Periodontitis (PD) is a chronic gum illness that may be hard to cure for a number of reasons, including the fact that no one knows what causes it, the side effects of anti-microbial treatment, and how various kinds of bacteria interact with one another. As a result, novel therapeutic approaches for PD treatment must be developed. Additionally, supplementary antibacterial regimens, including local and systemic medication administration of chemical agents, are necessary for deep pockets to assist with mechanical debridement of tooth surfaces.

Introduction: Recent evidence suggests the relationship between periodontitis and systemic inflammation, which complete blood count can assess (CBC)-derived biomarkers such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). We conducted this meta-analysis to evaluate the levels of NLR and PLR of patients with periodontitis compared to those of healthy controls.  METHODS: Web of Science, PubMed, ProQuest, Scopus, and Open Grey were searched for studies published before October 20, 2024, without any limitation on date and language; then, using the random-effects model, we reported a standardized mean difference (SMD) with a 95% confidence interval (CI).

  • Scientists are using artificial intelligence (AI) to help dentists find fractures in the jaw by looking at special X-ray images.
  • A study looked at many research papers and found that AI can be pretty good at spotting these fractures, but only five studies were reliable enough to include in this review.
  • The results show that while AI can be useful, there needs to be more research with bigger and different sets of X-ray images to make sure it works well in real dental offices.
