Classifying the partial edentulous arches is necessary as it helps in treatment planning, designing and recognition of prosthetic support for removable partial denture. The main aim of this study was to access patterns of partial edentulism among patients and determine its association with socio-demographic parameters.</p> <p><strong>Methods:</strong> Patients from various municipalities of Kavre district were selected for the study. Total of 206 patients were selected. The study was divided into two part. Questionnaire related to demographic data and intraoral examination to evaluate the pattern of partial edentulism according to Kennedy's Classification and Applegate's rule. The chi-square test was used to determine the association between Socio-demographic variables and pattern of partial edentulism. Statistical evaluation will be done using the Statistical Package for Social Sciences (SPSS 20.0), the level of significance set at p-value &lt;0.05.</p> <p><strong>Result:</strong> The number of partially edentulous was less in the age group 20-30 years 38 (27.33%) and 45(28.48%) respectively, whereas, it was high in age group above 50 years 52 (37.41 %) and 57 (36.08 %) respectively. Kennedy's Class III was the most common type of partial edentulism in both maxillary arch 62 (48.82%) and mandibular arch 71 (46.71%) followed by Class I in both maxilla 31(24.41%) and 38(25%). The least common type of partial edentulism was found to be Class IV. Among the modifications Class III Modification I was the most prevalent condition in both maxillary 17 (27.42%) and mandibular arch 22 (30.9%).</p> <p><strong>Conclusion:</strong> The study showed that age had statistically significant association with different classes of partial edentulism in both maxillary and mandibular arches. Whereas, gender had no association with the patterns of partial edentulism.</p> 2023-09-05T00:00:00+00:00 Copyright (c) 2023 S KC Basnyat, D Prajapati, S Mahanta https://www.nepjol.info/index.php/jnprossoc/article/view/58348 Correlation of Inter-Canine Width of Maxillary Anterior Teeth with Interpupillary Distance and Inner Inter-Canthal Distance 2023-09-05T05:37:30+00:00 S Dhital shaishabdhital@gmail.com B Ghimire shaishabdhital@gmail.com <p><strong>Introduction:</strong> The selection of proper sized maxillary anterior teeth poses a challenge and numerous efforts have been made to develop methods for estimating the inter-canine width of maxillary anterior teeth. In this clinical study, the objective was to investigate the correlation between interpupillary distance (IPD), inner inter-canthal distance (ICAD) and inter-canine width of maxillary anterior teeth (ICW).</p> <p><strong>Methods:</strong> The subjects were comfortably seated on a dental chair in a relaxed state in an upright position with the head resting firmly against the headrest. The parameters were measured using a digital caliper. To determine IPD, the midpoint of the pupils was marked and measured. Likewise, the width of ICAD was assessed by measuring between the medial angle of the palpebral fissure of the eyes. The inter-canine width of maxillary anteriors form the distal surface of left and right canines were measured with a dental floss, which was then sectioned and measured. Each parameter was measured thrice, and the average value was calculated and recorded.</p> <p><strong>Results:</strong> Mean IPD, ICAD and ICW were 60.8 mm, 31.5 mm and 49.7 mm respectively. Statistical analysis revealed a highly significant difference between IPD and ICW teeth of male and female respectively. Spearman's rho analysis showed statistically significant correlation between ICW and IPD (r=0.156, p =0.006). Similarly, Spearman's rho analysis in male group also showed statistically significant correlation between ICW and IPD (r= 0.374, p=0.00025).</p> <p><strong>Conclusion:</strong> This study concluded that there was significant correlation between interpupillary distance and ICW. The measurement of IPD can serve as a valuable reference for guiding the selection and placement of artificial maxillary anterior teeth.