RESUMO
Non-secretory multiple myeloma (NSMM) is a rare cancer of plasma cells characterized by the absence of detectable monoclonal M protein in the blood or urine. A 57-year-old woman presented with mandibular pain but without intraoral swelling. Imaging studies revealed multiple osteolytic lesions in her mandible and pronounced root resorption of the left mandibular second molar. Biopsy results showed atypical plasmacytoid cells positive for anti-kappa, CD138, MUM1, and CD79a antibodies, but negative for anti-lambda and CD20. These results were indicative of a malignant plasma cell neoplasm. No abnormalities were revealed by free light chain assay or by serum or urine protein electrophoresis, leading to a diagnosis of NSMM. The patient began chemotherapy in conjunction with bisphosphonate therapy and achieved remission following treatment. This case underscores the critical role of dentists in the early detection and prevention of NSMM complications, as the disease can initially present in the oral cavity.
RESUMO
BACKGROUND: This study aims primarily to assess the mandibular condyles and patient response to MAD therapy using cone-beam computed tomography (CBCT). Also, the study proposes to analyze whether variations in condylar position, OSA severity and mandibular protrusion influence patient response. METHODS: 23 patients diagnosed with mild/moderate OSA and treated with MAD comprised the sample. Clinical, CBCT, and PSG assessments were conducted at baseline and with MAD in therapeutic protrusion (4-6 months of MAD use). The condyle position was vertically and horizontally evaluated at baseline and at the therapeutic protrusion. RESULTS: The condyle position significantly changed with MAD, showing anterior (7.3 ± 2.8 mm; p < 0.001) and inferior (3.5 ± 1 mm; p < 0.001) displacement. Patients with mild OSA required more protrusion (p = 0.02) for improvement. Responders exhibited a significantly prominent (p = 0.04) anterior baseline condyle position. A negative modest correlation was found between treatment response and baseline condyle anterior position (p = 0.03; r=-0.4), as well as between OSA severity and the percentage of maximum protrusion needed for therapeutic protrusion (p = 0.02; r=-0.4). The patient protrusion amount did not predict condylar positional changes. Neither condyle position, OSA severity, nor therapeutic protrusion were predictors of MAD treatment response. CONCLUSION: MAD resulted in anterior and inferior condylar displacement, and the amount of protrusion did not predict condylar positional changes. Responders showed a more anterior baseline condyle position. OSA severity and mandibular protrusion did not predict treatment response.
RESUMO
The mandibular interforaminal region has been considered safe for surgical procedures; nevertheless, the risk of injury to neurovascular structures, such as the mental foramen (MF) and its related structures (anterior loop [AL] and lingual foramina [LF]) should not be overlooked. The study aimed to evaluate the relative risk of injury to these structures during surgical procedures in the anterior region of the mandible based on cone-beam computed tomography (CBCT) scans. A retrospective cross-sectional and observational study was performed on 250 CBCTs from adults (18-69 years) with dentate jaws. Linear measurements of the MF, AL, and LF were evaluated to estimate the risk of injury to these structures during chin-related surgical procedures. The most frequent distance between the base of the mandible (BM) and MF was 8 mm (30.2%). In addition, 20.4% of the CTs had 6 mm from the vestibular cortical bone to the LF. The commonly found measurement from LF to the apex of the nearest tooth was 7 mm (24.0%); 64.2% of the CTs showed a 2-mm distance between the most distal point of the dental implant site to the most anterior point of the AL. Safety distances for genioplasty techniques (MF to mandible base > 6 mm, 96.6% [CI 95%, 95.0%-98.2%]) were observed. Considering the 5-mm cut-off point between the lower limit of a hypothetical bone graft and the chin, 65.4% (CI 95%, 58.9%-71.9%) of CTs were within this distance. Regarding the safety margin of 8 mm, 85.6% (CI 95%, 80.8%-90.4%) were up to this value. This study found safety margins for genioplasty and chin bone grafting surgical techniques that adopt a 5-mm cut-off point. Further similar studies assessing other surgical methods and employing larger samples from different geographical origins may contribute to this field of investigation.

