Gingival hypersensitivity reactions to toothpastes: A case series and scoping review.

BACKGROUND: Hypersensitivity reactions to toothpastes are rare. The objective of this study was to present the authors' clinical cases in the past 10 years and perform a scoping review of gingival hypersensitivity responses to toothpastes. TYPES OF STUDIES REVIEWED: The authors reviewed records of documented gingival hypersensitivity reactions to dentifrices at the Postgraduate Clinic of Oral Medicine, Complutense University, Madrid, Spain, from January 2013 through December 2022. Furthermore, the authors conducted a search in PubMed with no date limit for articles reporting these hypersensitivity responses up through October 18, 2023. RESULTS: Eleven cases were collected from the clinic. Eight gingival hypersensitivity reactions occurred in women, and 6 were associated with cinnamon. The most frequent lesions diagnosed were red gingiva. The discontinuation of the toothpaste led to the disappearance of the lesions. The search yielded 643 references. Thirteen articles were included in the scoping review, all of them case series and case reports, reporting 32 cases. Lesions affected middle-aged women most frequently, the most common hypersensitivity reaction was gingival redness, and the cases implicated toothpastes containing cinnamon and herbal composition. PRACTICAL IMPLICATIONS: This study provides clues for diagnosing and treating hypersensitivity reactions to toothpastes, which may improve the identification, management, and reporting of these cases.

Factors influencing xerostomia and oral health-related quality of life in polymedicated patients.

OBJECTIVES: To evaluate whether the severity of xerostomia in older polymedicated patients impacts oral health-related quality of life (OHRQoL). BACKGROUND: Medication-associated xerostomia is common in older people. Xerostomia may impair OHRQoL. MATERIALS AND METHODS: This cross-sectional study included older hypertensive patients from two health centres. We assessed the severity of xerostomia and OHRQoL using the Xerostomia Inventory (XI) tool, and the Oral Health Impact Profile-14 (OHIP-14) instrument, respectively. We measured unstimulated (UWS) and stimulated (SWS) salivary flows. Univariate and multiple linear regression analyses evaluated the associations of XI and OHIP-14 and different explanatory variables. RESULTS: Of the 218 patients enrolled, 51.8% had xerostomia, and 38.1% and 27.5% suffered from UWS and SWS hyposalivation, respectively. Patients with xerostomia, UWS, and SWS hyposalivation scored significantly higher on the XI. However, only those with xerostomia or UWS hyposalivation had significantly higher OHIP-14 scores. A moderate correlation was observed between XI and OHIP-14 scores. The multiple regression model showed that factors with the greatest impact on XI were the patient's complaint of xerostomia, UWS flow rate, age and sex. However, only the XI score was significantly associated with the OHIP-14 score. CONCLUSION: Xerostomia has a negative impact on OHRQoL in older polymedicated patients, but this impact is less than in other types of xerostomia. Longitudinal studies are needed to determine whether changes in the detected explanatory variables influence XI and OHIP scores in these patients.

Effect of the use of platelet concentrates on new bone formation in alveolar ridge preservation: a systematic review, meta-analysis, and trial sequential analysis.

OBJECTIVES: To investigate the histomorphometric changes occurring in alveolar ridge preservation (ARP) based on the use of different plasma concentrates (PCs) in randomized clinical trials (RCT). There is controversy whether the placement of PCs in ARP is effective in the formation of new bone. MATERIALS AND METHODS: A systematic review search was conducted in PubMed, Scopus, Web of Science, and Cochrane Database to answer the PICO question: In patients undergoing tooth extraction followed by ARP, do PCs alone in the post-extraction socket in comparison with spontaneous healing improve new vital bone formation percentage in histomorphometric analysis after more than 10 weeks? The risk of bias was assessed and a meta-analysis was conducted. RESULTS: Of 3809 results, 8 studies were considered suitable for inclusion. A total of 255 teeth were extracted in 250 patients. Regarding the PCs used, ARP was performed with platelet- and leukocyte-rich fibrin (L-PRF) in 120 sockets, and with pure platelet-rich plasma (P-PRP) in 31 sockets and 104 sockets were controlled. PCs improved new bone formation in ARP with respect to the spontaneous healing group (SMD = 1.77, 95%C.I. = 1.47-2.06, p-value < 000.1). There were no differences between the different PCs (L-PRF and P-PRP). CONCLUSION: The results of this meta-analysis support the efficacy of the use of PCs in new bone formation in ARP. With respect to the different types of PCs studied, no differences were observed. CLINICAL RELEVANCE: When planning implant surgery after tooth extraction, treatment with PCs should be considered for ARP. Any PC increases new bone formation compared to spontaneous healing.

