Probiotics and oral health : a systematic review
2017
Background Probiotics are microorganisms, mainly bacteria, which benefit the host’s health. Many studies support the role of probiotics as a contributor to gastrointestinal health, and nowadays many authors are trying to prove its influence in oral health maintenance. Objectives To review the published literature with the purpose of knowing the importance of using probiotics as a preventive and therapeutic method for oral infectious diseases management. Material and Methods An electronic search in PubMed database with the keywords “oral health AND probiotics AND dentistry” was conducted. The inclusion criteria were: randomized clinical trials (RCTs) that assess the action of any probiotic s…
Effect of in situ aspartame mouthwash to prevent intrinsic and extrinsic erosive tooth wear
2020
Background The aim was to evaluate whether aspartame regular mouthwash prior to erosive challenges with citric or hydrochloric acids would be able to prevent erosive enamel wear. Material and methods This randomized, single blind in situ study was conducted with 3 crossover phases of 5 days. Polished bovine enamel blocks (n=252) were randomly divided among 6 groups/ 3 phases/ 21 volunteers. The groups under study were: aspartame solution (0.024% of aspartame in deionized water - experimental group), deionized water (negative-control) and stannous-containing solution (Elmex® Erosion Protection Dental Rinse; positive-control); subjected to erosion on citric acid or hydrochloric acid. Four tim…
CanStem303C trial: A phase III study of napabucasin (BBI-608) in combination with 5-fluorouracil (5-FU), leucovorin, irinotecan (FOLFIRI) in adult pa…
2017
TPS3619 Background: Cancer stem cells are considered to be fundamentally important for resistance to therapy, recurrence and metastasis. Napabucasin is a first-in-class cancer stemness inhibitor in development identified by its ability to inhibit STAT3-driven gene transcription and spherogenesis of cancer stem cells (Li et al, PNAS 112(6):1839, 2015). Preclinically, napabucasin sensitizes cancer cells to chemotherapeutics, including 5-FU and irinotecan. Encouraging anticancer activity in advanced CRC was observed in a phase Ib/II (Bendell et al, GI ASCO 2017) study of 63 pts with disease control rate (DCR) of 93% (28/30) and overall response rate (ORR) of 33% (10/30) in FOLFIRI-naïve pts w…
Cholinesterase variants: rapid characterisation by PCR/SSCP and evidence for molecular homogeneity.
1995
We have applied the technique of PCR-SSCP (polymerase chain reaction-single stranded conformation polymorphism) to characterise the molecular basis of cholinesterase deficiency and variants in a Jordanian family. PCR-SSCP proved to be a quick and sensitive method of screening cholinesterase variants in a clinical setting. An AG insertion at position 351 was found to cause a silent allele, for which the parents were heterozygous and three children homozygous. In addition, the father and two sons were heterozygous for an A to G transition at position 209, known to cause the dibucaine resistant variant. No linkage to the K variant was found, which has been reported previously in white populati…
How could multimedia information about dental implant surgery effects patients- anxiety level?
2017
Background To evaluate the effects of different patient education techniques on patients’ anxiety levels before and after dental implant surgery. Material and Methods Sixty patients were randomized into three groups; each contained 20 patients; [group 1, basic information given verbally, with details of operation and recovery; group 2 (study group), basic information given verbally with details of operative procedures and recovery, and by watching a movie on single implant surgery]; and a control group [basic information given verbally “but it was devoid of the details of the operative procedures and recovery”]. Anxiety levels were assessed using the Spielberger’s State-Trait Anxiety Invent…
Prevalence of oral lesions in HIV patients related to CD4 cell count and viral load in a Venezuelan population
2006
Objetivo: Determinar la prevalencia de las lesiones bucales en un grupo de pacientes VIH+, su relación con el contaje de linfocitos CD4 y la carga viral, en una muestra de la población venezolana Materiales y métodos: En el presente estudio se evaluaron 75 pacientes adultos VIH+, provenientes del Centro para la Atención de Pacientes con Enfermedades Infectocontagiosas de la Facultad de Odontología de la Universidad Central de Venezuela. Cada uno de ellos fue examinado clínicamente para la detección de las lesiones presentes en la mucosa bucal. Igualmente se les determinó el contaje de células CD4+ mediante citometría de flujo, así como la carga viral mediante la técnica TR-RCP (Transcriptas…

Objetivos: Este trabajo pretende demostrar que se pueden realizar la mayoría de las intervenciones quirúrgicas de la cavidad bucal en la población pediátrica en un medio ambulatorio, así como valorar y mostrar la actividad realizada en el Máster de Cirugía e Implantología Bucal de la Facultad de Odontología de la Universidad de Barcelona durante el año 2000. Diseño del estudio: Para la realización de este trabajo se ha contabilizado la actividad quirúrgica de las unidades de cirugía bucal y cirugía con láser en la población pediátrica en el Máster de Cirugía e Implantología Bucal de la Universidad de Barcelona. Resultados: De las 3187 intervenciones quirúrgicas realizadas en nuestro servici…
Volumetric changes in alveolar ridge preservation with a compromised buccal wall: a systematic review and meta-analysis.
2020
Background Many studies have addressed socket preservation, though fewer publications considering buccal wall loss can be found, since the literature typically considers sockets with four walls. A systematic review was made on the influence of type II buccal bone defects, according to Elian’s Classification, in socket grafting materials upon volumetric changes in width and height. Material and Methods An electronic and manual literature search was conducted in accordance to PRISMA statement. The search strategy was restricted to randomized controlled trials (RCTs) and controlled clinical trials (CCTs) describing post-extraction sockets with loss of buccal wall in which alveolar ridge preser…
Advanced services and city globalization on the Eastern fringe of Europe
2007
Capital cities in East Central and Eastern European Countries (ECEEC) are changing rapidly. Since the 1990s, the ECEEC capitals have faced the double challenge of the market (the transition process) and of integration in the world economy (the globalization process), which supposes a sufficient development of coordination functions and thus of advanced services concentrated in these cities (city globalization). Their capacity to join the network of global cities is evaluated on the basis of their relative specializations in advanced services and their connections with the rest of the world. The comparative analysis leads to contrasted globalization perspectives. Thus, Budapest, Prague and W…
Factores asociados con el edentulismo en población anciana de Valencia (España)
2013
Objective: To determine the prevalence of edentulism and its association with various socioeconomic factors and oral health habits in the population aged 65-74 years old in the region of Valencia. Methods: A cross sectional study was designed. Thirty-four primary health centers and five nursing homes were chosen at random in the region of Valencia (10-15 voluntary participants per sampling point). Clinical examinations were carried out by three calibrated dentists (kappa>0.85) in the same centers. The total sample consisted of 531 individuals (235 men and 296 women).
