Comparative Study
BACKGROUND AND OBJECTIVES
Depressed chemotactic activity of polymorphoneutrophil (PMN) and monocyte (MN) appears to be one of the significant risk factors in the development of periodontal disease. Although bacteria are the primary etiologic factor in periodontal disease, the patient's host response is a determinant of disease susceptibility. Depressed chemotaxis of PMN and MN could lead to periodontal destruction by altering the host response i.e. impairment of the normal host response in neutralizing infection and alterations that result in destruction of the surrounding periodontal tissues.
MATERIALS AND METHODS
Thirty patients (10 healthy subjects, 10 chronic periodontitis, and 10 with aggressive periodontitis) participated in this study. Clinical parameters like plaque index, gingival index, probing pocket depth, and radiographic assessment were done. The peripheral blood PMNs and MNs were isolated from the patient and the chemotactic response was studied. Statistical analysis was performed using post-hoc Newman-Keul range test.
RESULTS
PMN and MN chemotaxis was found to be statistically significant (P<0.05) at baseline and three months after periodontal therapy in chronic and aggressive periodontitis group compared to healthy subjects. However on comparison between chronic and aggressive periodontitis group statistical significance was not found (P>0.05).Comparision between chronic periodontitis, aggressive periodontitis with healthy subjects, PMN and MN chemotaxis showed statistical significance (P<0.05) at baseline and three months after periodontal therapy, Whereas statistically there was no difference when chronic periodontitis was compared with aggressive periodontitis.
INTERPRETATION AND CONCLUSION
Depressed chemotaxis of PMN and MN results in increased periodontal destruction. In this study, depressed PMN and MN chemotaxis is seen in both aggressive periodontitis group and chronic periodontitis group and the response was altered although to a lesser degree after periodontal therapy in both groups indicating that effect of treatment does exist.

OBJECTIVES
8-Hydroxideoxyguanosine (8-OHdG) is a marker of oxidative stress, and Forkhead Box-O1 (FOXO1) is a transcription factor and signaling integrator in cell and tissue homeostasis. This study aims to determine FOXO1 and 8-OHdG levels in serum and saliva samples of periodontitis patients and to evaluate their relationship with clinical periodontal parameters.
MATERIALS AND METHODS
Twenty healthy individuals, twenty generalized Stage III Grade B periodontitis patients, and nineteen generalized Stage III Grade C periodontitis patients were included in the study. Clinical periodontal parameters (plaque index (PI), probing depth (PD), bleeding on probing (BOP), and clinical attachment level (CAL)) were recorded. Salivary and serum 8-OHdG and FOX-O1 levels were analyzed by enzyme-linked immunosorbent assay (ELISA).
RESULTS
Clinical periodontal parameters showed a statistically significant increase in periodontitis groups compared to the control group (p < 0.05). 8-OHdG salivary levels were significantly higher in both periodontitis groups compared to the control group. The salivary FOXO1 levels were significantly lower in both periodontitis groups compared to the control group. Salivary FOXO1 level had a low-grade negative correlation with BOP and salivary 8-OHdG level.
CONCLUSIONS
While reactive oxygen species increase in periodontal inflammation, low expression of FOXO1, an important transcription factor for antioxidant enzymes, supports that this molecule plays a vital role in tissue destruction, and FOXO1 can be seen as a potential immune modulator.
CLINICAL RELEVANCE
The role of FOXO1 in supporting antioxidant defense may suggest that FOXO1 is a candidate target for periodontitis treatment.

BACKGROUND
Full-mouth scaling and root planing combined with azithromycin is clinically and bacteriologically effective for the treatment of chronic periodontitis. This study aimed to investigate the clinical and bacteriological effects of this combination treatment in patients with peri-implantitis.
METHODS
Twenty adult patients with both chronic periodontitis and peri-implantitis were randomly divided into two groups (10: test, 10: control). All patients underwent full-mouth scaling and root planing but the test group received azithromycin for 3 days before the procedure. The probing depth, bleeding on probing, and the gingival index were assessed clinically. Bacterial samples were obtained before treatment at 1 week and 1, 3, 6, 9 and 12 months after treatment. Quantitative and qualitative analyses were performed using the polymerase chain reaction Invader method.
RESULTS
All clinical parameters showed better improvement in both periodontitis and peri-implantitis in the test group. Periodontal bacteria were more effectively reduced in the test group, but gradually increased around implants 6 months after treatment and natural teeth 9 months after treatment.
CONCLUSIONS
Full-mouth scaling and root planing combined with azithromycin was temporarily useful for the treatment of peri-implantitis. Clinical improvements were maintained for about 9 months but periodontal bacteria increased again 6 months after treatment.

