Scanning electron microscopy assessment of the load-bearing capacity of cad/cam-fabricated molar crowns.

Braz Oral Res 2020 17;34:e035. Epub 2020 Apr 17.

Dicle University, Faculty of Medical Science, Department of Anatomy, Diyarbakır, Turkey.

Although fiber-reinforced composites are commonly used in dental practice, whether fiber-reinforced crowns and fixed partial dentures can be used as definitive prostheses remains to be determined. This study used scanning electron microscopy to evaluate the load-bearing capacity of non-reinforced and fiber-reinforced composite (FRC) molar crowns prepared by computer-aided design/computer-aided manufacturing (CAD/CAM). The crowns were fabricated from three empirical FRC blocks, one empirical composite block, and one commercial ceramic block. Read More

Plasma rich in growth factors (PRGF) in non-surgical periodontal therapy: a randomized clinical trial.

Braz Oral Res 2020 17;34:e034. Epub 2020 Apr 17.

University of Milan, Department of Biomedical, Surgical & Dental Sciences, Milano, Italy.

The aim of this split mouth, double blinded, randomized clinical trial was to evaluate the clinical efficacy of use of Plasma rich in growth factors (PRGF) as an adjunct to scaling and root planing (SRP) in the treatment of periodontal pockets. Twenty six patients (15 males, 11 females) diagnosed with generalized periodontitis with Pocket Depth > 5mm and plaque index score < 1.5, were randomly allocated by using computer generated random sequence, into two groups, one treated with intra-pocket application of PRGF adjunct to SRP and other with SRP alone.

Colgate Palmolive Company, Global Technology Center, Piscataway, NJ, USA.

Periodontal diseases are considered a worldwide public health problem, owing to their high prevalence in developed and developing countries. Periodontitis may lead to tooth loss, which can impact oral health-related quality of life. Gingivitis and periodontitis have been extensively studied regarding their etiopathogenesis, epidemiology, prevention and treatment outcomes. Read More

Periodontal disease and its impact on general health in Latin America. Section V: Treatment of periodontitis.

Universidade de Guarulhos - UnG, Dental Research Division, Department of Periodontology, Guarulhos, SP, Brazil.

Gingivitis and periodontitis are associated with a negative impact on Oral Health Related Quality of Life (OHRQoL), exerting a significant influence on aspects related to the patients' function and esthetics. Periodontitis has been associated with several systemic conditions, including adverse pregnancy outcomes, cardiovascular diseases, type 2 diabetes mellitus (DM), respiratory disorders, fatal pneumonia in hemodialysis patients, chronic renal disease and metabolic syndrome. The aim of this paper was to review the results of different periodontal treatments and their impacts on patients' OHRQoL and systemic health. Read More

Strategies for the prevention of periodontal disease and its impact on general health in Latin America. Section III: Prevention.

Braz Oral Res 2020 9;34(supp1 1):e025. Epub 2020 Apr 9.

Maimónides University, Faculty of Health Sciences, Department of Periodontics, Buenos Aires, Argentina.

Dental plaque removal and the understanding of risk factors, risk indicators and social determinants are important components in the prevention of periodontal disease. Periodontal diseases and dental caries are largely preventable conditions, but require a "common risk factor approach" with non-communicable diseases with the purpose of improving their prevention and control, and positive impact on health. The aim of this consensus was to identify the evidence and gaps in periodontal prevention in Latin American, and to propose individual and collective recommendations for the population, health professionals, dental practice and government.

Maimónides University, Faculty of Health Sciences, Department of Periodontics, Buenos Aires, Argentina.

A high level of general and oral health are invaluable assets, a factor not always considered a basic human right for their better life quality. The mouth is a critical point of contact with the external environment, which is established when we talk, chew, swallow and when food digestion begins. From a perspective of the human condition, the mouth is crucial for the integration of sound, social appearance of the individual, and is one of the fundamental components of overall health.

Latin American Oral Health Association - LAOHA, São Paulo, SP, Brazil.

The epidemiological data on gingivitis and periodontitis in Latin America are scarce, as the majority of the Latin American studies have analyzed probing depth instead of clinical attachment loss. Reported data have shown high variations in results between different Latin American countries, with the main causes of these differences being the clinical case definition and methodological strategies used. In general, data have revealed that the prevalence of periodontal disease is higher in Latin Americans than in populations in the USA or Europe. Read More

Universidade de São Paulo - USP, School of Dentistry, Department of Oral Pathology, São Paulo, SP, Brazil.

The aim of our study was to isolate populations of keratinocyte stem cells based on the expression of cell surface markers and to investigate whether the culture could affect their phenotype. keratinocytes from human oral mucosa were sorted based on the expression of the epithelial stem cell markers p75NTR and CD71. We also examined the co-expression of other epithelial stem markers such as integrins β1 and α6 and their stem cell-like proprieties in in vitro assays. Read More

Upregulation of IL-10 expression inhibits the proliferation of human periodontal ligament stem cells.

Braz Oral Res 2020 27;34:e030. Epub 2020 Mar 27.

Nanjing University, Medical School, Department of Periodontology, Nanjing City, Jiangsu Province, China.

The abnormal increase in proliferation rate of human periodontal ligament stem cells (PDLSCs) is considered to be involved in the pathogenesis of periodontitis, a disease in which the IL-10-mediated anti-inflammatory pathway plays a critical role. This study aimed to investigate the involvement of microRNA-466l in periodontitis and to explore the possible interaction between IL-10 and microRNA-466l. PDLSCs were obtained from periodontitis-affected teeth and healthy control teeth. Read More
