EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2024; 28:1242-1258. [PMID: 38436158 DOI: 10.26355/eurrev_202402_35446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 03/05/2024]
Abstract
OBJECTIVE A biomaterial is any non-pharmaceutical substance or a mixture of synthetic or natural substances used independently or as part of a system for any amount of time with the aim of mending, supporting the growth, or replacing tissues, organs, or functions of the body. It is a non-renewable material that interacts with biological systems. The purpose of this study was to assess the advances in ceramic biomaterials and perform a bibliometric mapping of the literature on the subject. MATERIALS AND METHODS The Scopus database was used for manuscript screening (Elsevier, Amsterdam, The Netherlands). The effect of the scientific production has been assessed using scientometric citational metrics. RESULTS A total of 2,554 pieces of literature, including 2,234 papers, 170 conference proceedings, 109 reviews, 35 book chapters, 3 editorial letters, and 3 short surveys, were retrieved. Based on the research conducted, it is noted that ceramic materials are high-performing by being porous or glassy and can, therefore, serve as fillers, covering materials, and scaffolds in medicine and biotechnology. They are frequently employed not only in orthopedic and maxillofacial surgery but also in dentistry for dental prostheses. CONCLUSIONS Materials monitoring methods enable us to track the three-dimensional evolution of ceramics' volume, as well as flaws or micro-cracks.

Abstract
The emergence of the novel coronavirus and the pandemic resulting from its spread have led to significant negative impacts on health, economy, relationships, and others. Particularly in the field of hospital care, the need for a greater number of patients has led to a breakdown of the system. Gastrointestinal manifestations are common in SARS-COV 2 patients, while 10% of those who are sick exhibit symptoms only from gastrointestinal without any manifestation on the part of the respiratory tract. The main manifestations are nausea, vomiting, diarrhoea, and anorexia. It is also interesting to note that biochemical liver disorder is a frequent finding and is associated with a worse prognosis and higher probability admission to intensive care. It was also observed that RNA from the virus was found in the stool several days after the tests came back negative pulmonary secretions, while rectal swab virus detection methods were used with a lower but comparable sensitivity to that of nasal swabs. Gastrointestinal symptoms in SARS-COV 2 infection are common and their search should be part of the initial diagnosis approach and have a connection with the gut microbiota dysbiosis and this can lead to an alteration of the gut/liver axis.

The Correlation between Mandibular Arch Shape and Vertical Skeletal Pattern. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1926. [PMID: 38003975 PMCID: PMC10673071 DOI: 10.3390/medicina59111926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 10/18/2023] [Accepted: 10/20/2023] [Indexed: 11/26/2023]
Abstract
Background and Objectives: The aim of this study was to evaluate the correlation between the mandibular arch shape and the vertical skeletal pattern in growing patients. Materials and Methods: A total of 73 Caucasian patients (33 males and 40 females; mean age 9.4) were retrospectively enrolled from a pool of patients treated in chronological order at the Department of Orthodontics, University of Foggia, Italy, from April 2018 to December 2021. Each patient received a laterolateral radiograph and a digital scan of the dental arch. Eight cephalometric parameters (lower gonial angle, intermaxillary angle, divergence angle, Wits index, Jarabak ratio, OP-MP angle, PP-OP angle, and ANB) and five dental measurements (posterior mandibular arch width, anterior mandibular arch width, mandibular occlusal angle, posterior width on distobuccal molar cusps, and molar angle) were analyzed and then compared. A Spearman's rho correlation test between the cephalometric measurements and the dental measurements was performed. Statistical significance was set at p < 0.05. Results: A negative statistically significant correlation was found between the Jarabak ratio and the intermolar angle; a statistically significant correlation was also observed between the Wits index, the posterior mandibular width, and the occlusal mandibular angle; the ANB angle and the occlusal mandibular angle; the intermaxillary angle (PP-PM) and the mandibular occlusal angle, posterior mandibular width on the disto-vestibular cusp, and the intermolar angle; and the OP-MP angle and mandibular occlusal angle and the posterior mandibular width on the disto-vestibular cusp. Conclusions: The mandibular arch form may be related to certain predisposing features in craniofacial morphology, such as jaw divergence, the Jarabak ratio, and the intermaxillary angle.

Treatment of Mandibular Impacted Canine in a Patient with Class II Division 1 Malocclusion with "Reverse Pin": A Case Report. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1774. [PMID: 37893493 PMCID: PMC10608428 DOI: 10.3390/medicina59101774] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/25/2023] [Accepted: 10/02/2023] [Indexed: 10/29/2023]
Abstract
This case report presents an orthodontic treatment conducted on a 13-year-old girl with bilateral Class II malocclusion and a mandibular impacted canine. The presence of an impacted tooth necessitates careful consideration of the timing of orthodontic treatment, the appropriate surgical procedure to expose the tooth, the specific orthodontic mechanics involved, and the potential problems that may arise, all of which depend on the type and location of the canine impaction in the jaw. The treatment plan included a surgical procedure to expose the impacted tooth and orthodontic traction to guide it into position. Correction of the Class II Division 1 malocclusion utilized a specialized technique called the "reverse pin", reducing vertical side effects. The revised version maintains clarity and key information about the case report and treatment.

Abstract
OBJECTIVE The Mandibular Advancement Device (MAD) is actually recommended for the treatment of Obstructive Sleep Apnea (OSA) with mild or moderate severity. The present study evaluated the effects of a fully customizable MAD-type device (It Makes You Sleep, IMYS), in patients with moderate-to-severe OSA. METHODS Twenty-nine patients (15 men and 14 women; mean age 62, SD ±10 years) were retrospectively enrolled. Home Sleep Apnea Testing ;(HSAT) was performed for all patients at baseline (T0) and after three months (T1) of IMYS therapy. The analyzed respiratory parameters were: Apnea-Hypopnea Index (AHI), Oxygen Desaturation Index (ODI), Minimum Oxygen Saturation (minSO2) and Medium Oxygen Saturation (medSO2). RESULTS From T0 to T1, a significant reduction of AHI and ODI was reported, as well as a significant increase of minSO2 and medSO2. CONCLUSION The IMYS device could be an effective MAD appliance for treating moderate-to-severe OSA.