World Workshop on Oral Medicine VIII: Development of a core outcome set for oral lichen planus: a consensus study.

OBJECTIVE: A core outcome set (COS) is the minimum agreed-on data set required to be measured in interventional trials. To date, there is no COS for oral lichen planus (OLP). This study describes the final consensus project that brought together the results of the previous stages of the project to develop the COS for OLP. STUDY DESIGN: The consensus process followed the Core Outcome Measures in Effectiveness Trials guidelines and involved the agreement of relevant stakeholders, including patients with OLP. Delphi-style clicker sessions were conducted at the World Workshop on Oral Medicine VIII and the 2022 American Academy of Oral Medicine Annual Conference. Attendees were asked to rate the importance of 15 outcome domains previously identified from a systematic review of interventional studies of OLP and a qualitative study of OLP patients. In a subsequent step, a group of OLP patients rated the domains. A further round of interactive consensus led to the final COS. RESULTS: The consensus processes led to a COS of 11 outcome domains to be measured in future trials on OLP. CONCLUSION: The COS developed by consensus will help reduce the heterogeneity of outcomes measured in interventional trials. This will allow future pooling of outcomes and data for meta-analyses. This project showed the effectiveness of a methodology that could be used for future COS development.

World Workshop on Oral Medicine VIII: Development of a core outcome set for oral lichen planus: the patient perspective.

OBJECTIVE: This study aimed to explore the lived experience of patients with oral lichen planus (OLP) and investigate what treatment-related outcomes are the most important to them and should be included in a core outcome set (COS) for OLP. STUDY DESIGN: A qualitative study involving focus group work with 10 participants was conducted. Interviews with each focus group were held twice: session 1 explored the lived experience of patients with OLP, and session 2 allowed patients to review a summary of the outcome domains used in the OLP literature to date. The discussions were recorded, transcribed verbatim, and analyzed using framework analysis. RESULTS: In session 1, 4 themes and 8 sub-themes emerged from the data analysis. An additional outcome, 'knowledge of family and friends,' was suggested in session 2. CONCLUSIONS: We have gained valuable insight into the lived experience of patients with OLP via this qualitative study. To our knowledge, this study is the first to explore the patient perspective on what should be measured in clinical trials on OLP, highlighting an important additional suggested outcome. This additional outcome will be voted upon in a consensus process to determine a minimum COS for OLP.

World Workshop on Oral Medicine VIII: Development of a core outcome set for oral lichen planus: a systematic review of outcome domains.

OBJECTIVE: There is a lack of consensus regarding clinician- and patient-reported oral lichen planus (OLP) outcomes. The World Workshop on Oral Medicine Outcomes Initiative for the Direction of Research (WONDER) Project aims to develop a core outcome set (COS) for OLP, which would inform the design of clinical trials and, importantly, facilitate meta-analysis, leading to the establishment of more robust evidence for the management of this condition and hence improved patient care. STUDY DESIGN: Ovid MEDLINE, Embase, CINAHL, CENTRAL, and Clinicaltrials.gov were searched for interventional studies (randomized controlled trials, controlled clinical trials, and case series including ≥5 participants) on OLP and oral lichenoid reactions published between January 2001 and March 2022 without language restriction. All reported primary and secondary outcomes were extracted. RESULTS: The searches yielded 9,135 records, and 291 studies were included after applying the inclusion criteria. A total of 422 outcomes were identified. These were then grouped based on semantic similarity, condensing the list to 69 outcomes. The most frequently measured outcomes were pain (51.9%), clinical grading of the lesions (29.6%), lesion size/extension/area (27.5%), and adverse events (17.5%). CONCLUSION: As a first step in developing a COS for OLP, we summarized the outcomes that have been used in interventional studies over the past 2 decades, which are numerous and heterogeneous.

