The newly developed regression equations are more accurate for prediction of width of unerupted permanent teeth in a Nepalese population. Further studies are required based on larger sample size, to confirm the applicability of the new regression equations proposed.
Background: Pharmacotherapy plays important role in the management of paediatric dental patients in the department of paediatric dentistry. Many children at their early age suffer from different kinds of dental conditions such as acute and chronic irreversible pulpitis, acute and chronic alveolar abscesses, dentoalveolar and vestibular abscesses, etc along with physiological tooth movement that requires professional help for dental treatment. Treatment of such conditions most frequently requires pharmacotherapy as an either adjunct to dental therapeutic procedure or as a monotherapy. Objective: To assess the prescribing patterns vis-a-vis generic or trade name, generic class, dosage form, route, frequency, duration, number of drugs per patient, cost and indication of drug therapy, patterns of dental treatment and Frankl's behavioral rating. Materials and methods: Prescriptions of 200 paediatric dental patients undergoing dental treatment in the department of paediatric dentistry were analyzed prospectively for a period of six months in a dental teaching hospital. Results: 133 (56.5%) patients were males and 87 (43.5%) females and age group 6-10 years was the most frequent group (70%, P=0.0000000) and all the patients received pharmacotherapy. Total numbers of 357 drugs were prescribed. Out of them, 212 (59.4%, P=0.0000008) were analgesic agents, 133 (37.3%) antimicrobial agents (AMAs) and 12 (3.3%) other drugs. Extended spectrum Penicllins were the most commonly prescribed (90.2%) AMA followed by Metronidazole (9.8%). 247 drugs (69.2%, P=0.0000000) were prescribed by trade names. 60% (P=0.0000002) drugs were prescribed in the form of tablet or capsule followed by syrup 37% and administered entirely through oral route. Percentage of patients receiving three drugs, two drugs and one drug was 13.5%, 56.5% (P=0.0000000) and 30% respectively and one patient received on average 1.78 medicines. 133 patients (56.5%, P=0.0000000) received both AMA and analgesic agent. Minimum to maximum number of days for pharmacotherapy were 2 to 15 and highest frequency was up to four times a day. Cost of medicines was in the range of 10-150 Nepalese Rupees. Chronic irreversible pulpitis was the commonest diagnosis (28%) and extraction (92.5%) was the commonest dental procedure. Frankl's behaviour rating showed that 78.5% (P=0.0000000) patients had positive attitude towards the dental procedures. Conclusion: Findings of the study suggest that pharmacotherapy is the mainstay in therapy to treat the paediatric dental patients along with dental procedures either to control the dental pain or odontogenic infection. Age group 6-10 years, chronic irreversible pulpitis and dental extraction are the commonest age group, diagnosis and dental procedure respectively in the department of paediatric dentistry. Analgesic (non-steroidal anti-infl ammatory drugs-Nimesulide, Ibuprofen and Paracetamol) and Amoxicillin are the most frequently prescribed drugs mostly in the solid dosage forms in trade names via oral route. Duration of pharmacother...
Background: The purpose of this study was to gather normative data on the mesio-distal crown dimensions amongst adolescent population of Province II, Nepal, to make an accurate diagnosis and treatment planning in orthodontics. It will also be useful in various clinical disciplines of dentistry including basic dental and anthropological research. Materials and Methods: Samples were selected Full form OPD of M B Kedia Dental College, Birgunj, Nepal. Total numbers of participants were 120, out of which 60 males and 60 females were selected after initial examination aged between 11 to 23 years. Subjects with all permanent teeth erupted (except second and third molar) without any history of previous orthodontic treatment and with no dental anomalies were included in this study. The alginate impressions were made by the well trained dental surgeon. Digital vernier calliper providing measurements to ± 0.01millimeter(mm) was used to measure the mesio-distal dimension of all teeth. Results: The mean, range and standard deviation were calculated for the size of the teeth. Independent t-test was used to compare between male and female population. The significance level was set at p value <= 0.05. The population of Province II, Nepal shows greater sexual dimorphism in mesio-distal crown dimension which was exhibited by the maxillary molars (0.88 mm) followed by mandibular molars (0.38 mm). Similarly in anterior tooth segment the maxillary canines (0.29 mm) followed by the mandibular canines (0.27 mm). Conclusion: The mean mesio-distal crown dimensions of the permanent dentition of males were larger than that of females for each type of tooth except maxillary central and lateral incisor.
