Clinical and radiologic treatment outcomes of implant presence tirggered-MRONJ: Systematic review of literature.

BACKGROUND: The present systematic review evaluated clinical and radiographic features and treatment outcomes of peri-implantitis-induced medication-related osteonecrosis of the jaws (Pi-MRONJ). MATERIALS AND METHODS: Literature search was performed in PubMed/MEDLINE, Cochrane CENTRAL, Web of Science, and Scopus databases. Studies reporting Pi-MRONJ were included. No time restrictions were applied. RESULTS: In total, 571 articles were retrieved, and 24 articles were included in the final review. Study population consisted of 111 patients (70% pharmacologically treated for osteoporosis and 30% for oncologic disease). Pi-MRONJ was characterized by pain, bone exposure and suppuration, and involved a single implant in 55 cases, two implants in 37 cases, three implants in 10 cases, and more than four implants in nine cases. Most of the lesions were assigned Stage II and III. MRONJ developed on average 46.5 ± 33.2 months following implant placement. Sixty-one lesions were surgically treated with implant removal and debridement of the surrounding necrotic bone. Complete wound healing was observed in 85% of cases. CONCLUSIONS: The presence of dental implants in patients treated with antiresorptive drugs should be considered as a potential risk factor for MRONJ onset. In cases of periimplantitis with delayed wound healing following nonsurgical therapy, the clinician should rule out the presence of Pi-MRONJ.

Early periodontal wound healing after chlorhexidine rinsing: a randomized clinical trial.

OBJECTIVES: This single-center randomized, parallel design, clinical trial with a 2-week follow-up involved patients affected by periodontitis undergoing periodontal surgery. The aim was to evaluate periodontal surgical wound healing with the use of chlorhexidine-based mouth rinses versus an untreated control group. MATERIALS AND METHODS: Periodontal surgery was performed following a standardized protocol. Patients were randomly prescribed i) chlorhexidine (CHX) + anti-discoloration system (ADS) + hyaluronic acid (HA), ii) CHX + ADS or iii) no treatment (control group). Plaque score, gingival inflammation, and Early Healing Index (EHI), assessing the degree of wound closure and the presence of fibrin and necrosis, were evaluated at 3, 7 and 14 days after surgery. RESULTS: In total, 33 patients were enrolled. Patients were comparable at baseline for all measured clinical parameters. At 3-days wound healing was significantly improved in all patients treated with CHX + ADS-based mouth rinses with a lower EHI score at the interdental papillae compared with control group (p < 0.01). CHX + ADS + HA group presented improved healing across all time points in terms of EHI, plaque containment, and gingival inflammation when compared to control group (p < 0.01). CONCLUSIONS: The usage of CHX-ADS following periodontal surgery improved early wound healing, reduced plaque accumulation and gingival inflammation. During the early post-operative period the adjunct of HA further improved soft tissue closure. CLINICAL RELEVANCE: This study aims at evaluating the response of gingival tissues to mouth rinsing with chlorhexidine and anti-discoloration system (CHX + ADS) or CHX + ADS + hyaluronic acid (CHX + ADS + HA) versus no rinse in terms of healing of the periodontal surgical wound. CHX + ADS mouth rinses enhanced early soft tissue closure after periodontal surgery and contributed to the reduction in plaque accumulation and gingival inflammation. The adjunct of HA may be beneficial especially in the early post-operative period. CHX + ADS administration following periodontal surgery may improve soft tissue healing in the first two post-operative weeks.

Complications and treatment errors in nonsurgical periodontal therapy.

Nonsurgical periodontal therapy can be subject to iatrogenesis, which includes all the complications directly or indirectly related to a treatment. These complications include both operator-dependent harms and errors and the consequences and adverse effects of the therapeutic procedures. The complications arising following nonsurgical periodontal treatment can be categorized as intraoperative and postoperative and can affect both soft and hard tissues at an intra-oral and extraoral level. Soft-tissues damage or damage to teeth and restorations can occur while performing the procedure. In the majority of cases, the risk of bleeding associated with nonsurgical therapy is reported to be low and easily controlled by means of local hemostatic measures, even in medicated subjects. Cervicofacial subcutaneous emphysema is not a frequent extraoral intraoperative complication, occurring during the use of air polishing. Moreover, side effects such as pain, fever, and dentine hypersensitivity are frequently reported as a consequence of nonsurgical periodontal therapy and can have a major impact on a patient's perception of the treatment provided. The level of intraoperative pain could be influenced by the types of instruments employed, the characteristics of tips, and the individual level of tolerance of the patient. Unexpected damage to teeth or restorations can also occur as a consequence of procedural errors.

