Clinical outcomes of a novel flowable calcium silicate cement in equine endodontic treatment

Equine Veterinary Journal, Volume 58, Issue 6, Page 1602-1611, November 2026.
Abstract Background Orthograde endodontic treatment of equine cheek teeth is performed infrequently with variable success rates of obturation with calcium hydroxide paste (CHP). A novel flowable calcium silicate cement (eCSC) formulated for use as an obturation material in equine teeth has demonstrated acceptable canal filling volumes and evidence of ...

Multi‐omics analysis of ion channels expressed by chicken embryo vestibular type I and type II hair cells

Experimental Physiology, Volume 111, Issue 10, Page 4894-4914, 1 October 2026.
Abstract Balance and gaze rely on the rapid and accurate detection and signalling of head movements by vestibular type I and type II hair cells. Signal transduction and transmission involve several types of ion channels, which are acquired progressively during hair cell differentiation and whose identity is known only in part.

Evaluation of apically extruded debris during root canal filling material removal in teeth with external apical root resorption: a comparison of different obturation techniques

BMC Oral Health
Background Root canal retreatment is necessary when initial treatment fails. Nickel-titanium systems help remove filling materials; however, some methods can cause canal content extrusion, resulting in inflammation and delayed healing.