</p> 2023-09-05T00:00:00+00:00 Copyright (c) 2023 S Dhital, B Ghimire https://www.nepjol.info/index.php/jnprossoc/article/view/58349 Flexural Strength of Heat Cure Denture Base Resin incorporated with Curcumin: An In-Vitro Study 2023-09-05T05:43:36+00:00 LR Khanal amarbhochhibhoya@gmail.com A Shrestha amarbhochhibhoya@gmail.com KR Joshi amarbhochhibhoya@gmail.com A Bhochhibhoya amarbhochhibhoya@gmail.com <p><strong>Introduction:</strong> Acrylic resin when used for fabrication of denture is susceptible for microbial colonization. Many antimicrobial agents have proven effective against the microbial colonization when they were incorporated into the acrylic resin but adding anything into the acrylic resin can alter its mechanical properties resulting into unacceptable intraoral use. This study was done to evaluate if<br />adding an antimicrobial agent, Curcumin, alters the flexural strength of acrylic agent.</p> <p><strong>Methods:</strong> 172 acrylic strips were fabricated. They were divided equally into 4 groups depending upon concentration of curcumin as Control, T1: 1% curcumin, T2: 3% curcumin and T4: 5% curcumin. Flexural strength was tested using 3-point bend test using Universal Testing Machine.</p> <p><strong>Results:</strong> There was no significant difference in values of mean flexural strength for control, 1% and 3% curcumin groups. There was significant difference in the mean value between control and 5% curcumin group.</p> <p><strong>Conclusion:</strong> 1% and 3% curcumin can be incorporated into acrylic resin without significantly altering its mechanical properties.</p> 2023-09-05T00:00:00+00:00 Copyright (c) 2023 LR Khanal, A Shrestha, KR Joshi, A Bhochhibhoya https://www.nepjol.info/index.php/jnprossoc/article/view/58350 Cephalometric Assessment of Condylar Position among Individuals with Different Skeletal Malocclusion Patterns 2023-09-05T05:51:04+00:00 P Poudel sirjanadahal11@gmail.com S Dahal sirjanadahal11@gmail.com <p><strong>Introduction:</strong> There are variations in growth and orientation of cranial base region where the maxilla and mandible articulate. This leads to differential movement of the maxilla and mandible causing changes in glenoid fossa and condylar position. Therefore, this study was conducted to determine the condylar position in patients with different skeletal sagittal malocclusion patterns.</p> <p><strong>Methods:</strong> An analytical cross-sectional study was conducted among 165 individuals, having skeletal Class I, Class II and Class III relationship (55 in each group) selected by convenience sampling method after receiving ethical approval and informed consent. Lateral cephalograms were taken and measurements for determining condylar position were done and compared among three groups. Data were analyzed in SPSS version 16. Kruskal-Wallis H test was used to determine the mean difference in between condylar positions of three skeletal malocclusion patterns and Mann-Whitney U test was done for their pairwise comparison.</p> <p><strong>Results:</strong> There was no significant difference in posterior cranial base length (P=0.200) and saddle angle (P=0.517) in three skeletal malocclusion class groups. However, the three malocclusion patterns showed significant differences in gonian angle (P=0.001) and articular angle (P=0.013). Significant moderate negative correlation in saddle angle and articular angle (P&lt;0.001) was observed.</p> <p><strong>Conclusion:</strong> The findings of this study concluded that condylar position based on posterior cranial base length was not associated with different skeletal malocclusion patterns. However, articular angle was significantly lower in skeletal class III than in class II.</p> 2023-09-05T00:00:00+00:00 Copyright (c) 2023 P Poudel, S Dahal https://www.nepjol.info/index.php/jnprossoc/article/view/58351 Increased Occlusal Vertical Dimension and Its Influence on Lip Position at Smile in Dentulous Adults 2023-09-05T06:02:23+00:00 N Dhyako niraaz98@gmail.com S RB Mathema niraaz98@gmail.com K Shrestha amarbhochhibhoya@gmail.com SK Maharjan amarbhochhibhoya@gmail.com B Maskey amarbhochhibhoya@gmail.com R Gautam amarbhochhibhoya@gmail.com <p><strong>Introduction:</strong> Increasing occlusal vertical dimension (OVD) is often indicated in complex prosthodontic rehabilitations to gain restorative space and improve the occlusal relationship and esthetics. However, any alterations made in OVD will also influence the lip position mainly during rest and smile. This study aims to determine the influence of the vertical dimension of occlusion on lip positions at a smile.