FAQ

Do scaling or air polishing work on discolouration caused by tetracycline?

No. Tetracycline discolouration is intrinsic: it became incorporated into the tooth structure during tooth development. It results from medication during crown formation between 6 months and 6 years of age, and its extent depends on the dose, duration of medication, mineralisation stage and degree of mineralisation activity [F1]. Cleaning procedures act on material attached to the tooth surface and cannot reach colour within the structure. This is not a difference in how well they work; the principle involves different layers.

テトラサイクリンによる変色に、スケーリングやエアポリッシングは有効ですか？ — 効果はありません。テトラサイクリンによる変色は内因性変色であり、歯の発育期に歯の構造へ取り込まれています。生後 6 か月から 6 歳までの歯冠形成期の投薬に由来し、その程度は用量、投与期間、石灰化段階、石灰化の活発さによって決まります [F1]。クリーニング処置が作用するのは歯面の付着物であり、構造内部の色には届きません。効果の良し悪しではなく、原理上、作用する層が異なります。
