The Effect of Salivary pH on Shear Bond Strength of Adhesive Material in Orthodontic Activation of Light (In Vitro)

Introduction

The success of orthodontic treatment is heavily reliant on the ability of adhesive material to transfer loads through brackets, adhesive, and tooth enamel. Failure in the bonding bracket process can lead to increased clinical working time, long-term extension of treatment, and decreased efficiency. Moreover, orthodontic treatment is also faced with the problem of increased risk of dental caries. In poor carogenic conditions and oral hygiene, the pH of saliva tends to decrease due to carbohydrate fermentation. This low pH condition can cause changes in the enamel, which is thought to affect the strength of the adhesive bonding material used in the treatment of close orthodontics.

The Importance of Adhesive Material in Orthodontic Treatment

Adhesive material plays a crucial role in orthodontic treatment, and its success is dependent on its ability to bond with tooth enamel. The failure of adhesive material can lead to a range of complications, including increased clinical working time, long-term extension of treatment, and decreased efficiency. In addition, orthodontic treatment is also faced with the problem of increased risk of dental caries. In poor carogenic conditions and oral hygiene, the pH of saliva tends to decrease due to carbohydrate fermentation. This low pH condition can cause changes in the enamel, which is thought to affect the strength of the adhesive bonding material used in the treatment of close orthodontics.

The Effect of Salivary pH on Shear Bond Strength

This study aims to determine the strength of shear bonds (shear bond strength) of the adhesive material of orthodontic which is activated by light in various pH conditions, namely normal, critical, and carogenic. In addition, this study also wants to reveal the impact of saliva pH on the strength of the adhesive material. The method used in this study is in vitro experiments with a total sample of 27 upper jaw premolar teeth. After the bracket is installed using adhesive material activation of light, the sample is divided into three groups based on the pH of the soaking media, namely pH 4.5, 5.5, and 6.7, for seven days. The results obtained were analyzed by Kruskal-Wallis and Mann Whitney statistical methods.

Results

The results showed that a decrease in salivary pH caused a decrease in shear bond strength. There are significant differences in the average shear bond strength at normal pH (13.68 ± 2.36 MPa), critical PH (6.58 ± 1.59 MPa), and Carogenic PH (2.95 ± 0.57 MPa). The conclusion of this study indicates that the pH of saliva has a significant influence on the strength of the shear bonds of the orthodontic adhesive material activation of light.

Analysis

This study highlights the importance of maintaining a pH balance in the mouth to support the success of orthodontic care. Decreased pH that occurs in the long run due to high carbohydrate diet and inadequate dental hygiene can increase the risk of bonding failure, which not only affects the duration of treatment but also overall dental health. When the enamel surface becomes more acidic and causes demineralization, the bond between brackets and enamel is getting weaker. This explains why it is important for orthodontic patients to maintain oral hygiene and conduct routine checks so that the Saliva pH remains in a healthy range.

Practical Implications

The findings of this study provide very valuable insights for dentists and orthodontists. With a better understanding of how the saliva pH affects the strength of the adhesive bonding material, professionals can provide better advice to patients about dental care and proper oral hygiene maintenance. Furthermore, this research can also open the way for further studies on the development of adhesive materials with compositions that can adapt to salivary pH fluctuations, thereby increasing the success of orthodontic care.

Conclusion

In the face of increasing caries cases among orthodontic patients, it is essential to take a multidisciplinary approach that not only focuses on orthodontic care but also in the overall oral health aspect. This effort can help optimize the results of orthodontic care and minimize the risk of complications that may arise later on.

Recommendations

Based on the findings of this study, the following recommendations are made:

  • Patients should maintain good oral hygiene and conduct routine checks to ensure that their saliva pH remains in a healthy range.

  • Further studies should be conducted on the development of adhesive materials with compositions that can adapt to salivary pH fluctuations.
  • A multidisciplinary approach should be taken to optimize the results of orthodontic care and minimize the risk of complications.

Limitations

This study has several limitations, including:

  • The sample size was limited to 27 upper jaw premolar teeth.
  • The study only examined the effect of salivary pH on shear bond strength in vitro.
  • Further studies are needed to confirm the findings of this study and to explore the effect of salivary pH on shear bond strength in vivo.

Future Directions

This study provides a foundation for further research on the effect of salivary pH on shear bond strength. Future studies should aim to:

  • Examine the effect of salivary pH on shear bond strength in vivo.
  • Develop adhesive materials with compositions that can adapt to salivary pH fluctuations.
  • Investigate the impact of salivary pH on the success of orthodontic care.