PURPOSE: This study aims to conduct a thorough analysis, both quantitative and qualitative, of bibliometric parameters related to preemptive analgesia (PA) in oral surgical procedures (OSP). METHODS: Research trends on PA in OSP using ibuprofen were reviewed through bibliometric analysis of 68 journal articles published from 1991 to 2022 in the Web of Science database. Bibliometric indicators were applied to analyze the journal article data, including the annual distribution of publications and literature growth, document types, citation indicators to measure qualitative research performance, and keyword mapping to identify research trends. The results were imported into RStudio, and the Bibliometrix package was used to prepare and analyze the metadata. RESULTS: The 68 included articles received a total of 900 citations, ranging from 1 source to 72 citations with some fluctuations. The papers on PA in OSP using ibuprofen had an average of 16.85 citations per paper. These publications were originated from 25 countries, with the highest contributions from Brazil (n = 17), the USA (n = 13), and Turkey (n = 8). The top five major contributing journals were the International Journal of Oral and Maxillofacial Surgery, Journal of Oral and Maxillofacial Surgery, Journal of Cranio-Maxillo-Facial Surgery, Journal of Periodontology, and Acta Odontologica Scandinavica, representing more than half of all selected papers. CONCLUSION: Papers focused on PA in OSP received numerous citations. The citation per article correlated with the number of publications at the affiliation, author, country, and journal levels. However, there is still a scarcity of studies in this field.
RESUMO
This cross-sectional study evaluated the association between salivary immunoglobulins, plaque index, and gingival index in Brazilian children with and without type 1 diabetes mellitus (DM1). The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for the reporting of observational studies was followed. The DM1 group had 38 children, and an equal number of volunteers matched by sex and age were recruited as controls. Clinical examination was performed for plaque index and gingival index determination. Non-stimulated whole saliva was collected. Concentrations of IgA, IgG, and IgM were determined by ELISA test. Data were tested by the Kolmogorov-Smirnov, Mann-Whitney, and Spearman tests and a multiple linear regression model (p<0.05) was performed. Gingival index was higher in the Control (DM1: 0.16±0.17; Control: 0.24±0.23, p=0.040). In DM1, there was a correlation between IgA and age (rho=0.371, p=0.024), IgM and IgG (rho=0.459, p=0.007), and IgM and gingival index (rho=0.394, p=0.014). In DM1, multiple linear regression showed that age (p=0.041; ß=0.363), gingival index (p=0.041; ß=0.398), and plaque index (p=0.008; ß=-0.506) were good predictors of IgA levels in saliva. Thus, IgA was the only researched immunoglobulin that was directly associated with plaque and gingival indices in Brazilian children with DM1, but not in control subjects.

Background: To evaluate the influence of chemotherapy on the prevalence of trismus in irradiated head and neck cancer patients. Material and Methods: This systematic review guided by PRISMA-2020 and registered in PROSPERO (CRD42021255377) screened 963 articles in 7 scientific-databases (PubMed, Lilacs, Livivo, Scopus, Embase, Web of Science, EBSCO) and 3 grey-literature databases (Open Grey, Google Scholar, ProQuest) and eight articles were included for qualitative synthesis, meta-analysis (combined odds ratio, inverse variance method plus random effects), heterogeneity analysis (I² and Tau²), one-of-out evaluation and publication bias analysis (Eggs' and Begg's tests) (RevMan®, p<0.05). The Newcastle-Ottawa Quality Assessment Scale Cohort Studies was used to assess the risk of bias (RoB). The classification assessment, development, and recommendations (GRADE) approach was used to assess the certainty of evidence. Results: The eight articles evaluated 1474 patients treated with chemoradiotherapy and 858 patients treated with radiotherapy. Five articles had low RoB, and three had high RoB. Chemoradiotherapy significantly (p=0.0003) increased the prevalence of trismus (OR=2.55, 95% CI = 1.53-4.23) compared to radiotherapy, with significant (p=0.010) but low heterogeneity (I²=59%;Tau²=0.29). There was no significant risk of publication bias, one-out analysis showed no significant difference between studies, and GRADE showed a moderate level of evidence. Trismus was directly associated to worse quality of life. Conclusions: The incidence of trismus increases when chemotherapy is combined with radiotherapy for head and neck cancer, which negatively impacts the quality of life. Key words:Radiotherapy, Chemoradiotherapy, Head and Neck Neoplasms, Trismus, Quality of Life.

