Qualitative surface roughness of lithium disilicate endo-crown for pulpotomized primary molars.

Rehabilitation of pulpotomized primary molars with an appropriate restoration is essential for recovering function and safeguarding the durability of the treatment. This study aimed to assess and compare the surface roughness of stainless steel (ST) crowns, zirconia (ZR) crowns, fiberglass (FG) crowns, and lithium disilicate (LD) endo-crowns as a restoration for pulpotomized primary molars also, evaluating the surface roughness of their antagonists. Sixty pulpotomized primary mandibular first molars were used for qualitative surface roughness evaluation and divided into four groups (n = 15/group) according to the crown type (group-ST, group-ZR, group-FG, group-LD).

Evaluation of new bioceramic endodontic sealers: An in vitro study.

Background: The biophysical properties of root canal sealers (RCSs) positively affect the success of endodontic treatment. It is important to ensure an impermeable apical seal after the thorough eradication of the infection. Since bioceramic sealers release bioactive and concomitantly biocompatible products after setting, chemical bonding to dentin and favorable healing is achieved.
