RESUMO
The management of oral potentially malignant disorders (OPMD) including oral leukoplakia (OL) is not currently structured according to agreed guidelines. The current report presents survey data gathered from Oral Medicine Practitioners (OMPs) in Europe and Australia and is aimed to investigate attitudes and practice in the diagnosis, risk stratification and treatment of OL. In the presence of a clinical provisional diagnosis of OL, respondents reported always undertaking biopsy in 83% of cases, with most OMPs also relying on diagnostic adjuncts. The potential for malignant transformation is almost invariably assessed through epithelial dysplasia status, with other biomarkers described in the literature used less often. Active treatment of OL was considered mandatory by 20% of OMPs, while others reserve treatment for selected cases only. OMPs are mostly driven to active treatment by lesion-related features which are frequently jointly considered including lesion site, clinical appearance and dysplasia status. Inconsistent assessment was observed regarding mild dysplasia, lesion size, presence of unavoidable trauma, exposure to tobacco and patient age. Frequently observed geographical variations were seldom statistically significant. In agreement with previous surveys, a lack of consensus around the management of OL was observed, supporting claims from learned academies and societies for treatment guidelines aiming to reduce inter-practitioner variability.

Oral Medicine is a young dental specialty born almost a century ago and deals with orofacial conditions not directly attributable to the most prevalent tooth pathologies such as dental caries or periodontal diseases. Presentations may reflect local disease or orofacial manifestations of more widespread pathology affecting other parts of the body. Due to its recency as a distinct discipline and to heterogeneous global settings, Oral Medicine has not yet achieved a shared scope and definition, as well as a recognized status across the globe. The current report presents survey data gathered from Oral Medicine practitioners in Europe and Australia and aimed to identify practitioner characteristics including demographics, training, clinical and research activity. As expected, Oral Medicine clinical practice commonly deals with conditions such as immune-mediated disorders, potentially malignant disorders, oral mucosal infections and chronic pain disorders, but geographical heterogeneities are observed. The present data, representative of current clinical practice, are valuable in order to understand the evolution of Oral Medicine as a distinct discipline and should be taken into consideration in order to create or update postgraduate training curricula able to meet the needs of future practitioners and the communities they serve.

BACKGROUND: A systematic review and meta-analysis were made of the incidence of recurrences in patients with proliferative verrucous leukoplakia (PVL) subjected to different types of treatment. METHODS: The study was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. A literature search was made in the Medline (PubMed), EMBASE, and Web of Science databases, together with a manual search, covering the period from 1985 to January 2020, with no language restrictions. Studies were included if they described treatments applied to at least 10 patients with the corresponding outcomes. Methodological quality was evaluated using Jadad scale and Newcastle-Ottawa tool. Global incidence was calculated by random effects meta-analysis using the Comprehensive Meta-analysis version 3.0 software. Publication bias was assessed using funnel plots and the Duval and Tweedie trim and fill method. RESULTS: Of the 922 identified articles, 12 were found to meet the inclusion criteria. Most of them presented moderate or low risk of bias. A total of 397 patients were analyzed. The mean age was 62.34 years and 248 were women (62.5%). The mean follow-up was 79.3 months. The most frequent treatment was surgical removal with a cold scalpel or laser (339 patients). A total of 232 subjects presented lesion recurrence. The combination of proportions global effect meta-analysis yielded a recurrence rate of 67.2% (95% CI: 48.3-81.8), with the absence of publication bias. CONCLUSIONS: There is not enough scientific evidence to conclude that any treatment strategy is able to reduce the recurrence in PVL.

OBJECTIVES: To investigate the available evidence on the malignant transformation (MT) of oral proliferative verrucous leukoplakia (PVL). MATERIAL AND METHODS: We searched six main electronic and three grey literature databases in a two-phase process. Cohort studies investigating MT of PVL were eligible for inclusion. The risk of bias (RoB) was assessed using a specific tool developed by the Joanna Briggs Institute. Proportion meta-analyses were performed using a random-effects model. RESULTS: Study selection resulted in the inclusion of 17 studies. The pooled proportion of MT was 43.87% (95% CI = 31.93-56.13). Females (64.02%, 95% CI = 54.87-72.75) were more affected by PVL than males (35.98%, 95% CI = 27.25-45.13). Gingiva (39.6%) and buccal mucosa (21.6%) were the most frequent PVL sites. No conclusive results were found between MT and sex or age distribution, tobacco, or alcohol consumption. Gingiva was the most common site for MT (39.9%), and the most frequent histopathological subtype was conventional squamous cell carcinoma (62.1%). Four studies were classified as low, nine as moderate, and four as high RoB. CONCLUSION: The MT pooled proportion was 43.87%. Among OPMDs, PVL has the highest risk to transform to malignancy. Development and agreement on diagnostic criteria for PVL would reduce the heterogeneity among future studies.

