Context:Desensitizers are used to reduce dentin hypersensitivity. They affect the surface texture of prepared dentin and may alter the retention of fixed restorations.Aims:The aim was to evaluate the effect of dentin desensitizers on the retention of complete cast metal crowns luted with glass ionomer cement.Subjects and Methods:Fifty freshly extracted human premolars were subjected to standardized tooth preparation (20° total convergence, 4 mm axial height) with a computer numerically controlled machine. Individual cast metal crowns were fabricated from a base metal alloy. Dentin desensitizers included none (control), a glutaraldehyde (GLU) based primer (Gluma desensitizer), casein phosphopeptide (CPP)-amorphous calcium phosphate (ACP) (GC Mousse), erbium, chromium: YSGG laser (Waterlase MD Turbo, Biolase) and Pro-Argin (Colgate Sensitive Pro-Relief desensitizing polishing paste). After desensitization, crowns were luted with glass ionomer cement and kept for 48 h at 37°C in 100% relative humidity. The samples were tested using a universal testing machine by applying a load at a crosshead speed of 0.5 mm/min.Statistical Analysis Used:Statistical analysis included One-way ANOVA, followed by the Scheffe post-hoc test with P < 0.05.Results:All dentin desensitizers showed significantly different values: Pro-Argin (4.10 Megapascals [Mpa]) < CPP-ACP (4.01 mpa) < GLU based primer (3.87 Mpa) < Virgin dentin (3.65 Mpa) < LASER (3.37 Mpa).Conclusions:On comparing the effect of prepared virgin dentin, GLU based primer, CPP-ACP, LASER and Pro-Argin on the retention of complete cast metal crowns luted with glass ionomer cement on prepared teeth, it can be concluded that Pro-Argin and CPP-ACP showed the best retention in this in vitro study.

Replacing a missing tooth in a maxillary anterior esthetic zone displaying a Seibert's class III ridge defect is a big challenge in the field of perioesthetics. In order to achieve maximum esthetics, form and function, an ideal pontic should have a natural emergence profile and support the labial soft tissue as well as the adjacent papillae. This is of paramount importance, especially if the patient has a high smile line. Augmentation protocols differ based on the treatment plan for implants or fixed prosthesis. The most popular techniques for soft tissue ridge augmentation for Seibert's Class III ridge defects include the roll technique, the wedge technique and the pouch technique among others. This article presents a case of an 18-year-old female patient with a challenging Seibert's Class III ridge defect treated for pontic site development using a combination of the pouch and the roll technique followed by a fixed prosthesis with ovate pontics.

Discontinuity defects in the mandible cause various ill effects like imbalance in the muscles of the lower face, facial disfigurement, restriction of tongue causing alteration of speech and altered salivation. It leads to decreased mandibular function by deviation of the residual segment toward the surgical side and affects masticatory function adversely. Postoperative care and prosthodontic rehabilitation required in hemimandibulectomy patients is interdisciplinary including surgical management, prosthodontic treatment, speech therapy, oral physiotherapy and psychologic care. It is difficult to provide a functional, retentive and stable prosthesis to such patients. In the described case report, a hemimandibulectomy patient was successfully rehabilitated by providing maxillary and mandibular overdentures with intraradicular ball attachments on natural teeth. This treatment option was a simple, convenient and economical method of enhancing denture retention and stability; and providing security and comfort to the patient.
