Cost-effectiveness and cost-utility analyses of three different gargles in the treatment of chronic periodontitis.

OBJECTIVE: This study aimed to investigate the economics of three different gargles in the treatment of chronic periodontitis. METHODS: A total of 108 patients with periodontitis received one of the following three gargles: xipayi, compound chlorhexidine, or Kangfuxin gargle. The basic information of the patients, the costs of the gargles, the periodontal indexes before and after treatment, and the scores of the 3-level version of the EuroQol Five Dimensions Questionnaire were collected. The cost-effectiveness and cost-utility of the various gargles were determined. RESULTS: The cost-effectiveness ratios (CER) of the three groups after treatment were 1828.75, 1573.34, and 1876.92 RMB, respectively. The utility values before treatment were 0.92, 0.90, and 0.91, respectively, and the utility values after treatment were 0.98, 0.98, and 0.97, respectively. The cost-utility ratios (CURs) were 213.43, 195.61, and 301.53 RMB, respectively. CONCLUSIONS: For each increase in effective rate and quality-adjusted life years, the treatment cost of periodontitis patients was lower than the gross domestic product per capita of Jiangsu Province, indicating that the treatment cost is completely worth it. The CER and CUR results were the same, and the compound chlorhexidine group was the lowest, demonstrating that when the same therapeutic effect was achieved, it cost the least.

Assessment of the Antibacterial Effect of Vitamin D3 against Red Complex Periodontal Pathogens: A Microbiological Assay.

AIM: The study aims is to evaluate the antibacterial effect of vitamin D3 against the red complex bacteria, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia in chronic periodontitis patients. MATERIALS AND METHODS: The study comprised 98 participants with chronic periodontitis. All clinical parameters including plaque index (PI), gingival bleeding index (GBI), probing pocket depth (PPD), clinical attachment level (CAL), and a microbiological assay of P. gingivalis, T. denticola, T. forsythia were assessed at the baseline. All study participants who underwent scaling and root planning were divided into two groups, A and B, each with 49 patients and only group B patients were advised to take vitamin D supplementation of 60,000 IU granules, once daily for 2 months. All the patients of both the groups were recalled at the end of 2nd month and all the clinical and microbiological parameters were reassessed. RESULTS: After two months, there was a reduction in all the clinical markers in both groups, but the group B patients showed more improvement following non-surgical treatment vitamin D intake. There was also a statistical reduction in P. gingivalis, T. denticola, and T. forsythia following administration of vitamin D in group B patients compared to group A. CONCLUSION: These discoveries proposed that vitamin D has a superb antimicrobial impact against red complex periodontal microbes and might be considered a promising compound in the counteraction of periodontal disease. CLINICAL SIGNIFICANCE: Vitamin D is considered to possess anti-inflammatory and antimicrobial activity, which may help to delay the progression of periodontitis. So, vitamin D3 can be used as a potential supplement that could be employed to stop the advancement of periodontal disease. How to cite this article: Govindharajulu R, Syed NK, Sukumaran B, et al.

Assessment of clinical efficacy of 445 nm Diode laser as an adjunct to Kirkland flap surgery in the management of periodontitis - a split mouth randomized clinical trial.

