Abstract
Antibiotics are commonly prescribed as a preventive measure, particularly post-tooth extraction, aiming to minimize the risk of infection. Preemptive analgesia functions by disrupting the nervous system's ability to encode pain stimuli, thus preventing the formation of pain memory. Dentists often recommend analgesics and antibiotics either as adjuncts or sole treatments for various dental conditions, offering both efficacy and cost-effectiveness. A comprehensive literature search was conducted across multiple databases, including PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Science Direct, and Lilac, using MeSH terms relevant to the role of antibiotics and analgesics in systemically ill patients undergoing tooth extraction. Out of 178 articles screened, 83 underwent full-text assessment for eligibility, and six were selected for qualitative analysis. The review process adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, ensuring methodological rigor and transparent reporting. Across diverse study populations, the role of antibiotics and analgesics consistently demonstrated a statistically significant impact. Hence, the utilization of analgesics and antibiotics plays a pivotal role in preventing infection following tooth extraction in systemically ill patients, thereby promoting optimal oral hygiene and overall health.

Prophylactic Use of Pentoxifylline and Tocopherol for Prevention of Osteoradionecrosis of the Jaw after Dental Extraction in Post-Radiated Oral and Oropharyngeal Cancer Patients: An Initial Case Series. Dent J (Basel) 2024; 12:83. [PMID: 38667995 PMCID: PMC11049290 DOI: 10.3390/dj12040083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Revised: 03/13/2024] [Accepted: 03/21/2024] [Indexed: 04/28/2024] Open
Abstract
Osteoradionecrosis of the jaw is a morbid complication of radiotherapy in patients with oral and oropharyngeal cancers that may be precipitated by dental extractions. Pentoxifylline and tocopherol (PENTO) has been utilized in the management of osteoradionecrosis and as prophylaxis for post-radiated head and neck oncology patients requiring an invasive dental procedure. This observational study aims to report the outcome of the prophylactic use of PENTO in the prevention of osteoradionecrosis of the jaw after dental extractions in post-radiated oral and oropharyngeal cancer patients and to review the current literature on this topic. Four post-radiated oral and oropharyngeal oncology patients were referred to the dental oncology clinic of the University Dental Practice, University of Tennessee Health Sciences Center for dental extractions. All four patients were prescribed pentoxifylline 400 mg BID (twice a day) and tocopherol 400 IU BID (oral tablets) for 2 weeks before extraction(s) and for 6 weeks after extraction(s). All patients were followed up every week after the second week post-extraction if feasible until the extraction site(s) healed (covered by mucosa). The assessment endpoint was defined as 6 weeks post-extraction with the outcomes assessed as using four categories determined by the area of exposed bone: complete healing (complete mucosal coverage of extraction site); partial healing (reduction in size of extraction site); no change; and progression (increase in size of the extraction site). At the assessment endpoint, all patients had complete healing of all extraction sites. The ORN rate at the patient level (0/4) and individual tooth level (0/8) was 0%. All patients tolerated the PENTO medications and no adverse effects from the use of these medications were reported. This limited study in addition to the other reviewed studies estimates the rate of ORN at the patient level as 3.2% (14/436) for post-radiated head and neck oncology patients after dental extractions/invasive oral procedures. In conclusion, this PENTO regimen can reduce/prevent the incidence of ORN in post-radiated head and neck oncology patients. This safe and cost-effective protocol (PENTO regimen) should be further evaluated as prophylaxis for post-radiated head and neck oncology patients requiring an invasive dental procedure. We recommend large prospective studies to be carried out to further validate these findings.

Abstract
BACKGROUND Jaw osteoradionecrosis (ORN) is a complication in patients with previous head and neck radiotherapy. Its incidence increases with dental extractions. Hence, this review aimed to evaluate the efficacy of adjunctive treatment modalities undertaken at the time of extraction in previous head and neck radiotherapy patients in preventing ORN. METHODS A systematic review was conducted, where studies with data on ORN incidence after extraction with or without adjunctive interventions were included. Meta-analyses were conducted to estimate the pooled prevalence of ORN per intervention and the pooled odds ratio for incidence of ORN between interventions. RESULTS In total, 1520 patients in 29 studies were included. Interventions identified were hyperbaric oxygen (HBO), pentoxifylline-tocopherol (PENTO), antibiotics (ABX), platelet-rich fibrin and photobiomodulation. The pooled prevalence of ORN for HBO (4.6%), PENTO (3.4%) and ABX (3.8%) was significantly lower than the Control (17.6%). For studies with direct comparisons between groups, HBO had lower but not significant odds of developing ORN than the Control (OR 0.27) and ABX (OR 0.57). CONCLUSIONS HBO, PENTO and ABX may reduce the incidence of ORN compared to no intervention. Given that all three have similar incidences of ORN, ABX may be the most cost-effective and accessible adjunctive modality.

