Top 100 most-cited scientific articles in regenerative endodontics 2019-2023: A bibliometric analysis.

BACKGROUND: Bibliometric analysis is a critical indicator of the influence and relevance of scientific papers, whilst also highlighting key contributors and gaps in knowledge in a scientific field. OBJECTIVES: To update and analyse the 100 most-cited papers in regenerative endodontics from 2019 to 2023. METHODS: A search of the most-cited recent papers focusing on regenerative endodontics using journals included in the category, 'Dentistry, Oral Surgery & Medicine', in the Clarivate Web of Science database from 2019 to 2023 was performed. Three researchers conducted the study selection and data extraction. Data extraction included publication title and year, authors, number and mean number of citations, institution, country and continent, study design, journal title, keywords and research topic. Citation counts were also collected in Google Scholar and Scopus databases. Graphical bibliometric networks were created using VOSviewer software. RESULTS: The number of citations of the 100 most-cited articles ranged from 6 to 85. Most were published in 2020 (n = 48), principally in the Journal of Endodontics (47%), followed by International Endodontic Journal (13%), Journal of Dental Research (6%) and Dental Materials (6%). Laboratory study was the most common study design amongst the included papers (n = 47), followed by narrative reviews (n = 17) and observational studies (n = 16). The most frequent first author on the top three most-cited papers was Hacer Aksel, whilst Adham A. Azim (n = 6; 89 citations) contributed most to the top 100 articles. The institution from which most articles originated was the University of Hong Kong (China) (n = 5; 81 citations), whereas the corresponding authors were predominantly from the United States of America (USA) (n = 31; 560 citations). The VOSviewer map of co-authorship demonstrated research collaborative clusters. 'Regenerative endodontics' and 'stem-cells' were the most employed keywords (37 and 36 occurrences respectively). DISCUSSION: The current study was designed not only to showcase the most influential papers in regenerative endodontics since 2019 but also to provide a better understanding of global research in this area over the last five years. CONCLUSIONS: This bibliometric analysis highlighted papers, authors, institutions and keywords in regenerative endodontics. The 100 most-cited papers primarily consisted of laboratory studies published in the USA, focusing on evaluating biomaterials and scaffold design strategies in contact with stem cells. Clinical studies and systematic reviews representing higher levels of scientific evidence are currently not the most influential in the regenerative endodontic field.

Pyrones isolated from Annona acutiflora exhibit promising cytotoxic effects on cancer cell lines.

This work discusses the ongoing challenge of cancer, focusing on therapy issues such as chemotherapy resistance and adverse drug effects. It emphasizes the need for new anticancer agents with improved efficacy and fewer side effects, exploring natural products from plant sources. The Annonaceae family, specifically the Annona genus, is highlighted for its medicinal properties, including anti-inflammatory and anticancer effects. The study focuses on the isolation and elucidation of the substances present in Annona acutiflora leaves. The methodology involves chromatographic and spectroscopy techniques. The isolated compounds, (6S)-5'-oxohepten-1'E,3'E-dienyl)-5,6-dihydro-2H-pyran-2-one (1), (6R)-5'-oxohepten-1'Z,3'E-dienyl)-5,6-dihydro-2H-pyran-2-one (2) and (6R)-5'-oxohepten-1'Z,3'E-dienyl)-5,6-dihydro-2H-pyran-2-one (3) were investigated for cytotoxicity assays on cancer cell lines and normal cells. Results show promising cytotoxic activity, particularly with compound 3, demonstrating potential activity against oral cancer (43.18µM), hepatocarcinoma (17.24µM), melanoma (5.39µM), and colon cancer (59.03µM). The compound outperforms carboplatin in selectivity against oral cancer (S.I. 2.15) and melanoma (S.I. 17.22). The study concludes by suggesting the potential of these α-pyrones as effective and less toxic alternatives for cancer therapy.

Abietane Diterpenes from Medusantha martiusii and Their Anti-Neuroinflammatory Activity.

