    This prospective study investigated the difference in clinical efficiency between Damon™ 3 self-ligating brackets (SLB) compared with Mini Diamond conventional ligating brackets (CLBs) during tooth alignment in straightwire fixed appliance therapy. Twenty-nine patients (10 males and 19 females), aged between 14 and 30 years, were randomly divided into two groups: 14 patients received the SLB and 15 received the CLB. Upper arch impressions were taken for pre-treatment records (T(0)). A transpalatal arch was soldered to both maxillary first molar bands prior to extraction of the maxillary first premolars, followed by straightwire fixed appliances (0.022 × 0.028 inch). A 0.014 inch nickel titanium (NiTi) wire was used as the levelling and aligning archwire. Four monthly reviews were undertaken and impressions of the upper arch were taken at each appointment (T(1), T(2), T(3), and T(4)). Displacements of the teeth were determined using Little's irregularity index (LII). Data were analysed using the Mann-Whitney U-test. In the aligning stage, the CLB group showed significantly faster alignment of the teeth compared with the SLB group at the T(1)-T(2) interval (P < 0.05). However, there were no differences at T(2)-T(3), and T(3)-T(4) for either group (P > 0.05). The CLB group showed 98 per cent crowding alleviation compared with 67 per cent for the SLB after 4 months of alignment and levelling. Mini Diamond brackets aligned the teeth faster than Damon™ 3 but only during the first month. There was no difference in efficacy between the two groups in the later 3 weeks. Alleviation of crowding was faster with CLB than with SLB.

    AIM: This study aimed to evaluate the oral health-related quality of life (OHRQoL) among older persons in Malaysia and its associations with sociodemographic and self-perception towards general health as well as oral health.

    METHODS: A cross-sectional survey among community dwelling older persons utilizing stratified cluster sampling was conducted in 2018. Well-trained interviewers conducted a face-to-face interview with older persons aged ≥60 years to collect information on participants' sociodemographic characteristics, self-perception on general as well as oral health using the Geriatric Oral Health Assessment Index (GOHAI). Multivariate analysis of the data collected was performed using SPSS version 23.

    RESULTS: Overall, the GOHAI mean ± SD score for older persons in Malaysia was 51.83 ± 7.98, which was an average of fair mean (P

    INTRODUCTION: Inadequate toothbrushing practice is define as brushing teeth less than two times per day. Inadequate toothbrushing during adolescence can lead to oral health problems and disease burden in adults. Moreover, inadequate practice can lead to low quality of life and inadequate self-esteem.

    OBJECTIVE: This study aimed to determine the prevalence of inadequate toothbrushing practice among adolescents aged 13 to 17 years in Malaysia and its association with sociodemographic and other related risky lifestyles.

    METHOD: This study was part of a national cross-sectional study, Global School Health Survey 2017. 27,497 students were agreed to participate in this study, with response of 89.2%. A validated self-administered bilingual, comprised of topics related to sociodemographic as well as adolescent health and risky lifestyles; substance use (alcohol, drug, smoking cigarettes), eating patterns, hygiene (inclusive of oral and hand hygiene), mental health status, lack of peer and parental/guardian support, truancy, physical activity, and body mass index (BMI). Analysis was performed using IBM SPSS for Windows version 26.0 involving complex sampling analysis and logistic regression.

    RESULTS: A total of 12.7% (95% CI: 11.8-13.6) of in-school adolescents had inadequate toothbrushing practices. Higher prevalence of inadequate toothbrushing were found among male, Indian, had ever drug use, had three or more lack of protective factors and had inadequate hand hygiene practices. Adolescents who had inadequate toothbrushing were significantly higher odd among males, Indian ethnic, ever drug use, inadequate hand hygiene practices and adolescents who had three or more lack of peer and parental/guardian support.

    CONCLUSION: Approximately 1 out of 10 adolescents had inadequate toothbrushing practices with several factors associated, such as male gender, Indian ethnicity, inadequate hand hygiene, ever drug use and lack of protective factors are identified to be associated. By emphasizing the significance of frequent brushing, we can encourage positive changes and reduce the burden of preventable dental problems on adolescents.

    OBJECTIVE: To assess the perceptions of caregivers towards oral healthcare services received by elders in Malaysian nursing homes and to identify challenges and suggestions for improvement.

    BACKGROUND: Caregivers play an important role in the oral health care of elders in nursing homes.

    METHODS: This study employed a qualitative approach using the nominal group technique (NGT) to obtain caregivers' feedback in nursing homes in Malaysia. Data were manually transcribed, summarised into keywords/key phrases, and ranked using weighted scores.

    RESULTS: In total, 36 caregivers (21 from government and 15 from private nursing homes) participated in the NGT sessions. Overall, caregivers were satisfied with the low treatment cost, the quality of treatment, and the availability of dental visits to nursing homes. Caregivers were dissatisfied with the frequency of dental visits, long waiting times at government dental clinics, and inadequate denture hygiene education for elders in nursing homes. The challenges faced by caregivers were elders' poor oral health knowledge and attitude and lack of elders' trust of caregivers to look after their oral health. Suggestions for improvement were to increase the frequency of dental visits to nursing homes, provide oral health education to elders and caregivers, and give treatment priority to elders at dental clinics.

    CONCLUSION: Despite being satisfied with the basic oral healthcare services received by elders in Malaysian nursing homes, caregivers raised some issues that required further attention. Suggestions for improvement include policy changes in nursing home dental visits and treatment priority for elders at government dental clinics.
