まとめ
スリランカでは,特に第2の歯茎で,歯の根が合体することが一般的です. この根の解剖学を理解することは 歯内科治療の成功に不可欠です
科学分野:
- 歯科
- 口腔放射線科
- エンドドンティクス
背景:
- 歯茎の根の融合は 歯茎の間には歯周間隔がない
- 歯の根が溶けると 歯の内側には大きな問題が生じます
研究 の 目的:
- 根と根管の形状を評価する
- スリランカの集団における 融合した根の流行とパターンを調査する.
主な方法:
- 2017年から2019年のCBCTスキャンを分析した記述的研究です.
- 張社による分類 (2014) は,根融合型を特徴付けるために使用されました.
主要な成果:
- マキシラー第1歯茎の5. 1%,第2歯茎の43. 15%で溶融した根が発見されました.
- タイプ1の融合は第一歯歯 (42. 3%) で,タイプ2の融合は第二歯 (36. 9%) で最も一般的であった.
結論:
- この集団の根と管の形状は,以前の発見と一致しています.
- 融合した根は 根管システムを複雑にし 特殊な内歯科治療が必要になります
- より大きな集団でのさらなる研究が推奨されます.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
