Fluorosis is important to measure because it is a condition that can be used as biomarker for the level
of fluoride exposure during enamel formation. Increased and decreased in fluorosis prevalence may also reflect
to the different ways of measuring the disease. The choice of measuring fluorosis is depends on the objective of
the assessment such as assessing public health significant of fluorosis in the population or assessing the detailed
of biological effects of fluoride. These differences in requirement have led to the adoption of many indices and
assessment methods of enamel fluorosis, which subsequently led to evaluation of examiner agreement between
them. Several indices were developed to measure dental fluorosis in the 20th century. These include fluorosis
specific indices such as Dean’s Index; the Thylstrup and Fejerskov Index; the Total Tooth Surface Index; and the
Fluorosis Risk Index. Non-specific descriptive indices such as the Developmental Defects of Enamel index have
also been used to record fluorosis. Fluorosis has most commonly been recorded using clinical examinations and
photographs. Recent developments have seen the use of a Visual Analog Scale and automated grading systems
such as Quantitative Light Fluorescence emerge as possible enhancements to fluorosis scoring. This article aims
to review existing indices and new methods in measuring dental fluorosis, together with examiner reliability
across different methods and indices.
Dental quackery has been a problem for decades and is becoming a major concern in many countries, including Malaysia. Recent development of a new service offered by quacks in Malaysia is “fake braces”, which alarmed dental professionals. The fake braces appear similar to the professionally fitted orthodontic appliances comprising of archwires that are secured on brackets by coloured ligatures except they are fitted by unqualified individuals who have no formal clinical training. In addition, the orthodontic materials and dental equipment used for this illegal service were substandard and unregulated. Therefore, such fitted appliances are harmful to the teeth and oral health. Efforts to record the extent of fake braces practice and its oral health consequences have been challenging as they are marketed through the social media, and the victims were either reluctant to come forward or did not know the appropriate channel to file a complaint to the health authority. This is an expert opinion paperwith theaimsto highlight typical presentation of fake braces, modus operandi of fake braces providers, the harmful effects of fake braces on the patient’s oral health, the role of social media advertising in promoting fake braces, and the impacts to the illegal providers.
Objective: This study aimed to assess self-perceived aesthetics and orthodontic need, information-seeking behaviours and knowledge on orthodontic treatment among young adults in Malaysia.
Methods: A cross-sectional study was conducted among 933 polytechnic students in Malaysia using a selfadministered questionnaire. The Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used to assess self-perceived orthodontic need. Respondents were also asked about their intention to seek orthodontic treatment. Those showing intention were further asked about their reason(s) for seeking treatment, their information-seeking behaviours, and knowledge on orthodontic treatment. Data was analysed using SPSS.
Results: The overall response rate was 93.2% with the mean age of 20.43 (SD±1.07). Although most of the respondents rated themselves under the no treatment need category of the AC-IOTN scale, 61.9% reported intention to seek orthodontic treatment. The main reason for seeking treatment was to improve dental function (45.3%) and aesthetics (40.1%). Most claimed to look for information prior to orthodontic treatment, either using online or offline platforms. Many relied on friends (83.3%) as a source of information and more than half used online sources including social media and websites. A minority demonstrated lack of knowledge in terms of appropriate places to receive treatment (2.2%) and qualification of orthodontic practitioners (37.7%).
Conclusions: The majority of young Malaysian adults have high intention to seek orthodontic treatment regardless of their perceived need. A minority had lack of knowledge about qualified orthodontic providers and places to receive treatment. Majority reported positive attitudes towards information-seeking behaviour prior to seeking orthodontic treatment.
Information regarding water fluoridation (WF) in Malaysia has been substantially documented, but is scattered in various government publications and may be lost to the stakeholders. This paper is a review of water fluoridation in Malaysia and its effect on oral health: a history of WF in Malaysia, the current policy, the evidence of its effectiveness, the challenges and the future directions. A search for relevant physical and electronic documents of WF in Malaysia resulted in the identification of 70 documents for review. WF was gazetted as national policy with an optimal fluoride level of 0.7 parts-per-million (ppm) in 1972, with a reduction of the level to 0.5 ppm in 2005. Evidence showed that WF effectively reduced population dental caries while fluorosis was not a prevalent public health concern. Strong collaboration between stakeholders and the extensive network of piped water supplies resulted in 80% of the population receiving WF in 2013. However, the coverage was reduced to 74.1% in 2018, largely due to the cessation of WF in Pahang. The key challenges in WF included a lack of funding, weak legislation, use of reverse osmosis water filtration system, difficulty to maintaining an optimal level of fluoride in the water, and lack of local data on the impact of WF cessation on oral health, and its cost-effectiveness. This review will provide dental health professionals with scientific evidence on WF and oral health in Malaysia and assist them in answering relevant questions about WF raised by the public.
