Summary
This study reports an extremely rare case of a maxillary canine tooth with three roots and three root canals. This anatomical variation is unprecedented in dental literature.
Area of Science:
- Dentistry
- Oral Anatomy
- Endodontics
Background:
- Maxillary canines typically present with a single root and a single root canal.
- Variations in root canal anatomy are uncommon but significant in endodontic treatment.
- Previous literature documents rare instances of two roots and two canals in maxillary canines.
Observation:
- A unique case of a permanent maxillary canine exhibiting three distinct roots was identified.
- Detailed examination revealed the presence of three separate root canals within these three roots.
- This presentation represents a significant deviation from typical canine tooth morphology.
Findings:
- The maxillary canine in this case demonstrated a trifurcated root system.
- Three independent root canals were confirmed, correlating with the three roots.
- This finding is the first documented instance of a three-rooted, three-canaled maxillary canine.
Implications:
- This case highlights the importance of thorough radiographic and clinical examination in endodontics.
- Understanding rare anatomical variations is crucial for successful root canal therapy.
- Such anomalies may necessitate modified endodontic approaches and treatment planning.

Histone Variants at the Centromere
5.0K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Anatomical Positions
19.6K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology
26.7K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements
15.4K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Primary and Secondary Growth in Roots and Shoots
60.3K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Cerebrum: Anatomical Overview II
4.5K
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...