Seven new abietane diterpenoids, comprising medusanthol A-G (1-3, 5, 7-9) and two previously identified analogs (4 and 6), were isolated from the hexane extract of the aerial parts of Medusantha martiusii. The structures of the compounds were elucidated by HRESIMS, 1D/2D NMR spectroscopic data, IR spectroscopy, NMR calculations with DP4+ probability analysis, and ECD calculations. The anti-neuroinflammatory potential of compounds 1-7 was evaluated by determining their ability to inhibit the production of nitric oxide (NO) and the proinflammatory cytokine TNF-α in BV2 microglia stimulated with LPS and IFN-γ. Compounds 1-4 and 7 exhibited decreased NO levels at a concentration of 12.5 µM. Compound 1 demonstrated strong activity with an IC50 of 3.12 µM, and compound 2 had an IC50 of 15.53 µM; both compounds effectively reduced NO levels compared to the positive control quercetin (IC50 11.8 µM). Additionally, both compounds significantly decreased TNF-α levels, indicating their potential as promising anti-neuroinflammatory agents.

Influence of Major Polyphenols on the Anti-Candida Activity of Eugenia uniflora Leaves: Isolation, LC-ESI-HRMS/MS Characterization and In Vitro Evaluation.

The content of chemical constituents in Eugenia uniflora leaf extracts correlates positively with biological activities. The experimental objective was to carry out the phytochemical screening and purification of the major polyphenols from the leaves of E. uniflora. In addition, the anti-Candida activity of the hydroalcoholic extract, fraction, subfractions and polyphenols purified were evaluated. After partitioning of the extract with ethyl acetate, the fractions were chromatographed on Sephadex® LH-20 gel followed by RP-flash chromatography and monitored by TLC and RP-HPLC. The samples were characterized by mass spectrometry (LC-ESI-QTOF-MS2) and subjected to the microdilution method in 96-well plates against strains of C. albicans, C. auris, and C. glabrata. Myricitrin (93.89%; w/w; m/z 463.0876), gallic acid (99.9%; w/w; m/z 169.0142), and ellagic acid (94.2%; w/w; m/z 300.9988) were recovered. The polyphenolic fraction (62.67% (w/w) myricitrin) and the ellagic fraction (67.86% (w/w) ellagic acid) showed the best antifungal performance (MIC between 62.50 and 500 µg/mL), suggesting an association between the majority constituents and the antifungal response of E. uniflora derivatives. However, there is a clear dependence on the presence of the complex chemical mixture. In conclusion, chromatographic strategies were effectively employed to recover the major polyphenols from the leaves of the species.

Factors associated with the impact of fixed appliance orthodontic treatment on the oral health-related quality of life of adolescents: Assessment using a condition-specific instrument.

Background: Oral outcomes may have an impact on quality of life. The aim of this study was to assess factors associated with the impact of fixed appliance orthodontic treatment on the oral health-related quality of life (OHRQoL) of adolescents. Material and Methods: Individuals aged 10 to 18 years undergoing orthodontic treatment were included. Data regarding adolescents' sex and age, parental schooling, family income, and number of individuals who depend on income were collected. Clinical variables, orthodontic tooth extraction and malocclusion severity were also analyzed. OHRQoL was assessed with a questionnaire with items distributed across nine domains: aesthetics, functional limitation, diet, hygiene, maintenance, physical impact, social impact, time constraints, and transport/cost inconveniences. The higher the score, the more negative the adolescent's perception of his/her OHRQoL. Statistical analysis was performed. Results: Seventy-five adolescents participated. Individuals aged ≤12 years had a more negative perception of the diet domain (p=0.026). Individuals whose parents/guardians had ≥8 years of schooling had a more negative perception of the impact on the hygiene domain (p<0.024). Individuals whose families had an income of ≤2 salaries had a more negative perception of the maintenance domain (p=0.016). Girls had a more negative perception of the physical impact domain (p<0.018). Girls (p=0.011), adolescents whose families had an income of ≤2 salaries (p=0.003), and adolescents who had severe malocclusion (p=0.026) had a more negative perception of the transport/cost inconveniences domain. Girls had a significantly higher overall score in response to the questionnaire than boys (p=0.041). Conclusions: Adolescents' sex, age, and malocclusion as well as parental education and family income were associated with the impact of orthodontic treatment on adolescents' OHRQoL. Key words:Adolescent, Quality of life, Orthodontic treatment, Fixed appliance.

