Is there a "safety zone" in the mandibular premolar region where damage to the mental nerve can be avoided if periapical extrusion occurs? [PDF]

, 2010
The mandibular premolars are located close to the mental foramina (Fig. 1). As such, various events affecting these teeth, such as odontogenic infection1 and orthodontic, endodontic, periodontal or surgical misadventure, may result in neurosensory ...

Mandibular Premolar Impaction [PDF]

Scholarly Research Exchange, 2009
Literature specific to impacted premolars is not extensive despite the fact that mandibular 2nd premolars alone account for 2.4% of dental impactions. The purpose of this paper is to describe the radical approach (extraction) of a transversally impacted 2nd premolar in the mandible through a lingual approach due to its peculiar position presuming it ...

An Innovative “Tooth‐On‐Chip” Microfluidic Device Emulating the Structure and Physiology of the Dental Pulp Tissue

Advanced Healthcare Materials, EarlyView.
This work presents a “tooth‐on‐chip” device that mimics dental pulp tissue. By co‐culturing key cell types, it recreates vascular networks, stem cell niches, the odontoblast/dentine interface, and trigeminal innervation. This innovative platform provides a unique model of dental pulp structure and physiology, with significant potential for accelerating
