RESUMO
Periodontal pockets are characteristic of periodontitis. Scaling and root planing is the gold standard for periodontitis treatment. Additional local antimicrobials are recommended in patients with a probing depth of ≥ 5 mm. This study aims to determine the effectiveness of chlorhexidine compared to other local antimicrobials in periodontitis. Searches were conducted using the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) guidelines. Meta-analysis was performed on studies that met inclusion criteria after risk of bias assessment. Meta-analysis between chlorhexidine chips and other antimicrobials showed a mean difference in probing depth after one month of 0.58 mm (p < 0.00001) whereas after three months the mean difference in probing depth was 0.50 mm (p = 0.001), index plaque 0.01 (p = 0.94) and gingival index - 0.11 mm (p = 0.02). Between chlorhexidine gel and other antimicrobials showed a mean difference in probing depth of 0.40 mm (p = 0.30), plaque index of 0.20 mm (p = 0.0008) and gingival index of -0.04 mm (p = 0.83) after one month. Chlorhexidine chips were more effective on the gingival index than other antimicrobials after three months. The other antimicrobials were more effective than chlorhexidine chips on probing depth after one and three months, and than chlorhexidine gels on plaque index after one month.

This study aims to evaluate the clinical, cognitive, and psychomotor changes that emerged among patients with gingivitis and patients with periodontitis via mobile application assistance. Forty subjects were randomly and evenly distributed into test and control groups and were administered a professional mechanical plaque removal (PMPR) procedure. The clinical parameters examined were bleeding on probing (BoP), probing pocket depth (PPD), and the oral hygiene index (OHI-S). The test group was administered a mobile application intervention, namely PerioUICare, which provided users with continuous education and motivation and served as a daily dental hygiene reminder. The comparative results of the mean values of all parameters between the groups (inter-group) and within the groups (intra-group) after one- and three-month evaluations were analyzed. A one-month inter-group evaluation uncovered significant differences in the BoP, PPD, cognitive, and psychomotor scores of subjects with gingivitis and the BoP, OHI-S, cognitive, and psychomotor scores of subjects with periodontitis. A three-month inter-group evaluation revealed significant differences across all parameters except for PPD in subjects with periodontitis. The results of the intra-group comparison demonstrated statistically significant differences in all parameters in the test group but no significant differences in the cognitive and psychomotor scores of the control group. This study revealed that mobile application-based support for periodontal treatment can be considered effective.
RESUMO
OBJECTIVE: This double-blind randomized clinical trial assessed the effectiveness of 0.2% hyaluronic acid (HA) gel as an adjunct to scaling and root planning (SRP) in patients with periodontitis and type 2 diabetes mellitus (DM), focusing on changes in clinical periodontal parameters, the expression of inflammatory mediators, and oral pathogens. MATERIALS AND METHODS: The randomized clinical trial involved 36 participants, 18 DM patients, and 18 healthy patients. The participants in each group were randomly assigned to receive placebo or HA gel after SRP. Gingival crevicular fluid and subgingival plaque samples were taken before treatment and at 4-week follow-up. Clinical parameters, interleukin-1ß (IL-1ß) and IL-10 levels, and proportions of Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn) were evaluated at baseline and follow-up. STATISTICAL ANALYSIS: Paired t-test (parametric data) or Wilcoxon signed-rank test (nonparametric data) was used for intragroup comparison between baseline and follow-up, and comparisons between groups one-way analysis of variance test (parametric data) or Kruskal-Wallis test (nonparametric data). RESULTS: At 4 weeks, most of the groups showed statistically significant decreases (p ≤ 0.05) in various clinical and biomolecular parameters. However, there were exceptions: the pocket probing depth (PPD) and clinical attachment loss (CAL) parameter did not significantly decrease for the placebo (p > 0.05) non-DM group, and the IL-10 parameter in the DM HA gel group (p = 0.108). Regarding bacterial proportions, the non-DM and DM placebo group exhibited significant test results for Pg after 4 weeks (p ≤ 0.05). In the case of Fn bacteria proportions, they decreased in all groups, but these results were not statistically significant (p ≥ 0.05). An intergroup analysis revealed no significant differences (p ≤ 0.05) for bleeding on probing (BOP), PPD, and both proinflammatory and anti-inflammatory cytokines. Only clinical attachment loss (CAL) exhibited a statistically significant intergroup difference 0.042. CONCLUSION: The use of 0.2% HA gel into periodontal pockets alongside SRP, for both diabetic and healthy individuals, showed no statistically significant variances in clinical, biomolecular, and microbiological measures.
