Even though modern dentistry has come a long way since the days of dentists removing teeth without anaesthetic and gloves using panic-inducing, gigantic extraction ‘pliers’ that had never been sterilised on barbershop chairs, several myths circulating the field remain and even still strongly believed by certain parts of our community. Whether this stems from lack of education or mistrust from ‘Western’ medical practice, it is important to be knowledgeable and updated as delay or non-treatment of certain dental diseases that could have been prevented or treated early, could potentially be life-threatening for some of us, especially those with weakened immune system.

Myth 1: “Milk teeth are going to fall off eventually, so why treat them?”
False. Humans have two sets of dentition; primary or milk teeth, and secondary or permanent teeth. Milk teeth start to appear as early as 6 months of age and will naturally be exfoliated one by one to be replaced by a new set of permanent teeth from 6 years old. Although the milk teeth are temporary, they play important roles in jaw development and ensure your permanent teeth erupt in a correct position. Removing primary teeth before they’re supposed to naturally fall off could result in their permanent successor to appear in a haphazard way. Misaligned permanent teeth, other than being aesthetically unpleasant, could cause difficulty in cleaning them thoroughly. You know what happens if you don’t clean your teeth thoroughly.

Myth 2: “When we get old, we’ll lose all our teeth as a part of natural the ageing process.”
False. This is not necessarily true, as the longevity of your teeth has depends heavily on the good oral hygiene practice since a young age. Common dental diseases such as tooth cavities and gum diseases are preventable. Preventing tooth loss isn’t that difficult either. Aside from the usual twice daily tooth brushing with fluoridated toothpaste, flossing and limiting the frequency of sugar intake, seeing a dentist regularly is very helpful to get early lesion treated. Early treatment means better outlook, and better outlook means you’re more likely to retain the pearly whites until way past your retirement. Retaining your teeth also means the quality of life will be maintained; you will be able to enjoy an occasional steak or burger, at 16 or 61!

Myth 3: “If a tooth goes bad, just take it out. The filling is going to fail anyway.”
False. It is true that dental fillings can fail, but not all fillings are doomed to fail. If a tooth filling is done at an early stage of dental caries when the cavity is still small, there is a higher chance that the filling can survive for a long time; provided that you practice good oral hygiene habit and care for it like how you care for a natural tooth. This is why regular check-up is necessary; to detect early lesions of dental diseases and to get immediate intervention. Bear in mind that a tooth that has been filled can still get a new cavity if you neglect brushing and flossing. Removing the teeth doesn’t solve anything. You may get temporary relief from pain, but as time passes and several tooth removal later, you will realise that eating, speaking and socialising are not as enjoyable anymore. So you get a denture made to replace them, which doesn’t feel quite the same. You will get used to denture discomfort sooner or later, but it will never be able to replicate natural teeth.

Myth 4: “My teeth are yellow.”
True. Your teeth are yellow. And it is completely natural and healthy to have slightly yellow teeth. Enamel, the outermost layer of your teeth, is translucent. Dentine, the layer underneath the enamel, is yellow in colour. This gives the yellowish tint that is visible through the translucent enamel. If you have a fair complexion, your teeth can appear more yellow due to lack of contrast against your natural skin colour, and this is totally normal. As you age, your enamel will be gradually worn out from years of grinding and chewing, and become thinner, so that the dentine colour is even more visible. However, yellow teeth can also be caused by other reasons; smoking, pigmented beverages such as coffee and soft drinks, staining due to poor oral hygiene and tetracycline intake during tooth development stages. What is more important than having Hollywood-star-like white teeth is making sure that your teeth are clean and your breath doesn’t smell! However, if the yellowness bothers you, there are treatments that can be undertaken to lessen it, which can be discussed during your next dentist visit.

Myth 5: “Tooth extraction can cause eye damage.”
False again. Tooth extraction is completely safe for the eyes and doesn’t cause short or longsightedness or blindness. Although they may seem to be closely placed, the nerves supplying the teeth and the eyes are different. The nerves supplying the eyes go directly into the eyes as they emerge from the brain, while the nerves supplying the teeth go towards your facial structures. This is why you feel numbness in your cheek and lips after local anaesthetics injection. You may also feel numbness of the skin below your eyes if you get an injection for upper front tooth removal, but rest assured that the numbness only affects the skin. Your vision and eyeball movements remain unaffected, even if you get your ‘eye tooth’ removed.

Program Penjagaan Kesihatan Pergigian untuk Anak-anak Pelajar Pra-Sekolah.

INTRODUCTION

Pre-school children are one of the major target groups under the primary oral healthcare programme of the Ministry of Health. Oral healthcare for  pre-school children is given due priority as their oral health will determine the oral health status of future generations.

Several large-scale dental epidemiological surveys of 5 to 6-year-old children have been conducted in Malaysia. Findings show that caries prevalence in this group of children remains high although the rate is  declining. In the latest studies, caries prevalence of 87.1% was noted among 5-year-olds while in 6-year-olds, 80.6% had at least one or more  carious teeth in the deciduous dentition. For both groups, there was a  very high level of unmet treatment needs.

A structured pre-school programme has been in place in Malaysia since 1984. This programme focuses on preventive and promotive activities for pre-school children attending kindergartens (Taman Didikan Kanak-Kanak or tadika). A systematic referral system is also in place for the referral of children requiring curative care to the nearest government clinic.

In 1992, strategies and guidelines to implementation of all oral health programmes and activities were outlined in the document entitled “Strategi Ke Arah Perkhidmatan Pergigian Yang Cemerlang dan Bermutu” .

In view of the many changes that have taken place since then, there is a need to review the existing pre-school programme and to formallydocument the guidelines for the implementation of this programme. This would also facilitate planning of resources for the programme.

BACKGROUND

Since its launch in 1984, the pre-school programme has been mainly a preventive and promotive programme, with the objective of creating awareness and inculcating positive oral health habits and attitudes.

Through three visits to identified kindergartens or pre-schools, dental nurses and other auxiliaries carry out activities, which include dental health talks and tooth brushing drills. For a pleasant and fun introduction to the clinical aspects of oral healthcare, role-play is also carried out on the third visit. Through the years, implementation of the pre-school programme has seen some modifications. A kindergarten was previously considered “covered” when three visits were made. However, due to resource constraints, this was reduced to two visits in certain locales. This was supported by a local study, which found no difference in effectiveness between a two–visit and a three-visit programme.

In recent years, some districts took it a step further by undertaking the task
of treating pre-school children as an outreach programme. Treatment has been made more acceptable to these younger children with the development of the minimally invasive technique of Atraumatic Restorative
Treatment (commonly referred to as ART). This pre-school outreach programme was further facilitated with the establishment of pre-school  teams under the 7th Malaysia Plan (1996 - 2000).

In August 2000, the Oral Health Division, Ministry of Health, organised a seminar on “Atraumatic Restorative Treatment in The Management of Dental Caries” in Kota Bharu, Kelantan. Participants, comprising dental officers and nurses, were trained to undertake ART in concurrent workshop sessions in local kindergartens. The guidelines to implementation of the ART programmewere adhered to. Similar workshops were organised at state level.

Through the pre-school programme, nearly 100% of government-aided kindergartens and pre -schools registered with the Ministry of Education are “covered” each year.
