Prolonged work with highly repetitious flexion and extension of the wrist and forceful grip task were shown to increase the risk of developing carpal tunnel syndrome (CTS) among dental personnel. The present study was carried out to determine the prevalence, risk factors and coping strategies of probable CTS among clinical dental support staff in Hospital Universiti Sains Malaysia (HUSM). A cross-sectional study was conducted and a set of questionnaire consisting of socio-demographic status, work-related and psychosocial risk factors and coping strategies was distributed. Ninety-five clinical dental support staff completed and returned the questionnaire with a response rate of 80.5%. The prevalence of probable CTS was 38.9%, with the highest prevalence was found among dental surgery assistants (40.5%) followed by dental technologists (29.7%). There was no significant association between work-related or psychosocial risk factors with probable CTS (p>0.05). Most of the respondents with symptoms of CTS chose religion as the coping mechanism; mean 7.11 (SD 1.13). Awareness training should be emphasized among clinical dental support staff on the prevention of CTS.
Carpal Tunnel Syndrome

ntroduction: Oral cancer is a life-threatening disease. Lack of public awareness is a potent barrier for the early detection of oral cancer, especially for high-risk populations. Objective: This study aimed to determine the awareness and knowledge of the signs, symptoms and risk factors of oral cancer among a Siamese ethnic group in Tumpat, Kelantan. Methods: A cross-sectional study was conducted, using a guided questionnaire on sociodemography, habits, awareness and knowledge of the signs, symptoms and risk factors of oral cancer. Individuals under 18 years old and who had been diagnosed with oral cancer were excluded from this study. Results: A total of 195 respondents participated, 61.5% were female and the mean age was 46 (1.64). About 41% of the respondents had received secondary education and 35.4% were illiterate. Most respondents were self-employed (21.5%), followed by farmers (19.5%) and housewives (20%). The majority of them had a monthly income that fell below the poverty level of RM 830 (76.9%). Among the respondents, 22.6% had the habit of smoking, 25.6% consumed alcohol, 8.2% were betel quid chewers and 2.6% chewed tobacco. Out of 195 respondents, only 6.7% were aware of oral cancer. About 16.9% of the respondents correctly answered all of the questions regarding the signs and symptoms of oral cancer and only 4.1% knew the risk factors of oral cancer. Conclusion: The awareness and knowledge of oral cancer in this targeted population were unsatisfactory. Future effective health promotion programs and education should be emphasised.

Introduction: Dental unit waterline system (DUWLS) decontamination is an important infection control in dental practice. This study aimed to determine knowledge and attitude towards DUWLS decontamination and its associated factors among undergraduate and postgraduate dental students in Universiti Sains Malaysia. Methods: A cross-sectional study was conducted using a validated questionnaire administered online using Google Forms to assess the knowledge and attitude of dental students towards DUWLS decontamination. Descriptive and inferential statistics using independent t-test, Pearson, and Spearman correlation were carried out using SPSS version 24.0. Results: A total of 169 dental students participated in the study, and the majority were female (71.6%) and Malay (59.2%). The mean (SD) age was 23.2 (0.93) and 34.4 (2.65), for the undergraduates and postgraduates, respectively. The mean (SD) knowledge scores for the undergraduates and postgraduates were 11.6 (4.23) and 18.0 (2.82), respectively, whereas the mean attitude scores were 51.3 (7.86) and 54.6 (4.74), respectively. The postgraduates had significantly higher mean knowledge and attitude scores than the undergraduates (p<0.001). The significant factors associated with the undergraduates’ knowledge were received information and guidance and their personal experience in managing DUWLS (p<0.05). However, only received information on DUWLS was significantly associated with the postgraduate’s knowledge score (p=0.011). Age factor had a significant association with the attitude score among the postgraduates (p=0.014). Conclusion: The knowledge regarding DUWLS decontamination was relatively moderate in both groups. However, both groups showed a favourable attitude towards DUWLS decontamination. Significantly higher knowledge and attitude scores were presented among the postgraduates than the undergraduates.

Introduction: Smoking is a common risk factor for periodontal disease and other chronic diseases. This study was conducted to determine the prevalence of smoking among army personnel and its association with periodontal health status. Methods: A cross-sectional study was carried out among randomly selected 233 army personnel in 8th Brigade Infantry, Kelantan. A face validated self-administered Bahasa Malaysia questionnaire was used for data collection. Periodontal examination was done using Community Periodontal Index (CPI) and coded as ‘0’ for healthy; ‘1’ for bleeding observation; ‘2’ for detection of calculus; ‘3’ for probing of 4-5mm pocketing and ‘4’ for probing of 6mm or more pocketing. Results: All respondents (n=233) were male, the majority (92.7%) Malays, not married (60.5%) with the mean (SD) age of 25.8 (5.06) years. The prevalence of smoking among army personnel was 76.0% (95% CI: 70.4, 81.5). Almost all (97.4%) have some degree of periodontal disease. The non-smoker, ex-smoker and smoker groups were highest for having calculus with a percentage of 40.5%, 57.1%, and 57.1%, respectively. No significant association was found between smoking status (ever-smoker and non-smoker) and periodontal pocketing (CPI 0-2 and CPI 3-4) (p=0.960). However, the ever-smokers (93.2%) significantly higher percentage for the need of invasive treatment (CPI >2) compared to the non-smokers (76.2%) (p=0.002). Conclusion: The prevalence of smoking among army personnel in North-East Malaysia was high, with most of them have some degree of periodontal disease. Smoking cessation intervention should be strategized in the military community to reduce the burden of care for chronic diseases.

