Nanomaterials in Dentistry: State of the Art and Future Challenges.

Nanomaterials are commonly considered as those materials in which the shape and molecular composition at a nanometer scale can be controlled. Subsequently, they present extraordinary properties that are being useful for the development of new and improved applications in many fields, including medicine. In dentistry, several research efforts are being conducted, especially during the last decade, for the improvement of the properties of materials used in dentistry.

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.

Effect of mineral trioxide aggregate (MTA) pulpotomies in primary molars on their permanent tooth successors.

Purpose: To determine the long-term success rate of white MTA pulpotomies in primary teeth and its influence upon eruption and calcification of the permanent successor, as well as other key clinical and radiographic parameters.

Methods: A total of 138 molars from participants between 2-10 years of age were included. Clinical and radiographic parameters were monitored in the primary and/or permanent successor at 6, 12, 18, 24, 30, 36, 42, and 48 months or until eruption of the permanent successor, using the contralateral tooth as control.

Prevalence and complications of trauma to the primary dentition in a subpopulation of Spanish children in southern Europe.

Background: During the first years of life, when children begin to walk and socialize, they are particularly vulnerable to traumatic injuries to the primary teeth; indeed, after dental caries, such injuries are the second most frequent cause of pediatric dental consultation. Nonetheless, the reported prevalence of trauma to the primary teeth varies depending on the literature source, type of injury, the patient's age, and the most common associated complications.

Aim: To analyze new epidemiological data and complications associated with traumatic injuries to the primary teeth of Spanish children.

The relationship between malocclusion, benign joint hypermobility syndrome, condylar position and TMD symptoms.

The current study investigated the association between temporomandibular disorders, malocclusion patterns, benign joint hypermobility syndrome and the initial condylar position. One hundred sixty-two subjects were analyzed using the Rocabado Temporomandibular Pain Analysis; Helkimo Index parameters; the Carter-Wilkinson modified test; and a mounting cast with condylar position indicator registration (MPI). The study revealed a significant association between: 1.
