Survival rates for children treated for malignant diseases continue to improve, yet many survivors face persistent late oral complications that affect function, aesthetics, and quality of life. Oncological therapy, especially at a young age and following head and neck radiotherapy or intensive chemotherapy, can disrupt dental and craniofacial development, resulting in dental developmental disorders, enamel defects, salivary gland dysfunction, caries susceptibility, periodontal problems, trismus, and osteoradionecrosis of the jaw. Although these effects are partially known, they are frequently underrecognized in routine practice, and many children do not receive adequate long-term dental follow-up. A key challenge highlighted in the recent literature is the absence of structured, evidence-based guidelines for monitoring and managing late oral effects. The article emphasizes the need for clearer recommendations, better communication of oncological treatment histories, and stronger integration of dental professionals within survivorship care. Developing standardized follow-up protocols will be essential to ensure timely detection, consistent management, and improved oral health outcomes for childhood cancer survivors. This article is intended as a narrative review, synthesizing available evidence from key publications to highlight clinically relevant late oral complications and gaps in current survivorship care.

Background: The oncologic safety of dental implants (DIs) in patients with oral field cancerization (OFC) remains uncertain. Increasing reports of oral squamous cell carcinoma (OSCC) developing adjacent to DIs have raised concerns regarding the interaction between implants, chronic inflammation, and genetically altered mucosa. Methods: A comprehensive PubMed/MEDLINE search was performed through June 2025 to identify English- or Spanish-language publications reporting primary OSCC occurring in proximity to DIs. Extracted variables included patient demographics, tumor site, clinical presentation, presence of oral potentially malignant disorders (OPMD) or prior OSCC, peri-implant inflammation, management, and outcomes. Cases describing clinical features compatible with field-altered mucosa (e.g., OPMD or prior OSCC) were evaluated descriptively, recognizing that formal histopathologic or molecular evidence of OFC was rarely reported. Results: A total of 105 implant-associated OSCC cases were identified. The mean patient age was 66.8 years (range: 40–90), with a female predominance (1.3:1). The mandible was the most frequently involved site (86.7%). A prior history of OPMD or OSCC was reported in 53 patients (50.5%), and peri-implantitis preceding diagnosis in 21 cases (19.0%). The most common clinical presentations were exophytic (59.0%) and ulcerated (37.1%) lesions, frequently mimicking peri-implantitis and contributing to diagnostic delay. Reported outcomes included recurrence in 11 cases (10.5%) and death in 13 cases (12.4%). Conclusions: Current evidence suggests that implant-associated OSCC frequently occurs in patients with pre-existing mucosal alterations and may be influenced by the interaction of field cancerization with local inflammatory and mechanical factors. Implant rehabilitation in individuals with OPMD, prior OSCC, or epithelial dysplasia should be undertaken cautiously, with rigorous long-term surveillance to ensure oncologic safety. Full article

Tyrosine kinase inhibitors (TKIs), either as single agents or in combination with other drugs, have become a gold standard in many oncological pathologies. The identification, analysis, and clinical management of their multiple and various systemic adverse events are a clear requirement and represent a true challenge in daily practice. For this narrative review, registration clinical trials that have led to the approval of certain TKI protocols in the setting of renal cell carcinoma (RCC) were identified via the latest version of the National Comprehensive Cancer Network (NCCN) kidney cancer guidelines. The following keywords were used: Axitinib, Cabozantinib, Lenvatinib, Pazopanib, Sorafenib, Sunitinib, and Tivozanib. RCC therapies have been proven to frequently induce oral symptoms and pathologies such as stomatitis, dysgeusia, xerostomia, osteonecrosis of the jaws, oral dysesthesia, geographic tongue, and dental and periodontal damage. The aim of this review is to emphasize the mechanisms of these common drug-induced buccodental toxicities associated with TKI therapies in RCC and to draft a general clinical management of these adverse events, in order to improve patients’ quality of life and treatment adherence.

Oncological patients or the individuals scheduled for cardiovascular surgeries are at risk of both oral and systemic complications when existing dental pathologies are not addressed before these therapies. This narrative review explores the current literature on the role of pre-treatment dental care in reducing unfavorable outcomes and promoting treatment efficacy in medically compromised patients. The data show that early dental intervention, particularly prior to head and neck radiotherapy, considerably reduces the risk of osteoradionecrosis, rampant radiation caries, and xerostomia. Chemotherapy-associated mucositis, infections, and microbial imbalance are similarly worsened by untreated oral disease but may be managed through early sanitation and hygiene reinforcement. In cardiac patients, conditions such as apical periodontitis and periodontitis may lead to bacteremia, infective endocarditis, or prosthetic valve infections, highlighting the systemic relevance of oral health. Tooth extractions, restorative treatment of carious lesions, and control of active oral infections performed before systemic therapy can reduce complication rates, improve treatment continuity, and enhance patients’ quality of life. Integrating comprehensive dental assessment into routine pre-treatment planning allows early identification of oral health risks and supports a multidisciplinary approach that optimizes overall clinical outcomes.

