Dental Undergraduate Students View Towards Orthodontic Treatment Based on a Questionnaire Study

Perception and Knowledge of orthodontic treatment are pre-requisite for orthodontic treatment-related behavior. Adolescence is the time when a person attains knowledge including the self-awareness about his or her oral health. Hence if proper knowledge is instilled during this time, it will be effective. The aim of this study was to compare the knowledge and perception of dental undergraduates toward orthodontic treatment. This is a descriptive cross-sectional single-center questionnaire study, carried among 449 dental students of dental college among 1st years, 2nd years, 3rd years, final years, and interns at Chengalpet district aged between 18 and 27 years, respectively. The questionnaires consisted of seven knowledge-based and five perception-based questions related to orthodontic treatment. Each question had three answers “yes” “no” and “don’t know.” The data were collected through google forms and total responses were calculated. The mean percentage was calculated and compared between 5 years. The results showed that percentage of knowledge and perception for 1st years, 2nd years, 3rd years, final years and interns increases as they progress from 1st year through internship. Overall the study showed that dental students had good knowledge and perception towards orthodontic treatment but varies among years. First years and 2nd years had lesser knowledge compared to 3rd years. Third year had lesser knowledge compared to final years and interns. Interns and final years have more knowledge compared to 1st years, 2nd years, and 3rd years. Subjects who were in lower age group comprising of 1st, 2nd, and 3rd years showed less knowledge and perception compared to higher age group subjects present in final years and interns towards orthodontic treatment

CBCT in orthodontics: A boon for the millennial generation

Most orthodontic patients, unlike those having implants or endodontic treatment, are children who are particularly vulnerable to ionising radiation. In orthodontics, cone-beam computed tomography (CBCT) has both hazards and benefits. Ionizing radiation, the existence of artefacts, higher costs, limited accessibility, and the need for additional training are the main hazards and limits. This imaging modality, however, has several recognised indications in orthodontics, including the assessment of impacted and ectopic teeth, the assessment of pharyngeal airway, the assessment of mini-implant sites, the evaluation of craniofacial abnormalities, the evaluation of sinus anatomy or pathology, the evaluation of root resorption, the evaluation of the cortical bone plate, and the planning and evaluation of orthognathic surgery. For certain patients, CBCT should be considered for clinical orthodontics. The use of CBCT requires careful consideration and strong clinical judgement. The important themes and topics in the literature about application of CBCT in orthodontics are summarised in this review

Ballista Spring - A Conservative Method for Repositioning Palatally Impacted Canine - Clinical Case Report

Maxillary canine impaction is one of the most frequently encountered condition in orthodontic practice. Many factors are responsible for the development of canine impaction. Early diagnosis and interception can provide prudent clinical management of impacted canine with minimal or no iatrogenic effects. The Ballista spring system is a simple, less traumatic system for treating impacted canines. The impacted teeth is retracted by a spring that accumulates light continuous force from being twisted on its long axis. This article illustrates a case in which impacted maxillary canine was surgically exposed, attachment bonded, vertical and labial traction given with Ballista spring and ideally positioned with fixed orthodontic mechanotherapy

SYNTHESIS AND CHARACTERIZATION OF NEW CHALCONES OF 4-FLUORO-3-METHYL ACETOPHENONE

In the present investigation it has been considered worthwhile to synthesize some new chalcones from 4-fluoro-3- methyl-acetophenone and different aromatic aldehydes by Claisen-Schimdt condensation. The synthesized compounds were characterized by means of Chemical analysis, IR and 1H NMR spectroscopic data. Key words: Flavonoids, Chalcone, IR and 1H NMR spectroscopy

A Taxonomy of Sensor Network Architectures

Several architectures have been proposed for sensor networks. However, there is a lack of an over-arching sensor network architecture. Here we present some of the issues associated with existing sensor network architectures. Next we present several sensor network architectures, including one suitable for a multi-owner environment, classifying these architectures in terms of function and compositional elements. We also highlight each architecture’s key attributes in order to identify their commonalities. In making our arguments we refer to the concept of invariants, which are components of a system that cannot be changed without losing backward compatibility [1]. Our results show that while several sensor network architectures exist, each with different attributes, these architectures share several invariants. Key words
