Aggressive Periodontitis is one of periodontal disease that generally affects individuals less than 30 years old, with a rapid attachment loss and alveolar bone destruction. Special features of the disease are affected incisors and first molars with symmetrical bilateral destruction. The purpose of this study was to determine the prevalence and characteristics of Aggressive Periodontitis at Student Clinics, Faculty of Dentistry Padjadjaran University on May to July 2010. Based on accidentally sampling, 415 new patients at Dental and Oral Hospital, Faculty of Dentistry Padjadjaran University and Dental and Oral Polyclinic at RSUP dr. Hasan Sadikin Bandung participated in this study. Each subject filled out the questionnaire and did a clinical examination. Patients with attachment loss ≥ 4 mm were referred for radiographic and microbiologic examination to support the diagnosis. The results showed that there were 13 patients who have the diagnostic criteria of Aggressive Periodontitis. Nine patients were diagnosed as Localized Aggressive Periodontitis, and 4 patients as Generalized Aggressive Periodontitis. It is concluded that the prevalence of Aggressive Periodontitis was 3.13%, and indicated low prevalence. Characteristics of Localized Aggressive Periodontitis patients were female in 20-29 age range, whereas characteristics of Generalized Aggressive Periodontitis patients were male in 30-39 age range.

Experimental Periodontitis

Although there is a clear relationship between the degree of obesity and periodontal disease incidence, the mechanisms that underpin the links between these conditions are not completely understood. Understanding that myeloid-derived suppressor cells (MDSCs) are expanded during obesity and operate in a context-defined manner, we addressed the potential role of MDSCs to contribute toward obesity-associated periodontal disease. Flow cytometry revealed that in the spleen of mice fed a high-fat diet (HFD), expansion in monocytic MDSCs (M-MDSCs) significantly increased when compared with mice fed a low-fat diet (LFD). In the osteoclast differentiation assay, M-MDSCs isolated from the bone marrow of HFD-fed mice showed a larger number and area of osteoclasts with a greater number of nuclei. In the M-MDSCs of HFD-fed mice, several osteoclast-related genes were significantly elevated when compared with LFD-fed mice according to a focused transcriptomic platform. In experimental periodontitis, the number and percentage of M-MDSCs were greater, with a significantly larger increase in HFD-fed mice versus LFD-fed mice. In the spleen, the percentage of M-MDSCs was significantly higher in HFD-fed periodontitis-induced (PI) mice than in LFD-PI mice. Alveolar bone volume fraction was significantly reduced in experimental periodontitis and was further decreased in HFD-PI mice as compared with LFD-PI mice. The inflammation score was significantly higher in HFD-PI mice versus LFD-PI mice, with a concomitant increase in TRAP staining for osteoclast number and area in HFD-PI mice over LFD-PI mice. These data support the concept that M-MDSC expansion during obesity to become osteoclasts during periodontitis is related to increased alveolar bone destruction, providing a more detailed mechanistic appreciation of the interconnection between obesity and periodontitis.

Palmoplantar Hyperkeratosis

Haim-Munk syndrome is an extremely rare autosomal recessive disorder characterized clinically by palmoplantar hyperkeratosis, aggressive periodontitis with severe alveolar bone destruction, onychogryphosis, pes planus, arachnodactyly, and acro-osteolysis. Consanguinity seems a notable prerequisite. The aim of this study was therefore to report one case of this syndrome and to focus on the periodontal manifestations, in order to attract the attention of dental clinicians to this rare anomaly.

The Relationship

Periodontal disease is an inflammatory disease caused by pathogenic oral microorganisms that leads to the destruction of alveolar bone and connective tissues around the teeth. Although many studies have shown that periodontal disease is a risk factor for systemic diseases, such as type 2 diabetes and cardiovascular diseases, the relationship between nonalcoholic fatty liver disease (NAFLD) and periodontal disease has not yet been clarified. Thus, the purpose of this review was to reveal the relationship between NAFLD and periodontal disease based on epidemiological studies, basic research, and immunology. Many cross-sectional and prospective epidemiological studies have indicated that periodontal disease is a risk factor for NAFLD. An in vivo animal model revealed that infection with periodontopathic bacteria accelerates the progression of NAFLD accompanied by enhanced steatosis. Moreover, the detection of periodontopathic bacteria in the liver may demonstrate that the bacteria have a direct impact on NAFLD. Furthermore, Porphyromonas gingivalis lipopolysaccharide induces inflammation and accumulation of intracellular lipids in hepatocytes. Th17 may be a key molecule for explaining the relationship between periodontal disease and NAFLD. In this review, we attempted to establish that oral health is essential for systemic health, especially in patients with NAFLD.

Periodontal disease is a common chronic adult condition. The bacteriumPorphyromonas gingivalishas been implicated in the aetiology of this disease, which causes destruction of the connective tissue and bone around the root area of the tooth. It has been observed that invadingP. gingivalisbacteria trigger the release of cytokines such as interleukin 8 and tumour necrosis factor α, leading to elevated numbers and activity of polymorphonucleocytes (PMN). As a result of stimulation by bacterial antigens, PMN produce the reactive oxygen species (ROS) superoxide via the respiratory burst as part of the host response to infection. Patients with periodontal disease display increased PMN number and activity. It has been suggested that this proliferation results in a high degree of ROS release, culminating in heightened oxidative damage to gingival tissue, periodontal ligament and alveolar bone. Antioxidant constituents in plasma have been well-documented, being chiefly ascorbate, albumin and urate, and these are known to display sensitivity to dietary antioxidant intakes. The concentration of antioxidants in saliva does not appear to mirror those of plasma. The extent of dietary influence upon salivary antioxidant status is unclear. Urate is the predominant salivary antioxidant, with albumin and ascorbate providing minor contributions. Previous research has found reduced salivary antioxidant activity in patients suffering from periodontal disease. An improved understanding of the role antioxidants play in periodontitis, and the influence of nutrition on antioxidant status, may lead to a possible nutritional strategy for the treatment of periodontal disease.