This review systematically examines the oral complications associated with conventional and novel anti-cancer therapies. It highlights that while molecularly targeted agents including monoclonal antibodies targeting the vascular endothelial growth factor and its receptor, the epidermal growth factor receptor, tyrosine kinase inhibitors, and immune checkpoint inhibitors tend to exhibit a lower overall toxicity profile compared to traditional cytotoxic chemotherapeutics, they are nonetheless linked to significant oral adverse events. These complications encompass inflammatory mucosal reactions known as mucositis, salivary gland dysfunction leading to a sensation of dryness in the mouth, taste alterations referred to as dysgeusia, and, critically, medication-related osteonecrosis of the jaw. In particular, bone-modifying agents such as bisphosphonates and denosumab disrupt bone remodeling and the formation of new blood vessels, thereby increasing the susceptibility to osteonecrosis of the jaw, especially following invasive dental procedures. The review delineates the multifactorial pathogenesis underlying these toxicities, which involves direct cell toxicity, impaired wound healing, and secondary infections. Furthermore, it emphasizes the importance of pre-treatment dental evaluation and preventive strategies including patient education, prophylactic dental care, and the integration of adjunctive therapies such as laser therapy and autologous platelet concentrates to mitigate these adverse effects. The analysis advocates for interdisciplinary collaboration between oncologists and dental professionals to optimize management protocols, enhance treatment adherence, and ultimately improve the quality of life for oncology patients undergoing anti-cancer therapy.

This review aims to provide a comprehensive overview of the literature on the oral side effects caused by radiotherapy for head and neck cancers. Various treatments are examined to mitigate these sequelae, and a protocol is proposed for dentists and dental hygienists to manage oncological patients. A literature search was conducted to select relevant articles addressing the effects of radiotherapy treatments on the oral cavity, with a particular focus on the development of mucositis, candidiasis, changes in salivary pH, trismus, fibrosis, and alterations in the oral biofilm. PubMed and MedLine were used as search engines, with keyword combinations including: head and neck cancer, mucositis, candida, dental care, dental hygiene, epidemiology, oral microbiome, biofilm, trismus, fibrosis, and salivary pH. A total of 226 articles were identified, spanning the period from 1998 to 2023. Articles deemed inappropriate or in languages other than English or Italian were excluded. A management protocol for oncological patients was proposed, divided into two phases: home-based and professional. Despite the advancements in intensity-modulated radiation therapy, it is impossible to completely avoid damage to healthy tissues. Preventive education and counseling in the dental chair, ongoing motivation, and education about oral hygiene are crucial to combine a good therapeutic outcome with an improved quality of life for the patient.

Radiation therapy (RT) plays a crucial role in the treatment of head and neck cancers (HNCs). This paper emphasizes the importance of effective communication and collaboration between radiation oncologists and dental specialists in the HNC care pathway. It also provides an overview of the role of RT in HNC treatment and illustrates the interdisciplinary collaboration between these teams to optimize patient care, expedite treatment, and prevent post-treatment oral complications. The methods utilized include a thorough analysis of existing research articles, case reports, and clinical guidelines, with terms such as ‘dental management’, ‘oral oncology’, ‘head and neck cancer’, and ‘radiotherapy’ included for this review. The findings underscore the significance of the early involvement of dental specialists in the treatment planning phase to assess and prepare patients for RT, including strategies such as prophylactic tooth extraction to mitigate potential oral complications. Furthermore, post-treatment oral health follow-up and management by dental specialists are crucial in minimizing the incidence and severity of RT-induced oral sequelae. In conclusion, these proactive measures help minimize dental and oral complications before, during, and after treatment. Full article

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. Full article

Aims: Medication-related osteonecrosis of the jaw (MRONJ) is a drug-related adverse reaction characterized by bone destruction and necrosis in the jaw. This case series aims to evaluate the treatment approaches and outcomes in MRONJ patients. Materials and methods: The retrospective study was conducted at the Dental Unit of the University of Bari, Italy. Patients with MRONJ were treated and followed up for 60 months. The treatment approach involved piezosurgery and concentrated growth factor (CGF). Six clinical cases from this group are described in detail. Results: None of the patients showed recurrence of necrotic MRONJ lesions during the follow-up period. The surgical interventions, including bone resections and the application of CGF, resulted in successful mucosal healing and the prevention of disease progression. Conclusions: This study highlights the complexity of managing MRONJ and the importance of a multidisciplinary approach. Conservative treatment options and minimally invasive surgery have shown efficacy in controlling symptoms and improving patients’ quality of life. However, the optimal treatment approach remains a challenge, and further studies are needed to evaluate alternative therapies and resective surgery. A comprehensive preoperative evaluation and collaboration among dental, endocrinology, and oncology specialists are crucial for personalized and multidisciplinary management. Ongoing research efforts are necessary to explore new therapeutic modalities and improve our understanding of MRONJ management, providing better support to patients dealing with this complex condition.

