Maxillofacial fracture is the most common form of injury in trauma patients, especially in patients with motor vehicle accidents. The COVID-19 pandemic has affected various sectors, including restrictions on people's mobility. This study aims to determine the profile of patients with maxillofacial fractures during the COVID-19 pandemic. A descriptive observational study was conducted to evaluate maxillofacial fracture patients who came to the Emergency Department of the Head-Neck Surgery Division of the Dr. Soetomo Surabaya Hospital in 2020. Subjects were grouped according to sex, age, month of visit and the mechanism of trauma. The ratio between men and women was 4.92:1. The largest age distribution is in the 11-20 years range, as much as 39.2%. The most distribution based on the month of visit was in February as much as 16.9%. Most trauma mechanisms were due to traffic accidents (90.1%). Most locations in single maxillofacial fractures in maxillary bone were 37.8% and multiple maxillofacial fractures in zygoma bones were 79.4%. Accompanying trauma was found in 73.2% of subjects, with the highest pattern of intracranial trauma as much as 80.8%. The incidence of single maxillofacial fractures was 47.9% and multiple maxillofacial fractures were 52.1%, with concomitant trauma occurring in 73.2% of subjects.

Deletions and amplifications of genes often occur during multistep progression from oral precancer, seen as oral epithelial dysplasia (OED) to cancerous stage. These genetic alterations could be used as markers to aid in detection of oral squamous cell carcinomas (OSCC). This study explored the use of multiplex ligation-dependent probe amplification (MLPA) technique in detecting OSCC and OED specific genetic alterations. MLPA was used to detect gains and losses of 106 genes in DNA extracted from frozen tissue samples of 10 OSCC and 10 non-cancer patients. Two biopsies of OED were analyzed to explore the alterations in oral potentially malignant disorders. There were significant differences (p<0.001) in the number of alterations in OSCC and dysplasia compared to non-cancer samples respectively. The most frequently altered genes in OSCC were PTP4A3, RECQL4, ATM, and KLK3 (60%). Five genes (MYC, SLA, TNFRSF1A, MESDC1, MIF) were altered in 50% of OSCC samples. These nine genes were specific to OSCC samples (p<0.05). Some genes, including MYB, MET, CASP2, SLA and PTEN occurred in 50% of OED samples. MLPA was able to detect genetic alterations, that are present only in OSCC samples and showed potential to be used as an adjunctive tool in early diagnosis of OSCC.

As a means to combat the coronavirus disease (COVID-19) global pandemic, educational institutes were forced to stop the accustomed face-to-face teaching methods and adopt an online scheme to ensure the continuity of the education process. Furthermore, only a minimal period of clinical training was offered to the students during the pandemic and this highlighted the critical need to expand and improve the dental simulation curriculum. This article aims to highlight the impact of COVID-19 pandemic on the students and educators in dental schools. This perspective paper will also discuss the effectiveness of online teaching and the challenges in learning environment at the Faculty of Dentistry, Universiti Malaya during the pandemic, based on observations and published literature.

The objective of this study was to assess misconceptions, hesitancy and efficacy of COVID-19 Vaccine among Faculty, House Officers (HO) and Postgraduates (PG) dental trainees towards the novel COVID-19 vaccine and to assess the association between COVID-19 vaccine acceptance and conspiracy beliefs. A cross sectional study was conducted on 150 participants from Sardar Begum Dental hospital, Peshawar, Khyber Pakhtunkhwa. A self-administered questionnaire was developed with questions related to perception of participants regarding misconceptions, safety, hesitancy and efficacy of COVID-19 Vaccination. The questionnaire comprised of 26 closed-ended questions. Data was analyzed using SPSS statistical package 26.0. More than half of the participants (87.3%) reported to be tested positive for COVID-19 at some point. Majority of participants (87.3%) reported that they were vaccinated and 86.7% reported that they had post-vaccination reactions such as pain in arm, fever and body aches. A notable number of participants that were part of the study believed in the misconceptions related to the COVID-19 vaccine. This study concluded that despite widespread vaccination awareness campaigns, significant number of dental surgeons believed in misconceptions regarding COVID-19 vaccination that may pose a significant challenge to Pakistan's COVID-19 immunization program.

