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. Material and methods A retrospective study was carried out in a subpopulation of 879 Spanish children in southern Europe aged between one and 7 years old, with primary and early mixed dentition. Clinical and radiological records were obtained from all pediatric patients who presented trauma to the primary teeth, with a follow‐up period of 3–5 years. Results A total of 21.72% of children examined had some kind of dental trauma and the most common age range for injuries to the primary teeth was 1–3 years old. The most common injuries in deciduous teeth were subluxation (47.29% of injuries affected the periodontal ligament), intrusion (23.15%), and avulsion (13.63%). On the other hand, comparatively more complications were recorded as a result of intrusion (32 of 47 intruded teeth). Conclusions In this Spanish subpopulation, a pediatric dental consultation as a result of traumatic dental injuries in primary dentition is most frequent in 1‐ and 2‐year‐olds, and subluxation is the commonest injury in the primary dentition. In turn, intrusion is associated with an increased frequency of complications in both the deciduous and the permanent teeth.
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. The objective of the present article is to offer the audience a complete and comprehensive review of the main applications that have been developed in dentistry, by the use of these materials, during the last two decades. It was shown how these materials are improving the treatments in mainly all the important areas of dentistry, such as endodontics, periodontics, implants, tissue engineering and restorative dentistry. The scope of the present review is, subsequently, to revise the main applications regarding nano-shaped materials in dentistry, including nanorods, nanofibers, nanotubes, nanospheres/nanoparticles, and zeolites and other orders porous materials. The results of the bibliographic analysis show that the most explored nanomaterials in dentistry are graphene and carbon nanotubes, and their derivatives. A detailed analysis and a comparative study of their applications show that, although they are quite similar, graphene-based materials seem to be more promising for most of the applications of interest in dentistry. The bibliographic study also demonstrated the potential of zeolite-based materials, although the low number of studies on their applications shows that they have not been totally explored, as well as other porous nanomaterials that have found important applications in medicine, such as metal organic frameworks, have not been explored. Subsequently, it is expected that the research effort will concentrate on graphene and zeolite-based materials in the coming years. Thus, the present review paper presents a detailed bibliographic study, with more than 200 references, in order to briefly describe the main achievements that have been described in dentistry using nanomaterials, compare and analyze them in a critical way, with the aim of predicting the future challenges.
BackgroundGiven 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 MethodsA 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.ResultsThe contrast test was based on Wilks’ Lambda, which assumed a value of 0.120 (F = 467.28; p<.001), demonstrating statistically significant differences among knowledge levels in the three dimensions. The effect size for these differences, measured by partial eta squared, was very high (η2p = 0.88). Such parameters were also analyzed to search for potential differences according to professional experience, with differences being exposed as non-significant at the 0.05 level: etiology (T = 1.60; p = 0.113), diagnosis (T = - 0.17; p = 0.868), and treatment (T = 1.10; p = 0.273).ConclusionsOur study found that, even though clinicians are generally skilled regarding the knowledge of the etiologic that explain the diagnosis of TMD, they have room for improvement in terms of TMD management compared to the other two areas studied. General dentists could benefit from specific educational programs enhancing TMD management skills. Key words:Temporomandibular disorders (TMD), knowledge and management.

Objectives: Placing implants in the posterior maxillary area has the drawback of working with scarce, poor quality bone in a significant percentage of cases. Numerous advanced surgical techniques have been developed to overcome the difficulties associated with these limitations. Subsequent to reports on the elevation of the maxillary sinus through the lateral approach, there were reports on the use of the crestal approach, which is less aggressive but requires a minimal amount of bone. Furthermore, it is more sensitive to operator technique, as the integrity of the sinus membrane is checked indirectly. The aim of this paper is to review the technical literature on minimally invasive sinus lift and compare the advantages of different techniques with Intralift™, a new technique. Study Design: The present study is a review of techniques used to perform minimally invasive sinus lift published in Cochrane, Embase and Medline over the past ten years and the description of the crestal sinus lift technique based on minimally invasive piezosurgery, with the example of a case report. Results: Only eight articles were found on minimally invasive techniques for sinus lift. The main advantage of this new technique, Intralift, is that it does not require a minimum amount of crestal bone (indeed, the smaller the width of the crestal bone, the better this technique is performed). The possibility of damage to the sinus membrane is minimised by using ultrasound based hydrodynamic pressure to lift it, while applying a very non-aggressive crestal approach. Conclusions: We believe that this technique is an advance in the search for less traumatic and aggressive techniques, which is the hallmark of current surgery. Key words: Sinus lift, surgical technique, minimally invasive surgery, ultrasound surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