Aim of this study is to assess the clinical efficacy of 445 nm Diode laser as an adjunct to Kirkland flap surgery in management of periodontitis. Type of study is a Split mouth clinical trial in which a total of 13 patients were recruited based on specific inclusion and exclusion criteria. In each participant, random allocation of selected sites into test and control in contralateral quadrants was done. Clinical parameters such as probing depth and clinical attachment loss was measured in control and test sites using occlusal stents. Flap surgery was carried out 6 weeks after phase I therapy and the selected contralateral sites with a probing depth of > 5mm were subjected to surgical therapy. In a test quadrant, 445 nm diode laser with a power of 0.8 W, CW mode, 320 µm fiber, in non-contact mode was used as an adjunct to flap surgery. Primary outcome variable assessed was change in PPD between baseline, pre-operative, 1-, 3- and 6-months post-surgery. Secondary outcomes variables assessed were Clinical attachment loss at baseline, pre-operative, 1, 3 and 6 months, visual analog scale at days 3 and 7 and patient satisfaction index at day 7 post surgery. Surgery for the second site (Test/control) in the contralateral quadrants was performed 1 week after the first surgery. A higher reduction in probing depth and gain in CAL was observed in test site at 1, 3 and 6 months follow up amongst all the included participants. VAS score was lower at the test site as compared to the control sites. PSI scores were similar in both the sites. The adjunctive use of 445nm diode laser to surgical periodontal therapy contributed to improved short term clinical outcomes as assessed at the end of 6 months post- surgery. VAS score indicative of post -surgical discomfort were also lower for the laser treated sites. Hence adjunctive use of laser (445 nm wavelength) can be recommended for achieving more predictable clinical outcomes.

Comparative Assessment of the Effect of Three Various Local Drug Delivery Medicaments in the Management of Chronic Periodontitis.

AIM: The aim of this study was to evaluate the efficacy of three different local drug delivery medications in the treatment of chronic periodontitis. MATERIALS AND METHODS: Sixty participants, aged 30-55 years, were involved in the current research. Participants who fulfilled the inclusion criteria entered the study and were allocated at random to one of the three groups, each comprising 20 patients as: group A: Scaling and root planing (SRP) with local application of doxycycline gel, group B: SRP with local application of tetracycline fibers, and group C: SRP with local application of chlorhexidine gel. The plaque index (PI), the gingival index (GI), and periodontal pocket depth (PPD) were documented at baseline visit (prior to local drug delivery), and these indices were again documented 30 and 90 days post-local drug delivery. RESULTS: At baseline, GI score for doxycycline gel use decreased from 1.38 ± 0.05 to 0.94 ± 0.02, 1.36 ± 0.11 to 0.76 ± 0.19 for tetracycline fibers use, as well as from 1.38 ± 0.10 to 0.84 ± 0.21 for chlorhexidine gel use post 90 days. The PI value at baseline for doxycycline gel use lessened from 1.26 ± 0.01 to 1.02 ± 0.06, 1.30 ± 0.14 to 0.82 ± 0.16 for tetracycline fibers use, as well as 1.30 ± 0.22 to 0.98 ± 0.11 for chlorhexidine gel use post 90 days. At baseline, PPD values for doxycycline gel use decreased from 5.88 ± 0.24 to 3.72 ± 0.11, tetracycline fibers use lessened from 5.90 ± 0.09 to 3.02 ± 0.06, as well as for chlorhexidine gel group from 5.82 ± 0.18 to 3.44 ± 0.16 post 90 days. CONCLUSION: Within the limitations of the current research, it may be inferred that tetracycline fibers exhibited somewhat superior enhancement to chlorhexidine as well as doxycycline gel. CLINICAL SIGNIFICANCE: Local administration of antibacterial agents in continued or regulated delivery arrangement is employed to augment the actions of nonsurgical periodontal management, and it may be likely to attain gingival well-being by eliminating the requirement for invasive methods with the aid of local drug delivery arrangements. Chosen elimination or prohibition of microbial pathogens with locally administered antibacterial agents coupled with SRP is an efficient move toward treatment of chronic periodontitis.

ASSESSMENT OF LASER AND ANTIOXIDANT THERAPY EFFICACY IN TREATMENT OF CHRONIC GENERALIZED PERIODONTITIS.