Abstract
The evolution of medical knowledge about oral microbiota has increased awareness of its important role for the entire human body health. A wide range of microbial species colonizing the oral cavity interact both with each other and with their host through complex pathways. Usually, these interactions lead to a harmonious coexistence (i.e. eubiosis). However, several factors - including diet, poor oral hygiene, tobacco smoking, and certain medications, among others - can disrupt this weak homeostatic balance (i.e. dysbiosis) with potential implications on both oral (i.e. development of caries and periodontal disease) and systemic health. This article is thus aimed at providing an overview on the importance of oral microbiota in mediating several physiological and pathological conditions affecting human health. In this context, strategies based on oral hygiene and diet as well as the role of probiotics supplementation are discussed.

Oral bisphosphonate-induced osteonecrosis complications in patients undergoing tooth extraction: a systematic review and literature updates. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2023; 27:6359-6373.

Abstract
OBJECTIVE Bisphosphonates, the most common anti-resorptive medications, are internalized by osteoclasts, where they inhibit the macrophage colony-stimulating factor (M-CSF) pathway, preventing their differentiation, inhibiting anchorage to the cell membrane, and inducing apoptosis. In patients undergoing oral bisphosphonate therapy, oral surgery involves a high risk of developing drug-related osteonecrosis of the jaws (BRONJ/MRONJ), among the possible complications. MATERIALS AND METHODS A systematic search was carried out on the PubMed, Scopus and Cochrane Library search engines, using the keywords "oral bisphosphonates AND tooth extraction", "third molar extraction AND oral bisphosphonates". In addition, we manually evaluated the articles included in references from other sources and an analysis of the Gray Literature was performed. A secondary outcome was to evaluate the assessment of pharmacological (antibiotics) use in the BRONJ/MRONJ management. The revision protocol followed the indications of the Cochrane Handbook, and was registered in the INPLASY database, while the drafting of the manuscript was based on PRISMA. RESULTS The results of the systematic review, after the study identification and selection process, included a total of 7 studies: 4 retrospective studies, 2 prospective studies and 1 case report. The main complication was represented by osteonecrosis of the jaws, which appears to be related to the duration of treatment with bisphosphonates; in addition, data regarding the anatomical location of post-extraction sites, the sex and age of patients, comorbidities and various systemic risk factors were extrapolated. The most frequent post-extraction complication in patients treated with oral bisphosphonates is osteonecrosis of the jaws, with a significant prevalence in the posterior region of the mandible. In some cases, delayed healing of the surgical wound was also found; moreover, the duration of exposure to oral bisphosphonates influences the onset of complications. CONCLUSIONS Ongoing studies continue to unravel the role of the oral environment response in alveolar bone homeostasis and how it might contribute to the induction of BRONJ/MRONJ. Approaching the problem from this perspective could provide new directions for the prevention of BRONJ/MRONJ and expand our understanding of the unique oral microenvironment.

Abstract
A large percentage of coronavirus disease 2019 (COVID-19) patients have taste dysfunction. Interleukin 6 (IL-6) levels in mild and moderate COVID-19 patients with the type (quantitative or qualitative) of taste disorders were compared in this observational study. The 208 COVID-19 patients (118 men and 90 women) revealing only taste dysfunctions as prodromic symptoms were classified as mild and moderate patients. Survey results were used to evaluate the taste disorder. The IL-6 levels were measured using a chemiluminescence assay. Statistical analysis was conducted using the Wilcoxon rank, Welch's, and Mann-Whitney tests. The findings revealed that neither the presence of dysgeusia or phantogeusia nor the perception of sour and salty, differed statistically significantly between moderate and mild patients (P > 0.05). But between moderate and mild patients, there were statistically significant differences in how umami, bitter, sweet, and parageusia were perceived (P < 0.05). There was an impairment of multiple tastes up to ageusia in patients with high IL-6 levels. The findings demonstrated that parageusia and dysfunctions in umami, bitter, and sweet taste perception can be indicators of more severe forms of COVID-19.

Abstract
OBJECTIVE AND DESIGN The aim of this study was to relate IL-6 and IL-1β serum levels with the severity of olfactory disorders and with the type of unperceived odors. MATERIALS AND METHODS 82 inpatients (45 men aged 62.3 ±14.2 and 37 women aged 57.1± 12.8) with only smell dysfunctions were divided into two groups. The evaluation of the smell disorder was carried out with a questionnaire to define which sensitivity is most compromised in COVID-19 patients. Cytokine levels were measured with chemiluminescence and ELISA assay. Statistical analyses were performed with the Wilcoxon Rank test, Welch's Welch's T-test, and Mann-Whitney test (p <0.05). RESULTS Statistically significant differences in IL-6 and IL-1 β levels were found in moderate disease patients when there was an impairment of trigeminal sensitivity (p <0.05) and trigeminal and olfactory sensitivity. CONCLUSIONS The results obtained showed that in COVID-19 patients the impairment of trigeminal sensitivity in association with olfactory sensitivity was more prevalent in moderate than in mild forms.

Abstract
Abstract:
Oxidative stress is a major cellular and metabolic burden that can really alter cell life and become the base for disease onset and development. Many widespread pathologies can develop from an unresolved oxidative stress situation; thus, addressing this state is paramount for human health. Our antioxidant enzymes sometimes are not just enough. Fortifying our defense and the antioxidant and anti-inflammatory system can make a difference in our health: if this is attainable with our dietary habits, it could be a dream come true. Polyphenols are a fantastic tool indeed in the fight against oxidative stress: they are easy to obtain, with little cost, no side effects, and have a multitude of metabolic actions. This perspective review would shed light on polyphenol’s metabolic and molecular action regarding oxidative stress to help preserve our health.

