Evaluation of early nerve regeneration using a polymeric membrane functionalized with nerve growth factor (NGF) after a crush lesion of the rat mental nerve.

Purpose: The aim of this study was to evaluate mental nerve regeneration in rats after a crush lesion by using a polymeric membrane functionalized with nerve growth factor (NGF).

Materials And Methods: To evaluate the regeneration 1 month after the lesion, electrophysiological recordings of afferent neurograms were associated with a histologic analysis of neurons soma in the trigeminal ganglion using a retrograde fluorescent tracer. Three animal groups were used: uninjured rats (TEM), injured control rats without membrane (CONT), and injured rats with membrane containing NGF.

The lateral pterygoid muscle, a heterogeneous unit implicated in temporomandibular disorder: a literature review.

Based on its anatomical relationships, the lateral pterygoid muscle is strongly linked with the temporomandibular joint (TMJ). It plays a major role in mastication. Embryological, histological, and anatomical knowledge define the lateral pterygoid muscle as a single muscle with a penniform structure.

Neurosensory disturbances of the inferior alveolar nerve: a retrospective study of complaints in a 10-year period.

Purpose: The aim of this study was to evaluate the prevalence of neurosensory disturbances (NSDs) of the inferior alveolar nerve after dental procedures.

Materials And Methods: A retrospective study of patient complaints for transient and permanent NSDs was achieved by means of a 10-year follow-up of claims to a national practitioner insurance company. Claims for 3 different dental procedures were analyzed from 157,292 contracts of insurance recorded during this period.

Spontaneous mandibular fracture in a partially edentulous patient: case report.

This article describes the case of a 78-year-old patient whose mandibular fracture was treated with miniplate osteosynthesis. After initial treatment, panoramic radiography revealed a fracture of the miniplate, and at follow-up, a loosening of the replacement plate. For the dental practitioner, this clinical case highlights the importance of panoramic radiography and occlusal analysis and stabilization for diagnosis of mandibular fracture, evaluation of miniplate fracture and treatment, especially in the absence of trauma.

Immediate and late mandibular fractures after third molar removal.

Purpose: In this retrospective study, we analyzed immediate and late mandibular fractures after impacted lower third molar surgery.

Patients And Methods: One hundred fifty oral and maxillofacial surgeons in the north of- France were questioned about their experience with intraoperative and late mandibular fracture after third molar surgery. Cases were examined clinically and radiographically.
