Pericoronitis is an inflammatory disease that occurs after the eruption of the lower wisdom teeth and affects the surrounding tissues, with a complex microbial and traumatic etiology, manifested by an erythematous swelling and gum hyperemia in the retromolar area. The main goal was to determine the etiological spectrum of the microorganisms involved in acute pericoronitis and to evaluate the antibiotics, antiinflammatory drugs effect on pericoronitis treatment. The study included 30 patients (18 male, 12 female), aged between 18-45 years (27,8±8,2 years) with acute pericoronitis of the lower wisdom tooth. The study determined the severity of infection related to subjective and objective clinical symptoms (pain, swelling, congestion), the incidence of various streptococci; antibiotics resistance analysis was performed for in order to determine the sensibility and the rate between monomicrobial and polymicrobial cultures. 14 references, 4 figures.
Background. Coronectomy of the wisdom teeth is an alternative surgical procedure to tooth extraction, which aims to preserve the roots of the wisdom teeth in the dental socket after surgical separation of the crown, in order to avoid the injury of the inferior alveolar vascular-nervous bundle. Purpose. Minimizing the damage to the inferior alveolar nerve when extracting lower third molars caused by the intimate relationship between the nerve and the roots of the teeth, by using the technique of coronectomy, or intentional root retention. Material and Methods. Patients who reported to University Dental clinic during the period 2020–2021 for surgical removal of impacted L3M were screened for nerve–root relationship with OPG or CBCT. 15 patients underwent coronectomy as a procedure to remove the crown and upper third of the roots of a lower third molar to reduce the risk of damage to the inferior alveolar nerve. Results. 15 patients were enrolled in this study, with a total of 17 lower third molars. Sixteen sites healed primarily, but in 1 case the sockets on both sides opened and failed to close secondarily. In this case, the root fragments were later removed and found to be mobile. Conclusion. Coronectomies are safer to perform than complete extractions in situations in which the third molar is in close proximity to the mandibular canal. The technique appears to be associated with a low incidence of complications and the removal of remaining roots is required in around 6-7% of cases due to the mesial migration of the fragment and not any symptoms or reinfection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