Late Eruption of Mandibular Central Incisor in Small for-Gestational-Age Infants: A Cohort Study.

Purpose: To evaluate the chronology of the eruption of primary mandibular central incisors in infants born preterm and with low weight (PLBW) and its association with weight/length ratio for gestational age (GA) at birth, individual characteristics and hospitalization at birth. Methods: A cohort of 46 infants was followed at a multidisciplinary reference center at a university hospital in Belo Horizonte, Brazil. The inclusion criteria were infants born preterm with low/very low/extreme low birth weight and at least four months of age. Oral clinical examinations were carried out by a calibrated dentist for a total of eight months, with a one-month interval between each examination, to verify the chrono- logy of eruption of the primary mandibular central incisors. Caregivers completed a sociodemographic and health questionnaire. Data on neonatal hospitalization were collected from medical records. Data were analyzed with the Kaplan-Meier method and log rank test, and bivariate analysis was done using the Mann-Whitney method and Kruskal-Wallis test (P <0.05). Results: The average age at eruption of primary lower central incisors was 11 months for both sexes. No association was found between tooth eruption and child hospitalization or individual characteristics (P >0.05). Infants large for gestational age had earlier tooth eruption (9.3±1.41 months) than infants small for gestational age (13.6±3.29 months; P <0.05).Conclusion: The most likely age for the eruption of the first primary teeth in infants born preterm and with low weight was 11 months, and there was no influence of individual characteristics and hospitalization at birth. Small-for-gestational age infants experienced delayed tooth eruption compared to large-for-GA infants.

Bacillus velezensis iturins inhibit the hemolytic activity of Staphylococcus aureus.

Bovine mastitis caused by S. aureus has a major economic impact on the dairy sector. With the crucial need for new therapies, anti-virulence strategies have gained attention as alternatives to antibiotics. Here we aimed to identify novel compounds that inhibit the production/activity of hemolysins, a virulence factor of S. aureus associated with mastitis severity. We screened Bacillus strains obtained from diverse sources for compounds showing anti-hemolytic activity. Our results demonstrate that lipopeptides produced by Bacillus spp. completely prevented the hemolytic activity of S. aureus at certain concentrations. Following purification, both iturins, fengycins, and surfactins were able to reduce hemolysis caused by S. aureus, with iturins showing the highest anti-hemolytic activity (up to 76% reduction). The lipopeptides showed an effect at the post-translational level. Molecular docking simulations demonstrated that these compounds can bind to hemolysin, possibly interfering with enzyme action. Lastly, molecular dynamics analysis indicated general stability of important residues for hemolysin activity as well as the presence of hydrogen bonds between iturins and these residues, with longevous interactions. Our data reveals, for the first time, an anti-hemolytic activity of lipopeptides and highlights the potential application of iturins as an anti-virulence therapy to control bovine mastitis caused by S. aureus.

Impact of treament with orthodontic aligners on the oral health-related quality of life.

