Periodontal disease (Newman 2014) is a complex, multifactorial inflammatory/infectious process, which affects the gingiva (gums) and alveolar bone that support the teeth. The patient’s immune and inflammatory response to microbes, particularly subgingival microbes, is a key to the severity and progression of periodontal disease, and periodontal disease has been shown to have associations with the overall health of the patient. Inflammatory periodontal disease begins in the gingival tissues and spreads progressively into the tooth-supporting periodontal ligament and alveolar bone where it becomes the destructive form of periodontal disease, called periodontitis. This can ultimately lead to irreversible bone loss and subsequent tooth loss. Moderate periodontal diseases affect a majority of adults greater than 50 years or age, and severe periodontitis effects 5%–15% of adults (NIH 2017). Factors known to increase susceptibility to and severity of periodontal disease include smoking, diabetes mellitus, some anti-seizure medications, anti-cancer drugs, oral contraceptives, and some calcium channel blockers (NIH 2017).

Periodontitis is inflammation of the gums and gingival pocket areas by bacterial infection and is a major cause of tooth loss in adults. Once those tissues are damaged, the tissues are unable to be restored to their original form. Additionally, recent investigates show that periodontitis is also associated with several systemic disorders.114,115–116 In the authors’ laboratory, cell sheet therapy for curing periodontitis has been developed, and cell sheets, which are prepared from periodontal ligament (PDL) tissues, have been applied to various PDL-defective animal models.116,117,118,119,120,121–122 The safety and efficacy of PDL cell sheet therapy have been confirmed by animal experiments, and preclinical studies and a clinical study with autologous PDL cell sheets for periodontal tissue regeneration have also started since 2012.123

The oral health of a population can inform on diet, extra-masticatory use of teeth (e.g. pipe smoking), and general health (Hillson 2008). Poor oral health (particularly gum disease) can have severe systemic health consequences (Beck et al. 2000). The oral health of the adults from SJM is relatively typical of the time period, and fits well with the description of British populations by Roberts and Cox (2003, p. 324):‘At the outbreak of the First World War many of the working classes still had appalling dental health reflecting a soft cariogenic diet, a lack of oral hygiene and inadequate dental treatment’.
Dental Image Segmentation and Classification Using Inception Resnetv2
Published in IETE Journal of Research, 2021
Figure 7 shows the Pericoronal of a type of dental disease. Pericoronal is a localized penetration infection into the tissues surrounding the crown of a partially burst teeth. It occurs due to the accumulation of bacteria around the gum tissues that overlaps an impacted tooth.