Abstract
Congenital adrenal hyperplasia (CAH) is a genetic disorder characterized by an impairment of steroid synthesis due to an altered production of 21-hydroxylase enzyme. Corticoid hormones are involved in the development and functioning of many organs. The aim of the present study was to review the international literature to collect data regarding oral manifestations of CAH. A review of the literature describing oral features of patients affected by CAH was performed using electronic databases (PubMed and Scopus). The data about number of patients, form of CAH, and oral findings were extracted and analyzed. Seven studies were included in the final analysis. The principal findings reported regarded an advanced dental development observed in patients with CAH. One paper reported amelogenesis imperfecta and periodontal issues. The dentist could be the first specialist involved in the CAH syndrome diagnosis, identifying the characteristic features described above, especially for the classical simple virilizing and non-classical form.

Abstract
BACKGROUND: Rosalind Franklin was a British scientist in the 1950s, that in her short career covered a lot of important scientific topics, ranging from coal structure porosity, to biological molecules cristallography, and finally to viruses structure definition.
AIM: This article aimed to underline the important role that she had for the elucidation of the DNA structure, and to reiterate the difficulties, she had to face – prominently as a woman – to be fully accepted in the world of scientific research.
METHODS: An historical research was conducted and summarized, regarding the life of Rosalind Franklin.
RESULTS: This myth overshadowed her intellectual strength and independence both as a scientist and as an individual.
CONCLUSION: As one of the twentieth century’s pre-eminent scientists, Franklin’s work has benefited all of humanity. The 100th anniversary of her birth in 2020 was prompting much reflection on her career and research contributions, not least Franklin’s catalytic role in unraveling the structure of DNA Franklin’s premature death, combined with misogynist treatment by the male scientific establishment, cast her as a feminist icon.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers worldwide; in fact, it is among the top six neoplasms, with an incidence of about 370,000 new cases per year. The 5-year survival rate, despite chemotherapy, radiotherapy, and surgery for stages 3 and 4 of the disease, is low. MicroRNAs (miRNAs) are a large group of small single-stranded non-coding endogenous RNAs, approximately 18-25 nucleotides in length, that play a significant role in the post-transcriptional regulation of genes. Recent studies investigated the tissue expression of miR-155 as a prognostic biomarker of survival in HNSCC. The purpose of this systematic review is, therefore, to investigate and summarize the current findings in the literature concerning the potential prognostic expression of tissue miR-155 in patients with HNSCC. The revision was performed according to PRISMA indications: three databases (PubMed, Scopus, and the Cochrane Register) were consulted through the use of keywords relevant to the revision topic. Totally, eight studies were included and meta-analyzed. The main results report for the aggregate HR values of 1.40 for OS, 1.36 for DFS, and 1.09 for DPS. Finally, a trial sequencing analysis was also conducted to test the robustness of the proposed meta-analysis.

Abstract
Oral carcinoma represents one of the main carcinomas of the head and neck region, with a 5-year survival rate of less than 50%. Smoking and tobacco use are recognized risk factors. Prognostic survival biomarkers can be a valid tool for assessing a patient’s life expectancy and directing therapy towards specific targets. Among the biomarkers, the alteration of miR-21 expression in tumor tissues is increasingly reported as a valid prognostic biomarker of survival for oral cancer. The purpose of this meta-analysis was, therefore, to investigate and summarize the results in the literature concerning the potential prognostic expression of tissue miR-21 in patients with OSCC. Methods: The systematic review was conducted following the PRISMA guidelines using electronic databases, such as PubMed, Scopus, and the Cochrane Central Register of Controlled Trials, with the use of combinations of keywords, such as miR-21 AND oral cancer, microRNA AND oral cancer, and miR-21. The meta-analysis was performed using the RevMan 5.41 software. Results: At the end of the article-selection process, 10 studies were included in the meta-analysis, and the result for the main outcome was a pooled HR per overall survival (OS) of 1.29 (1.16–1.44) between high and low expression of miR-21. Conclusions: The data in the literature and the results emerging from the systematic review indicate that miR-21 can provide a prognostic indication in oral cancer.

Abstract
BACKGROUND: Chronic rhinosinusitis (CRS) is a common condition that is defined as inflammation of the nose and paranasal sinuses. Nasal irrigation plays an important role in the treatment of CRS. Evidence from basic research favors hypertonic saline over isotonic saline for mucociliary clearance, but evidence from clinical studies is controversial.
AIM: This study aims to investigate the hypothesis that the use of daily nasal irrigation based on sea salt, enriched with natural enzymes and lysozyme, may be useful in patients with CRS.
PATIENT AND METHODS: Patients (30 men and 30 women) 18–55 years old (mean age 41 ± 3 y.o.), with two episodes of acute sinusitis or one episode of chronic sinusitis per year for 2 consecutive years, were enrolled stratified by sex and age and randomly divided into two groups supplementation: Group A (test) and Group B (control/placebo). Moreover, an exit questionnaire was asked to Group A subjects to report whether their sinus-related quality of life has gotten worse, stayed the same, or improved (scale from 0 to ±100%).
RESULTS: The result showed that in the test group (A) from T0 to T1, a reduction of 17.65% for the symptoms related headache and/or facial pressure and a reduction of the 18.18%, for the symptoms relates to congestion and/or nasal discharge. On the other hand, the control group (B) shown less difference between T0 and T1.
CONCLUSIONS: This study strengthens the argument that the tested formulation is a safe, well-tolerated, long-term therapy that patients with chronic sinonasal complaints can and will use at home with minimal training and follow-up.

Abstract
BACKGROUND The measurement of Fibroblast growth factor 23 (FGF23) may be useful in the diagnosis and management of abnormal phosphate metabolism in both patients with preserved renal function or with chronic kidney disease (CKD). FGF-23 tests differ considerably by molecule assayed (iFGF23 or cFGF23), analytical performance and reference ranges. We establish iFGF23 Upper Reference Limits (URL) in apparently healthy pediatric individuals using automated immunochemiluminescent assay. METHODS We measured the levels of plasma iFGF23 from 115 samples from apparently healthy pediatric subjects [59 (51.3%) individuals were male; median age 10 years (range 1-18)] included in an observational study conducted at Policlinico University Hospital of Bari. The method used for the iFGF23 assay was immunochemiluminescent sandwich assay developed by DiaSorin on the Liaison XL platform. Statistical calculation of 95% reference interval, right-sided (CLSI C28-A3) and verification of age and sex covariables was performed for the calculation of the URL. RESULTS The URL concentration of iFGF23 was 61.21 pg/mL (58.63 to 63.71, 90% CI). No significant differences were found between the median concentrations of iFGF23 differentiated by sex and age. CONCLUSIONS The dosage of iFGF23 is important both for the differential diagnosis of the various forms of rickets, and for the subsequent monitoring of the effectiveness of drug treatment. We have established the URL for the iFGF23 Liaison test in apparently healthy pediatric subjects. The availability of iFGF23 pediatric reference values will allow a better clinical use of the test.

