RESUMO
OBJECTIVES: To assess the prevalence of cutaneous and oral immune-related adverse events (irAEs) in cancer patients, risk factors for its development, and overall survival (OS). MATERIALS AND METHODS: This retrospective observational study which included 748 medical records of cancer patients who received immune checkpoint inhibitors (ICIs). Demographic and clinicopathological characteristics were collected and analyzed. RESULTS: Most patients were male (59.4%), with stage IV cancer (65%) and received pembrolizumab (46.7%). Four hundred fourteen (55.34%) patients developed cutaneous lesions, 84 (11.2%) developed oral mucosal lesions, and 70 (9.3%) developed xerostomia. The median time for irAEs development was 11 weeks for cutaneous and oral mucosal lesions, and 21.5 weeks for xerostomia. Patients who received PD-1 + CTLA-4 had a higher risk for developing cutaneous irAEs (p = 0.001), while those who underwent ICI and concurrent chemotherapy had a higher risk (p = 0.008) for developing oral mucosal lesions. Patients who presented oral and cutaneous irAEs had better OS than those who did not present (p = 0.0001). CONCLUSION: Cutaneous effects affected more than half of the patients, while oral effects and xerostomia were found in around 11% and 9% of patients, respectively. Concurrent chemotherapy and PD-1 + CTLA-4 were more associated with oral and cutaneous irAEs, respectively. Patients who developed such irAEs had better overall survival.
RESUMO
OBJECTIVE: This systematic review and meta-analysis aimed to compare the risk of recurrence and cancer progression after surgical treatment for oral potentially malignant disorders (OPMD) and precancerous lesions in different anatomical sites. MATERIALS AND METHODS: A comprehensive search was conducted in nine databases and grey literature. We included randomized controlled trials assessing surgical treatment efficacy for OPMD and precancerous lesions of cervical, vaginal, anal, and penile sites. Excision or ablation surgical treatments were considered. RESULTS: Overall, 12 studies met the eligibility criteria for oral leukoplakia (OL), proliferative verrucous leukoplakia, cervical intraepithelial neoplasia (CIN), vaginal intraepithelial neoplasia, and anal intraepithelial neoplasia (AIN). In qualitative analysis of surgical protocols, the lack of margin description impacts the clinical outcomes of OL and AIN, and the ablative protocols were heterogeneous in both OPMD and precancerous lesions. No significant difference in OL (risk ratio 0.82 [95% CI: 0.59-1.15]) and CIN (risk ratio 0.31 [95% CI: 0.09-1.09]) for recurrence was observed when cold-knife was compared with ablative protocols. OL exhibited higher recurrence and cancer progression rates compared to CIN and AIN. CONCLUSION: There is no difference in recurrence risk post-surgical treatment for OL and CIN. Surgical protocols for oral leukoplakia and CIN/AIN lack standardized approaches.
RESUMO
OBJECTIVES: To document the case of a patient who underwent several endodontic treatments due to a glandular odontogenic cyst misdiagnosed as an inflammatory periapical lesion. BACKGROUND: Glandular odontogenic cysts behave more aggressively, while others have an indolent course. There is limited information on this cyst in the gerodontologic literature. MATERIALS AND METHODS: A 76-year-old male patient presented with an asymptomatic expansive lesion in the anterior mandible resistant to several endodontic treatments. Cone-beam computed tomography revealed a multilocular osteolytic lesion measuring 6.0 × 4.0 cm, with cortical bone perforation. RESULTS: Histopathological analysis of a biopsy specimen was consistent with glandular odontogenic cyst. The patient underwent marginal mandibulectomy with preservation of the base of the mandible. CONCLUSION: A strict diagnostic process is important to avoid unwanted consequences, particularly in the geriatric population.

