Background: Understanding the association between morphological aspects in the primary dentition and its transition to the permanent dentition provides the possibility of predicting the final permanent occlusion. Study on the occlusal characteristics in deciduous dentition in Nepalese population is limited. This study was aimed to assess the occlusal characteristics and spacing in primary dentition in preschool children. Methods: The cross-sectional study was conducted among 432 preschool children around Kathmandu valley after getting permission from Institutional Review Committee of Kathmandu Medical College and Teaching Hospital. Each child fulfilling the inclusion criteria was enrolled on the study only after their assent and their parent’s consent. The primary molar relation, canine relation, overjet, overbite was assessed using Foster and Hamilton criteria with the teeth in centric occlusion. Primate and physiological spaces were assessed. Data was collected and analysis was done in SPSS version 16. Results: Among the participants, (51.9%) were male and (48.1%) female. Primate spaces was seen to be absent on157 (36.3%) children. Physiological space was seen among 190 (44%) children. Flush terminal plane molar relationship was more prevalent among 294 (68%) children. Class I canine relationship was found in 257(59.5%) children. Ideal overjet was seen in 333 (77.1%) children and ideal overbite was seen among 337(78%) children. Conclusions: Favorable characteristics traits were seen in the studied population yet longitudinal studies are recommended to predict the possible outcome in permanent dentition.
Background: Leeway space becomes important during the change of dentition and occlusal development. Objectives: The study was designed to measure the mean leeway space of maxilla and mandible of Nepalese children using Orthopantomogram radiographs and also to compare the difference between mean leeway space in male and female children. Methodology: After ethical approval, 270 OPG (Orthopantomogram) radiographs of age groups 6-12 years Nepalese children exhibiting mixed dentition were selected for the study after following the inclusion and exclusion criteria by convenience sampling method. A digital measurement in the OPG software was used to measure the mesiodistal width of deciduous canine and molars along with permanent canine and premolars in all quadrants. Results: The mean leeway space on maxilla was seen to be (0.86 ±1.97mm) while for mandible was (2.45± 1.85 mm).The leeway space in both maxilla and mandible was seen to be more in females (0.87 ± 1.87 mm) and (2.52 ± 1.85 mm) than in males (0.85 ± 2 mm) and (2.40 ± 1.90mm)respectively. Conclusion: The mean leeway space in Nepalese children was found to be less than the standard “Leeway space of Nance” which could be due to population tooth crown differences and various environmental factors. Further studies could be recommended in the future both radiographically and clinically for obtaining a standardized leeway space for Nepalese population.
According to the available literature its value ranges from 0.2 -2.5% and is more common in primary dentition. [5][6][7][8][9][10][11] This case report presents a rare case of bilateral fusion of permanent lateral incisor and canine. The purpose of this article is to highlight the rarity of the condition and to evaluate the presence of any associated pathology. Case reportA 12 year-old girl reported to the Department of Orthodontics and Pediatric Dentistry with the complaint of having large teeth within her lower jaw. Her medical history was irrelevant with her condition.Intraoral examination revealed bilateral presence of unusually large teeth in the lower right and left lateral incisor and canine region. The two sites were strongly suggestive of conjoined permanent lateral incisors and canine teeth [ Figure 1]. Deep labio-lingual groove was associated with the enlarged teeth.Radiographic evaluation of the side revealed fused 32, 33, 42 and 43 and two distinct roots and single pulp chamber and root canal were evident. [ Figure 2]. AbstractFusion is described as the union of two or more tooth buds. It is characterized by a reduced number of teeth , when fused tooth is counted as one . The prevalence of fused teeth in primary dentition is below 1% and even more less in permanent dentition. The occurrence of fusion in primary dentition may be followed by dental anomalies in permanent dentition. This case report presents a case of bilateral fusion of lateral incisor and canine in primary dentition which was followed by similar fusion in permanent dentition. The aim of this report is to highlight the rarity of such condition by virtue of the number of such cases reported in literature and to evaluate their pulpal morphologies to understand the type of fusion and presence of any other associated pathologies.
Background: Overall, children less than five years old are seen more by a physician than a dentist. Physician need more knowledge and skills to address children’s oral health due to the prevalence of dental diseases, the racial and socioeconomic disparities in disease burden, and the restricted access to dental care for many children. Thus, integrating oral health disease prevention and promotion strategies into these medical professionals’ practice becomes essential. Objectives: The objective of this study was to evaluate the knowledge and attitude of graduating medical students of Nepal towards infant oral health. Methods: A self-administered questionnaire included questions on knowledge and attitude regarding infant oral health was distributed to 180 final year MBBS students of Nepal. Data were collected and entered in Microsoft Excel sheet and analysis was done using Statistical Package for the Social Sciences (SPSS) software version 20. Results: The mean age of the participants was 23.36 ± 1.12 years. Only 23.9% of them knew that dental caries is infectious and transmissible from mother to baby and 38.9% were aware of the association of poor maternal gum health and preterm, low birth weight baby. Almost 73.9% knew that gum pads should be cleaned regularly and 46.1% knew that first dental visit of a child should be as soon as the first tooth erupts. Conclusion: This study shows that graduating medical students of Nepal were knowledgeable about some aspects of early childhood caries and infant oral health, but uncertain about other aspects like the association between poor maternal gum health and premature low birth weight babies.