Efficacy of adjunctive measures in peri-implant mucositis. A systematic review and meta-analysis.

AIM: To answer the following PICO question: In systemically healthy humans with peri-implant mucositis, what is the efficacy of patient-performed or administered (by prescription) measures used adjunctively to submarginal instrumentation, as compared to submarginal instrumentation alone or combined with a negative control, in terms of reducing bleeding on probing (BOP), in randomized controlled clinical trials (RCTs) with at least 3 months of follow-up? MATERIALS AND METHODS: Three databases were searched until April 2022. Weighted mean differences (WMDs) with 95% confidence intervals (CIs) and predictive intervals were calculated. RESULTS: Sixteen parallel RCTs corresponding to 14 studies with low/moderate risk of bias were included. Test groups showed greater reductions in BOP (%) than control groups (nstudies  = 16; npatients  = 650; WMD = 14.25%; 95% CI [9.06-19.45]; p < .001; I2  = 98.7%). The greatest WMD in BOP reductions (%) were obtained by antiseptics (ns  = 5; np  = 229; WMD = 22.72%; 95% CI [19.40-26.04]; p < 0.001; I2  = 94.8%), followed by probiotics (ns  = 6; np  = 260; WMD = 12.11%; 95% CI [3.20-21.03]; p = .008; I2  = 93.3%) and systemic antibiotics (ns  = 3; np  = 101; WMD = 5.97%; 95% CI [1.34-10.59]; p = .012; I2  = 58.1%). Disease resolution was scarcely reported (n = 6). CONCLUSIONS: Significant clinical improvements can be obtained when professional submarginal instrumentation is combined with patient-performed or administered (by prescription) adjunctive measures, although a complete disease resolution may not be achieved.

Leisure-time and occupational physical activity demonstrate divergent associations with periodontitis: A population-based study.

AIM: To evaluate the association between leisure-time/occupational physical activity (LTPA/OPA) and periodontitis in a nationally representative sample of the U.S. MATERIALS AND METHODS: Data from 10,679 adults were retrieved from NHANES 2009-2014 database. Physical activity was assessed through the Global Physical Activity Questionnaire, and accordingly, subjects were classified as performing either high or low LTPA/OPA. Periodontal status was assessed through a full-mouth periodontal examination, and subjects were classified according to the AAP/CDC criteria (no, mild, moderate, or severe periodontitis). Simple and multiple regression analyses were applied to study the association between LTPA/OPA and periodontitis/severe periodontitis. RESULTS: Multiple regression analyses identified high LTPA as a protective indicator for periodontitis (odds ratio [OR] = 0.81; 95% confidence interval [CI]: 0.72-0.92), while high OPA was found to be a significant risk indicator (OR = 1.16; 95% CI: 1.04-1.30). The combination low LTPA/high OPA showed a cumulative independent association with periodontitis (OR = 1.47; 95% CI: 1.26-1.72). Moreover, both high LTPA (OR = 0.72; 95% CI: 0.58-0.90) and high OPA (OR = 1.29; 95% CI: 1.09-1.53) were significantly associated with stronger estimates of severe periodontitis; the same was observed for the combination of low LTPA/high OPA (OR = 1.66; 95% CI: 1.29-2.15). CONCLUSIONS: LTPA and OPA showed divergent associations with periodontitis.

Acute-phase response following one-stage full-mouth versus quadrant non-surgical periodontal treatment in subjects with comorbid type 2 diabetes: A randomized clinical trial.