Chronic generalized parodontitis is one of the most prevalent disorders among diseases of oral cavity, making the search for optimal treatment modalities of this disorder one of the mostressing matters to this day.  The purpose of this study was to assess outcomes of conventional therapy and secondary prevention of chronic generalized parodontitis with in combination with use of laser therapy and antioxidant drug treatment.   The study is presented as a joint multi-site investigation conducted by the group of authors from St. Petersburg and Saransk medical teaching and clinical institutions. The aim of the study was to improve the treatment and secondary prevention of chronic generalized parodontitis based on a pathogenetically substantiated scheme of laser and antioxidant therapy.   The total of 98 patients (31 male and 67 female) aged 30-50 years) with the 3 to 10 year history of moderate chronic generalized parodontitis were selected for the prospective study.  All patients were approximately equally divided into three groups according to the received treatment regimens: conventional treatment, laser therapy, and laser therapy with antioxidant medication. Several clinical indices were utilized for parodontal tissue assessment (PMA, SBI, AP), resistance of gingival capillary bed, osteal resorption. The lipid peroxide oxidation was determined by MDA, Fe2+ MDA  and phospholipase A2.   Additional implementation of laser and metabolic therapies sufficiently increases efficacy of conventional therapy and improves secondary prevention of chronic parodontitis. A marked decrease in structural-functional deviations and apparent recovery of microcirculatory vascular bed of parodontal tissue has been achieved. .

Evaluation of antioxidant capacity and clinical assessment of patients with chronic periodontitis treated with non-surgical periodontal therapy and adjunctive systemic antibiotherapy.

This study aims to evaluate the oxidative stress changes in patients with chronic periodontitis (CP) undergoing non-surgical periodontal therapy alone, compared with non-surgical periodontal therapy with adjunctive systemic antibiotic therapy. Sixteen patients with CP, randomly assigned into two equal groups, were treated either with scaling and root planing (SRP) + Amoxicillin + Metronidazole, each 500 mg, three times daily, for seven days (test group), or with SRP + placebo for seven days (control group). Venous blood and unstimulated saliva samples were collected. Non-surgical periodontal therapy was performed simultaneously with antibiotics administration. Oxidative stress balance was evaluated by measuring derivatives of reactive oxygen metabolites (d-ROMs) and the biological antioxidant potential (BAP) in plasma. After the microscopic evaluation of the pathological aspect of the epithelial cells (ECs), their number, viability and the presence of C-reactive protein (CRP) were reevaluated from saliva at seven days, while reduced glutathione (GSH) level, d-ROMs and BAP at three months. Wilcoxon and Kruskal-Wallis rank-tests were used for statistics. At three months, statistical significant reductions of mean periodontal pocket depth (PPD) and clinical attachment level (CAL) gains (both p=0.01) were found in test group. Full-mouth plaque score (FMPS) decreased statistically significant in control group (p=0.02), d-ROMs decreased statistically significant in test group (mean difference 116.24±107.6 U CARR, p=0.01). Mean GSH, BAP level, number of ECs, their viability and CRP were statistically non-significant. In test group patients, oxidative stress status changed from a very high level to a medium one, suggesting that adjunctive use of antibiotics could have contributed to the reduction of reactive oxygen metabolites, along with significant clinical improvements.

Relationship Between Periodontal Screening and Recording Index Scores and Need for Periodontal Access Surgery.

BACKGROUND: The validity of using pretreatment Periodontal Screening and Recording (PSR) index sextant scores to estimate periodontal access surgery needs is evaluated in patients with chronic periodontitis before and after completion of non-surgical periodontal therapy. METHODS: In 110 adults, pretreatment probing data identified 486 sextants with PSR scores of 4 and 125 sextants with PSR scores of 3. Periodontal access surgery needs for all sextants were determined prior to treatment and after completion of non-surgical periodontal therapy for 213 sextants in 38 patients by two experienced periodontist examiners. RESULTS: PSR scores of 4 identified untreated sextants with periodontal access surgery needs significantly better than PSR scores of 3 (odds ratio = 27.8; P <0.001) in multilevel, mixed-effects, logistic regression modeling analysis. However, only 37.6% of sextants with both pretreatment PSR scores of 4 and a pretreatment periodontal access surgery need continued to have surgical access needs after completion of non-surgical periodontal therapy. A higher percentage of sextants with PSR scores of 4 or 3 revealed periodontal access surgical needs when Class II or III furcation involvements and/or Grade II or III tooth mobility were also detected in the sextant than when these parameters were not detected. CONCLUSIONS: Pretreatment PSR index scores of 4 were a strong indicator of periodontal access surgery needs in untreated dentition sextants but markedly overestimated surgical access needs remaining after completion of non-surgical periodontal therapy. These findings raise questions about the usefulness of pretreatment PSR evaluations for estimating potential periodontal access surgery needs in patients to be initially treated with non-surgical periodontal therapy.

