There are many factors that cause caries. This cross sectional study is to describe
the relationship of oral hygience, dietary intake with caries experience among
UKM students. A total of 93 subjects (19 - 24 years old) participated in the
study. A food record for 3 days was used to assess fluoride ingestion from diet.
Fluoride Ion Selective Electrode was used to analyse fluoride content in foods
and beverages consumed. Foods frequency questionaires (ffq) were used to
assess frequency of sugary foods intake and calcium ingestion. Oral health
questionaire was used to assess the oral hygience status. DMFT (Decayed,
Missing, Filled teeth) index was used to describe the rate and accumulation of
caries in permanent teeth. Results showed only 20.4% of subjects were caries
free. The mean DMFT score was 3.80. The mean score for filled component was
the highest (1.88), followed by decayed component (1.64) and missing
component (0.27). The mean of fluoride and calcium ingestion per day were
2.13± + 0.96 mg and 454.79 + 208.9 mg respectively. Mean daily frequency of
sugary food comsumption was 2 times. The range of fluoride content in foods
and beverages were 0.04 to 25.64 ppm and 0.03 to 0.72 ppm respectively.
There were no significant relationship between fluoride, calcium ingestion
and frequency of sugary foods intake with caries experience. There was a
statistically significant relationship between oral hygience practices and caries
experience. (p < 0.05).

A validated screening tool for patient triage based on the pain symptoms, could potentially optimize the
resources and expertise available in dental pain management. The aim of this study was to translate and
validate the Modified Dental Pain Questionnaire (M-DePaQ) for use in categorizing patients with pain into
three groups of common dental conditions. Forward Malay and Chinese translation was performed, followed
by backward English translation. The translation was reviewed by an expert panel and pre-tested on patients
who are native speakers. Consecutive patients aged 18 years and older experiencing pain and attending the
primary dental care clinic completed the questionnaires. Four calibrated dentists made clinical diagnoses
independent of the questionnaire responses. For data analysis, the cases were split randomly into Random
Sample 1 (RS1) and Random Sample 2 (RS2). Discriminant analysis was performed on RS1 to develop a model
for classifying dental pain cases into three groups. The model was applied to cases in RS2, and a crossvalidated
accuracy rate was obtained. Criterion validity was assessed using measures such as sensitivity,
specificity, positive predictive value, and kappa. Of the 234 questionnaires distributed, 216 (92.3%) were
returned. Classification rates were recorded at 73.8% for RS1, 75.0% for RS2, and 71.1% for all cases. The
sensitivity values were 0.72, 0.39, and 0.43 for Groups 1, 2, and 3, respectively. The corresponding
specificity values were 0.42, 0.87, and 0.94. The discriminant validity of the adapted questionnaire was
satisfactory, but the criterion validity could not be established because of biases incorporated in the study.

Epigenetics involved in multiple normal cellular processes. Previous research have revealed the role of hepatitis C virus infection in accelerating methylation process and affecting response to treatment in chronic hepatitis patients. This work aimed to elucidate the role of promoter methylation (PM) in response to antiviral therapy, and its contribution to the development of fibrosis through hepatocarcinogenesis-related genes. A total of 159 chronic hepatitis Egyptian patients versus 100 healthy control group were included. The methylation profile of a panel 9 genes (SFRP1, p14, p73, APC, DAPK, RASSF1A, LINE1, O6MGMT, and p16) was detected in patients’ plasma using methylation-specific polymerase chain reaction (MSP). Clinical and laboratory findings were gathered for patients with combined pegylated interferon and ribavirin antiviral therapy. Regarding the patients’ response to antiviral therapy, the percentage of non-responders for APC, O6MGMT, RASSF1A, SFRP1, and p16 methylated genes were significantly higher versus responders (P<0.05). Of the 159 included patients, the most frequent methylated genes were SFRP1 (102/159), followed by p16 (100/159), RASSF1A (98/159), then LINE1 (81/159), P73 (81/159), APC (78/159), DAPK (66/159), O6MGMT (66/159), and p14 (54/159). A total of 67/98 (68.4%) cases of RASSF1A methylated gene (P=0.0.024), and 62/100 (62%) cases of P16 methylated gene (P=0.03) were associated with mild-degree fibrosis. To recapitulate, the PM of SFRP1, APC, RASSF1A, O6MGMT, and p16 genes increases in chronic hepatitis C patients, and can affect patients’ response to antiviral therapy. The RASSF1A and P16 genes might have a role in the distinction between mild and marked fibrosis.

