A case of a large dentigerous cyst associated with canine tooth in the maxillary antrum is presented. This case is of interest because of its extensiveness and the presence of an ectopic tooth in the roof of the maxillary sinus. Theoretical aspects of canine impaction and cyst formation are reviewed. The management of a jaw cyst, in particular, the still popular Caldwell-Luc procedure is discussed.

Osteoporosis-related fractures have been recognized as a major health problem, particularly in the elderly with a high morbidity and mortality rate. The aims of the study were to identify knowledge and perception toward calcium intake among students at UiTM and to explore the differences between genders in dietary calcium intake. A cross sectional study was conducted through 336 students aged 18 to 34 years old. The participants were randomly chosen from the student’s enrolment list. A modified questionnaire was used to obtain the knowledge and perception of the participants. More than half of the participants have low knowledge regarding dietary calcium intake (58.6%), positive view towards the benefits of calcium intake and low perception towards the barrier of calcium intake. Chi square analysis showed a significant difference between male and female for knowledge (p=0.034) and barrier (p=0.002) for calcium intake. Intervention programs should be adopted to increase the knowledge among young adults to improve their health and prevent risk factors. So, health education specifically on calcium intake will be very useful to improve the knowledge and behavior of students.