AIM: To compare the level of inflammatory markers and endothelial function 24 h (Day 1) and 90 days (Day 90) after conventional quadrant-wise scaling and root planing (Q-SRP) versus one-stage full-mouth SRP (FM-SRP) in patients affected by type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: Patients affected by periodontitis and T2DM were randomly allocated to receive FM-SRP or Q-SRP and followed up at Day 1 and Day 90. Serum samples, vital signs, and flow-mediated dilation (FMD) parameters were collected at baseline, Day 1, and Day 90. Periodontal variables were collected at baseline and Day 90. The primary outcome was the C-reactive protein (CRP) concentration at Day 1 after periodontal treatment. Student's t-test for independent samples was used for between-group comparisons (Mann-Whitney U test for non-normal data), while analysis of variance with post hoc Tukey tests (Kruskal-Wallis and Dunn tests for non-normal data) were used for intra-group comparisons. RESULTS: Forty subjects were included in the study. FM-SRP produced a significant increase in CRP and a significant reduction in FMD at Day 1 compared to Q-SRP (p < .05). The absolute change in HbA1c (mmol/mol) from baseline to Day 90 was significantly improved in the Q-SRP (ΔHbA1c = -1.59 [SD = 1.20]) compared to the FM-SRP group (ΔHbA1c = -0.8 [SD = 0.95]) (p = .04). CONCLUSIONS: FM-SRP triggers a robust acute-phase response at 24 h after treatment compared to Q-SRP. Such systemic acute perturbations may offset the beneficial systemic effects of periodontal treatment in terms of HbA1c reduction and improvement in endothelial function in T2DM subjects.

Prevention and management of peri-implant mucositis and peri-implantitis: A systematic review of outcome measures used in clinical studies in the last 10 years.

OBJECTIVES: To evaluate outcome measures, methods of assessment, and analysis in clinical studies on the prevention and management of peri-implant mucositis and peri-implantitis. METHODS: Systematic electronic searches (CENTRAL/MEDLINE/SCOPUS) up to April 2021 were conducted to identify longitudinal clinical studies with ≥10 patients on either the prevention or management of peri-implant diseases. Outcome measures of this analysis were the choice of outcome measures, methods of assessment, and analytical methods. Risk of bias was evaluated according to study design. Data were extracted into evidence tables and outcomes were analysed in a descriptive manner. RESULTS: The analysis of the 159 selected studies revealed that probing pocket depth (PPD) and bleeding/suppuration on probing (BOP) were reported in 89% and 87% of all studies, respectively. Additional outcome measures included plaque scores (reported in 64% of studies), radiographic outcomes (49%), soft tissue dimensions (34%), and composite outcomes (26%). Adverse events (8%) and patient-reported outcomes (6%) were only rarely mentioned. A primary outcome measure was clearly defined only in 36% of studies. Data on PPD, radiographic outcomes, and soft tissue dimensions were primarily reported as mean values and rarely as frequency distributions. For radiographic outcomes and soft tissue dimensions, it was frequently unclear how clustered data were handled. CONCLUSIONS: PPD and BOP were routinely reported in studies on the prevention and management of peri-implant mucositis and peri-implantitis, while composite outcomes, adverse events, and patient-reported outcomes were only infrequently described.

Healthy lifestyles are associated with a better response to periodontal therapy: A prospective cohort study.

AIM: To evaluate the association between lifestyle behaviours and clinical periodontal outcomes following Steps 1/2 of periodontal therapy. METHODS: A total of 120 subjects with untreated Stage II/III periodontitis participated in this study. At baseline, questionnaires were administered to assess the following lifestyle behaviours: adherence to Mediterranean diet (MD), physical activity (PA) and stress levels, sleep quality, smoking and alcohol use. Participants received Steps 1/2 of periodontal therapy and were re-evaluated after 3 months. A composite outcome of the endpoint of therapy (i.e., no sites with probing pocket depth [PPD] ≥4 mm with bleeding on probing, and no sites with PPD ≥ 6 mm) was regarded as the primary outcome. Simple and multiple regression analyses were used to evaluate the association between lifestyle behaviours and clinical periodontal outcomes. Disease severity at baseline, body mass index, diabetes, household disposable income and plaque control were considered as confounders. RESULTS: Multiple regression analyses showed significantly lower odds of achieving the endpoint of therapy in subjects with poor sleep quality (odds ratio [OR] = 0.13; 95% confidence interval [CI]: 0.03-0.47; p < .01), smoking (OR = 0.18; 95% CI: 0.06-0.52; p < .05) and alcohol use above the suggested intake (OR = 0.21; 95% CI: 0.07-0.63; p < .01). Subjects with a combination of 'unhealthy lifestyles' (low adherence to MD and low PA levels and high levels of stress and poor sleep quality) showed higher proportions of residual PPD≥6 mm (MD = 1.51; 95% CI: 0.23-2.80; p < .05) and lower odds of achieving the endpoint of therapy (OR = 0.85; 95% CI: 0.33-0.99; p < .05) at re-evaluation. CONCLUSIONS: Subjects with unhealthy lifestyle behaviours showed worse clinical outcomes 3 months after Steps 1/2 of periodontal therapy.

