Contrasting Responses Following Transverse Root Fractures in Two Maxillary Central Incisors: (a) Marginal Breakdown With Superimposed Infection and (b) Transient Internal Surface and Tunnelling Resorption. A Case Report of Management With a 34‐Year 9‐Month Follow‐Up

Dental Traumatology, EarlyView.
ABSTRACT An example of contrasting responses in two root fractured teeth in a 16‐year‐old male seriously injured in a hit‐and‐run motor accident is documented over a 34‐year 9‐month period. Extended non‐surgical endodontic management was necessary for one of the root‐fractured central incisors that had developed an infective marginal breakdown, and by ...

Microbial Loads in Traumatized Immature Teeth and Their Impact on the Treatment Outcomes of Regenerative Endodontic Treatment: A Randomized Clinical Trial Comparing Chlorhexidine and Calcium Hydroxide

Dental Traumatology, EarlyView.
ABSTRACT Introduction Regenerative endodontic treatment (RET) aims to promote root maturation in necrotic immature teeth, where effective microbial disinfection is crucial for treatment success. This study evaluated the effect of calcium hydroxide (CH) and 2% chlorhexidine gluconate (CHD) as intracanal medicaments and their impact on bacterial loads ...

Optical signal recording of cellular activity in optogenetic stimulation of human pulp dental cells using a twin-core fiber-based Mach-Zehnder interferometer biosensor [PDF]

arXiv
This paper introduces an innovative two-core fiber (TCF) optic sensor employing a Mach-Zehnder interferometer (MZI) to monitor the optogenetic response of light-sensitive human dental pulp stem cells (hDPSCs). The in-fiber MZI, formed using a segment of TCF optic, detects refractive index (RI) changes in the surrounding medium.