Oral potentially malignant disorders (OPMDs) are associated with an increased risk of occurrence of cancers of the lip or oral cavity. This paper presents an updated report on the nomenclature and the classification of OPMDs, based predominantly on their clinical features, following discussions by an expert group at a workshop held by the World Health Organization (WHO) Collaborating Centre for Oral Cancer in the UK. The first workshop held in London in 2005 considered a wide spectrum of disorders under the term "potentially malignant disorders of the oral mucosa" (PMD) (now referred to as oral potentially malignant disorders: OPMD) including leukoplakia, erythroplakia, proliferative verrucous leukoplakia, oral lichen planus, oral submucous fibrosis, palatal lesions in reverse smokers, lupus erythematosus, epidermolysis bullosa, and dyskeratosis congenita. Any new evidence published in the intervening period was considered to make essential changes to the 2007 classification. In the current update, most entities were retained with minor changes to their definition. There is sufficient evidence for an increased risk of oral cancer among patients diagnosed with "oral lichenoid lesions" and among those diagnosed with oral manifestations of 'chronic graft-versus-host disease'. These have now been added to the list of OPMDs. There is, to date, insufficient evidence concerning the malignant potential of chronic hyperplastic candidosis and of oral exophytic verrucous hyperplasia to consider these conditions as OPMDs. Furthermore, due to lack of clear evidence of an OPMD in epidermolysis bullosa this was moved to the category with limited evidence. We recommend the establishment of a global research consortium to further study the natural history of OPMDs based on the classification and nomenclature proposed here. This will require multi-center longitudinal studies with uniform diagnostic criteria to improve the identification and cancer risk stratification of patients with OPMDs, link them to evidence-based interventions, with a goal to facilitate the prevention and management of lip and oral cavity cancer.

OBJECTIVES: To explore the pathophysiology of proliferative verrucous leukoplakia, a rare oral disorder that exhibits high rates of recurrence and malignant transformation, through a RNAseq case-control study. MATERIAL AND METHODS: We obtained oral biopsies from 10 patients with verrucous leukoplakia lesions and from the mucosa of 5 healthy individuals for sequencing using RNAseq technology. Using bioinformatic methods, we investigated gene expression and enrichment differences between patients both with and without the disorder. We applied network biology methods to investigate functional relations among those genes that were differentially deregulated. RESULTS: We detected 140 differentially expressed genes with distinct roles in immune surveillance, tissue and organ morphogenesis, development, and organization. Of these 140 genes, 111 have been previously described as cancer expression biomarkers, being oral squamous cell carcinoma the most represented type of cancer among them. Of these 140 genes, 26 were prioritized for further investigation as biomarkers using larger sample sizes. CONCLUSIONS: The gene expression patterns of healthy and unhealthy patients differed in 140 genes whose deregulation has a functional impact on normal functioning of the immune system. This immune expression profile provides a plausible hypothesis to explain the transformation to oral squamous cell carcinoma observed in 6 of the 10 assayed cases. CLINICAL RELEVANCE: By determining the molecular bases of the proliferative verrucous leukoplakia disorder and identifying early biomarkers of malignancy, this can allow us to develop new treatment strategies.

