Dental research in Spain. A bibliometric analysis on subjects, authors and institutions (1993-2012)

BACKGROUND: Bibliometrics is defined as the use of statistical methods in the analysis of a body of literature to reveal the historical development of subject fields and patterns of authorship, publication, and use. Our objective was to characterize Spanish scientific output in Dentistry through the analysis of Web of Science database in a 20- year period. By means of a bibliometric study documents were statistically analyzed using indicators that showed quantitative and qualitative aspects of the production. Specifically, time course of the scientific production within the time span was analysed, as were the journals where the article was published and the categories of Journal Citation Reports (JCR) in which they belong, thematic areas, authorship, and finally authors and institutions with the highest production in Spain. MATERIAL AND METHODS: By means of the design of a specific search strategy previously described in the scientific literature, we recovered all citable documents about Dentistry signed by Spanish researchers and included in the WoS database between 1993 and 2012. RESULTS: A total of 3006 documents fulfilled the search criteria, of which 2449 (81.5%) were published in journals within the category Dentistry Oral Surgery and Medicine and 557 (18.5%) within other categories of the JCR. During the four quinquenniums studied, the production increased quantitatively (8.6-fold) and qualitatively. Finally, the universities of Granada and Complutense of Madrid were the institutions with the highest production and most prolific authors. CONCLUSIONS: The Spanish dental production sharply increased in the last two decades, reaching quantitative and qualitative levels similar to those of the other medical specialties in the country

Trends in World Dental Research: an overview of the last three decades using the Web of Science.

OBJECTIVE: The objective of this paper is to analyse the scientific activity of dental sciences over the last 30 years. MATERIALS AND METHODS: Dental-research output was identified by retrieving all citable dental documents in the Web of Science (WoS) database in the periods 1986-1988, 1996-1998, and 2006-2008. For this, a two-phase search strategy was designed: firstly, output in Dentistry, Oral Surgery, and Medicine (DOSM) Journal Citation Reports (JCR) category journals were compiled; secondly, for journal documents of other JCR categories but related to Dentistry (Non-DOSM), an innovative search strategy was designed based on a double criterion, thematic and institutional. RESULTS: The results showed that DOSM production increased in absolute but decreased in relative terms over the last 30 years. The JCR categories where dental researchers publish also varied. Surprisingly, the geographic distribution of the production shows a growing concentration of the steadily fewer countries, a previously undescribed phenomenon, while the thematic analysis reveals that this production continued to form four broad thematic areas encompassing the remaining specialties: Dental Materials Prosthodontics, Orthodontics, and General Dentistry. CONCLUSIONS: Scientific production in dentistry has changed in the past three decades both quantitatively and qualitatively, as well as their geographical distribution despite being structured around the same specialties. CLINICAL RELEVANCE: In this study, along with some key messages about the key shifts in publication trends, in terms of subject, where published and by whom, we propose a new methodology which could be useful to professionals as well as researchers, in which the exhaustivity and precision rates for scientific information retrieval improve.

Stability and reproducibility of radiometric properties of light curing units (LCUs). Part I: QTH LCUs.

The present study, divided into two parts, analyses the stability and reproducibility of the spectral and energy emission of the present light-curing units (LCUs), quartz tungsten halogen (QTH) and light-emitting diodes (LEDs). In part I, QTH LCUs were studied. The results showed that the QTH LCUs studied presented high stability and reproducibility in terms of their spectral emission with VAF (variance accounting for) values from the Cauchy-Schwarz inequality, all close to 100%. With respect to the energy stability, the QTH LCUs studied can be considered stable under practical clinical conditions, although for some devices the initial irradiance value is critical. This result should be taken into account in those works which is researched in polymerization kinetics of dental materials as well as in clinical practice.

Stability and reproducibility of radiometric properties of light curing units (LCUs). Part II: LED LCUs.

The present work is the second part of a study on the stability and reproducibility of the energy and spectral emission of some light curing units (LCUs). In this part, Part II, LED LCUs were investigated. Results revealed that these devices presented high stability and reproducibility in terms of their spectral emission, with values of VAF (variance accounting for) coefficient calculated from the Cauchy-Schwarz inequality all close to 100%. With respect to energy stability, the LED LCUs presented energy stability except for the third-generation LED LCUs which have several LEDs. For these devices, the law of reciprocity was not fulfilled as irradiance was not constant over exposure time. This result should be taken into account both in works examining the polymerization kinetics of dental materials as well as when these LED LCUs are used in clinical practice.

