Bibliographic Study

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.

Microscopic Techniques

Cutting of the dental hard tissues is an integral part of restorative dentistry. Cutting of the root dentine is also needed in preparation prior to endodontic treatment, with significant commercial investment for the development of flexible cutting instruments based around nickel titanium (NiTi) alloys. This paper describes the evolution of endodontic cutting instruments, both in materials used, e.g. the transition from stainless steel to NiTi, and the design of the actual instruments themselves and their method of activation—by hand or motor driven. We have been examining tooth-cutting interactions microscopically for over 25 years using a variety of microscopic techniques; in particular, video-rate confocal microscopy. This has given a unique insight into how many of the procedures that we take for granted are achieved in clinical practice, by showing microscopic video images of the cutting as it occurs within the tooth. This technology has now been extended to allow imaging of the endodontic instrument and the root canal wall for the first time. We are able to image dentine distortion and crack propagation during endodontic filing of the root canal space. We are also able to visualize the often claimed, but seldom seen action of contemporary endodontic instruments.

ABSTRACT Background Restoration failure due to secondary caries is a continuing problem in restorative dentistry. Aims and objective The present study is undertaken to see whether various fluoridated dentifrices recharge fluoride releasing restorative materials and, comparatively evaluate their recharging capabilities. Materials and method Materials used in the study are Fuji II LC, Compomer, Teethmate F1, Alfadent sealant. Dentifrices used are Sodiumflouride and Sodiummonoflurophasphate releasing. All restorative materials were mixed according to manufacturer's instruction and standardized test pellets were made using autoclaved instruments in sterile Teflon moulds. These test pellets were divided in various groups and brushed with various fluoridated and nonfluoridated dentifrices accordingly . Results were evaluated stastically using ANOVA, t-test and correlation coefficient for which regression lines were drawn. It was concluded that Sodiumfluoride containing dentifrices recharged fluoride releasing restorative material more than Sodium monoflurophasphate containing dentifrices

Dentin Adhesive

The advent of dentin adhesive technology in endodontics has made monoblock a well known concept in endodontics. However it has created many controversies on whether monoblock would reinforce the roots and provide a superior coronal seal.In this review, attempts have been made to understand monoblock in a broader aspect and understand how the monoblock concept can be applied to the materials used till date which rehabilitates the root canal space. The potential of currently available bondable materials to achieve mechanically homogeneous units with root dentin is then discussed in relation to the classical concept in which the term monoblock was first employed in restorative dentistry and subsequently in endodontics.

In dental care is necessary to isolate the tooth the oral environment (saliva, tongue, cheek, etc) with some type of retractor. This work aimed to propose a new model of instrumental low cost that assists in dental treatment. The instrumental was virtually designed and tested with the characteristics of the materials used in its manufacture: Solid stainless steel wires of 7 mm, acrylic resin and steel tape. To simulate its functionality was modeled a mouth with the actual measurements via the free software Blender 2.49b. To evaluate the simulation results of the test type black box, where you can observe the operation of the simulator were used. After testing various virtual instruments with the same measurements to assess its performance were made clinically. It was concluded in the simulation and clinical tests that the instrument is stable and performs the removal of anatomical structures adjacent to the tooth, even in cases of patients with positive macroglossia can be used for different types and sizes of arches, in the absence of any tooth can be fixed in any tooth, getting the desired position by professional optimizing the same time.

The therapy of non-caries cervical lesions is an important problem in restorative dentistry, for the ambiguous aetiology, clinical diagnoses and for the selection of restorative procedure. Aim: The aim of this work was to clinically check the efficiency of non-caries cervical lesions restoration depending on materials used for restorative fillings. Materials and methods: Clinical researches covered 62 teeth of different morphology group at the patients of both gender and of different age. The restoration of gingival lesions, with no previous preparation, was done with composite adhesive system SINGLE BOND/Valux Plus (3M) (30 teeth) and with campomer DYRACT AO (Dentsplay) (32 teeth). The fillings were estimated on the checkups which took place on 3,6 and12 months applying modified criteria according to Ridge and Cvar. Results: The acquired results showed that after 3 to 6 months there were no changes at none of examined parameters and all the fillings got maximal mark A. 12 months latter, in the two cases with composite filling, the marginal adaptation got the mark B (607%). The marginal adaptation at two teeth restored with compomers got the mark B (6.3%) Postoperative sensitiveness phenomenon, marginal discoloration and secondary caries weren?t registered in none of the cases after the observation period of 12 months. Conclusion: For the restoration of non-caries cervical lesions, composite materials with suitable adhesive system and the new generation of compomers could be used. .
