Asthma medicine can cause erosion in milk teeth


Asthma medicine can cause erosion in milk teeth

Erosion happens both enamel and dentin . Researchers´ concern is that other studies in the literature have warned that people with erosion in primary dentition have higher risk of developing erosion in the permanent dentition.

This is the Camila Scatena study´s main result, with the thesis " Effects of a potentially erosive antiasthmatic drug in the enamel and dentin of primary teeth : an in situ study " presented at the Ribeirão Preto Dental School ( FORP ) of USP.

According to literature data , the light shows dental erosion wear of the enamel and dentin can cause sensitivity . In later stages , there are changes in enamel morphology with dimples on the surface of the tooth. It can also result in loss of tooth height , and aesthetic commitment and , in severe cases, involvement of the pulp and the need for root canal treatment.

The researcher points out that this is another one of the reasons that health professionals are aware of the necessary care to people who use drugs routinely . There are various anti-asthmatic drugs , but most studies have shown that they have acidic pH and erosive potential . " The prolonged use of acid drugs in the oral cavity of children with chronic disorders cause concern, particularly by eating frequency and for night use , during which the protective effects of saliva are smaller."


According to dentists , this case, people who use acid medications for prolonged periods may increase calcium intake , eating cheese , yogurt and milk. Camila also suggests that specific use toothpaste to prevent erosion , mouthwash with fluoride to remineralize enamel or sodium bicarbonate to neutralize the acid , or even take the medicine with a syringe or straw so that there is no direct contact with the teeth , are also actions that minimize the impact of these drugs.

When she defended her master's degree in 2011 , also in FORP , Camila demonstrated in vitro erosive effect of Salbutamol sulphate , Syrup Vick and Ferrous Sulfate in primary teeth . " The question was whether in the mouth, in situ , with human saliva , which is naturally protective , and with fluoridated water and toothpaste , this result would repeat the enamel and dentin."

To evaluate the effect of Salbutamol in the oral environment , the researcher had 14 volunteers, with good general and oral health, without asthma , men and women , aged 18 and 35 , receiving apparatus similar to removable orthodontic , a sign on the palate, with fixed specimens consisting of pieces of enamel and dentin of primary teeth embedded in resin.

For five consecutive days, three times a day with the device out of the mouth , volunteers applied the anti-asthmatic drug in pieces of teeth and rinsed with running water . Then again put it in the mouth to have the effect of saliva. Only medicine was applied to the tooth pieces of one of the sides of the unit defined by lot . "In the enamel specimens exposed to the drug, was observed erosion has caused an increase in roughness , the wear profile and a reduction of the tooth surface hardness when compared to enamel that has not come into contact with the Salbutamol Sulphate "says Camila.

"In literature , the researchers are unanimous in stating that early diagnosis and intervention from the first years of life will help to prevent damage to permanent teeth ," she concludes.

The doctoral defense was at the end of October , in the Graduate Program in Pediatric Dentistry - FORP -USP , with the guidance of Professor Monica Campos Serra and collaboration of Professor Maria Cristina Borsatto . The researcher received a grant of Higher Education Personnel Foundation Coordination (Capes ) from the Ministry of Education, and the financial aid study by the National Council for Scientific and Technological Development ( CNPq).