Twenty Class II patients treated using the EA (Group EA) were compared with 20 Class II untreated children (Group C). Cephalograms were compared at the start (T0) and after 24 months (T1) after which time, skeletal, dental, and aesthetic variables were evaluated. A statistical evaluation was conducted by applying an unpaired t-test for normally distributed variables.
Results
From T0 to T1, the EA group showed a significant increase in lower facial height (LFH), in mandibular length (Co-Gn), in the upper incisor and cranial plane angle (1 + SN) and in the distance between a true vertical line (TVL)-soft tissue B (B’) and TVL-soft tissue Pogonion (Pog’) points. From T0 to T1, group C showed a significant decrease in SN-occlusal plane (PO) (p < 0.01), of SN-mandibular plane (Go-Me) (p < 0.01) and of total gonial (N-Go-Me) angles (p < 0.05); a significant reduction of the distance between TVL-upper incisor (1+), TVL-lower lip (Li), and TVL-Pog’ was shown. No statistical differences were observed between the groups in dental and aesthetic outcomes, except for a skeletal increase in LFH (p < 0.05) and in Co-Gn length (p < 0.05), which was statistically significant in the EA group.
Conclusion
In Class II growing patients, the EA induces minor skeletal effects, compared to untreated control patients.

Prosthetic rehabilitation of maxillary lateral incisors agenesis using dental mini-implants: a multicenter 10-year follow-up. Clin Oral Investig 2021; 26:1963-1974. [PMID: 34564740 PMCID: PMC8816522 DOI: 10.1007/s00784-021-04176-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2020] [Accepted: 09/01/2021] [Indexed: 11/28/2022]
Abstract
Objectives Implants are used to replace congenitally missing lateral incisors but often the space across the alveolar crest is too narrow to permit their use. This multicenter study (Dental Clinic of the University of Foggia, Odontostomatology Clinic of the University of L’Aquila) evaluated the efficacy of mini-implants in cases of maxillary lateral incisor agenesis with severe osseous atrophy in 10-year follow-up. Materials and methods Forty-seven mini-implants have been inserted in 35 patients affected by lateral incisors agenesis (23 single and 12 bilateral ageneses). All patients underwent orthodontic opening of the space of the upper lateral incisors. After the insertion of the implants, the immediate, non-functional loading, positioning of crowns, presence of pain during percussion and mini-implant function, horizontal and vertical movement when a force of 5 N was applied, ridge loss, and plaque index have been evaluated 1 month after loading, 1 year after loading, and then every 5 years in the following 10 years. Little’s test was used to evaluate the assumption that data of loss to follow-up implants are missing completely at random (MCAR) and that a complete-case scenario could be adopted. Wilcoxon test was carried out to look statistically significant differences between the various parameters resulting in the complete-case scenario and those assumed for the worst scenario. The software R (v. 3.6.1, 2019) was employed to perform the statistical analysis. Results The results obtained over 10 years range from 89% of success rate in a worst-case scenario to the 100% using a complete-case analysis with satisfactory values of marginal bone resorption and good conditions of the peri-implant tissue. Ten-year follow-up using complete-case analysis shows survival rates of 100% for implants with no signs of peri-implantitis, stability of the marginal bone levels and soft tissue around the dental implants. Conclusions The data collected show very good implant stability, absence of progressive peri-implantitis, and satisfactory aesthetical results in time (no signs of infraocclusion). Clinical relevance Mini-implants can be considered a valid and stable over time solution in the restorative treatment of maxillary lateral incisors agenesis.

Autotransplantation of the Third Molar: A Therapeutic Alternative to the Rehabilitation of a Missing Tooth: A Scoping Review. Bioengineering (Basel) 2021; 8:120. [PMID: 34562942 PMCID: PMC8468762 DOI: 10.3390/bioengineering8090120] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 08/28/2021] [Accepted: 08/30/2021] [Indexed: 12/17/2022] Open
Abstract
INTRODUCTION Tooth autotransplantation is the repositioning of an erupted, partially erupted, or non-erupted autologous tooth from one site to another within the same individual. Several factors influence the success rate of the autotransplant, such as the stage of root development, the morphology of the tooth, the surgical procedure selected, the extraoral time, the shape of the recipient socket, the vascularity of the recipient bed, and the vitality of the cells of the periodontal ligament. The aim of this scoping review was to provide the most up-to-date information and data on the clinical principles of the third-molar autograft and thus provide clinical considerations for its success. MATERIALS AND METHODS This review was conducted based on PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews). The research was conducted by searching for keywords in three databases-PubMed, Scopus and Google Scholar-by two independent reviewers following the PRISMA protocol, from which 599 records were identified. CONCLUSIONS Third-molar autotransplantation is a valid solution to replace missing teeth. The key to the success of this technique is the surgical procedure, which must be as atraumatic as possible to preserve the periodontal ligament of the tooth to be transplanted. The success rate is also linked to the stage of development of the root, with a worse prognosis in the case of a complete root.

