In severe and untreated cases, bacterial infection combined with the host's immune response can cause bone resorption, or the breakdown of bone tissue in the tooth root. Moreover, traditional treatments for advanced dental caries, such as surgery, can result in bone defects that require complex bone grafting procedures. https://medicalxpress.com/news/2025-05-overexpressing-mirna-27a-human-dental.html Thu, 08 May 2025 16:06:48 EDT news665939196 The economic impact of dental caries (tooth decay) is disproportionately higher in the most deprived groups, with estimated per-person costs of approximately £18,000 in the UK that could be dramatically reduced with targeted preventative measures, found new research. https://medicalxpress.com/news/2024-12-reveals-economic-burden-tooth-decay.html Fri, 20 Dec 2024 11:49:04 EST news653917741 IgA nephropathy (IgAN) is an immune response disease affecting the filtering units of the kidneys.