BACKGROUND: Cytokines and chemokines have been analysed in patients with oral squamous cell carcinoma and potentially malignant disorders. We selected interleukin-6 (IL-6) because it is a multifunctional interleukin reported to be altered in potentially malignant oral disorders and in malignant lesions. To date, this has not been evaluated or tested in proliferative verrucous leukoplakia (PVL), however. OBJECTIVES: This study aimed to analyse the differences in serum and saliva IL-6 levels among patients with PVL, oral squamous cell carcinoma (OSCC) and healthy controls and to examine the relationship between salivary IL-6 levels and the extent of the verrucous area. METHODS: Using an enzyme-linked immunosorbent assay, we determined the serum and saliva IL-6 levels in three groups: 20 patients with PVL, 20 with OSCC and 20 healthy controls. RESULTS: There were significant (p < 0.01) differences in the serum and saliva IL-6 levels among the three groups and among the three grades of extent of the verrucous areas (p = 0.01). In the OSCC group, there was a significant difference in the saliva IL-6 levels between patients with and without lymph node metastasis at diagnosis (p = 0.02). CONCLUSIONS: We found that patients with OSCC had the highest salivary and serum IL-6 levels, while PVL had lower values than OSCC, but higher than the controls, and these altered levels were associated with the extent of the verrucous areas. CLINICAL RELEVANCE: Salivary and plasma IL-6 are altered in patients with PVL, with more extensive verrucous areas being associated to the highest IL-6 levels. This could be a significant tool for monitoring patients with PVL, their progression to more advances stages and their recurrences.

BACKGROUND: To analyze the presence of salivary Epstein-Barr virus (EBV) DNA in oral squamous cell carcinoma and potentially malignant oral disorders. MATERIAL AND METHODS: Three groups were studied: Group 1 (12 oral squamous cell carcinomas (OSCC)), Group 2 (12 potentially malignant oral disorders (PMD)) and Group 3 (47 healthy controls). EBV DNA salivary analysis was performed by PCR. RESULTS: The highest percentage of positive salivary EBV DNA corresponded to the OSCC group (58.3%), followed by the PMD group (41.7%) and the controls (40.4%). The differences between groups were not statistically significant, however (p>0.05). CONCLUSIONS: Salivary EBV DNA was more prevalent in OSCC than in PMD or the controls.

OBJECTIVES: The objectives of this study are to describe the distinctive characteristics of extra-nodal B-cell non-Hodgkin's lymphomas (BNHLs) located in the head and neck in a series of patients, to discuss patient survival, and to compare the oral versus the non-oral locations of the extra-nodal BNHLs of the head and neck. MATERIAL AND METHODS: We studied 68 patients with BNHL of the head and neck. We analyzed the clinical and survival characteristics. Additionally, we performed Kaplan-Meier and Cox regression analyses to determine the influence of the different factors on survival. RESULTS: This study included 68 non-nodal lymphomas; 30 lymphomas (31.9%) were located intraorally, with the gingiva as the most frequent location. The oral lymphomas in stages 1 and 2 showed a prevalence of 60% (18/30). The Kaplan-Meier analysis showed that the stage of disease and the oral versus non-oral extranodal lymphomas were significant prognostic factors (p<0.05). However, the multivariate Cox analysis indicated that only complete remission and oral versus non-oral location were significant prognostic factors (p<0.01). CONCLUSIONS: The gingiva was the most common location of the intraoral lymphomas. Complete remission and non-oral location were the only significant survival factors in the multivariate Cox regression analysis.

The authors have collaborated with many colleagues in several countries in formulating a useful and practical clinical tool for evaluating oral mucosal findings on routine examination. Consideration of several factors including history, evolution of positive findings and clinical information allows placement of examination results into one of three categories which are graded by a color scheme along a spectrum of concerns (green to red, or no concern to serious concern). Afforded to the clinician is a straightforward grading system as a starting point for office end clinic use for all patients.

PURPOSE: An analysis was performed of the clinical and epidemiologic characteristics of a group of patients diagnosed with oral metastases of distant primary tumors or unknown primary malignancies. MATERIAL AND METHODS: The study series consisted of 16 patients with oral metastatic lesions seen in the Department of Stomatology and Maxillofacial Surgery, Valencia University General Hospital (Valencia, Spain) that had been diagnosed in the previous 15 years. A retrospective analysis was made of patient age and gender, clinical characteristics of metastatic lesions, location of the primary tumor, and time elapsed from diagnosis to the death of a patient. RESULTS: There were 13 male and 3 female patients (mean age, 58.8 years). Ten patients had been diagnosed previously and were being treated for a primary tumor; 2 patients were diagnosed with a primary malignancy in the department; and 4 patients presented with an unidentified primary tumor (metastatic disease diagnosed from biopsy study). The predominant clinical presentation was mixed soft tissue and bone metastases followed by solely soft tissue lesions and solely bone lesions. Some patients showed no apparent oral lesions. Primary malignancies originated mainly from the lung followed by the prostate, gastrointestinal tract, thyroid gland, breast, and liver. Mean survival from diagnosis of oral metastases was 8.25 months. CONCLUSION: Oral metastatic lesions are infrequent, can affect male and female patients equally, can manifest at any age, and may constitute the first manifestation of a still unidentified primary malignancy. According to the literature, bone metastases are more common than soft tissue metastases. Nevertheless, in the present series, there was a clear male predominance, and the oral metastases showed a predominance of mixed presentations followed by solely soft tissue lesions and solely bone metastases.

