A simple technique for isolation in inaccessible areas of oral cavity.

Introduction: Isolation or maintenance of clean, visible, dry field is an absolute necessity for any dental or surgical procedure. Apart from improvement in visibility, accessibility, and appropriately directed isolation instrument should also allow operator to work simultaneously for long duration. Methods: We used readily available disposable 18 gauge needle which can be easily and snuggly attached to stainless steel suction cannula. This method/ attachment provided better accessibility with minimal hindrance, i.e. because of small size it allowed suctioning and instrumentation in the limited surgical field to proceed simultaneously which was never possible before by using other methods. This method can be used in various procedures (periapical surgeries, visualization and retrieval of fractured root pieces). Conclusions: Simultaneous visibility and accessibility is key goal of this technique and which can be used to improve patient care.

The current status of laser applications in prosthodontics.

Lasers were introduced into the field of clinical dentistry with the hope of overcoming some of the drawbacks posed by the conventional methods of dental procedures. Since its first experiment for dental application in the 1960s, the use of laser has increased rapidly in the last couple of decades. At present, wide varieties of procedures are carried out using lasers. The aim of this review is to describe the current and emerging applications for lasers in prosthetic dentistry. Used in conjunction with or as a replacement for traditional methods, it is observed that specific laser technologies are becoming an essential component of contemporary dental practice over a decade.

Saliva and its importance in complete denture prosthodontics.

Saliva is a complex fluid composed of secretions from salivary glands and gingival crevicular fluid. The oral cavity is a moist environment; a film of fluid called saliva constantly coats its inner surface and occupies its space between the lining oral mucosa and teeth, whose important role is maintaining the well being of the mouth. Saliva plays a critical role in the maintenance of oral and dental health. Saliva is most valuable oral fluid that is taken for granted. Knowledge of the salivary system and saliva is essential for evaluating prosthodontic problems and for educating patients in what to expect in this phase of denture use.
