Publication Assessment of Range of Motion of Temporomandibular Joint among Dental Students of Dhulikhel Hospital(Kathmandu University, 2024) Luitel, A; Bali, H; Gautam, P; Shrestha, R; Singh, N; Gurung, KABSTRACT Background Restriction in mandibular range of motion (ROM) is one of the main signs of mandibular dysfunction and an important criterion for evaluation of functional state of the masticatory system. Objective The objective of this study was to evaluate the normal ROM of Temporomandibular Joint (TMJ) among dental students of tertiary care hospital at central region of Nepal. Method After ethical clearance, cross- sectional study was conducted between August to September 2022 among all dental students who gave consent. The inter-incisal opening, bilateral lateral excursion and protrusion were measured thrice using 15 cm metallic scale and an average was considered to reduce ambiguity. The data was entered in Microsoft excel and transferred to SPSS version 20 for statistical analysis. The descriptive statistics was calculated and independent t test was applied to compare the mean between genders. Result Total of 145 students (25 males and 120 females) were included with the mean age of 21.32 ± 1.29 years. The overall mean inter-incisal opening was 44.82 ± 5.80 mm, right lateral excursion was 8.23 ± 2.11 mm, left lateral excursion was 8.70 ± 1.80 mm and protrusion was 5.65 ± 1.87 mm. There was statistically significant difference in right and left lateral excursion and protrusion among genders. Conclusion The inter-incisal opening of participants in our study appeared towards lower range of normal mouth opening while lateral excursion appeared consistent with those described in the literature. The protrusive movement of our participants was decreased, compared to those recorded in the literature.

Methods like staining and clearing techniques, cross sectional method can provide precise information on root canal systems, however, these methods are invasive. Cone-beam computed tomography (CBCT) is the 3-dimensional scans of the maxillofacial skeleton that best visualizes canal morphology and helps in identifying additional canals and roots in vivo. Objective To investigate the root canal configuration of mandibular anterior teeth using Cone- beam computed tomography. Method A total of 2910 CBCT images, comprising 970 central incisors, lateral incisors, and canines each from 485 patients were assessed. The following assessments were made: (1) The number of roots and root canals (2) Canal configuration according to Vertucci’s classification (3) Bilateral occurrences for variations. Also, the gender and age of patients were noted. Result The study revealed mandibular anterior teeth predominantly had 1 root with Type I (79.79%, 77.11%, 91.34%) canal configuration followed by type III (20.2%, 22.67%, 5.15%) in central, lateral and canine respectively. Almost 90% incisors had symmetry in the canal configurations. No statistical correlation was found between the gender and root canal configurations. Type III canal configurations in canines were present more in elder age group. Conclusion Clinicians must be aware that each tooth may display a different number of roots and types of canal configurations. During endodontic treatment, presuming lower anterior teeth with single root and single canal may lead to missed canals and consequently, treatment failure.

The knowledge of root canal morphology and its variation is crucial for the endodontic success. Objective To evaluate the root and canal morphology of mandibular premolars in a Nepalese population by using Cone Beam Computed Tomography. Method A total of 1924 mandibular first and second premolar teeth from 481 patients were evaluated. The number of roots and canal configuration were identified and categorized according to Vertucci’s classification. An association between number of roots and root canal configuration with gender and ethnic group was evaluated. Also, the bilateral symmetrical occurrence of root and canal configuration were investigated. Result Majority of mandibular first premolars (86.7%) and second premolars (98.7%) were single rooted with type I root canal configuration followed by type V (8.6%) in first premolars and type III (0.6%) in second premolars while 3.8% of first premolars and 0.6% of second premolars were two rooted. In first premolars, there was an association between gender with number of roots (p-value = 0.007) and root canal configuration (p-value < 0.001). High degree of bilateral symmetry was seen in both first (85.4%) and second premolars (96.9%) in terms of the number of roots and canal configuration. Conclusion Most of the mandibular premolars were single rooted with Type I canal configuration. However, clinicians should be aware of the variations that may be encountered during routine endodontics which may influence the success behind treatment.