OBJECTIVE: To review the pseudotumors and tumors of the temporomandibular joint (TMJ) published in journals included in Journal Citation Reports (JCR), and to evaluate whether there are clinical and radiological signs capable of differentiating between pseudotumors and tumors and between malignant and benign tumors. MATERIAL AND METHODS: A systematic Medline search was made of clinical cases of tumors and pseudotumors of the TMJ covering a 20-year period and published in journals included in JCR. Only cases with histological confirmation were included. A description is provided of the general characteristics of TMJ tumors, with comparison of the clinical, diagnostic, therapeutic and evolutive variables referred to pseudotumors, benign tumors and malignant tumors. RESULTS: We identified 285 TMJ tumors published in 181 articles of 15 journals. The most frequent lesions were pseudotumors (synovial chondromatosis, pigmented villonodular synovitis, eosinophilic granuloma and osteochondroma). The mean age was 42 years and one month ± 16 years and two months. Tumors were more common in females. The mean time from symptoms onset to consultation was 30 months and 8 days ± 41 months and 9 days, and almost 19.6% of the cases initially had been diagnosed and treated as TMJ dysfunction. The most frequent clinical manifestations were pain, swelling and the limitation of joint movements. The most common radiological findings in the case of benign and malignant lesions were radiopacities and radiotransparencies, respectively. No panoramic X-ray alterations were observed in 14.6% of the benign tumors and in 7.7% of the malignant lesions. Surgery was the usual form of treatment. Sequelae were recorded in 18.2% of the cases, with tumor relapse in 9.1%. The four-year survival rate in the case of malignant tumors was 72.2%.

INTRODUCTION: This preliminary study compared the epidermal growth factor receptor (EGFR) copy number in patients with potentially malignant oral disorders (PMODs) and oral squamous cell carcinoma (OSCC). MATERIAL AND METHODS: Group 1 comprised 20 patients with oral leukoplakia and group 2 comprised 19 cases of OSCC. We estimated the EGFR copy number in both groups using real-time reverse-transcription polymerase chain reaction assays. We used laser microdissection (LMD) for EGFR amplification, and overexpression was performed. RESULTS: The EGFR copy number was higher in group 2 (9.1 ± 6.2) than in group 1 (3.8 ± 1.5). The greatest copy number was found in the non-homogeneous leukoplakias, but the difference in homogeneous cases was not significant (Mann-Whitney test, P>0.05). In group 2, the EGFR copy number was higher in advanced stages than in early stages, but again lacked statistical significance. CONCLUSIONS: The EGFR copy number may be a useful biomolecular marker to differentiate PMODs from OSCC. The EGFR was higher in non-homogeneous leukoplakias and in the advanced stages of OSCC.