PURPOSE: This study aimed to evaluate the efficacy of 1W extraoral photobiomodulation (EOPBM) and to compare with our previous results of 2W EOPBM and intraoral photobiomodulation (IOPBM) protocols in the management of oral mucositis (OM) related to hematopoietic stem cell transplantation (HSCT). METHODS: A total of 30 patients underwent autologous or allogenic HSCT. Experimental protocol of 1W EOPBM was performed daily beginning in the first day of the conditioning regimen until 5 days after transplantation. The application areas included six points on the face and three points on the cervical area. Additional application of IOPBM was performed if patients had ulcered mucositis. Its severity was assessed daily according to WHO (World Health Organization) and NCI (National Cancer Institute) scales. Oral and oropharynx pains were scored daily by visual analogue scale (VAS). RESULTS: The 1W EOPBM protocol was well tolerated without any complaints. Of total, 13 patients were male and 17 were female and the mean age was 49.3 years old. Most patients (21 patients - 70%) received autologous HSCT, and 24 patients (80%) underwent myeloablative conditioning (MAC) regime and 6 patients (20%) reduced intensive conditioning regime. Nineteen patients (63.3%) developed OM according to WHO criteria, 3 patients grade I, 10 grade II and 6 grade III. NCI mucositis grades were similar to WHO grades. OM outcomes of 1W EOPBM were similar when compared to our previous groups and no significant differences were observed. No differences were found between pain and the protocols (1W EOPBM, IOPBM and 2W EOPBM). CONCLUSION: This 1W EOPBM protocol seemed to be as effective as IOPBM and 2W EOPBM in the prevention of OM in HSCT patients. In addition, we might assume that there is a window of application on EOPBM.

Immunotherapy with immune checkpoint inhibitors (ICIs) has transformed cancer treatment over the past decade, improving survival rates in numerous advanced cancers. Immune-related adverse events (irAEs) are common and can affect any organ system, with many of these toxicities being well-characterized with clear grading criteria and management approaches. There has been less emphasis on oral manifestations of irAEs. This review provides an overview of oral manifestations of irAEs, including mucosal and salivary gland toxicities, and proposes a grading system and management guidelines. irAEs are common treatment-related toxicities in patients treated with ICIs. Oral irAEs can range from asymptomatic white reticulations to life-threatening mucocutaneous reactions requiring aggressive management with corticosteroids and/or permanent discontinuation of ICIs. Oral healthcare providers should be prepared to identify and manage oral irAEs in collaboration with oncologists and other specialists.

OBJECTIVE: To determine the usefulness of Serum C-terminal telopeptide cross-link of type 1 collagen (sCTX) as a preoperative marker for predicting the risk of developing medication-related osteonecrosis of the jaws (MRONJ) after invasive oral surgery in patients on antiresorptive medication. MATERIALS AND METHODS: Two authors independently searched four electronic databases up to March 25, 2021, for case-control studies and prospective and retrospective cohort studies that assessed preoperative sCTX levels in patients taking antiresorptive medication who underwent oral surgery procedures. The main outcome was the number of MRONJ cases in patients with an sCTX value lower and higher than 150 pg/mL. Qualitative and quantitative data was extracted in tables and the risk of bias was assessed using the QUADAS-2 tool. Estimates of diagnostic accuracy were expressed as sensitivity, specificity, negative and positive likelihood ratio (LR - and LR +), and diagnostic odds ratio (DOR), with a 95% confidence interval (95%CI). The data were combined using random-effects models based on the inverse variance method. RESULTS: Seven studies were included in the meta-analysis. The results were as follows: sensitivity 57% (95%CI: 41-71%), specificity 72% (95%CI: 64-79%), LR + 2 (95%CI: 1.3-3.1), LR - 0.6 (95%CI: 0.4-0.9), and DOR 3.4 (95%CI: 1.5-7.7). CONCLUSIONS: The low overall performance of sCTX indicates that this parameter is not suitable for predicting MRONJ risk in patients on antiresorptive medication who need an oral surgery procedure. CLINICAL RELEVANCE: sCTX should not be considered a reliable preoperative marker to predict MRONJ development.

