Background: The nanotechnologies have been applied for dental restorative materials manufacturing such as glass ionomer cement, composites, tooth regeneration, and endodontic sealers. The study aimed to investigate the chemical bond of conventional glass ionomer cement and to evaluate the addition of different concentrations of silver nanoparticles (AgNPs) on the quality of the chemical bond of glass ionomer cement to primary dentin.Methods: Silver nanoparticle (AgNP) powder was added in concentrations of 0.2, 0.4, and 0.6% to the conventional powder of GIC Fuji II. Then, the powder was added to the liquid and mixed with the recommended powder/liquid ratio of 3.6:1 g. The Fourier-transform infrared spectra (FTIR) of teeth with 0.2%, 0.4%, and 0.6% w/w of silver nanoparticles in GIC fills and the control tooth were obtained. The conventional glass ionomer was used as a control group. The control and the plain silver tooth were subjected to FTIR analysis using an ATR–FTIR spectrophotometer (ThermoFisher Scientific, Waltham, MA, United States) with zinc selenide (ZnSe) ATR crystal (attenuated total reflection) and OPUS v7.5 software. All spectra were recorded in the range of 500–3,500 cm−1 in the transmission mode with an ATR module.Results: The AgNPs added at 0.2, 0.4, and 0.6% concentration to GIC provided some information in the context of bond interaction with the dentin. Various bond peaks were seen for calcium, carbonate, phosphate, and amide. In our study, only the amide and phosphate were generated. The amide peaks were almost similar to the control, 0.2%, 0.4%, and 0.6%, with the peaks in the range of 1250–1650 cm−1. There was a clear shift in the phosphate peak from the control, 0.2, and 0.4%, which was about 1050 cm−1, whereas for 0.6%, there was a clear shift from 1050 cm−1 to 880 cm−1.Conclusion: GIC supplemented with AgNPs showed that a concentration above 0.4% of AgNPs altered the bond quality in dentin interaction. In conclusion, adding AgNPs at a minimal level improves the mechanical properties and maintains the same bond quality as GIC.

Human eruption is a unique developmental process in the organism. Delayed tooth eruption is the emergence of a tooth into the oral cavity at a time that deviates significantly from norms established for different races, ethnicities, and sexes. The eruption time of primary teeth is very important for planning and diagnosing of certain growth developments. The present article gave a review on delayed tooth eruption and its pathogenesis.

A bstract Aim and objective The aim and objective of this paper is to report a combination of various dental anomalies in a healthy pediatric patient. Background A combination of dental anomalies was reported, particularly in patients with syndromes or chromosomal abnormality. Very few cases of multiple defects have been described in patients with no generalized abnormality. Case description This article reports the case of a 10-year-old female healthy patient who was found to have multiple dental anomalies which include: (1) bilateral congenitally missing 2nd premolar, (2) bilateral peg laterals, (3) an abnormal sequence of eruption in the lower right side, and (4) delayed eruption of lower left canine. Conclusion Dental anomalies have multiple effect on the occlusion as well as on the esthetic. Early diagnosis and intervention and collaboration between the different subspecialty are needed. Clinical significance Pedodontics, orthodontic, restorative, and prosthodontic consultation was taken for the best future proposed treatment that ranges between orthodontics space closure, implants, and esthetic treatment for the peg laterals.
