概括
在85.5%的第一个大牙中,存在第二个大牙通道 (MB2),但只有38.1%的牙可以进入顶部. 了解MB2解剖学可以提高这种具有挑战性的牙的内牙治疗成功率.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科解剖学 牙科解剖学
- 放射学 放射学是一门学科.
背景情况:
- 第一个大牙带来了重要的内牙挑战,主要是由于难以定位和治疗第二个牙道 (MB2).
- 上第一牙的内治疗失败率高,往往与未检测或未治疗的MB2通道有关.
研究的目的:
- 为了研究第一个尾大的第二个 mesiobuccal通道 (MB2) 的患病率和特征.
- 将发现与现有文献进行比较,以提高内牙治疗的效率.
- 分析不同年龄组的MB2通道检测率.
主要方法:

- 根据Vertucci的运河类型的分类,详细分析了76个上第一个牙.
主要成果:
- 在76个检查的上大中,65个 (85.5%) 发现了第二个口道 (MB2).
- 在检测到的MB2通道中,只有29个 (38.1%) 可以进入根顶.
- 在年轻的 (14-20岁,7.1%) 和年长的 (31-40岁,19.4%) 患者群体之间观察到未检测到的MB2通道的显著差异,可能是由于脉化.
结论:

Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...

Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Spongy Bone
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Tooth 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.
