Eur J Dent, 2025 Feb;19(1):214-219.
PMID: 39013444 DOI: 10.1055/s-0044-1787005

OBJECTIVES: This study aimed to establish the cephalometric norms of H angle soft tissue and H angle hard tissue of Malaysian Malay adult females, and to evaluate the correlation between H angles and visual perception in skeletal Class I Malay adult females.
MATERIALS AND METHODS: Eighty-five lateral cephalograms of skeletal Class I (mean ANB value = 3.15 ± 0.77) Malaysian Malay female patients aged 20 to 40 years (mean age = 28.6 ± 5.86 degrees) taken from October 2017 to December 2021 were measured for H angle soft tissue and H angle hard tissue. Twenty silhouettes were then converted from cephalometric films and were rated according to facial convexity/concavity by 20 laypersons, with re-evaluation after 2 weeks for intra- and interexaminer reliabilities.
RESULTS: The means of the H angle soft tissue and H angle hard tissue were 15.75 ± 4.16 degrees and 11.64 ± 4.71 degrees, respectively. The intraexaminer reliability test for visual perception ranged from -0.89 to 0.99 indicating poor to excellent reliability, whereas the interexaminer reliability test was 0.82 indicating good reliability. A highly statistically significant association between the H angle soft tissue and H angle hard tissue (r = 0.938; p

SARS-CoV-2 has spread throughout the world since its discovery in China, and Malaysia is no exception. WGS has been a crucial approach in studying the evolution and genetic diversity of SARS-CoV-2 in the ongoing pandemic. Despite considerable number of SARS-CoV-2 genome sequences have been submitted to GISAID and NCBI databases, there is still scarcity of data from Malaysia. This study aims to report new Malaysian lineages of the virus, responsible for the sustained spikes in COVID-19 cases during the third wave of the pandemic. Patients with nasopharyngeal and/or oropharyngeal swabs confirmed COVID-19 positive by real-time RT-PCR with CT value < 25 were chosen for WGS. The selected SARS-CoV-2 isolates were then sequenced, characterized and analyzed along with 986 sequences of the dominant lineages of D614G variants currently circulating throughout Malaysia. The prevalence of clade GH and G formed strong ground for the presence of two Malaysian lineages of AU.2 and B.1.524 that has caused sustained spikes of cases in the country. Statistical analysis on the association of gender and age group with Malaysian lineages revealed a significant association (p <0.05). Phylogenetic analysis revealed dispersion of 41 lineages, of these, 22 lineages are still active. Mutational analysis showed presence of unique G1223C missense mutation in transmembrane domain of the spike protein. For better understanding of the SARS-CoV-2 evolution in Malaysia especially with reference to the reported lineages, large scale studies based on WGS are warranted.

STATEMENT OF PROBLEM: Denture wearers are susceptible to diseases related to denture hygiene and are more prone to develop systemic disease because of poor understanding and awareness of the impact of edentulism on general health.
PURPOSE: The purpose of this clinical study was to evaluate the effectiveness of traditional chairside practice and WhatsApp in improving patient knowledge of denture care and their awareness of the impact of edentulism on general health.
MATERIAL AND METHODS: Sixty-two participants who attended the Polyclinic Kulliyyah of Dentistry, IIUM Kuantan in 2022 for removable prosthesis fabrication were recruited. The participants were randomized into 2 groups: control (traditional chairside) and intervention (WhatsApp) group. Video intervention was sent via WhatsApp to the participants. Pretreatment and posttreatment questionnaires were distributed from March to September 2022 to survey their sociodemographic data, knowledge of denture care, and awareness of the effect of edentulism on general health. Data were obtained and checked for normality using the Shapiro-Wilk test. Data were analyzed using the Mann-Whitney U and Wilcoxon-Paired Signed-Rank tests (α=.05).
RESULTS: Eighty-two percent of participants favored WhatsApp as a tool for receiving information and used it daily (66.1%). The level of overall knowledge and awareness increased in groups after denture insertion instruction. Participants' knowledge of denture care (P=.001) and awareness of the effect of edentulism on general health (P=.001) improved significantly in the WhatsApp intervention group compared with the control group.
CONCLUSIONS: WhatsApp can be used as an alternative tool for improving denture care knowledge among denture wearers; increased awareness was observed with WhatsApp compared with the traditional chairside approach.