BACKGROUND: There is an increasing interest in information on the effects of orthodontic aligners on the oral health-related quality of life (OHRQoL) of people. AIM: To compare the impact of orthodontic aligners versus conventional fixed appliances on OHRQoL, using a validated tool and controlling for sociodemographic and clinical variables. METHOD: Sixty-one individuals participated in this study. Group 1 (G1) consisted of 33 individuals under treatment with orthodontic aligners and Group 2 (G2) comprised 28 individuals under treatment with conventional fixed appliances. OHRQoL was evaluated with the Oral Health Impact Profile (OHIP-14) in which 14 items are distributed across seven dimensions: functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. The higher the score, the more negative is the perception of the individual regarding his/her OHRQoL. Descriptive statistics, Mann-Whitney test, and Poisson regression were performed. Effect Size (ES) and Minimal Clinically Important Difference (MCID) were also determined. RESULTS: Participants' mean age was 30.69 years. Individuals in G1 had a significantly lower score for physical pain and the total score of OHIP-14 compared to individuals in G2 (p < 0.05). The ES was large (ES = 0.74) for physical pain and moderate (ES = 0.46) for the total score. The ES was moderate for physical disability (ES = 0.50). The difference between groups for physical pain (1.30) and for physical disability (0.90) was greater than the MCID (0.87 and 0.88, respectively). Poisson regression showed that G2 individuals showed a score for physical pain 1.39 times higher than those of G1 in the adjusted model (OR = 1.39, [1.03-1.89], p = 0.031). CONCLUSION: Those under treatment with orthodontic aligners have a more positive perception of OHRQoL compared to those wearing fixed appliances.

Dental caries and developmental defects of enamel in cerebral palsy: A meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to compare the occurrence of dental caries and developmental defects of enamel (DDE) in individuals with and without cerebral palsy (CP). MATERIALS AND METHODS: We conducted searches across five databases and the grey literature. Data were organized using EndNote 20. Reporting followed the MOOSE checklist. A random-effects model meta-analyses were conducted using RStudio, presenting results as mean difference (MD), odds ratio (OR), and 95% confidence interval (CI). The risk of bias of studies was analyzed using the Newcastle-Ottawa Scale, and the certainty of evidence was assessed using GRADE. RESULTS: Among 1336 identified records, 25 studies involving 59,997 participants (mean age: 11.1 years) were included. Data of 12 were pooled into meta-analyses. No significant differences were found between CP and non-CP individuals across indices: DMFT (k = 7) (MD = 0.31; 95% CI [-0.42-1.05]), dmft (k = 4) (MD = 0.31; 95% CI [-0.50-1.14]), DMFS (k = 2) (MD = -0.61; 95% CI [-20.56-19.33]), dmfs (k = 3) (MD = 0.54; 95% CI [-1.09-2.17]), and DDE (k = 3) (OR = 0.80, 95% CI [0.09-7.31]). The certainty of evidence was very low. CONCLUSION: Individuals with CP do not appear to differ significantly from those without CP in terms of dental caries experience and DDE.

Identification of Epstein-Barr virus after topical treatment for oral hairy leukoplakia: A preliminary study.

BACKGROUND: This study evaluated the presence of Epstein-Barr virus type 1 (EBV-1) DNA in patients living with HIV, before and after three different topical therapy protocols for oral hairy leukoplakia (OHL). METHODS: The sample consisted of five patients treated with topical solution of 25% podophyllin resin; six with 25% podophyllin resin plus 5% acyclovir cream; and four with 25% podophyllin resin plus 1% penciclovir cream. DNA was extracted from OHL scrapings and amplified by the PCR using specific primers for EBV-1 (EBNA-1). RESULTS: Clinical healing of OHL lesions was observed across all treatment groups over time. At baseline, EBNA-1 was detected in all OHL lesions. After treatment, OHL samples from three patients treated with 25% podophyllin resin plus 5% acyclovir cream and from one patient treated with 25% podophyllin resin plus 1% penciclovir cream exhibited negative EBNA-1 viral gene encoding. Despite the clinical resolution of OHL, 11 patients (73.3%) showed EBNA-1 positivity immediately after the lesion disappeared. Three patients (20%) treated with podophyllin resin displayed both EBNA-1 positivity and a recurrence of OHL, in contrast to no recurrence in the other two groups. CONCLUSIONS: These findings suggest potential associations between treatment formulations, EBNA-1 persistence, and the recurrence of OHL lesions.

