Supernumerary teeth are extra teeth in comparison to the normal dentition. Their prevalence varies between 0.1% and 3.8%. Supernumeraries are more common in permanent dentition and its incidence is higher in maxillary incisor region, followed by maxillary third molar and mandibular molar, premolar, canine, and lateral incisor. The prevalence of supernumerary premolars is between 0.075-0.26%, and they may occur in single or multiple numbers Bilateral occurrence is uncommon and large percentage of supernumerary premolars remains impacted, unerupted, and usually asymptomatic; radiograph plays an important role in diagnosis of these. The present paper reports a case of bilaterally impacted completely developed supernumerary premolars associated with common clinical complication in unusual manner along with taurodontism of the upper and lower molars.
Valid and reliable assessment of students' knowledge and skills is integral to dental education. However, most faculty members receive no formal training on student assessment techniques. The aim of this study was to quantify the value of a professional development program designed to improve the test item-writing skills of dental faculty members. A quasi-experimental (pretest, intervention, posttest) study was conducted with faculty members in the dental school of Majmaah University, Saudi decreased, those with high discrimination increased, and the proportion of questions with more than two non-functional distractors were reduced. These results provide evidence of improved test item quality following implementation of a long-term faculty its value for dental schools.Saleem Shaikh is Lecturer,
Aim:The aim of this study was to evaluate the accuracy in the perception of the own facial profi le by subjects and to compare the orthodontist's perception of attractive profi le with those of laypeople and dental students. Materials and Methods: In this study, 180 subjects (90 dental students and 90 laypeople) from Riyadh province of Saudi Arabia were evaluated by a questionnaire. The questionnaire was designed to fi nd out the most attractive profi le among the two groups, the perception of own facial profi le and expectations of subjects from orthodontic treatment. The facial profi les of the individuals were evaluated by two clinicians separately. The diff erences among groups in the perception of the own profi le were compared by using Chi-square (χ 2 ) test. Kappa coeffi cient was used to assess the agreement between the two groups. For all statistical analysis P < 0.05 was set as the signifi cance level.
Results:The most attractive profi le perceived by both the groups was Class I, followed by straight profi le and least attractive was Class III profi le with the protrusive mandible. The diff erence in the profi le perception between the clinicians and subjects was statistically signifi cant (P < 0.05).
Conclusion:The most attractive profi le perceived by both the groups was Class I, followed by straight profi le dental students were more accurate in the perception of the own profi le. The expected profi le of patients after orthodontic treatment is not same for all the subjects.
