THE EDITOR'S CORNER

Second molars are victims of neglect. They are not often enough included in the orthodontic strap-up, which may result in their being forced buccally out of the arch or in their impaction; and in losing their influence not only in arch mechanics, but in control of arch form and occlusal plane. Also, they are fairly inaccessible for toothbrushing, because of their distant and incompletely erupted position for so long a time. Therefore, they are subject to decay, a large proportion of which might be avoidable.

Prevention in dentistry is being reemphasized and specific home care of erupting second molars can be a positive part of such a program. This may be a specific use for oral irrigators, such as Water-Pik and Pulsar.

If oral irrigators are prescribed for this and for general oral hygiene, there should be a demonstration model in the orthodontic office, and time should be devoted to instructing patients in their proper use. Demonstration areas and techniques can be developed, so that the process does not become too wet, too frivolous or unproductive. One possible technique for instruction that might be explored is to use air as a substitute for water for most of the demonstration.

To tell a child to use an oral irrigator without instructing him in the specific areas that it is intended to clean, will usually result in failure and discontinued use of a potentially valuable oral hygiene aid.
