Aim To evaluate the effectiveness of mobile applications and text messages, compared with conventional oral hygiene instructions, for improving oral health knowledge and/or reducing gingival inflammation, when delivered to adolescents, adults and mothers of young children. Methods Randomized clinical trials evaluating the use of mobile applications or text messages related to oral hygiene and/or oral health education were screened. A search was performed in the Medline‐PubMed, Scopus and Embase databases and the grey literature. The eligible studies comprised those related to plaque, gingival bleeding and/or oral health knowledge as outcomes. The risk of bias was assessed with the Cochrane tool and the GRADE system. Two meta‐analyses were carried out. Results Among the fifteen studies selected, twelve (80%) used text messages and thirteen (87%) showed better results when mobile technology was used. The pooled SMD for the dental plaque index (n = 10 studies) was −9.43 (95% CI −14.36 to −4.495; I2 = 99%, p < 0.001), and that of gingival bleeding (n = 7 studies) was −8.54 (95% CI −13.16 to −3.91; I2 = 99%, p < 0.001), indicating significant improvement in dental plaque control and gingival bleeding for groups that received the mobile health (mHealth) strategy. Conclusion mHealth can be used as an adjunct component in managing gingivitis, acquiring oral health knowledge and improving oral hygiene.
Current evidence suggests that periodontal disease may be associated with systemic diseases. This paper reviewed the published data about the relationship between periodontal disease and cardiovascular diseases, adverse pregnancy outcomes, diabetes and respiratory diseases, focusing on studies conducted in the Brazilian population. Only a few studies were found in the literature focusing on Brazilians (3 concerning cardiovascular disease, 7 about pregnancy outcomes, 9 about diabetes and one regarding pneumonia). Although the majority of them observed an association between periodontitis and systemic conditions, a causal relationship still needs to be demonstrated. Further studies, particularly interventional well-designed investigations, with larger sample sizes, need to be conducted in Brazilian populations.
Periodontal diseases comprise a number of infectious and inflammatory conditions brought about by the interaction between supragingival and subgingival biofilms and the host inflammatory response. Periodontal diseases should be considered systemic conditions. This means that they are both modulated by the body's systems and play a role as a risk factor for systemic derangements. The current evidence supports some of these interactions, such as smoking as a risk factor for periodontal disease and diabetes mellitus, as both influenced by and influencing inflammatory changes in the periodontal tissue. Other potential associations are still being researched, such as obesity, hormonal changes, cardiovascular disease, and adverse outcomes in pregnancy. These, and others, still require further investigation before the repercussions of periodontal disease can be fully elucidated. Nevertheless, at the present time, the treatment of periodontal diseases-and, most importantly, their prevention-enables adequate intervention as a means of ensuring periodontal health.
The aim of the present study was to evaluate the association between metabolic syndrome (MS) and periodontitis (PD), through a systematic review and meta-analysis. Original observational studies assessing the association between MS and PD in adults, published before May 11th (2017), were identified through electronic searches of MEDLINE, EMBASE and Cochrane Library databases. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline was used. For studies to be included, they had to mention the criteria used to diagnose MS and to have used at least one clinical measure to diagnose PD. There was no language restriction. Three reviewers independently identified eligible studies for possible inclusion in the systematic review and meta-analysis. The quality of the studies was evaluated by the Newcastle-Ottawa scale for observational studies. A random model meta-analysis was conducted. The strategies used to investigate heterogeneity were sequential analysis, subgroup analysis, univariate meta-regression and sensitivity analysis. Thirty-three studies met the inclusion criteria for the systematic review, and 26 had enough information to be included in the meta-analysis, totaling 52,504 patients. MS and PD were associated with an odds ratio of 1.38 (95%CI 1.26-1.51; I2 = 92.7%; p < 0.001). Subgroup analysis showed that complete periodontal examination (I2 = 70.6%; p < 0.001) partially explained the variability between studies. The present findings suggest an association between MS and PD. Individuals with MS are 38% more likely to present PD than individuals without this condition. Prospective studies should be conducted to establish cause and effect relations between MS and PD.
Comprehensive periodontal treatment and strict plaque control significantly improved periodontal health; however, no reduction of PTLBW rates was observed. Thus, remaining periodontal inflammation posttreatment cannot explain the lack of effect of periodontal treatment on PTLBW. Clinical relevance This study demonstrated that periodontal diseases may be successfully treated during pregnancy. Our results do not support a potential beneficial effect of periodontal treatment on PTLBW.
Aim: Evaluate factors associated with pain and analgesic consumption following nonsurgical periodontal therapy. Materials and methods:The sample consisted of 218 patients with chronic periodontitis, submitted to non-surgical scaling and root planing under local anaesthesia at a public dental service in southern Brazil. The data collection instruments included a demographic questionnaire, as well as State-Trait Anxiety Inventory, Corahʼs Dental Anxiety Scale, Visual Analogue Scale, Numerical Rating Scale and Verbal Rating Scale.The presence and intensity of pain were evaluated at 2, 6, 12, 24 and 48 hr after scaling and root planing.Results: A total of 52.3% of the patients reported mild intensity pain at some point during the 48 hr after scaling and root planing with local anaesthesia. Smoking (PR = 1.47; 95% CI = 1.16-1.65), severe periodontal inflammation (PR = 1.31; 95% CI = 1.09-1.58) and dental anxiety (PR = 1.24; 95% CI = 1.03-1.49) were associated with postoperative pain after adjusting for age, gender and state and trait anxiety scores. Moreover, 46.8% of the subjects used analgesics at some time during the 48-hr follow-up period and dental anxiety was the only factor associated with postoperative analgesic use. Conclusions:Smoking, severe periodontal inflammation and dental anxiety were identified as factors associated with pain after non-surgical scaling and root planing with local anaesthesia. Dental anxiety was also a factor associated with postoperative analgesic use.
Background and Objective: A low‐grade systemic inflammatory status originating from periodontal infection has been proposed to explain the association between periodontal disease and systemic conditions, including adverse obstetric outcomes. The aim of this study was to evaluate the effect of periodontal therapy during pregnancy on the gingival crevicular fluid and serum levels of six cytokines associated with periodontal disease and preterm birth. Material and Methods: A subsample of 60 women (18–35 years of age) up to 20 gestational weeks, previously enrolled in a larger randomized clinical trial, was recruited for the present study. Participants were randomly allocated to receive either comprehensive nonsurgical periodontal therapy before 24 gestational weeks (n = 30, test group) or only one appointment for supragingival calculus removal (n = 30, control group). Clinical data, and samples of blood and gingival crevicular fluid, were collected at baseline, at 26–28 gestational weeks and 30 d after delivery. The levels of interleukin (IL)‐1β, IL‐6, IL‐8, IL‐10, IL‐12p70 and tumor necrosis factor‐α were analyzed by flow cytometry. Results: After treatment, a major reduction in periodontal inflammation was observed in the test group, with bleeding on probing decreasing from 49.62% of sites to 11.66% of sites (p < 0.001). Periodontal therapy significantly reduced the levels of IL‐1β and IL‐8 in gingival crevicular fluid (p < 0.001). However, no significant effect of therapy was observed on serum cytokine levels. After delivery, the levels of IL‐1β in the gingival crevicular fluid of the test group were significantly lower than were those in the control group (p < 0.001), but there were no significant differences between test and control groups regarding serum cytokine levels. Conclusion: Although periodontal therapy during pregnancy successfully reduced periodontal inflammation and gingival crevicular fluid cytokine levels, it did not have a significant impact on serum biomarkers.
