It has been reported that there is a relationship between a single-nucleotide polymorphism (SNP) in the promoter region of the CD14 gene at position -159 (C-->T) and infectious diseases. The aim of the present study was to test the hypthesis that expression of this SNP correlates with periodontal disease in a Japanese population. The CD14 genotype was determined in 163 subjects with periodontitis and in 104 age- and gender-matched control subjects without periodontitis. The genotype distribution and allele frequency within the periodontitis patients were not significantly different from those of control subjects. There was, however, a significant difference in the genotype distribution between young patients (< 35 yrs) and older patients (>/==" BORDER="0"> 35 yrs). These findings suggest that CD14 -159C/T polymorphism is not related to the development of periodontitis in a Japanese population, but that, within the periodontitis subjects, expression of the SNP may be related to early disease activity.

Prevalence of periodontal diseases in patients with  diabetes mellitus (An observational study     at internal medicine polyclinic in  Dr.  Sardjito General Hospital). Diabetes Mellitus (DM) is a  chronic disease    with an increasing prevalence and causes complications. The most frequent complication found in the oral cavity of patients with diabetes mellitus is periodontal diseases is characterized by the loss of tissue attachment. There have been numerous studies on the association of DM with periodontal diseases but there has not been any data on the prevalence of periodontal diseases in diabetic group, especially in Yogyakarta and Central Java. Dr. Sardjito General Hospital is a referral hospital in DIY and Central Java, so this study is expected to provide a picture regarding the level of periodontal tissue health among people in Yogyakarta and Central Java. This research was an observational study, involving 36 patients with DM according to criteria of the subjects: suffering from type 2 diabetes, being cooperative  and willing to sign an informed consent. The controlled variables: being 40 – 60 years of age, having good oral hygiene (OHI) according to Green and Vermillion, taking neither antibiotics nor anti-inammatory drugs in the last 3 months, not having a history of other systemic diseases. Oral hygiene exams were carried out, followed by examination using probe WHO to determine if there is CAL. The data were presented descriptively. The results showed that the prevalence of periodontal diseases in patients with DM at Internal Medicine Polyclinic in Dr. Sardjito General Hospital is 88.24% with a mean of CAL distance of 4.6 mm. The conclusion of this study is that the prevalence of periodontal diseases in patients with DM is high although the oral hygiene status is good. ABSTRAKDiabetes Mellitus (DM) adalah penyakit kronis menahun dengan prevalensi yang semakin meningkat dan menimbulkan komplikasi.

One of the regenerative periodontal treatments for infrabony pocket is open flap debridement (OFD) with the addition of growth factor derived from platelet concentrate. Advanced platelet-rich fibrin (A-PRF) is a further development of plateletrich fibrin (PRF) with a lower centrifugation speed (1,500 rpm, 14 minutes). The purpose of this study was to examine the differences in periodontal tissue regeneration after the application of A-PRF and PRF in the treatment of infrabony pockets evaluated from probing depth (PD), relative attachment loss (RAL), and alveolar bone height. The samples were taken from 20 infrabony pockets divided into 2 groups: 10 subjects were treated with OFD+A-PRF and OFD+PRF on the remaining subjects. Probing depth (PD) and relative attachment loss (RAL) measurement were performed on days 0, 30, and 90. Bone height measurements were performed using CBCT X-rays on days 0 and 90. The results showed that PD and RAL reduction in the group of OFD+A-PRF was significantly greater than that in the OFD+PRF group. Bone height reduction in both groups showed no difference. The conclusion obtained from this study is A-PRF application enhances periodontal tissue regeneration by generating greater probing depth and relative attachment loss reduction compared to PRF, as well as an increase in bone height similar to in the treatment of infrabony pockets.

Ozonated olive oil has been widely used as a local infection therapy to overcome bacterial resistance from antibiotics with systemic administration. However, the disadvantage of systemic antibiotics is it cannot be used in large doses for local infection therapy. Periodontitis is an infectious disease that causes alveolar bone damage. In the periodontitis healing process, osteoblasts and angiogenesis play essential roles in bone regeneration. The study aims to determine the effect of topical application ozonated olive oil to osteoblasts number and angiogenesis of alveolar bone in periodontitis healing process using in vivo study. 32 Sprague Dawley rats were divided into two groups: the treatment and placebo groups, 16 rats in each group. The induction of periodontitis was performed by ligating lower incisor with silk ligature for seven days. The treatment group received ozonated olive oil, and the placebo group received 1 % of CMC-Na twice a day. Four rats from each group were necropsied on day 3, 5, 7, and 14 and then processed into histological sample preparations by hematoxylin-eosin staining and counted the number of osteoblast and blood vessels. All collected data were analyzed using two-way ANOVA and posthoc LSD test. The average number of osteoblasts, blood vessels in the treatment group were significantly higher than the placebo group (p <0.05) either on day 3, 5, 7, and 14. Results showed the ozonated olive oil increase the regeneration of alveolar bone in the periodontitis healing process in Sprague Dawley. Therefore ozonated olive oil has the effect of periodontal tissue regeneration.