Efficacy and safety of a bioadhesive gel containing propolis extract, nanovitamin C and nanovitamin E on desquamative gingivitis: a double-blind, randomized, clinical trial.

OBJECTIVES: To evaluate the efficacy of a gel-containing propolis extract, nanovitamin C, and nanovitamin E as adjuvants to professional plaque removal on desquamative gingivitis (DG). MATERIALS AND METHODS: A randomized clinical trial was conducted on patients suffering DG due to mucocutaneous diseases. Patients received professional supragingival prophylaxis with oral hygiene instructions and were randomly assigned to use test or control gels as toothpaste and to apply it on DG lesions 3 times/day for 4 weeks. DG clinical score (DGCS), clinical periodontal variables, and visual analog scale (VAS) for pain and oral health impact profile (OHIP-14) were collected at baseline, 2 and 4 weeks. RESULTS: Twenty-two patients were randomly assigned to test (n = 11) or control group (n = 11). Eighteen had diagnosis of oral lichen planus and four of mucous membrane pemphigoid. DGCS statistically decreased in both groups after treatment with no significant differences between groups. Clinical periodontal outcomes decreased in both groups, but no significant differences were observed. Periodontal variables statistically improved only in test group after treatment. VAS and OHIP-14 scores decreased in test and control groups without significant differences. However, only one test group showed a statistically significant decrease in VAS and OHIP-14 scores after treatment. No adverse effects were reported. CONCLUSIONS: Test gel may alleviate DG and improve quality of life without side effects. CLINICAL RELEVANCE: A gel-containing propolis extract, nanovitamin C, and nanovitamin E as adjuvants to mechanical debridement may improve both clinical and patient related outcomes in DG patients without side effects. CLINICAL TRIAL REGISTRATION: The study protocol was registered at clinicaltrials.gov with the following number: NCT05124366 on October 16, 2021.

Risk factors associated with xerostomia and reduced salivary flow in hypertensive patients.

OBJECTIVE: The aim of this study was to evaluate the risk factors associated with xerostomia and hyposalivation in a group of hypertensive patients. SUBJECTS AND METHODS: A cross-sectional study was conducted. Hypertensive patients belonged to two healthcare centers were included. Xerostomia was assessed by asking a question and using the Xerostomia Inventory. Unstimulated salivary flow was collected. Different epidemiological variables were analyzed such as age, sex, habits, diseases, drugs, and blood pressure. RESULTS: 221 individuals were included. Xerostomia was reported in 51.13% of patients. Patients with xerostomia suffered more from osteoarthritis and diaphragmatic hernia. These patients took more anticoagulants (acenocoumarol), antiarrhythmics (amiodarone), analgesics (paracetamol) and epilepsy drugs (pregabalin) and less platelet aggregation inhibitors and angiotensin II receptor blockers (losartan). Unstimulated flow was reduced in 37.56% of patients. Patients suffering hyposalivation presented more diseases such as anxiety, infectious or parasitic diseases, hepatitis C, diaphragmatic hernia, and osteoarthritis. These patients took more repaglinide, thiazides, anti-inflammatories, anti-rheumatics, glucosamine, diazepam, and selective beta-2-adrenoreceptor agonists and less combinations of candesartan and diuretics. CONCLUSIONS: Xerostomia and hyposalivation are frequent in hypertensive patients. It is advisable to take into consideration the comorbidities and the drugs they receive, since they can increase the risk of these salivary disorders.

Oral health status and dental care for individuals with visual impairment. A narrative review.

