Effect of Periapical Lesion on Periodontal Lesion in Rats.

Nihon Shishubyo Gakkai Kaishi (Journal of the Japanese Society of Periodontology), 1993
今回の実験では, ラットの根尖病変が歯周病変に及ぼす影響を組織学的および組織形態計測学的に検索した。ラットを処置方法の違いによって, A, B, C群およびa, b, c群に分けた。全ての動物では, 上顎臼歯の歯間部にナイロン糸を挿入した。A, B, C群では, ナイロン糸挿入後から, それぞれ4, 8, 12週でその歯周組織を観察した。さらに, a群では, ナイロン糸挿入と同時に臼歯を露髄し, 処置後4週で観察した。また, b, c群では, ナイロン糸挿入して4, 8週後に臼歯を露髄し, 露髄後4週で観察した。組織学的には, A, B, C群では, 歯間部の歯周組織には炎症病変が成立した。しかし, その歯周病変は根尖部および根分岐部の歯周組織に波及することはなかった。a群では ...

Impact of abrasive versus non‐abrasive cleaning on peri‐implantitis titanium release: A randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background Surface decontamination is integral to peri‐implantitis treatment. However, abrasive mechanical methods can cause implant surface degradation with possible adverse biological effects. No human studies have examined whether these treatments cause titanium release or impair regenerative outcomes.