Association between periodontal diseases and cardiovascular diseases, diabetes and respiratory diseases: Consensus report of the Joint Workshop by the European Federation of Periodontology (EFP) and the European arm of the World Organization of Family Doctors (WONCA Europe).

AIM: To explore the implications for dentists and family doctors of the association between periodontal and systemic diseases and the role of dentists and family doctors in managing non-communicable diseases (NCDs) and promoting healthy lifestyles. MATERIALS AND METHODS: The consensus reports of the previous Focused Workshops on the associations between periodontitis and diabetes (2017) and periodontitis and cardiovascular diseases (2019) formed the technical reviews to underpin discussions on both topics. For the association with respiratory diseases, a systematic review was specifically commissioned for the Workshop discussions. Working groups prepared proposals independently, and then the proposals were discussed and approved at plenary meetings. RESULTS: Periodontitis is independently associated with cardiovascular diseases, diabetes, chronic obstructive pulmonary disease (COPD), obstructive sleep apnea and COVID-19 complications. Dentists and family doctors should collaborate in managing NCDs, implementing strategies for early detection of periodontitis in primary care centres and of cardiovascular diseases or diabetes in dental settings. Family doctors should be informed about periodontal diseases and their consequences, and oral health professionals (OHPs) should be informed about the relevance of NCDs and the associated risk factors. CONCLUSIONS: Closer collaboration between OHPs and family doctors is important in the early detection and management of NCDs and in promoting healthy lifestyles. Pathways for early case detection of periodontitis in family medicine practices and of NCDs in dental practices should be developed and evaluated.

Relevant domains, core outcome sets and measurements for implant dentistry clinical trials: The Implant Dentistry Core Outcome Set and Measurement (ID-COSM) international consensus report.

AIM: Lack of consistently reported outcomes limits progress in evidence-based implant dentistry and quality of care. The objective of this initiative was to develop a core outcome set (COS) and measurements for implant dentistry clinical trials (ID-COSM). MATERIALS AND METHODS: This Core Outcome Measures in Effectiveness Trials (COMET)-registered international initiative comprised six steps over 24 months: (i) systematic reviews of outcomes reported in the last 10 years; (ii) international patient focus groups; (iii) a Delphi project with a broad range of stakeholders (care providers, clinical researchers, methodologists, patients and industry representatives); (iv) expert group discussions organizing the outcomes in domains using a theoretical framework and identifying the COSs; (v) identification of valid measurement systems to capture the different domains and (vi) final consensus and formal approval involving experts and patients. The methods were modified from the best practice approach following the Outcome Measures in Rheumatoid Arthritis Clinical Trial and COMET manuals. RESULTS: The systematic reviews and patient focus groups identified 754 (665 + 89, respectively) relevant outcome measures. After elimination of redundancies and duplicates, 111 were formally assessed in the Delphi project. By applying pre-specified filters, the Delphi process identified 22 essential outcomes. These were reduced to 13 after aggregating alternative assessments of the same features. The expert committee organized them into four core outcome areas: (i) pathophysiology, (ii) implant/prosthesis lifespan, (iii) life impact and (iv) access to care. In each area, core outcomes were identified to capture both the benefits and harms of therapy. Mandatory outcome domains included assessment of surgical morbidity and complications, peri-implant tissue health status, intervention-related adverse events, complication-free survival and overall patient satisfaction and comfort. Outcomes deemed mandatory in specific circumstances comprised function (mastication, speech, aesthetics and denture retention), quality of life, effort for treatment and maintenance and cost effectiveness. Specialized COSs were identified for bone and soft-tissue augmentation procedures. The validity of measurement instruments ranged from international consensus (peri-implant tissue health status) to early identification of important outcomes (patient-reported outcomes identified by the focus groups). CONCLUSIONS: The ID-COSM initiative reached a consensus on a core set of mandatory outcomes for clinical trials in implant dentistry and/or soft tissue/bone augmentation. Adoption in future protocols and reporting on the respective domain areas by currently ongoing trials will contribute to improving evidence-informed implant dentistry and quality of care.