Foi encontrada correlação positiva entre IDB com IQSP e ESE (r = 0,478; p = 0,000 e r = 0,202; p = 0,000, respectivamente). Os resultados mostraram uma alta prevalência de má qualidade de sono e SDE e ambos os achados apresentaram associação com sintomas depressivos.
Sleep is an essential state for human survival. It has a biological, restorative and energy conservation function for the organism, promoting physical and mental balance. A high prevalence of poor sleep quality and excessive daytime sleepiness (EDS) has been reported among university students from different courses, causing impaired concentration and a drop in academic performance. This study evaluates sleep quality, EDS and their possible associations with depressive symptoms in dentistry students. A cross-sectional descriptive research was conducted with 251 students from the Dentistry Course at the School of Pharmacy, Dentistry and Nursing, Federal University of Ceará. Variables of interest were assessed by Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS) and Beck Depression Inventory (BDI). Results show a high prevalence of poor sleep quality (53.4%) and EDS (35.1%) among students, with no significant difference regarding gender. BDI had a positive correlation with PSQI and ESS (r= 0.478, p= 0.000; and r= 0.202, p =0.000, respectively). Both findings were associated with depressive symptoms.

RESUMO
BACKGROUND: Anthropometric measurements can be used to identify children at risk of developing obstructive sleep apnea (OSA). The study aimed to assess which anthropometric measurements (AMs) are most associated with an increased predisposition to develop OSA in healthy children and adolescents. METHODS: We performed a systematic review (PROSPERO #CRD42022310572) that searched eight databases and gray literature. RESULTS: In eight studies with low-to-high risk of bias, investigators reported the following AMs: body mass index (BMI), neck circumference, hip circumference, waist-to-hip ratio, neck-to-waist ratio, waist circumference, waist-to-height ratio, and facial AMs. The meta-analysis showed that the OSA group had an average of 1.00 cm greater for the neck circumference (p < 0.001; Cohen's d = 2.26 [0.72, 5.23]), 3.07 cm greater for the waist circumference (p = 0.030; Cohen's d = 0.28 [0.02, 0.53]), 3.96 cm greater for the hip circumference (p = 0.040; Cohen's d = 0.28 [0.02, 0.55]), 5.21° greater for the cervicomental angle (p = 0.020; Cohen's d = 0.31 [0.03, 0.59]), and 1.23° greater for maxillary-mandibular relationship angle (p < 0.001; Cohen's d = 0.47 [0.22, 0.72]) than the control group. The mandibular depth angle had a reduction of 1.86° (p = 0.001; Cohen's d = -0.36° [-0.65, -0.08]) in control than in patients with OSA. The BMI (p = 0.180), waist-to-hip ratio (p = 0.280), neck-to-waist ratio (p = 0.070), maxillary depth angle (p = 0.250), and upper/lower face height ratio (p = 0.070) showed no significant differences between groups. CONCLUSIONS: Compared to the control group, the OSA group exhibited a greater mean difference in neck circumference, the only anthropometric measurement with high certainty of evidence.

OBJECTIVE: To summarize the scientific evidence on the prevalence of maxillary sinus hypoplasia (MSH) and associated anatomical variations as assessed by computed tomography scans. STUDY DESIGN: This PROSPERO-registered systematic review followed the recommendations of the PRISMA guidelines. Search algorithms were constructed for each of the six databases and gray literature. After screening the references (Rayyan®), the extracted data were meta-analyzed according to a random-effects model. The joanna briggs critical appraisal tool assessed the methodological quality of the included studies. The GRADE approach was used to estimate the certainty of the evidence. RESULTS: From a total of 2781 studies screened, 22 were considered for four meta-analysis. The prevalence of MSH in 7358 patients was 5.65% (CI95% = 4.07-7.47%) with significant heterogeneity between studies (p < 0.001, I2 = 89.30%). MSH was identified in 295 patients, of whom 82.38% (CI95% = 75.82-88.09%) had unilateral hypoplasia and 17.62% (CI95% = 11.91-24.18%) bilateral hypoplasia with moderate heterogeneity between studies (p < 0.0503, I2 = 42.87%). The prevalence of MSH in 9998 maxillary sinuses was 3.77% (95% CI = 2.44-5.38%), with significant heterogeneity between studies (p < 0.001, I2 = 92.84%). Hypoplastic/aplastic uncinate process, concha bullosa and paradoxical concha were the most reported anatomical variations. The studies presented a low-moderate methodological quality. The certainty of the evidence was very low to moderate. CONCLUSION: The prevalence of maxillary sinus hypoplasia observed was 5.65%, with most cases being unilateral.

