Bonding amalgam to tooth structure: a scanning electron microscope study
Scherer, W; Penugonda, B; Allen, K; Ruiz, M; Poveda, C
The purpose of this scanning electron microscope study was to observe the interface between dentin and amalgam utilizing various adhesive resin cements. The adhesive resin materials used in this study were Imperva Dual, Geristore, and Panavia. The scanning electron micrographs revealed that bonds were established between amalgam, adhesive resins, and dentin

Root canal filling materials for primary teeth: a review of the literature
Kubota, K; Golden, B E; Penugonda, B
In summary, there is no known ideal root canal filling material for primary teeth. The closest to the ideal appears to be a calcium hydroxide-iodoform mixture. More histopathologic studies as well as long-term clinical studies are needed on this material

Profilometer, SEM, and visual assessment of porcelain polishing methods
Goldstein, G R; Barnhard, B R; Penugonda, B
Research has indicated that polishing ground porcelain is essential to control the wear of opposing occlusal surfaces and reduce the inflammation of contacted soft tissue. Five popular methods for polishing porcelain were evaluated by use of a profilometer, SEM, and normal vision. Seventy disks, 35 Biobond disks and 35 Ceramco disks, were roughened with a green stone and polished with one of the methods according to the manufacturers' directions. Brasseler, Dedeco, Dentsply, and Shofu porcelain polishing systems were suitable for restoring ground porcelain. However, clinical evaluations correlated to the profilometer and SEM readings revealed that the Brasseler system was superior for polishing Ceramco porcelain whereas the Den-Mat system was unacceptable

Mounting a maxillary cast transversely horizontal and constructing a plane of occlusion bilaterally symmetrical
Zelnigher, J; Ravinett, S; Penugonda, B; Kriser, D B
This article discusses a technique for mounting a maxillary cast to any semiadjustable articulator using the dentaplane. The dentaplane is a precision device that divides the articulator space into approximately equal upper and lower halves when attached to the lower member. The dentaplane mounts the maxillary cast with a transverse orientation that replicates conditions in a patient's head
