Periodontics | Local Factors | INBDE, ADAT
TLDRIn this informative video, Ryan dives into the local factors that contribute to the development of periodontal disease, focusing on the accumulation and retention of plaque and microorganisms. He explains that calculus, a mineralized form of dental plaque, isn't harmful by itself but becomes problematic when covered with bacterial plaque. Calculus can be found both above and below the gum line and can be detected visually or radiographically. Ryan also discusses other factors such as materia alba, extrinsic stains, malocclusion, prominent roots, missing teeth, faulty restorations, dental appliances, and self-inflicted injuries. Each of these can indirectly affect periodontal health by creating an environment conducive to plaque buildup or by causing damage to the gums. The video serves as a comprehensive guide for understanding the multifaceted nature of periodontal disease and the importance of good oral hygiene and dental care.
Takeaways
- π¦· **Calculus Formation**: Calculus is mineralized dental plaque that forms on teeth and can contribute to periodontal disease due to the bacterial plaque covering its surface.
- π **Types of Calculus**: There are two types of calculus - supragingival (white or yellowish) and subgingival (dark brown or black), both of which can harbor harmful bacteria.
- π **Detection Methods**: Calculus can be detected visually, with an air spray for smaller deposits, or through tactile sensation using an explorer, and radiographically for larger accumulations.
- π **Materia Alba**: Materia Alba is a soft, white substance made of bacterial proteins, shed epithelial cells, and food debris, which is an early form of plaque.
- π¨ **Extrinsic Stains**: Stains on teeth are primarily aesthetic concerns but can indicate underlying issues like poor oral hygiene or consumption of certain substances like dark beverages or tobacco.
- π« **Chlorhexidine & Stannous Fluoride**: Use of these dental products can lead to yellow-brown staining and patients should be informed of this potential side effect.
- 𦴠**Malocclusion Issues**: Problems like crowded teeth or prominent roots can indirectly contribute to periodontal disease by making it difficult to maintain proper oral hygiene.
- βοΈ **Faulty Restorations**: Overcontoured dental restorations can create areas that are difficult to clean, leading to plaque accumulation and potential periodontal issues.
- π **Radiographic Analysis**: X-rays can reveal calculus deposits that are not visible to the naked eye, especially in areas that are not easily accessible for cleaning.
- π **Oral Appliances**: Removable partial dentures and braces can increase plaque retention and put additional stress on the periodontium, requiring careful management.
- βοΈ **Self-Inlicted Injury**: Aggressive brushing, misuse of toothpicks, or other harmful habits can damage gingival tissues and increase the risk of periodontal disease.
Q & A
What is calculus in the context of dentistry?
-Calculus is mineralized dental plaque, which is the precipitation of mineral salts into the plaque. It usually occurs within one to fourteen days and is often covered with a layer of bacterial plaque, which serves as a primary irritant to gingival tissues.
How does calculus contribute to periodontal disease?
-While calculus itself is not harmful, its outer surface is covered with a layer of plaque bacteria, which can contribute to periodontal disease. Calculus does not serve as a mechanical irritant by itself but provides a surface for plaque bacteria to accumulate.
What are the two forms of calculus and where are they typically found?
-There are two forms of calculus: supragingival and subgingival. Supragingival calculus is whitish-yellowish, mineralized by saliva, and often found near salivary duct openings, such as on the lingual surfaces of the mandibular anterior teeth. Subgingival calculus is darker, either brownish or blackish, mineralized by gingival crevicular fluid.
How can calculus be detected in the mouth?
-Calculus can be detected visually, especially when significantly accumulated. For smaller and more nuanced accumulations, an air spray or tactile sensation with an explorer can help in detection. Proximal calculus on the mesial and distal surfaces of teeth can often be detected radiographically through X-rays.
What is materia alba and how is it related to plaque?
-Materia alba is a soft, white, organized accumulation of bacterial proteins, shed epithelial cells, and occasional food debris. It is easily displaced with water spray and is considered a precursor to plaque, representing the debris of food after a meal.
Why are extrinsic stains important to dentists?
-Extrinsic stains are primarily an aesthetic concern and do not contribute to gingival inflammation. However, they can point to underlying factors that a patient may be experiencing, such as poor oral hygiene or consumption of certain beverages and substances.
What are some common causes of different types of extrinsic stains on teeth?