ABSTRACT Sex determination plays a crucial role in the post-mortem identification of human remains. One effective approach for obtaining sex-related data is to use measurements of anatomical structures such as the mandible. This study aimed to evaluate the potential of mandibular radiomorphometric indices from panoramic radiographs (PRs) for the identification of sexual dimorphism. The study sample included 300 PRs of individuals aged 51 to 80 years from the northeastern region of Brazil. Four linear measures and three numerical indices were analyzed with Inkscape® version 1.0.1 for Windows by two blinded evaluators. After statistical analysis, the results showed that the linear measurements obtained from PRs are a reliable method for sex identification. However, the calculated indices of these measurements exhibited lower efficacy for the same purpose. Therefore, PRs proved to be a valuable method for sexual identification through mandibular assessment.
RESUMO A determinação do sexo é um dado importante para a identificação post-mortem de um indivíduo ou de restos mortais humanos. Uma maneira de adquirir dados quanto ao sexo é utilizar mensurações de estruturas como a mandíbula. O objetivo principal deste estudo é avaliar a utilização de índices radiomorfométricos de mandíbulas para a identificação de dimorfismo sexual, através de radiografias panorâmicas. O estudo foi realizado em exames radiográficos panorâmicos de 300 indivíduos entre 51 e 80 anos, residentes do Nordeste brasileiro. Foram analisadas quatro medidas lineares e três índices numéricos no software Inkscape® versão 1.0.1 para Windows, por dois avaliadores cegos. Após análise estatística, os resultados demostraram que as medidas lineares obtidas se configuram como um método seguro para a identificação sexual. Entretanto, os índices obtidos através destas medidas demostraram menor eficiência para o mesmo fim. Logo, as radiografias panorâmicas podem ser utilizadas como método eficaz para a obtenção da caracterização sexual através da mandíbula.
RESUMO
Abstract This cross-sectional study evaluated the association between salivary immunoglobulins, plaque index, and gingival index in Brazilian children with and without type 1 diabetes mellitus (DM1). The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for the reporting of observational studies was followed. The DM1 group had 38 children, and an equal number of volunteers matched by sex and age were recruited as controls. Clinical examination was performed for plaque index and gingival index determination. Non-stimulated whole saliva was collected. Concentrations of IgA, IgG, and IgM were determined by ELISA test. Data were tested by the Kolmogorov-Smirnov, Mann-Whitney, and Spearman tests and a multiple linear regression model (p<0.05) was performed. Gingival index was higher in the Control (DM1: 0.16±0.17; Control: 0.24±0.23, p=0.040). In DM1, there was a correlation between IgA and age (rho=0.371, p=0.024), IgM and IgG (rho=0.459, p=0.007), and IgM and gingival index (rho=0.394, p=0.014). In DM1, multiple linear regression showed that age (p=0.041; β=0.363), gingival index (p=0.041; β=0.398), and plaque index (p=0.008; β=-0.506) were good predictors of IgA levels in saliva. Thus, IgA was the only researched immunoglobulin that was directly associated with plaque and gingival indices in Brazilian children with DM1, but not in control subjects.
RESUMO
Objective: To systematically summarize the evidence for photobiomodulation therapy (PBMT) in the prevention and treatment of oral mucositis (OM) in patients undergoing cancer treatment. An electronic search was conducted in 8 databases and grey literature. Background: PBMT is recommended for the management of OM resulting from cancer treatment, with several systematic reviews (SRs) being published in recent years on this topic. Methods: Only SRs with outcomes from clinical trials were included, with no language or year restriction. The AMSTAR 2 tool was used to assess the methodological quality of the SRs. Results: Five thousand eight hundred fifty-six references were found, and 16 were selected for this review. OM prevention and treatment were favorable for PBMT in most studies, with a significant reduction in OM severity. Most studies obtained moderate confidence. Conclusions: PBMT represents an effective strategy in the management of OM, and this evidence is supported by studies with acceptable methodological quality.