To compare the efficacy of intraoral and extraoral photobiomodulation (PBM) protocols for the prevention of oral mucositis (OM) in hematopoietic stem cell transplantation (HSCT) patients. A total of 60 patients was randomized into intraoral PBM (IOPBM) and extraoral PBM (EOPBM) groups. Both PBM protocols were well tolerated and no side effects were observed. EOPBM session times were one fourth of IOPBM durations. Of 60 patients, 35 (58.3%) developed ulcerated OM between day +3 and day +12. No intergroup difference was observed in OM healing times (p = 0.424). The lateral border of the tongue was the most common site affected in both groups. However, the incidence of mucositis on buccal mucosa was significantly reduced in the EOPBM group (p = 0.021). Young patients (OR.5.35, 95%CI 0.94-30.4, p = 0.058) and those who had received myeloablative conditioning (OR.55.1, 95%CI 2.69-1129.3, p = 0.009) were more likely to develop ulcerated OM, whereas autologous HSCT recipients (OR 0.079, 95% CI 0.009-0.67, p = 0.021) had a lower probability of developing ulcerated OM independent of PBM protocol. EOPBM protocol was as effective as IOPBM in the management of OM in HSCT patients, with the advantage of shorter treatment sessions. Trial registration number: RBR-7nww56. Date of trial registration submission: 30th September 2019.

OBJECTIVES: Describe the epidemiological profile of patients with oral squamous cell carcinoma (OSCC) around dental implants (DI), investigate the spectrum of clinical and pathological characteristics, and discuss the implications of diagnosis delay of these lesions. METHODS: Retrospective analysis of patients treated of OSCC adjacent to DI at A.C. Camargo Cancer Center between 2009 and 2020. RESULTS: Thirty one patients were identified, being women the majority (58.1%). The mean age of the patients was 68.8 years. Never smoker corresponds to 46.9% and never alcohol consumer to 54.9% of the sample. OPMD was reported in 45.2% of patients, affecting mainly women (78.5%). Leukoplakia (63.7%) followed by oral lichen planus (36.3%) was the most common OPMD found in women. OSCC adjacent to DI occurred in the inferior gingiva/alveolar mucosa in 48.3% of cases, and ulceration was the most common clinical appearance (87%). Peri-implantitis (PI) was initial clinical diagnosis in 16.1% of cases. CONCLUSIONS: Oral squamous cell carcinoma adjacent to DI was more common in women over 70 years old, non-smokers and non-drinker, and the majority had oral leukoplakia before the diagnosis of OSCC. OSCC may present clinical and radiographic features that resemble PI which can delay the diagnosis and impair the prognosis.

OBJECTIVES: The aim of the study was to evaluate the mandible cortical bone changes in patients with oral squamous cell carcinoma (OSCC). PATIENTS AND METHODS: Twenty patients who underwent some mandibular bone removal as part of the treatment of OSCC had bone samples collected in two parts: in the proximity of the tumor (BPT) and in the surgical margin (BEP). Cortical microarchitecture was analyzed trough micro-computed tomography, together with texture analysis, followed by microcrack evaluation in histological sections and gene expression of RANK, RANKL, OPG, and sclerostin by quantitative polymerase chain reaction. RESULTS: Bone surface was higher in BPT (0.005 ± 0.002 vs 0.004 ± 0.002, p = 0.01) compared with BEP. In BPT, the subset of patients without bone invasion presented higher anisotropy (0.83 ± 0.07) compared with the ones with bone invasion (0.70 ± 0.14) (p = 0.04). RANK, RANKL, OPG, and sclerostin were found to be downregulated in the majority of cases in both parts. There were significant correlations between the parameters of microarchitecture and gene expression analysis (p < 0.001 to p < 0.05), most of them related with OPG levels. CONCLUSION: The cortex in the mandible in the proximity of the tumor reveals more bone surface than the bone in the surgical margin, and the tumor invasion causes a decrease in anisotropy. RANK, RANKL, OPG, and sclerostin are downregulated in mandible, in both parts analyzed. Correlation tests revealed the association between cortical thickness, bone surface, anisotropy, porosity, bone mineral density, and OPG levels. CLINICAL RELEVANCE: The mandible cortical bone microarchitecture changes in the proximity of the squamous cell carcinoma lesion.

