Objectives: The purpose of this study was to determine the factors affecting periodontal disease-related symptoms in adolescents using raw data from the 16th (2020) online survey on adolescent health. Methods: Data were collected from the survey entries, and analyzed using IBM SPSS Statistics 21.0. A multi-sample chi-square test was performed to determine periodontal disease-related symptoms according to demographic characteristics, lifestyles, exercise habits, and psychological factors. Logistic regression analysis was performed to determine factors affecting periodontal disease-related symptoms. Results: Periodontal disease-related symptoms were higher in female, high school-age adolescents, and those with lower economic status. Increased alcohol intake, having breakfast 3 days or less a week, ingesting sweet drinks and fast food three or more times a week, and zero water intake were found to have a greater effect on periodontal disease-related symptoms. Higher levels of stress, fewer hours of sleep, and feeling less healthy were also factors leading to increased periodontal disease-related symptoms. Conclusions: Adolescents have various factors that are associated with periodontal disease. A method to reduce rates of periodontal disease in adolescents should be developed, along with a school oral health education program.

Prognosis is an anticipation of the probable response to periodontal therapy and a long-term prospect for maintaining a functional dentition. Hopeless cases or cases of simple gingivitis without systemic diseases generally have little problem to establish definite prognoses. However, it might become somewhat challenging to determine their prognoses in borderline cases. A risk factor for periodontal disease may be environmental, behavioral, or biologic factors that can be defined as an occurrence has been associated with destructive periodontitis. Some risk factors are modifiable, while others cannot be modified. Modifiable risk factors are environmental or behavioral in nature in contrast non-modifiable risk factors are usually intrinsic to the individual and therefore not easily changed. In this review, we will assess the various modifiable or non-modifiable risk factors for susceptibility 10 periodontal diseases.

Periodontal disease is one of the major dental diseases. Currently, various methods are used for healing and successful regeneration of periodontal tissue damaged by periodontal disease. The periodontal ligament and alveolar bone have received considerable interest for use in periodontal tissue regeneration and induction. However, as the functions of the factors required for tooth attachment and key regulatory factors for periodontal tissue regeneration in the cementum have recently been identified, interest in cementum formation and regeneration has increased. Dental cementum forms in the late phase of tooth development because of the reciprocal regulatory interaction between cervical loop epithelial cells and surrounding mesenchymal cells, which is regulated by various gene signaling networks. Many attempts have been made to understand the regulatory factors and cellular and molecular mechanisms associated with new cementum formation. In this paper, we reviewed the study outcomes to date on the regulatory factors that induce cementum formation and regeneration, focusing on understanding the roles and functions of Wnt signaling in the regulation of cementum formation. In addition, we aimed to obtain information on the useful reciprocal regulatory factors that mediate cementum formation and regeneration through a series of molecular mechanisms.

Objectives: The purpose of the study is to investigate the influencing factors of metabolic syndrome on the periodontal disease in the Korean adults over 40 years old. Methods: The data were extracted from the Fifth National Health Nutrition Survey 2010. The subjects were adults over 40 years old. The periodontal diseases were examined by direct survey. The questionnaire consisted of the general characteristics of the subjects, oral health behavior, metabolic syndrome, and relation to periodontal diseases. CPI(community periodontal index) was measured. CPI indicates periodontal condition and classified into alveolar arch of the upper jaw and the lower jaw. A periodontal disease is defined as $CPI{\geq}3$(over 4 mm). The variables for metabolic diseases included hypertension, diabetes mellitus, dyslipidemia, and obesity measured as BMI. Results: Diabetes mellitus is closely related to periodontal diseases prevalence. Low level of HDL increase the periodontal diseases. Number of toothbrushung, use of dental floss and interdental toothbrush as for the number of toothbrushing, more than twice toothbrushing a day, and use of dental floss and interdental toothbrush reduced periodontal diseases. Conclusions: The risk factors of periodontal disease in Korean adults over 40 years old were sex, age, residence, monthly income, education level, smoking, diabetes and low HDL cholesterol.

Purpose: The National Health Insurance Service-National Sample Cohort and medical checkup data from 2002 to 2013 were used to evaluate the association between periodontal surgery for the treatment of periodontitis (PSTP) and vasculogenic erectile dysfunction (VED). Methods: Bivariate and multivariate logistic regression analyses were applied to a longitudinal retrospective database to assess the association between PSTP and VED while adjusting for the potential confounding effects of sociodemographic factors (age, household income, insurance status, health status, residence area, and smoking status) and comorbidities (diabetes mellitus, angina pectoris, cerebral infarction, and myocardial infarction). Results: Among the 7,148 PSTP within the 268,296 recruited subjects, the overall prevalence of VED in PSTP was 1.43% (n=102). The bivariate analysis showed that VED was significantly related to PSTP (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.38-2.06; P<0.001), and this was confirmed in the multivariate analysis after adjusting for sociodemographic factors and comorbidities (OR, 1.29; 95% CI, 1.06-1.58; P=0.002). Conclusions: Subjects with a history of periodontal flap surgery had a significantly higher risk of VED, after adjusting for potential confounding factors. Further studies are required to identify the key mechanisms underlying the association between severe periodontal disease and VED.

