Combination Syndrome is a condition affecting edentulous patients, significantly impacting their lifestyle. It is now understood that the full spectrum of characteristics initially described by Kelly is not always essential for the identification of syndrome.
Our main objective was to determine the prevalence of Combination Syndrome among patients who attended the dental clinics of a Dentistry School of an Ecuadorian university between 2017 and 2019. We also aimed to investigate its association with potential factors such as type of edentulism, age, and sex.
This observational, and retrospective study analyzed 651 panoramic radiographs; 404 belonged to women and 247 to men. Radiographic signs of the syndrome, including premaxilla bone resorption, maxillary tuberosity enlargement, and posterior mandibular bone resorption, were evaluated. The study sought to ascertain the prevalence of syndrome, providing statistical data to highlight the importance of care for these patients.
Our findings indicate that 8.35% of all patients seen during the study period presented with the syndrome. Among these, a relationship with mandibular Class I edentulism was demonstrated. According to the Tolstunov Classification, Class I modification I was found to be associated with age but not with sex. Regarding age, older adults constitute a high-risk group.
We concluded that Combination Syndrome is strongly associated with mandibular Class I edentulism. Age is a key contributing factor, with a notably high prevalence observed in older adult patients.
