Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Cardiopulmonary Resuscitation II: ACLS Airway Management

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
Distance Corrections01:15

Distance Corrections

To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Area of Science:

  • Orthodontics
  • Craniofacial Development
  • Dental Malocclusion

Background:

  • Angle's Class II, division 1 malocclusion is a common dental issue.
  • Effective treatment strategies are crucial for optimal outcomes.
  • The MARA appliance is a device used in orthodontic treatment.

Purpose of the Study:

  • To evaluate the effectiveness of the MARA appliance.
  • To assess its impact on Angle's Class II, division 1 malocclusion.
  • To analyze skeletal and dental changes induced by the MARA appliance.

Main Methods:

  • A comparative study involving 44 young patients.
  • MARA Group (treated) vs. Control Group (untreated).
  • Lateral cephalograms analyzed using cephalometric variables and Student's t test.

Main Results:

  • MARA appliance restricted maxillary growth and improved maxillomandibular relationship.
  • Significant reduction in overbite and overjet observed.
  • Dental changes included incisor retrusion/protrusion and molar distalization/mesialization.

Conclusions:

  • The MARA appliance is effective for correcting Angle's Class II, division 1 malocclusion.
  • It induces significant skeletal and dental modifications.
  • The appliance demonstrates efficacy in improving patient occlusion.
