Plaque-induced periodontal diseases occur in response to the accumulation of dental plaque. Disease manifestation and progression is determined by the nature of the immune response to the bacterial complexes in plaque. In general, predisposing factors for these periodontal diseases can be defined as those factors which retain or hinder the removal of plaque and, depending upon the nature of the immune response to this plaque, the disease will either remain stable and not progress or it may progress and result in chronic periodontitis. In contrast, modifying factors can be defined as those factors that alter the nature or course of the inflammatory lesion. These factors do not cause the disease but rather modify the chronic inflammatory response, which, in turn, is determined by the nature of the innate and adaptive immune responses and the local cytokine and inflammatory mediator networks. Chronic inflammation is characterized by vascular, cellular and repair responses within the tissues. This paper will focus on how common modifying factors, such as smoking, stress, hormonal changes, diabetes, metabolic syndrome and HIV/AIDS, influence each of these responses, together with treatment implications. As treatment planning in periodontics requires an understanding of the etiology and pathogenesis of the disease, it is important for all modifying factors to be taken into account. For some of these, such as smoking, stress and diabetic control, supportive health behavior advice within the dental setting should be an integral component for overall patient management.
Dental implants are regularly placed in patients with a history of periodontitis, even though peri-implant tissues are susceptible to the same host-modulated plaque-induced factors that initiate and sustain periodontitis. This article endeavors to clarify the evidence regarding the history of periodontitis as a risk factor for implant success and survival, and the role of supportive periodontal therapy in maintaining implants for individuals with a history of periodontitis.
Aims: Patient-reported outcomes have attracted interest as there has been a shift from clinician-centric endpoints. This qualitative study aimed to develop an understanding of the psychosocial impact of periodontitis and its treatment. Materials and methods: Fourteen adults were asked to document their experiences of untreated periodontitis and non-surgical periodontal therapy at a university clinic, using written or audio-recorded diaries. The diary data were then used as a framework for semi-structured qualitative interviews, conducted at the completion of initial non-surgical treatment. Inductive thematic content data analysis was employed. Results: Three themes illustrated the detrimental impact of periodontitis: "concealment," "having a guilty conscience" and "patient comfort as paramount." These were related to a core underlying concept, "progression to a more positive outlook," which described a distinct shift in participants' attitudes and optimism after their periodontal treatment. Despite finding treatment unpleasant, the participants described profound positive influences on their social well-being, self-esteem, mood, work, relationships and outlook. Conclusions: This study illustrated the broad psychosocial impact of periodontitis. The findings suggest that the benefits of periodontal treatment extend beyond improvements in traditional biomedical indicators to those which are more relevant and desirable to patients.
In this paper, we consider personalized periodontics from a public health perspective. Periodontitis is an under-acknowledged and important public health problem, and there has long been interest in identifying and treating those who are at high risk of developing this disease. Although susceptibility/risk-assessment tools in periodontology are currently in their early stages of development, personalized periodontics is increasingly becoming a realistic approach. At the population level, however, personalized periodontics is not an effective way of improving periodontal health because it would target only those who seek help or are able to access care. The occurrence of periodontitis in populations is socially patterned, with those of lower socio-economic position having poorer periodontal health and being far less likely to seek care. There is the potential for social inequalities actually to worsen as a result of personalized periodontics. In most health systems, personalized periodontics is likely to be accessible only to the social strata for whom it is affordable, and those with the greatest need for such an intervention will remain the least likely to be able to get it. Thus, personalized periodontics is likely to be a niche service for a small proportion of the adult population. This is at odds with the public health approach.
The diabetes-periodontitis association in the NZ population remains unclear. This study demonstrates that the determination of the strength of a putative association is method dependent.