</p> <p><strong>Methods:</strong> 30 samples between the age group of 20 - 30 years were included in this study meeting the selection criteria. The acrylic splint of varying thicknesses of +2mm, +4mm, +6mm, +8mm was prepared on the dental stone cast of a patient that was articulated in a semi-adjustable articulator after tentative facebow transfer. Smile photograph of each individual at the occlusal vertical dimension of +0mm, +2mm, +4mm, +6mm, +8mm was taken using a DSLR camera mounted on a tripod using the prepared acrylic splints. Digital measurements were done in photographs using the Adobe Photoshop software.</p> <p><strong>Results:</strong> The study's results demonstrate that increasing the OVD significantly affects the inter labial distance, incisal edge to lower lip distance, and the display zone area. However, the study found no notable alterations in the distance from the incisal edge to the upper lip or in the intercommissural width with the same increased OVD. These findings demonstrate on how changes in OVD can influence various orofacial measurements.</p> <p><strong>Conclusion:</strong> Within the limitation of this study, it can be concluded that with the increase in the OVD, inter labial distance, incisal edge to lower lip distance, and display zone area are increased. But upper lip position and inter commissural width should not be expected to be changed with increased OVD.</p> 2023-09-05T00:00:00+00:00 Copyright (c) 2023 N Dhyako, S RB Mathema, K Shrestha, SK Maharjan, B Maskey, R Gautam https://www.nepjol.info/index.php/jnprossoc/article/view/58352 Management of cleft palate in middle schooler: A case report 2023-09-05T06:11:09+00:00 KR Joshi manjeevguragain@gmail.com G Das amarbhochhibhoya@gmail.com A Shrestha amarbhochhibhoya@gmail.com LR Khanal amarbhochhibhoya@gmail.com M Guragain amarbhochhibhoya@gmail.com <p>A cleft lip and/or palate is a congenitally persistent fissure in the upper lip, alveolus, hard palate, or soft palate that can contribute to hearing loss, speech impediment, feeding issues, dental malocclusion, and nasal deformity. The oronasal communication reduces the capacity to produce the essential negative pressure for sucking and causes nasal regurgitation of food and may even lead to choking. The feeding plate seals the fissure and restores the wall separating the nasal cavity from the oral cavity.</p> 2023-09-05T00:00:00+00:00 Copyright (c) 2023 KR Joshi, G Das, A Shrestha, LR Khanal, M Guragain https://www.nepjol.info/index.php/jnprossoc/article/view/58353 Prosthetic rehabilitation in the Posterior Mandible with Tissue Level Implant: A Case Report 2023-09-05T06:26:49+00:00 K Lamichhane lmchkp@gmail.com S Pradhan lmchkp@gmail.com R Gorkhali lmchkp@gmail.com B Shrestha lmchkp@gmail.com <p>Implant is becoming the most appropriate option nowadays for replacement of single or multiple missing teeth which offers the predictable long-term results. Continuous innovations in implant design and approaches for placement have been proposed to achieve good osseointegration, esthetics and predictable soft tissue contour. Soft tissue level (STL) implants are placed trans-mucosally with platform away from alveolar bone crest so the microbial deposits in the micro-gap at implant abutment connection has less effect on alveolar bone. This type of implant has a rough surface placed subcrestally to facilitate osseointegration and a polished coronal part to facilitate soft tissue adaptation. This case report highlights about soft tissue level implant, its advantages and clinical success on replacing single missing posterior tooth.</p> 2023-09-05T00:00:00+00:00 Copyright (c) 2023 K Lamichhane, S Pradhan, R Gorkhali, B Shrestha