Background: Periodontitis causes an increased receptor activator level in the nuclear factor-κβ ligand (RANKL), which is one of the inflammatory mediators that plays a role in osteoclastogenesis. The open flap debridement (OFD) technique is the preferred treatment when accompanied by regenerative periodontal treatment using guided tissue regeneration (GTR) and guided bone regeneration (GBR). Carbonated hydroxyapatite is a GBR material that serves as a scaffold and has strong osteoconductive properties for bone regeneration. Propolis is natural product that can decrease osteoclastogenesis in periodontitis by decreasing the RANKL expression. Purpose: To investigate the RANKL expression after open flap debridement by applying carbonated hydroxyapatite to 10% propolis in the alveolar bone of rabbits. Methods: Nine induced-periodontitis rabbits (Oryctolagus cuniculus) were divided into three treatment groups of Group A OFD, Group B OFD followed by the application of carbonated hydroxyapatite, and Group C OFD followed by application of 10% propolis-carbonated hydroxyapatite. Each group was selected one to euthanised on the seventh, 14th and 28th day, respectively, and prepared using histology slides. The data was analysed using a two-way ANOVA followed by a post-hoc LSD test (p<0.05). Results: The RANKL expression in each group showed significant differences (p=0.00; p<0.05) on the seventh, 14th and 28th day. The post-hoc LSD test showed that the RANKL expression in the treatment group with carbonated hydroxyapatite-10% propolis had significant differences (p<0.05) in the intergroup analysis at different time points. Conclusion: Combining 10% propolis with carbonated hydroxyapatite in OFD treatment can decrease the RANKL expression in a rabbit’s alveolar bone.

Open flap debridement (OFD) is an invasive therapy for chronic periodontitis with pocket 5 mm or more. However, it is difficult to achieve regeneration and new attachment with this therapy. Periodontitis starts to add growth factors and local drugs delivery as host modulation therapy. Advanced-PRF (A-PRF) contains more growth factor than PRF which plays a role in promoting fibroblast proliferation, reepithelization, extracellular matrix production, and endothelial cell migration. 1.2% rosuvastatin gel (RSV) is a local delivery drug with a pleiotropic effect that can modify host response to promoting BMSCs, BMP-2, OPG, ALP, RANKL, and osteoblasts. This study aimed to examine the effect of the application of A-PRF+RSV in OFD therapy of which the parameters were probing depth (PD), relative attachment loss (RAL), and alveolar bone height. The study samples consisted of 24 periodontal pockets which were divided into 2 groups of 12 pockets each, namely A-PRF+RSV for group 1 and PRF+RSV for group 2. Clinical evaluations were carried out on baseline, day-30, and day-90 for PD and RAL, and on baseline and day -90 for alveolar bone height. Data of PD and RAL reduction were analyzed with non-parametric test Mann-Withney, while data of reduction of alveolar bone height were analyzed with parametric Independent-T test. Group 1 obtained a statistically more significant result in reducing PD, RAL, and alveolar bone height compared to group 2 (p<0.05) To conclude, the application of A-PRF and 1.2% rosuvastatin gel in OFD procedure promotes a higher PD and RAL reduction and alveolar bone height increase than the application of PRF coupled with 1.2% rosuvastatin gel.

Fiber Reinforced Composite (FRC) menggunakan E-glass fiber dental dalam bidang kedokteran gigi telah banyak diaplikasikan secara klinis, salah satunya dalam aplikasi splinting periodontal.

Kesimpulan penelitian ini adalah orientasi dan volumetrik glass fiber non dental memberikan pengaruh terhadap peningkatan kekuatan perlekatan geser FRC.

Carbonated hydroxyapatite is ideal as a bone graft material because it has similar organic matters to the bone, excellent osteoconductive properties, and good biodegradation in the body. Hydroxyapatite contains the risk of being contaminated by bacteria called Porphyromonas gingivalis (P. gingivalis) in the oral cavity because it has no vascularization, therefore, facilitating adhesion of bacteria, and when applied in the oral cavity, it may cause an infection that then inhibits healing. Thus, it is necessary to use a material that has an antibacterial effect with low potential of causing resistance to treat the postsurgical infection properly. Propolis has antibacterial, antiviral, antifungal, antitumor, and immunomodulatory activities. Propolis contains a large number of flavonoids and phenols. The phenol compound in propolis is usually called caffeic acid phenethyl ester (CAPE), and it has a good antibacterial property. The study aims to evaluate the antibacterial effect of carbonated hydroxyapatite when immersed with different propolis concentrations of 2.5%, 5%, 7.5%, and 10% for 24 h and to measure the zone of inhibition against P. gingivalis. The Kruskal–Wallis test resulted in p = 0.00 (p < 0.05), indicating that there were significant differences among the test groups. The data processing was followed by Mann–Whitney U-test, and the results showed a significant difference in the group of carbonated hydroxyapatite-10 % propolis compared with the other groups. Inhibition zone of carbonated hydroxyapatite that immersed with propolis 10% showed the largest mean of diameters zone of inhibition.