OBJECTIVE: This systematic review aimed to answer whether, in (P) individuals undergoing orthognathic surgery, (I) low-level laser therapy (LLLT) during or shortly after the surgical procedure compared to (C) pharmacologic therapy alone or no therapy for improvement of post-intervention complications relieves (O) postoperative inflammatory events in (S) randomized clinical trials. MATERIAL AND METHODS: A preliminary electronic search was conducted for references with language following a Latin (Roman) alphabet in seven databases index, and gray literature without restriction on language or publication period. Risk of bias was performed by RoB 2.0 tool, and meta-analysis used mean differences (MD) for edema and mouth opening and standardized mean differences (SMD) for pain scores (p < 0.05, Revman®). RESULTS: A total of 91 control patients and 114 LLLT patients were included. The wavelengths ranged from 660 to 940 nm, and the applied energy density was between 5 and 100 J/cm2 at mostly extraoral distributed points. LLLT significantly reduced edema (MD = - 4.27, CI95% - 5.13 to - 3.41 mm) in the period from 5 days to 2 weeks postoperatively (p < 0.001) and showed strongly reduced pain scores (SMD = - 1.37, I95% = - 1.99 to - 0.75) between 1 day and 5 weeks (p < 0.001), without significantly interfering with mouth opening (p = 0.110). Despite the low risk of bias, high heterogeneity among studies (I2 > 70%) and small sample sizes made the certainty of GRADE evidence low. CONCLUSION: This SR demonstrated that LLLT effectively controls pain and edema after orthognathic surgery. CLINICAL RELEVANCE: Systematic review that summarizes the use of photobiomodulation on orthognathic surgery.
RESUMO
OBJECTIVE: The objective of this systematic review was to determine whether oral and dental hygiene protocols (DHPs) reduce the incidence and severity of oral mucositis (OM) during antineoplastic treatment. MATERIALS AND METHODS: This PROSPERO-registered systematic review (CRD42021295322) was based on searches of publicly accessible databases, including PubMed, Scopus, Web of Science, LILACS, EBSCOhost, LIVIVO, Embase, and gray literature (Google Scholar, ProQuest, and Energy) until December 2021. Twenty-five articles from these searches and 14 articles retrieved from the references therein were evaluated in this systematic review and meta-analysis. The risk of bias (RoB) was assessed using RoB-2 and ROBINS-I for randomized (RCT) and non-randomized (n-RCT) clinical trials, respectively. A meta-analysis was performed on RCTs and n-RCTs in two subgroups to evaluate oral mouth rinses or DHP. GRADE-pro was used to assess the degree of certainty of the evidence. RESULTS: Of the 3367 articles retrieved, 25 RCTs and 14 n-RCTs involving 2109 and 754 patients, respectively, were included in the analyses. RoB was low for RCTs and moderate-to-very severe for n-RCTs. High heterogeneity and publication RoB were identified. In RCTs, mouth rinses (p = 0.830) and DHP (p = 0.100) did not reduce the incidence of OM. However, mouth rinses strongly reduced the severity of OM (p < 0.001; Cohen's d = - 1.87, 95% confidence interval [CI] = - 2.49 to - 1.24). In non-RCTs, mouth rinses (p < 0.001) and DHP (p < 0.001) reduced the relative risk of OM 0.38 (95% CI = 0.24 to 0.59) and 0.64 (95% CI = 0.53 to 0.70) times, respectively. In addition, DHP strongly reduced OM severity (Cohen's d = - 0.81, 95% CI = - 1.03 to - 0.59). GRADE-pro showed high certainty of OM severity and incidence in RCTs and non-RCTs, respectively, and low (OM incidence in RCTs) to very low (OM severity in non-RCTs) certainty in other outcomes. CONCLUSION: DHPs strongly reduce the severity and moderately reduce the incidence of OM. However, further studies with low heterogeneity are needed to validate these findings.

