Abstract

Background: Recent studies suggest that chronic periodontitis (CP) and type2 diabetes mellitus (T2DM) arebidirectionally associated. Analysis of saliva as a mirror of oral and systemic health could allow identification of αamylase (α-Am) and albumin (A1) antioxidant system markers to assist in the diagnosis and monitoring of bothdiseases. The present study aims at comparing the clinical periodontal parameters in chronic periodontitis patientswith poorly or well controlled Type 2Diabetes Mellitus, salivary α-Am, A1, flow rate (FR) and pH then correlatebetween biochemical, physical and clinical periodontal parameters of each study and control groups.Materials and Methods: 80 males, with an age range of (35-50) years were divided into four groups, (20 subjectseach): two groups had well or poorly controlled Type 2Diabetes Mellitus both of them with chronic periodontitis,group of patients with only chronic periodontitis and control group with healthy periodontium and systemicallyhealthy. From all subjects unstimulated whole salivary samples were collected to measure FR, pH, Al and α – Am,then clinical periodontal parameters (plaque index, gingival index, bleeding on probing, probing pocket depth andclinical attachment level)were recorded.Results: Patients had chronic periodontitis with poorly controlled Type 2Diabetes Mellitus demonstrated the highestmedian values of all clinical periodontal parameters and highest increase in levels of salivary α-Am and Al withlowest median values of FR and pH, in addition to the highly significant differences among the study and controlgroups regarding biochemical and physical parameters. Positive correlations were revealed between α-Am with Aland both of them with all clinical periodontal parameters but, they were negative with FR and pH.Conclusion: Patients with poor glycemic control had more severe periodontal tissue break down with decrease in FRand pH also obvious increase in levels of A1 and α- Am so, these biochemical markers will provide an objectivephenotype to allow practitioners for early diagnosis, which is essential for improved prognosis and effective delay ofclinical complications associated with chronic periodontitis and DM and an important strategy to lower theincidence of both diseases world wide

Abstract

Background: Type 2 diabetes mellitusand chronic periodontitis hold a close relationship that has been the focus ofmany researches. Currently there is an appreciation to the role of adipose tissue-derived substances "the adipokines"in immune-inflammatory responses; also, there is an interest in using the simple non-invasive saliva in diagnosing andlinking oral and general health problems. The current study aims to determine the periodontal health status in thechronic periodontitis patients with and without poorly or well controlled type 2 diabetes mellitus, measure the salivarylevels of two adipokines "leptin and resistin", pH and flow rate and then correlate between these clinical periodontal,biochemical and physical parameters in each study and control groups.Materials and Methods: Seventy five males were recruited for the study, with an age range of (35-50) years. Thesubjects were divided into four groups: two non-diabetic groups: one of them with healthy periodontium andsystemically healthy (Control, 15 subjects) and the other with chronic periodontitis (20 patients) and two type 2diabetic groups: well controlled (20 patients) and poorly controlled (20 patients) both of them with chronicperiodontitis.Unstimulated whole salivary samples were collected from all of the participants; salivary flow rate andpH were measured and then biochemically analyzed for assessment of resistin and leptin levels.Clinical periodontalparameters included: the plaque index, the gingival index, the bleeding on probing, the probing pocket depth andthe clinical attachment level had been recorded for all subjects at four sites per tooth except for the third molars.Results: The results of clinical periodontal examination revealed that the group of chronic periodontitis with poorlycontrolled type 2 diabetes mellitus had the worst periodontal health status. The biochemical analysis demonstratedthat the lowest level of salivary leptin was foundin the chronic periodontitis with poorly controlled type 2 diabetesmellitus group. In addition, the highest level of salivary resistin was demonstrated in chronic periodontitis with wellcontrolled type 2 diabetes mellitus group. When the salivary flow rate and pH were measured, it was found that theywere decreased in the study groups as compared to the control group. A non-significant moderate negativecorrelation between salivary leptin with pH in the control group was found. While, salivary resistin demonstrated ahigh significant moderate positive correlation with the gingival index in the non-diabeticchronic periodontitis groupand a non-significant moderate negative correlation with salivary flow ratein the control group. Finally, the studyfound that the correlation between salivary leptin and resistin was non-significant weak negative in each of the studyand control groups.Conclusion: It can be concluded that poorly controlled type 2 diabetic patients have more periodontal tissuedestruction and less salivary flow rate than well controlled type 2 diabetic patients and non-diabetic patients all ofthem with chronic periodontitis. Salivary Resistin and Leptin hormones may be useful biochemical markers ofperiodontal tissue destruction and this will provide better opportunities in early diagnosis, monitoring and efficientmanagement of periodontal diseases and T2DM.

