Associations between the number of teeth lost in the interval between the pre\u2010 and post\u2010pandemic PMT visits and patient characteristics were tested using a negative binomial model.

Usually, the more compliant these patients are, the better results they can achieve. However, during the pandemic, many patients could not come to get their teeth and gums cleaned as regularly as they could before the pandemic. The present study looked at whether the health of the teeth and gums of patients was affected by the amount of time that passed until a patient came for a dental visit after the pandemic at the University of Colorado. The study results showed that some criteria used to examine tooth and gum health were affected, but others were not. The authors concluded that overall, the length of the interruption to receive dental care after the COVID\u201019 pandemic caused damage to tooth and gum health. The study results stress the importance of regular dental visits.<\/jats:p>\n
