RESUMO
Resveratrol is a polyphenol that has been shown to possess many applications in different fields of medicine. This systematic review has drawn attention to the axis between resveratrol and human microbiota, which plays a key role in maintaining an adequate immune response that can lead to different diseases when compromised. Resveratrol can also be an asset in new technologies, such as gene therapy. PubMed, Cochrane Library, Scopus, Web of Science, and Google Scholar were searched to find papers that matched our topic dating from 1 January 2017 up to 18 January 2022, with English-language restriction using the following Boolean keywords: ("resveratrol" AND "microbio*"). Eighteen studies were included as relevant papers matching the purpose of our investigation. Immune response, prevention of thrombotic complications, microbiota, gene therapy, and bone regeneration were retrieved as the main topics. The analyzed studies mostly involved resveratrol supplementation and its effects on human microbiota by trials in vitro, in vivo, and ex vivo. The beneficial activity of resveratrol is evident by analyzing the changes in the host's genetic expression and the gastrointestinal microbial community with its administration. The possibility of identifying individual microbial families may allow to tailor therapeutic plans with targeted polyphenolic diets when associated with microbial dysbiosis, such as inflammatory diseases of the gastrointestinal tract, degenerative diseases, tumors, obesity, diabetes, bone tissue regeneration, and metabolic syndrome.

Background: Cleidocranial dysplasia (CCD) is a rare, autosomal dominant skeletal dysplasia with a prevalence of one per million births. The main causes of CCD are mutations in the core-binding factor alpha-1 (CBFA1) or runt-related transcription factor-2 (RUNX2), located at the 6p21 chromosomal region. RUNX2 plays important roles in osteoblast differentiation, chondrocyte proliferation and differentiation, and tooth formation. The disease is characterized by clavicular aplasia or hypoplasia, Wormian bones, delayed closure of cranial suture, brachycephalic head, maxillary deficiency, retention of primary teeth, inclusion of permanent teeth, and multiple supernumerary teeth. Materials and Methods: A 22-year-old girl suffering from cleidocranial dysplasia with short stature, narrow shoulders, craniofacial manifestations (short face, broad forehead, etc.) and dental anomalies (different lower dental elements under eruption, supernumerary and impacted multiple teeth, etc.) was examined at our service (Complex Operative Unit of Odontostomatology of Policlinico of Bari). RX Orthopantomography (OPG) and cone beam computed tomography (CBCT) were requested to better assess the position of the supernumerary teeth and their relationships with others and to evaluate the bone tissue. Results: Under eruption was probably caused by dental interferences with supernumerary teeth; hence, extractions of supernumerary upper canines and lower premolars were performed under general anaesthesia. Surgery outcome was excellent with good tissue healing and improvements in the therapeutic possibilities with future orthodontics. Conclusions: The objective of this article is to give an update about radiological, clinical, and molecular features of CCD and to alert the health team about the importance of establishing an early diagnosis and an appropriate treatment in these patients to prevent impacted teeth complications and to offer them a better quality of life.

INTRODUCTION: Oral sex is usually considered a lower-risk sexual activity when compared with sex, but it is frequently the cause of sexually transmitted infections (STI). In particular, STI transferred through oral sex might have no visible symptoms, depending on the type of infection. AIMS: The aim of this study is to review the literature about the role of oral sex in the transmission of nonviral STI. MAIN OUTCOME MEASURES: State-of-the-art information in the area of STI in relation to sexual function and self-care, this last important for development of STI prevention products such as vaginal microbicides. Sexual behaviors assessed focusing on receiving oral sex and giving oral sex. METHODS: A search of the main electronic databases including registers of clinical controlled trials was performed in addition to a hand search of the most relevant Journals. The following electronic databases were searched: PubMed, Embase, Google Scholar, literature review of research articles, and public health department Internet Web sites, for the period of 1945-2011. In addition to searching the Clinical Trials Registry at the US National Institutes of Health, we also used the meta Register of Controlled Trials and the Cochrane Central Register of Controlled Trials. RESULTS: STI affect the mucous membranes both directly and indirectly producing characteristic diagnostic signs and lesions. Daily dental clinical activity needs an appropriate knowledge of any kind of oral lesions-related STI. The reader is offered a practical approach with clinically relevant recommendations that may prove useful in his/her daily practice when dealing with STI. CONCLUSIONS: These data provide a foundation for understanding diverse STI. We advise physicians to be receptive to discuss sexuality issues and provide patients with adequate therapy.

