Summary
An AI-based chatbot improved orthodontic patients' oral hygiene compliance. While the chatbot positively impacted oral hygiene, its effect on patient knowledge and satisfaction compared to traditional leaflets requires further investigation.
Area of Science:
- Dental Science
- Artificial Intelligence in Healthcare
- Orthodontics
Background:
- Effective patient education is crucial for successful orthodontic treatment outcomes.
- Traditional educational methods like leaflets may have limitations in engagement and personalized guidance.
- AI-powered chatbots offer a novel approach to deliver health information and support.
Purpose of the Study:
- To evaluate the impact of an AI-based chatbot on orthodontic patient education and oral hygiene.
- To compare the effectiveness of a chatbot intervention against standard educational leaflets in a randomized controlled trial.
Main Methods:
- A randomized controlled trial involving 100 patients allocated to either a chatbot group or a control group receiving leaflets.
- Intervention involved oral hygiene and orthodontic treatment guidance via chatbot or leaflets over 5 weeks.
- Clinical examinations (Modified Gingival Index, Plaque Index) and questionnaires assessed oral hygiene, knowledge, and compliance.
Main Results:
- Both groups showed a statistically significant increase in gingival and plaque indices from baseline to follow-up.
- The chatbot group demonstrated a statistically significant lower increase in the Modified Gingival Index compared to the control group.
- No significant differences were observed between the chatbot and control groups regarding questionnaire scores on knowledge, understanding, adherence, or satisfaction.
Conclusions:
- AI-based chatbots can positively influence patient compliance with oral hygiene practices during orthodontic treatment.
- The study did not establish whether the AI chatbot significantly enhanced patient knowledge, understanding, or satisfaction compared to information leaflets.
- Further research is warranted to optimize AI chatbot design for improved patient education and engagement in orthodontics.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

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...

In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

01:26Assessment of the Mouth
982
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.

01:27Fractures: Bone Repair
4.9K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

3.4K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.
