Abstract

Background: Nanotechnology can be defined as the science involved in the design, synthesis, characterization, and application of materials and devices whose smallest functional organization in at least one dimension is on the nanometer scale. Aim: The aim of this cross-sectional study was to assess the knowledge and attitude of dental students and intern practitioners about the nanotechnology in dentistry at KSA. Materials and methods: An online questionnaire was distributed through the link shared to dental students and intern practitioners via social networking websites. A simple random sample comprised of 306 participants almost distributed across the five geographical regions of Saudi Arabia. The questionnaire was designed to obtain information about the basic knowledge and attitude about nanotechnology being used worldwide for better dental treatment. It consisted of two parts: Part A: Biographic and demographic data of the participants. Part B: Knowledge and Attitude towards nanotechnology in dentistry was focused. Statistical analysis of the data was performed. Frequency distribution and Chi-square analysis were used to determine if there were any relationships and statistically significant differences between knowledge and attitude of nanotechnology in dentistry with biographic and demographic factors. Results: Out of the 306 participants' response, 213 (69.3%) had heard about the nanotechnology and the main source of information about nanotechnology in dentistry was Internet (32.1%). Only (26.4%) of participates use nanomaterial in their university and (73.6 %) didn't use it. (52.1%) of them strongly disagree with nanotechnology will have a wide application in future. Conclusion: This study revealed that there is lack of awareness on Nanotechnology application in dentistry among the dental students and intern practitioners at Saudi Arabia.

... Nanotechnology is undoubtedly likely to improve dental preventions and treatments but it is still in development phase and its use in clinical settings is limited by concern of safety and cost-effectiveness [18]; this may be the reason for the observations noted in this study. Similarly, awareness about the application of nanotechnology in dental implants among the respondents in this study was high compared to a previous study that reported a low awareness [19]. Furthermore, the use of nanotechnology in various fields is an evolving process which is sure to enhance the various prevailing dental procedures with the possibility of more materials and procedures based on nanotechnology in the future [20]. ...
... Nano particles in composite were rightly reported by a majority of the respondents as part of development of dental materials in nanodentistry. A finding that is similar to a report among dental students [17,19]. This may be because Nanohybrid and nanofilled resin-based composites are readily available types of composite restorative materials and nanoparticles have been utilised extensively in composite resin [1]. ...
... However, about half of the respondents in this study recognised the use of nanorobots; a proportion that is higher than previously reported among dental students and interns [19]. ...

Background: The potentials of nanotechnology in the field of dentistry are enormous. This study evaluated the level of awareness and knowledge of a population of Nigerian dentists about nanodentistry. Method: This was a descriptive cross-sectional study of a population of Nigerian dentists. The study assessed the level of awareness regarding 6 different areas of dentistry where nanotechnology has been utilized and also assessed the knowledge of nanodentistry among the respondents. Results: Awareness of the use of nanotechnology in development of dental materials was highest among the respondents. Only 8.8% of the respondents were extremely aware that bottom-up approach and top-down approach are approaches to nanodentistry while those that were not at all aware about bottom-up approach and top-down approach as approaches to nanodentistry accounted for 39.7% respectively. A higher proportion (41.5%) of the respondents reported excellent level of knowledge (CI 27-9-41-5) while 38.2% had a good level of awareness regarding areas of dentistry where nanotechnology has been utilized (CI 27.9-48.9). Conclusion: The overall level of knowledge and awareness of nanodentistry among the study population was fair with the knowledge of its application in dental material science high. Continuous education on the applications of nanoparticles in all aspects of dentistry will go a long way to improve the knowledge and awareness of nanodentistry.

... Thus students are expected to be aware of basic nanotechnology science. The questioner was distributed to (417) student, all five stages were participated, about 58% of students had an idea about nanotechnology, while 42% of students did not had an idea about nanotechnology and this result differ from the result of Asmaa et al [13] study who found 69.7% had heard of nanotechnology, whereas 30.3% had never heard of nanotechnology, and results of Sakr et al. [14] in which 69.3% of participants had heard of nanotechnology. This result may be due to the deficiency in the curriculum about this topic in all study stages or may be it mention in curriculum but briefly. ...

Objective: Nanotechnology is "a term that involve a spectrum of technologies, techniques and processes that can deal with a matter at the nanoscale". Many new diagnostic modalities and nano-delivery systems that have been introduced by improvement of the materials mechanical and physical properties' in the field of dentistry.The aim of study was to evaluate undergraduate dental student perceptions of nanotechnology in Iraq. Method: This study was based on an online questionnaires distributed to students of dentistry for the five stages, a number of students (417), the questioner include general information and then questions distributed into four axes. The generation of a single variable in the second, and third axes was analyzed by five point of Likert scale. Result: 58% of students had an idea about nanotechnology, while 42% of students did not had an idea about nanotechnology. the largest percentage of students have difficulties in accessing information about nanotechnology. The largest percentage of the student want to introduce the nanotechnology in the curriculum, also largest percentage of the student wish to search information about the nanotechnology and support the use of nanotechnology in clinic. Conclusion: Based on the results of this study, the dental students of University of Babylon have inadequate knowledge about nanotechnology and its applications in field of Dentistry. We think that the incorporation of nanotechnology in the dentistry curriculum of colleges in Iraq was mandatory.
... Of the participants, 69.7% had heard of nanotechnology, whereas 30.3% had never heard of nanotechnology, and these results are similar to the results in a study by Sakr et al. in which 69.3% of participants had heard of nanotechnology. [12] But, Ali et al. study showed that only 50.8% of their students knew about nanotechnology. [13] In our study, most of the students who had not heard of nanotechnology were 3rd and 4th year students. ...
... Sakr and Alhablain [45] studied the knowledge and attitude of dental students and intern practitioners about usage of nanotechnology in dental practice.

Chapter
Microplastics in the environment have become a public health concern over the past few years. Items of toothpaste and composite restorative materials are the primary dental products that contribute to the microplastic pollution of the environment. In terms of dental origin, toothpaste containing plastic particles <5 mm, form the source of primary microplastics. Secondary microplastics are formed from the resin-based composite restorative materials which degrade within the oral cavity or may be released during the process of finishing and polishing of restorations. At the same time, there is minimal awareness amongst the population regarding the use of microplastics in personal-care products. The prolonged use of toothpaste containing microbeads can cause abrasion of tooth enamel and dentine. The microbeads can get entrapped in the gingival sulcus leading to gingivitis and periodontitis. The resin-based composites used as direct restorative materials, pit and fissure sealants and in CADCAM milling can release monomers like Bisphenol A-glycidyl methacrylate (Bis-GMA) which is a potent environmental hazard as it gets dumped in the landfill. Studies have confirmed the damage to aquatic life caused by microplastics which can lead to the extinction of various aquatic species in future. They also get adsorbed to biotoxins and through the process of bioaccumulation enter the food chain. A few countries have enacted legislation which limits the use of microplastics in health care products. However, many do not impose such strict regulations. Therefore, an educational and regulatory approach toward the use of microplastics is mandatory to control the emerging threat of microplastics to the environment. This chapter is intended to create awareness among the public about the hazardous effects of microplastics in dental care products and promote insights into policymaking.