Assessment of interleukin-6 receptor inhibition therapy on periodontal condition in patients with rheumatoid arthritis and chronic periodontitis.

BACKGROUND: Overproduction of interleukin (IL)-6 may play a pathologic role in rheumatoid arthritis (RA) and chronic periodontitis (CP). The present study assesses IL-6 receptor (IL-6R) inhibition therapy on the periodontal condition of patients with RA and CP. METHODS: The study participants were 28 patients with RA and CP during treatment with IL-6R inhibitor, and 27 patients with RA and CP during treatment without IL-6R inhibitor. Periodontal and rheumatologic parameters and serum levels of cytokine and inflammatory markers and immunoglobulin G against periodontopathic bacteria were examined after medication with IL-6R inhibitor for 20.3 months on average (T1) and again 8 weeks later (T2). RESULTS: No differences were observed between the groups in any parameter values at T1, except for serum IL-6 levels. The anti-IL-6R group showed a significantly greater decrease in gingival index, bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and serum levels of IL-6 and matrix metalloproteinase (MMP)-3 from T1 to T2 than the control group (P <0.05). A significant correlation was found between changes in serum anticyclic citrullinated peptide levels and those in PD and CAL in the anti-IL-6R group (P <0.05), whereas both groups exhibited a significant association between changes in serum MMP-3 levels and those in BOP (P <0.05). CONCLUSION: Changes in periodontal and serum parameter values were different between the patients with RA and CP during treatment with and without IL-6R inhibitor.

[Efficient, minimally invasive periodontal therapy. An evidence based treatment concept]. / Effiziente, minimal-invasive Parodontitistherapie. Ein evidenzbasiertes Behandlungskonzept.

A large number of reports indicate beneficial effects of systemic antibiotics for patients with periodontal diseases. Although these advantages are clear in general, the specific relationship of benefit and risk in various clinical situations remains a subject of debate. Uncertainties persist regarding the individual prescription and combination with other procedures. Since the early 1990s it has been pointed out that systemic antibiotics given in the context of non-surgical subgingival debridement may reduce the need for periodontal surgery. Recent studies confirm these findings especially with regard to the combination of amoxicillin and metronidazole. However, these antibiotics should not be viewed as a substitute for thorough debridement, or as a means to compensate for improper oral hygiene. In addition, current evidence does not provide evidence for the indiscriminate use of just any antibiotic in any periodontal patient. A treatment protocol implementing the recent evidence is shown. It is noteworthy to realize that chronic and aggressive periodontitis today can be treated successfully with simple and cost-effective means in most instances.

Assessment of the effects of dentifrice on periodontal disease biomarkers in gingival crevicular fluid.