RESUMO
Introduction: Periodontitis is an inflammation of the periodontal apparatus leads to destruction of connective tissue attachment and tooth loss. Red complex bacteria may contribute to disease initiation. Bacterial infection in periodontitis leads to a low-grade chronic infection and inflammation in distant organs. Notably, aging can affect the immune response. Objectives: The aim of this study was to analyze the effect of aging on oral hygiene and inflammation condition. Moreover, to evaluate the correlation between the oral hygiene condition and red complex bacterial load in subgingival plaque. Materials and methods: In this cross-sectional study, we examined 20 adult and 20 elderly subjects with periodontitis. Clinical parameters included Oral Hygiene Index Simplified (OHI-S) and Papillary Bleeding Index (PBI) were recorded. Subgingival plaque was collected from the tooth with a probing depth of 5-7 mm and analyzed with a reverse transcription polymerase chain reaction (RT-PCR) for red complex bacteria quantification. Statistical analysis was performed, respectively. Results: Both groups had poor oral hygiene conditions, reflected by high OHI-S and PBI. The quantity of red complex bacteria (P. gingivalis, T. denticola, T. forsythia) in the elderly group was significantly higher in comparison to the adult group. There was significant strong linear relationship between OHI-S and red complex bacteria (r < 1, p < 0.05). Only P. gingivalis bacteria with PBI values had a strong linear relationship and statistically significant. (r < 1, p < 0.05). P. gingivalis load was significantly higher than T. denticola and T. forsythia load, and it correlated with poor oral hygiene in the adult and elderly groups and with PBI in the elderly group. Conclusions: Aging affects to the red complex bacterial load and oral hygiene condition, but not the inflammation. These findings contribute to the development of novel treatment strategies focusing on bacterial aspect for periodontitis in the elderly.
RESUMO
Background: Periodontitis is an inflammatory disease caused by specific microorganisms that gradually damage the periodontal and tooth-supporting tissues, thereby reducing a person's quality of life. Periodontal disease is closely associated with high reactive oxygen species (ROS) levels, with a high receptor activator of nuclear factor kß ligand (RANKL)/osteoprotegerin (OPG) ratio. Konjac glucomannan (KGM) is produced from the porang root, which has several properties. For example, it can reduce oxidative stress. The current study analyzed the osteoclastogenesis inhibitory and antioxidant properties of KGM based on histomorphometric findings, RANKL/OPG ratio, and ROS levels in the Swiss Webster mouse periodontitis model. Methods: Eight-week-old male Swiss Webster mice were divided into the nonligation, nonligation + KGM, ligation + Porphyromonas gingivalis, and ligation + P. gingivalis + KGM groups. KGM suspension was administered for 14 days. Periodontitis induction was performed from 7th to 14th day. On the 14th day, maxillae, gingival, and gingival crevicular fluid samples were collected to assess the histomorphometry of bone damage, gene expression ratio of RANKL/OPG, and ROS protein levels. Results: The periodontitis group pretreated with KGM presented with significantly reduced alveolar bone damage, RANKL/OPG ratio, and ROS level than without KGM group. KGM treatment had no harmful/toxic effects in mice. Conclusion: Administration of KGM could act as an adjunctive in periodontal therapy by suppressing periodontal disease via osteoclastogenesis inhibitory and antioxidant properties.
RESUMO
Aging can change the ability to respond to various stimuli and physical conditions. A decreased immune response is a form of deterioration of function in older people, who then become more vulnerable when exposed to pathogens. Periodontitis is an inflammatory disease of the periodontal tissues that often occurs in older people. This study aimed to clinically analyze the periodontal status and cytokine levels of IL-1ß, TNF-α, and IL-10 in older people and adults with periodontitis. This clinical study examined 20 persons in a group of older people and 20 persons in a group of adults. The clinical measurements of periodontal status included the Simplified Oral Hygiene Index (OHI-S), Plaque Index (PlI), and Papilla Bleeding Index (PBI). The cytokine levels in gingival crevicular fluid (GCF) were quantified by using ELISA kits. The OHI-S, PlI, and PBI were found to be higher in the older group. The mean values of cytokines were higher in the older group than in adults, although no statistically significant differences were found. A strong correlation was found between the clinical measurements and the cytokine levels in the GCF. There was an increasing tendency of pro-inflammatory and anti-inflammatory cytokines in the older group compared to the adult group.
RESUMO
OBJECTIVES: Interferon-gamma (IFNg) is an immune-regulatory cytokine with a role in host responses to periodontitis. Genetic factors have been reported to modify the corresponding protein expression. The objective of this study was to evaluate the association and role of IFNg polymorphisms, such as IFNg +874 A/T, and the susceptibility to periodontitis. MATERIALS AND METHODS: A total of 100 unrelated subjects were included in the present study. Genomic deoxyribonucleic acid (DNA) was obtained from peripheral blood of 43 patients with mild periodontitis and 57 patients with severe periodontitis. The determined clinical parameters of periodontitis included probing depth, clinical attachment loss, and papilla bleeding index. The oral hygiene indicators were also assessed. The level of IFNg was determined from the gingival crevicular fluid by enzyme-linked immunosorbent assay technique. The IFNg +874 A/T polymorphisms were analyzed from peripheral blood by the method of restriction fragment length polymorphism-polymerase chain reaction. STATISTICAL ANALYSIS: Statistical analysis of the results was conducted using chi-squared testing for categorical data. Independent t-tests and Mann-Whitney U tests were used for numeric data. Kruskal-Wallis testing was used to compare genotypes concerning for IFNg +874 A/T polymorphism. A p-value < 0.05 was assumed for statistical significance. RESULTS: Analysis of the IFNg +874 A/T polymorphism showed no significant differences with the level of IFNg. No significant differences were observed either in IFNg +874 A/T polymorphism between the subjects with mild periodontitis and those with severe periodontitis (p > 0.05). The subjects with severe periodontitis showed marginally but not significantly higher levels of IFNg compared with subjects with mild periodontitis (p > 0.05). CONCLUSION: The polymorphism of IFNg +874 A/T was not associated with the level of IFNg nor with the risk of periodontitis in this study.
