RESUMEN
INTRODUCTION: To systematically review existing scientific literature to determine, compare, and evaluate whether concentrated growth factors (CGF) or connective tissue grafts (CTG) is a better treatment alternative for patients with marginal tissue recession (MTR). METHODS: Electronic databases like PubMed, Embase, Scopus, and Google Scholar were screened from the last 20 years reporting treatment of MTR using CGF or CTG and other techniques. Periodontal parameters like probing depth, clinical attachment level, recession depth, recession width, keratinized tissue width, root coverage, increase in gingival thickness and plaque index, and gingival index were compared. Standardized mean difference was used as a summary statistic measure with a random effect model and P value <0.05 as statistically significant. RESULTS: Six studies fulfilled eligibility criteria and were included in qualitative synthesis, of which only 4 studies were suitable for meta-analysis. The pooled estimate through standardized mean difference signifies that CGF was superior to CTG in the reduction of probing depth, gingival index, and plaque index and gain in clinical attachment level while CTG was superior in reducing the recession depth and recession width. Both the procedures had an overall equal effect on keratinized tissue width and root coverage, but these differences were statistically insignificant (P>0.05). Publication bias through the funnel plot showed symmetric distribution without systematic heterogeneity. CONCLUSION: The present study suggests that treatment of MTR with CTG or CGF resulted in clinically favorable outcomes, but no statistically significant differences was observed between these 2 procedures regarding the outcome.
RESUMEN
INTRODUCTION: The aim of this article is to summarize, compare, and assess possible association in individuals with or without rheumatoid arthritis (RA) for periodontitis. EVIDENCE ACQUISITION: Three study repositories were searched for quantitative studies examining the relationship between periodontal disease and rheumatoid arthritis between 2000 and December 2022. Quality was evaluated using the Newcastle Ottawa Scale (NOS). The standardized mean difference (SMD), with a random effect model and a P value of 0.05 as the significance level, was utilized as a summary statistic measure. EVIDENCE SYNTHESIS: Fourteen papers were included in the descriptive synthesis. Thirteen were qualified for meta-analysis. Our findings suggest a link between the two conditions in terms of clinical attachment levels (CAL), tooth loss, Plaque Index, and probing depth. The estimated SMD for CAL was found to be 0.68 (95% CI: 0.15-1.21) (P<0.01). For tooth loss, the forest plot analysis revealed an SMD of 1.62 (95% CI: 0.48-2.76) (P=0.005). Similarly, for pocket depth, the SMD was 0.53; CI: 0.07-0.99 (P>0.05). The pooled estimates for plaque index were 0.29; CI: 0.03-0.61 (P>0.05). The funnel plot showed a symmetric distribution with the absence of systematic heterogeneity. CONCLUSIONS: Although our data suggest a link between periodontal disease and rheumatoid arthritis, larger population-based investigations are needed to validate this connection. Case-control studies must pave the way to more rigorous investigations with well-defined populations and clinical outcomes as primary outcome measures.

INTRODUCTION: Parkinson's disease (PKD) is neurodegenerative disorder marked by tremors, bradykinesia, muscle rigidity and reduction in precise hand movements which could lead to improper oral hygiene and Periodontal disease. Current systematic review aims to review existing literature and provide assessment of periodontal health in PKD patients through a meta-analysis METHODS: Review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and registered in PROSPERO-CRD42023451700. Databases were searched for studies having sufficient data on periodontal health in patients with PKD compared to healthy controls and reporting outcomes in terms of various periodontal parameters of probing depth (PD), plaque index (PI), clinical attachment level (CAL), presence of bleeding on probing and gingivitis. Quality assessment of included was evaluated using Newcastle Ottawa Scale (NOS). RESULTS: Eleven studies fulfilled the eligibility criteria, of which ten studies were suitable for meta-analysis. Pooled estimate through the SMD showed that all periodontal parameters were altered and significantly deteriorated in PKD compared to controls but this group differences were statistically insignificant (p > 0.05). Publication bias through the funnel plot showed symmetric distribution with absence of systematic heterogeneity. CONCLUSION: Parkinson's disease could be a possible factor in deterioration of periodontal health.
