A study of water flow efficiency in dental air/water syringe tips after repeated chemiclave sterilization.

In response to the need for dental office asepsis, many practitioners sterilize dental air/water syringe tips for each patient. It is hypothesized that repeated sterilization would lead to internal corrosion restricting the water flow. This study was conducted to evaluate consistency of water flow in a series of dental air/water syringe tips after multiple cycles of Chemiclave sterilization. An apparatus was constructed to deliver water at the same pressure and flow to each syringe tip. The flow rates between tips were significantly different (P < .001). Average water flow, in grams per minute, was determined by ten repeat trials for each tip. The tips were retested after 1, 5, and 25 cycles of Chemiclave sterilization. None of tips showed a decrease in water flow efficiency after repeated sterilization cycles. No difference in ability to remove etchant from enamel and dentin could be demonstrated using a 10-second wash.

A treatment need index: a pilot study.

The traditional caries index, DMF, provides inadequate information to assess dental treatment needs of a community. Dental health planners are often called upon to estimate the treatment needs, costs, time and personnel required for a proposed programme. A treatment needs index (TNI) is presented which provides important data for dental health planning. The index defines seven basic levels of treatment: (0) no treatment needed; (1) preventive treatment; (2) fissure sealants; (3) initial conservative restorations; (4) moderate conservative restorations; (5) advanced conservative restorations; and (6) radical treatment, including pulp therapy, prosthetic restorations and extractions. A pilot study and an example comparing data of both DMF and TNI demonstrates the values of the latter index. The Treatment Needs Index provides a more accurate description of caries severity and extent than does the traditional DMF index, and can be used to estimate the time required to treat a community.

Pediatric infection with the human immunodeficiency virus.

While rates of infection with the HIV virus are decreasing, the number of children infected continues to increase. There are multiple implications for the practicing pediatric dentist. Many of these children will seek or be referred by other health care providers for treatment of resulting oral pathology. Dentists must be prepared to provide dental services to the HIV-infected child.

Dental management of long-term amyotrophic lateral sclerosis: case report.

Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease. Methods of dental treatment of a young male patient with ALS are presented. This case is unusual in several respects: the early age of onset, the long survival time, and the period of time in which the case was followed in our dental clinic. Aspects of ALS which are of concern to dentistry, as related to clinical care and strategies for effective oral health delivery, are presented.

Pediatric infection with the human immunodeficiency virus (HIV): head, neck, and oral manifestations.

The increasing incidence of HIV infection in the pediatric population is of concern for the practicing dentist. Long incubation periods of the virus, combined with difficulty in detection, results in many undiagnosed cases of prenatal and natal infections with HIV. As a result, many dentists will unknowingly treat HIV-positive children. This article presents most common features of pediatric HIV infection, placing special emphasis on manifestations which affect the head, neck, and oral tissues.

Appliance therapy for chronic drooling in a patient with mental retardation.

Multiple physical impairments are associated with chronic drooling. This case illustrates the use of a simple appliance to align the patient's lip to provide opportunity for a lip seal when swallowing or at rest in a patient with a Class II malocclusion. The appliance resulted in a significant decrease in drooling in this patient.
