Smoking and periodontal microorganisms

Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Takashi Hanioka, Manabu Morita, Tatsuo Yamamoto, Koji Inagaki, Pao-Li Wang, Hiroshi Ito, Toshiya Morozumi, Toru Takeshita, Nao Suzuki, Hideo Shigeishi, Masaru Sugiyama, Kouji Ohta, Toru Nagao, Nobuhiro Hanada, Miki Ojima, Hiroshi OgawaSummaryResolution of dysbiosis following treatment for periodontal disease and tobacco dependence has been reported in longitudinal intervention studies. In the present report, we evaluated the biological findings regarding the effect of smoking on the periodontal microbiome. A standardized electronic search was conducted using MEDLINE; overall, 1099 papers were extracted. Studies that addressed the relationship between tobacco and periodontal pathogens were included. Finally, 42 papers were deemed appropriate for the present review. Functional changes in periodontal pathogens exposed to nicotine and cigarette smoke extract support the clinical findings regarding dysbiosis of the subgingival microbiome. Dysbiosis of the periodontal microbiome was presented in smokers regardless of their periodontal condition (healthy, gingivitis, or periodontitis) and remained significant only in smokers even after the resolution of experimentally-induced gingivitis and following reduction of clinical signs of periodontitis with non-surgical periodontal treatment and over 3 months post-therapy. Based on these findings, smoking cessation in periodontitis patients i...

Iole Vozza The aim of the present study is to verify the knowledge of risks and complications of oral piercings, and to observe the main complications associated with piercings, using a sample from central Italy of patients wearing intraoral piercings. Through piercing and tattoo studios selected randomly in Rome, Latina and Campobasso, and a tattoo and piercing convention in Latina, a group of 387 individuals with oral piercings were selected and asked to complete an anonymous questionnaire. After filling in questionnaires, 70 individuals of the 387 selected agreed to be visited to allow the observation of the integr...

CONCLUSIONS: As a result of this study, CF coexists increasing pro-inflammatory and decreasing anti-inflammatory response locally. Due to increasing pro-inflammation, CF patients should be followed-up more often than non-CF children. PMID: 31927460 [PubMed - as supplied by publisher]

Neutrophils are amongst the most abundant immune cells within the periodontal tissues and oral cavity. As innate immune cells, they are first line defenders at the tooth-mucosa interface, and can perform an array of different functions. With regard to these, it has been observed over many years that neutrophils are highly heterogeneous in their behavior. Therefore, it has been speculated that neutrophils, similarly to other leukocytes, exist in distinct subsets. Several studies have investigated different markers of neutrophils in oral health and disease in recent years in order to define potential cell subsets and their s...

CONCLUSIONS: Within the limitations of the current evidence, OH may be reinforced in patients with periodontal diseases by psychological interventions based on cognitive constructs and MI principles provided by oral health professionals. However, no conclusion can be drawn on their specific clinical efficacy as measured by reduction of plaque and bleeding scores over time. PMID: 31912530 [PubMed - as supplied by publisher]

ConclusionsIn HNC patients, oral status and taste change occurs throughout the cancer trajectory and represent potential concerns in cancer survivorship. Taste change (as evaluated by taste testing) occurred in all HNC patients, whereas olfactory changes occurred in 30% of cases. Management of oral changes and symptoms should be considered in all HNC patients in addition to dietary and nutritional guidance in patient care to promote oral intake. Continuing study of taste changes may further define this problem and support dietary and nutritional guidance and product development.
