Summary
The most common root apex and apical foramen shape in human teeth is round. Most root apices and major foramina are centrally located, crucial for endodontic procedures.
Area of Science:
- Dental Anatomy
- Endodontics
- Morphology
Background:
- Understanding root apex and major foramen morphology is critical in dentistry.
- Variations in shape and position can impact endodontic treatment outcomes.
Purpose of the Study:
- To analyze the morphologic shape and position of the root apex and major foramen.
- To provide data on these anatomical features in maxillary and mandibular teeth.
Main Methods:
- Evaluated 845 human maxillary and mandibular teeth root specimens.
- Used microscopy (20x magnification) to assess root apex and major foramen shape and position.
- Categorized parameters including foramen shape (rounded, oval, etc.) and apex shape (rounded, flat, etc.).
Main Results:
- Round shape was the most frequent for both root apex (35.1%) and major foramen (52.9%).
- Oval shape was also common for the major foramen (25.2%).
- The center was the most prevalent location for both root apex (39.7%) and major foramen (58.4%).
Conclusions:
- Round morphology is predominant for both root apex and apical foramen.
- Central positioning is most common for both the root apex and major foramen.
- Findings offer valuable insights for endodontic diagnosis and treatment planning.

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.

01:15Teeth
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...

01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...
