“…6,37 Most studies have focused on the preoperative risk factors of trigeminal neurosensory disturbances (NSDs). 10,11,33,47 The identification of these risk factors is important because they may allow the phenotyping of patients in the future. This phenotyping is crucial if we wish to improve treatment outcomes.…”

Neurosensory disturbances (NSDs) caused by injury to the trigeminal nerve can affect many aspects of daily life. However, factors affecting the persistence of NSDs in patients with posttraumatic trigeminal neuropathies (PTTNs) remain largely unknown. The identification of such risk factors will allow for the phenotyping of patients with PTTNs, which is crucial for improving treatment strategies. We therefore aimed to identify the prognostic factors of NSD persistence, pain intensity, and quality of life (QoL) in patients with PTTNs and to use these factors to create a prognostic prediction model. We first performed a bivariate analysis using retrospective longitudinal data from 384 patients with NSDs related to posttraumatic injury of the trigeminal nerve (mean follow-up time: 322 6 302 weeks). Bivariate and multivariate analyses were performed. The multivariable prediction model to predict persistent NSDs was able to identify 76.9% of patients with persistent NSDs, with an excellent level of discrimination (area under the receiver operating characteristic curve: 0.84; sensitivity: 81.8%; specificity: 70.0%). Furthermore, neurosensory recovery was significantly associated with sex; injury caused by local anesthesia, extraction, third molar surgery, or endodontic treatment; and the presence of thermal hyperesthesia. Pain intensity and QoL analysis revealed several factors associated with higher pain levels and poorer QoL. Together, our findings may aid in predicting patient prognosis after dental, oral, and maxillofacial surgery and might lead to personalized treatment options and improved patient outcomes.

“…We were able to provide a detailed descriptive study of the distribution of the mental nerve in the lower lip. We did not, however, find comparable studies on the types of distribution and connections of inferior alveolar nerves in the lower lip, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and data in anatomical works are scarce. Previous studies on the inferior alveolar nerve in the lower lip often focus on its relationship with the minor salivary glands.…”

“…This nerve damage can have significant psychoaffective and social consequences. [3][4][5][6][7][8][9][10] Existing studies mostly focus on the relationship between the mental nerve and the minor salivary glands. 11,12 Nevertheless, a detailed and precise knowledge of mental nerve distribution in the lower lip would allow us to understand the nerve map of the lower lip and the recovery or substitution process in the case of damage to the inferior alveolar nerve or its branches in the lower lip.…”

Background: Inferior alveolar nerve damage is one of the most common complications of surgery on the lower third of the face. It can have a significant psychological and social impact, and its evolution varies in terms of the duration and degree of recovery. In the literature, few studies adequately explain this phenomenon. The author therefore aims to establish the anatomical basis of recovery and its variability. Methods: The author studied 60 mental nerves on 30 lips. A total of 25 lips were studied in situ, including five receiving an intraarterial injection of latex, whereas five lips were removed and dissected under transillumination. Results: The author identified three types of intralabial distribution of the mental nerves: type I, absence of connections; type II, connections on the upper third of the lower lip; and type III, connections on the upper, middle, and lower thirds of the lower lip. Some cases also had a dominant side with more numerous fibers and a larger diameter than the contralateral side. Conclusions: Rapid or total recovery after inferior alveolar nerve damage is well known. The author's study showed the nerve map to repair nerve damage, and for the first time, to the author's knowledge, it highlighted the connections between the mental nerves in the lip. Types II and III allow the recovery of labiomental sensation.

“…Furthermore, this study highlights that a definitive diagnosis is often only made following assessment from a number of specialists. The involvement of secondary and tertiary referrals makes the process protracted and potentially financially burdensome (Devine et al, 2017; Lang et al, 2016; Linn et al, 2007). As a result of our findings we suggest that when pain of non‐odontogenic nature is suspected, clinicians: (1) Be knowledgeable about temporomandibular joint and muscle disorders, and somatosensory examination when non‐odontogenic pain is suspected.…”

“…Persistent pain is estimated to affect 5%-24% of endodontic patients, and it is not always clear whether such pain is a true sequela of endodontic treatment, or if it is a persistence of pre-operative pain that was not resolved with root canal treatment (Macrae, 2008;Nixdorf et al, 2010;Philpott et al, 2019;Polycarpou et al, 2005;Vena et al, 2014). Diagnosing such pain is difficult (Aggarwal et al, 2008;Devine et al, 2017Devine et al, , 2018. According to the most recent orofacial pain classification, pain caused by an identifiable trauma to the trigeminal nerve, persisting longer than 3 months, and associated with somatosensory changes is diagnosed as posttraumatic trigeminal neuropathic pain (PTTNP).…”

Objectives: Diagnosis and treatment of non-odontogenic pain is challenging for endodontists. The purpose of the study was to investigate the outcomes of referrals to orofacial pain specialists made for patients with suspected non-odontogenic pain, after evaluation and/or treatment by an endodontist. Materials and Methods:A retrospective review of dental records was conducted for 60 patients referred from a postgraduate endodontic clinic to an orofacial pain clinic.Patient demographics, pain history, endodontic, and orofacial pain diagnoses were collected. Number of visits, length of treatment, and treatments prescribed were recorded. For analysis of outcomes, data pertinent to resolution/persistence of symptoms and patient compliance were analyzed.Results: Thirty-five patients were included in the study. The most frequent pulpal and periapical diagnoses were previously treated (62%) and symptomatic apical periodontitis (72%), respectively. The most common orofacial pain diagnosis was temporomandibular disorder. The average time spent to diagnose and treat the pain was 17 months. Pain reduction varied and was documented for 51% of patients. Indications of non-compliance with orofacial pain appointments and treatments were documented for 66% of patients.Conclusions: Non-odontogenic pain diagnosis and treatment are challenging.Patients may have an increased predilection for developing persistent pain after endodontic treatment and/or have an undiagnosed, chronic orofacial pain condition as a true source of their chief complaint. It may be helpful for endodontists to set expectations of typical treatment times/plans when referring patients for evaluation and treatment of non-odontogenic pain.
