Publication Assessment of Severity and Pattern of Early Childhood Caries Using ICDAS II Criteria: A Descriptive Cross-sectional Study(Nepal Medical Association, 2024) Rai, Amita; Sundas, Sunanda; Dhakal, Neha; Khapung, AnjuAbstract Introduction: Early childhood caries is highly prevalent worldwide. The International Caries Detection and Assessment System incorporates both the non-cavitated and cavitated carious lesions with acceptable reliability. The objective of the present study was to assess the prevalence, severity and pattern of early childhood caries among children visiting outpatient department of a dental college in Nepal. The study also aimed to compare the severity and pattern based on individual tooth type. Methods: A cross-sectional study was conducted among 200 children of age group 24-71 months. The International Caries Detection and Assessment System II criteria was used to detect dental caries, and its severity and pattern. The ethical approval was taken from the institutional ethical committee (IRC Reference number: 1, 36, 2079/2080 IRC PDCH 2022 21). Results: Highest caries prevalence was seen among 48 to 60 month olds, whereas lowest prevalence was seen among the 24 to 35 month-old children. Based on severity, dentinal caries (Code 5) 526 (13.19%) was the most prevalent and undermined dentinal caries (Code 4) 36 (0.9%) was the least prevalent. The most common pattern of dental caries was multi-surface caries 644 (16.15%), and the least common pattern was the lingual surface caries 22 (0.55%). Prevalence of dental caries was highest in occlusal surface of mandibular second molars 151 (37.75%), and 227 (5.69%) of the teeth had received restoration and sealants of some sort (CARS). Conclusions: Majority of the children enrolled in the study had multiple cavitated and non-cavitated carious teeth involving different surfaces. Severity and pattern of caries also varied among individual tooth type.Publication C-Shaped Canal in Second Molar of Mandible among Cases of Cone Beam Computed Tomography in Tertiary Care Centres: A Descriptive Cross-sectional Study Authors(Nepal Medical Association, 2021) Joshi, Neera; Shrestha, Suraj; Sundas, Sunanda; Prajapati, Kranti; Wagle, Sharada Devi; Gharti, ArchanaAbstract: Introduction: C-shaped canal configuration is mostly found in the mandibular second molar. The morphological characteristic of a C-shaped canal is the presence of a fin or web connecting the individual canal, making it difficult for cleaning, shaping, and obturation. The objective of this study was to find out the prevalence of C-shaped canal in mandibular second molar among cases of Cone Beam Computed Tomography in tertiary care centres. Methods: The descriptive cross-sectional study was conducted in the department of conservative dentistry and endodontics of tertiary care centres from 20th June 2020 to 20th December 2020 after receiving ethical approval from the Nepal Health Research Council on 19 June 2020. Cone-beam computed tomography images of 199 mandibular second molars with completely formed roots were used. Teeth with orthodontic braces, root resorption, root canal filling, and post were excluded from the study. The research was conducted taking a tooth as a unit. Convenience sampling was done. Statistical analysis was done by using Statistical Package for Social Sciences version 16. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Results: The prevalence of C-shaped canal according to this study is 25 (12.6%) (7.99-17.21 at 95% Confidence Interval). Conclusions: The findings of the study conclude that C-shaped configuration is quite frequent in mandibular second molar among cases of Cone Beam Computed Tomography. A careful pre-operative radiographic evaluation may be helpful for diagnosing C-shaped configuration prior to root canal treatment.
