Evaluation of the Effect of Preoperative Amoxicillin on Bacteremia Associated with Exodontia in Periodontal and Periapical Pathology

AIM

The aim of this study was to evaluate the efficacy of preoperative prophylactic antibiotics of 2 g of oral amoxicillin on bacteremia following extraction of teeth with periodontal and periapical pathology.

MATERIALS AND METHODS

This study was carried out on 160 patients. The patients were divided into four groups of forty patients each: two antibiotic groups, with periodontal and periapical pathology, receiving 2 g of oral amoxicillin preoperatively and two control groups, with periodontal and periapical pathology, receiving no amoxicillin preoperatively. Blood samples were collected before the start of the procedure, intraoperatively, and immediately following extraction of teeth. The collected blood samples were cultured and studied for bacterial growth.

RESULTS

In the control group patients with periodontal pathology, 17 out of 40 blood samples showed growth of Streptococcus viridans along with Staphylococcus epidermidis. In the control group patients with periapical pathology, 14 out of 40 blood samples showed growth of S. viridans and Staphylococcus aureus. No growth was observed in both the groups on prophylactic antibiotics with 2 g of oral amoxicillin.

CONCLUSION

Bacteremia was found in 40% of the control group patients, while there was no bacteremia present in patients with preoperative administration of 2 g of oral amoxicillin.

Treatment of calcifying epithelial odontogenic tumor/Pindborg tumor by a conservative surgical method

Calcifying epithelial odontogenic tumor (CEOT) also known as Pindborg tumor is a rare odontogenic epithelial neoplasm. So far nearly 200 cases have been reported in literature. We are reporting a case of CEOT in a 42-year-old male patient with painless bony swelling in the mandible. Approximately, 50% of the cases are associated with an unerupted tooth or odontome, but was not so with our case. Considering the intrabony mandibular location of the lesion and its limited size, we opted for a more conservative surgery. The clinical, radiographic and histopathologic features and the surgical treatment done are discussed with relevant references.