Prevention and management of peri-implant mucositis and peri-implantitis: A systematic review of outcome measures used in clinical studies in the last 10 years.

CONCLUSIONS: PPD and BOP were routinely reported in studies on the prevention and management of peri-implant mucositis and peri-implantitis, while composite outcomes, adverse events, and patient-reported outcomes were only infrequently described.

Scientific rationale for study: In 2012, recommendations on study design, key outcome measures, and reporting in clinical studies on the prevention and management of peri-implant diseases were presented. We aimed to evaluate how these recommendations were adapted and utilized in relevant studies published during the last decade. Principal findings: Recommendations on outcome measures and reporting in clinical studies on the prevention and management of peri-implant mucositis and peri-implantitis were only partially followed. Practical implications: When evaluating the evidence on the prevention and management of peri-implant diseases, the clinician should be aware of the limitations in terms of choice of outcome measures and data reporting.

Relevant domains, core outcome sets and measurements for implant dentistry clinical trials: The Implant Dentistry Core Outcome Set and Measurement (ID-COSM) international consensus report.

MRONJ in breast cancer patients under bone modifying agents for cancer treatment-induced bone loss (CTIBL): a multi-hospital-based case series.

BACKGROUND: Cancer treatment-induced bone loss (CTIBL) is the most common adverse event experienced by patients affected by breast cancer (BC) patients, without bone metastases. Bone modifying agents (BMAs) therapy is prescribed for the prevention of CTIBL, but it exposes patients to the risk of MRONJ. METHODS: This multicentre hospital-based retrospective study included consecutive non-metastatic BC patients affected by MRONJ related to exposure to low-dose BMAs for CTIBL prevention. Patients' data were retrospectively collected from the clinical charts of seven recruiting Italian centres. RESULTS: MRONJ lesions were found in fifteen females (mean age 67.5 years), mainly in the mandible (73.3%). The mean duration of BMAs therapy at MRONJ presentation was 34.9 months. The more frequent BMAs was denosumab (53.3%). Ten patients (66.7%) showed the following local risk factors associated to MRONJ development: periodontal disease (PD) in three cases (20%) and the remaining six (40%) have undergone PD-related tooth extractions. One patient presented an implant presence-triggered MRONJ (6.7%). In five patients (33.3%) no local risk factors were observed. CONCLUSIONS: This is the first case series that investigated BC patients under BMAs for CTIBL prevention suffering from MRONJ. These patients seem to have similar probabilities of developing MRONJ as osteo-metabolic ones. Breast cancer patients under BMAs for CTIBL prevention need a regular prevention program for MRONJ, since they may develop bone metastases and be treated with higher doses of BMAs, potentially leading to a high-risk of MRONJ.

Impact of rehabilitation versus edentulism on systemic health and quality of life in patients affected by periodontitis: A systematic review and meta-analysis.

AIM: To investigate the effect of rehabilitation in fully/partially edentulous patients with stage IV periodontitis on oral-health-related quality of life (OHRQoL) and systemic health. MATERIALS AND METHODS: A systematic electronic and manual search was conducted. Three authors independently reviewed, selected, and extracted the data. Outcomes were OHRQoL (Oral Health Impact Profile 14 [OHIP-14] and OHIP-49, General Oral Health Assessment Index [GOHAI], visual analogue scale, symptoms registration) and systemic health-related outcomes (incidence and prevalence of systemic diseases, values of systemic disease indicators). Qualitative data were synthesized for OHRQoL and systemic health-related outcomes. Meta-analysis was conducted on available quantitative data. RESULTS: The search identified 59 articles (6724 subjects in total). OHRQoL improved across all the studies, irrespective of the number of missing teeth, their location, or treatment modality. Meta-analysis showed significant improvement of OHIP-49 (36.86, p < .01) in manuscripts including subjects affected by periodontitis, consistently with the remaining literature (reduction of score points post rehabilitation: OHIP-14 = 10.52, OHIP-49 = 56.02, GOHAI = 5.40, p < .01 for all). Non-rehabilitated subjects exhibited inferior cognitive status, higher medication intake, and frailty. However, our data are limited and should be interpreted with caution. CONCLUSIONS: Oral rehabilitation improves OHRQoL and, potentially, systemic health in edentulous patients. It is unclear whether these findings may be extrapolated to patients with stage IV periodontitis.

