Clinical Evaluation of Maneuverability and Durability of Titanium Nitride-coated Preformed Crown on Primary Molar Teeth: A Randomized Controlled Trial.

Background: The management of multisurface carious primary molar is challenging. Currently, the ideal choice for the management of extensive multi-surface carious primary molar is the placement of a preformed stainlesssteel crown (SSC)/preformed zirconia crown. Unfortunately, conventional preformed SSCs are frequently refused by parents for esthetic reasons, while the preformed zirconia crown has its own disadvantages like high cost and excessive tooth preparation.

Immunohistochemical study of alpha-smooth muscle actin in odontogenic cysts and tumors.

Context: Myofibroblasts (MFs) are fibroblasts with smooth muscle-like features characterized by the presence of a contractile apparatus. Alpha-smooth muscle actin (α-SMA) is the actin isoform that predominates within vascular smooth muscle cells and plays an important role in fibrogenesis. MFs are metabolically and morphologically distinctive fibroblasts expressing α-SMA, and their activation plays a key role in development of the fibrotic response.
