Aim: The aim of this study is to assess the surface roughness and shear bond characteristics of pol-ether-ether-ketone after different surface treatments. Setting and Design: An in vitro, prospective. Materials and Methods: One hundred and twenty disc-shaped samples of 10 mm diameter and 2 mm thickness were milled and subjected to following surface treatments: 110 μm alumina particles, 98% concentrated sulfuric acid, and 10–20 μm synthetic diamond particles. Surface characteristics of treated sample were studied under SEM with ×500 and ×1000 magnification. Shear bond strength (SBS) with composite resin discs embedded in acrylic blocks after luting with self-etch resin cement and resin-modified glass ionomer cement (RMGIC) was evaluated using the universal testing machine (Instron®, Massachusetts U. S. A). Statistical Analysis Used: The data collected were evaluated using the Analysis of variance and Tukey's honest significant difference post hoc test. Results: Highest SBS and SR were noted with self-etch resin cement in the given order: 98% sulfuric acid (2.106 ± 0.186 μm), followed by alumina particles (1.706 ± 0.160 μm) and synthetic diamond particles (1.101 ± 0.167 μm). Conclusion: The SBS of self-etch resin cement was higher compared to RMGIC for all three surface treatments done on test samples. Hundred percent samples treated by all three surface treatment methods showed mixed type of failure.

Ectodermal dysplasia (ED) is a hereditary disorder characterized by abnormal development of two or more embryonic ectodermal structures such as skin, nails, teeth, hair, eyes, and sweat glands. The main oral manifestations of ED include oligodontia, malformed teeth and, deficient alveolar ridges. Inheritance of ED is X-linked and expressed typically in males. This case report explains a multidisciplinary treatment of a 16-year-old adolescent suffering from ED with underdeveloped premaxilla, underdeveloped alveolar ridges, retained deciduous teeth, and thick fibrous frenal attachment. Prosthetics rehabilitation was done using removable cast partial dentures with lip support. It also enumerates the important role of a multidisciplinary approach in dental treatment, helping the patient’s healthy transition from childhood to adulthood. Dental professionals should be able to identify the oral features of ED and provide proper oral care (as early as 3–4 years) to restore the oral functional demands and esthetics.
