Treatment of Class II division I malocclusion having severe crowding, proclination with noncomplaint fixed functional appliance therapy, and frictionless mechanics

Our Objective was to treat a patient having proclined, protruded teeth along with a Class II Skeletal malocclusion. 0.022 × 0.028 inch MBT Brackets were placed, and leveling alignment was commenced. Individual canine retraction was carried out in both arches, followed by retraction of the incisors in the upper arch with a Burrstone's T Loop. E2Z Forsus fatigue resistance appliance was given for the correction of Class II malocclusion. Proclination, protrusion, and crowding were corrected along with Class II Skeletal base. Individual canine retraction along with frictionless mechanics and noncompliant functional correction has sufficient potential to prevent anchor loss and correct a Class II skeletal base.

Evaluation of Preparedness for Medical Emergencies in Dental Practice among Undergraduate and Postgraduate Students

A medical emergency among dental patients can be encountered anytime. It is the responsibility of a dentist to handle the emergency in order to effectively manage it. The assessment of preparedness of medical emergencies would help to bring about required changes in the curriculum in dental institutions. Aim: The aim of this study was to evaluate and compare the knowledge of common medical emergencies among undergraduate and postgraduate students. Methods: A questionnaire based study with a sample size of 200 was conducted among 100 postgraduate and 100 undergraduate students at Kothiwal Dental College and Research Centre to evaluate their knowledge regarding medical emergencies. The questionnaire consisted of thirteen questions. Chi-square test was applied for comparing various parameters between dental postgraduates and undergraduates regarding preparedness for medical emergencies. A P-value of less than 0.05 was considered statistically significant. Results: The results of this study showed that filling health history proforma, recording vital signs, attending workshops on emergency management, performing Basic Life Support, and administering an intramuscular and intravenous injection has statistically significant results among postgraduate and undergraduate students. Conclusion: The results of this study reflect an alarming situation of the capability of dental students to deal with medical emergencies at dental offices.

Evaluation of Three Different Regression Equations Based Mixed Dentition Analysis in Children of Moradabad City, India

Objective: To assess the accuracy and applicability of three regression equations based mixed dentition analysis in children of Moradabad city, India. Material and Methods: Actual mesiodistal width of maxillary and madibular incisors, canines and premolars of 100 children (50 male and 50 female) aged 11-14 years were measured on dental cast with electronic digital vernier caliper. The analysis of Tanaka- Johnston, Ling-Wong and Jaroontham-Godfrey regression equations were tested on the dental casts. All analyses were performed on SPSS software. Data were summarized as Mean ± standard deviation (SD) paired observations were compared by paired t-test (two-tailed test) while independent groups were compared by independent Student's t-test. The level of significance was at P < 0.001. Results: The analysis of Tanaka-Johnston, Ling-Wong, Jaroontham-Godfrey regression equations tended to overestimate the mesiodistal width of the canines and premolars with the actual measured values. Conclusion: All the three regression equations based mixed dentition overestimated the mesiodistal width of canines and premolars in Moradabad population.

Co-relation of body mass index, dental caries and periodontal status with fluorosis in different high fluoridated areas of Haryana state, India.

Background and Aim: The aim of the present study is to compare the effect of corticotomy versus prostaglandin E1 injection in human subjects on rate of tooth movement, anchorage loss and their effect on crest bone height and root length. Settings and Design: Clinical interventional study. Split mouth design was used. Materials and Methods: Study was done on 32 regular orthodontic patients. A volume of 100 mcg of prostaglandin E1 was injected on the right side once in 2 weeks and on the left side corticotomy was performed, and canine retraction was started on both sides simultaneously. The rate of space closure and anchorage loss was assessed with casts. The root length and crestal bone height changes were assed with IOPAs. The comparison of rate of tooth movement, anchorage loss, crestal bone height and root length changes between the sides were statistically analyzed using paired t-test. Results: The average rate of space closure on right side was 0.36 mm/week with a standard deviation of 0.05 mm/week and on the left side average rate of space closure was 0.40 mm/week with a standard deviation of 0.04 mm/week. The difference between the rate of closure between the right side and left where found to be statistically significant (P = 0.003). The anchorage loss, the crestal bone height changes and root length changes were not statistically significant. Conclusion: The rate of tooth movement was significantly more with corticotomies when compared with given dose of prostaglandin injection.
