Desensitizing agents

Dentine hypersensitivity is a terminology that has been used to describe a recurrent painful condition of the teeth for decades. Despite this, researchers seem to have a range of concerns involving dentine hypersensitivity. This might not be surprising, however, that one might still sympathize with Johnson and colleagues' assertion in 1987 that dentine hypersensitivity is an enigma, a condition that is frequently encountered but poorly understood.

Rate of prevalence: 15-18% of the general population; 72-98 percent of periodontal patients. Peak incidence is between 20 and 40 years old, with a range of 20 to 50 years old. (The presence and advancement of gingival recession are the reasons.)

Gender: Females are impacted at a higher rate than males. Females have superior oral hygiene than males for many reasons—nutritional differences, with females selecting healthful but often acidic foods and beverages. Periodontal illness and periodontal therapy, presumably through their effects on dentine and gingival recession, predisposed to extreme dentine sensitivity.

Teeth are distributed in the buccal cervical region. Due to the location of gingival recessions and where the enamel is thinnest, this site is predisposed to receding gums. Canines and first premolars are more commonly affected, followed by incisors and second premolars. Molars are the least widely affected. The plaque scores are negatively correlated with the plaque scores. Compared with their suitable contralateral tooth types, left side teeth are significantly more sensitive.

Calcium carbonate

If calcium in your diet isn't adequate, you can take calcium carbonate as a dietary supplement. To maintain a healthy nervous system, heart, muscles, and bones, the body needs calcium. In addition to treating heartburn, acid reflux, and upset stomach, calcium carbonate acts as an antacid.

Surface stains, plaque, and debris can easily be removed with this abrasive. By scrubbing your teeth with an abrasive and your toothbrush, your teeth are cleaned. Having them on your teeth after brushing is what makes them smooth and clean. Additionally, they may also help whiten your teeth! In toothpaste, calcium carbonate is not the only abrasive; dehydrated silica gel, hydrated aluminum oxides, magnesium carbonate, and phosphate salts are also utilized as abrasives. As rough as they are, these abrasives remove plaque without damaging your tooth enamel.

Sodium fluoride

It is safe and effective to use toothpaste and mouthwash containing sodium fluoride when formulated correctly and used as directed to prevent tooth decay. As a result of its fluoride content, tooth enamel is less prone to demineralization and is more likely to remineralize, strengthening it.

Preventing cavities is the purpose of this medication. It strengthens the teeth and ensures that they are less susceptible to decay from acid and bacteria. Infants younger than six months of age are not recommended to use this medication. When the water supply contains more than 0.6 parts per million fluorides, this medication is not recommended for use. Based on your age and your water's fluoride content, your dosage differs.

Zinc eugenol cement

A zinc oxide-eugenol cement (IRM) filling could be temporary until a semi-permanent restoration is completed in the future. Typically, temporary cement filling is constructed of this low-strength base. Zinc oxide is the primary material in the powder, while eugenol is the main substance in the liquid, along with olive oil for plasticizing.

A cement of low strength has been used extensively in dentistry since the 1890s, called zinc oxide eugenol (ZOE). Furthermore, they are considered the least irritating among all dental cement and are known to have an enormous effect on the exposed dentin.

The zinc eugenol cement can be classified as follows:
  • For temporary cementation, Type I ZOE
  • Permanent Cementing: Type II ZOE
  • Thermal base and temporary filling of type III ZOE
  • Cavity Liners: Type IV ZOE cement come in powder and liquid or two-paste varieties
