I'm not sure whether the Holidays are when most people like to have their scaling and root planing done. Regardless, that is a pretty good rate of growth. Costs were 24% higher, due to the ramp up of marketing expenses. Stock price has hardly changed. <<``Revenue generated by Arestin(TM) during the fourth quarter was approximately 60% higher than the previous quarter, reflecting the increasing acceptance of the product by the dental community. We are extremely pleased with the progress we are making in marketing Arestin(TM). In our first nine months, we have sold Arestin(TM) to approximately 8,500 dental professionals, a third of our core target market. More than 2,900 of these professionals, or 35% of our customers, have already reordered the product. This is significant given that it takes 4 to 6 months for a dental professional to clearly see the clinical benefit that Arestin(TM) provides to patients. We are committed to significantly growing our customer base during 2002 and beyond, and we look forward to a growing percentage of our customer base reordering Arestin(TM) on a regular basis.'' ``Other highlights during the quarter include continuing progress with the Phase 1 clinical trial for our product candidate for the treatment of mucositis, a severe complication of cancer therapy. We also continued to make progress in advancing our product candidate for bone and tissue regeneration,'' reported Mr. Kishbauch. ``These two products leverage our core competencies in the areas of drug formulation and drug delivery for indications that significantly broaden our market potential beyond periodontal disease, to include oncology, dental implantation and orthopedics.''>> Marc
