The excited-state intramolecular proton transfer tautomerism reaction of 6-methyl-4-hydroxy pyri-midine monomers and dimmers was investigated by the ab initio method with the self-consistent reaction field with Tomas's polarized continuum mode and CIS theories at HF level on the basis of 6-311+G* and 6-31G basis set. By studying the potential energy surface, it was found that the monomer's ground-state proton transfer process together with the excited-state proton transfer process is a molecular system of four energy level, but dimmers were not, which can be used to explain the fact that UV-visible absorption and fluorescence spectra of monomer and dimers all corresponded to quinoid.

Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.
