Summary
Dentine hypersensitivity in children is linked to dental erosion and reduced salivary flow. Bitter taste and oral hygiene also play a role, highlighting the importance of dental erosion factors.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Oral Medicine
Background:
- The causes of dentine hypersensitivity (DH) remain unclear, with limited research in pediatric populations.
- Understanding DH etiology in children is crucial for effective prevention and management strategies.
Purpose of the Study:
- To investigate clinical, dietary, and salivary factors associated with dentine hypersensitivity in children.
- To identify potential risk factors for DH in a pediatric cohort.
Main Methods:
- A study involving 48 children assessed DH complaints, dietary habits, and dental erosion.
- Salivary parameters (flow rate, pH, buffering capacity, calcium, phosphate) and oral hygiene (OHI-S) were evaluated.
- Statistical analyses, including Poisson regression, identified factors associated with DH.
Main Results:
- Dentine hypersensitivity was significantly associated with dental erosion and lower salivary flow rates.
- When dental erosion was excluded, bitter taste perception and oral hygiene index (OHI-S) remained significant factors.
- Prevalence ratios (PR) and 95% confidence intervals (95% CI) quantified these associations.
Conclusions:
- Dentine hypersensitivity in children is multifactorial, with dental erosion being a key associated factor.
- Salivary flow rate, bitter taste perception, and oral hygiene status also contribute to DH in pediatric patients.

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...

01:29Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
268
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...

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...

8.6K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

01:29Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

01:23Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