Experience with 808-nm diode laser in the treatment of 47 cases of oral vascular anomalies.

Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6.4%), and hemangiomas (2.1%) with a mean size of 7.1 (±4.9) mm were the conditions treated. OVA presented as a nodular lesion (63.8%) involving mainly the lower lip (46.8%). Pulsed laser mode was used as standard and the number of applications varied from one to four sessions, with the majority requiring only one (83%) FDIP session. Kaplan-Meier analysis revealed that complete clinical healing can occur on the 15th day (n=9/29.5%), followed by the 20th (n=6/45.5%), and 30th (n=7/70.5%) days. Postoperative edema was observed in 31 (66%) patients, and recurrence of the lesion occurred in two (4.2%). Based on the data on complete clinical healing, minimal patient discomfort, and satisfactory esthetic results, we can confirm that FDIP by diode laser is a promising candidate for the safe and efficacious treatment of OVA.

Oral lesions of systemic lupus erythematosus: A collaborative Latin American study.

BACKGROUND: Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disease that may affect the oral mucosa. The variable spectrum of oral lesions observed in SLE can pose challenges in diagnosis, particularly when the lesions occur in isolation. The aim of this study was to describe the oral lesions occurring in patients with SLE from Latin America. METHODS: This collaborative record-based study involving 11 oral and maxillofacial pathology and medicine services across Venezuela, Argentina, Chile, Brazil, and Mexico describes the clinicopathological profile of SLE-related oral lesions. RESULTS: Seventy patients with SLE and oral lesions were included in the study. The majority were females (75.7%; female/male ratio: 3.1:1) and white (62.1%), with a mean age of 38.4 years (range: 11-77 years). The most common site of oral lesions was the hard/soft palate (32.0%). Clinically, oral lesions predominantly presented as ulcers (26.6%), erosions (26.6%), and white lesions (23.4%). Isolated oral lesions occurred in 65.2% of individuals, while cutaneous manifestations occurred in 80.3%. The main clinical diagnostic hypothesis in 71.4% of cases was an immune-mediated disease. Oral biopsies followed by histopathological analysis were performed in 50 cases. CONCLUSION: Oral lesions of SLE exhibit a variety of clinical and histopathological features. A key point in diagnosis is that unusual oral changes without an obvious local cause may indicate a possible systemic condition presenting with oral lesions. A multidisciplinary approach, which includes regular oral examination, is warranted to identify oral lesions and provide treatment.

Diagnosis and rehabilitation of an infant with palatal mucormycosis: A clinical report and systematic literature review.

STATEMENT OF PROBLEM: Oral mucormycosis is uncommon in pediatric patients with hematolymphoid diseases. Prosthetic rehabilitation is challenging, and protocols are scarce in the literature. PURPOSE: The purpose of this clinical report and systematic literature review of case reports and case series was to describe the clinicopathologic aspects of oral mucormycosis and the interim prosthetic rehabilitation of an affected infant. MATERIAL AND METHODS: The clinical lesions were ulcerative and necrotic with underlying bone exposure that affected the hard palate. The affected area underwent surgical debridement, and histopathologic analysis was performed. A literature search in PubMed/MEDLINE, Embase, Scopus, and Web of Science up to October 2023 was performed. RESULTS: The histopathological features were consistent with mucormycosis. Topical and systemic antifungals were prescribed. Tooth eruption was insufficient, and an acetate plate without clasp retention, but still with adequate retention, was fabricated. Articulatory, masticatory, and swallowing functions were restored, preventing the passage of food and fluids into the oroantral cavities. Twenty-five articles describing 26 patients with oral mucormycosis related to hematolymphoid disorders affecting the pediatric population were identified. None of the authors of these articles provided information about oral rehabilitation. CONCLUSIONS: Early diagnosis and treatment are essential to increasing the chances of survival for infants affected by oral mucormycosis. Custom-made rehabilitation should be provided to restore oral function and improve the patient's general health.

