Sport-related concussion research agenda beyond medical science: culture, ethics, science, policy.

The Concussion in Sport Group guidelines have successfully brought the attention of brain injuries to the global medical and sport research communities, and has significantly impacted brain injury-related practices and rules of international sport. Despite being the global repository of state-of-the-art science, diagnostic tools and guides to clinical practice, the ensuing consensus statements remain the object of ethical and sociocultural criticism. The purpose of this paper is to bring to bear a broad range of multidisciplinary challenges to the processes and products of sport-related concussion movement.

Solidarity and Public Health.

We argue that an unqualified use of the term solidarity in public health is not only equivocal but problematic toward the ends of public health. The term may be deployed normatively by public health advocates to strengthen the bonds among public health practitioners and refer to an ideal society in which the importance of interdependence among members ought to be acknowledged throughout the polity. We propose an important distinction between partisan solidarity and societal solidarity.

The Influence of Power on Leisure: Implications for Inclusive Leisure Services.

Many people experience domination as they encounter oppression and marginalization because of power differentials limiting their leisure. We rely on Foucault for guidance to examine connections between power and opportunities for people to be included in leisure and recognize that, like Foucault, we experience privilege. Considering such privilege, we explore power and people connections, scrutinize ways power influences leisure, and examine methods to promote or resist power to increase leisure.

Analysis on the predictive value of different variables in pulp stones appearance frequency and its pulpal response to cold stimuli.

This study evaluated the presence of pulp stones in a Seville population, correlating their presence and size with state of the crown and pulp response to cold stimuli, encompassing variables such as age, gender, location (arch and teeth group). The study included 1090 teeth corresponding to 146 patients. Each patient underwent a visual examination, periapical radiographs and sensibility tests.

Knowledge and management of temporomandibular joint disorders by general dentists in Spain.

Background: Given the importance of temporomandibular disorders (TMD), we tried to assess general dentists' knowledge regarding etiology, diagnosis, and treatment in order to understand their attitude.

Material And Methods: A sample of 130 general dentists answered a 16-item questionnaire on three areas - etiology, diagnosis, and management of common temporomandibular disorders - as well as a question on the need for continuous education regarding TMD management in common clinical practice in Spain. Given that the descriptive statistics achieved reflect significantly different values among means in each area, a variance analysis for repeated measurements was applied in order to contrast differences among etiology, diagnosis, and management knowledge levels.

Influence of root canal instrumentation and obturation techniques on intra-operative pain during endodontic therapy.

Objective: To analyse the influence of root canal instrumentation and obturation techniques on intra-operative pain experienced by patients during endodontic therapy.

Method And Materials: A descriptive cross-sectional study was carried out in Ponferrada and Sevilla, Spain, including 80 patients (46 men and 34 women), with ages ranged from 10 to 74 years, randomly recruited. Patient gender and age, affected tooth, pulpal diagnosis, periapical status, previous NSAID or antibiotic (AB) treatment, and root canal instrumentation and obturation techniques were recorded.

External apical root resorption in maxillary root-filled incisors after orthodontic treatment: a split-mouth design study.

Introduction: The purpose of this study was to compare, in a split mouth design, the external apical root resorption (EARR) associated with orthodontic treatment in root-filled maxillary incisors and their contralateral teeth with vital pulps.

Methodology: The study sample consisted of 38 patients (14 males and 24 females), who had one root-filled incisor before completion of multiband/bracket orthodontic therapy for at least 1 year. For each patient, digital panoramic radiographs taken before and after orthodontic treatment were used to determine the root resortion and the proportion of external root resorption (PRR), defined as the ratio between the root resorption in the endodontically treated incisor and that in its contralateral incisor with a vital pulp.

Relationship between smoking and endodontic variables in hypertensive patients.

Introduction: The aim of this study was to investigate the relationship between smoking and the prevalence of apical periodontitis and root canal treatment in hypertensive patients.

Methods: In a cross-sectional study, the records of 100 hypertensive patients, 50 smokers and 50 nonsmokers, were examined. Periapical status of all teeth was assessed by using the periapical index score.