BACKGROUND: Elastodontics is a specific interceptive orthodontic treatment that uses removable elastomeric appliances. They are functional appliances that produce neuromuscular, orthopedic and dental effects. Thus, these devices are useful in the developmental age, when skeletal structures are characterized by important plasticity and adaptation capacity, allowing to remove factors responsible for malocclusions. Elastomeric devices are generally well tolerated by patients requiring simple collaboration and management. This work can be useful to update all orthodontists already adopting these appliances or for those who want to approach them for the first time. This study aimed to describe four cases treated with new elastomeric devices called AMCOP Bio-Activators and to provide an overview of elastodontics, its evolution, indications and limits. METHODS: A total of four clinical cases were presented after a treatment period of 16-20 months to evaluate the clinical and radiological effects of the elastodontic therapy. RESULTS: The effectiveness of Bio-Activators on clinical cases was evidenced with a significant improvement in skeletal and dentoalveolar relationship, and malocclusion correction in a limited treatment period (16-20 months). CONCLUSIONS: The Bio-Activators showed clinical effectiveness to achieve therapeutic targets according to a low impact on the patient's compliance.

INTRODUCTION: Several strategies have been proposed in the literature to accelerate tooth movement, many of which are invasive and have numerous side effects, such as surgical techniques (corticotomy and piezocision technique). This research investigates to what extent diathermy can accelerate the orthodontic alignment phase. MATERIALS AND METHODS: A patient with lower teeth crowding index of the same magnitude was selected. The orthodontic treatment with Nickel-Titanium (NiTi) thermal arc 0.015 in the lower arch was performed, associated with a weekly application of diathermy using the intraoral handpiece. The total duration of treatment was three weeks. During each session, an intraoral transducer was employed to stimulate the hard and soft tissues of the left dental hemiarch, which was also orthodontically aligned like the right one. RESULTS: Comparing the tooth movements of four elements of the two hemiarchies, it was found that, overall, the two teeth examined on the treated side underwent a more significant number of changes than on the untreated side, although not by a significant amount. CONCLUSIONS: The use of diathermy, according to the authors, is a non-invasive approach that may speed up the orthodontic alignment phase and reduce treatment duration, resulting in a lower risk of caries, gingival recessions, root resorptions, and patient compliance improvement, without side effects. Further studies and an adequate sample size will be needed to confirm the findings.

BACKGROUND: Cranial surface electromyography is assumed to analyze the correlation between the stomatognathic apparatus and the muscular system and its implications on the physical status of professional athletes. The purpose of this paper is to evaluate surface cranial electromyography as an aid in the diagnosis and treatment of occlusal and muscular disorders in professional athletes. METHODS: A sample of 25 athletes (mean age 23 years, 20 men and 5 women) underwent electromyographic recording; among them, 13 had a sports injury condition (symptomatic athletes), while 12 were in perfect physical condition (asymptomatic athletes). At odontostomatological examination, 6 showed cranio-mandibular disorders (dysfunctional athletes), while 19 showed no disorders (functional athletes). The treatment plan to resolve the symptoms of the dysfunctional athletes was chosen based on the electromyographic data. One month after the start of therapy with an occlusal splint, a follow-up was performed, and the results were compared with the initial data. RESULTS: Statistical analysis showed that the chosen therapy following the use of electromyography was effective in 72% of cases, while 28% of patients did not respond to therapy (p = 0.028). CONCLUSIONS: The use of cranial electromyography in competitive athletes is a valuable tool in therapeutic choice aimed at balancing occlusal loads and improving the patient's global tonic postural attitude, resulting in positive feedback in the qualitative assessment of sports performance.