Visual impairment is a highly prevalent condition worldwide. Oral health care in this group of patients is not always adequate. This is due to the low awareness of the importance of oral health in this population group and the fact that these patients prioritize their general health over oral health. Therefore, caries and periodontal disease are frequent in this population group. Especially, periodontal status is worse in patients with acquired visual impairment compared to patients with congenital visual impairment. On the other hand, the proportion of treated caries in this group is very low. This may be due to the poorer access of this population to dental care, which is limited by physical, social, and information barriers. Dental phobia and the lack of dental professionals capable of treating this population group have been identified as one of the most important factors. Therefore, establishing oral hygiene routines that are adapted to individuals' skills and needs is essential to achieve good oral health and improve patient's quality of life. This narrative review also updates those dental treatment considerations, depending on each dental specialty, that can help improve patient satisfaction when they come to the dental office.

Salivary biomarkers in burning mouth syndrome: A systematic review and meta-analysis.

The objective of this systematic review was to evaluate which salivary biomarkers are altered in patients with burning mouth syndrome (BMS) compared to a control group (CG). A comprehensive literature search was conducted in four databases. Case-control studies evaluating salivary biomarkers in BMS patients were included. Risk of bias was assessed using the Newcastle-Ottawa tool. RevMan was used for meta-analysis. Seventeen studies were selected. The included studies collected 54 different biomarkers. Of these biomarkers, only three (cortisol, α-amylase, and dehydroepiandrosterone) were analyzed in three or more studies. Dehydroepiandrosterone obtained contradictory results among the studies. However, cortisol and α-amylase levels were found to be higher in BMS patients. Cortisol was the only biomarker which could be included for meta-analysis. Cortisol levels were significantly higher in the BMS group compared to the CG (Mean Difference = 0.39; 95% CI [0.14-0.65]; p = 0.003). In conclusion, different studies investigated salivary biomarkers in patients with BMS compared to a CG, with controversial results. Meta-analysis, confirmed by trial-sequential analysis, showed how cortisol levels were significantly higher in BMS. Cortisol emerges as an interesting salivary biomarker in BMS, but future properly designed studies are needed to evaluate its role in diagnosis and/or response to treatment.

Usefulness of implementing the OHIP-14 questionnaire to assess the impact of xerostomia and hyposalivation on quality of life in patients with primary Sjögren's syndrome.

BACKGROUND: The aim of this study is to analyze if the results of the Oral Health Impact Profile-14 questionnaire (OHIP-14) in patients with primary Sjögren's syndrome (pSS) are correlated with salivary flow and level of xerostomia. METHODS: This observational cross-sectional study was conducted in 61 patients (60 women, one man, mean age 57.64 [13.52]) diagnosed of pSS according to the American-European Criteria (2002). After recording demographic, medical and dental data (decayed-missing-filled teeth index [DMFT]), unstimulated (UWS) and stimulated (SWS) salivary flows were collected. Subsequently, UWS flow was categorized into two groups (<0.1 ml/min and ≥0.1 ml/min) and SWS into three groups (<0.1 ml/min, 0.1-0.7 ml/min and >0.7 ml/min). Patients also filled out a visual analog scale (VAS) for xerostomia and OHIP-14 for self-reported quality of life (QoL). RESULTS: Data showed positive and significant correlation between OHIP-14 and xerostomia, based on VAS results (r = 0.52; p = 0.001). Furthermore, there was a negative correlation between UWS and OHIP-14 scores (r = -0.34; p = 0.006) and VAS for xerostomia (r = -0.22; p = 0.09). No significant correlation was found between SWS and OHIP-14 or VAS neither between DMFT and OHIP-14. When assessing the level of QoL by the UWS and SWS flow categories a significant association was found for UWS (p = 0.001) but not for SWS (p = 0.11). The OHIP-14 values were higher in the groups with lower salivary flow. The multiple linear regression to predict OHIP-14 only selected VAS for xerostomia as a statistically significant predictor. CONCLUSIONS: Increased level of xerostomia and reduced UWS flow decrease oral health-related QoL in patients with pSS.

Periosteal Pocket Flap technique for lateral ridge augmentation. A comparative pilot study versus guide bone regeneration.

