Aims:To evaluate the self-perceived preparedness of final-year dental undergraduate students in dental public universities in Malaysia. Methods:Final-year dental undergraduate students from six dental public universities in Malaysia were invited to participate in an online study using a validated DentalUndergraduates Preparedness Assessment Scale DU-PAS. Results:In total, about 245 students responded to the online questionnaire yielding a response rate of 83.05%. The age range of the respondents was 23-29 years with a mean age of 24.36 (SD 0.797). The total score obtained by the respondents was ranged from 48 to 100 with a mean score of 79.56 (SD 13.495). Weaknesses were reported in several clinical skills, cognitive and behavioural attributes.

BackgroundNeonatal teeth erupt during the neonatal period and natal teeth are the presence of teeth since birth. While rare, natal teeth and neonatal teeth can have a significant impact on breastfeeding. Neonatal teeth are less common, and although its exact etiology is still unknown, it can cause difficulties in breastfeeding to the mother and may eventually lead to discontinuation of breastfeeding. Other associated possible complications include tooth aspiration and sublingual ulceration. This paper was aimed to discuss the clinical features, complications, and management of neonatal tooth, in addition to its impact on breastfeeding and role in sublingual ulcer formation.Case presentationWe present a baby girl who had a neonatal tooth with sublingual ulceration (Riga-Fede disease), which resulted in a difficulty to breastfeed for the baby and nipple pain to the mother. Following the extraction of the baby’s tooth, she immediately continued breastfeeding, and her tongue ulcer healed well.ConclusionExtraction of the neonatal tooth promoted rapid healing of oral ulcers and the reestablishment of breastfeeding.

Background Curing of resin-based composites depends on the delivery of adequate total energy, which may be operator dependent. Aim To determine the effect of interincisal opening, cavity location and operator experience on the total energy delivered to simulated cavity preparation sites. Design Three cohorts were included: junior dental nurses, senior dental nurses and qualified dentists (N=5, each cohort). Each operator (participant) followed the same procedure and light-cured two simulated restorations in a MARC® patient simulator using a Demi™ light-curing unit for 20 seconds in each of the following situations: left upper second molar (UL7), interincisal opening at both 25mm and 45mm; upper central incisor (UR1), interincisal opening at 45mm. The light energy delivered by each operator in each situation was recorded. Five readings for each operator were taken at each interincisal distance. Statistical comparisons of delivered energy (J/cm2) between interincisal openings, location and groups in the total energy delivered were performed using the Kruskal-Wallis nonparametric test: α=0.05. Results Less total energy was delivered to the posterior cavity at 25mm (12.0 ± 5.3J/cm2) than at 45mm (16.9 ± 5.6J/cm2) by all operators ( P<0.05). At 45mm, less total energy was delivered to the posterior cavity compared to the anterior cavity (25.1 ± 7.4J/cm2; P<0.05). There was no statistically significant difference between junior nurses and qualified dentists ( P>0.05) but there was a significant difference in the total energy delivered between senior nurses (20.1 ± 7.8J/cm2) and junior nurses (17.5 ± 7.6J/cm2) and between senior nurses and qualified dentists (16.6 ± 8.7J/cm2) ( P<0.05). Conclusions Interincisal mouth opening, location of the cavity and operator experience affected the total energy delivered to cavities in a simulated clinical environment.

Early childhood caries (ECC) is one of the most prevalent dental diseases among children and is related to their early feeding practices. This multi-factorial disease involves susceptible tooth and host, fermentable carbohydrates in the diet, cariogenic micro-organisms and time (American Academy of Pediatric Dentistry, 2008). Thus, this study aimed to identify the associations between bottle-feeding and weaning practices, and ECC formation. By using convenience sampling, 201 children were recruited from the IIUM Outpatient Dental Clinic and ten kindergartens around the area of Kuantan, in the state of Pahang (Malaysia). Examination for caries was conducted visually to determine caries status (with or without caries). The caregivers were requested to fill in a questionnaire regarding feeding practices of their children. The findings of the study indicated that 67% of the children identified with caries practiced bottle-feeding in bed either sometimes or always (every night/day) (p=0.005). The prevalence of ECC was also significantly (p<0.001) the highest (48.5%) among children who had been bottle-feeding for the longest duration (>4 years) among the study population. In addition, the mean intake of sweetened drinks among children with ECC was significantly higher than those with no ECC (5.4 vs. 3.1 servings/week, p=0.001). The results of this research indicated that the increased frequency and prolonged duration of bottle-feeding practices, as well as high consumption of sweet drinks during weaning, could be associated with the formation of ECC. In conclusion, these findings would increase the awareness particularly among parents regarding bottle-feeding practices and weaning diet contents and its potential implication on their children's oral health.

Aim: To investigate the depression, anxiety and stress, stressors and relieving factors among dental students at Kulliyyah of Dentistry (KOD). Materials and methods:  A cross-sectional study was conducted among 222 dental students. Their socio-demographic data, self-reported depression, anxiety and stress (DASS-21) scores, causes and relieving factors were collected using validated semi-structured pre-tested questionnaires. The data was analysed using percentages, chi-square test and Binary logistic regression tests with SPSS version 24. Results: The prevalence of depression, anxiety and stress was 41%, 68.9% and 34.2% respectively. Cross analysis showed that academic-related and laboratory or clinical related reasons were significantly associated with the depressive symptoms [(X2= 15.86, p<0.0001) and (X2= 10.45, p=0.001) respectively] and stress symptoms [(X2= 19.95, p<0.0001) and (X2= 6.11, p<0.05) respectively] among dental student. Furthermore, the item ‘examination’ being the highest factor chosen in academic-related stressors. The response for stress-relieving factors was high for Islamic ritual prayer/spiritual activities (94.6%), sleeping (86.5%) and doing exercise/playing sports (76.1%), while ‘seeking professional help’ (19.8%) was the least. Conclusion: This study shows that depressive, anxiety and stress symptoms are prevalent among dental students. Islamic ritual prayer and involvement in spiritual related activities was found to be the most preferred way for students to relief stress. Hence, it is vital that the university continually evaluates the psychological health of the students, tailor preventive measures and spiritual related programs to help students to cope with stress.

The aim of this study was to determine the prevalence and association of molar incisor hypomineralization (MIH) with perinatal complications (PC), childhood illness (CI), and prolonged antibiotic consumption (PAC) among children attended at the Polyclinic, Kulliyyah of Dentistry, IIUM. MIH was determined based on criteria from EAPD seminar, Athens 2003. Out of 156 patients, 23 were detected having MIH within the 9 months period. Analysis of risk factors indicated significant association between MIH with CI. In conclusion, MIH was not related to gender. However, MIH was associated with CI but not with PC and PAC.

The prevalence of dental erosion among children and adolescents is trending higher in recent decades and is becoming a major concern. Dental erosion can be caused by either extrinsic or intrinsic acids or both. One of the established aetiological factors for dental erosion by intrinsic acid is the gastrooesophageal reflux disease. The degree of dental erosions may be influenced by any medical conditions that cause a reduction in salivary flow such as the salivary gland excision, autoimmune disease, radiation to the head and neck regions, and medications. If left untreated, the dental erosion can cause dentine hypersensitivity, loss of occlusal vertical height, and aesthetic problems. For effective management of dental erosion, the aetiology of each case must be determined, and its detection at an early stage is of prime importance. This case report illustrates the conservative management of dental erosion in two adolescent patients presented with their medical conditions and behaviour issues. The aim of the treatments was to preserve the vitality of the affected teeth. The treatments were successfully completed using a conservative approach, with the patients' medical conditions taken into consideration.
