The necessity of administrating antibiotic prophylaxis to patients with diabetes mellitus prior to oral surgical procedures-a systematic review

Risk factors for oral infection and dry socket post-tooth extraction in medically complex patients in the absence of antibiotic prophylaxis: A case-control study

INTRODUCTION

Dry socket and infection are complications of tooth extractions. The objective was to determine risk factors for post-extraction complications in patients without antibiotic prophylaxis stratified by early- and late-complications and complication type (oral infection and dry socket).

METHODS

Retrospective, case (with complications)-control (without complications) study of patients (n = 708) who had ≥1 extraction performed at any Veterans Health Administration facility between 2015-2019 and were not prescribed an antibiotic 30 days pre-extraction.

RESULTS

Early complication cases (n = 109) were more likely to be female [odds ratio (OR) = 2.06; 95% confidence interval (CI):1.05-4.01], younger (OR = 0.29; 95% CI:0.09-0.94 patients ≥ 80 years old, reference:18-44 years), Native American/Alaska Native (OR = 21.11; 95% CI:2.33-191.41) and have fewer teeth extracted (OR = 0.53 3+ teeth extracted; 95% CI:0.31-0.88, reference:1 tooth extracted). Late complication cases (n = 67) were more likely to have a bipolar diagnosis (OR = 2.98; 95% CI:1.04-8.57), history of implant placement (OR = 8.27; 95% CI:1.63-41.82), and history of past smoking (OR = 2.23; 95% CI:1.28-3.88).

CONCLUSION

Predictors for post-extraction complications among patients who did not receive antibiotic prophylaxis were similar to prior work in cohorts who received prophylaxis. Unique factors identified in a medically complex population included being younger, Native American/Alaska Native, having mental health conditions, history of a dental implant, and fewer teeth extracted.

Hyaluronic Acid Treatment of Post-Extraction Tooth Socket Healing in Subjects with Diabetes Mellitus Type 2: A Randomized Split-Mouth Controlled Study

The present study aimed to investigate the effect of HA in improving post-extraction socket healing in subjects with diabetes mellitus (DM) type 2. DM patients requiring bilateral extraction of the homologous teeth were visited at the C.I.R. Dental School, University of Turin. After the extractions, one site was randomly assigned to the test (T) group (postoperative application of HA), while the other site was assigned to the control group (C, no treatment). Patients were then followed after 3, 7, 14, and 21 days. Primary outcomes were the healing index and socket closure. The Mann-Whitney test or the Student's t-test was used for nonparametric or parametric distributed variables. The chi-square test was used if the estimated data in any given cell were >5, otherwise the Fisher test was adopted. A p < 0.05 was considered statistically significant. In total, 36 patients (n = 36) were enrolled in this study for a total of 72 extractions (n = 72). Sockets treated with HA showed significantly (p < 0.05) better healing index values at day 7 (p = 0.01) and at day 14 (p = 0.02) and significantly (p < 0.05) better socket closure values at day 3 (p = 0.04), day 7 (p = 0.001) and day 14 (p = 0.001) compared to the C group. Based on the clinical results, HA seems to be promising in improving the timing and the quality of post-extractive wound healing in DM patients. Further clinical research, as well as histological investigations, are required to confirm the results.

Avoiding implant-related complications in medically compromised patients with or without unhealthy lifestyle/Elevated oxidative stress

Increased human life expectancy broadens the alternatives for missing teeth and played a role in the widespread use of dental implants and related augmentation procedures for the aging population. Though, many of these patients may have one or more diseases. These systemic conditions may directly lead to surgical complications, compromise implant/bone healing, or influence long-term peri-implant health and its response to biologic nuisances. Offering patients credible expectations regarding intra- and postoperative complications and therapeutic prognosis is an ethical and legal obligation. Clear identification of potential types of adverse effects, complications, or errors is important for decision-making processes as they may be related to different local, systemic, and technical aspects. Therefore, the present review structures the underlying biological mechanisms, clinical evidence, and clinical recommendations for the most common systemic risk factors for implant-related complications.

The outcome of prolonged postoperative antibiotics on wound healing in orthognathic surgery: A meta-analysis

We conducted a meta-analysis to assess the outcome of prolonged postoperative antibiotics (PA) on wound healing in orthognathic surgery (OS). A systematic literature search up to January 2023 was performed and 1021 related studies were evaluated. The chosen studies comprised 1057 OS subjects who participated in the selected studies' baseline, 446 of them used short-term PA, and 611 used long-term PA. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of prolonged PA on wound infection after OS by the dichotomous methods with a random or fixed effect model. The short-term PA resulted in significantly higher wound infection (OR, 4.27; 95% CI, 2.97-6.14, P < 0.001) with low heterogeneity (I²  = 27%) compared to the long-term PA in OS. The short-term PA resulted in significantly higher wound infection compared to the long-term PA in OS. Though care should be taken when dealing with the results since a large number of the selected studies had <100 subjects as a sample size.
