Abstract
Purpose
At present, the real cause of PPP is not clear and neither is the appropriate therapy. In this study, I tried to cure PPP by differentia] dental approach by means of Bi-Digital O-Ring Test.
Subjects and Method
The first patient was a fifty-five-year-old female suffering from intractable PPP for about six months. For this ailment, although no efficacy was shown, steroid ointment and PUVA-Bath therapy were used. The dental treatment for this patient was to remove the dental alloys that were suggested as allergen by patch test and replace them with gold alloys that were adequate for the lesion by Bi-Digital O-Ring Test (BDORT). The second patient was a fifty-nine-year- old male suffering from intractable PPP for about two years. For this ailment, although no efficacy was show, steroid ointment therapy was used. The medical examinations did not show any abnormality. The dental treatment for this patient was occlusional therapy by means of BDORT.
Results and Discussion
Both treatments showed the excellent result. At present, the real cause of PPP is not clear and neither is the appropriate therapy. However, metal allergy and malocclusion may be important causes of this ailment. BDORT may be very useful for determining the appropriate dental materials and the occlusal situation.
Conclusion
The affect of not only dental material allergy but also occlusal situation on this ailment should be studied. In order to decide the appropriate dental materials and the occlusal situation, BDORT may be very available.