This study aimed to evaluate the scientific evidence on the effect of preemptive drug coadministration (PDC) for relieving inflammatory events (pain, swelling, and trismus) in mandibular third molar surgery. A PROSPERO-registered systematic review (CRD42022314546) was conducted according to the PRISMA guide. The searches were carried out in six primary databases and the gray literature. Studies not written in languages with the Latin alphabet (Roman) were excluded. Potential randomized controlled trials (RCTs) were screened for eligibility. Cochrane's Risk of Bias-2.0 (RoB) tool was assessed. A synthesis without meta-analysis (SWiM) based on a vote counting and an effect direction plot. Nine studies (low RoB) fulfilled the eligibility criteria and were included for data analysis, with a total of 484 patients. PDC mostly involved corticosteroids (Cort) and non-steroidal anti-inflammatory drugs (NSAIDs). PDC of Cort and other drugs mainly reduced pain scores (6 and 12 h postoperatively) and swelling (48 h postoperatively). PDC of NSAIDs and other drugs mainly reduced pain scores at 6, 8, and 24 h follow-up; swelling and trismus intensity ameliorated at 48 h postoperatively. The most frequently prescribed rescue medication was paracetamol, dipyrone, and paracetamol plus codeine. Results from individual studies have shown reduced consumption of ingested rescue analgesics. In summary, the available evidence from clinical trials included in this SWiM suggests that PDC may provide benefits in reducing the severity of inflammatory outcomes related to mandibular third molar surgery, especially the pain scores in the first hours after surgery, and the rescue analgesic consumption during the postoperative period.

PURPOSE: Bone grafting is fundamental in the treatment of cleft patients, and several grafting materials have been used for this purpose. The objective of this study is to evaluate the effectiveness of autogenous bone graft from the chin in the reconstruction of cleft alveolus. METHODS: Searches were performed in six databases (PubMed, Scopus, Cochrane, LILACS, Embase, and Google Scholar) by two researchers individually until July 2022. This study was registered in the International Prospective Register of Systematic Reviews (CRD42021267954) and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The predictor variable is reconstruction technique, grouped into three levels: autogenous genial grafts, other endochondral autogenous grafts, and bio- or tissue-engineered materials. The outcome variables were alveolar cleft healing rate and bone height. The secondary variables were complications that included infections, necrosis, paresthesia, and dehiscence. Data analysis included the risk of bias and assessment of the certainty of evidence by the risk of bias in nonrandomized studies of interventions and grading of recommendations, assessment, development, and evaluation tools, respectively. The meta-analysis was performed with heterogeneity based on random effects of I2 and 95% confidence. RESULTS: In the initial search, 4,833 articles were found, and 10 of them were included in this systematic review. The included studies were from six countries on three different continents, with a sample of 692 patients. It was observed that the chin bone graft (214 patients) when compared to the endochondral bone graft (386 patients) reduced by 0.42 [confidence interval 95% = 0.18, 0.95] times the prevalence of bone resorption (P = .040 and I2 = 70%) analyzed in radiographic images. Two studies evaluated the bone filling through computed tomography, and there was no statistically significant difference between the groups (P = .340, I2 = 0%). Only two studies had a low risk of bias. CONCLUSION: Based on a low certainty of evidence, the chin autogenous bone graft proved to be similar to the endochondral graft in the reconstruction of the cleft alveolar; however, the limited number of studies with high heterogeneity and an uncertain risk of bias decreased the strength of the results found in this systematic review. New controlled primary studies should be carried out with the purpose of safely determining the effectiveness of chin bone grafts for the reconstruction of cleft alveolar.

Dental erosion is a chemical process characterized by acid dissolution of dental hard tissue, and its etiology is multifactorial. Dietary polyphenols can be a strategy for dental erosion management, collaborating to preserve dental tissues through resistance to biodegradation. This study describes a comprehensive review to interpret the effects of polyphenols on dental erosion of pre-clinical models with in situ designs and simulated acid attacks on enamel and dentin samples. We aim to evaluate evidence about Polyphenols' effects in the type of dental substrate, parameters of erosive cycling chosen in the in situ models, and the possible mechanisms involved. An evidence-based literature review was conducted using appropriate search strategies developed for main electronic databases (PubMed, Scopus, Web of Science, LILACS, EMBASE, LIVIVO, CINAHL, and DOSS) and gray literature (Google Scholar). The Joanna Briggs Institute checklist was used to evaluate the quality of the evidence. From a total of 1900 articles, 8 were selected for evidence synthesis, including 224 specimens treated with polyphenols and 224 control samples. Considering the studies included in this review, we could observe that polyphenols tend to promote a reduction in erosive and abrasive wear compared to control groups. However, as the few studies included have a high risk of bias with different methodologies and the estimated effect size is low, this conclusion should not be extrapolated to clinical reality.