Abstract

Among natural food sources with antimicrobial activities, gingerrhizome has been used as widely grown food spices and medicinalcrops for centuries. Furthermore, it possess antifungal andantioxidant properties due to the phenols – related constituents(gingerols) that constrain the growth of many Gram positive andGram negative bacteria including some periodontal bacteria. TheActinomycetem comitans is a portion of the normal microbiota innumerous healthy individuals but is also a major etiological agentin some aggressive and chronic types of periodontitis.The present study was conducted to test the effect of aqueous andalcoholic ginger extracts on the growth of Aggregatibacteractinomycetem comitans in comparision to 0.2% chlorohexidinegluconate mouth wash and distilled water in vitro, determinationof ginger extracts minimum inhibitory concentration andminimum bactericidal concentration and detection of activeingredients of ginger extracts by using the high-performance liquidchromatography as well as chemical elements.

Abstract

Background: Biologically active substances, such as Cathepsin B (CAB) which is a lysosomalcystein protease may beinvolved in periodontal metabolism in the degradation of organic bone matrix containing collagen fibers in responseto mechanical stress from orthodontic appliance. The aims of study were to determine and compare salivary levelsof CAB, pH as well as clinical periodontal parameters (Plaque index PLI and gingival index GI) with differentorthodontic force magnitudes at different time intervals.Materials and methods: A twenty-four patients (both gender) with age range (17-23) years had Angle's Class IIdivision 1 malocclusion with GI <0.5 enrolled in this study. The level of salivary CAB and pH, in addition to the clinicalperiodontal parameters (PLI and GI) were measured before (baseline), 1 hour (1H), 1 day (1D), 1week (1W), 2 weeks(2W) and 3 weeks (3W) after fixed orthodontic appliance placement with different forces applied to the teeth (F1 (40gm), F2 (60 gm) and F3 (80 gm)).Results: The highest mean concentration of salivary CAB was (12.057) at F1 in 1D visit with highly significantdifferences among the visits as well as among the forces (p≤0.05). Weak correlations were revealed between all pairsof forces as well as between each visit with the baseline visit about salivary CAB except the strong negativecorrelations between F1 with F3 at 3W and baseline with 3W visits at F3. Maintenance of good oral hygiene duringthe study period demonstrated that the highest mean values of PLI and GI were (0.2) and (0.25) respectively, inaddition to the non-significant differences regarding pH among the visits.Conclusion: The concentration of salivary CAB was increased following fixed orthodontic appliance insertion. Thevery light continuous orthodontic force could produce significant increase of this enzyme activity and give enougheffectiveness to produce tooth movement as compared to the higher forces

Abstract

ovary syndrome (PCOS) and periodontal diseases arecommon chronic inflammatory disorders. PCOS is a complicatedcondition affects overall health and causes broad spectrumchanges that affect periodontal health status. Available evidencesuggests that oxidative stress might comprise a link for theassociation between periodontal diseases and components of themetabolic syndrome. Both homocysteine (Hcy) and nitric oxide(NO) are considered to reflect the strength of oxidative stress. Theaims of the study were to compare the periodontal health conditionamong the study groups (gingivitis, gingivitis +PCOS, chronicperiodontitis (CP) and CP + PCOS group) by measuring theclinical periodontal parameters (Plaque Index (PLI), GingivalIndex (GI), Bleeding on Probing (BOP), Probing Pocket Depth(PPD) and Clinical Attachment Level (CAL), and measure serum(Hcy) and (NO) and compare their levels between study groups ,then correlate between these parameters with each other and withclinical periodontal parameters in order to determine the effect ofPCOS on periodontal health status and levels of serumHcy and NO.