Phenolic compounds are natural phytochemicals that have recently reported numerous health benefits. Resveratrol, curcumin, and quercetin have recently received the most attention among these molecules due to their documented antioxidant effects. The review aims to investigate the effects of these molecules on bone metabolism and their role in several diseases such as osteopenia and osteoporosis, bone tumours, and periodontitis. The PubMed/Medline, Web of Science, Google Scholar, Scopus, Cochrane Library, and Embase electronic databases were searched for papers in line with the study topic. According to an English language restriction, the screening period was from January 2012 to 3 July 2022, with the following Boolean keywords: ("resveratrol" AND "bone"); ("curcumin" AND "bone"); ("quercetin" AND "bone"). A total of 36 papers were identified as relevant to the purpose of our investigation. The studies reported the positive effects of the investigated phenolic compounds on bone metabolism and their potential application as adjuvant treatments for osteoporosis, bone tumours, and periodontitis. Furthermore, their use on the titanium surfaces of orthopaedic prostheses could represent a possible application to improve the osteogenic processes and osseointegration. According to the study findings, resveratrol, curcumin, and quercetin are reported to have a wide variety of beneficial effects as supplement therapies. The investigated phenolic compounds seem to positively mediate bone metabolism and osteoclast-related pathologies.

Introducción: A nivel mundial la tasa de natalidad desde las últimas décadas ha venido en declive, por lo que adquiere relevancia investigar sus cambios. Objetivos: Cuantificar la tendencia de nacimientos en Chile según rango etario de la madre y sexo biológico del recién nacido en el periodo 2015-2020. Metodología: Se realizó un estudio observacional y ecológico, con los datos obtenidos del banco mundial y DEIS, para la población y nacimientos respectivamente. Los datos se dividieron según las edades maternas en tres grupos: <18 años, 18-34 años y ≥ 35 años. No se requirió comité de ética debido a que no se interviene con personas. Los autores no presentan conflicto de interés. Resultados: Se observó una disminución de los nacimientos del 22,6%, pasando de 244.626 el 2015 a 189.250 el 2020. Los nacimientos en el grupo etario de madres menores a 18 años disminuyeron un 82,13%, reduciéndose de 17.505 a 3.129, el rango de edad materna correspondiente al segundo grupo de 18 a 34 años, ubicó la mayor cantidad de nacimientos, manteniéndose alrededor de un 77,75% (neto), el rango ≥ 35 años, presentó un alza de un 17%, aumentando de 34.648 nacimientos a 40.539. Discusión: En Chile hay un descenso en los nacimientos dado a que la maternidad se está postergando, lo cual puede deberse a la educación sexual implementada en el país y la mayor participación de mujeres en ámbito laboral, esto sugiere una transición de una demografía estable a una regresiva.
Introduction: The birth rate has been declining worldwide since the last decades, so it is important to investigate its changes. Objectives: To quantify the trend of births in Chile according to age range of the mother and biological sex of the newborn in the period 2015-2020. Methodology: An observational and ecological study was conducted, with data obtained from the World Bank and DEIS, for population and births respectively. Data were divided according to maternal ages into three groups: <18 years, 18-34 years and ≥ 35 years. No ethics committee was required due to the fact that we did not intervene with individuals. The authors have no conflict of interest. Results: A decrease in births of 22.6% was observed, from 244,626 in 2015 to 189,250 in 2020. Births in the age group of mothers under 18 years decreased by 82.13%, decreasing from 17,505 to 3,129, the maternal age range corresponding to the second group from 18 to 34 years, located the highest number of births, remaining around 77.75% (net), the range ≥ 35 years, presented a rise of 17%, increasing from 34. Discussion: In Chile there is a decrease in births due to the fact that motherhood is being postponed, which may be due to the sexual education implemented in the country and the greater participation of women in the labor market, suggesting a transition from a stable demography to a regressive one.

INTRODUCTION: Before the start of the GES program in 2002, mortality was 128.2 deaths per million children under 15 years of age (RENCI). This public program managed to ensure the opportunity for diagnosis and treatment in children under 15 years of age and those less than 25 years of age who recur. Objective: To assess how GES has impacted on in-hospital mortality and lethality between1997and 2016. Methods: Retrospective case control study of 28,997 hospital discharges and 12,434 deaths analyzed using Prais-Weinstein time series between the years 1997 to 2016. They prepared contingency tables with data on: hospital discharges, age, sex and forecasts for 2001 and 2016. Fisher's p <0.05 test was used. Results: For the PreGes period an increase of 1.8% in the male crude mortality rate was observed, while for the Post Ges period an increase was observed with a breaking point at the end of 2008, with an increase of 11.04% compared to the PreGes period. An unexpected increase in the female mortality rate was observed.
