Publication Cone-Beam Computed Tomographic Study of the Internal Anatomy of Lower Anterior Teeth(Kathmandu University, 2024) Nepal, M; Chakradhar, A; Pradhan, SP; Khadka, J; Tripathi, R; Bali, HABSTRACT Background A thorough knowledge of the root and canal morphology and their possible variations are essential for successful endodontic treatment. 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.

SK; Adhikari, SABSTRACT Background Although Root Canal Treatment (RCT) is considered to be a painful procedure, it actually alleviates the pain of endodontic origin. Patient may avoid root canal treatment mainly due to anxiety and fear of pain, resulting in treatment avoidance and eventual tooth loss through extraction. Objective To overview the patients’ perceptions towards Root Canal Treatments and compare those perceptions to their post treatment actual experiences. Method A prospective analytical study was conducted at the Department of Conservative Dentistry and Endodontics, Kathmandu University School of Medical Sciences (KUSMS), Dhulikhel. A structured questionnaire was administered to the patients before starting of the root canal treatment and immediately after placement of the root canal filling materials. Multiple-choice questions were used to assess patient concerns, levels of nervousness, and perceptions of anticipated versus experienced pain. Result Before initiation of treatment 38 patients (16.7%) anticipated root canal treatment to be painless, while 171 (75.3%) and 18 (7.9%) expected it to be painful and extremely painful respectively. Following treatment 123 patients (54.2%) reported no pain, whereas 98 (43.2%) and 6 (2.6%) experienced it as painful and extremely. While pain associated with the treatment was the highest pretreatment concern 60 (26.4%), the post treatment concern was time 38 (16.7%). Conclusion The study provided insights into patient’s perceptions regarding root canal treatment. Pain experienced during endodontic treatment was frequently less than anticipated pain. There was a 100% satisfaction rate with root canal treatment, and most patients expressed willingness to undergo the treatment again if needed.

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.
