Glerungseyðing og gosdrykkir

Abstract

Objective: Acidic soft drinks are well-known causes of dental erosion. This study aimed to determine differences in the in-vitro erosive effect of a selection of drinks on the Icelandic market. Materials and methods: 20 different brands of soft drinks were investigated. 13 freshly extracted human teeth were sawn in 2 pieces. The erosive effect of drinks was determined as the percentage weight loss of tooth pieces after immersion in the drinks. Drink samples were renewed daily, and the weight of the teeth was recorded. Results: Drinks containing citric acid had an average of 12.5% greater erosive effect than drinks containing phosphoric acid. Sugared soft drinks and energy drinks had a considerably higher erosive potential than water-based drinks. Flavored water containing citric acid showed similar erosive potential to cola drinks that contain phosphoric acid. Flavored and non-flavored water not containing acidic additives showed similar erosive effect to the control drinks water and milk. Overall, energy and sports drinks showed the most erosive effect, with sugary citric acid drinks close behind. Discussion: Advice to patients on consumption of soft drinks should recognize their erosive effects especially regarding flavored waters. Citric acid in drinks appears to be more erosive than phosphoric acid, particularly where sugar is also an ingredient, perhaps balancing sweetness and acidity.

Þekkt er að gosdrykkir geta valdið glerungseyðingu. Með rannsókninni var ætlað að mæla glerungseyðandi mátt mismunandi gosdrykkja á tilraunastofu. Efniviður / Aðferð: 13 nýúrdregnar tennur voru sagaðar í tvennt og lagðar í 20 mismunandi gosdrykkjaböð og glerungseyðingarmáttur var metin út frá prósentu-þyngdartapi tannhlutanna. Daglega voru drykkirnir endurnýjaðir og tennurnar vigtaðar. Niðurstöður: Drykkir sem innihalda sítrónusýru hafa meiri glerungseyðandi mátt en þeir sem innihalda fosfórsýru. Sykraðir gosdrykkir og orkudrykkir eru meira glerungseyðandi en vatnsdrykkir. Bragðbætt vatn með sítrónusýru er jafn glerungseyðandi og þeir drykkir sem innihalda fosfórsýru. Bæði sýrulaust bragðbætt og óbragðbætt vatn var ekki glerungseyðandi líkt og samanburðardrykkirnir vatn og mjólk. Orku og íþróttadrykkir voru mest glerungseyðandi en sykur- og sítrónusýrudrykkir lágu mjög nálægt. Ályktun: Í leiðbeiningum ætti að leggja áherslu á mismunandi glerungseyðingamátt vatns/íþrótta- og orkudrykkja. Drykkir sem innihalda sítrónusýru eru meira glerungseyðandi en drykkir með fosfórsýru.
