Evaluation of dimensional changes in EndoSeal mineral trioxide aggregate and AH Plus sealers using micro-computed tomography imaging.

Background: Optimal dimensional stability is required for successful root canal treatment. A sealant called EndoSeal mineral trioxide aggregate (MTA) was recently introduced to the market due to its favorable physical and chemical properties. On the other hand, AH Plus (AHP) is considered the gold-standard seal.

Cone Beam Computed Tomography (CBCT) findings of fungal sinusitis in post COVID-19 patient: A case report.

Background: Fungal infections of the paranasal sinus are increasingly recognized in both normal and immunocompromised individuals. It is necessary to distinguish invasive diseases from the non- invasive as the result and prognosis of sinus treatment different in each one. CBCT imaging could help us in this regard.

Associations among palatal impaction of canine, sella turcica bridging, and ponticulus posticus (atlas arcuate foramen).

Introduction: The palatal impaction of canine (PIC) can be predicted by some head and neck skeletal anomalies or variants. Since studies on this regard (especially vertebral anomalies) are scarce, this study was conducted.

Methods: This case-control study was done on 46 PIC orthodontic patients (34 females, 12 males) and 46 control orthodontic patients (36 females, 10 males).