OBJECTIVE: To compare the risk factors and clinical manifestations of patients with temporomandibular disorders (TMDs) diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) (axis I) versus an age and gender matched control group. STUDY DESIGN: A total of 162 patients explored according to the RDC/TMD (mean age 40.6±18.8 years, range 7-90; 11.1% males and 88.9% females) were compared with 119 controls, measuring differences in TMD risk factors (sleep disturbances, stress, psychoactive medication, parafunctions, loss of posterior support, ligament hyperlaxity) and clinical variables (joint sounds, painful muscle and joint palpation, maximum aperture). RESULTS: Myofascial pain (MFP) (single or multiple diagnoses) was the most frequent diagnosis (42%). The most common diagnostic combination was MFP plus arthralgia (16.0%). Statistically significant differences were observed in clenching (OR 2.3; 95%CI: 1.4-3.8) and in maximum active aperture (MAA) on comparing the two groups both globally (TMD vs. controls) (patients 36.7±8.6 mm, controls 43.1±5.8 mm; F=45.41, p=0.000) and on comparing according to diagnostic categories. MFP explained most of the observed differences in the risk factors: stress perception (OR=1.98;I.C.:1.01-3.89), psychoactive medication (OR=2.21; I.C.:1.12-4.37), parafunctions (OR=2.14;I.C.:1.12-4.11), and ligament laxity (OR=2.6;I.C.:1.01-6.68). Joint sounds were more frequent in patients with MFP (39.7% vs. 24.0%; χ²=4.66; p=0.03), and painful joint palpation was more common in patients with disc displacement with reduction (DDWR)(15.9% vs. 5.0%; χ²= 5.2; p=0.02) and osteoarthrosis (20.8% vs. 5.0%; χ²=7.0; p=0.008). CONCLUSIONS: There is a high prevalence of signs and symptoms of TMDs in the general population. Significant differences are observed in clenching and MAA between patients and controls considered both globally and for each diagnostic category individually. The analyzed risk factors (except loss of posterior support) show a statistically significant OR for the diagnosis of MFP.

AIM: The aim of this preliminary study was to detect cytological changes in the oral mucosa after using a mouth wash with alcohol. MATERIAL AND METHODS: A prospective double-blind, controlled study was performed, for 6 months. Group 1 consisted of 30 subjects who used a mouth rinse with 26.9% of alcohol [Listerine] and Group 2 consisted of 30 subjects who used a mouth rinse with the same ingredients but with no alcohol. We obtained three cytological samples from the oral mucosa. The presence of cytological atypia, binucleation and karyorrhesis, and type of cells were studied. We also used a fluorescent in situ hybridization technique (FISH) in 15 samples in each group, for the micronucleus. RESULTS: We found no clinical mucosal alteration after using the mouth wash at the end of the study in either group. We observed no cytological differences between the groups at the end of the study (p>0.05). Regarding the study of the micronucleus by FISH, we observed no significant difference between the groups (p>0.05). CONCLUSIONS: Our results showed no cytological alteration in patients using a mouth rinse with alcohol, but these findings should be considered preliminary results, to be confirmed in a greater sample of patients.

OBJECTIVE: A study is made of the clinical course of patients with episodic cluster headache following the injection of corticosteroids in the proximity of the sphenopalatine ganglion of the affected side. STUDY DESIGN: A retrospective observation study was made corresponding to the period between 2006 and 2010. Patients with episodic cluster headache received corticosteroid infiltrations in the vicinity of the sphenopalatine ganglion. Data were collected to assess the clinical course, quantifying pain intensity and quality of life. A total of 23 patients (11 women and 12 men) with a mean age of 50.4 years (range 25-65) were included. Forty percent of the patients had undergone dental extractions in the quadrant affected by the pain, before the development of episodic cluster headache, and 37.8% underwent extractions in the same quadrant after appearance of the headache. RESULTS: Most of the patients suffered 1-3 attacks a day, with a duration of pain of between 31-90 minutes. The mean pain intensity score during the attacks at the time of the first visit was 8.8 (range 6-10), versus 5.4 (range 3-9) one week after the first corticosteroid injection. On the first visit, 86.9% of the patients reported unbearable pain, versus 21.7% after one week, and a single patient after one month. CONCLUSIONS: The evolution of episodic cluster headache is unpredictable and variable, though corticosteroid administration clearly reduces the attacks and their duration.

OBJECTIVES: To determine whether there is a relationship between the total BP dose administered and the variations in serum CTX concentration. STUDY DESIGN: The study included 50 patients requiring dental implant surgery and treated with oral BPs, seen in an Oral Surgery and Implantology Unit between January 2007 and June 2009. The patients were divided into two groups: those in which the medication was not suspended before obtaining the laboratory test sample, and those patients referred from other dental clinics in which BPs was suspended before reporting to our Unit. The total drug dosage administered and the total dose per kilogram body weight were evaluated for comparison with serum CTX. The data obtained were correlated to the osteonecrosis risk table developed by Marx et al. in 2007. RESULTS: There were no significant differences between the two groups in relation to the total administered dose and the dose in mg/kg b.w. Likewise, in both groups no relationship was observed between the serum CTX value and the total administered dose or the dose in mg/kg b.w. No differences were found between the two patient groups regarding chemical osteonecrosis risk based on the criteria of Marx et al. CONCLUSIONS: No relationship was observed between the oral BP dose administered (total dose or expressed in mg/kg b.w.) and serum CTX concentration, and suspension of the medication did not influence the serum CTX levels.