BACKGROUND: Implant rehabilitation of posterior mandibular defects is frequently associated to a horizontal bone loss. There exist several regenerative techniques to supply this bone deficiency, one of which is the Periosteal Pocket Flap Technique (PPF) proposed by Steigmann et al. to treat small horizontal bone defects. The present study proposes a modification of this technique based on the concurrent use of PPF with the use of xenogeneic and autologous bone and Plasma Rich in Growth Factors (PRGF). The aim of this study is to evaluate clinical and radiographic outcomes of the PPF with the use of xenogeneic and autologous bone and PRGF in comparison with conventional Guided Bone Regeneration (GBR) procedures. METHODS: Nine patients were enroled in the study (7 women and 2 men, mean age: 53 ± 2.74 years) and allocated to PPF or GBR. In both groups implant placement was performed simultaneously to bone regeneration. Preoperative CBCT scans were performed for each patient. Surgical time and postoperative pain were recorded, as well as tissue healing. Moreover, horizontal bone gain (mm), graft surface area (mm2) and graft volume (mm3) were evaluated. RESULTS: Nine surgeries were performed: 6 PPF and 3 GBR. Regarding clinical outcomes, operative time was significative greater in GBR group than in PPF group (51.67 ± 3.51 min vs. 37 ± 5.69 min; p = 0.008). Postoperative pain was higher in GBR compared to PPF (p = 0.011). Regarding radiographical results, there were not significant differences in horizontal bone gain (PPF: 9.43 ± 1.8 mm; GBR: 9.28 ± 0.42 mm), surface area (PPF: 693.33 ± 118.73 mm2; GBR: 655.61 ± 102.43 mm2), and volume (PPF: 394.97 ± 178.72 mm3; GBR: 261.66 ± 118 mm3) between groups. CONCLUSIONS: This prospective study demonstrates that the combination of autograft/xenograft and PRGF in PPF technique is a simpler, cheaper, and faster technique than GBR technique for achieving moderate lateral bone augmentation in implant treatment. Future randomised clinical studies are needed to confirm the results.

Salivary LDH in oral cancer and potentially malignant disorders: A systematic review and meta-analysis.

OBJECTIVES: To evaluate whether salivary lactate dehydrogenase (LDH) levels are increased in patients with oral cancer (OC) or oral potentially malignant disorders (OPMD) when compared to a healthy control group (CG). MATERIAL AND METHODS: We conducted a comprehensive search of specialized databases (PubMed/MEDLINE, The Cochrane Library, Web of Science, Scopus, and OpenGrey), including observational analytical studies evaluating the salivary LDH levels (in UI/L or µ/L) in OC or OPMD patients and compared them with a CG. RESULTS: Thirteen case-control studies were included. A total of 755 patients were evaluated, including 303 OC cases, 149 OPMD cases, and 303 controls. The meta-analysis showed that LDH levels were higher within the OC group than the CG (SMD 9.49; 95% CI 6.97-12; p = .00001). Patients with oral leucoplakia (SMD 11.67; 95% CI 1.01-22.33; p = .03) and oral submucous fibrosis (SMD 25.83; 95% CI -1.74-53.40; p = .07) also presented higher levels than the CG. In addition, OC patients had higher salivary LDH levels than oral leucoplakia patients (SMD 5.62; 95% CI 2.14-9.11; p = .002). Heterogeneity was high across all the evaluated studies. CONCLUSIONS: The determination of salivary LDH may be a useful method for screening and tracking OC and OPMD, but new protocolized studies are required to establish precise cutoff values.

Effect of Platelet Concentrates on Marginal Bone Loss of Immediate Implant Procedures: A Systematic Review and Meta-Analysis.

BACKGROUND: To evaluate marginal bone loss (MBL) in immediate implant procedures (IIP) placed in conjunction with platelet concentrates (PCs) compared to IIP without PCs. METHODS: A search was performed in four databases. Clinical trials evaluating MBL of IIP placed with and without PCs were included. The random effects model was conducted for meta-analysis. RESULTS: Eight clinical trials that evaluated MBL in millimeters were included. A total of 148 patients and 232 immediate implants were evaluated. The meta-analysis showed a statistically significant reduction on MBL of IIP placed with PCs when compared to the non-PCs group at 6 months (p < 0.00001) and 12 months (p < 0.00001) follow-ups. No statistically significant differences were observed on MBL of IIP when compared PCs + bone graft group vs. only bone grafting at 6 months (p = 0.51), and a significant higher MBL of IIP placed with PCs + bone graft when compared to only bone grafting at 12 months was found (p = 0.03). CONCLUSIONS: MBL of IIP at 6 and 12 months follow-ups is lower when PCs are applied in comparison to not placing PCs, which may lead to more predictable implant treatments in the medium term. However, MBL seems not to diminish when PCs + bone graft are applied when compared to only bone grafting.