Background: This study aimed to analyze the effects of periodontal treatment and individual- and tooth-related factors on tooth extraction in people with disabilities. Methods: The Korea National Health Insurance claims data of individuals with disabilities aged 40~64 years with chronic periodontitis in 2008 were obtained. Of these, data on the disabled who underwent scaling/root plaining, subgingival curettage/periodontal surgery, or non-periodontal treatments, and data on their teeth were selected. The extraction of 716,688 teeth from 39,097 patients was tracked until 2018, and the patient- and tooth-level factors related to tooth loss were identified using a mixed-effect logistic regression analysis. Results: Data from approximately 17% of the teeth were extracted during a follow-up period of approximately 11 years. Among the tooth-level variables, scaling/root planing treatment at baseline and periodontal treatment during the follow-up period were associated with a lower risk of tooth loss (odds ratio=0.692 and 0.769, respectively, p<0.001). Non-vital teeth increased the risk of tooth loss by 3.159 times (p<0.001). Among the patient-level variables, females were less likely to have lost their teeth than males, and those with orthopedic impairment or brain lesions/mental disabilities, a higher age group, lower income level, or residents in medium/small cities or rural areas were more likely to have lost their teeth (p<0.001). Conclusion: Through approximately 11 years of follow-up, scaling or root planing, experience with periodontal treatment at least once, female sex, older age, lower income, smaller residential areas, type of disability, and pulp vitality were found to be associated with tooth loss in individuals with disabilities aged 40~64 years with chronic periodontitis. To prevent tooth loss in individuals with disabilities, it is necessary to establish a dental treatment plan that considers the timing of periodontal treatment and the characteristics of the patient and teeth.

Periodontitis is characterized by gingival inflammation and results in periodontal pocket formation with loss of the supporting alveolar bone and connective tissue around the teeth. Therapeutic modalities should therefore aim not only at eliminating the gingival inflammatory process and preventing the progression of periodontal disease but also at reestablishing and regenerating the periodontal tissue previously lost to the disease. To achieve periodontal regeneration, progenitor cells must migrate to the denuded root surface, attach to it, proliferate and mature into an organized and functional fibrous attachment apparatus. Likewise, progenitor bone cells must also migrate, proliferate, and mature in conjunction with the regenerating periodontal ligament. Significant advances have been made during the last decade in understanding the factors controlling the migration, attachment and proliferation of cells. A group of naturally occuring molecules known as polypeptide growth factors in conjunction with certain matrix proteins are key regulators of these biological events. Of these, the fibroblast growth factor(FGF), platelet-derived growth factor(PDGF) , insulin like growth factor(CIGFs), transforming growth factor(TGFs), epidermal growth factor(EGF) and bone morphogenetic growth factor(BMPs) apper to have an important role in periodontal wound healing. The purpose of this study was to determine the effects of BMP on periodontal ligament cells. Human periodontal ligament cells were cultured from extracted tooth for non-periodontal reason. Cultured periodontal ligament cells were treated with BMP. Cellular activities were determined by MTT(3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay and ALP(alkaline phosphatase) activity. The results were as follows ; Regardless of cultured time, cellular activities were stimulated by BMP. Also, BMP greatly increased alkaline phosphatase(ALP) in periodontal ligament cells. These results suggest that BMP not only have no cytotoxic effect on periodontal ligament cells, but also have osteogenic stimulatory effect on periodontal ligament cells.

As long as the prognosis of teeth remains a matter of concern, the endodontic-periodontal relationship will be considered a challenge for the clinician. Many etiologic factors, including bacteria, fungi, and viruses, plus other contributing factors, such as trauma, root resorptions/perforations, and dental malformations, play a role in the co-occurrence of endodontic and periodontal lesions. Whatever the cause, a correct diagnosis on which to base the treatment plan is the key to successful maintenance of the tooth. This article reports the successful endodontic management of a furcation lesion in a mandibular molar that was nonresponsive to a previous periodontal surgical graft. The case had presented a diagnostic challenge for the clinicians, and this article reviews the key points that can lead to a correct diagnosis and treatment planning.
