The use of Human Allogenic Graft (HBA) for Maxillary Bone Regeneration: Review of Literature and Case Reports
2012
The use of graft materials is developed from the strong demand to support the complete bone regeneration of the empty socket and to increase the bone volume in treating the atrophies of sites already consolidated and with adverse alveolar bone conditions. A number of graft materials with different origin and mechanism of bone regeneration are available. Autologous graft materials, coming from the same patient, are defined as the gold-standard. The need of a second surgical site and the risk of morbidity and complications may make their use difficult. Human bone allografts (HBA) have been recently introduced, in order to offer an alternative to the autologous grafts. They have demonstrated t…
The Norwegian childhood cancer biobank
2021
Background - The rapidly expanding era of “omics” research is highly dependent on the availability of quality-proven biological material, especially for rare conditions such as pediatric malignancies. Professional biobanks provide such material, focusing on standardized collection and handling procedures, distinctive quality measurements, traceability of storage conditions, and accessibility. For pediatric malignancies, traditional tumor biobanking is challenging due to the rareness and limited amount of tissue and blood samples. The higher molecular heterogeneity, lower mutation rates, and unique genomic landscapes, however, renders biobanking of this tissue even more crucial. Aim - The ai…
[Fluoride content of bottled natural mineral waters in Spain and prevention of dental caries].

Determinación de ácido láctico en el dorso de la lengua: Su relación con la presencia de caries activa
2004
Resumen: Fundamento: el diagnostico de susceptibilidad a la caries es un reto que actualmente tienen que abordar los procedimientos diagnosticos. La presencia de acidos en el medio oral produce una reduccion del pH, siendo el acido lactico el maximo responsable de esta situacion. La posibilidad de detectar sus niveles en la boca puede plantearse como una medida diagnostico adecuada para estimar el riesgo individual frente a la caries. Objetivo y Metodologia: este estudio evalua, de forma preliminar, un test recientemente introducido en el mercado por la casa 3M (Clinpro Cario L-Pop) que permite medir mediante una escala ordinal la presencia de acido lactico en la superficie lingual. Para el…
Relación entre la caries, el índice de masa corporal y la clase social en niños españoles
2017
Abstract Objective: To determine the association between caries, body mass index (BMI) and social class in child population of the Valencia region (Spain) at 6, 12 and 15 years, and study. Methods: In a cross sectional study of 1326 children aged 6 (n = 488), 12 (n = 409) and 15 years (n = 433) who took part in the 2010 Oral Health Survey of the Valencia region, the ICDAS II criteria were employed for diagnosing and coding all the teeth examined. The quantitative BMI values on a continuous scale were grouped into 3 categories (normal weight, overweight, obese) based on a table adjusted for age and gender. The highest-ranking occupation of the parents was taken to indicate the social class o…
Wearing complete dental prostheses - Effects on perioral morphology.
2015
Background: To adequately perform rehabilitation of edentulous patients by a complete removable dental prosthesis (CRDP) is from basic interest to dentists to understand the morphologic changes caused by re-establishment of a physiologic jaw relationship. Anthropometric analyses of standardized frontal view and profile photographs may help elucidate such changes. Material and Methods: Photographs of 31 edentulous patients were compared in relaxed lip closure and after insertion of a CRDP in stable occlusion. 2232 anthropometric distances were raised. Eighteen anthropometric indices reflecting the perioral morphology and its integration in the vertical facial harmony were investigated. Resul…
Bond strength evaluation of the veneering-core ceramics bonds.
2009
The purpose of this study was to determine whether the bond of veneering porcelain to a ceramic core in bilayered ceramics was similar to that of the metal ceramic control of well known behaviour. Six groups of nine specimens each were fabricated, whose dimensions were 15 mm long and 8 mm in diameter at the core, and 2 mm long and 8 mm in diameter for the veneer. The groups were GR. 1 (control group): CrNi alloy/d.SIGN (Ivoclar), GR. 2: IPS e.maxPress/IPS e.maxCeram (Ivoclar), GR. 3: IPS e.maxZirCad/ IPS e.maxZirPress (Ivoclar), GR. 4: IPS e.maxZirCad/IPS e.maxCeram (Ivoclar), GR. 5: Lava Frame (3M ESPE)/ Lava Ceram (3M ESPE) and GR. 6: Lava Frame (3M ESPE)/IPS e.maxCeram (Ivoclar). A shear…
Morphological parameters as predictors of successful correction of Class III malocclusion
2001
The aim of the study was to assess pre-treatment cephalometric parameters and measurements of the size of the apical bases as predictors of successful orthodontic correction of Class III malocclusions. Pre- and post-treatment lateral cephalograms and study models of 80 completed Class III subjects were examined to obtain 23 cephalometric parameters taken mainly from the analyses of McNamara and Schwarz, and to measure the size of the apical bases. Success of occlusal correction was evaluated as the percentage change of peer assessment rating score during treatment, which was used as the dependent variable in multivariate statistical analyses testing the predictive value of the parameters as…
Thermally Induced Isomerisation Kinetics of the 9c11t and 10t12c Conjugated Linoleic Acids in Triacylglycerols as Studied by FT-IR Spectrometry Aided…
2014
Published version of an article from the journal:The Open Spectroscopy Journa. Also available from the publisher:http://dx.doi.org/10.2174/1874383801004010041. Open Access Isomerisation kinetics of the 9c11t and 10t12c Conjugated Linoleic Acids (CLA) in triaclglycerols at isothermal conditions (250, 280 and 325oC) has been studied by infrared spectroscopy. Fifteen micro liter portions of the glycerides were placed in micro glass ampoules and sealed under nitrogen. Several glass tubes containing the same triacylglycerols were then subjected to thermal treatment. The glass tubes were removed at regular time intervals, cut open, and a part of the contents in each glass tube analysed by infrare…