Treatment of gingivitis is associated with reduction of systemic inflammation and improvement of oral health-related quality of life: A randomized clinical trial.

AIM: To compare the level of inflammatory markers, oral health-related quality of life (OHRQoL), and gingival parameters 1 month after introduction of electric toothbrush and intensive oral hygiene manoeuvre adaptation (OHI) versus routine habits (no-OHI) in patients affected by generalized gingivitis. MATERIALS AND METHODS: One hundred forty subjects with generalized gingivitis were randomized to receive either OHI or no-OHI. Full-mouth plaque/bleeding scores (FMPS/FMBS), serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and an oral health impact profile-14 questionnaire were collected at baseline and at 1-month follow-up visit. RESULTS: In the OHI, a significant FMPS and FMBS reduction (p < .01), a significant intra-group decrease in hs-CRP and IL-6 (p < .01), and a significant improvement of OHRQoL (p < .01) were noted at 1-month follow-up visit. In the no-OHI, lower-magnitude differences were noted only for oral parameters. Resolution of gingivitis varied between OHI and no-OHI (89% vs. 7%, respectively, p < .01). A logistic multivariate regression suggested that FMBS ≤8% was associated with the odds ratio of 13, having both CRP and IL-6 below the selected threshold for healthy young adults (p = .04). CONCLUSIONS: Gingivitis resolution determined important reductions of gingival inflammation and plaque levels, as well as systemic inflammatory markers and an improvement of quality of life (NCT03848351).

Periodontitis in Italian patients with established rheumatoid arthritis: A cross-sectional study.

OBJECTIVE: To assess the prevalence and severity of periodontitis (P) among Italian patients affected by rheumatoid arthritis (RA). MATERIALS AND METHODS: A full-mouth periodontal examination and a rheumatologic examination were performed. RA disease activity was scored using the DAS28. Serum analyses investigated levels of rheumatoid factor, anti-citrullinated protein antibodies (ACPAs), C-reactive protein, erythrocyte sedimentation rate and fibrinogen. Information concerning smoking, body mass index and RA medical therapy was collected. Data were analysed by Student's t test, chi-square test, binary logistic regression and Spearman's rank. RESULTS: This cross-sectional study included 120 subjects, 77 had both diseases while 43 only had RA. The number of teeth present was statistically lower in the RA-P compared to the RA group (p < .05). There were statistically more subjects seropositive for ACPAs in the RA-P group (62.3% vs. 32.6%, p < .05). RA-P patients had an adjusted OR = 2.9 of presenting a moderate-severe DAS28 score (DAS28 ≥ 3.2). CONCLUSIONS: Higher prevalence of severe P was noted among RA subjects. The clinical severity of RA was strongly correlated with the clinical periodontal parameters, and RA subjects also affected by P had an OR of 2.9 for presenting with a moderate-severe RA (DAS28 score ≥ 3.2).

Medication-Related Osteonecrosis of the Jaw Associated in a Patient Treated With Etanercept.

ABSTRACT: Medication-related osteonecrosis of the jaws (MRONJ) is defined as a pathologic condition affecting the maxillary and mandibular bones arising subsequently to pharmacological treatment with antiresorptive and antiangiogenic drugs.In this case report, the occurrence of MRONJ is described in a 66-year-old female patient affected by rheumatoid arthritis and treated with Etanercept, a Tumor Necrosis Factor (TNF)-a inhibitor. The patient developed a mandibular MRONJ following the extraction of teeth 3.4 and 3.5. The patient was then treated with conservative surgery of the necrotic bone. At 12-month follow-up complete resolution was observed. According to the data presented, the evaluation of the effects of new immunosuppressive biological therapies on the oral cavity appears of utmost importance in preventing the development of MRONJ. Although the risk related to TNF-a inhibitors has not been quantified yet, the clinician should be aware of the potential adverse effects on the oral cavity.

Oral Mucosal Melanoma.