Socket shield technique: A systematic review of human studies.

BACKGROUND AND PURPOSE: Alveolar bone resorption after dental extraction frequently leads to situations in which long-term function and esthetic success of rehabilitations with dental implants is a challenge. Socket shield has been described as an alternative technique to maintain the alveolar ridge when placing immediate implants. The aim of this review is to evaluate the medium- and long-term clinical outcomes of the socket shield technique in human studies. MATERIAL AND METHODS: This review was conducted according to PRISMA guidelines. An electronic search was conducted in four databases: (1) The National Library of Medicine (MEDLINE/PubMed) via Ovid; (2) Web of Science (WOS); (3) SCOPUS; and (4) Cochrane Central Register of Controlled Trials (CENTRAL). The Cochrane Collaboration tool, the Newcastle-Ottawa Quality Assessment Scale and The Joanna Briggs Institute Critical Appraisal tool were used to assess the quality of evidence in the studies reviewed. RESULTS: Six articles were included in this review. The studies analysed showed lower rates of horizontal and vertical alveolar bone resorption, better maintenance of the buccal plate, less marginal bone loss and better esthetic results than simple placement of immediate implants. However, a lack of homogeneity was found in evaluation methods of the different outcomes, surgical procedures and prosthetic management. CONCLUSIONS: Based on the results of this review, it is possible to suggest that socket shield technique could be a good alternative in terms of alveolar bone maintenance, marginal bone stability and aesthetic outcomes in immediate implant treatment. However, it is not possible to recommend this technique as an alternative treatment with the same long-terms predictability as conventional immediate implants.

Split bone block technique: 4-month results of a randomised clinical trial comparing clinical and radiographic outcomes between autogenous and xenogeneic cortical plates.

PURPOSE: To evaluate short-term clinical and radiographic outcomes of bone regeneration procedures using thin cortical porcine xenogeneic bone plates in combination with autogenous bone chips compared with thin autogenous cortical plates and autogenous bone chips. MATERIALS AND METHODS: A total of 19 patients (12 women and 7 men, mean age 58.24 ± 3.09 years) were randomly allocated to two different groups regarding surgical procedure: autogenous cortical plates (ACP group) and xenogeneic cortical plates (XCP group). Preoperative CBCT scans were performed for each patient. Surgical time and postoperative pain were recorded, as well as tissue healing and graft resorption after 4 months, then another surgical procedure was performed to place dental implants. Data were analysed using an analysis of covariance. RESULTS: Twenty-one surgical procedures were performed on 19 patients (10 from the XCP group and 9 from the ACP group). The operative time was significantly lower in the XCP group (25.45 ± 3.88 minutes) than in the ACP group (44.10 ± 3.60 minutes). The XCP group also showed less pain, but not significantly less, than the ACP group. The graft resorption rate in the ACP and XCP groups was 2.03 ± 1.58% and 3.49 ± 2.38% respectively, showing no statistically significant difference. CONCLUSIONS: Despite the limited sample size and non-uniform distribution between the maxilla and mandible as surgical sites, the results suggest that XCP and ACP grafts are similar in terms of bone volume gain and graft resorption rate, with no significant differences in wound healing or complication rate. Nevertheless, the XCP group recorded lower pain levels and required significantly less operative time compared to the ACP group.

Genes involved in the epithelial-mesenchymal transition in oral cancer: A systematic review.