Evaluation of the Antiproliferative Potential of Yellow Jaboticaba (Myrciaria glazioviana) Extracts Against Human Cervical Cancer (HeLa cells line) and the Analysis of Their Chemical Composition by HPLC-HRESIMS.

Cervical cancer is a specific type of cancer that affects women around the world, with an incidence of 604 thousand new cases per year and 341 thousand deaths. There is a high demand for new effective antineoplastic drugs with few side effects. In this sense, recent research highlights the potential of compounds of natural origin in treating and preventing different types of cancer. Myrciaria glazioviana is a Brazilian native species belonging to the Myrtaceae family, which has previously described biological activities such as antimicrobial, anti-inflammatory, and antioxidant properties. This study aims to evaluate the anticancer activity of the dichloromethane extract (MGD) and ethyl acetate extract (MGA) of M. glazioviana leaves against human cervical cancer cell line (HeLa), as well as to identify their bioactive compounds. Using HPLC-HRESIMS technique, ten compounds were characterized in both samples: quinic acid, ellagic acid, Tri-O-methyl ellagic acid, two derivatives of Tetra-O-methyl flavellagic acid, quercetrin, Di-O-methyl ellagic acid, and three derivatives of pentamethyl coruleoellagic acid. Through MTT assays using HeLa cells and NIH/3T3 cells, it was observed that MGD and MGA were selective against tumor cells, with IC50 values of 24.31 and 12.62 µg/mL, respectively. The samples induced the tumor cell death by apoptosis, as evidenced by the activation of caspases 3/7, cell shrinkage, and pyknotic nuclei. Both samples were also able to inhibit the migration of HeLa cells after 24 hours of treatment, indicating a potential antimetastatic effect. Therefore, the present research highlights the antiproliferative and antimigratory potential of this species against HeLa cells.

Influence of dental bleaching on the pulp tissue: A systematic review of in vivo studies.

BACKGROUND: Although several studies indicate the harmful effects of bleaching on pulp tissue, the demand for this procedure using high concentrations of hydrogen peroxide (HP) is high. OBJECTIVES: To investigate the influence of bleaching on the pulp tissue. METHODS: Electronic searches were conducted (PubMed/MEDLINE, Scopus, Cochrane Library and grey literature) until February 2021. Only in vivo studies that evaluated the effects of HP and/or carbamide peroxide (CP) bleaching gels on the inflammatory response in the pulp tissue compared with a non-bleached group were included. Risk of bias was performed according to a modified Methodological Index for Non-Randomized Studies scale for human studies and the Systematic Review Centre for Laboratory Animal Experimentation's RoB tool for animal studies. Meta-analysis was unfeasible. RESULTS: Of the 1311 studies, 30 were eligible. Of these, 18 studies evaluated the inflammatory response in animal models. All these studies reported a moderate-to-strong inflammatory response in the superficial regions of pulp, characterized by cell disorganization and necrotic areas, particularly during the initial periods following exposure to 35%-38% HP, for 30-40 min. In the evaluation of human teeth across 11 studies, seven investigated inflammatory responses, with five observing significant inflammation in the pulp of bleached teeth. In terms of tertiary dentine deposition, 11 out of 12 studies noted its occurrence after bleaching with 35%-38% HP in long-term assessments. Additionally, three studies reported significant levels of osteocalcin/osteopontin at 2 or 10 days post-treatment. Other studies indicated an increase in pro-inflammatory cytokines ranging from immediately up to 10 days after bleaching. Studies using humans' teeth had a low risk of bias, whereas animal studies had a high risk of bias. DISCUSSION: Despite the heterogeneity in bleaching protocols among studies, High-concentrations of HP shows the potential to induce significant pulp damage. CONCLUSIONS: High-concentrations of bleaching gel increases inflammatory response and necrosis in the pulp tissue at short periods after bleaching, mainly in rat molars and in human incisors, in addition to greater hard tissue deposition over time. However, further well-described histological studies with long-term follow-up are encouraged due to the methodological limitations of these studies. REGISTRATION: PROSPERO (CRD42021230937).

