Dental inflammatory events including root canal treatments linked to rare Eagle Syndrome: Study
Dental inflammatory events including root canal treatments are linked to rare Eagle Syndrome, according to a new study. Eagle syndrome is caused by a calcified stylohyoid ligament (SHL).
The study has been published in the International Dental Journal.
Dystrophic calcification represents a situation in which insoluble mineral salts are deposited in soft tissues, in the absence of an increase in serum calcium and phosphate. This type of calcification has been incidentally detected in the head and neck region in more than 33% of the population.
This researchers conducted the study to investigate the relationship between calcification of the stylohyoid ligaments (SHLs) and odontogenic inflammatory events.
Cone-beam computed tomography scans of 175 patients were retrospectively assessed for the presence of SHL calcifications. Frequencies of 4 types of odontogenic inflammatory events were assessed using the same scans, namely dental extractions, root canal treatments, furcation lesions, and periapical lesions. Patients were telephone-interviewed and asked about histories of tonsillectomy and head and neck trauma. Mann–Whitney U and binary logistic regression tests were used to assess associations between SHL calcification and mean ranks of odontogenic inflammatory events.
