Nano technology is the science and engineering related to particles sized 10-9 of a meter. Albeit, the small size, they have opened up a huge array of possibilities for this world. By the inclusion of nanoparticles in various materials not only, the field of engineering but also, medical and dentistry have been benefitted largely. Researchers have manipulated the particles at a molecular and atomic level, which have opened up huge possibilities for the same material. The recent advances have helped to achieve accurate and fast diagnosis, helped to prolong the longevity of dental materials and hence helped to create a healthy oral environment. However, with all these developments, it is important that we focus on the shortcoming or the hazards too and carefully comply with the same before its long-term application. Therefore, this article focuses on the basis, all the present applications of Nano dentistry and the potential it holds for the field of dentistry in future.

Lamellar ichthyosis (LI) is a rare genetic skin disorder that is present at birth, with an incidence of <1:300,000 in different parts of the world. However, there is little evidence of oral manifestations. Oral symptoms and oral rehabilitation of this condition are mostly unknown. This case report reiterates the need for proper dental diagnosis, treatment planning, and follow-up for a holistic approach. Here, we describe the oral manifestations and successful complete oral rehabilitation procedure performed in a 19-year-old female patient who had prediagnosed LI with skeletal class III jaw discrepancy due to maxillary deficiency.

Background. To evaluate and compare the shear bond strength of feldspathic porcelain to four distinctively surface-treated Ni-Cr and Co-Cr alloys and to assess the impact of oxidation-heat treatment on porcelain to base metal alloy bond strength. Methods. 40 specimens each of nickel-chromium alloy and cobalt-chromium alloy were cast. A total of four groups of specimens were created. Group I was surface-treated by sandblasting with 50 μm alumina particles, Group II was surface-treated by sandblasting with 110 μm alumina particles, Group III and Group IV were surface-treated with 250 μm alumina particles. In Group IV, after sandblasting initially with 250 μm alumina particles, the alloys were subjected to oxidation and resandblasting with 250 μm alumina particles. Each of the specimen was coated with opaque and body porcelain and fired to a total thickness of 2 mm porcelain. A universal measuring machine was used to assess shear bond strength at a crosshead speed of 0.5 mm/min. Results. Two-way ANOVA followed by Tukey’s post hoc test was used to assess the significant difference within the groups. Unpaired t-test was used for the intergroup comparison of the obtained data. The study showed that the size of the air abrasion particles used for sandblasting significantly influenced the porcelain to metal surface bond strength, with p value <0.001. The bond strength values of the two alloys tested showed no major variations. Result also showed that oxidation influences the metal-ceramic bond strength. Conclusions. The bond strength of the metal-ceramic interface is influenced by the alloy’s surface treatment. The oxidation process impacts the bond strength of the metal-ceramic system.
