A clinical evaluation of topical application of“LTA”was studied as a treatment for the symptoms of“acute pulpitis”and“acute apical periodontitis, ”and the questionary test for the patient who received the treatment on limited area of the oral cavity was carried out.

The results can be summarized as follows:
1) 87.5% of“acute pulpitis”patients and 64.7% of“acute apical periodontitis”showed improvement of the symptoms (Table 6) .
