Pathosis or Additional Maxillary Neurovascular Channel? A Case Report

|April 23, 2018
Summary
Anatomic variations like the canalis sinuosus, a neurovascular channel, are common near maxillary incisors. Recognizing these channels is crucial for accurate dental radiographic interpretation and surgical planning.
Area of Science:
- Dentistry
- Oral and Maxillofacial Radiology
- Anatomy
Background:
- Dental radiographic interpretation requires understanding normal anatomy and common variations.
- Anatomic variations in the anterior maxilla can mimic pathology, potentially leading to misdiagnosis.
Observation:
- A case report details an incidental finding of a neurovascular channel near the maxillary right lateral incisor (tooth #7).
- Initial periapical radiography suggested inflammatory apical root resorption on tooth #7.
- Cone-beam computed tomography confirmed a neurovascular channel, likely the canalis sinuosus, superimposed over the tooth root.
Findings:
- The canalis sinuosus, an anatomic variant, is a neurovascular channel frequently found in the maxillary alveolus.
- This channel can be mistaken for periapical pathology on standard radiographs.
- The infraorbital canal is the origin of the canalis sinuosus.
Implications:
- Awareness of the canalis sinuosus is vital for clinicians interpreting dental radiographs in the anterior maxilla.
- Accurate identification of this neurovascular channel prevents misdiagnosis of periapical lesions.
- Understanding this anatomy aids in precise surgical planning for anterior maxillary procedures.

01:27Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
4.4K
α,β-Unsaturated carbonyl compounds with two electrophilic sites, the carbonyl carbon, and the β carbon, are susceptible to nucleophilic attack via two modes: conjugate or 1,4-addition and direct or 1,2-addition.
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are...

91.5K
The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.

3.7K
The attack of a nucleophile at the β carbon of an α,β-unsaturated carbonyl compound is called conjugate addition. Conjugate addition reactions of active methylene compounds, such as β-diketones, β-keto esters, β-keto nitriles, and α-nitro ketones, are called Michael addition reactions.

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

01:29Additives and Fillers in Concrete
360
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.
