The clinical spectruni of epidermolysis bullosa acquisita(EBA) is much broader than originally thought. Although the full extent of the clinical presenation is still being defined, it is now known that EBA include the followings: a non-inflammatory mechanobullous condition equating wit,h classical EBA; an inflammatory vesiculosullous eruption mimicking bullous pernphigoid; and a mucosal-centered disease with sarring similar to cicatricial pemphigoid. Among the nine cases of EBA, aged between 34 to 70 year-old, seen in recent years, three patients had mechanobullous lesions with skin fragilities and scarrings; three patients had inflammatory bullous eruptions, and three other patient had combined features of mechanobullous/inflammatory bullous lesions. Mucous membrane lesions were recognized in sex cases, and the rnos! frequent site of involvement was the oral mucosae. According to observations of these patients episodes of inflammatory bullous eruptions appeared to be present in seven cases and have been considered as early sympoms of the disease. It has been noted, however, that in two cases lesions develop d as an non-inflammatory mechanobullous from thonset. Based on the ability of EBA to mimick bullous pemphigoid or cicatricial pernphogoid and the fact that such cases have perhaps been missed, we feel EBA is more common than past literature has suggested.

STATEMENT OF PROBLEM: The residual monomer of denture base materials causes hypersensitivity on oral mucosa and intereferes with the mechanical properties of the cured resin. The amount of residual monomer is influenced by materials, curing cycle, processing method, and etc. PURPOSE: The aim of this study was to investigate the residual methyl methacrylate(MMA) content of injection molded denture base polymer, and to compare this with the self-cured resin and the conventional compression molded heat-cured resin. MATERIALS AND METHODS: Disc shaped test specimens (50mm in diameter and 3mm thick) were prepared in a conventional flasking technique with gypsum molding. One autopolymerized denture base resins (Vertex SC. Dentimex. Netherlands) and two heat-cured denture base resins (Vertex RS. Dentimex. Netherlands, Ivocap. Ivoclar Vivadent, USA) were used. The three types of specimens were processed according to the manufacturer's instruction. After polymerization, all specimens were stored in the dark at room emperature for 7 days. There were 10 specimens in each of the test groups. 3-mm twist drills were used to obtain the resin samples and 650mg of the drilled sample were collected for each estimation. Gas chromatography (Agillent 6890 Plus Gas Chromatograph, Agillent Co, USA) was used to determine the residual MMA content of 10 test specimens of each three types of polymer. RESULTS: The residual monomer content of injection molded denture base resins was 1.057+/- 0.141%. The residual monomer content of injection molded denture base resins was higher than that of compression molded heat cured resin (0.867+/-0.169%). However, there was no statistical significant difference between two groups (p > 0.01). The level of residual monomer in self cured resin(3.675+/-0.791) was higher than those of injection molded and compression molded heat cured resins (p<0.01). CONCLUSION: With respect to ISO specification pass/fail test (2.2% mass fraction) of residual monomer, injection molding technique(1.057+/-0.141%) is a clinicaly useful and safe technique in terms of residual monomer.
