Contact stomatitis occurs in up to 10% of the population. Mechanical or chemical irritation, ill-fitting dentures, and dental fillings can induce irritant contact stomatitis. Type I hypersensitivity and type IV hypersensitivity to dental products and foods are frequently responsible for the allergic types of contact stomatitis. We review the causal agents of contact stomatitis, the differential diagnoses, diagnostic testing, and potential treatment.

Jong Chan Kim, In Pyo Hong
Epidermal cysts are intradermal or subcutaneous cystic tumors that frequently occur in the face, scalp, neck, and body trunk. Acquired cases of epidermal cyst commonly occur as a result of various surgical operations, chronic irritation, or trauma, all of which may trigger the occurrence of the invagination of squamous epithelium. A 57-year-old man presented with a palpable mass 7 cm×2 cm in size in the upper lip. The patient had a 3-year history of wearing a denture to restore missing bilateral maxillary central and lateral incisors, accompanied by inflammatory findings on the buccal mucosa due to chronic lip irritation...

The prime requisite of a sound and holistic prosthodontic rehabilitation from both the patient's and clinician's perspective is to be able to satiate the yardsticks of function, retention, aesthetics and comfort to the fullest. It is thereby astoundingly hard to digest that speech being an indispensably significant function of the complete denture prosthesis, is often seen upon as heedless and inconsiderate by the patient. Adaptability in speech pronunciation of complete denture prosthesis is a subjective phenomenon; cannot be predicted to entirety...

Nature provides many interesting examples of adhesive strategies. Of particular note, the protein glue secreted by marine mussels delivers high adhesion in wet and dynamic environments owing to existence of catechol moieties. As such, this study focuses on denture fixatives, where a non-zinc-containing commercial-based formulation has been judiciously modified by a biomimetic catechol-inspired polymer, poly(3,4-dihydroxystyrene/styrene-alt-maleic acid) in a quest to modulate adhesive performance. In vitro studies, in a lap-shear configuration, revealed that the catechol-modified components were able to enhance adhesion to both the denture base and hydrated, functional oral tissue mimic, with the resulting mode of failure prominently being adhesive rather than cohesive...

PURPOSE: The aim of this study was to determine the influence of long base lengths of a fixed partial denture (FPD) to rotational resistance with variation of vertical wall angulation. MATERIALS AND METHODS: Trigonometric calculations were done to determine the maximum wall angle needed to resist rotational displacement of an experimental-FPD model in 2-dimensional plane. The maximum wall angle calculation determines the greatest taper that resists rotation. Two different axes of rotation were used to test this model with five vertical abutment heights of 3-, 3...

AIM: Different biomaterials and techniques have been introduced in the field of prosthetic dentistry with the purpose of replacement and rehabilitation of the edentulous areas. Due to their shorter setting time, the light-activated restorative and prosthetic materials have the capability of releasing few amount of cytotoxic materials in the oral cavity. Polymer materials [urethane dimethacrylate (UDMA) and bis-acryl] are assumed to have high mechanical properties. Polymethyl methacrylate (PMMA) offers numerous advantages of being highly esthetic in nature and at the same time being cost-effective...