Prevalencia de infección por Helicobacter pylori en pacientes con gastritis: Correlación anatomopatológica. Experiencia personal

La infección por Helicobacter pylori, es un hecho frecuente sobretodo en países subdesarrollados. Es un factor de riesgo importante para patologías gástricas (gastritis, ulceras, cáncer gástrico, entre otros). OBJETIVO: Determinar la prevalencia de infección por Helicobacter pylori(Hp) en Ciudad Guayana y su correlación con los diferentes tipos de gastritis. METODO: Se recopilaron los datos de 81 pacientes en edades comprendidas entre 13 y 67 años de edad, con promedio de 39,2 años (DE=12,9), que acudieron a la consulta privada de uno de los autores en el Hospital de Clínicas de CECIAMB en Ciudad Guayana. RESULTADOS: El gènero masculino representò el 33,3% (n=27) y el femenino el 66,7% (n=54). La prevalencia de infección por Helicobacter pylori en el grupo de fue de 82,7% (n=67) , con valores superiores al 75% en los grupos de edad < 49 años. No hubo diferencia significativa en cuanto a la prevalencia según la distribución por sexo. La infección por Hp fue mas frecuente en las gastritis de los grados moderados y severos (>85%), con predominio en las gastritis de tipo erosivas (89,7%). En definitiva los altos índices de prevalencia de infección por Helicobacter pylori en el grupo de estudio, se asocian a lesiones de mayor severidad de la mucosa gástrica, lo cual sugieren que la erradicación del mismo debe ser una de los objetivos principales de la terapéutica de estos pacientes.

Infection by Helicobacter pylori (Hp) is very high in the undeveloped countries and it is a risk factor for gastric disease (gastritis, ulcer, gastric cancer and others). OBJETIVE: To determine the prevalence of Hp infection in Ciudad Guayana, and its relationship to the different types of gastritis. METHODS: We gathered the data from 81 patients from ages 13 to 67 years old, with a given average age of 39,2 years (SD=12,9), who attended the private practice of one of the authors at Hospital de Clinicas de CECIAMB in Ciudad Guayana. RESULTS: the male gender represented: 27 (33, 3%) ,and female: 54 (66.7%). The prevalence of Hp infection en the group was 82, 7% (n=67). There were no significant differences regarding prevalence as per gender. The Hp infection was more frequent in moderate and severe gastritis ( 85%) and in erosive gastritis ( 89,7%). In result, the high prevalence of Hp infection in the group studied was associated to major lesions in the gastric mucosa, which suggest that Hp eradication should be one of the main therapeutic goals for these patients.

In vitro evaluation of the accuracy of three electronic apex locators.

The accuracy of three electronic apex locators (EALs) (Justy II, Root ZX, and Neosono Ultima EZ) is evaluated, together with the concordance of the measurements obtained by two different operators. Twenty single-root human teeth were used, sectioning the crown to gain access to the root canal. A first operator (A) determined the reference (or control) length (corresponding to the actual length) for each tooth, after which all teeth were measured individually and independently by the other two operators (B and C). The results obtained with each EAL and by each operator were in turn compared with the corresponding control length. The statistical analysis of the results showed EAL reliability in detecting the apex to vary from 80% to 85% and 85% to 90% (depending on the operator) for the Justy II and Neosono systems, respectively, whereas reliability was found to be 85% for the Root ZX device. These results, combined with a high interobserver concordance, suggest electronic root canal measurement to be an objective and acceptably reproducible technique.

Influence of different composite restoration techniques on cuspal deflection: an in vitro study.

Cuspal deflection produced by polymerization shrinkage was measured after using different composite restoration techniques. This study included 30 healthy premolars embedded in acrylic resin connected to a system that simulated intrapulpal pressure. A small ball was attached to each cuspal vertex as a reference point for intercuspal distance measurements. A large mesio-occlusal cavity was cut in each premolar. All premolars were treated with the same adhesive (ScotchBond) and composite (Tetric Ceram). The teeth were randomly distributed among three study groups: Group 1, filled with two horizontal increments; Group 2, filled with two horizontal increments, the first up to half the cavity height and light cured using a transparent plastic cone (Cerana), and the second filling the remainder of the cavity and Group 3, filled in the same way as Group 2, except that the first increment only filled one-third of the cavity height. The intercuspal distance was measured before beginning the restoration and immediately after polymerization of the first and second increments. Under the experimental conditions used, none of the filling techniques utilized avoided the cuspal deflection phenomenon. Polymerization of the final increment, which binds occlusal enamel in the buccal-lingual plane, was the main cause of cuspal deflection and produced a statistically significant reduction in intercuspal distance vs the baseline measurement in the three study groups. The global deflection ranged from 4 microm to 6 microm, depending on the filling technique used, although the differences among techniques did not reach statistical significance (p<0.05).

