Genetic Polymorphisms in Serotonin Transporter (5HTT) and Catechol-O-Methyltransferase (COMT) On Dental Implant Loss–Pilot Project

In Brazil, the National Oral Health Survey re-vealed that tooth loss is still a very prevalent problem (1). Obviously, the negative impact on the quality of life of people with missing teeth is very great, triggering problems that affect their social behavior, so the substitution of lost dental elements by dental implants is considered a suita-ble way to return both aesthetics and physiology to these individuals. Despite the success of den-tal rehabilitation with dental implants, there are still cases of failure (2). Several factors may be associated with the dental implant loss, among them are the environmental factors and individu-al characteristics of each person, in this case, ge-netic factors gain importance.
