Antimicrobial photodynamic therapy acts as a beneficial adjunct to SRP in non-surgical treatment and management of chronic periodontitis in short-term. Further studies are required to assess the long-term effectiveness of aPDT.

The aim of this systematic review was to investigate whether antimicrobial photodynamic therapy (aPDT) as either a primary mode of treatment or an adjunct to non-surgical treatment was more effective than scaling and root planing (SRP) alone in treating chronic periodontitis in terms of clinical attachment level (CAL) gain and probing depth (PD) reduction. The focused question was developed using the Patient, Intervention, Comparison, and Outcome (PICO) format, and two authors independently searched the Medline, EMBASE, Cochrane Library, Web of Science, Google Scholar, and Scopus databases for relevant studies from January 2008 to December 2016. Twenty studies included in this systematic review were randomized clinical trials (RCTs) or quasi-RCTs of aPDT compared to placebo, no intervention, or non-surgical treatment in an adult population. Basic study characteristics, photosensitizing agents and wavelengths used in aPDT, frequency of aPDT application, effect of aPDT on clinical parameters, antimicrobial effect of aPDT in chronic periodontitis, effect of immunological parameters following aPDT and patient-based outcome measures were collected from the studies. Although there was a wide range of heterogeneity in the included studied, they all indicated that aPDT has the potential to be an effective adjunct in the treatment of chronic periodontitis. Long-term, multicenter studies with larger sample sizes are needed before aPDT can be recommended as an effective treatment modality.

There is inconclusive evidence about the link between the severity and prevalence of periodontitis in obese adults. Therefore, this systematic review aims to explore the possibility of significant evidence on the association between obesity and periodontitis and to determine the necessity to consider obesity as a risk factor for periodontitis. We followed the PRISMA protocol, and studies that met the eligibility criteria were included in this review. The risk of bias in individual studies was also evaluated. This review included 15 observational studies (9 cross-sectional studies, 2 case-control, and 4 cohort studies). The total study subjects from these studies were 6603 (males = 3432; females = 3171). Most studies showed a significant association between obesity and periodontitis. Among these studies, a few showed obese females to be at a higher risk, and one study found no association between obesity and periodontal disease at all. Based on the evidence obtained from this review, the body mass index (BMI) should be routinely assessed in patients to assess the risk for periodontal disease and to offer personalized management of periodontitis. Based on the findings of this review, we recommend the need to initiate awareness among clinicians and implement dental hygiene care prevention measures for obese patients.

Objectives To determine the prevalence of chronic periodontitis and its determinants among patients in the Aseer Region of KSA. Methods A total of 1000 consecutive new female patients between 25- to 75-years of age were screened for the presence of any periodontal disease. The various demographic characteristics of the study participants included age, educational level, occupation, presence of diabetes mellitus, family history of periodontal disease, and oral hygiene practices per subject were recorded. The parameters addressing periodontal prevalence and severity were also recorded. Results Of these patients, 457 were found to have evidence of periodontal disease. These patients were considered for a further detailed periodontal examination. The chi-square test for goodness of fit showed that 46.6% have localized chronic gingivitis while 2.2% have generalized chronic gingivitis. Localized chronic periodontitis ranged from 4.2% to 12%, whereas generalized chronic periodontitis varied from 3.1 to 14.7%. The non-parametric Kruskal–Wallis chi-square statistics showed that factors such as age, education, occupation, infrequent last dental visit, presence of diabetes mellitus and bleeding on probing were significant risk determinants for periodontal disease in the selected cohort. Conclusion The majority of the population showed the presence of localized chronic gingivitis. Age, education, occupation, infrequent dental visits and presence of diabetes mellitus are significant risk determinants for the occurrence of chronic periodontitis. Information concerning individual risk for developing periodontal disease should be carefully evaluated for proper patient management and for better overall general health.

Background/purposeSalivary markers of bone turnover are useful biomarkers for screening patients advanced periodontal diseases with alveolar bone loss. Hence, the purpose of this study was to determine the diagnostic accuracy of deoxypyridinoline-containing degradation fragment of the C-terminal telopeptide region of type I collagen (CTX), Osteocalcin (OC) and Osteonectin (ON) in identifying patients with alveolar bone loss (BL) due to periodontitis.Materials and methodSalivary levels of CTX, OC and ON were evaluated in ninety patients (group I, II and III with healthy, periodontitis without Type2 diabetes mellitus-T2DM and periodontitis with T2DM respectively). Group III was included since T2DM is very common among patients attending our clinics. Bleeding on probing (BOP), probing pocket depth (PPD) and BL were recorded for these patients.ResultsThe concentrations of salivary CTX, OC, and ON were higher in subjects with periodontitis than in controls. Significant correlations were found between these biomarkers and periodontal parameters. CTX, OC, and ON could discriminate between healthy (group I) and diseased (group II & III) regarding BL with excellent sensitivity (90.2–100%) and good specificity (62.1–96.6%). ROC curve gave excellent discrimination regarding BL (AUC: 0.926–0.958) and PPD (AUC: 0.904–0.915). However, none of the cut-off values gave good discrimination regarding BOP.ConclusionIt can be concluded that CTX, OC, and ON correlated well with BL and PPD. Among the three biomarkers, ON at 81.80 ng/ml gave the best discrimination for presence or absence of bone loss.

Objective: The relevance of growth determination in orthodontics is driving the search for the most precise and least invasive way of tracking the pubertal growth spurt. Our aim was to explore whether minimally invasive salivary estimation of biomarkers Insulin-like growth factor (IGF-1) and Insulin-like growth factor binding protein-3 (IGFBP-3) could be used to estimate skeletal maturity for clinical convenience, especially in children and adolescent age groups. Materials and Method: The cross-sectional study was conducted on 90 participants (56 girls and 34 males) with ages ranging from 6 to 25 years. Each subject’s hand-wrist radiograph was categorized based on skeletal maturity, and saliva samples were estimated for IGF-1 and IGFBP-3 using the respective ELISA kits. Kruskal–Wallis nonparametric ANOVA was applied to compare different skeletal stages. Results: The study demonstrated low salivary IGF-1 levels at the prepubertal stage, with increase during pubertal onset and peak pubertal stage followed by a decline during pubertal deceleration to growth completion. Spearman’s correlation coefficient demonstrated a strong positive association (r = 0.98 p < 0.01) between salivary IGF/IGFBP-3 ratio and different stages of skeletal maturity. Conclusion: Salivary IGF-1, IGFBP-3, and IGF/IGFBP-3 ratio could serve as a potential biochemical marker for predicting the completion of skeletal maturity.