ackground and bjective: The current study was performed to evaluate the prevalence of periodontitis and to examine the association between reduced pulmonary function and periodontitis using Sixth Korea National Health and Nutrition Examination Survey (KNHANES) in 2014. : A cross-sectional evaluation was conducted to estimate the prevalence of periodontitis and to examine the association between periodontitis and reduced pulmonary function while adjusting for sociodemographic characteristics and current smoking status in survey participants between 40 and 79 years old. The presence of periodontitis was evaluated by community periodontal index defined by the World Health Organization, and the assessments of reduced pulmonary function data were made as "normal," "restrictive impairment," or "obstructive impairment." : A total of 4004 survey participants representing 25.4 million Koreans were included in the study. Overall, 41.1% of the study population were determined to have periodontitis, and 22.1% had reduced pulmonary function; 7.9% and 14.2% had restrictive- and obstructive- pulmonary impairments, respectively. Age, male gender, and current smoking status were positive predictors for periodontitis. Insurance coverage by workplace and higher education were protective factors against periodontitis. The association between periodontitis and restrictive impairment (adjusted odds ratio (OR) = 1.059, 95% CI 0.729-1.540) or obstructive impairment (adjusted OR = 1.140, 95% CI 0.849-1.530) was not significant. : For Koreans, 40-79 years old, age, smoking status, gender, education, and insurance coverage were significant predictors of periodontitis. The prevalence of periodontitis was not significantly associated with reduced pulmonary function. To better understand the relationship between periodontitis and reduced pulmonary function, well-designed and larger scale epidemiologic studies are needed.

Review
BACKGROUND
The use of herbal products in oral cavity has shown an increased popularity and potential benefits due to their additional anti-inflammatory and antioxidant properties as well as the lack of side effects related to their use.
OBJECTIVE
To assess the clinical effectiveness of herbal dental products (mouthwash, dentifrice, gel) when compared to conventional products or placebo in periodontitis patients.
MATERIAL AND METHODS
A systematic review with 22 studies was carried out using MEDLINE/Pubmed, EMBASE and Web of Science databases in addition to hand searches. Randomized and non-randomized clinical trials that evaluated the effect of any herbal dental product and compared it with conventional products or placebo in periodontitis patients and published up to March 2022, were screened.
RESULTS
Herbal products used as adjuncts to scaling and root planing (SRP) or supragingival debridement (SPD) led to superior clinical outcomes than placebo or no adjuncts (8 studies). In conjunction with SRP, these products showed comparable outcomes with chlorhexidine (6 studies) or better (4 studies). When used as adjuncts to SPD, herbal oral care products demonstrated comparable outcomes with chlorhexidine and conventional products (4 studies).
CONCLUSIONS
Within the limitations of this systematic review, herbal oral care products may play a key role in the management of periodontal disease. Further well-designed studies are needed to establish their efficacy.

Evaluation of efficacy of subgingival administration of 1% chlorhexidine gel as an adjunct to scaling and root planing in the treatment of chronic periodontitis - A clinical and microbiological study.
AIM
The aim of the present study was to evaluate the clinical and microbiological effects of subgingival administration of 1% chlorhexidine gel (Chlorhexamed® 1% gel) in patients with chronic periodontitis.
SETTINGS AND DESIGN
The study was done in a parallel-arm design with a total of 30 patients with 60 sites suffering from chronic periodontitis. The patients were divided into control and experimental groups.
MATERIALS AND METHODS
The clinical parameters recorded were plaque index, gingival index, modified sulcular bleeding index, probing pocket depth and relative attachment level at baseline, 1 month and 3 month. Microbiological colony-forming units were assessed for Porphyromonas gingivalis, Fusobacterium nucleatum and Tannerella forsythia at baseline, 1 week, 1 month and 3 months. The control group received scaling and root planing (SRP) after baseline evaluation; however, the experimental group received the application of Chlorhexamed® gel within 48 hours after SRP. Then, the values obtained were subjected to statistical analysis.
RESULTS
Both groups showed significant improvement from the baseline to 3 months in all clinical and microbiological parameters. The experimental group showed better improvement in all parameters.
CONCLUSION
The use of Chlorhexamed® gel has proven to be an efficacious adjunct with SRP in the treatment of chronic periodontitis.

OBJECTIVES
Changes in periodontal referral patterns over time have been reported from the United States and Australia. To date, comparable studies have not been published from Europe. The objectives of the present study were to examine changes in periodontal referral patterns in Norway in 2003 versus 2018 and to compare these with trends observed in the United States and Australia using universal criteria for grading of periodontal severity.
MATERIALS AND METHODS
A retrospective analysis of 369 charts from four Norwegian periodontics clinics was completed. Data on year of referral, gender, age, tobacco smoking, periodontal status and missing teeth at initial examination, teeth planned for extraction, and periodontal case type were collected using a survey format; case type I, II, III, and IV representing increasing severity of periodontitis, case type V representing referral for other periodontal conditions (peri-implantitis, refractory periodontitis, etc.). Chi-square, t-tests, and negative binomial regression were used for the statistical analysis.
RESULTS
Compared with 2003, the 2018 data showed an increase in mean age at referral (p < 0.05), overall distribution of case type III and V (p = 0.047), and number of missing teeth (p = 0.001). Further, a decrease in prevalence of smokers (p < 0.05), but no change in number of teeth planned for extraction (p = 0.104), were observed.
CONCLUSIONS
During a period of 15 years, changes in periodontal referral patterns in Norway are similar to those in the United States and Australia. The adoption of a guideline-based referral practice might be beneficial for both the dental profession and patients.