Sealing ability and microbial leakage of root-end filling materials: MTA versus epoxy resin: A systematic review and meta-analysis. Heliyon 2021; 7:e07494. [PMID: 34401555 PMCID: PMC8353296 DOI: 10.1016/j.heliyon.2021.e07494] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Revised: 05/27/2021] [Accepted: 07/02/2021] [Indexed: 01/30/2023] Open
Abstract
Objectives The purpose of this systematic review of the literature is to investigate which of the epoxy-based cements and those based on Tricalciumsilicate (MTA, Bioceramic) have the best sealing capacity through the analysis of studies that have provided a survey model in vitro of bacteria leakage. Source The articles were identified using electronic databases such as PubMed, Scopus, the search was conducted between 8.12.2020 and 31.12.2020 and a last search was conducted on 2.12.2021. Study selection 678 records were identified and after removing the duplicates we obtain 481 records, with the first phase of screening and selection of records we reached 204 and with the application of the inclusion and exclusion criteria we selected 31 articles, only 9 studies made a direct comparison between the two endodontic cement categories and presented data that could be included in the metaanalysis. Data The meta-analysis of first outcome shows an odds ratio of 2.70 C.I.(Confidence Interval) [1.54, 4.73], the test for overall effect has a p value = 0.0005 with a heterogeneity index of I 2 of 9%; The second outcome meta-analysis shows an Odds Ratio of 1.50 C.I. (Confidence Interval) [0.92, 2.46] with a p value of 0.10 with an I 2 of 79%. Conclusion the sealing ability is higher for epoxy resins than for tricalcium silicate-based cements, for observation periods longer than 90 days. Clinical relevance The knowledge of the cement that determines the best sealing ability and resistance to microbial leakage, can be of help for the dentist who has to face clinical situations such as endodontic retreatments whose failure is determined by the persistence of bacteria in the endodontic canals.

Abstract
Objective: This is a rapid systematic review concerning taste alterations in 27,687 individuals infected with SARS-CoV-2, published in the worldwide literature.Material and methods: Of the 485 articles recovered, 67 eligible studies (27,687 confirmed COVID-19 cases) were included in this analysis. We analysed the prevalence of the taste alterations in patients considering the country of origin of the studies.Results: The results show strong important differences in the overall reported prevalence of taste alterations among the different countries (from 11% of Korea to 88.8% of Belgium).Conclusions: These data highlight that there is a different geographical distribution of taste alterations in COVID-19 patients. Gustatory dysfunction seems to be an understudied symptom of COVID-19 and this may explain the inconsistencies of diagnostic criteria for COVID-19 case definition. Furthermore, this diagnostic underestimation can lead to an increased risk of contagion for the whole population and for the working classes most at risk, including the dental one.

Abstract
The aim of the present investigation was to evaluate the essential physiological functions of the skin microbiota in human health and diseases. The main characteristics of the normal microbiota in the different anatomical sites have been reported in relation to the main factors, such as the effect of age, on its composition and stability for the eubiosis condition. Moreover, the present overview analyzed the functions and composition and the correct functionality of the skin microbiota in the light of current knowledge. According to several evidence is important preserving the eubiosis of the commensal microbes of the microecosystem (symbiotic and pathogenic), and probiotics are able to counteract the conditions of dysbiosis. Also, it has been shown that there is a crosstalk between gut and skin microbiota that affects human health and is still being studied, and its relationship to the current pandemic SARS-CoV-2.

Abstract
COVID-19 (Coronavirus Disease 2019) is an emerging viral disease caused by the coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), which leads to severe respiratory infections in humans. The first reports came in December 2019 from the city of Wuhan in the province of Hubei in China. It was immediately clear that children developed a milder disease than adults. The reasons for the milder course of the disease were attributed to several factors: innate immunity, difference in ACE2 (angiotensin-converting enzyme II) receptor expression, and previous infections with other common coronaviruses (CovH). This literature review aims to summarize aspects of innate immunity by focusing on the role of ACE2 expression and viral infections in children in modulating the antibody response to SARS-CoV-2 infection. This review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles deemed potentially eligible were considered, including those dealing with COVID-19 in children and providing more up-to-date and significant data in terms of epidemiology, prognosis, course, and symptoms, focusing on the etiopathogenesis of SARS-CoV-2 disease in children. The bibliographic search was conducted using the search engines PubMed and Scopus. The following search terms were entered in PubMed and Scopus: COVID-19 AND ACE2 AND Children; COVID-19 AND Immunity innate AND children. The search identified 857 records, and 18 studies were applicable based on inclusion and exclusion criteria that addressed the issues of COVID-19 concerning the role of ACE2 expression in children. The scientific literature agrees that children develop milder COVID-19 disease than adults. Milder symptomatology could be attributed to innate immunity or previous CovH virus infections, while it is not yet fully understood how the differential expression of ACE2 in children could contribute to milder disease.

Abstract
Current medical knowledge and research on patients’ management are still evolving, and several protocols on minimizing risk of infection by Candida spp. among the population have developed. The aim of this work is to review the epidemiological and biomolecular characteristics and the various histopathological carcinogenesis hypothesis mechanisms that can occur during Candida albicans infections. Current evidence from the literature on the role of C. albicans during potentially malignant oral disorders and oral cancer has been sought. Thus, these biomolecular processes can give or contribute to benign lesions, also in precancerous or cancerous situations. Alongside this, the physiological microorganism oral flora (microbiota) can play a crucial role in maintaining oral health during those infections and therefore avoid carcinogenesis.

Determination of the Upper Reference Limit of Human Epididymis Secretory Protein 4 (HE4) in Healthy Male Individuals and Correlation with Renal and Fertility Markers. Endocr Metab Immune Disord Drug Targets 2021; 21:912-918. [PMID: 32767951 DOI: 10.2174/1871530320666200807121050] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 06/05/2020] [Accepted: 06/08/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Elevated human epididymis secretory protein 4 (HE4) serum levels have been widely investigated in patients with ovarian cancer. However, high levels of HE4 can be also found in other tumors and in renal fibrosis. To date, the HE4 assay manufacturer features the reference value only for the female pre- and post-menopausal population. The aim of this study was to determine the upper reference limit (URL) of HE4 in a well-defined and large cohort of healthy male individuals and investigate potential factors influencing HE4 levels in healthy subjects. METHODS The study included 307 Italian healthy male individuals. HE4 was measured using a chemiluminescent assay (Abbott Laboratories, Wiesbaden, Germany). The URL was calculated using the non-parametric percentile method. Differences in HE4 concentrations according to age, estimated glomerular filtration rate (eGFR), free and bioavailable testosterone were also evaluated. RESULTS The 97.5th percentile URL of serum HE4 in our study population was 57 pmol/L (90% CI). After stratifying subjects according to age, we found that the URL of HE4 was higher in older (> 50 years) than in younger subjects (18-30 years old), and overlapping with the URL in males from 31 to 50 years old (P=4.769e-16, r=0.44). A strong negative correlation between HE4 and eGFR was observed (P=8.412e-12, r=-0.38). Moreover, a statistically significant negative correlation was also found between HE4 and free and bioavailable testosterone. CONCLUSION This study determined the URL of HE4 in a large cohort of healthy male subjects. Our findings indicate that the HE4 age-dependent differences in males need to be taken into account. The definition of the HE4 URL in males and the correlation observed with eGFR and testosterone should foster the clinical use of HE4 beyond gynecologic cancer.