RESUMEN
A meta-analysis of scientific literature was conducted to ascertain the superiority between allografts and other regenerative grafts for maxillary sinus floor augmentation (MSFA). Review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and registered in PROSPERO-CRD42023392766. Electronic databases like PubMed, Google scholar and Ebsco Host were searched from 2000 to December 2022 for studies reporting MSFA using allografts or other regenerative grafts. Quality assessment of included studies was evaluated using the Cochrane risk of bias (ROB)-2 tool for randomized controlled trials through its domains. Risk of bias summary graph and ROB summary applicability concern were plotted using RevMan software version 5.3. The standardized mean difference was used as a summary statistic measure with random effect model and P value <0.05 as statistically significant. Four studies fulfilled the eligibility criteria and were included in qualitative synthesis, of which all 4 studies were suitable for meta-analysis. Pooled estimate through standardized mean difference signifies that new bone formation was more or less similar for both graft materials, whereas regenerative grafts showed more residual bone grafts (P>0.05). Publication bias through funnel plot showed symmetric distribution with the absence of systematic heterogeneity. Both allografts and other regenerative grafts are equally effective in the MSFA in terms of new bone formation, whereras regenerative grafts showed more residual bone grafts. Furthermore, randomized controlled trials are required to establish evidence in outcomes involving sinus floor augmentation and different graft materials.
RESUMEN
BACKGROUND: Interleukin 22(IL-22), a recently identified, Th-22 associated cytokine has a key role in the production of human ß defensin-2(hBD-2) and hence an indirect role in innate, nonspecific immunity. Hence this study was conducted as preliminary research to quantify and correlate the levels of IL-22 and hBD-2 in periodontal disease. MATERIALS AND METHODS: Gingival crevicular fluid from subjects with chronic periodontitis (n = 27), gingivitis (n = 25) and healthy controls (n = 27) were obtained for the study. The periodontal status of each subject was assessed by criteria based on plaque index, gingival index, bleeding on probing, probing depth and clinical attachment loss. The levels of IL-22 and hBD-2 were measured in GCF samples with an enzyme-linked immunosorbent assay. RESULT: Periodontal parameters were described and reported as mean values. The distribution and comparison of clinical parameters and gingival crevicular fluid IL-22, hBD-2 levels in healthy controls, gingivitis and chronic periodontitis groups were assessed using one way ANOVA test. Post Hoc Bonferroni test was used for intergroup comparisons. Association among the IL-22 , hBD-2 and clinical parameters in all three groups were examined using Pearson's correlation test.The IL-22 level was significantly greater in chronic periodontitis group than healthy controls (P < 0.001) and gingivitis group (P < 0.001). The hBD-2 level was significantly higher in the chronic periodontitis group compared to gingivitis (P = 0.003) and healthy controls (P < 0.001). The results also showed a statistically significant correlation (P = 0.002) between IL-22 and hBD-2 concentration in chronic periodontitis group. CONCLUSION: These results indicate the role of IL- 22 and hBD-2 in the innate immune response during periodontitis.
RESUMEN
BACKGROUND: Currently, the leading theme in mucogingival surgery is the correction of gingival recession defects. Free gingival graft (FGG) has been successfully in use in this category of reconstructive therapeutic modality. OBJECTIVES: The aim of this systematic review was to evaluate the literature with respect to efficacy of FGG in the management of Miller Class I and II localized gingival recessions. DATA SOURCES: Search strategies were performed via electronic database which included Pubmed-Medline, Google scholar and manual search using University library resources. Two reviewers assessed the eligibility of the studies. STUDY ELIGIBILITY CRITERIA: Controlled clinical trials, randomized clinical trials and longitudinal studies evaluating recession areas treated by FGG with minimum of 6 months follow up were included. In-vitro and animal studies, studies mainly done on Miller Class III and IV gingival recession defect, studies on multiple gingival recessions and case series and case reports were excluded from the search. RESULTS: The electronic and manual search identified a total of 557 articles. A final screen consisted of 39 articles out of which 17 articles were selected for full-text assessment. Finally, 7 articles were selected for detailed evaluation for this systematic review. FGG has shown significant results in all the studies except for one study. CONCLUSION: FGG produces substantial results, however, highly depends on the case selection and operator's skill and experience. FGG gives an impression of being the best alternative option in zones where gingival recession presents with inadequate width of attached gingiva and depth of vestibular fornix.
RESUMEN
The aim of the present systematic review was to analyze the factors that affect the outcome of subepithelial connective tissue graft (SCTG) for managing Miller's class I and class II isolated gingival recession defect. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for systematic reviews were used. Quality assessments of selected articles were performed. Data on root surface condition, recession type defect, flap thickness, different flap designs, different harvesting techniques, presence/absence of the epithelial collar, graft thickness, flap tension, suturing techniques, and smoking-related outcomes on root coverage were assessed. The SCTG procedure provides the best root coverage outcomes for Miller's class I and class II recession. The critical threshold of flap thickness was found to be 1 mm. Maximum root coverage was achieved by envelope and modified tunnel technique. SCTG with the epithelial collar does not provide additional gains than SCTG without the epithelial collar. The thickness of SCTG for root coverage was found to be 1.5-2 mm. Greater flap tension and smoking adversely affect root coverage outcomes. Analysis of the factors discussed would be of key importance for technique selection, and a combined approach involving factors favoring outcomes of SCTG could be of clinical relevance in recession coverage.

