“…In a posterior study, Przystańska and Bruska [18] confirmed the presence of the mylohyoid nerve, sublingual artery, and accompanying vessels in these foramina through histological examination. Abdar-Esfahani and Mehdizade [19] carried out a study on mandibular anterior nutrient canals using periapical radiography in relation to hypertension. The incidence of anterior nutrient canals was 37.5 % in patients with hypertension and 53.1 % in subjects without hypertension, but the difference was not statistically significant.…”

Objective This study aimed to radiographically assess the prevalence and location of accessory foramina in the human mandible using helical computed tomography (CT) images and three-dimensional reconstructions. Methods Helical CT images from 24 males and 22 females aged 66-88 years (mean age: 73.7 ± 5.3 years) were observed. Each image was assessed in the three anatomical planes, and three-dimensional reconstructions were performed with Amira 5.6 software. Results All subjects (n = 46) presented at least one accessory foramina. A lingual foramen was the most frequently observed foramen and present in 96 % (n = 44) of subjects. Mandibular anterior nutrient canals were clearly observed in 72 % (n = 33) of subjects (71 %, n = 17, of males; 73 %, n = 16, of females). A retromolar foramen was present in 17 % (n = 8) of subjects (21 %, n = 5, of males; 14 %, n = 3, of females). A double mental foramen (DMF) was present in only one subject (2 %). Fifty percent (n = 23) of subjects presented one or more inferior retromental foramen (IRF). No significant correlations were observed between prevalences of accessory foramina and sex. Conclusions The lingual foramen can be considered a constant finding, and mandibular anterior nutrient canal foramina and IRF were present in the majority of subjects.Retromolar foramina and DMF were less common but can be associated with anesthetic failures and oral surgery complications. Three-dimensional reconstructions provided better understanding of the locations of foramina and their interrelations with the anatomy of the jaw.

Prevalence of nutrient canals in mandibular anterior intra-oral periapical radiographs (IOPARS) in patients with chronic systemic diseases – a cross-sectional study

Nutrient canals (NCs) are passages containing neurovascular bundles (blood vessels, lymph vessels, and nerves). Best visualized on mandibular anterior intraoral periapical radiographs (IOPAR), their presence is usually associated with underlying pathological such as diabetes mellitus (DM), hypertension (HTN), advanced periodontitis, calcium deficiency, tuberculosis, and disuse atrophy. This study aimed to (a) evaluate NC prevalence in patients with DM, HTN, and chronic periodontitis and (b) correlate the detection of NCs as an important preliminary screening tool for inherent systemic diseases like DM, HTN, and chronic periodontitis and as an investigative clue in age and gender determination. This cross-sectional study was conducted on 200 subjects. Patients with complaints of pain in the mandibular anterior teeth, deep dentinal caries, abrasion, and attrition were subjected to IOPAR of the mandibular anterior teeth region to assess NCs. An increased frequency of NCs in DM (84%), HTN (66%), and periodontitis (52%) with a significant p-value was observed. Most NCs were seen beyond the root apex (72.4%). A notable association between the duration of disease and the presence of NCs in the diabetic and hypertensive cohorts (p-value 0.047 & 0.012, respectively) was observed. However, we could not establish any association between the prevalence of nutrient canals with age and gender. Our study suggested that a higher frequency of NCs on mandibular anterior IOPAR may be employed as an ancillary screening and investigative support in underlying systemic disorders.

Background: Nutrient canals (NCs) are radiolucencies in the bone that transit blood vessels and nerves. Aim: To use cone beam computed tomography (CBCT) to assess the incidence, diameter, and location of NC in healthy and periodontal disease patients and correlate it with the extent of alveolar bone loss. Materials and Methodology: About 200 CBCTs (100 healthy and 100 with periodontal disease) were selected and analyzed. The prevalence, diameter, and location of the NCs were comparatively evaluated between the two groups. The frequency and diameter of the canals were also correlated with the severity of bone loss, age, and gender. Results: Subjects in group II had a significantly greater frequency of NCs (P = 0.0001). NCs in group II had a larger mean diameter. The NCs were nearer to the alveolar crest in group II (16.70 ± 6.31 mm) than in group I (18.08 ± 5.72 mm). Their frequency was significantly greater when the bone loss was greater than two-thirds of the root length (P = 0.043). Conclusion: In patients with periodontal diseases, the incidence and diameter of NCs were higher and correlated positively with the extent of bone loss.