The Effects of Sterilization Procedures on the Cutting Efficiency of Endodontic Instruments: A Systematic Review and Network Meta-Analysis. MATERIALS 2021; 14:ma14061559.

Abstract
Sterilization processes guarantee the sterility of dental instruments but can negatively affect instrument features by altering their physical and mechanical properties. The endodontic instrumentation can undergo a series of alterations, ranging from corrosion to variation in the cutting angle and then changes in the torsional properties and torsional fatigue resistance. This systematic literature review and meta-analysis aims to investigate alterations to the cutting efficiency of endodontic instruments that are induced by procedures for their disinfection and sterilization. Methodologies adopted for this investigation follow the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. The following were used as search terms on PubMed and Scopus: "endodontic sterilization", "endodontic autoclave", "cyclic fatigue", "torsional", "cutting efficiency", "sterilization", "surface characteristics", and "corrosion". At the end of the selection process, 36 articles were identified, and seven of them are included in this systematic review. The results of a meta-analysis conducted for the use of 10 autoclaving cycles shows a standardized mean difference (SMD) of 0.80 with a p-value equal to 0.04 with respect to effect on cutting efficiency. The network meta-analysis, through direct and indirect comparison between the different autoclave cycles (0, 1, 5, 10, and 15 cycles), revealed that treatment involving 15 autoclave cycles produced the most robust results in terms of having the greatest effects in terms of altered cutting efficiency with a probability of 57.7% and a SUCRA (surface under the cumulative ranking) of 80%. The alterations in the effects on cutting efficiency appear to be triggered after five cycles of sterilization by heat (autoclave). In conclusion, the meta-analysis of the data indicates that the autoclave sterilization protocol must not be repeated more than five times to preserve cutting efficiency. Within the limitations of this review, we can therefore establish that sterilization by autoclaving alone results in steel and NiTi instruments becoming less efficient in cutting after five cycles, as measured by a reduction in cutting efficiency.

Abstract
Aim: Inflammatory idiopathic myopathies (IIMs) are inflammatory processes affecting skeletal musculature and extramuscular organs. Temporomandibular disorders (TMD) involve jaw muscles and temporomandibular joint. The aim of this observational study was to investigate the prevalence of the main TMD symptoms and signs as well as oral implications in IIM patients. Methods: The study group included 54 patients (42 women and 12 men), 22 of whom affected by dermatomyositis (DM), 29 by polymyositis (PM) and 3 by inclusion body myositis (IBM). A group of 54 patients not affected by this disease, served as CG. Oral and TMD signs and symptoms were evaluated by means of a questionnaire and through clinical examination. Results: About oral symptoms, the study group complained more frequently dysgeusia, with loss of taste or unpleasant taste (p<0.0001) and feeling of burning mouth (9.4% versus 0 controls). Xerostomia was more prevalent in the study group respect to the CG (p<0.0001). Dysphagia was reported by 48.1% of IIM patients while was absent in CG (p<0.0001). About oral signs, cheilitis (p<0.05) and oral ulcers (p<0.05) were significantly more frequent in CG. As regard to TMD symptoms, arthralgia and tinnitus didn't showed significant differences between the two groups, while neck/shoulders and masticatory muscle pain was significantly more referred in IIM patients than in the CG (p<0.05). About TMJ signs, sounds were overlapping in the two groups: click=11.1% in both IIM patients and CG (p>0.05), crepitation in 11.1% of IIM and 9.3% of controls (p>0.05). No significant difference was detected about deflection (9.3%, p>0.05), while deviation was wider in CG (p<0.05). Active opening and lateralities showed no significant differences, while endfeel was significantly increased in IIM group for a higher presence of muscular contracture. Bruxism was present only in CG. Conclusion: The data collected from this observational study seem to support the existence of a relationship between the prevalence of TMD symptoms and signs as well as oral features in patients with myositis. A remarkable reduction of salivary flow and dysphagia were more frequent and severe in IIM patients, as well as muscle contracture and myofacial pain evoked by palpation, this result being highly significant.