A high presence of periodontal pathogens such as Porphyromonas gingivalis (P. gingivalis) has been found in cancers at different body locations. The imbalance of the oral microbiome (dysbiosis) promotes the chronic inflammatory process that could contribute to carcinogenesis. To assess the P. gingivalis detection in cancer patients. A search for studies on P. gingivalis and neoplasms was conducted from 1974 to 2021 in the following databases: PubMed (MEDLINE), Cochrane Library, Web of Science (WoS), and Scopus. For dichotomous outcomes, the estimates of effects of an intervention were expressed as odds ratios (OR) using Mantel-Haenszel (M-H) method with 95% confidence intervals. Funnel plot and Egger’s test for publication bias analysis were used. Also, Newcastle-Ottawa (NOS) studies methodological quality assessment scale was employed. Thirteen studies that involved 1732 cancer patients and 3298 controls without cancer were included in this meta-analysis. P. gingivalis detection was 1.81 times more likely in cancer patients (p<0.01) compared to controls. P. gingivalis detection was also more likely in patients with colorectal (OR: 2.00, p=0.02) or pancreatic (OR: 1.32, p=0.02) tumors. In contrast, oral, esophageal, lung, or breast cancers did not show a significant increase of P. gingivalis detection (p>0.05).

Full thickness skin graft is a simple and reliable method for closure of small facial wound defect. A thorough understanding of how a skin graft heals and how to perform the procedure is essential for successful outcome. We report the use of full thickness skin graft in a wound closure of a facial skin defect caused by Paederus fuscipes, locally known as charlie. An 8-year old boy developed blister and painful swelling over his right cheek following skin contact with charlie. This lesion gradually became extensive, eventually leading to tissue loss and facial wound defect. A full thickness skin grafting was performed with satisfactory functional and excellent aesthetic result.

Heat-cured PMMA is one of the most frequently used materials in the manufacture of removable dentures. Heat-cured material used to fabricate dentures contain soluble elements, allowing the material to absorb and release substances. These factors all directly affect the longevity and performance of protheses fabricated from polymethyl methacrylate denture base material. Various procedures associated with fabrication of removable dentures from heat-cure denture base material are reported to significantly influence the sorption and solubility experienced by the prosthesis. A comprehensive search of peer-reviewed journals located within academic databases was conducted to identify relevant literature pertaining to sorption and solubility of denture base materials. Key aspects of each paper were captured in Microsoft® Excel® to record author/s, location, study design, sample size, methodology, results and conclusions. Mixing ratios and polymerisation cycles have been identified as variables that can negatively influence the rate of sorption and solubility of denture base materials during the fabrication process. Certain surface treatment procedures, as well as storing the denture in artificial saliva solution may reduce the levels of sorption and solubility experienced and optimise its lifespan. In this review we identify these factors and consider the detrimental effects of sorption and solubility on denture base acrylic materials.

The placement of glass ionomer cement as lining material below composite fillings was introduced by McLean and Wilson in 1977. This technique incorporated different layers of restorative materials placed onto tooth, similar to layers of a sandwich. It was proposed this technique will provide a molecular seal to dentine in addition to mechanical and aesthetic properties of composite resin. Placement of liner or an intermediate layer underneath the main bulk of restorative materials reduces polymerization shrinkage stress and resultant microleakage of the final restoration. To date, dentine adhesion and polymerization shrinkage are limitations of resin-based restorative materials. At present, wide array of tooth-coloured restorative materials with different formulations is available. Despite advancements in restorative dentistry, no single technique or material is ideal in both clinical effectiveness and simplicity. Clinicians may find themselves in a dilemma when choosing restorative materials and techniques that provide the best clinical results with minimal technique sensitivity or chairside time. The aim of this review is to present existing scientific evidence in microleakage and sandwich technique in restorations, and to discuss multiple approaches in sandwich restorations in effort to reduce microleakage of dental restorations. Clinical recommendations will be given based on evidence from multiple studies.

This study aims to compare flexural strength and flexural modulus of different resin-based composites (RBCs) and to determine the impact of dietary solvents on flexural properties. Forty specimens (12x2x2mm) for each of two conventional (Aura Easy [AE]; Harmonize [HN]) and one bulk fill (Sonic Fill 2 [SF2]) were fabricated using customised plastic moulds. Specimens were light-cured, measured and randomly divided into four groups. The groups (n=10) were conditioned for 7 days at 37°C: in one of media: air (control), artificial saliva (SAGF), 0.02N citric acid and 50% ethanol–water solution. After conditioning, the specimens subjected to flexural testing. Two-way ANOVA and one-way ANOVA (post hoc: Tukey’s or Dunnett T3 tests) were used at a=0.05. Significant differences in flexural properties were observed between materials and conditioning media. Flexural strength and modulus values ranged from 124.85MPa to 51.25MPa; and 6.76GPa to 4.03GPa, respectively. The highest flexural properties were obtained with conditioning in air. Exposure to aqueous solutions generally reduced flexural properties. In conclusion, the effect of dietary solvents on flexural properties were material and medium dependent. For functional longevity of restorations, patients’ alcohol intake should be considered during material selection. Dietary advice (reduce alcohol consumption) should be given to patients post operatively.
