Objective: To determine the mean distance of mandibular incisive canal from the mental foramen in patients reporting to a tertiary care centre using Cone Beam Computerized Tomography for placement of dental implants in the anterior/interforaminal region. Study Design: Cross-sectional study. Place and Duration of Study: Department of Prosthodontics, Foundation University College of Dentistry Rawalpindi, Jun to Nov 2019. Methodology: A total of 70 patients participated between the age of 20-45 years. Cone Beam Computerized Tomography (the investigation was carried out and measurements of the mandibular incisive canal from mental foramen were recorded with the help of measuring tools in the software and noted down on the proforma. Data were analyzed using SPSS-20. Results: The number of patients selected for this study was 70. Out of these 70 patients, 33 (47.1%) were males and 37 (52.9%) were females. The mean age of patients in this study was 36.31 ± 6.38 years. The mean distance/extension of the mandibular incisive canal from left mental foramen and right mental foramen in all patients was recorded to be 14.49 ± 6.31 mm and 14.97 ± 7.10 mm respectively. Conclusion: Within the limitations of this study, it is concluded that a maximum distance of 22mm of the incisive canal from the mental foramen was observed using cone-beam computerized tomography.

Abstract Introduction: Anatomically, the incisive canals start on the nasal fossa floor, close to the septum, and open at the incisive foramen of the maxillary palatine process. The nasopalatine nerve passes through the incisive foramen as well as the septal artery and the sphenopalatine vein. Also, there may be accessory canals. Typically, the incisive foramen has two incisive canals. This work aimed to analyze the morphology and morphometry of the foramen and incisive canals in the macerated cephalic skeletons. Material and methods: For this purpose, we selected 150 samples of adult individuals, with no distinctions of sex and ethnicity. We analyzed the frequency of incisive canals in the foramen was analyzed as well the area, diameter, and communications of incisive canals with the fossa and nasal cavity. Results: The cephalic analysis results showed that most incisive foramina have at least two canals that communicate the nasal cavity with the oral cavity. The right-side canal had an average of 1.975mm² in area and 1.281mm in diameter. Also, the left-side canal had an average of 1.468mm² in area and 1.182mm in diameter. The average area and total diameter of the incisive foramen were 8.148mm² and 3.101mm, respectively.Conclusion: Hence, understanding anatomy and its variations is essential for clinical applications, as it may alter surgical technique and prognosis. Besides, it can be said all incisive canals have communication with the nasal cavity.

Background: Maxillary anterior teeth play a crucial role in aesthetics, phonetics, and mastication. For successful orthodontic treatment evaluating the morphology of the alveolar bone and incisive canal would help in avoiding root resorption, dehiscence, and fenestration. This study is aimed to research the configurational relationships among maxillary incisors, alveolar bone, and incisive canal through Cone Beam Computerated Tomography (CBCT). Methods: CBCT images of 35 orthodontic patients were evaluated for length of the canal (L); angles between the palatal plane and the maxillary alveolar border (01),the incisive canal (02), and maxillary incisor (03); distance from the right maxillary incisor to the incisive canal (D). All the measurements were performed on sagittal plane with the exception of (D) which was made on axial plane. Statistical analysis was performed on the above parameters using two sample test and Pearson’s correlation analysis. Results: There was no statistically significant difference between males and females for all the variables although there were large interindividual variation. There was a positive moderate correlation between 01 and 02 (0.480), 01 and 03 (0.487), 02 and 03 (0.345). The mean value for L and D were 10.38mm and 4.14mm respectively. Conclusion: There exists a large interindividual variability for incisive canal, proximity of incisors with that of incisive canal which could not be precisely predicted by the conventional cephalograms. The results of the study could be helpful clinically in planning orthodontic treatment for significant intrusion and retraction of maxillary incisors

The aim: To provide clinical evaluation of the effectiveness of anesthesia for cystectomy of radicular cysts that have grown into the maxillary si-nus or nasal cavity using different techniques of endonasal block-ade of the nasopalatine nerve. Materials and methods: Clinical observations were conducted on 52 patients of different age and sex. These patients were diagnosed with large radicular cysts (more than 3.0 cm in diameter) that had grown into the maxillary sinus (33 cases) or into the nasal cavity (19 cases). The surgical excisions of cysts (oroantral cystectomies) were performed un-der local potentiated anesthesia. Patients were divided into two clinical groups, depending on the methods used for endonasal blockade of the nasopalatine nerve: the main and the control group. Patients in the main group underwent endonasal blockade of the nasopalatine nerve at the point of its emergence from the pterygopalatine ganglion. In the control group, the neural blockade was performed at the entry of this nerve into the incisive canal. Pain sensitivity and perception in patients were studied using subjective and objective methods. The data was analyzed by means of the Pearson’s chi – square tests. Results: During the enucleation of radicular cysts that grew into the inferior nasal meatus and maxillary sinus in patients of the main group there was no pain observed. There were no manifestations of pain-induced stress neither from the side of autonomic system, nor physical or emotional manifestations of pain, which confirmed the effectiveness of nasopalatine nerve anesthesia. In patients of the control group during similar operation the full effect of local anesthesia was achieved in 56.0% of cases (χ2 – 9,270, р = 0,003). The rest of the patients during cystectomies showed some signs of pain-induced stress from the side of autonomic system or in the form of physical or emotional manifestations. Conclusions: Endonasal blockade of the nasopalatine nerve at the point of its emergence from the pterygopalatine ganglion invariably provided a complete analgesia during enucleation of radicular cysts that have grown into the maxillary sinus or nasal cavity. Anesthesia of the nasopalatine nerve at its entry into the incisive canal allows pain-less cystectomy of radicular cysts that have spread to the front of the inferior nasal meatus from the front teeth.
