Summary
Primary tooth root canal morphology is simple in anterior teeth but complex in molars. Deciduous molars frequently exhibit multiple canals, lateral canals, and anastomosis.
Area of Science:
- Dentistry
- Pediatric Dentistry
- Endodontics
Background:
- Understanding primary tooth root canal morphology is crucial for effective endodontic treatment in children.
- Variations in root canal anatomy can influence treatment outcomes and prognosis.
Purpose of the Study:
- To investigate the morphological regularity of root canals in primary teeth.
- To characterize the anatomy of deciduous root canals for improved clinical practice.
Main Methods:
- Transparent specimens of deciduous teeth were prepared.
- Root canal morphology was examined using a stereomicroscope.
Main Results:
- 92% of deciduous anterior teeth exhibited a single root canal.
- Deciduous molars showed greater complexity, with maxillary molars typically having 3 canals and mandibular molars having 4 canals.
- Lateral canals and anastomosis between root canals were common in deciduous molars.
Conclusions:
- Primary anterior teeth possess a relatively simple root canal system.
- Primary molar teeth present a more complex root canal morphology, including multiple canals and interconnections.

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...

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:26Bone 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...

01:27Cranial 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...