Osteonecrosis of the jaw is an uncommon but potentially serious complication of bisphosphonate therapy in multiple myeloma. Previous studies showed that the presence of one or two minor alleles of the cytochrome P450, subfamily 2C polypeptide 8 gene (CYP2C8) polymorphism rs1934951 was an independent prognostic marker associated with development of osteonecrosis of the jaw in multiple myeloma patients treated with bisphosphonates. The aim of this study was to validate the frequency of SNP rs193451 in 79 patients with multiple myeloma. In 9 (22%) patients developing osteonecrosis of the jaw, a heterozygous genotype was found, in contrast with those who did not develop osteonecrosis of the jaw (n=4, 11%) or healthy individuals (n=6, 13%). We found no differences in the cumulative risk of developing osteonecrosis of the jaw between patients homozygous and heterozygous for the major allele. We were unable to confirm a significant association between this polymorphism and the risk of developing osteonecrosis of the jaw.

OBJECTIVES: The purpose of this study was to make a descriptive approximation of the therapeutic management of the different dental interventions in clinical practice today, and to analyze the degree of consensus among the specialists participating in the study. STUDY DESIGN: A total of 447 odontologists, stomatologists or maxillofacial surgeons from 43 Spanish provinces participated in the study. The study sample consisted of patients aged 18 years old or over attending the clinic for a dental intervention. The type of intervention carried out and treatments administered before and after the intervention were recorded. At 24 hours after the intervention, intensity of pain experienced by the patient, rescue therapy administered for pain relief, sleep affectation, the appearance of adverse events or complications of the intervention, and treatment compliance were also recorded. RESULTS: Data corresponding to 4,194 patients were analyzed, of whom 53.2% were women (2,232). The mean age was 42.6 years (95%CI 42.2- 43). The most frequent interventions corresponded to: oral surgery (66.4%), endodontics (17.3%) and periodontal treatment (4.6%). A total of 43.2% of the patients were taking some medication before the intervention: anticoagulants (2.5%), antibiotics (33%), pain relief and/or anti-inflammatory agents (23%) and other drugs (7.6%); 16.6% were receiving combined treatment with antibiotics and analgesics and/or anti-inflammatory agents before the intervention. Treatments prescribed to the patient for the 24 hours following the intervention corresponded to only one analgesic and/or anti-inflammatory in 18%, and a combination of analgesics and/or anti-inflammatories in 77.1%. Antibiotics were prescribed in 39.7%. CONCLUSIONS: Different patterns of therapeutic management by the specialists were noted depending on the type of intervention carried out. The use of analgesics and/or anti-inflammatories depended on the severity of pain expected with each intervention and the administration of antibiotics was related to the prevention of local infections.

OBJECTIVE: To determine whether a series of diseases of the oral mucosa - Sjögren syndrome, ectodermal dysplasia, epidermolysis bullosa and lichen planus - reduce the survival rate of dental implants. MATERIAL AND METHOD: A Medline search was carried out using the key words: " Sjögren syndrome ", "ectodermal dysplasia ", "epidermolysis bullosa ", "lichen planus " and "dental implants ", including those publications involving clinical series comprising more than one patient with the mentioned disorders and treated with dental implants, in the last 10 years. RESULTS: The study included three articles involving patients with Sjögren syndrome subjected to dental implant treatment, representing a total of 12 patients and 86 implants, with a mean pondered success rate of 86.33%. As regards ectodermal dysplasia, we included 14 articles, of which 11 corresponded to clinical series, two were reviews and one constituted a survey of dental professionals. The percentage success rate of the implants varied between 35.7-100%. In relation to epidermolysis bullosa, we included 6 articles corresponding to clinical series, with a total of 16 patients and 92 implants, and a success rate between 75-100%. In the case of oral lichen planus we found only two articles corresponding to clinical case series, with a total of 5 patients and 14 implants, and an implant survival rate of 100%. CONCLUSIONS: Based on our review of the literature, dental implant rehabilitation in patients of this kind is seen to be a valid treatment option, with a high percentage success rate. Long-term patient follow-up is essential in order to periodically monitor the condition of the disease and of the implants.