BACKGROUND: The need-of-the-hour is a material that can support coronally advanced flap (CAF) procedures in treatment of gingival recession. Recent literature shows that various bone substitutes are being used for this procedure. This study clinically evaluates the outcomes of CAF with and without bioactive glass putty (NovaBone®) in terms of root coverage, gains in keratinized tissue height, and root coverage esthetic score in multiple gingival recession defects. METHODS: Ten healthy patients (age range 18-45 years) with multiple bilateral (n = 40 test 20; control 20) and comparable Miller's Class I or Class II gingival recession defects were selected. The defects were randomly assigned by a computer-generated list to either test (CAF + bioactive glass putty) or control (CAF alone) groups. Clinical parameters included gingival recession (GR), probing pocket depth (PPD), clinical attachment level (CAL), keratinized tissue height (KTH), root coverage esthetic score (RES) evaluated at baseline and at 6 months post-surgery CAF with or without bioactive glass putty. RESULTS: Six months post-surgery all clinical parameters showed significant reductions. Gingival recession showed significant reduction both in test and control groups (2.0 ± 0.47 mm and 2.3 ± 0.48 mm, respectively; p < 0.05) with no intergroup difference. The exposed root was covered by 72% (test) and 79% (control). CAL gain was also significant in both groups (test: 2.7 ± 0.67 mm; control: 2.8 ± 0.78 mm; p < 0.05) with no intergroup difference. Keratinized tissue height gain was significant in both the groups (test group: 1.2 ± 0.42 mm; control group: 0.9 ± 0.57 mm) with no intergroup difference. Also, the RES was significant for both the test and control groups (7.2 ± 2.78 and 7.7 ± 1.41 respectively) with no intergroup differences. CONCLUSIONS: In isolated Class I/II GR defects, CAF associated with bioactive glass putty provided no significant difference in root coverage, CAL, KTH or RES compared to CAF alone. However, statistically significant gains were seen in all the parameters in both groups as compared to baseline. We refute the claims of the recent studies using a bone substitute for root coverage. Further long-term clinical trials are warranted to substantiate our results.

BACKGROUND: Platelet-rich concentrates are the most widely used regenerative biomaterials. Stimulation and acceleration of soft and hard tissue healing are due to local and continuous delivery of growth factors and proteins, mimicking the needs of the physiological wound healing and reparative tissue processes. This article aims to evaluate the clinical efficacy of open flap debridement (OFD) with or without platelet-rich fibrin (PRF) in the treatment of intrabony defects. MATERIALS AND METHODS: Twenty subjects with forty intrabony defects were treated with either autologous PRF with open-flap debridement (test, n = 20) or open-flap debridement alone (control, n = 20). Soft tissue parameters included: Plaque index, sulcus bleeding index, probing depth, relative attachment level and gingival marginal level (GML). The hard tissue parameters included-distances from: Cement enamel junction to the base of the defect (CEJ-BOD): Alveolar crest to the base of the defect (AC-BOD): And CEJ to AC. The parameters were recorded at baseline and at 9 months postoperatively calculated using standardized radiographs by image-analysis software. RESULTS: Statistically significant (0.005*) intragroup improvements were seen with all the hard and soft parameters in both test and control groups, except for GML. Statistically significant improvements were seen with the mean defect fill (CEJ-BOD and AC-BOD) (P = 0.003*) when intergroup comparisons were made. CONCLUSIONS: Adjunctive use of PRF with OFD significantly improves defect fill when compared to OFD alone. PRF has consistently been showing regenerative potential; it is simple, easy and inexpensive biomaterial compared with bone grafts.
RESUMEN
Oral telangiectatic granuloma is a benign hyperplastic lesion occurring in response to trauma or chronic irritation in the oral cavity. The characteristic histological appearance comprises of typical granulation tissue with a proliferation of small thin-walled blood vessels in the loose connective tissue. We describe a case of a 36-year-old female who had a swelling in the left maxillary region which was associated with the intrabony defect. An internal bevel gingivectomy was performed, and the histopathological report was suggestive of telangiectatic granuloma. The intrabony defect was managed with the placement of platelet rich fibrin plug in the defect. A follow-up at 6 months showed no recurrence and no loss in the width of keratinized tissue. The aim of this case is to highlight the rare association of intrabony defect with telangiectatic granuloma and the need for histopathological diagnosis in such lesions.
