Prevalence of dental caries in primary and permanent teeth and its relation with tooth brushing habits among schoolchildren in Eastern Saudi Arabia

Objectives: To determine the prevalence of dental caries in the primary and permanent teeth, and evaluate the brushing habits of school children in Dammam, Kingdom of Saudi Arabia (KSA). Methods: This study was conducted at Dammam, KSA. Oral examination of the participants was conducted from February to May 2014. The total sample size for this cross-sectional study was 711. There were 397 children between the age of 6-9 years, who were examined for primary teeth caries, and 314 between the age 10-12 years were examined for permanent teeth caries. Primary and permanent dentitions were studied for decayed, missing, and filled teeth (dmft [primary teeth], DMFT [permanent teeth]). Results: The overall prevalence of dental caries in primary and permanent teeth was almost 73% (n=711). Among the 6-9-year-old, the prevalence of caries was approximately 78% (n=397) whereas, among the 10-12-year-old children, it was approximately 68% (n=314). Mean dmft value among the 6-9-year-olds was 3.66±3.13 with decayed (d) component of 3.28±2.92, missing (m) component of 0.11±0.69, and filled (f) component of 0.26±0.9. Mean DMFT value among the 10-12-year-old children was 1.94±2.0 with decayed (D) component of 1.76±1.85, missing (M) component of 0.03±0.22, and filled (F) of component 0.15±0.73. Daily tooth brushing had a positive effect on caries prevention, and this effect was statistically significant for caries in primary teeth. Conclusion: Although the prevalence of dental caries in primary and permanent teeth was not found to be as high as other researchers reported from different cities of KSA, still the prevalence was high considering the World Health Organization future oral health goals. Awareness should be provided to students, as well as, teachers and parents regarding the importance of good brushing habits and regular dental visits.

Effect of software facilitated teaching on final grades of dental students in a dental morphology course

Objectives: To evaluate differences in students’ performance in a dental morphology course after the introduction of a 3D software-teaching program. Methods: This retrospective study took place at the College of Dentistry, University of Dammam, Dammam, Kingdom of Saudi Arabia, from Augst 2013 to January 2016. The study included 3 groups of students taking the course during 3 different academic years: group 1, 2013-14 control; group 2, 2014-2015; and group 3, 2015-2016. The total sample size was 294 (n = 294; group 1 = 94; group 2 = 100; and group 3 = 100). Group 1 =students did not receive teaching facilitated by a software program, but groups 2 and 3 students were provided with the program’s CDs. The final examination grades of the students were statistically analyzed, retrospectively Results: The results demonstrated that the students who received software-facilitated teaching (groups 2 and 3) performed better than the students who did not receive it (group 1). Within the same year for groups 2 and 3, the number of students achieving good grades (>80%) was significantly higher than the students who achieved average grades (<79%), with p-values of 0.012 for group 2 and 0.009 for group 3. Conclusion: There is a positive correlation between the use of a teaching software program for students and their performance in final examinations. The addition of computer-based learning, as one of the teaching methods, could demonstrably boost students’ learning.

Attitude and experiences of undergraduate dental students and interns towards research

Objective: This study was designed to evaluate the perception of students and interns toward research. Materials and Methods: The study was conducted in January 2014. Participants of the study were fourth, fifth, and 6 th year students and interns. A questionnaire comprised thirteen questions was distributed to evaluate students′ and interns′ perception about the importance of research in their learning. Results: The results showed that interns and 6 th year students were more interested in research as compared to their junior counterparts as they realized the importance of research in their educational growth. This was reflected by the number of interns who completed the questionnaire. Conclusion: Dental students realized the importance of research in the education, but it was found that the proportion of students who did research as part of their course was very low. Students should be actively engaged in research, which can be achieved by introducing research as a compulsory component of their course.

Frequency of root canal treatment among patients attending a teaching dental hospital in Dammam, Saudi Arabia

Objective: The purpose of the study was to evaluate the frequency and status of root canal-treated teeth in patients treated at the College of Dentistry, University of Dammam in the Eastern Province of Saudi Arabia. Materials and Methods: A total of 3701 patients visited the clinics during the study period. Through the use of radiographs, 161 patients were initially selected who had endodontically treated teeth. However, after applying the inclusion criteria, the total number of eligible cases was reduced to 155. Patients were divided into three groups according to age (children 1–12 years, adults 13–65 years and geriatrics >65 years). Results: On average, each patient had 2.28 ± 1.88 root canal-treated teeth and 24.02 ± 5.03 teeth without root canal treatment. The average number of endodontically treated teeth increased with an increase in age. The adult group showed the highest number of root-filled teeth 314 (93.4%). Of the 336 endodontically treated teeth, only 75 (22.3%) teeth exhibited periapical radiolucency. First molars (28.43–36.36%) and second premolars (20.1–27.27%) were the most frequently root-filled teeth in both jaws, followed by the first maxillary premolars (11.76%). Periapical lesions showed an almost similar pattern with the highest number of radiolucencies found in the first molars in both jaws (29.3–33.3%) followed by the second premolars in the mandible (30.6%) and first premolars in both jaws (20.8–25%). Conclusion: The first molars and second premolars were the most frequently root-filled teeth in both jaws, followed by maxillary first premolars. Periapical lesions showed an almost similar pattern among teeth with a higher number of radiolucencies found in the first molars in both jaws, followed by the second premolars in the mandible and the first premolars in both jaws.

Prevalence of dental fluorosis in school going children of Dammam, Saudi Arabia

Objective: Purpose of the study was to determine the prevalence of dental fluorosis and its pattern in primary and permanent teeth among 6-12-year-old Pakistani school going children living in Dammam, Saudi Arabia. Materials and Methods: This cross-sectional study was performed between June and September 2014. A total number of screened children were 496 among them 259 were males and 237 were females. World Health Organization′s scale was used to examine children for dental fluorosis. Results: Prevalence of dental fluorosis was found to be 33% among a total number of examined children. Among the children who had dental fluorosis (n = 164), it was observed that mild and moderate level of fluorosis were prevailing in 113 (69%) children. Furthermore, a number of males who were suffering from fluorosis was more than the females. There were 97 males and 67 females found affected from dental fluorosis and this difference was found statistically significant (P = 0.038). Conclusion: Prevalence of dental fluorosis among Pakistani school going children was not high. However, the severity of fluorosis was alarming, mild, and a moderate level of fluorosis was observed in most of the children who were affected from fluorosis.
