METHODS: One hundred and twenty dentine discs were divided into three groups. The discs from each group were brushed with toothpaste containing bioactive glass, arginine and control toothpaste. Each group was then divided into four subgroups and exposed to acidic soft drink over four different time durations.
RESULTS: The scoring and the percentage of occluded dentinal tubules by Novamin-containing toothpaste was significantly better compared with arginine or the control toothpaste. Acidic soft drink challenge reduced the extent of dentinal tubules occlusion along with time. Dentinal tubules occluded by Novamin-containing toothpaste withstand the acidic challenge comparatively for a longer period.
CONCLUSIONS: The findings demonstrated that occlusion of dentinal tubules is more efficient by the bioactive glass-containing toothpaste and thus may contribute to its better resistance to acidic soft drink challenge.
METHODS: Relevant data from multiple data sources which include national oral health and health surveys, national census, extensive systematic literature reviews, as well as discussion with experts, were used to estimate the economic burden of non-surgical periodontal management in specialist clinics in Malaysia in 2020. This estimation was done from the oral healthcare provider's perspective in both public and private sectors using an irreducible Markov model of 3-month cycle length over a time horizon of one year.
RESULTS: In 2020, the national economic burden of non-surgical periodontal treatment during the first year of periodontal management in specialist clinics in Malaysia was MYR 696 million (USD 166 million), ranging from MYR 471 million (USD 112 million) to MYR 922 million (USD 220 million). Of these, a total of MYR 485 million (USD 115 million) and MYR 211 million (USD 50 million) were the direct oral healthcare cost in public and private dental clinics, respectively.
CONCLUSION: The findings of this study demonstrated substantial economic burden of non-surgical periodontal management in specialist clinics in Malaysia. Being a life-long disease, these findings highlight the importance of enforcing primary and secondary preventive measures. On the strength and reliability of this economic evidence, this study provides vital information to inform policy- and decision-making regarding the future direction of managing periodontitis in Malaysia.
METHODS: Dental therapists from two major public dental organisations in the East-Peninsular Malaysia (n = 26) were invited to participate in an audiotaped semi-structured interview using a pre-tested topic-guide informed by workforce policy and research literature. The qualitative data were transcribed and analysed using Framework Analysis.
RESULTS: The research conducted with dental therapists (n = 26) identified four motivation domains namely 'altruism', 'personal and academic inspiration', 'profession characteristics' and 'career advising and social influences' as key factors motivating their choice of a professional career as dental therapists, influenced by work-life balance and financial stability. They were also aware of the new dental act and its potential implications, particularly regarding their future career expectations. The majority felt the necessity 'to improve their skills and knowledge' within the first 5 years as part of their short-term career plans. A few participants expressed a desire to 'pursue a higher level of education' and 'wished to join the private sector' in the long-term. They perceived the possibility of 'working in the private sector' to increase their income and believed that they did not require any additional training for such a transition.
CONCLUSION: Malaysian dental therapists welcomed the changes in the new act, which allow them to work across sectors. Many perceived themselves as adequately motivated and equipped to transition to different work settings without requiring additional training.