The effectiveness of a dental curriculum as reflected by the competencies of the graduates is paramount in ensuring its
relevance in the rapidly evolving field of dentistry. This work aimed to assess the competencies of dental graduates of
the Faculty of Dentistry, Universiti Kebangsaan Malaysia (UKM) as perceived by the graduates and their employers on
the basis of the core competencies listed in the undergraduate dental curriculum. A self-administered questionnaire
consisting of 43 questions based on eight competency domains were sent to all UKM dental graduates of years 2012 to
2015 and to senior dental officers who represented their employers. The eight domains assessed were as follows: 1)
gathering information at chair-side, 2) diagnosis, 3) treatment planning, 4) treatment and prevention, 5) communitybased, 6) management and administrative, 7) communication and 8) personal management and professional development.
a total of 132 graduates (75%) and 18 employers (55%) responded. Only domain E on community-based skills was
collectively rated ‘satisfactory’ while the rest of the seven domains had an ‘excellent’ rating by all respondents. With
regard to individual skill, basic life support was rated very low for both groups (38.6% graduates and 23.5% employers).
A strong association was found between the scores given by the graduates and their employers (p= 0.00). Generally, no
difference was found between the scores of graduates from different years. The findings allow an evaluation of the
curriculum in a myriad of angles. Although the graduates reported a good level of competency in most domains, the
employers were reserved on the community-based skills. Poor competency in the key skill of basic life support in medical
emergencies was highlighted and must be addressed in the curriculum or during training at the workplace.

Dental Practicality Index (DPI) and American Association of Endodontists Endodontic Case Difficulty
Assessment (AAECDA) form potentially can guide clinicians in making clinical decisions and triaging in
large practices and academic settings. Nonetheless, the reliability and validity should be evaluated before institution-wide implementation. This study aimed to evaluate the inter-rater reliability of the DPI and AAECDA forms. Ten randomly selected, trained students rated 25 cases with both forms. The itemby- item inter-rater and overall reliability were estimated with Gwet’s agreement coefficient (AC2) and intraclass correlation coefficient (ICC), respectively. The association between clinical decisions and the scores was analysed with the Generalised Estimating Equation. The inter-rater reliability of DPI was generally very good (AC2 = 0.81–1.00), except context (good; AC2 = 0.718; 95% confidence interval [CI] = 0.575–0.861). The inter-rater reliability of AAECDA was generally very good (AC2 = 0.81–1.00) and good (AC2 = 0.61–0.80), except the radiographic appearance of the canal(s) (fair; AC2 = 0.424, 95% CI = 0.263–0.585). Moderate overall inter-rater reliability of AAECDA (ICC = 0.53, 95% CI = 0.38–0.70) and DPI (ICC = 0.62, 95% CI = 0.48–0.77) was observed. Referral to an endodontist was positively associated with AAECDA score (odds ratio [OR] = 1.323, 95% CI = 1.145–1.52, p < 0.001). The decision of tooth extraction was positively associated with the DPI score (OR = 1.983, 95% CI = 1.539–2.555; p < 0.001). In conclusion, DPI and AAECDA are methods with moderate inter-rater
reliability when used among dental students.

A fractured instrument is an undesirable endodontic mishap that can prevent complete root canal disinfection, thereby affecting the root canal treatment outcome. The present case discussed the surgical
management of an extruded fractured barbed broach at the apical third of maxillary right first premolar.
A 28-year-old female presented with an endodontic failure on tooth 14 and was diagnosed as previously
root canal treated with symptomatic apical periodontitis. Radiographic examination revealed a straightline
radiopacity structure that was 2 mm in length extruded from the apical root-end, suggesting a fractured instrument. The case was successfully managed through endodontic microsurgery. The present case emphasises the significance of cone-beam computed tomography as a valuable tool for diagnosis and investigation, while also offering supplementary information for the planning of surgical treatment.
