Dental caries is a commonly progressive disease that proceeds through various degrees of severity that a dentist can detect. The aims of the in vivo study were to assess the accuracy of the individual model (near-infrared light transillumination [NILT] device, visual and radiographic examinations) in detecting occlusal caries, and to evaluate the performance of visual and NILT device combination for occlusal caries detection in deciding the treatment options. Fifty-two non-cavitated occlusal surfaces from 16 patients were assessed with three different diagnostic devices in random order. Identified lesions were prepared and validated. Logistic regression analysis was performed for each method. The sensitivity and specificity values for each method and the combined models were statistically measured using RStudio version 0.97.551. At the enamel level, visual detection was the most sensitive method (0.88), while NILT was the most specific (0.93). NILT scored the highest for sensitivity (0.93) at the dentine level and visual detection scored the highest for specificity (0.88). Visual detection + NILT model was significantly better (p = 0.04) compared to visual detection or NILT alone (df = 1). The visual-NILT combination is a superior model in detecting occlusal caries on permanent teeth. The model provided surplus value in caries detection hence improving the treatment decision-making in occlusal surfaces.

Acromegaly is a devastating chronic slowly progressive disease. Its early diagnosis is a challenging issue that necessitates clinical suspicion of signs and symptoms as a first step. This report introduces an unusual early sign in the oral cavity that lead to the early diagnosis of an acromegaly case. A case of a healthy 40-year-old male patient presented with progressively growing multiple hard swellings in the upper and lower jaws. Clinical examination revealed bony hard multiple small spiky exostosis-like swellings, located at the maxillary and mandibular alveolar bones. An array of investigations revealed a 2-mm diameter pituitary tumour in MRI of sella. To the best of the author’s knowledge, this is the first report of spiky exostosis-like growths in the alveolar bone as an early sign of acromegaly. In this case, thorough examination of oral signs and symptoms was the first step for early diagnosis and hence, better prognosis for acromegaly.

The study aimed to quantify the impact of lockdown during the COVID-19 pandemic on new case referrals to the Oral and Maxillofacial Surgery (OMS) service. The researchers retrospectively reviewed all new referrals received during a government-imposed 47-day lockdown period and a similar period pre-lockdown as a control group. The main outcome was the differences in the number of new case referrals between the two periods. The contributing clinical and demographic factors were also explored. Appropriate bivariate statistics were computed and the level of significance was set at 0.05 for all tests. A total of 309 referrals were received during the study period. There was a reduction of new referrals due to the lockdown from five to two cases per day. There was a statistically significant reduction of cases referred from outpatient and emergency departments. There was also a statistically significant difference with regard to home address distance to the centre. Medically compromised and orofacial infection referrals were not affected by lockdown. The lockdown imposed due to the pandemic has significantly impacted the pattern of new OMS referrals. Referrals for orofacial infections, the medically compromised and inpatients were minimally affected by lockdown.

Kimura disease (KD) is a rare chronic inflammatory disorder of unknown aetiology that primarily affects the head and neck region with lymph node involvement. Young to middle-aged adult Asian males are predominantly affected. The most common presentation is painless subcutaneous swelling in the head and neck region, while proptosis or orbital involvement is very rarely reported. KD shares some features with other inflammatory and neoplastic disorders, including lymphoma; thus, investigations to confirm the diagnosis should not be delayed. Systemic corticosteroids are commonly used to treat KD and show an excellent response; however, the optimal treatment is still uncertain, and KD has a high recurrence rate. We describe the case of a patient with KD who presented with proptosis and post-auricular swelling, which responded well to oral prednisolone treatment.

Educational landscape has changed drastically over the past decades with the integration of technology to support the role of educators. The objectives of this study were to examine the use of social media application among dental students and to investigate significant demographic variables with regard to social media use for academic purposes. All dental students across all academic years were invited to participate in a self-administered questionnaire (content validated, pre-tested) survey conducted online via Google Forms. Overall response rate was 67.8%. Of the 244 respondents, 99.1% owned smartphones, with a majority of them were iPhone and Android users. Notably, 91.4% of the respondents had access to internet data via a third generation (3G) mobile carrier and WiFi connection. A majority of the respondents (97.1%) used social media to communicate or connect with friends whereas 5.7% of them used it for business purposes. There was no significant association between gender, year of study and type of internet access with the mean of social media usage for academic purposes (p > 0.05). Most of the respondents preferred YouTube (74.6%) and Google (73.7%) for seeking information in their study. In conclusion, we found that majority of respondents had acknowledged the importance of social media in education. Our findings suggest the potential value of integrating social media in teaching and learning activities to enhance students’ learning experience.

Thalassemia is an inherited disorder that involves abnormal haemoglobin formation. This cross-sectional study with universal sampling was conducted from May 2018 to January 2019 to evaluate the oral health status of children with thalassaemia. The sample consisted of 54 transfusion-dependent patients between the ages of 3–17 years old, who were registered at the paediatric day-care centre of Hospital Melaka. Oral health status was evaluated which included soft tissue examination, recording of dental caries, malocclusion and oral hygiene status of the children, while their parents answered a pre-validated self-administered questionnaire on sociodemographic and oral health practices and attitudes. The mean deft (decayed, exfoliated and filled teeth) among the 3–5 years old was 6.71±6.07. The mean DMFT (decayed, missing and filled teeth) was 3.00±3.94 among the 13–17 years old and 1.12±1.42 among the 6–12 years old. Most of the 3–5 years old children exhibited good oral hygiene (71.4%). Dentofacial findings among the 3–5 years old were increased overjet (35.7%) and open bite (28.6%) predominantly. Fractured teeth (69.2%), increased overjet (46.2%) and discolouration (23.1%) were the common dentofacial findings among the 6–12 years old while increased overjet (71.4%), soft tissue lesions (57.1%) and posterior crossbite (28.6%) were seen among the 13–17 years old. In this cohort of children with thalassaemia, the prevalence of dental caries was high in preschool children and older children.

