Summary
This study found no significant difference in head and neck posture between bruxism patients and controls. However, bruxism patients showed a wider variation in the mental-sternal angle, with a higher prevalence of Angle
Area of Science:
- Dentistry
- Orthodontics
- Biomechanics
Background:
- Bruxism, characterized by teeth grinding or clenching, is a common parafunctional habit.
- Temporomandibular disorders (TMD) are associated with various signs and symptoms.
- Head and neck posture may influence or be influenced by TMD and malocclusion.
Purpose of the Study:
- To evaluate and compare head and neck posture in the rest position.
- To investigate potential relationships between posture, bruxism, and Angle's malocclusion classes.
Main Methods:
- Fifty-six volunteers (ages 18-27) were divided into a bruxism group (Group B) and a control group (Group C).
- Photographs of participants were analyzed using Alcimagem software to assess head and neck posture.
- Malocclusion was classified according to Angle's classification.
Main Results:
- No statistically significant differences in angular values of head and neck posture were found between the groups.
- Angle's Class I malocclusion was predominant in the control group (Group C).
- Angle's Classes II and III malocclusion were predominant in the bruxism group (Group B).
- While the mental-sternal angle showed no statistical significance between groups, Group B exhibited greater angular variation.
Conclusions:
- Head and neck posture in the rest position does not significantly differ between individuals with and without bruxism.
- Bruxism is associated with a higher prevalence of Angle's Classes II and III malocclusion.
- A greater variability in the mental-sternal angle may be associated with bruxism.

01:26Assessment of the Mouth
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.

01:21Tooth 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.

01:30Assessment of Airway, Skin Color, and Use of Accessory Muscles
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

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...

01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