The aim of the present study was to compare periodontal conditions between intensive care unit (ICU) in-patients and non-ICU patients through clinical and microbiological periodontal parameters. This case-control study included 88 individuals hospitalized in ICU and 176 non-hospitalized controls. All individuals underwent a complete periodontal examination and microbiological sampling. The total bacterial load and counts of Porphyromonas gingivalis, Treponema denticola and Aggregatibacter actinomycetemcomitans were evaluated using qPCR. Data were analyzed through the Chi-square, Fisher exact, and t-Student tests, and the Spearman correlation, as appropriate. The prevalence of periodontitis was 39.7% among controls and 59.0% among ICU in-patients (OR=2.18; p=0.002). ICU in-patients had a significantly higher occurrence of cardiovascular disease (p=0.002; OR=2.20) and history of periodontal disease (p=0.031; OR=1.92) than controls. Bacterial counts of A. actinomycetemcomitans, T. denticola and P. gingivalis were significantly higher in ICU in-patients with periodontitis than in controls. The correlation between periodontal parameters and microbiological findings among cases and controls showed a significant and positive correlation between: total bacteria load and % of sites with probing depth (PD) ≥ 4 mm (cases: r=0.22 and controls: r=0.13) and P. gingivalis and % sites with bleeding on probing (BOP) (cases: r=0.22 and controls: r=0.23). Thus, ICU in-patients presented a higher prevalence of periodontitis and worse periodontal condition (higher mean plaque index, BOP, clinical attachment level ≥3 mm, and sites with PD 4 to 6 mm).

Periodontitis and chronic kidney disease are both chronic inflammatory diseases and share some common risk factors. This 3-month pilot study aimed to clarify whether non-surgical periodontal therapy is beneficial in clinical, biochemical, and microbiological conditions in patients with periodontitis and kidney failure. Kidney failure patients with moderate to severe periodontitis were recruited from two hospitals. Treatment group received non-surgical periodontal therapy, and control group received oral hygiene instruction only. Outcome assessments were conducted 1 and 3 months after treatment. Non-parametric tests were used to analyze the patient-level data. Periodontal site-level assessments were analyzed by Student -test and paired -test. Statistical significance was set at -value < 0.05. A total of 11 subjects completed the study. There was no significant difference between groups in all-cause mortality, cardiovascular events, infection events, systemic parameters, and serum biomarkers. Comparing to control group, clinical periodontal parameters, gingival crevicular fluid interleukin-1β (IL-1β) level and periodontal pathogens showed significant improvement in the treatment group. Non-surgical periodontal treatment did not change systemic outcomes in kidney failure patients, but changed the local micro-environment.

Meta-Analysis
BACKGROUND
Periodontitis is a common and chronic inflammatory disease characterized by irreversible destruction of the tooth surrounding tissues, especially intrabony defects, which eventually lead to tooth loss. In recent years, stem cell-based therapy for periodontitis has been gradually applied to the clinic, but whether stem cell-based therapy plays a positive role in periodontal regeneration is unclear at present.
METHODS
The clinical studies related to the evaluation of mesenchymal stem cells for periodontal regeneration in PubMed, Cochrane Central Register of Controlled trials (CENTRAL), Web of Science (WOS), Embase, Scopus, Wanfang and China national knowledge infrastructure (CNKI) databases were searched in June 2023. The inclusion criteria required the studies to compare the efficacy of stem cell-based therapy with stem cell free therapy for the treatment periodontitis, and to have a follow-up for at least six months. Two evaluators searched, screened, and assessed the quality and the risk of bias in the included studies independently. Review Manager 5.4 software was used to perform the meta-analysis, and GRADEpro GDT was used to evaluate the level of the evidence.
RESULTS
Five randomized controlled trials (RCTs) including 118 patients were analyzed. The results of this meta-analysis demonstrated that stem cell-based therapy showed better therapeutic effects on clinical attachment level (CAL) (MD = - 1.18, 95% CI = - 1.55, - 0.80, P < 0.00001), pocket probing depth (PPD) (MD = - 0.75, 95% CI = - 1.35, - 0.14, P = 0.020), and linear distance from bone crest to bottom of defect (BC-BD)( MD = - 0.95, 95% CI = - 1.67, - 0.23, P = 0.010) compared with cell-free group. However, stem cell-based therapy presented insignificant effects on gingival recession (P = 0.14), linear distance from cementoenamel junction to bottom of defect (P = 0.05).
CONCLUSION
The results demonstrate that stem cell-based therapy may be beneficial for CAL, PPD and BC-BD. Due to the limited number of studies included, the strength of the results in this analysis was affected to a certain extent. The high-quality RCTs with large sample size, multi-blind, multi-centric are still required, and the methodological and normative clinical study protocol should be established and executed in the future.
