The use of digital and imaging technology for students’ evaluation in simulation operative technique

Objectives: To evaluate the efficacy of using digital and imaging technology in the assessment of students in the simulation operative technique. Methods: 47 students in the kulliyyah of dentistry/International Islamic University Malaysia was examined for Class II cavity preparation for amalgam on plastic tooth number 46. The evaluation was done by two faculty members using the digital and imaging technology acronym as "DIET" (Dental Instruction, Evaluation and Training System). Results were compared with marks obtained by direct visual assessments. Fifteen percent of the preparations were reevaluated to determine intra-examiner reliability. The evaluations also were analyzed for inter-examiner reliability. Results: The results taken through the use of the digital and imaging system was found to have no significant difference with those obtained from the direct visual assessment. Conclusion: The use of the new digital and imaging technology is helpful to facilitate web-based teaching and assist Dental faculties’ members in the grading of dental students. This would allow Malaysian dental faculties to be in the league of globally-known dental faculties which are using similar solutions. The use of the system has several advantages over the traditional method. It frees the lecturers from the paperwork and reduces the direct contact with students allowing lecturers to evaluate all aspects of the procedure at any time. This also decrease or eliminate students’ need to wait “in line” for evaluation. Limitation of contact with patients may reduce the cross-infection

The golden proportion among Malay students in IIUM/ Malaysia

The maxillary anterior teeth are significant in achieving beautiful dental aesthetics. This study aimed to find the application of golden proportion on Malaysian populations. Materials and methods: The sample size consisted of 100 students from any faculty, 50 men and 50 women, ranging in age from 20 to 25 years old. The subjects have all of their natural anterior teeth, no history of orthodontic treatment or tooth size alteration and are of Malay origin. Impression was taken and measurements done by using cast. The golden percentage calculated by dividing the width of each central incisor, lateral incisor and canine by the total width of all six maxillary anterior teeth, multiplied by 100 in order to obtain the golden percentage for each tooth. The golden proportion found to be accurate between the width of the right central and lateral incisors in 33.2% of men and 33.1% of women subjects. 13.9% of male and 13.6% of female subjects have the widths of their right lateral incisors in golden proportion to the widths of their right canines. Moreover, the data shows 37.2% of the male and 37.1% of the female subjects have the widths of their left central incisors in golden proportion to the widths of the eft lateral incisors Golden proportion is applicable to Malay population. The width of the central incisor represents 24%, lateral incisor 16% and canine 10% of the width of the six maxillary anterior teeth as viewed from the front

Evaluation of maxillary anterior teeth and their relation to the golden proportion in Malaysian population

The maxillary anterior teeth are important in achieving pleasing dental aesthetics. Various methods are used to measure the size and form of them, including the golden proportion between their perceived widths, and the width-to-height ratio, referred to as the golden standard. The purpose of this study was conducted to evaluate whether consistent relationships exist between tooth width and height of the clinical crown dimensions; and to investigate the occurrence of the golden proportion of the maxillary anterior teeth. Dental casts of the maxillary arches were made in this cross-sectional study from MAHSA University College students who met the inclusion criteria. The 49 participants represented the Malaysian population main ethnics. The dimensions of the anterior teeth and the perceived width of anterior teeth viewed from front were measured using a digital caliper. Comparison of the perceived width ratio of lateral to central incisor and canine to lateral incisor with the golden proportion of 0.618 revealed there were a significant statistical difference (p < 0.05). The statistical difference was significant for the width-to-height ratio of central incisors to the golden standard of 80%. There was no significant difference in the comparison among ethnic groups for the golden proportion and the golden standard. The golden proportion was not found to exist between the perceived widths of maxillary anterior teeth. No golden standard were detected for the width-to-height proportions of maxillary incisors. Specific population characteristics and perception of beauty must be considered. However, ethnicity has no association with the proportions of maxillary anterior teeth
