まとめ
歯科学生は、歯列弓パターン（口蓋皺襞鑑定）を用いた個人識別において高い精度を示しました。本研究は、専門家が利用できない場合に、法医学的識別において彼らが支援的な役割を果たす可能性を強調しています。
科学分野:
- 法歯学; 個人識別; 歯科解剖学
背景:
- 口蓋皺襞鑑定は、検証された法医学的識別方法です。一般歯科医の法医学的トレーニングの限定は、口蓋皺襞鑑定の信頼性に影響を与える可能性があります。このギャップを埋めるために、歯科学生の能力を評価することが重要です。
研究 の 目的:
- 法医学的識別における口蓋皺襞の認識と解釈に関する歯科学生の習熟度を評価すること。将来の歯科開業医が行う口蓋皺襞鑑定の精度と信頼性を決定すること。一般歯科専門家の間での法医学的識別における能力のギャップに対処すること。
主な方法:
- 最終学年の歯科学生54名が評価者として参加しました。40個の修正された上顎模型（歯なし）が照合演習に使用されました。検査再検査信頼性は、有病率調整バイアス調整カッパ（PABAK）を用いて評価されました。
主要な成果:
- 口蓋皺襞鑑定に基づく識別の平均精度は83.06%（±15.49%）でした。信頼性スコアは、実質的からほぼ完全（74.07%–96.30%）の範囲でした。平均照合時間は、鋳型あたり1.37分でした。
結論:
- 訓練を受けた歯科学生は、口蓋皺襞識別のにおいて有意な精度と信頼性を達成することができます。歯科学生は、特に法歯学者が不足している場合に、法医学的識別において貴重な資産として役立つことができます。精度と信頼性をさらに向上させるために、標準化された基準が推奨されます。

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...

01:15Teeth
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 and...

01:21Tooth Anatomy
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 grinding food.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