PURPOSE: Primary oral mucosal melanoma (OMM) is a rare neoplasm accounting for the 0.2% to 0.8% of all melanomas. The aim of the present manuscript is (1) to describe 2 cases of primary OMM treated at our department, and (2) to perform a systematic literature review on primary OMM occurrence and treatment. METHODS: Two cases of primary OMM were described. A systematic review is presented in order to assess the treatment options, recurrence, metastasis development, and survival rate of primary OMM. RESULTS: Two patients were referred for the development of a lesion of the hard palate and the maxillary gingival mucosa, respectively. An incisional biopsy was performed in both patients, followed by extensive surgical resection after a thorough consideration of patient history and systemic involvement. The literature search retrieved 447 primary OMM cases. In the 30% of cases, distant metastases were already present at the time of diagnosis. The management of primary OMM most frequently involved surgical treatment and adjuvant radiotherapy. CONCLUSIONS: Primary OMM still represents a challenge for the clinician, as the diagnosis is often performed when metastases have already developed. The prognosis is generally poor, thus highlighting the need for further investigations to improve early diagnosis.

Interdental plaque reduction after the use of different devices in patients with periodontitis and interdental recession: A randomized clinical trial.

OBJECTIVES: To determine the efficacy of four different oral hygiene protocols involving adjunctive interdental devices in terms of plaque and bleeding scores in periodontitis-affected patients. MATERIAL AND METHODS: This was a randomized clinical trial with a 5-week follow-up, including previously treated periodontitis patients not undergoing any supportive care. Patients were randomly allocated to 4 groups: manual toothbrush (group TB); toothbrush plus dental floss (group TB/F); toothbrush plus interdental brushes (group TB/IDB) and toothbrush plus rubber interdental picks (group TB/RIDB). Oral hygiene instructions (OHI) were provided at baseline (T-7) and at T0 (1-week) then bi-weekly (T14/T28). At T0, supragingival professional cleaning was delivered. Plaque and bleeding indexes were taken at all timepoints by a single calibrated examiner, blind to group allocation. RESULTS: At T-7, patients were comparable for age, body mass index (BMI) and all clinical parameters, exceptions for the Interdental Angulated Bleeding Index. At T28, significant reductions of plaque and gingival inflammation were noted in all groups (p < 0.001) and within the expected ranges. Intergroup comparisons identified that group TB/IDB and group TB/RIDB achieved lower levels of plaque and inflammation than group TB (p < 0.05). Group TB/IDB and group TB/RIDB showed lower levels of plaque and lower inflammation as measured by angulated bleeding index than group TB/RIDB (p < 0.05). CONCLUSION: Interdental brushes and rubber interdental picks were more efficient than toothbrushing alone and toothbrushing and floss in reducing plaque and gingival inflammation measured in a periodontitis-affected population.

Autologous connective tissue graft or xenogenic collagen matrix with coronally advanced flaps for coverage of multiple adjacent gingival recession. 36-month follow-up of a randomized multicentre trial.

AIM: To report the 36-month follow-up of a trial comparing the adjunct of a xenogenic collagen matrix (CMX) or connective tissue graft (CTG) to coronally advanced flaps (CAF) for coverage of multiple adjacent recessions. MATERIAL AND METHODS: 125 subjects (61 CMX) with 307 recessions in 8 centres from the parent trial were followed-up for 36 months. Primary outcome was change in position of the gingival margin. Multilevel analysis used centre, subject and tooth as levels and baseline parameters as covariates. RESULTS: No differences were observed between the randomized and the follow-up population. Average baseline recession was 2.6 ± 1.0 mm. 3-year root coverage was 1.5 ± 1.5 mm for CMX and 2.0 ± 1.0 mm for CTG (difference of 0.32 mm, 95% CI from -0.02 to 0.65 mm). The upper limit of the confidence interval was over the non-inferiority margin of 0.25 mm. No treatment differences in position of the gingival margin were observed between 6- and 36-month follow-up (difference 0.06 mm, 95% CI -0.17 to 0.29 mm). CONCLUSION: CMX was not non-inferior with respect to CTG in multiple adjacent recessions. No differences in stability of root coverage were observed between groups and in changes from 6 to 36 months. Previously reported shorter time to recovery, lower morbidity and more natural appearance of tissue texture and contour observed for CMX in this trial are also relevant in clinical decision-making.