OBJECTIVE: Epithelial-mesenchymal transition (EMT) is considered the initial step in the invasion-metastasis cascade. The aim of this systematic review was to study the signature of genes involved in the EMT process in oral cancer (OC) confirmed by protein expression and its possible relationship with oral squamous cell carcinoma (OSCC) prognostic variables. MATERIALS AND METHODS: A search of the scientific literature was carried out with no start date restriction until 17 September 2020 in the electronic databases Pubmed/MEDLINE, Web of Science, Cochrane Library and Scopus, following specific eligibility criteria. The methodological quality of the included studies was assessed using the Newcastle-Ottawa tool. RESULTS: A total of 8 retrospective cohort studies were included, all of them performed in China and with low risk of bias. Overexpression of the genes HNRNPC, ITGA5, HMGA2 and SRSF3, and low expression of ALDH3A1 and ARID2 promote EMT in OC. The more advanced clinical stages of the TNM classification were significantly associated with overexpression of HNRNPC, ITGA5, HMGA2 and SRSF3, and low expression of ARID2. CONCLUSIONS: HNRNPC, ITGA5, HMGA2, SRSF3, ALDH3A1 and ARID2 genes were associated with EMT process. Over- or under-expression of these genes is associated with worse stages of OSCC and/or worse prognosis of the tumor. Further studies on this topic are needed in different countries to be able to confirm these results, since the detection of these genes can help to know which tumors have a worse prognosis.

Short-term efficacy of a gel containing propolis extract, nanovitamin C and nanovitamin E on peri-implant mucositis: A double-blind, randomized, clinical trial.

OBJECTIVE: To determine the efficacy of a gel containing propolis extract, nanovitamin C and nanovitamin E as adjuvant to mechanical debridement in the treatment of peri-implant mucositis (PM). BACKGROUND: Propolis has anti-inflammatory and antibacterial effect that may improve peri-implant health. METHODS: A randomized, double-blind study was performed on patients with at least one implant with PM. Participants received a professional prophylaxis and were instructed to use either test or a control gel as toothpaste three times/day for 1 month. Clinical and microbiological parameters were evaluated. PM resolution was considered in absence of bleeding on probing (BOP). Data were analysed with Mann-Whitney U, Wilcoxon signed-rank and chi-square tests. RESULTS: Forty-six patients participated (23 in each group). After treatment, 26.1% of test patients showed complete PM resolution versus 0% in control group (p = .02). Significant reductions were observed in plaque index (p = .03), BOP (p = .04) and probing depths (p = .027) in test compared with control group. The reduction in Tannerella forsythia was statistically greater in test than in control group at 1-month follow-up (p = .02). Porphyromonas gingivalis was statistically reduced in test group from baseline to 1-month follow-up (p = .05). CONCLUSION: Test gel clinically improved PM and showed certain antimicrobial effect after 1 month in comparison with control group. Further long-term clinical trials are required to confirm these results.

Application of propolis extract, nanovitamin C and nanovitamin E to prevent alveolar osteitis after impacted lower third molar surgery. A randomized, double-blind, split-mouth, pilot study / Aplicación de extracto de propóleo, nanovitamina C y nanovitamina E para prevenir la osteítis alveolar después de una cirugía de terceros molares inferiores retenidos. Un estudio piloto aleatorizado, doble ciego y de boca dividida

Background: Propolis has anti-inflammatory, analgesic and healing properties. The purpose of this study was todetermine whether a gel containing 2% of propolis extract, 0.2% of ascorbic acid and 0.2% of tocopherol acetateis effective in preventing surgical complications related to impacted lower third molar extractions.Material and Methods: A randomized, double-blind, split-mouth study was performed. Fifteen patients were re-cruited who needed bilateral impacted lower third molar extractions with a similar surgical difficulty. A test orplacebo gel was administered randomly inside post-extraction sockets. Each patient was instructed to apply thegel 3 times/day in the surgical wound for a week. After a month, the contralateral third molar was extracted, andthe opposite gel applied. The following parameters were diagnosed/evaluated and then recorded: alveolar osteitisfollowing Blum’s criteria, swelling and trismus at day one, two, three and seven post-intervention, wound healingat day 7 post-intervention, and postoperative pain using a visual analog scale, as well as, the number of analgesicpill intake.Results: A total of twenty-six surgical procedures were performed in 13 patients (mean age 20.67±2 years). Alveo-lar osteitis was reported in 3 patients from the placebo group (23.1%) and none in the test group (0%) (p=0.25). Nostatistically significant differences were reported in swelling, trismus, wound healing or analgesic pill consump-tion between two groups. But statistically lower postoperative pain during the 7 days after surgical extractionswas found according to visual analog scale in test group compared to the placebo group (p=0.007). No side effectswere reported.(AU)

