Summary
A systematic review found that atypical swallowing is linked to malocclusions, particularly posterior crossbite in children aged 3-11. Further research is needed due to low certainty of evidence.
Area of Science:
- Dentistry and Oral Health
- Pediatric Health
- Speech-Language Pathology
Background:
- Atypical swallowing patterns can influence oral structures.
- Malocclusions, or misaligned teeth, are common in pediatric populations.
- Understanding the relationship between swallowing and dental alignment is crucial for early intervention.
Approach:
- Systematic review of cross-sectional studies up to February 2021.
- Searched EMBASE, LILACS, LIVIVO, PubMed/Medline, Scopus, Web of Science, and gray literature.
- Included studies on children, adolescents, and adults with and without atypical swallowing and malocclusion.
Key Points:
- Four studies were included after reviewing 4,750 articles.
- Atypical swallowing was associated with distal occlusion, extreme maxillary overhang, and open bite.
- Posterior crossbite was the most frequently associated malocclusion with atypical swallowing.
Conclusions:
- Atypical swallowing is associated with malocclusions, especially posterior crossbite in young children (3-11 years).
- The certainty of evidence is very low, and included studies had a moderate to high risk of bias.
- This highlights a potential link requiring further investigation in pediatric populations.

01:26Assessment of the Mouth
300
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:26Esophageal Strictures-II: Clinical Features and Management
125
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

01:25Deglutition
2.2K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

01:24Upper GI Series: Barium Swallow
636
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

01:30Esophageal Strictures-I: Introduction
202
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

01:12The Hyoid Bone
2.3K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