The article presents a case report of a teen age girl with Class II Division 2 malocclusion with deep over bite. The case was treated on non-extraction basis using 0.018 pre-adjusted edgewise appliance with anterior bite plate (monobloc) to correct deep bite and forward placement of the mandible. Use of Class II elastics helped to achieve Class I canine and molar retention. Treatment was completed in 22 months with good occlusion and facial esthetics.

Introduction: Malocclusion is one of the commonest problem in dentistry and the knowledge on its prevalence on particular population group is very important to plan oral health activities. The objective of this study is to assess the prevalence of malocclusion in school going children of Parsa district, Nepal, and to compare the same with previous study. Materials and Method: The sample consisted of 250 males and 210 females (total of 460 subjects) aged between 6 to 17 years. Subjects without any previous orthodontic treatment and with no dental anomalies were included in this study. Census sampling was done for the patient visiting orthodontic from November 2018 to March 2019. Classification of malocclusion was based on Angle’s classification of malocclusion. Collected data were entered in Microsoft Excel 2007 and converted into Statistical Package for Social Science (SPSS) Version 11.5 for statistical analysis. For descriptive statistics, percentage and proportion, were calculated, also tabular presentation were performed. For inferential statistics, Chi square test were used for intergroup comparison. Result: School going children of Parsa district, Nepal suggests 50.47% female and 45.6% of male exhibits Angle’s Class I malocclusion, 29.04% female and 30% male exhibits class II pattern, 11.4% female and 12.0% male exhibits class III pattern. The other findings reported in the study were, the occurrence of crowding of teeth more in males whereas the occurrence of spacing is more in females. Conclusion: Majority of the subjects in the study had Class I malocclusion. Only 9.04% female and 12.4% of male showed normal class I occlusion. The occurrence of crowding of teeth more in males whereas the occurrence of spacing is more in females. This may be due to the incidence of missing tooth is more in females.
Introduction: The position and movement of incisors play important role in orthodontics. Efficient tooth movement and stable position cannot be ensured without adequate alveolar bone support. The bone loss estimated by traditional radiograph is always less than real bone loss so CBCT is currently best to evaluate bone changes. The purpose of this study was to use CBCT to evaluate and compare changes in alveolar bone thickness and Vertical alveolar bone height around maxillary anterior teeth of Class I malocclusion patient after orthodontic treatment. Materials and Method: Forty patients with Class I occlusion between ages of 12 to 18 years were selected. The cone beam computed tomography (CBCT) and lateral cephalograms were taken before treatment (T0) and after treatment (T1). The lateral cephalograms were used to assess the change in tooth inclination whereas CBCT was used to assess the alveolar bone change. All the data were statistically analyzed using paired sample t-test and independent sample test. Result: Significant changes in alveolar bone thickness and vertical bone height were found on the palatal surface of the anterior teeth compared to that of labial surface with significant change in tooth inclination. Conclusion: Based on the results, we can conclude that the palatal alveolar bone loss and vertical bone loss was greater than that of the labial alveolar bone.
Introduction: The tooth size ratios may vary among different ethnic groups and different malocclusion groups. The objective of this study is to see the tooth size discrepancies in two major ethnic groups of Nepal; Indo-Aryans and Tibeto-Burmans and different malocclusion groups and compare it with the Bolton’s study. Materials and Method: The anterior and overall ratios were compared between Indo-Aryans and Tibeto-Burmans according to different malocclusion groups with Bolton’s study with one sample t-test. The differences in ratios in ethnic groups and gender were seen with one sample t-test. The differences in mesio-distal tooth width amongst the two ethnic groups were seen. One sample ANOVA was used to see any correlation between the ethnic groups and the different malocclusion groups. Result: The anterior ratio and overall ratio in Indo- Aryans and Tibeto-Burmans in all the malocclusion groups were greater than the Bolton’s study but was not statistically significant. There was significant differences in anterior ratio between Indo-Aryans (77.63 + 2.74%) and Tibeto-Burmans (78.51 + 2.76%), p value= 0.024. There were no statistical significant differences in the anterior and overall ratio amongst males and females. The mesio-distal tooth size was greater in Tibeto-Burmans as compared to Indo-Aryans expect for maxillary right and left central incisors. Conclusion: The Tibeto-Burmans had higher anterior ratio as compared to Indo-Aryans. The Tibeto-Burmans had broader teeth as compared to Indo-Aryans except for maxillary central incisors.