RESUMO
Increasing evidence has shown an association between periodontitis and cognitive impairment. Subgingival microbiota play a great role in periodontitis pathogenesis. However, the correlation between the subgingival microbiome and cognitive impairment remains unclear. This study aimed to evaluate the red and orange complex subgingival microbiome of cognitively impaired and cognitively normal elderly Indonesian subjects with periodontitis. Twenty-eight elderly subjects diagnosed with periodontitis underwent two cognitive examinations using the Hopkins Verbal Learning Test and the Mini-Mental State Examination. Gingival crevicular fluid taken from the periodontal pocket, at a depth between 5 and 7 mm, using a paper point was used as the subgingival samples. The subgingival microbiome in the cognitive impairment group (n = 14) and cognitively normal group (n = 14) was compared using the 16S rRNA Metagenomic iSeq™ 100 Sequencing System. There was ß-diversity in the subgingival microbiota between the cognitively impaired and cognitively normal subjects. The metagenomic analysis showed a higher abundance of Porphyromonas and Treponema bacteria in the cognitive impairment group than in the normal cognitive group (p < 0.05). The abundance of Porphyromonas gingivalis and Treponema denticola was higher in the cognitively impaired elderly subjects. The role of P. gingivalis and T. denticola in the pathogenesis of cognitive impairment needs further investigation.
RESUMO
BACKGROUND: The relevance of root's convergence with trauma from occlusion has not been widely studied. Anatomically, alveolar bone support can be divided into several levels. The root which is convergent gives a critical mass of alveolar bone support to the teeth so that it is inadequate to stabilize the tooth. AIMS: The purpose of the study is to observe the relevance of root's convergence with traumatic from occlusion. SETTINGS AND DESIGN: This was an observational retrospective design. SUBJECTS AND METHODS: Samples in this study consist of periapical radiograph of the maxillary and mandibular first molar teeth from the patients with periodontitis, which are aggravated with trauma from occlusion. For the root's convergence measurement, we use a line on the outer edge of the mesial, distal, occlusal, and apical planes of the tooth. To get the cutoff point of the root convergence value, receiver operating characteristic-curve test is performed. STATISTICAL ANALYSIS USED: Spearman test results, based on the analysis of gingival recession and loss of attachment, indicating that each increase of root convergence value will be followed by a decrease of attachment. CONCLUSIONS: Tooth which has a convergent/very convergent root contour can contribute to trauma from occlusion.
RESUMO
Abstract Objective: To measure the level of immunoglobulin G (IgG) in the gingival crevicular fluid (GCF). Material and Methods: A total of 158 patients aged >45 years were examined for periodontitis and interviewed regarding their menopausal status. The non-menopause group entailed female patients with periodontitis without menopause (n=23). The menopause group included females who stopped menstruating since >1 year, had a pocket depth of 4-5 mm, and did not have other systemic conditions (n=40). Samples were selected based on periodontal and menopausal status. In total, 63 samples of GCF were collected from the participants and tested using an enzyme-linked immunosorbent assay kit for IgG. Results: The median level of IgG in the menopause group was 39.50 (g/mL, whereas that of the non-menopause group was 41.08 (g/mL. There was a positive correlation between the plaque index and IgG level in both groups. In contrast, there was a negative correlation between age and IgG level. However, there was no correlation between plaque index and age regarding the IgG level in both groups (p>0.05). Conclusion: The IgG levels in the menopause group were lower than those in the non-menopause group. As such, menopausal females should take great care of their overall health, including the periodontium.

Objective: To analyze the relationship between age, body mass index (BMI), bone mineral density (BMD), and alveolar bone resorption with menopause duration in postmenopausal women. Material and Methods: A cross-sectional study was developed involving 59 subjects, aged 45 to 80 years and categorized the duration of menopause as ≤5 years and >5 years. Body mass index measurement and menopause duration were collected. Bone loss seen on radiography was measured by drawing a vertical line from the cementoenamel in the distal part of the 36 teeth and the mesial portion of 46 teeth to the base of the bone marked by the lamina dura intact. Categorical determinations of age, BMI, BMD, and alveolar bone resorption were based on receiver operating characteristic (ROC) curves. Were used Pearson correlation and Spearman correlation tests with the significance level set at 5%. Results: The majority of subjects (54.2%) with menopause duration >5 years were aged >54.5 years, most had BMI >24.2 kg/m2 (39%), had bone resorption >2.95 mm (52.5%), and had bone density ≤73.89 (49.2%). Pearson and Spearman correlation tests showed no significant correlation between age, BMI, bone density, and alveolar bone resorption (p>0.05). Conclusion: The longer the duration of menopause showed a tendency for lower bone density and higher age, BMI, and bone resorption.
