Aim: This research aimed to examine the post-COVID-19 effects on dental health among JICS survey participants, exploring oral health changes during and following the pandemic. Materials and Methods: This study utilized random sampling through the JICS survey, involving 201 participants (aged 17–89). The control group (n=65, 32.7%) consisted of individuals without COVID-19 from 2019–2021, while the study group (n=134, 67.3%) included those who contracted the virus during this period. Symptom manifestation, intensity, and localization were assessed up to 9–12 months post-infection (2021–2022) across groups and genders, employing artificial intelligence (AI) and machine learning (ML) techniques, including descriptive analytics for pattern identification and predictive analytics for trend forecasting. Results: Analysis of dental symptoms potentially linked to COVID-19 identified 16 conditions, including hyperesthesia, grinding teeth, gum bleeding, gum pain, and pain in upper/lower teeth. Among 201 participants (aged 18–89, mean 28.6 years), symptoms lasted an average of 9.6 – max 18 months. Of those surveyed, 134 had contracted COVID-19 at various times prior to the survey. Among them, 90 individuals (67,3% of the total number of infected respondents) reported oral pain, a 44.3% increase over the standard hyperesthesia prevalence. This group consisted of 36 men and 54 women. These 7 people (those with intense pain) constituted 7,8% Within this subgroup, 2 men and 5 women complained of intense pain, representing 2,2% and 5,6% of those with oral pain, respectively. Older age groups showed more severe symptoms, like gum pain (mean 86 years), while women reported greater severity than men. Conclusions: The study shows dental symptoms potentially linked to COVID-19 vary by severity and age, with older individuals experiencing severe issues like gum pain. The oral health monitoring could identify symptoms and enhance treatments, especially for older adults. Further research is needed to confir long-term impacts and refine treatment
