Should systemic antibiotics be prescribed in periodontal abscesses and pericoronitis? A systematic review of the literature

This study assessed whether systemic antibiotics are beneficial or harmful in patients who present with an acute periodontal abscess or pericoronitis, with or without systemic involvement, and, if antibiotics are beneficial, which type, dosage, and duration are the most effective. Medline, Embase, and the Cochrane Library were screened from 1948 up to 1 April 2022 for systematic reviews, randomised clinical trials (RCTs), and other studies. Dedicated websites were consulted for systematic reviews, clinical practice guidelines, and health technology assessments on the topic. Outcomes of interest comprised tooth survival, swelling, pain, tooth mobility, periodontal probing depth, suppuration, adverse effects, quality of life measurements, and medication required for pain relief. Overall, five guidelines, seven systematic reviews, 15 RCTs, and 34 other studies were identified and selected for full-text assessment, but none of them fulfilled the inclusion criteria. At present there is no single randomised or non-randomised controlled trial assessing the harms and clinical effectiveness of systemic antibiotics in adults with a periodontal abscess or pericoronitis.

Surgical Site Infections Following Bimaxillary Orthognathic, Osseous Genioplasty, and Intranasal Surgery: A Retrospective Cohort Study

PURPOSE

Frequency estimates of surgical site infection (SSI) after orthognathic surgery vary considerably. The purpose of this study was to determine the incidence and site of SSIs and associated risk factors after bimaxillary orthognathic, osseous genioplasty, and intranasal surgery.

MATERIALS AND METHODS

The authors executed a retrospective cohort study of patients with a bimaxillary developmental dentofacial deformity (DFD) and symptomatic chronic obstructive nasal breathing. All patients underwent at a minimum Le Fort I osteotomy, bilateral sagittal ramus osteotomies (SROs), septoplasty, inferior turbinate reduction, and osseous genioplasty. The primary outcome variable studied was the incidence and site of SSI. Predictor variables were type and extent of prophylactic antibiotic used, demographic (age and gender), and anatomic (pattern of DFD, surgical site, and presence of third molar).

RESULTS

Two hundred sixty-two patients met the inclusion criteria. Their average age at surgery was 25 years (range, 13 to 63 yr) and there were 134 female patients (51%). The major presenting patterns of DFD included long face (30%) and maxillary deficiency (25%). Forty percent of patients undergoing an SRO and 47% of those undergoing a Le Fort I osteotomy underwent simultaneous removal of a third molar. Ninety percent of patients received cefazolin or cephalexin antibiotics. Overall, 5 of 1,048 (0.5%) osteotomy sites sustained an infection, including 1 chin and 4 ramus SSIs. There were no delays in bone healing. Fixation hardware removal was not required in any patient who developed an infection. Two of the 25 patients (8%) given clindamycin prophylaxis developed an SSI, whereas 3 of 237 patients (1%) receiving cefazolin did. Three of the 4 patients who developed an SRO SSI underwent simultaneous removal of an erupted or partially erupted mandibular third molar (P < .05).

CONCLUSIONS

In this study, the incidence of SSI was limited to 1% of patients who were given cefazolin or cephalexin extended for 5 days. The removal of an erupted or partially erupted mandibular third molar in conjunction with an SRO was associated with risk of SSI, but the incidence remains low.

Clindamycin in dentistry: More than just effective prophylaxis for endocarditis?

Clindamycin is a broad-spectrum antibiotic with activity against aerobic, anaerobic, and beta-lactamase-producing pathogens. This antibiotic has been used for many years as prophylactic treatment during dental procedures to prevent endocarditis. However, the spectrum and susceptibility of the bacteria species involved in dental infections indicate that clindamycin would also be an effective treatment option for these conditions. In addition to its antiinfective properties, clindamycin has high oral absorption, significant tissue penetration, including penetration into bone, and stimulatory effects on the host immune system. This review discusses the microbiologic and clinical evidence supporting the efficacy and safety of clindamycin for the successful management of dental infections.
