Dental Decay report from Pakistan


 

As part of visiting Pakistan to view sponsored free cataract and cleft palate operations, I had the opportunity to visit , examine and assess the oral health of around 12000 children in 18 schools in parts of northern Pakistan around the city of Gurjurat.

The schools varied from free Government schools, part private schools and totally private schools both in the city of Gurjurat and in the surrounding very rural areas in that district.

The pattern of my visit was an arranged address to the whole school with a simple short message and demonstration on tooth brushing and diet advice, followed by examination of a number of children either directly in front of the assembly using the portable dental chair as designed by Dentaid with attached led examination light or in a previously set up side room.

Those examined had a dmf( decayed missing filled)  count and those with more serious evidence of decay counselled further. Numbers examined in each school varied from 30 to 90 children. 81% of the children examined had poor oral hygiene and the need for improved tooth brushing technique was repeated. 39% of children examined whose ages arranged from 5 to 9 years old have carious affected teeth. ( dmf counts from 3 to  8)   In about 15 % of cases there was evidence of severe carious lesions (with dmf counts from 9 to 20). I also examined a number of adults and teachers who all showed untreated caries, many with totally collapsed first permanent molars for which extraction is the only treatment option. Because the decay was in most cases involving the whole of the crowns of the teeth, there was little food trapping and any infection present was able to drain through the open cavities. Patients did complain that they did have pain sometimes on eating and in a few cases evidence of a sinus discharge from the apex of the decayed tooth was present.

A determined effort was made in all 18 schools to engage all the teachers into the realisation that the high level of caries in the primary teeth of most of the small children was being caused mainly by a bad pattern of frequent sugar consumption both in drinks and food. The devastation of the primary dentition in a great many children reminded me of the ‘baby feeder’ syndrome and gross caries I used to see in small children shortly after qualifying and practicing in Walsall in 1970. The routine serial extraction of first molars was commonplace. A barrier to seeking dental care is the cost which would be beyond the resources of a large proportion of the population. They is the risk that such patients will seek treatment from totally unqualified individuals for in reality not much less cost in money terms but an enormous cost for the patient in health terms with the risk of cross infection from inadequately autoclaved instruments, so transmitting hepatitis and other viral infections.

A few decades on, with improved diet patterns, better tooth brushing and of course both fluoride in the water supply and toothpaste has resulted in the midlands of a total transformation in the caries rate amongst children.

However as has been highlighted by WHO and others, there is a large increase in caries amongst young children in developing poorer communities now getting virtually unrestricted access to sweetened foods and drinks .

There was strong evidence that the exposure of the primary dentition to a corrosive mix of sugar and low ph drinks was present during the eruption of this dentition resulting in the  loss of enamel over the whole surface of the exposed crowns and giving the dreadful blackened appearance of the remains of the primary dentition.

The aim of this exercise in entering primary schools, giving direct simple advice on the importance of tooth cleaning and a reasonable pattern of sugar consumption will be continued by their teachers on a daily or at least on a weekly basis and will begin to start a change in behaviour of the children and so their parents. This must be sustained by future visits with a reinforcement of the message.. perhaps by volunteer dental students and further dentists who can speak Urdu and so have a better chance of training more teachers and other key personnel to repeat the message. As with all health advice this needs to be simple, clear ,realistic and repeated frequently and the dental message tied in with linked health advice on healthy eating and lifestyles. In dental care ,there is also of course a place for simple interventions, fissure sealing first molars for those children at most risk, glass ionemer restorations on early food trapping cavities; active supervised fluoride toothpaste application of very small amounts ( after check on levels of any local fluoride content)

I was very well received by the many schools I visited and impressed by the obvious concern expressed by their teachers who did not often realise the extent of the caries problem. I also thank a local dentist who accompanied me to most of the schools and was able to translate our oral health care message.  The easily portable dental chair makes it easy to check comfortably many children and lends a more professional approach to oral health assessments. There is a real opportunity to follow up this initial brief visit with a longer term sustainable oral health campaign linked also into treatment and care for adult patients with their high incidence of periodontal problems and awareness of danger of practices that will increase the risk of developing oral cancer.