RESUMO
PURPOSE: The aim of this study was to evaluate the knowledge of Brazilian dentists (DEN) and dental students (DS) about bisphosphonates (BP) and bisphosphonate-related osteonecrosis of the jaw (BRONJ). METHODS: A convenience sample of 104 DEN and 100 DS was randomly selected and invited to answer a questionnaire. The questionnaire was structured on the basis of the main information about BP and the risk factors associated with the development of BRONJ. The data obtained were analyzed by the chi-square and Fisher's exact tests, considering significance of 5%. RESULTS: Seventy-five (72.1%) DEN and 75 (75%) DS did not know the BP cited in the questionnaire (p < 0.0001), and their commercial brand names were not recognized by 88 (84.6%) DEN and 86 (86%) DS (p < 0.0001). In the same way, 62 (59.6%) DEN (p = 0.04) and 58 (58%) DS (p < 0.0001) did not recognize BRONJ as an oral side effect of BP or point out oral conditions that were not associated with the use of BP. CONCLUSIONS: Practical initiatives, such as free lectures and workshops, must be taken to broaden the knowledge of DEN and DS about BP and thus contribute to the prevention of BRONJ.

PURPOSE: Bisphosphonates are drugs commonly used to treat osteoporosis, hypercalcemia of malignancy, and bone metastases. In some cases, its administration has been associated with osteonecrosis of the jaws. The management of medication-related osteonecrosis of the jaw (MRONJ) has not been completely elucidated, and its treatment can vary from no or limited surgery to more extensive surgery. The objective of the present study was to evaluate the efficacy of surgical therapy for patients presenting with MRONJ. PATIENTS AND METHODS: A retrospective study was conducted that evaluated all MRONJ cases resulting from bisphosphonate use and treated by surgery from 2006 to 2012. All patients underwent surgery under general anesthesia. RESULTS: A total of 33 patients with 46 MRONJ sites were evaluated. Most of the patients were women, with an age range of 39 to 83 years (mean 65.6 ± 10.6). Complete healing of the MRONJ region was observed in 40 of the 46 sites (87%), with partial improvement (symptom control and reduction of the exposed bone area) observed in 3 sites (6.5%), for a 93.5% clinical benefit rate. Of the remaining regions, 2 showed no significant changes, and 1 presented with a worse aspect compared with the patient's preoperative condition. Such cases were located in the posterior mandible region. The number of applications and type of bisphosphonate did not influence the treatment response. CONCLUSION: The surgical approach to treating MRONJ showed a high rate of clinical control. Therefore, surgery should be considered as a therapy for some cases of this condition.

OBJECTIVE: To present a case of oral syphilis in an old patient. BACKGROUND: Syphilis seems to be resurging mainly in the young. However, in the last twenty years, the elderly have become more susceptive to infectious diseases due to a more frequent use of sildenafil. CLINICAL REPORT: An 83-year-old man was referred to our clinic complaining of burning mouth. His medical history revealed papular lesions on chest and penis glans, which had been diagnosed and treated as scabiosis 2 months prior to our assessment. The intra-oral examination showed erosive and patch lesions on the bilateral lip commissures, the palate and the border of the tongue. Initially, oral herpes was suspected. However, both the serological test and the cytology were negative. Therefore, syphilis was hypothesised. Non-treponemic (VDRL) and treponemic tests (FTA-ABS) were reagent and secondary syphilis was confirmed. The treatment consisted of penicillin G benzathine 2.4 million IU/IM for 4 weeks. Both oral and skin lesions had complete remission. CONCLUSION: The present case illustrates that syphilis should be suspected in old patients with oral atypical lesions.

BACKGROUND: Most of the oral problems affecting patients in the ICU (intensive care unit) are conditions resulting from their general health status/immunosuppression, medications, and trauma due to tracheal intubation. Furthermore, microorganisms present in the oral cavity and oropharynx may be transported into the lungs resulting in pneumonia. PURPOSE: The objectives of this study were to evaluate the oral problems in patients in the ICU of a cancer center and describe the procedures performed by the dentists in such patients. METHODS: The sample consisted of 116 patients and 329 procedures performed in the period between May 2007 and July 2011 at A.C. Camargo Cancer Center. RESULTS: Oral mucositis was the main problem (20.3 %), especially in immunosuppressed patients (p < 0.001). Other most prevalent problems were candidiasis (16.6 %), bacterial biofilm (14.9 %), and xerostomia (7.18 %). The main procedures performed were clinical evaluation and medication prescription corresponding to 35.10 and 27.81 %, respectively. CONCLUSIONS: In conclusion, most of the patients presented oral problems related to side effects of oncological treatment. The dentist's participation in the ICU is important for the prevention, diagnosis, and treatment of oral problems.

