The opacity of lesion showed that it was composed of a dense bone and the lesion presented in the pathway of planned orthodontic tooth movement. We report a case of an asymptomatic radiopaque, non-expansive and localized lesion which occurred as an incidental finding upon routine dental panoramic radiograph assessment prior to orthodontic treatment. The radiopaque lesion which was presented in the pathway of planned orthodontic tooth movement had triggered an alarm to the orthodontist. On the basis of dental panoramic radiograph, the lesion was classified as well defined completely opaque lesion (98mmx70mm), located at the right body of mandible between tooth 44 and tooth 45 and did not attach to these teeth in adjacent to it (with continuous periodontal space separating the roots from the lesion). Nevertheless, the...

MSD can occur in any part of the body, ranging from postural muscle, upper extremities and the lower extremities. If left untreated, MSD can cause severe degenerative and inflammatory disorders. The aim of this study is to determine the prevalence of musculoskeletal disorders (MSD) among dental students. Methods: This was a descriptive cross-sectional survey involving a convenient sample of 244 undergraduate and postgraduate dental students in UKM. A previously validated self-reporting questionnaire measuring MSD prevalence, derived from the Standardized Nordic Questionnaire, was distributed to students. The questionnaire included demographic data and areas where the dental students experienced trouble (ache, pain, discomfort and numbn...

Frequent bracket failure prolongs treatment duration and causes inconvenience to patient and operator. This study aimed to compare the effectiveness of two bonding agents, i.e. the self etching primer (SEP) and the conventional etch and bond (CEB) by monitoring the incidence, time and sites of bracket failure. Eighty orthodontic patients were recruited after informed consent were obtained. A randomized split mouth technique was used where one side was bonded with CEB agent, while the other side was bonded using SEP agent. All bonded brackets were examined every 4 weeks for 20 months. Incidence of bracket failure was noted and comparison between the two groups was done using paired t-test. Time and frequent site of failure were also assessed. Out of 1314 brackets, only 33 brackets were debonded with 16 from SEP group and 17 from CEB group which statistically insignificant (p>0.05). Almost 55% of bracket failure occurred during the first 3 months after bonding for both adhesives with lower premolars was most the frequent site to fail in both adhesives (39.4%). Bracket bonded on the left side failed significantly compared to the right side. In conclusion, both self-etching primer and conventional acid-etch bonding agents are equally effective in retaining brackets clinically. Bracket failure mostly occurres during the first 3 months after bonding. The premolar brackets and the left side are mostly debonded when compared to other sites.
