Particularly critical were 23 contiguous local administrative units in the northwest of the country, which formed a zone of elevated risk.<\/p>\n<h2>Clinical manifestations and prognosis<\/h2>\n<p>\u00abBefore meeting with patients during a surgical expedition, I perceived noma as a historical disease associated with poverty and malnutrition,\u00bb Dr. Adeoye said. \u00abI was shocked by how a condition that begins with gum inflammation can rapidly destroy significant portions of the face, and in the absence of treatment, lead to fatal outcome in 80\u201390% of cases\u00bb. <strong>The resulting color maps show the distribution of estimated risk across age groups, sex, and time periods,<\/strong> which enables health authorities and NGOs to strategically plan public awareness programs, prevention, and early disease detection.<\/p>\n<h2>Significance for dental practice<\/h2>\n<p>For dentists and other oral health specialists, the significance of this work is particularly great: since noma initially manifests in the oral cavity, <strong>dentists and dental therapists are in an ideal position to recognize early signs and urgently refer patients to specialists.<\/strong> The maps indicate where outreach programs, screening, and training of primary health care workers should be concentrated.<\/p>\n<h2>Practical implementation of results<\/h2>\n<p>Practical application of the results has already begun: the research group, in collaboration with the ZeroNoma initiative in northwestern Nigeria, is training volunteers and using the identified hotspots for targeted screening. <strong>Work published in the July issue of *Lancet Global Health* for 2026<\/strong> continues a series of studies by the team that began in 2019, when noma incidence in central Nigeria was first assessed.<\/p>\n<h2>Source<\/h2>\n<p><a href=\"https:\/\/www.dental-tribune.com\/news\/study-maps-noma-risk-hotspots-in-northern-nigeria\/\">Original publication<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A study using spatial modeling identified areas of greatest risk for developing one of the most severe infectious diseases of the oral cavity.