Abstract
AIMS Radiation caries (RC) is a highly prevalent and chronic complication of head and neck radiotherapy (HNRT) and presents a challenge for clinicians and patients. The present study aimed to assess the impact of RC on the morbidity and mortality outcomes of head and neck squamous cell carcinoma (HNSCC) patients. METHODS AND RESULTS Patients were divided into three groups: (1) RC (n = 20), (2) control (n = 20), and (3) edentulous (n = 20). Information regarding the number of appointments, dental procedures, osteoradionecrosis (ORN), prescriptions, and hospital admissions were collected. Mortality outcomes were assessed through disease-free survival (DFS) and overall survival (OS) rates. RC patients required more dental appointments (p < .001), restorations (p < .001), extractions (p = .001), and antibiotic and analgesic prescriptions (p < .001). Kaplan-Meier subgroup analyses showed a significantly increased risk of ORN in RC compared to edentulous patients (p = .015). RC patients presented lower DFS rates (43.2 months) than the control and edentulous groups (55.4 and 56.1 months, respectively). CONCLUSIONS RC impacts morbidity outcomes among cancer survivors due to increased demand for medication prescriptions, multiple specialized dental appointments, invasive surgical treatments, increased risk of ORN, and increased need for hospital admissions.

Antibiotic therapy for the prevention of osteoradionecrosis following tooth extraction in head-and-neck cancer patients postradiotherapy: An 11-year retrospective study. Natl J Maxillofac Surg 2021; 12:333-338.

Abstract
Introduction: One of the most important complications of radiotherapy (RT) for head-and-neck cancer (HNC) is osteoradionecrosis (ORN) of the jaws, which mostly arises from tooth extractions. The ORN treatment still represents a great challenge; therefore, the prevention is of paramount importance. Thus, the present study aimed to evaluate retrospectively a perioperative systemic antibiotic therapy protocol for the prevention of ORN following tooth extraction in head-and-neck patients post-3D conformal RT. Materials and Methods: A retrospective medical record review was performed considering HNC patients submitted to RT in the period between 2008 and 2019. They necessarily received oral antibiotic therapy with Clindamycin 300 mg every 8 h for 10 days, with the first dose 3 days before the tooth extraction. Results: Forty-nine patients met the study criteria, with a total of 107 teeth extracted. Regarding the 47 patients who did not develop ORN, 103 tooth extractions were identified (96.3%). Only two patients developed ORN at two adjacent teeth sites (3.7%). Conclusion: The proposed perioperative systemic antibiotic therapy protocol seems to be efficient to prevent ORN following tooth extraction in postirradiated HNC patients.

Abstract
Osteoradionecrosis is a relatively rare but potentially morbid and costly complication of radiation therapy for head and neck cancer. Multidisciplinary diagnosis and treatment are essential. Despite evidence guiding individual aspects of care for osteoradionecrosis, there is a lack of broad consensus on the overall diagnosis and management of this condition. This study comprehensively reviews the literature, with a focus on the past 10 years, to guide evaluation and treatment.

