either instrument. CONCLUSION No statistically significant difference in perceived pain between the instruments used was found. CLINICAL RELEVANCE Both ultrasonic devices showed very small pain intensities during debridement of highly hypersensitive teeth and can therefore be recommended for supportive periodontal therapy.

Abstract
We report a case of severe chronic periodontitis treated and longitudinally maintained by a periodontist and dental hygienists. The patient was a 45-year-old woman who presented with the chief complaint of gingival bleeding and tooth mobility. An initial examination revealed generalized gingival inflammation and subgingival calculus in the premolar and molar regions. Premature contact was observed in #14 and 45. Clinical examination revealed 42% of sites with a probing depth (PD) of ≥4 mm and 44% of sites with bleeding on probing. Radiographic examination revealed vertical bone resorption in #35, 36, and 45, and horizontal bone resorption in other regions. Based on a clinical diagnosis of severe chronic periodontitis, initial periodontal therapy consisting of plaque control, scaling and root planing, and removal of an ill-fitting prosthesis was performed. Following suppression of inflammation, occlusal adjustment of premature contact sites was performed. Open flap debridement was performed for teeth with a PD of ≥5 mm. After confirming the stability of the periodontal tissue, final prostheses were placed on #16, 35-37, and 46. Following re-evaluation, the patient was placed on supportive periodontal therapy. It has been 11 years since the patient's first visit, and the periodontal conditions have remained stable. Meticulous periodontal care maintained over a number of years by a periodontist and dental hygienist have yielded a clinically favorable outcome.

Abstract
OBJECTIVES A systematic review of the literature was undertaken to assess the evidence to support a specific time interval between periodontal maintenance (PM) visits. METHODS Relevant articles were identified through searches in MEDLINE, EMBASE and PubMed using specific search terms, until April, 2014, resulting in 1095 abstracts and/or titles with possible relevance. Critical Appraisal Skills Programme (CASP) guidelines were used to evaluate the strength of studies and synthesize findings. If mean recall interval was not reported for study groups, authors were contacted to attempt to retrieve this information. RESULTS Eight cohort studies met the inclusion criteria. No randomized control trials were found. All included studies assessed the effect of PM recall intervals in terms of compliance with a recommended regimen (3-6 months) as a primary outcome. Shorter PM intervals (3-6 months) favored more teeth retention but also statistically insignificant differences between RC and IC/EC, or converse findings are also found. In the 2 studies reporting mean recall interval in groups, significant tooth loss differences were noted as the interval neared the 12 month limit. CONCLUSIONS Evidence for a specific recall interval (e.g. every 3 months) for all patients following periodontal therapy is weak. Further studies, such as RCTs or large electronic database evaluations would be appropriate. The merits of risk-based recommendations over fixed recall interval regimens should be explored.