OBJECTIVE: To assess the clinical features of exodontias performed in cancer patients who have been receiving intravenous bisphosphonates (BPs). STUDY DESIGN: This is a retrospective cohort study using a sample of 20 patients receiving BPs who had 62 teeth extracted. An univariate analysis was applied to calculate socket healing time (HT), comparing among exodontias performed according to cause, such as periodontal disease or caries, type of BP, and use of corticosteroid. In order to analyze the influence of each variable on HT, multiple statistical analyses were performed through logistic multiple regression. RESULTS: From the 62 tooth extractions performed, 5 exodontias had evolved to 4 sites of bisphosphonate-related osteonecrosis of the jaws (BOJ). Of another 57 exodontias without development of BOJ, HT was significantly better for tooth extraction performed in patients receiving corticosteroid (p= .01), for tooth extracted due to caries (p= .04), and for extractions under pamidronate (p= .03). Sockets after exodontias due to periodontal diseases had OR= 5.22 (95% CI 1.73-133.66, p=0.01) for delayed HT, exodontias performed under corticosteroid use had OR=0.04 (95% CI 0.01-0.40, p<0.001), and exodontias performed under zoledronate had OR=0.31 (95% CI 0.08-1.25, p=0.10). CONCLUSIONS: Exodontias performed in patients under BP therapy had a low rate of BOJ occurrence. Zoledronate and periodontal diseases influence delayed socket healing. Adjuvant antibiotics could be relevant procedures aimed at reducing the risk of BOJ development.

Benign fibro-osseous lesions with cystic degenerations have been scarcely reported in craniofacial bones and its unusual characteristics pose a diagnostic challenge. Here, we report a case of craniofacial fibrous dysplasia presenting a large cystic degeneration. A 55-year-old woman had a history of pain, slight asymmetry on the zygomatic region and ocular pressure. Computed tomography revealed on the right side, multiple craniofacial bones showing a ground glass aspect, associated with an extensive hypodense, unilocular, well circumscribed lesion in the maxilla, and smaller lesions in the sphenoid bone. After a surgical procedure performed in another service, there was a complete improvement in symptoms, and after 1 year, the patient remains stable, with no changes. In the literature review, thirty-three reported cases of the same association in the craniofacial region were found. The main symptoms were sudden increase in the lesion and pain, and the indication of intervention in cystic lesions was only indicated in symptomatic cases or functional deficit. The knowledge of the possibility of the association of benign fibro-osseous lesions and cystic degenerations in craniofacial bones is essential to perform a correct diagnosis and treatment for these patients, consequently avoiding unnecessary procedures. Key words:Craniofacial fibrous dysplasia, Fibrous dysplasia, Benign fibro-osseous lesions, Cystic degeneration.
RESUMO
INTRODUCTION: Radiotherapy remains one of the main treatments for head and neck cancer; however, it is accompanied by acute and chronic adverse effects. Use of three-dimensional (3D) oral stents to modulate radiation intensity to specific target areas have been developed to minimize these adverse effects. This study aimed to present a scoping review of studies published on 3D printing of oral stents and their clinical applicability. METHODS: MEDLINE/Pubmed, Scopus, Web of Science and CENTRAL Cochrane data bases were searched, studies selected, and data collected by three independent reviewers up to December 2022. The review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis-Extension for Scoping Reviews (PRISMA-ScR). RESULTS: The search resulted in 404 studies and 5 articles fulfilled the eligibility criteria and were considered for this review. Three-dimensional printed intraoral stents were produced for 56 patients with indication for radiotherapy. 3D-printed stents were well-tolerated by all tested patients and demonstrated great reproducibility of maxillomandibular relation, required less time for production and lower cost to manufacture. Two studies showed great protection of healthy tissues with 3D-printed stents during radiotherapy. CONCLUSIONS: Three-dimensional printing is promising for production of intraoral stents, however, more studies are needed to improve the technique and further investigate the safety and prevention of oral toxicities from radiotherapy.