Abstract
For decades, hyperbaric oxygen (HBO) has often been part of the treatment of osteoradionecrosis (ORN), despite controversy in the literature about its efficacy. An online survey was conducted to investigate the use of HBO in the treatment of ORN by Dutch oral and maxillofacial surgeons and to assess their perception of its efficacy. Of the 53 Dutch oral and maxillofacial surgery units contacted, 49 (92%) replied. Thirty-five were not head and neck cancer (HNC) units or preferred partner (PP-HNC) units recognized by the Dutch Head and Neck Association. All HNC and PP-HNC units (group 1) treated ORN patients, compared to only 12 (34%) of the non-HNC units (group 2). The average number of ORN patients seen and treated was higher in group 1. The units in group 1 more often referred patients for HBO therapy (HBOT) than those in group 2 (93% vs 84%). The efficacy of HBOT in curing ORN, rated on a scale of 1 to 5 points, was 3.7 in group 1 and 3.2 in group 2. This survey shows a trend towards centralization of ORN care to more experienced units. These units tend to use HBOT in curing ORN.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy of photobiomodulation therapy (PBMT) on the mucosal healing of patients submitted to simple dental extractions after head and neck radiation therapy (HNRT). METHODS Forty surgical procedures were randomly assigned into two groups: G1: dental extraction + PBMT (n = 19) and G2: dental extraction + sham-PBMT (n = 21). All patients received antibiotic therapy and the surgical alveolotomy to promote primary closure of the surgical site. Group 1 was submitted to PMBT according to the following parameters: 808 nm, 40 mW, 100 J/cm2, 70 s, 2.8 J/point, 14 J/session, and area of 0.028cm2. The primary outcome was complete mucosal lining at 14 days, and the secondary outcomes were the presence of infection, postoperative pain, and analgesics intake at 7 days. The patients were evaluated every 7 days until 28 days. RESULTS Alveolar mucosal lining was faster in G1, and at 14 postoperative days, 94.7% patients evolved with complete alveolar mucosal lining compared to no patient from G2 (p < 0.001). Patients from G1 reported postoperative pain less frequently (G1 = 4, 21.1% × G2 = 14, 66.7%, p = 0.005), and also reported lower intake of analgesic pills at D7 (21.1% × 66.7%, p = 0.005%). PBMT had a significant positive impact on both postoperative pain (NNT = 2.192, CI95% = 1.372-5.445) and mucosal healing (NNT = 1.056, CI95% = 0.954-1.181). CONCLUSIONS This preliminary study strongly supports the use of PMBT to promote surgical alveolar mucosal lining in a shorter time and with less postoperative pain.

Abstract
BACKGROUND Osteoradionecrosis of the mandible is the most common serious complication of radiotherapy for head and neck malignancy. For decades, hyperbaric oxygen has been employed in efforts to prevent those cases of osteoradionecrosis that are precipitated by dental extractions or implant placement. The evidence for using hyperbaric oxygen remains poor and current clinical practice varies greatly. We describe a protocol for a clinical trial to assess the benefit of hyperbaric oxygen in the prevention of osteoradionecrosis during surgery on the irradiated mandible. METHODS/DESIGN The HOPON trial is a phase III, randomised controlled, multi-centre trial. It employs an unblinded trial design, but the assessment of the primary endpoint, i.e. the diagnosis of osteoradionecrosis, is assessed on anonymised clinical photographs and radiographs by a blinded expert panel. Eligibility is through the need for a high-risk dental procedure in the mandible where at least 50-Gy radiotherapy has been received. Patients are randomised 1:1 to hyperbaric oxygen arm (Marx protocol) : control arm, but both groups receive antibiotics and chlorhexidine mouthwash. The primary endpoint is the presence of osteoradionecrosis at 6 months following surgery, but secondary endpoints include other time points, acute symptoms and pain, quality of life, and where implants are placed, their successful retention. DISCUSSION The protocol presented has evolved through feasibility stages and through analysis of interim data. The classification of osteoradionecrosis has undergone technical refinement to ensure that robust definitions are employed. The HOPON trial is the only multi-centre RCT conducted in this clinical setting despite decades of use of hyperbaric oxygen for the prevention of osteoradionecrosis.