RESUMEN
BACKGROUND: Gingival recession is both unpleasant and unesthetic. Meeting the esthetic and functional demands of patients with multiple gingival recessions remains a major therapeutic challenge. We compared the clinical effectiveness of Zucchelli's technique and tunnel technique with subepithelial connective tissue graft (SECTG) for multiple gingival recessions. METHODS: Twenty systemically and periodontally healthy subjects having 75 recession defects (Miller's class I or II, 39 test and 36 control sites) were included. After initial nonsurgical therapy, test sites were treated with Zucchelli's technique and control sites with tunnel technique with SECTG. Plaque index, bleeding index, pocket depth, recession depth, clinical attachment level, and keratinized gingiva height were evaluated at baseline, 3 and 6 months post-surgery. RESULTS: The mean root coverage was 89.33% +/- 14.47% and 80.00% +/- 15.39% in the test and control groups respectively, with no significant difference between groups. Statistically significant root coverage was obtained for 82.50% +/- 23.72% and 71.40% +/- 20.93% of defects in the test and control groups, respectively. CONCLUSION: Zucchelli's technique is effective for the treatment of multiple adjacent recessions in terms of both root coverage and keratinized tissue gain, irrespective of the number of defects. Moreover, this technique does not require an additional surgical site as required in the gold standard SECTG.

Dentinal hypersensitivity is one of the oldest recorded complaints of discomfort to mankind and yet there appears to be no permanent treatment for this clinical condition. This study was designed to evaluate the clinical efficacy of potassium binoxalate gel and neodymium:yttrium-aluminum-garnet (Nd:YAG) laser on dentin hypersensitivity for a period of 9 months. Eighty teeth (20 subjects, 25-55 years old, M = F) were evaluated in a split-mouth design to receive potassium binoxalate (group A, 40 teeth) and Nd:YAG (group B, 40 teeth: 1 W, 10 Hz, and 60 s, irradiated twice). The diameter of output beam was about 300 µm with a distance of 2 mm between laser fiber or tip and tooth surface. The clinical efficacy was evaluated by air-blast test and cold-water test using visual analog scale. Electron microscopy photomicrographs were taken to confirm the results. Analysis was done at baseline; immediately post-treatment; and at 3, 6, 9 months post-treatment. Student's paired and unpaired T tests were used to evaluate the statistical analysis. Both treatment modalities were effective in reducing dentine hypersensitivity. However, Nd:YAG laser was better when intragroup comparison was made at 9 months post-treatment. Nd:YAG lasers is better in long-term treatment (up to 9 months) owing to the melting of dentinal tubules. However, due to depth of penetration of microcrystals, gel was better when ease of the procedure is considered. Nevertheless, both treatment modalities resulted in recurrence. Hence, further studies are needed to discover an agent, which can be considered as a "gold standard".

BACKGROUND: Superoxide dismutase (SOD), an antioxidant acting against superoxide (oxygen radical, O(2)(â-)), it is released in inflammatory pathways and causes connective tissue breakdown. Increased SOD activity in inflamed gingiva may indicate increased O(2)(â-) radical generation by neutrophils and other inflammatory cells at the diseased site. The aim of the study was to evaluate the effects of non-surgical periodontal therapy (NSPT) on SOD levels in gingival tissues of chronic periodontitis patients. METHODS: Forty subjects: 20 periodontally healthy (Control) and 20 chronic periodontitis (Test); age range 24-55 years were recruited. Gingival tissue samples were collected by excising the inner lining of the periodontal pocket at baseline (prior to non-surgical periodontal therapy) and 2 months post therapy. In controls, tissue samples were obtained immediately after tooth extraction scheduled for orthodontic reasons. Clinical parameters included probing depth, clinical attachment level, gingival index, bleeding index, plaque index. SOD activities were assessed spectrophotometrically at baseline and 2 months post NSPT, results were analysed statistically. RESULTS: At baseline, patients with chronic periodontitis had higher mean SOD activity (2.73 ± 1.36) than the control subjects (1.12 ± 1.13) with p=0.00003 (p< 0.05). At 2 months post NSPT median SOD level (1.00) had come close to median SOD value of control group (0.85); p=0.99 (p> 0.05). The resolution of inflammation with successful NSPT resulted in decreased SOD levels as in control group. Clinical parameters in patients with chronic periodontitis showed a significant improvement 2 months post NSPT (p< 0.05). CONCLUSION: Non-surgical periodontal therapy significantly improves the clinical parameters and restores previously increased SOD levels to normal in chronic periodontitis patients.