New Insights in Laboratory Testing for COVID-19 Patients: Looking for the Role and Predictive Value of Human epididymis secretory protein 4 (HE4) and the Innate Immunity of the Oral Cavity and Respiratory Tract. Microorganisms 2020; 8:E1718. [PMID: 33147871 PMCID: PMC7692217 DOI: 10.3390/microorganisms8111718] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 10/23/2020] [Accepted: 10/30/2020] [Indexed: 12/15/2022] Open
Abstract
COVID-19 is a viral pandemic caused by the new coronavirus SARS-CoV-2, an enveloped positive stranded RNA virus. The mechanisms of innate immunity, considered as the first line of antiviral defense, is essential towards viruses. A significant role in host defense of the lung, nasal and oral cavities is played by Human epididymis secretory protein 4 (HE4) HE4 has been demonstrated to be serum inflammatory biomarker and to show a role in natural immunity at the level of oral cavity, nasopharynx and respiratory tract with both antimicrobial/antiviral and anti-inflammatory activity. Several biomarkers like IL-6, presepsin (PSP), procalcitonin (PCT), CRP, D-Dimer have showed a good function as predictor factors for the clinical evolution of COVID-19 patients (mild, severe and critical). The aim of this study was to correlate the blood levels of CRP, IL-6, PSP, PCT, D-Dimer with He4, to identify the predictive values of these biomarkers for the evolution of the disease and to evaluate the possible role of HE4 in the defense mechanisms of innate immunity at the level of oral cavity, nasopharynx and respiratory tract. Of 134 patients admitted at COVID hospital of Policlinico-University of Bari, 86 (58 men age 67.6 ± 12.4 and 28 women age 65.7 ± 15.4) fulfilled the inclusion criteria: in particular, 80 patients (93%) showed prodromal symptoms (smell and/or taste dysfunctions) and other typical clinical manifestations and 19 died (13 men age 73.4 ± 7.7 and 6 women age 74.8 ± 6.7). 48 patients were excluded because 13 finished chemotherapy and 6 radiotherapy recently, 5 presented suspected breast carcinoma, 5 suspected lung carcinoma, 6 suspected ovarian carcinoma or ovary cyst, 1 cystic fibrosis, 3 renal fibrosis and 9 were affected by autoimmune diseases in treatment with monoclonal antibodies. The venous sample was taken for each patient on the admission and during the hospital stay. For each patient, six measurements relating to considered parameters were performed. Significant correlations between He4 and IL-6 levels (r = 0.797), between He4 and PSP (r = 0.621), between He4 and PCT (r = 0.447), between He4 and D-Dimer (r = 0.367), between He4 and RCP (r = 0.327) have been found. ROC curves analysis showed an excellent accuracy for He4 (AUC = 0.92) and IL-6 (AUC = 0.91), a very good accuracy for PSP (AUC = 0.81), a good accuracy for PCT (AUC = 0.701) and D-Dimer (AUC = 0.721) and sufficient accuracy for RCP (AUC = 0.616). These results demonstrated the important correlation between He4, IL6 and PSP, an excellent accuracy of He4 and IL6 and showed a probable role of He4 in the innate immunity in particularly at the level of oral cavity, nasopharynx and respiratory tract. Besides He4 together with IL6 might be involved in the onset of smell and/or taste disorders and it might be used as innovative biomarker to monitor clinical evolution of COVID-19 because He4 could indicate a multi-organ involvement.

Abstract
Background Mandibular condylar fractures commonly occur after trauma and account for 25 to 35% of all mandibular fractures; its appropriate therapy still remains a point of controversy in children. The purpose of this paper is to describe the treatment of an 11-years-old male patient affected by neck-condylar fracture as result of trauma in evolutive age. Methods No surgical treatment was performed. A functional therapy was applied with a jaw splint. A closed treatment for mandibular condyle fractures was preferred because the amount of condylar displacement wasn’t considerable. Results The early treatment with functional therapy generated a functional adaptation of the condyle in the glenoid fossa and a normal mandibular function. After a 12-month follow-up the fracture resolution and an optimal condylar position were recorded. Conclusions The current case report and literature review showed that non-surgical therapy of neck-condylar fracture in a child with lower resin splint can restore mandibular movements and aesthetics.

Abstract
White spot lesions are defined as enamel surface and sub surface demineralisation, although these lesions can be reversed and do not form cavities. Infiltration using fluid resin proved to be a valid micro-invasive alternative compared with traditional conservative therapy. This has allowed treatment without any trauma (no use of local anaesthesia and cavity preparation) of numerous lesions in only one session with stable clinical (mechanical stability, enamel hardness, conservation of sound tissue) and aesthetic results (disappearance of lesions) over the time. The present report evaluates the effectiveness of Icon infiltration resin on postorthodontic white spots at 6 months, 1 and 4 years.

Abstract
BACKGROUND Odontomas are the most common benign odontogenic tumors (especially in children and adolescents) and consist of odontogenic ectomesenchyma and odontogenic epithelium with the formation of dental hard tissues. They are also simply considered hamartomas. The WHO Classification defines them as complex and compound odontomas. The diagnosis is often occasional, in conjunction with x-ray routine examinations, or it is suggested by eruption disorders or abnormal position of teeth in the dental arch. The mainstay therapy is surgical excision of the lesion followed by orthodontic treatment to take in the arch the impacted teeth. CASE REPORT The aim of this work is the presentation of a case of mandibular bilateral compound odontoma in a young patient, and the confocal laser scanning microscopic analysis of the surgical specimens.

Abstract
Background Langerhans cell histiocytosis is a sporadic disease caused by an uncontrolled pathogenic clonal proliferation of dendritic cells that have Langerhans cell characteristics. New treatment protocols provided by the HISTSOC-LCH-III (NCT00276757) trial show an improvement in the survival of children with langerhans cell histiocytosis. Case presentation We report a case of Langerhans cell histiocytosis, which presented as an osteolytic lesion of the left pre-maxillae enclosing the deciduous incisor and canine in a 7-month-old white Italian boy. He was treated with chemotherapy. He achieved complete remission after 7 months and after 24 months no signs of recurrence were observed. Conclusions As a result of this treatment, anesthetic sequelae and loss of teeth were avoided; in addition, we prevented a loss of the vertical dimension of occlusion.

Abstract
BACKGROUND Hyperphosphatemic familial tumoral calcinosis (HFTC) is to a rare autosomal recessive disorder characterized by cutaneous and sub-cutaneous calcified masses, usually adjacent to large joints. The aim of the current study was to report on the clinico-pathological features of a patient with HFCT, with emphasis on alterations in the jawbones and teeth and the subsequent therapeutic interventions. CASE REPORT A 13-year-old male patient with HFTC diagnosis came to our attention for dental anomalies and maxillary and mandibular hypoplasia. OPT highlighted multiple impacted teeth, short and bulbous teeth, and pulp chamber and canal obliterations. Lateral cephalometric radiograms pointed out retrusion of both jaws, skeletal class II malocclusion, and deep-bite. He underwent orthopedic, orthodontic, conservative, and surgical treatments, allowing the correction of maxillo-facial and dental abnormalities and dysmorphisms without adverse effects. The surgical samples were sent for conventional and confocal laser scanning microscope (CLSM) histopathological examination, which highlighted several metaplastic micro- and macro-calcifications in the soft tissues, and typical islands of homogenous, non-tubular, dentino-osteoid calcified structures in dentinal tissues. CONCLUSIONS The management of maxillo-facial abnormalities in patients affected by HFTC is very difficult and, requires a combined therapeutic approach. To date, very few indications have been published in the literature.