The present study aimed to evaluate the surface electromyography (sEMG) activity of the masseter muscles in patients with a history of temporomandibular joint disorder (TMJD) who received orthodontic treatment. In total, 22 participants aged 18–35 years old were included in this study. They were divided into the control group (patients without a history of TMJD [n = 11]) and the test group (those with a history of TMJD [n = 11]). Each participant underwent sEMG of the right and left masseter muscles at 5-s maximum voluntary contraction (MVC). Results showed that the TMJD group had a lower sEMG activity of masseter muscles at MVC than the non-TMJD group. However, the differences were not statistically significant (p > 0.05, t-test). The Spearman’s correlation coefficient test revealed a weak negative correlation between muscle activity on sEMG and history of TMJD (p > 0.05). In conclusion, orthodontically treated patients in TMJD group have reduced masseter muscle activity during MVC, compare to the non-TMJD group.

This hospital-based cross-sectional study aimed at determining frequency and risk indicators/predictors of periodontitis in a sample of Egyptian adult population and to develop a prediction equation for classifying periodontal diseases. Seven hundred and fifty subjects were consecutively recruited from outpatient Diagnostic Center, Faculty of Dentistry, Cairo University. Validated oral health questionnaire for adults and oral health impact profile-14 (OHIP-14) questionnaire were filled by all patients. Diagnosis was made based on measurements of clinical periodontal parameters including plaque index, bleeding on probing, pocket depth, clinical attachment level and gingival recession. Radiographic examination was performed using digital periapical radiographs. Ordinal logistic regression analysis was used to determine significant predictors of periodontal diseases and discriminant analysis was performed to predict periodontal disease classification. Gingivitis was the most frequent periodontal disease (39.6%) followed by periodontitis stage I (38%), stage II (20.4%), stage III (1.6%) and stage IV (0.4%). The lowest OHIP-14 scores were in patients with periodontitis stages III and IV. Multivariate analysis showed that education (p < 0.001), OHIP-14 score (p = 0.003), non-smoking (p = 0.001) and non-alcohol drinking (p = 0.021) were significant negative predictors, while never to clean the teeth (p < 0.001) were significant positive predictors of periodontal disease. Periodontitis stages III and IV were the least frequent on a sample of Egyptian adult patients. Education, frequency of teeth cleaning, smoking, alcohol drinking and OHIP-14 scores were significant predictors of periodontal disease. Through discriminant analysis this study could classify patients into different periodontal diseases with an overall correct prediction of 99.2%.

High viscous glass ionomer cement (HVGIC) was recently developed for atraumatic restorative treatment (ART). However, its moisture sensitivity remains a limitation thus protective coating application is recommended. This study investigated the effect of resin coating on the surface roughness and microhardness of two HVGICs (Riva Self Cure HVGIC [RV] and Equia® Forte Fil [EQ]) conditioned in food-simulating liquids (FSLs). Fifty standard disc-shaped samples were fabricated using customised stainless-steel mould (10 × 2 mm). Coating was applied on top surface of all samples and subsequently divided into five groups: air (control), distilled water, 0.02 N citric acid, heptane and 50% ethanol-water solution. The samples were conditioned in FSLs at 37°C for seven days. Subsequently, the surface roughness and microhardness of samples were measured using optical profilometry and microhardness tester, respectively. SEM analysis was done for qualitative observation of surface morphological changes. Data were analysed using one-way ANOVA, two-way ANOVA and posthoc Tukey’s test (α = 0.05). Interestingly, the results revealed that surface roughness was significantly influenced by FSLs immersion, presence of coating and the materials itself (p < 0.001). The lowest surface roughness was found on control coated samples: RV (50.98±4.25) nm and EQ (62.77±3.92) nm, while the highest values seen on uncoated surfaces in citric acid: RV (505.26±31.10) nm and EQ (350.33±15.36) nm. RV samples had the lowest microhardness of 54.97±2.48 Vickers hardness number (VHN) post-immersion in citric acid. In conclusion, with the exception of RV conditioned in heptane and ethanol, the uncoated HVGICs generally had higher surface roughness than the coated HVGICs. HVGICs conditioned in citric acid showed the most significant increase in surface roughness and reduction in microhardness.

This study aimed to determine the fluoride and pH levels of beverages likely to be consumed by children in Malaysia and to estimate daily fluoride intake from consumption of these beverages. A convenience sampling of 120 ready-to-drink beverages were purchased and categorised into 11 groups (UHT recombined milk, fresh milk [pasteurised], cultured milk [probiotic], yogurt beverages, fresh fruit juices, fruit flavoured beverages, soy-based beverages, malt-based beverages, tea, carbonated beverages and bottled waters). Fluoride concentration was measured using a fluoride ion-selective electrode while the pH level was measured using a pH meter. The fluoride concentration in the beverages ranged from 0.02±0.00 mg/L to 2.77±0.06 mg/L. Tea was found to have the highest fluoride concentration. The intake of fluoride from consumption of other types of beverages is below the lowest-observed-adverseeffect level (except tea). The pH of the beverages included in the study ranged from 2.20±0.01 to 7.76±0.00. Carbonated beverages (mean pH: 2.98±0.50) were found to be extremely acidic followed by fresh fruit juices (mean pH: 3.38±0.34) and fruit flavoured beverages (mean pH: 3.90±0.92). The correlation between fluoride and pH levels was weak, τ = 0.058 and not statistically significant (p