Estudio de microfiltración con nuevos materiales alternativos para el sector posterior / Microlakeage study of new posterior filling materials

Fundamento: recientemente, se han comercializado una serie de materiales como los composites condensables, ormoceras y los denominados materiales inteligentes con la finalidad disminuir algunos de los inconvenientes más graves que presentan los composites convencionales. Material y Método: el propósito de nuestro estudio ha sido comparar la filtración marginal de restauraciones de clase II MOD, obturadas con materiales representativos de cada grupo. Grupo 1: Prime & Bond NT.- SureFil, Grupo 2: Ariston Liner- Ariston pHc, Grupo 3: One Coat Bond- Synergy, Grupo 4: One-Step- Pyramid y Grupo 5: Etch & Prime3.0- Definite. Las muestras se termociclaron, y se almacenaron en azul de metileno al 2 por ciento, durante 7 días a 37º C. Después de ser seccionados longitudinalmente, se evaluó la microfiltración mediante observación con lupa estereoscópica a 10x. Resultados: El análisis estadístico indica que no existen diferencias significativas en la filtración entre los grupos 3, 4 y 5, pero estos tres grupos sí presentan diferencias significativas respecto a los dos restantes: 1 y 2, que muestran mayores tasas de filtración. Conclusiones: la filtración en los grupos obturados con Prime & Bond- SureFil y Ariston Liner- Ariston pHc es significativamente mayor que en los grupos en que se utilizó One Coat Bond- Synergy, One-Step- Pyramid y Etch & Prime3.0- Definite.

[Defects in the visual field in resective surgery for temporal lobe epilepsy]. / Defectos del campo visual en la cirug a resectiva de la epilepsia del l bulo temporal.

INTRODUCTION: Temporal lobe resection is the most used procedure in epilepsy surgery. Visual field defects after resection are frequent. AIM. We try to detect the frequency and severity of visual field defect after anterior temporal lobectomy (ATL) and to study the functional consequences. PATIENTS AND METHODS: We studied 30 patients with refractory temporal lobe epilepsy (15 men, 12 51 years, m= 32.9), in which ATL was performed (11 right, 19 left). The neocortical and hippocampal resection was variable. Visual field was studied with computerized campimetry type Humphrey. Our survey was filled to study the campimetric consequence, seizures incidence, quality of life and surgery satisfaction. RESULTS: Some campimetric disturb was found in 27 patients (90 %), superior or minor homonimus quadantapnosia in 18 (60 %), major one 8 and homonimus hemianopsia in one. Incongruent defects appeared in 19. The bigger neocortical and hippocampal resection was, the bigger defect, with exceptions. Only patient with a hemianopsia was conscious the deficit. 20 patients (66.6 %) were seizures free in the last year. 28 had better quality of life and 29 (96.6 %) would have chosen surgery again. CONCLUSION: Visual field defects after ATL, although frequent, have little functional consequences and in quality of life. The quality of life is better when seizures stopped. After ATL patients are very glad with their decision.

A comparative study of apical leakage of Endomethasone, Top Seal, and Roeko Seal sealer cements.

A comparison was made of the apical leakage of three sealers. Fifty single-root human teeth were randomly divided into 5 groups (n = 10; 3 experimental and 2 control). The teeth of the positive-control and experimental groups were instrumented with K-type files to size 45. The experimental groups were obturated by laterally-vertically, condensed gutta-percha with Endomethasone, Top Seal, or RSA sealer cements. The positive-control group was nonobturated and the negative-control group was noninstrumented. The root surfaces were then coated with nail varnish (except the apex in the experimental groups) and immersed in black ink (for 1 week at 37 degrees C). The statistical evaluation of the results obtained by clearing and cross-section techniques showed no significant differences between sealers. Leakage, as determined by the clearing technique, was significantly greater than that quantified by cross-section analysis.