Abstract
BACKGROUND Patients experience considerable dental-related difficulties following head and neck cancer (HNC) treatment including problems with chewing, dry mouth, oral hygiene, appearance and self-esteem. These can go unrecognised in busy follow-up clinics. The Patient Concerns Inventory (PCI) is specifically for HNC patients, enabling them to select topics they wish to discuss and members of the multi-professional team they want to see. AIM The study aimed to identify the clinical characteristics of patients raising dental concerns on the PCI and to explore the outcome of onward referral. Assessments included the PCI and the University of Washington Quality of Life Questionnaire (UW-QOL) version 4, with clinic details collated from hospital and cancer databases. METHOD PCI data were obtained from 317 HNC patients between 2007 and 2011. Their mean age was 63 years and 60% were male. Most had oral squamous cell carcinoma and underwent surgery. The median (IQR) time from treatment to first PCI was 13 (4-42) months. RESULTS Three comparison groups were identified: patients with significant chewing problems, patients without significant chewing problems who wanted to discuss dental-related concerns and patients without significant chewing problems who did not want to discuss such concerns. Fifty-two percent reported either a significant chewing problem on the UW-QOL or a wish to discuss dental-related concerns. A quarter specifically asked to talk to a dental professional. Clinical characteristics significantly associated with dental issues were stage, primary treatment and free flap reconstruction. Clinic letters were copied to only 10% of general dental practitioners (GDPs). CONCLUSION Better communication with GDPs is essential.

Abstract
Patients undergoing radiation therapy as either primary, adjuvant, combination therapy or palliative management of head and neck malignancies are prone to a range of dental complications. Strategies for prevention and management of such complications may be controversial. This article aims to highlight the current understanding and management of the dental needs for patients before, during and after radiation therapy.

Abstract
Management of irradiated patients with cancer in the head and neck region represents a challenge for multidisciplinary teams. Radiotherapy promotes cellular and vascular decrease that results in a low response rate in the healing. Consequently, surgical procedures in irradiated tissues present high rates of complication. Osteoradionecrosis (ORN) is the most severe sequelae caused by radiotherapy. It is associated with previous extractions especially those carried out post-irradiation. The management of this side effect is difficult and can result in bone or soft tissue loss, affecting the quality of life. The literature regarding dental extractions performed before and after head and neck radiotherapy was evaluated, focusing on indications, criteria, surgical techniques and adjunctive therapies such as antibiotics and hyperbaric oxygen. Osteoradionecrosis can be minimized by oral evaluation and care prior to irradiation and healing time which allows tissue repair until the commencement of radiotherapy. In dental extractions realized after irradiation, minimal trauma, alveolectomy, primary alveolar closure and adjunctive therapies are recommended. Patients must be evaluated before radiation therapy and at that time all unrestorable teeth and/or teeth with periodontal problems must be extracted to reduce the post-radiotherapy exodontias that contribute to ORN. Once dental extractions become unavoidable after irradiation, additional care is needed.

Abstract
Chemotherapeutic management of the microbial milieu that impacts patients undergoing surgery is profoundly important in surgery involving the head and neck region. This region is a repository for a diverse population of microbes, which stand ready to invade the underlying structures once the barriers have been breached. This article evaluates human resistance to these microorganisms and reviews conditions that may increase susceptibility in patients undergoing surgery.

Abstract
PURPOSE To critically analyze controversial osteoradionecrosis (ORN) prevention techniques, including preradiation extractions of healthy or restorable teeth and the use of prophylactic antibiotics or hyperbaric oxygen (HBO) treatments for preradiation and postradiation extractions. METHODS The author reviewed ORN studies found on PubMed and in other article references, including studies on overall ORN incidence and pre- and postradiation incidence, with and without prophylactic HBO or antibiotics. RESULTS Owing in part to more efficient radiation techniques, the incidence of ORN has been declining in radiation patients over the last 2 decades, but the prevention of ORN remains controversial. A review of the available literature does not support the preradiation extraction of restorable or healthy teeth. There is also insufficient evidence to support the use of prophylactic HBO treatments or prophylactic antibiotics before extractions or other oral surgical procedures in radiation patients. CONCLUSIONS To prevent ORN, irradiated dental patients should maintain a high level of oral health. A preradiation referral for a dental evaluation and close collaboration by a multidisciplinary team can be invaluable for radiation patients. As with most other dental patients, restorable and healthy teeth should be retained in irradiated patients. The use of prophylactic HBO or antibiotics should be reconsidered for preradiation and postradiation extractions.

Abstract
The issue of prophylactic antibiotic therapy in third molar surgery is highly controversial. The current evidence questions the benefits of routine prophylactic antibiotic therapy which does not appear to overcome the risk of undesirable outcomes after third molar removal. In our opinion there is no justification for routine antibiotic prophylaxis for third molar surgery.