Evaluación protocolizada odontológica en el paciente con síndrome de Sjögren primario. Proyecto EPOX-SSp: metodología y objetivos / Protocolised odontological assessment of patients with primary Sjögren's syndrome

Objetivo: El objetivo de este estudio es describir los hallazgos de una evaluación odontológica protocolizada en pacientes con síndrome de Sjögren primario (SSp) atendidos en las consultas de reumatología de la Comunidad de Madrid. Métodos: Estudio descriptivo multicéntrico en el que se incluyeron pacientes con SSp clasificados según criterios del consenso Europeo-Americano de 2002. Se recogieron datos demográficos, clínicos y serológicos. Se realizó una exploración oral, se recogió el flujo salival y el índice de caries CAOD. Los pacientes rellenaron la escala visual analógica para xerostomía, el cuestionario Oral Health Impact Profile-14 y un cuestionario de salud oral. Resultados: Se reclutaron 61 pacientes. El 98% fueron mujeres y la edad media fue de 57 años. El 52,5% presentaban signos orales patológicos (flujo salival no estimulado/sialografía/gammagrafía de glándulas salivales) y el 90,2% antiRo/antiLa+. El 92% de los pacientes referían xerostomía y un 61% hiposialia. Treinta y cinco pacientes presentaron lesiones de la mucosa oral. El índice CAOD fue de 16,97±7,93 y la escala visual analógica para la xerostomía fue de 46,69±14,43. Los resultados del Oral Health Impact Profile-14 fueron de 23,13±14,16. Los pacientes con signos orales patológicos obtuvieron una puntuación en el Oral Health Impact Profile-14 significativamente mayor (p=0,03), al igual que los pacientes con afectación del sistema nervioso periférico (p=0,001). Conclusiones: La prevalencia de xerostomía en esta cohorte de pacientes con SSp fue muy elevada y el 61% de los enfermos presentaron hiposialia. Más de la mitad de los pacientes sufrieron lesiones orales. La salud oral presentó un impacto negativo en la calidad de vida de los pacientes con SSp, siendo mayor en aquellos pacientes con signos orales objetivos patológicos y en los que presentaban afectación del sistema nervioso periférico.(AU)

Objective: The aim of this study is to describe the findings of a protocolised odontological evaluation of patients with primary Sjögren's syndrome (pSS) treated in rheumatology units in the Community of Madrid. Methods: Multicentric descriptive study in which pSS patients classified according to the American-European consensus of 2002 criteria were included. We collected the demographic, clinical and serological data of each patient. A complete oral examination was performed and salivary flow and the CAOD caries index were collected. The patients completed the visual analogue scale for xerostomia, the Oral Health Impact Profile-14 questionnaire and an oral health questionnaire. Results: Sixty-one patients were recruited. Ninety-eight percent were women and the mean age of the patients was 57 years. Pathological oral signs (unstimulated salivary flow/salivary glands sialography/scintigraphy) were present in 52.5% of the patients, anti-Ro/anti-La were positive in 90.2%. Ninety-two percent of the patients reported xerostomia and 61% of the patients suffered from hyposialia. Thirty-five patients presented oral mucosa lesions. CAOD index was 16.97±7.93 and visual analogue scale for xerostomia was 46.69±14.43. The results of the OHIP-14 questionnaire were 23.13±14.16. Patients with pathological oral signs obtained a significantly higher Oral Health Impact Profile-14 score (P=.03). We also found that patients with peripheral nervous system involvement obtained a significantly higher Oral Health Impact Profile-14 score (P=.001) Conclusions: The presence of xerostomia in this cohort of pSS patients was high and hyposialia was present in 61% of the patients. Oral lesions appeared in more than half of the subjects. Oral health had a negative impact on the quality of life of patients with pSS, being higher in those with pathological objective oral signs and in those with peripheral nervous system involvement.(AU)
