The genus Ophiostoma includes numerous species of primarily insect-vectored, wood-staining fungi. Several anamorph genera that differ in their micronematous or macronematous conidiogenous cells have been associated with Ophiostoma species. Among the former group, Sporothrix is associated with many species and is characterized by conidiogenous cells that arise laterally or terminally from any pl...

Mangoes account for approximately half of all tropical fruits produced worldwide. India is the largest mango producer, accounting for about half of the global mango production. But, less than five per cent of the produced mangoes are processed and mango pulp is the main export product both in terms of volume and value. Contract system is the major marketing system in the supply of mangoes becau...

Materials and Methods: The sample consists of 100 patients, 45 males and 55 females, aged 13–22 years. A translated pre-tested questionnaire [psychosocial impact of dental aesthetics questionnaire PIDAQ] was used to assess the subjects’ social and psychological impact by their occlusal irregularities. The actual severity of malocclusion was determined, using the dental aesthetic index (DAI) on ...

Dens invaginatus (dens in dente) is a rare malformation with a widely varied morphology. An unusual presentation of a type III dens invaginatus affecting a conical shaped permanent lateral incisor in an 8-year-old female patient is reported. The presence of a pulp stone and a periapical radiolucency further added onto the complexity of the case. The etiology, pathophysiology, association with o...

STATEMENT OF PROBLEM Fabrication of indirect complete crowns that are in occlusal harmony upon insertion remains a problem in restorative dentistry, and dental stone cast expansion may play a role. PURPOSE This 3-part investigation compared occlusal contacts in a simulated patient with a harmonious occlusion with centric occlusion equal to maximum intercuspation (CO=MI) and an inharmonious oc...

Dental calculus, a type of stone formed even under normal conditions, plays an important role in some periodontal diseases. Deposition of dental calculus follows plaque formation, and the variations in the degree of calcification reflect the changes in environment and form of its lamellar structure[1]. Dental plaque is composed of rods, cocci and filamentous bacteria[2], and these morphological...

BACKGROUND Colour degradation is a major problem in maxillofacial silicone elastomers. Recent studies have focused on colour stability and the mechanical properties of the silicone elastomers. A colour match is also essential for the acceptance of the prosthesis by the patient. The aim of this study is to assess the colour degradation of the silicone elastomer after being moulded in different c...

THIS report presents a method of determining the dimensional changes in gypsum dental products, which avoids the disadvantages of previous methods and which provides extreme sensitivity. As part of the program of research on the gypsum products used in dentistry, a preliminary study was made of various physical properties. This study, which included strength, thermal expansion, setting expansio...

THE JOURNAL OF PROSTHETIC DENTISTRY 113 The most commonly used molds in the subspecialty of facial prosthetics are made of dental plaster and stone. The molds’ material advantages are that they are economical, time efficient, and easy to fabricate. The disadvantages are wear with repeated use for prosthesis fabrication, they must be thoroughly dry before processing with moisture sensitive facia...
