Smokers have small root coverage which is associated with bad vascularity of periodontal tissues. This study evaluated a technique that can increase the blood supply to the periodontal tissues compared with a traditional technique. Twenty heavy smokers (10 males and 10 females) with two bilateral Miller class I gingival recessions received coronally positioned flaps in one side (Control group)a...

Confidence intervals are commonly used to describe parameter uncertainty. In nonstandard problems, however, their frequentist coverage property does not guarantee that they do so in a reasonable fashion. For instance, confidence intervals may be empty or extremely short with positive probability, even if they are based on inverting powerful tests. We apply a betting framework and a notion of be...

OBJECTIVES The aim of this study was to evaluate the influence of the crown shape on the outcomes of root coverage procedures. MATERIAL AND METHODS Eighty patients with Miller class I gingival recessions in maxillary canines or premolars were selected. The recession areas were treated using the subepithelial connective tissue grafting. The following clinical parameters were analyzed: crown le...

Background The aim of this systematic review was to evaluate whether patients with gingival recession would benefit from an acellular dermal matrix graft (ADMG) in ways that are comparable to the gold standard of the subepithelial connective tissue graft (SCTG). Materials and Methods A systematic review and meta-analysis comparing ADMG to SCTG for the treatment of Miller Class I and II recess...

スギ挿し木コンテナ苗の出荷に適した根鉢形成状態を判断する指標として，根系による培地の表面被覆度合い（以下，表面被覆率）の有効性を検討することを目的として，コンテナ苗を用いた落下試験を行い，根量および表面被覆率と落下の衝撃で脱落する培地の割合との関係を調査した。その結果，脱落培地量を目的変数とした一般化線形モデルの結果では，表面被覆率を説明変数に採用したモデルが最適モデルとして選択された。また，コンテナ苗の根鉢の表面被覆率が高くなるのに伴って脱落培地率が指数関数的に減少した。以上の結果から，表面被覆率が挿し木コンテナ苗の根鉢強度の指標として利用可能であること，ならびに本研究で採用した培地の脱落量の許容基準（6％）に照らした場合，27％程度以上の表面被覆率がなければ最低限必要な根鉢強度が得られないことが示された。

BACKGROUND In the presence of a thin and narrow zone of gingival tissue root recessions caused by trauma or inflammatory reactions seem to be a common feature of the buccal tissue morphology. The surgical coverage is mainly indicated for aesthetic reasons and may be accomplished with pedicled flaps in conjunction with or without the use of connective tissue grafts. AIM The purpose of the pres...

Based on unmixing model and using the Thematic Mapper (TM) image as well as obtaining end-members by ground spectral measurements, quantitative retrieval of information on sparse vegetation coverage in oasis-desert transitional area in Minqin, Gansu was done. The results showed that a wide band of TM images can be used in extracting sparse vegetation coverage of arid regions. Three components w...

Soft tissue recession leads to root exposure which results in root caries, unaesthetic appearance and dentinal hypersensitivity. Aesthetic treatment such as root coverage procedures have become integral part of periodontal treatment. Platelet Rich Fibrin (PRF) is a new promising autogenous, less invasive and effective mode of treating gingival recession. This case report highlights the use of P...

AIMS AND OBJECTIVES Obtaining root coverage has become an important part of periodontal therapy. The aims of this studyare to evaluate the clinical efficacy of acellular dermal matrix graft in the coverage of denuded roots and also to examine the change in the width of keratinized gingiva. MATERIALS AND METHODS A total of 20 sites with more than or equal to 2 mm of recession depth were taken ...
