Once in a while, new innovations emerge in the world of restorative dentistry. The emergence of new bonding agents, dental liners and bases, and adaptive capabilities of components offer new opportunities.
Dental liner materials have improved tremendously over the last few years. They are applied in a thin layer to seal the walls of the cavity or minimize the influx of bacteria following restorative procedures. On the other hand, dental bases are applied in thick layers and support a restorative material during the placement as well function. The dental liners and bases are widely used to improve the outcome of dental caries treatment and several dental restoration procedures.
According to Allied Market Research, the global dental liners and bases market is expected to reach $1.99 billion by 2030, growing at a CAGR of 4.1% from 2021 to 2030.
The use of dental liners and bases has changed. At first, their use was limited only after the placement of final dental restoration to protect tooth and pulp. However, over the years, the applications of dental liners and bases have improved and their toxic effects are minimized. They are necessary to minimize the risk of bacterial infection after the procedure and limit postoperative pulpal inflammation.
Benefits of using dental liners and bases:
1. Prevents microleakage: Current formulations of dental liners and bases are effective and offer a stronger bond to the dentin compared to traditional glass ionomers, which led to leakage under the composite. However, the new, improved liners and bases product seal the tooth and bond strongly to the restoration, which ultimately reduces the incidence of microleakage between tooth and restoration.
2. Inhibits bacterial growth: A proper dental restoration using advanced liners and bases prevents leakage underneath the restoration, which eliminates the risk of bacterial infection. Moreover, the uptake of fluoride by tooth tissue led to the reduction of artificial root surface caries.
3. Easy and quick replacement: There are tons of varieties of liners and bases, in different forms and delivery systems. Several manufacturers offer the dispensing option which helps reduce preparation time. On the other hand, some materials can be mixed beforehand to offer consistency and the same chemical makeup during every use.
The materials of dental liners, bases, and cement are constantly improving and changing. New formulae come into the light depending upon the need of the procedure. Thus, one must consult their doctors regarding the chemical makeup of the liners and bases and choose the most suitable post-operation.
Dentists utilize dental liners/bases to improve the outcome of treating dental caries along with other dental restoration procedures. Manufacturers of dental materials are constantly introducing new versions of existing products (including addition of polymers and silver in the prime material), and research studies are being conducted to analyze the efficacy of these newly introduced dental liners/bases. Thus, with increase in number of dental restoration procedures, the need for new dental liners/bases material has also emerged. In addition, surge in demand for dental liners/bases materials exhibiting bactericidal properties has been witnessed over the years, which is expected to propel the market growth.