Overweight/obesity and dental caries in Brazilian children and adolescents: a systematic review and meta-analysis.

This review aimed to assess the association between overweight/obesity and dental caries in Brazilian children/adolescents. Searches were performed in the Web of Science, Scopus, Cochrane, PubMed, Embase and SciELO, Lilacs and Open Grey literature databases up to June 2022. The Joanna Briggs Institute checklist for analytical cross-sectional studies, the checklist for cohort studies, and the checklist for case-control studies were used. A total of 41 publications were included, and 15 meta-analyses were performed. The authors analyzed the differences in weighted mean difference (MD) and odds ratios (OR), and their corresponding confidence intervals (CI) (95%) for dental caries among eutrophic and obese and/or overweight children/adolescents. Meta-analyses showed that there was no association between overweight and/or obesity and dental caries in Brazilian children/adolescents for most anthropometric reference curves using BMI (Body Mass Index). A greater experience of dental caries was associated with well-nourished adolescents in permanent dentition, compared with obese individuals in the same dentition, as classified by the CDC 2000 curve (OR = 2.53, 95% CI;1.49-4.29; p = 0.0006; I2 = 0%) in dichotomous outcome studies, and (MD = 0.61, 95%CI: 0.08-1.15; p = 0.02; I2 = 0%) in continuous studies. The strength of the evidence of the results was classified as very low, low or moderate. It was concluded that there is no association between overweight and/or obesity and dental caries in Brazilian children/adolescents for most anthropometric reference curves using BMI. A greater experience of dental caries was associated with well-nourished adolescents in permanent dentition, compared with obese individuals in the same dentition, as classified by the CDC 2000 curve.

Probable sleep and awake bruxism in adolescents: A path analysis.

BACKGROUND: Bruxism has a multifactorial etiology, including the influence of sleep characteristics and chronotypes. AIM: To identify the pathways that influence the occurrence of probable sleep bruxism (PSB) and probable awake bruxism (PAB) in adolescents. DESIGN: A total of 403 adolescents, aged 12-19 years, participated in the study. Parents/caregivers filled out a questionnaire about sociodemographic issues and the adolescent's health conditions, and the adolescents about sleep characteristics, occurrence of bruxism (based on previous study and the International Consensus of Bruxism), and chronotype (Circadian Energy Scale). Clinical examinations were performed. Statistical analysis included descriptive analysis and path analysis. RESULTS: PSB and PAB are related to each other, with moderate and positive correlation (ß = .390). Poor sleep quality and higher household income had a direct effect on both PSB (ß = -.138; ß = .123, respectively) and PAB (ß = -.155; ß = .116, respectively). Chronotype had a direct effect on PSB, in such a way that adolescents with a morningness chronotype tend to have PSB (ß = -.102). Adolescents that drool on the pillow (ß = .184) and/or have agitated sleep (ß = .104) tend to have PSB. CONCLUSION: Poor sleep quality, household income, morningness chronotype profile, drooling on the pillow, and agitated sleep influence the paths taken by PSB. PAB was influenced by the quality of sleep and family income.

Multidisciplinary Treatment in Patients with Craniofacial, Neurocognitive, and Neuromuscular Disorders with Obstructive Sleep Apnea: A Systematic Review of the Literature.