-Orange stains are usually due to poor oral hygiene, brown stains are often from drinking dark-colored beverages like coffee, tea, or coca-cola, dark brown or black stains are due to tobacco use, yellow-brown stains are from the use of chlorhexidine and stannous fluoride, and green and yellow stains can be from chromogenic bacteria or poor oral hygiene.
How can malocclusion contribute to periodontal disease?
-Malocclusion, such as crowding or overlapping of teeth, can contribute to plaque accumulation and indirectly to periodontal disease. It creates plaque retentive areas that are hard to clean, and can affect a patient's motivation to maintain good oral hygiene.
What is the impact of missing teeth on periodontal health?
-Missing teeth can lead to food impaction and plaque retention. The neighboring teeth may tip into the empty space, and opposing teeth may hyper-erupt due to the lack of opposition, leading to problems with the patient's bite.
How can faulty restorations contribute to periodontal disease?
-Faulty restorations, such as overhanging margins, open margins, rough surfaces, and open contacts, provide perfect environments for plaque retention. Over contoured restorations are particularly harmful as they form plaque retentive areas that are difficult to clean.
What are some dental appliances that can contribute to periodontal disease?
-Removable partial dentures can result in increased mobility of the abutment teeth and increased plaque accumulation. Braces can also increase plaque retention and create excessive forces on the periodontium, making it important to establish periodontal health before orthodontic therapy.
What is the impact of aggressive horizontal brushing on periodontal health?
-Aggressive horizontal brushing can cause tooth abrasion and gingival recession, which are considered local factors that can increase the risk for periodontal disease, especially when combined with poor oral hygiene practices.
Outlines
π¦· Calculus and Plaque in Periodontal Disease
The first paragraph introduces the concept of calculus, which is mineralized dental plaque, and its role in periodontal disease. Although calculus itself is not harmful, it often has a layer of bacterial plaque that can lead to periodontal issues. The video explains the difference between supragingival (white/yellowish) and subgingival (dark brown/blackish) calculus, their formation, and how they can be detected visually or radiographically. It also discusses materia alba, a soft white substance that is a precursor to plaque, and extrinsic stains, which are primarily aesthetic but can indicate underlying oral health issues.
π Factors Affecting Oral Hygiene and Periodontal Health
This paragraph delves into various factors that can affect oral hygiene and contribute to periodontal disease. It covers the impact of poor oral hygiene on staining, the effects of using chlorhexidine and stannous fluoride, and how dietary habits like consuming dark-colored beverages or tobacco can lead to staining. The paragraph also touches on how malocclusion, prominent roots, missing teeth, and faulty restorations can indirectly contribute to plaque accumulation and periodontal disease. It emphasizes the importance of proper dental restorations to prevent plaque retention and the need for good periodontal health before any orthodontic treatment.
β οΈ Local Factors Causing Periodontal Disease
The third paragraph discusses local factors that can lead to periodontal disease, including removable dental appliances like partial dentures and braces, which can increase plaque accumulation and put stress on the periodontium. It also mentions how oral jewelry and aggressive brushing techniques can cause damage to teeth and gingival tissues. The video concludes by stressing the importance of recognizing these factors when assessing a patient's risk for periodontal disease and the necessity for good oral hygiene to prevent the disease.

Dark brown or black stains are often due to tobacco use, and yellow-brown stains can result from the use of chlorhexidine and stannous fluoride.
Green and yellow stains on anterior teeth can be caused by poor oral hygiene or chromogenic bacteria, which form color and are difficult to remove.
Malocclusion, such as crowding, can contribute to plaque accumulation and indirectly to periodontal disease.
Prominent roots and missing teeth can lead to food impaction and plaque retention, affecting the patient's bite and potentially causing problems.
Faulty restorations, such as overhanging or rough margins, can contribute to periodontal disease by creating environments for plaque retention.
Over contoured restorations are worse for gingival health than under contoured ones, as they form plaque retentive areas that are hard to clean.
Subgingival margins, even when not faulty, can cause plaque accumulation and gingival inflammation due to their location.
Dental appliances like removable partial dentures and braces can increase plaque retention and affect periodontal health.
Oral jewelry and aggressive horizontal brushing can cause recession, pocket formation, and bone loss.
Self-inflicted injury through improper habits like using toothpicks aggressively can damage gingival tissues and increase the risk for periodontal disease.
Without plaque bacteria, periodontal disease cannot occur, so a combination of factors and poor oral hygiene can make a patient high-risk.