Background: In the literature, among oral health prevention programs dedicated to cancer patients, a wide heterogeneity is evident. The purpose of this work is to analyze the available scientific evidence for the treatment of head and neck cancer (HNC) patients undergoing resective surgery and radiotherapy and to draw up a diversified oral hygiene protocol during oncological therapy. Methods: PubMed was used as database. Studies published from 2017 to September 2022 were analyzed. Studies investigating the effectiveness of the preventive procedures carried out by the dental professionals in HNC patients undergoing postoperative adjuvant therapy have been taken into account. Results: The application of the search string on PubMed allowed the selection of 7184 articles. The systematic selection of articles led to the inclusion of 26 articles in this review, including 22 RCTs, 3 observational studies, and 1 controlled clinical study. Articles were divided according to the debated topic: the management of radiation-induced mucositis, xerostomia, the efficacy of an oral infection prevention protocol, and the prevention of radiation-induced caries. Conclusions: Dental hygienists are fundamental figures in the management of patients undergoing oncological surgery of the maxillofacial district. They help the patient prevent and manage the sequelae of oncological therapy, obtaining a clear improvement in the quality of life. Full article

In 2021, our group published a laboratory study on the impact of PBM on human gingival fibroblasts. The in vitro results confirmed the fact that the appropriately selected wavelength and properly selected parameters of the laser settings can increase cell proliferation, modulate inflammatory markers, and decrease the susceptibility of human gingival fibroblasts to apoptosis. Therefore, this case report was aimed at the clinical evaluation of the proposed settings and treatment regimen in a very difficult situation of an immunocompromised patient with extensive changes and stagnation of symptoms for many weeks. A 65-year-old man, during his oncological treatment, was diagnosed with oral mucositis grade 3 according to the World Health Organization and National Cancer Institute scales. Due to pain sensation, long-lasting and not healing oral lesions, and problems with solid food intake, he was qualified for laser photobiomodulation therapy. For the management of oral lesions, a diode laser 635 nm (Smart^MPro, Lasotronix, Poland) was intraorally applied at an energy density of 4 J/cm², the 20 s of irradiation, the output power of 100 mW, and in continuous wave mode. Seven treatment procedures were performed two times a week using the spot technique in contact and non-contact mode. Within 21 days of monotherapy, all ailments disappeared. The patient was also able to reuse dental dentures and return to a solid diet. The obtained results confirm the efficiency of at least 3 PBM protocols. Our case shows that the use of PMB therapy contributes to faster healing of painful oral lesions in oncological patients, and thus the treatment time and return to the appropriate quality of life is shorter.

Cancers have a highly negative impact on the quality of life of paediatric patients and require an individualised oral treatment program for the phases of the disease. The aim of this study was to update existing research on oral care in children diagnosed with cancer. We carried out a literature search (in English, Spanish and Portuguese) in the Pubmed, Cochrane Library, EBSCO, WOS, SciELO, Lilacs, ProQuest, and SCOPUS databases and the websites of hospitals that treat childhood cancers. We found 114 articles and two hospital protocols. After review, we describe the interventions necessary to maintain oral health in children with cancer, divided into: phase I, before initiation of cancer treatment (review of medical record and oral history, planning of preventive strategies and dental treatments); phase II, from initiation of chemo-radiotherapy to 30–45 days post-therapy (maintenance of oral hygiene, reinforcement of parent/patient education in oral care, prevention and treatment of complications derived from cancer treatment); phase III, from 1 year to lifetime (periodic check-ups, maintenance, and reinforcement of oral hygiene, dental treatments, symptomatic care of the effects of long-term cancer treatment). The use of standardised protocols can avoid or minimise oral cancer complications and the side effects of cancer therapies. Full article

Medication-related osteonecrosis of the jaw (MRONJ) is a side effect of antiresorptive drugs. In this online survey, the awareness and knowledge of dentists regarding MRONJ was evaluated, and potential implications for oncologists are discussed. Questionnaires were emailed to dentists from Germany, Austria, Switzerland, and South Tyrol to evaluate disease-related knowledge and management. In addition to the overall score, a separate score was calculated for knowledge (maximum score: 15 points) and management (maximum score: 6 points) questions, and 1197 valid replies with completed questionnaires were received. The mean overall score was 10.45 ± 3.97 points, the mean knowledge score was 7.68 ± 3.05 points, and the mean management score was 2.76 ± 1.77 points. Factors influencing the outcome of the overall score were age, specialization, continuous professional education, and the number of dental screening exams in patients before antiresorptive therapy. Due to the considerable lack of knowledge regarding MRONJ among dentists, MRONJ patients and subjects at risk should be guided towards specialists for dental screening, treatment, and follow-up. This is important from an oncologic point of view to avoid any delay for treatment start of antiresorptives, and to reveal a potentially emerging osteonecrosis at an early stage, thus, avoiding the need for interruption or even cancellation of antiresorptive therapy.
