Amelogenesis Imperfecta -Etiology and Prosthodontic Management

Amelogenesis imperfecta represents a variety of structural abnormalities of enamel that result from some malfunction of the enamel organ. The aim of the treatment is to restore esthetics,masticatory function, increase vertical dimension of occlusion and  reduce  hypersensitivity of teeth. Modern  methods and materials have widened the range of available treatment

Effect of denture wearing on occurrence of fungal isolates in the oral cavity: a pilot study

Objectives: An attempt was made to evaluate effect of denture wearing on occurrence of fungal isolates in the oral cavity before and after complete denture insertion. Method: Twenty five completely edentulous patients were selected; swab samples were collected intraorally before fabrication of complete dentures from labial vestibular area and after complete denture fabrication (one and four days after denture insertion). Further these samples were inoculated and incubated. Results: In nineteen patients no isolate of fungus before denture insertion as well as 4 days after denture insertion was found. In two subject results were false positive (contamination from environment), and in four patients there was increase in growth but not much significant increase of growth of fungal isolates was seen (mild growth of fungus only after denture insertion). One of the major finding of this study was overall occurrence of fungal isolates (before and after denture insertion) in the oral cavity were not significant

The diagnostic role of saliva: a review

As a diagnostic fluid, saliva offers distinctive advantages over serum because it can be collected non-invasively by individuals, even by patient. Does not require special equipment for collection and storage as unlike blood saliva does not clot. Advantageous for person in whom blood drawing is difficult as in obese and haemophilic patient. Whole saliva used for diagnosis of systemic diseases, because it contains serum constituents. These constituents are derived from the local vasculature of the salivary glands and gingival cervicular fluid.This review examines the diagnostic application of saliva for hereditary disorders, autoimmune diseases, malignant and infectious diseases, and endocrine disorders, as well as in the assessment of therapeutic levels of drugs and the monitoring of illicit drug use, and also for forensic evidence and others. . In future we are likely to see the increased utilization of saliva as a diagnostic fluid. As we enter the era of genomic medicine, sialochemistry will play an increasingly important role in the early detection, the monitoring and progression of the systemic and oral diseases

Microstomia in a maxillectomy patient: A prosthetic challenge

The provision of a satisfactory denture in case of reduced stomal inlet has always been a trouble for the patient and a challenge to the prosthodontist. Fabrication of complete and removable partial denture prosthesis requires accurate diagnostic impression and diagnostic casts for the development of custom trays and final impression. The decreased mouth opening, technically called "Microstomia," poses problems in tray selection, impression making, jaw records and denture insertion. The causes for microstomia are numerous, one major cause being the after-effect of radiation therapy. Whatever the cause, the ability to make impressions and jaw records becomes taxing. A variety of impression techniques using modifications in the nature of the tray and impression materials are required. The present case report highlights an innovative and different aspect of impression making and fabrication of an obturator prosthesis for a microstomic patient who underwent maxillectomy
