Dental Procedures & Techniques Flashcards

What is the purpose of a dental filling?

Answer: To fill a cavity and restore tooth function

The primary purpose of a dental filling is to repair a tooth that has been damaged by decay, restoring its structural integrity and functionality. After the decayed portion of the tooth is removed, the cavity is meticulously cleaned and then filled with a restorative material like composite resin or amalgam. This process prevents further decay, alleviates sensitivity, and allows the tooth to function normally during chewing.

What type of dental procedure is typically used to treat a root canal?

Answer: To clean and disinfect the root canal

A root canal procedure, also known as endodontic treatment, is typically performed when the pulp inside a tooth becomes infected or inflamed due to deep decay, cracks, or trauma. The procedure involves carefully removing the infected or damaged pulp, thoroughly cleaning and disinfecting the intricate root canal system. Finally, the canals are filled and sealed to prevent future infection, thereby saving the natural tooth from extraction.

What is the role of dental sealants?

Answer: To protect molars from cavities

Dental sealants are thin, protective coatings applied to the chewing surfaces of molars and premolars, which often have deep grooves and pits. These anatomical features can easily trap food particles and bacteria, making them highly susceptible to decay. Sealants act as a physical barrier, preventing plaque and acids from accumulating in these vulnerable areas, thereby significantly reducing the risk of cavities, especially in children and adolescents.

What is the first step in a dental cleaning procedure?

Answer: Scaling to remove plaque and tartar

The first and most crucial step in a professional dental cleaning procedure is scaling, which involves the meticulous removal of plaque and hardened tartar (calculus) from the tooth surfaces. These deposits accumulate both above and below the gumline and cannot be removed by regular brushing alone. Scaling is essential for preventing gum disease, reducing inflammation, and preparing the teeth for subsequent polishing and fluoride application.

What is a common material used for dental crowns?

Answer: Porcelain, metal, or porcelain-metal combination

Dental crowns are custom-made caps that cover a damaged or weakened tooth, restoring its shape, size, strength, and appearance. Common materials used for crowns include porcelain, which offers excellent aesthetics, various metals (like gold alloys) for superior strength and durability, or a combination of porcelain fused to metal (PFM) to blend both aesthetic appeal and resilience. The choice of material depends on the tooth's location, the patient's bite, and their aesthetic preferences.

What is the role of orthodontic brackets in braces?

Answer: To connect the braces to the archwire

Orthodontic brackets are small, square attachments that are bonded directly to the surface of each tooth during orthodontic treatment with braces. Their primary role is to serve as anchors, securely holding the archwire in place. The archwire, which passes through the slots in the brackets, applies gentle, continuous pressure to gradually guide and move the teeth into their desired, aligned positions over time.

What is the purpose of fluoride treatments in dentistry?

Answer: To strengthen enamel and prevent decay

Fluoride treatments in dentistry are primarily used to strengthen tooth enamel, making it more resistant to acid attacks from bacteria and sugars, which are the main cause of cavities. Fluoride helps in the remineralization process, repairing early signs of tooth decay and preventing its progression. This treatment is a vital preventive measure, especially for individuals at high risk of developing cavities.

What is the role of dental implants?

Answer: To replace missing teeth with a post and crown

Dental implants are a highly effective and durable solution for replacing missing teeth. They consist of a titanium post surgically placed into the jawbone, which acts as an artificial tooth root. Once the implant integrates with the bone, a custom-made crown, bridge, or denture is securely attached to it, restoring both the aesthetic appearance and full chewing function of the missing tooth or teeth.

What is the role of dental x-rays?

Answer: To detect hidden issues such as cavities and bone loss

Dental X-rays, or radiographs, are indispensable diagnostic tools that allow dentists to visualize structures and conditions not apparent during a routine clinical examination. They are crucial for detecting hidden issues such as interproximal cavities between teeth, bone loss indicative of periodontal disease, impacted teeth, cysts, or other abnormalities within the jawbone. This detailed internal view is vital for accurate diagnosis and comprehensive treatment planning.