Obstructive sleep apnea (OSA) is a respiratory disorder that has a high prevalence in patients with craniofacial, neurocognitive, and neuromuscular disorders. Currently, the treatments for this population are diverse and depend on the individual conditions of the patient and the severity of the case. However, there are no multidisciplinary dental treatment guidelines. The aim of the present study was to determine the multidisciplinary dental treatment alternatives in patients with craniofacial, neurocognitive, and neuromuscular disorders with a diagnosis of OSA through evidence-based medicine. A systematic review of the literature has been performed by searching scientific articles in the PubMed, Cochrane, Ovid, ScienceDirect and Scopus databases, through controlled and uncontrolled language. Articles were classified according to the level of evidence and grades of recommendation through the Scottish Intercollegiate Guidelines Network. A total of 19,439 references were identified, of which 15 articles met the predetermined requirements to be included in the investigation. The articles included for this systematic review showed that mandibular distraction osteogenesis and adenotonsilectomy are the first-choice therapies for craniofacial and neurocognitive disorders. However, for neuromuscular disorders, the findings reported were not enough to provide information about surgical or nonsurgical alternatives. Despite the reported high frequency of OSA in those children with craniofacial, neurocognitive, and neuromuscular disorders, the evidence on the surgical and nonsurgical therapeutic success for OSA in these patients is scarce. It is necessary to perform future studies to investigate successful therapies for OSA in children. [Pediatr Ann. 2024;53(2):e62-e69.].

Oral cancer and oral potentially malignant disorders in patients with Fanconi anemia - A systematic review.

The purpose of the present study was to perform a systematic review focusing on oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD) in Fanconi anemia (FA) individuals. Electronic searches were undertaken in five databases supplemented by manual scrutiny and gray literature. Case reports and/or cases series were included. The searches yielded 55 studies describing 112 cases of OSCC (n = 107) and/or OPMD (n = 5) in FA individuals. The mean age at diagnosis of OSCC/OPMD was 27.1 (±9.6) years, and females (51.8 %) were slightly more affected. Ulcer (n = 37) or mass (n = 25) were described as clinical presentations for OSCC and OPMD. White lesions (n = 4) were the most common manifestation in OPMD. Tongue (47.2 %) was the most frequent location. Sixty-one (54.5 %) individuals underwent HSCT. Surgical resection (n = 75) was the main treatment adopted. The estimated rate of OPMD malignant transformation was 1.8 % and recurrences following OSCC excision occurred in 26.8 % of individuals. Overall, at 60 months of follow-up, the probability of survival fell to 25.5 % and at 64 months the probability of recurrence increased to 63.2 %. The present data support the need for strict surveillance of patients with FA, even in the absence of OPMD, for early OSCC detection and reduction of mortality.

Ameloblastic carcinoma: A systematic review.

BACKGROUND: Ameloblastic carcinoma (AC) is the most common odontogenic malignancy, constituting approximately 30% of cases in this category. Literature is sparse on malignant odontogenic neoplasms, with a large proportion of current knowledge derived from case reports or small case series. METHODS: A systematic review of case series/case reports of AC was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Statement guidelines. Demographic and clinical information, including duration of the lesion, location, clinical presentation and radiologic features, were analysed. Additionally, the origin of the lesion (primary/secondary), Ki-67 proliferation index, treatment performed, metastasis, tumour recurrence and prognosis were collected for analysis. RESULTS: A total of 126 studies, including 285 individual cases of AC, were included in this review. Patients presented with a near-equal distribution of painless and painful swellings. ACs presented at a median age of 45 years, with a male-to-female ratio of 1:2. The mandible was most frequently involved, with rare cases extending to involve more than one region, including crossing the midline. Although most lesions presented with poorly-demarcated borders (52.6%), unilocular lesions with well-demarcated borders (47.4%) comprised a substantial number in the sample. The proliferation index was only reported in 27 cases, with a mean score of 42% and a wide range. The probability of tumour recurrence increased, and the survival probability decreased with prolonged follow-up duration. CONCLUSION: This study provides more comprehensive, up-to-date descriptive data on these rare odontogenic malignancies, aiding clinicians and Pathologists with the diagnosis and surgeons in their management of cases.
