Periodontal Repair on Intrabony Defects treated with BBP(R) / 대한치주과학회지

The ultimate goal of periodontal disease therapy is to promote the regeneration of lost periodontal tissue, there have been many attempts to develop a method to achieve this goal, but none of them was completely successful. The purpose of this study was to compare the effects of treatment using BBP(R) with control treated by only modified Widman flap. 22 intrabony defects from 12 patients with chronic periodontitis were used for this study, 10 sites of them were treated with BBP(R) as experimental group and 12 site were treated by only modified Widman flap as control group. Clinical parameters including probing depth, gingival recession, bone probing depth and loss of attachment were recorded at 6 months later, and the significance of the changes was statistically analyzed. The results are as follows: 1. Probing depth of control(delta2.7+/-1.3mm) and experimental group(delta3.6+/-1.8mm) weres reduced with statistically significance(P<0.05), but this changes were not different between the two experiment, control group with statistically significance. 2. Gingival recession showed statistically significant increase in control group(delta2.1+/-1.2mm)(P<0.05), but not in experimental group(delta0.5+/-0.7mm), and this changes were different between the two experiment, control group with statistically significance(P<0.05). 3. Bone probing depth showed statistically significant decrease in experimental group(delta2.9+/-1.0mm)(P<0.05), but not in control group(delta1.1+/-1.4mm), and this changes were different between the two experiment, control group with statistically significance(P<0.05). 4. Loss of attachment showed statistically significant decrease in experimental group(delta3.1+/-1.7mm), but not in control group(delta0.6+/-1.2mm), and this changes were different between the two experiment, control group with statistically significance(P<0.05) On the basis of these results, treatment using BBP(R) improves the probing depth, bone probing depth and loss of attachment in intrabony defects.

A Case of Epidermal Nevus Syndrome Associated with Morning Glory Syndrome and Intestinal Pseudoobstruction / 대한피부과학회지

Epidermal nevus syndrome is defined as the association of epidermal nevi with abnormalities of the other organ systems, and is regarded as one of the neurocutaneous syndromes. However, till now, epiderrnal nevus syndromi has not been reported with either Morning glory syndrome or intestinal pseudoobstruction. We experienced a case of a 7-year old rnale who had had multiple epidermal nevi on the scalp and forehead and solitary larg cafeau lait spot on his chest since birth. He had histories of failure to thrive and mental retardation, but no seizures. He also had histories of frequent diarrhea and abdominal distension. Physical examination showed abnormalities of the skin, teeth, and Morning glory syndrome of both oplic discs. Colon study, small bowel series and biopsy showed intestinal pseudoobstruction. Skeletal survey revealed a difference between the left upper extremity and the right one.