Nowadays, tobacco companies target to recruit new smokers among adolescents due to this age group was easy to be influenced by smoking behaviours. This narrative review aimed to explore the possible impact of smoking among adolescents. Knowing the negative impacts of smoking might result in avoiding continuing the habit or preventing from initiation of the habit. The literature search on PubMed, SCOPUS, and Epistemonikos database with related search terms of “adolescents”, “smoking” and “impact”. Only papers published within the year 2017 to 2021 and in the English language were included. However, articles without full text were excluded from this review. Fourteen articles were selected and divided impacts into three categories which are effect on oral health, effect on general health and other impacts. Possible impacts of smoking among adolescents were identified, and it could be beneficial in the development of customized smoking prevention or smoking cessation intervention for adolescents.

Introduction: School students are young adolescents who are in a period of acquiring good oral hygiene habits that are practised as they grow up. This study aimed to determine the association between oral health knowledge, attitude and practices (KAP) of the adolescents and their dental plaque maturity status. Methods: A cross-sectional study was conducted among 174 school students aged 13 to 14 years in Kota Bharu, Kelantan. The oral health knowledge, attitude and practices were assessed by self-administered questionnaires, while the dental plaque maturity status was assessed using GC Tri Plaque ID gel TM (TPID). The data were analysed using IBM SPSS version 24.0. Results: The mean (SD) for knowledge and attitude score of the students were 4.69 (1.44) and 3.63 (0.63), respectively. The mean (SD) dental plaque maturity score (DPMS) of the students was 1.02 (0.55). Students who had answered correctly on sugar and practised tooth brushing twice daily had significantly lower mean DPMS as compared to those who had answered incorrectly and practised tooth brushing less than twice daily (p<0.05). Conclusion: Adolescents participated in this study had moderate oral health knowledge and good oral health attitude. Correct knowledge regarding sugar and toothbrushing routines of at least twice a day significantly associated with the dental plaque maturity status.

Introduction: Autism spectrum disorder (ASD) is associated with behavioural problems which may affect children’s oral health statuses. Caregivers have crucial roles in caring for these children’s oral health. Thus, this study is aimed to evaluate the effectiveness of the Oral Health Care for Children with ASD (OHASD) Module in improving caregivers’ tooth-brushing difficulties in children ASD. Methods: Quasi-experimental study on caregivers of children with ASD aged 7 to 12 years who were registered at the Psychiatry Clinic Hospital Universiti Sains Malaysia (USM), Kelantan. The sociodemographic data obtained, and behavioural problems were assessed. Tooth-brushing difficulties were evaluated at pre- and six months post-intervention using OHASD Module. Data were analysed using IBM SPSS 26.0. Results: A total of 32 Malay children with ASD including their caregivers participated in this study. Caregivers were mostly mothers (78.1%) and children were mostly boys (84.4%), with mean age (SD) of 39.1 (4.19) and 8.8 (1.52) years respectively. Parent-reported questionnaire using the Modified Checklist for Autism in Toddlers (M-CHAT) showed 65.6% of children were highly sensitive to noises, 53.1% sometimes stared at nothing or wandered without purpose and 59.4% were unable to imitate caregivers’ faces. Significant differences between pre- and post-intervention for items; children who liked to close their mouths, turn their heads in different directions, did not understand the purpose of tooth-brushing (P<0.05). Conclusion: OHASD Module is useful in assisting caregivers in practising daily tooth-brushing of children with ASD.

Autism Spectrum Disorder (ASD) is a neurodevelopment disorder with an unidentified etiology and wide-ranging functional impact. This narrative review aimed to identify various behaviours and oral health problems among children with ASD, recognize the barriers towards oral health care, and identify the strategies for oral health care management. Online databases (Scopus, PubMed and Google Scholar) were used by using various search terms. All types of articles with different level of evidence were included. Articles which were not in English and were not available in full text were excluded. Various behavioural problems among ASD contributed to various oral healthcare challenges that lead to compromise oral health status. Caregivers and dental professionals have to identify these problems towards strategizing an effective oral health management for them. Therefore, this narrative review provide an insight towards controlling the oral health problems faced through preventative and practical approach for the chidlren with ASD.

Introduction: Oral health status among visually impaired (VI) children have shown to be poorer when compared with their normal peers. This preliminary study aimed to determine the oral health status of VI children and knowledge, attitudes and practices of their caregivers. Methods: A preliminary, cross sectional study were conducted on VI children and their caregivers attending Ophthalmology clinic Hospital USM. The assessment of oral hygiene was done using Sillness-Loe plaque index and dental caries using DMFT/dft index. Self-administered, validated questionnaires on knowledge, attitudes and practice towards a child’s oral health was distributed to the caregivers. Results: A total of 27 VI children along with their caregivers participated in this study. The mean age of VI children and their caregivers was 11.4(3.05) and 41.7(7.10) respectively. The children showed a fair oral hygiene status. The median(IQR) for caries experience for deciduous teeth (dft) and permanent teeth (DMFT) was 0.0(5.00) and 1.0(4.00) respectively. Caries prevalence among VI children was high at 85.2% (95% CI:70.86% - 99.51%). The caregivers showed a relatively good attitude and practice towards their child’s oral health with mean(SD) score of 23.2(2.95) out of 28 and 12.8(2.15) out of 19 respectively in comparison to low oral health knowledge of 5.5(1.50) out of 11. Conclusion: The oral hygiene status was fair with high prevalence of dental caries. Based on the score, although the caregivers showed to have minimal understanding on children’s oral health, their attitude and practice towards children’s oral health are relatively high.