Abstract
AIM Our objective was to investigate the occurrence of sleep-related breathing disturbances in a large cohort of school-aged children in Southern Italy, and to evaluate the association with anthropometric data and clinical findings of oropharynx and nasal airways. STUDY DESIGN A two-phase cross-sectional study was conducted with children from schools in Turi, Italy. MATERIALS AND METHODS A screening phase aimed to identify symptomatic children and clinical data from a cohort of 495 children by a self-administered questionnaire, and an instrumental phase for the definition of sleep-related disorders and clinical analysis of oral status were performed. According to the answers, children were classified into 3 groups: habitual snorers, occasional snorers, and non-snorers. All habitual snoring children underwent a polysomnographic home evaluation, and those with oxygen desaturation index (ODI) > 2 were considered for nocturnal polygraphic monitoring (NPM). Children with apnoea/ hypopnea index (AHI) > 3 received a diagnosis of obstructive sleep apnoea syndrome (OSAS). Moreover, a complete oral examination was performed. RESULTS A total of 436 questionnaires (response rate: 88.08%) were returned and scored (202 M, 234 F; Mean age ± Standard deviation: 6.2 ± 1.8); 18 children (4%) were identified as habitual snorers, 140 children (32%) were identified as occasional snorers, and 278 children (64%) were identified as non-snorers. The percentage of female children who were habitual snorers was higher than the percentage of male children (4.7% vs 3.6%). Habitual snorers had significantly more nighttime symptoms. OSAS was diagnosed in 2 children by NPM. A statistically significant association between snoring, cross-bite, open-bite and increased over-jet was found. CONCLUSION Habitual snoring and OSAS are significant problems for children and may be associated with diurnal symptoms. The presence of malocclusion increases the likelihood of sleep-related breathing disturbances.

Abstract
AIM The aim of this study was to assess the correlation between osteogenesis imperfecta (OI) and dentinogenesis imperfecta (DI) from both a clinical and histological point of view, particularly clarifying the structural and ultrastructural dentine changes. DESIGN Sixteen children (6-12 years aged) with diagnosis of OI were examined for dental alterations referable to DI. For each patient, the OI type (I, III, or IV) was recorded. Extracted or normally exfoliated primary teeth were subjected to a histological examination (to both optical microscopy and confocal laser-scanning microscopy). RESULTS A total of ten patients had abnormal discolourations referable to DI: four patients were affected by OI type I, three patients by OI type III, and three patients by OI type IV. The discolourations, yellow/brown or opalescent grey, could not be related to the different types of OI. Histological exam of primary teeth showed severe pathological change in the dentin, structured into four different layers. A collagen defect due to odontoblast dysfunction was theorized to be on the base of the histological changes. CONCLUSIONS There is no correlation between the type of OI and the type of discolouration. The underlying dentinal defect seems to be related to an odontoblast dysfunction.

A novel mutation of gene CBFA1/RUNX2 in cleidocranial dysplasia. ANNALS OF CLINICAL AND LABORATORY SCIENCE 2007; 37:115-20.

Abstract
Cleidocranial dysplasia (CCD) is an autosomal dominant skeletal dysplasia characterised by abnormal clavicles, patent sutures and fontanelles, supernumerary teeth, short stature, and a variety of other skeletal changes. The disease gene is CBFA1/RUNX2, which is mapped to chromosome 6p21. Inactivation of the CBFA1/RUNX2 gene by mutations is involved in the skeletal defects that occur in patients with CCD. CBFA1/RUNX2 controls the differentiation of precursor cells into osteoblasts and is essential for membranous as well as endochondral bone formation. In this study of a 14-yr-old boy with typical CCD phenotype, the authors found a novel CBFA1/RUNX2 gene mutation. All of the amplified segments from the patient's CBFA1/RUNX2 gene were identical to those obtained in controls, except for the one spanning the exon 7 and intron/exon boundary regions. Direct sequencing of the PCR product showed a heterozygous T-to-A transition mutation at nucleotide 1182 in exon 7, leading to Y394X mutation. The predicted protein product lacks 128 amino acids, including part of the PST domain. Identification of this novel mutation constitutes a further step in elucidating the pathogenesis of this autosomal disorder.

Changes in pharyngeal aerobic microflora in oral breathers after palatal rapid expansion. BMC Oral Health 2006; 6:2.

Abstract
BACKGROUND The purpose of this study was to investigate in oral breathing children the qualitative and quantitative effects on aerobic and facultatively anaerobic oropharyngeal microflora of respiratory function improved by rapid palatal expansion (RPE). METHODS In an open clinical trial, we studied 50 oral breathers, aged 8 to 14 years and suffering from both maxillary constriction and posterior cross-bite. At baseline, patients were examined by a single otorhinolaryngologist (ENT), confirming nasal obstruction in all subjects by posterior rhino-manometric test. Patients were evaluated three times by oropharyngeal swabs:1) at baseline (T = 0); 2) after palatal spreading out (T = 1); and 3) at the end of RPE treatment (T = 2). With regard to the microbiological aspect, the most common and potentially pathogenic oral microrganisms (i.e. Streptococcus pyogenes, Diplococcus pneumoniae, Staphylococcus aureus, Haemophilus spp, Branhamella catarrhalis, Klebsiella pneumoniae, Candida albicans) were specifically detected in proper culture plates, isolated colonies were identified by means of biochemical tests and counted by calibrated loop. The data were analyzed by means of the following tests: Chi-square test, Fisher's exact test and Wilcoxon's test. RESULTS After the use of RME there was a statistically significant decrease of Staphylococcus aureus stock at CFU/mLat T1(P = 0.0005; Z = -3,455 by Wilcoxon Rank test) and T2 (P < 0.0001; Z = -4,512 by Wilcoxon Rank test) vs T0. No significant changes were found for the other examined microrganisms. CONCLUSION Our data suggest that RPE therapy in oral breathers may strongly reduce the pathogenic aerobic and facultatively anaerobic microflora in the oral pharynx after a normalization of the upper airways function, and may reduce the risk of respiratory infections.
