As a modern tooth cleaning and beauty method, biological sea salt sandblasting technology has gradually attracted attention in the field of oral care. This technology physically cleans the tooth surface by spraying fine particles containing natural sea salt ingredients to remove dental plaque and pigment deposition. However, for dentin, the internal structure of the tooth, the impact and safety of biological sea salt sandblasting have become a research focus. This article will combine the anatomical structure of the tooth, the mechanism of action of biological sea salt sandblasting and existing research, and discuss in detail its impact on dentin, providing a theoretical basis for clinical application.
1. Structure and function of dentin
Dentin is an important tissue that makes up the main body of the tooth. It is located below the enamel and surrounds the pulp. Its main components include about 70% inorganic matter (hydroxyapatite crystals), 20% organic matter and 10% water. Dentin is rich in microtubules that connect the pulp to the tooth surface, transmit sensory signals and participate in the nutrition supply and defense response of the teeth.
The protectiveness of dentin depends on the enamel and cementum covering its surface. Once the enamel is damaged, the dentin is exposed, which may lead to sensitivity, pain and increased risk of caries. Therefore, any tooth surface treatment technology must consider the protection of dentin.
2. Technical principle of biological sea salt sandblasting
Biological sea salt sandblasting uses high-pressure equipment to direct a jet of sea salt particles toward the tooth surface, using mechanical friction to remove dental plaque, tartar and surface pigments. Compared with traditional sandblasting materials (such as sodium bicarbonate), biological sea salt is claimed to be gentler and less irritating to teeth and soft tissues due to its natural mineral composition and finer particles.
The natural mineral components of sea salt (such as calcium, magnesium, potassium and trace elements) are believed to assist tooth mineralization and promote the deposition of surface trace minerals, thereby potentially enhancing the surface hardness and acid resistance of teeth.
3. Analysis of the effects of biological sea salt sandblasting on dentin
Effects of mechanical friction on dentin microstructure
Sandblasting can remove dental plaque and may cause slight wear of tooth enamel. If sandblasting is performed improperly or frequently, the enamel may become thinner or even partially damaged, exposing the dentin and increasing the risk of sensitivity and caries.
Current research shows that biological sea salt sandblasting causes less wear on the enamel than traditional sandblasting materials due to its finer particles and lower hardness. However, the spraying pressure and time still need to be controlled to avoid mechanical damage to the enamel and dentin.
Effects on dentin sensitivity
Exposure of microtubules in the dentin is the main cause of dentin sensitivity. After sandblasting, if the protective layer of enamel is intact, sandblasting has no obvious effect on dentin sensitivity. On the contrary, when the enamel is damaged or the gums are receding, resulting in exposed dentin at the neck of the tooth, sandblasting may aggravate the sensitivity symptoms.
Studies have shown that biological sea salt particles have a certain sealing effect on dentin microtubules and can reduce sensitivity to a certain extent, but this effect depends on the mineral deposition and repair ability of the tooth surface after sandblasting.
Potential role of biological sea salt minerals in dentin repair
The mineral elements contained in sea salt, especially calcium and magnesium, contribute to the remineralization process of the tooth surface. During the sandblasting process, these mineral particles can adhere to the tooth surface, promote the formation of hydroxyapatite crystals, and enhance the acid and wear resistance of enamel and exposed dentin.
Some in vitro tests have shown that after biological sea salt sandblasting, the tooth surface showed better mineral deposition, reduced the openness of dentin microtubules, and thus reduced the risk of dentin sensitivity.
Effects on dental pulp and soft tissue
During the sandblasting process, sea salt particles occasionally come into contact with the gums and periodontal soft tissues, which have a significant antibacterial and anti-inflammatory effect and help improve the oral environment. Its low irritation properties make it less likely for soft tissues to have inflammatory reactions. However, if the sandblasting pressure is too high or the operation is improper, it may still cause local mechanical damage to the soft tissues.
IV. Related Clinical Studies and Safety Evaluation
Currently, there are limited clinical studies on the effects of biological sea salt sandblasting on dentin. However, existing studies have emphasized that the standardization of sandblasting operations has a significant impact on dental health. Reasonable control of sandblasting pressure, spray angle and time is the key to reducing enamel wear and protecting dentin.
In a randomized controlled trial, patients who used biological sea salt sandblasting had significantly improved tooth surface smoothness, no significant aggravation of dentin sensitivity symptoms, and some patients reported reduced sensitivity. Another in vitro simulation study found that the microhardness of enamel did not decrease significantly after sandblasting, indicating the mildness of biological sea salt sandblasting.
Nevertheless, sandblasting technology is not suitable for patients with severe enamel defects, exposed dentin or active caries. To avoid adverse reactions, preoperative professional evaluation and individualized treatment plan development can help ensure treatment safety.
5. Operational specifications and clinical application recommendations
To ensure the safety of dentin, biological sea salt sandblasting should follow the following operating principles:
Sandblasting pressure and time control : avoid long-term, continuous sandblasting to reduce enamel wear.
Adjust the spray angle : maintain a proper angle with the tooth surface, and avoid spraying directly on the tooth neck or exposing the dentin.
Preoperative evaluation : Develop a personalized plan based on the enamel status and dentin exposure.
Postoperative care : Encourage the use of fluoride toothpaste to promote tooth remineralization and reduce sensitivity.
Indications : Suitable for patients with mild to moderate dental plaque and pigmentation, not suitable for patients with severe enamel defects.
Beauty Encyclopedia Tips:
Biological sea salt sandblasting is a gentle teeth cleaning technology with a low risk of mechanical damage to dentin, and may promote tooth surface repair and sensitivity relief through mineral deposition. Reasonable and standardized operation and preoperative evaluation are the key to protecting dentin health. When choosing sandblasting treatment, patients should cooperate with the advice of professional dentists, pay attention to postoperative oral care, and maintain long-term dental health.