BACKGROUND: Periodontal disease has been studied primarily from clinical outcomes in lengthy human studies. Comprehensive biochemical profiling (metabolomics) has become a powerful tool for disease characterization and biomarker discovery. In a previous study, we performed a metabolomic analysis of gingival crevicular fluid collected from healthy, gingivitis, and periodontitis sites. Many metabolites associated with inflammation, oxidative stress, tissue degradation, and bacterial metabolism were found to be significantly induced by the diseases. METHODS: A panel of 10 markers was selected from the previous metabolomic study based on their statistical significance. Thirty-nine chronic periodontitis subjects were randomly assigned to a toothpaste regimen: control dentifrice (n = 21) or triclosan-containing dentifrice ([CT] n = 18). Subjects were instructed to use their assigned dentifrice twice daily for 6 weeks. Gingival crevicular fluid samples from six healthy, six gingivitis, and three periodontitis sites were collected from each subject at baseline, 1 week, and 6 weeks. The relative levels of the markers in the samples were determined by mass spectrometry. One-sided matched-paired t tests were performed to compare data from healthy, gingivitis, and periodontitis sites. RESULTS: Statistical analysis indicates that CT significantly decreased the levels of inosine, lysine, putrescine, and xanthine at the gingivitis sites as early as week 1. In contrast, control dentifrice had little effect. CONCLUSIONS: This result provides biochemical confirmation for the therapeutic effects of CT on gingivitis. Biomarkers were significantly altered by CT before clinical changes were observed, suggesting that the markers have predicative value for disease state assessment.

Prospective assessment of the use of enamel matrix derivative with minimally invasive surgery: 6-year results.

BACKGROUND: Minimally invasive surgery (MIS) is a surgical technique using very small incisions indicated for performing regenerative therapy in periodontal defects. The 11-month results from a prospective study of MIS were previously published. This article presents the 6-year results of that prospective study. METHODS: Patients from two private periodontal practices with advanced periodontitis who, after non-surgical therapy, had one or more sites with probing depths >or=6 mm were included in the study. An MIS surgical approach was used for all sites >or=6 mm. After surgical debridement, enamel matrix derivative (EMD) was placed into the bony defect. The surgical sites were reevaluated after >or=6 years. RESULTS: Six-year data were available on 142 sites in 13 patients. No significant differences were noted in the results between the two offices, and the data were combined. Probing depths (mean: 3.18 mm; SD: 0.59 mm) and attachment levels (mean: 3.93 mm; SD: 0.19) at 6 years were unchanged from the 11-month measurements. No recession from preoperative levels was noted. All sites continued to be considered clinically successful. CONCLUSIONS: The combination of MIS and EMD yielded significant reductions in probing depths and improvements in attachment levels while producing no detectable recession. The 11-month results remained stable at 6 years.

Assessment of aprotinin influence on periodontal clinical status and matrix metalloproteinases 1, 2 and their tissue inhibitors saliva concentrations in patients with chronic periodontitis.

PURPOSE: Assessment of the effect of treatment with aprotinin-containing drug on the clinical status of the periodontal tissue and on the concentrations of metalloproteinases released in the course of periodontitis (MMP-1, MMP-2) as well as their tissue inhibitors (TIMP-1 and TIMP-2) in the saliva of patients with chronic periodontitis (CP). MATERIAL/METHODS: The study involved 25 subjects with CP (39-68 years), including 16 women and 9 men. The patients were prescribed aprotinin preparation to be taken for 2 weeks. The control group (C) involved 14 healthy subjects (41-65 years), including 10 women and 4 men. Two periodontal indices were assessed: the approximal plaque index (API) and bleeding on probing index (BOP). Periodontal pocket depth and clinical attachment level were also evaluated. The concentrations of MMP-1 and MMP-2 as well as TIMP-1 and TIMP-2 were determined by the ELISA method. RESULTS: The mean salivary MMP-1 concentration in patients with CP was significantly higher before and after treatment, as compared to healthy subjects. The mean salivary MMP-2 concentration in CP patients at baseline was also higher as compared to the C group and increased after treatment. The mean salivary TIMP-1 and TIMP-2 concentration in CP patients was higher as compared to C group and increased after treatment. CONCLUSIONS: Since the mean MMPs levels were found to be growing it can be assumed that aprotinin has no significant effect on the regulation of MMPs in the saliva of CP patients. It thus seems that aprotinin application after scaling has no additional therapeutic effect.
