Mental Nerve Paraesthesia: A Report of Two Cases Associated with Endodontic Etiology

Abstract

Paraesthesia of the mental nerve can occur due to various etiological factors. Rarely, dental infections can cause paraesthesia. However, this article discusses two cases of endodontic etiology in the mental nerve region as a causative factor for paraesthesia. In the first case, the patient had severe pain localized to his right mandible, with numbness of his lower lip. Endodontic treatment led to quick regression and resolution of paraesthesia. In the second case, a patient who was referred for retreatment of a mandibular second premolar infection developed profound paraesthesia in the region of the mental nerve distribution following prior therapy. Possible mechanisms responsible for periapical infection-related paraesthesia are discussed here. CBCT imaging may be useful in the diagnosis and management of such conditions.

Accidental finding of an accessory mental nerve during mandibular fracture reduction

“…In Sri Lankan context, a study done by warmth, cold, burning, aching, prickling, tingling, pin and needle sensation, or numbness as a burning, tickling, or tingling sensation (6). In the case of mental nerve paresthesia there is loss of sensation to the ipsilateral side skin region of the chin and intra oral mucosa (6). Also reduced sensation of the ipsilateral central incisor.…”

The Temporary Mental Nerve Paresthesia as an Outcome of Dentigerous Cyst Removal during Preparation for Dental Implant Placement: A Case Report

“…A mental foramen (AMF) can also be present, along with various nerve fibers (Figu 6]. Possible damage of the mental nerve can be caused by various factors, such as trauma (mandibular fracture); endodontic treatment of mandibular premolars and surgery close to this premolar area (iatrogenic factors (cyst removal)); periapical cyst, abscess, and inflammatory/periapical infections; tumor spread (oral cancer, leukemia, lymphoma (Vincent Sign, tumor spread into the nerve structure)); orthognathic surgery (BSSO-Bilateral Sagittal Split Osteotomy/genioplasty, chin wing approaches); damage to the nerve after abscess drainage; lower lip mucocele removal/labial minor salivary gland retention cyst (nerve fiber damage); local anesthesia administration; compression of the nerve and adjacent tissue pulling; or others [4][5][6][7][8][9][10]. These factors might cause transient or permanent paresthesia.…”

“…Mental nerve paresthesia (MNP) is reported to be a cause of dental treatment (dental implant, trauma, endodontic approaches) in approximately 15-20% of cases. On the other hand, according to the Chai et al study, because of growing interest in the transoral endoscopic thyroidectomy vestibular approach (TOETVA), many studies indicate that because of the following, in order to minimize MN damage, special anatomical landmarks should be used [8][9][10][11].…”

Lower Lip Paresthesia in a Patient With Carious Mandibular Premolar: A Case Report

“…It's crucial to locate the mental foramen precisely for diagnosing and therapeutic treatments. 5 Moreover carefully considered should be the close anatomic vicinity of the mental nerve bundle and the root apex of the lower premolars. It is also well-known that pre-and post-endodontic periapical disease can cause inferior alveolar nerve paraesthesia.…”
