まとめ
ピエゾシジョン後の口腔粘膜と歯肉は最小限の瘢痕で治癒し、ほとんどの切開は20週までに目に見える瘢痕がなかった。治癒は解剖学的な部位によって異なり、後方の領域では予後が悪かった。
科学分野:
- 口腔外科;創傷治癒研究;組織再生
背景:
- 口腔粘膜は、体の他の組織と比較して、瘢痕が最小限で優れた治癒を示す。;ケラチン化歯肉と非ケラチン化歯槽粘膜間の、特に口腔内組織の治癒ダイナミクスは、さらなる調査が必要である。;ピエゾシジョンは、口腔粘膜、骨膜、皮質骨への切開を伴う外科的技術である。
研究 の 目的:
- ケラチン化歯肉と非ケラチン化歯槽粘膜の異なる治癒特性を比較する。;これらの口腔組織におけるピエゾシジョン後の瘢痕形成と治癒ダイナミクスを分析する。;特定の時点での長期的な瘢痕の視認性と治癒結果を評価する。
主な方法:
- 26回の歯間ピエゾシジョンを受けた14人の患者を対象とした前向き研究。;処置後1、3、8、20週の標準化された写真を用いた粘膜瘢痕指数(MSI)による創傷評価。;治癒の進行と最終的な結果を評価するための瘢痕長とMSIスコアの分析。
主要な成果:
- 歯槽粘膜では最大3週間、歯肉では最大8週間で有意な瘢痕軽減が観察された。;後方の領域、特に下顎歯槽粘膜は、1週間でより高いMSIスコアを示した。;20週までに、歯肉切開の64.05%と歯槽粘膜切開の52.22%が無瘢痕であり、治癒は8週間後に安定した。
結論:
- ケラチン化歯肉と非ケラチン化歯槽粘膜の両方が、全層切開後に最小限または瘢痕なしで治癒する。;ケロイドや肥厚性瘢痕は観察されず、最終的な瘢痕の視認性は歯肉と歯槽粘膜の間で有意な差はなかった。;解剖学的な部位が治癒結果に影響を与え、後方の領域は予後が悪いことを示した。

Mucosal Barrier of the Stomach
2.3K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Oral Cavity
3.1K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Phases of Wound Repair
8.3K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.

Oral Hypoglycemic Agents: Glinides
664
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Psychosexual Stages of Personality: Oral
3.1K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors
1.2K
Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI) tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining.
