A shear bond strength test workshop improved dental students' performance and confidence in adhesive dentistry. The hands-on exercise demonstrated proper bonding techniques, leading to significant improvements in bond strength and self-rated confidence.
Area of Science:
- Dental Education
- Materials Science in Dentistry
- Restorative Dentistry
Background:
- Teaching dental students proper bonding agent protocols for composite restorations in preclinical settings presents challenges in translating technique to clinical outcomes.
- Assessing the effectiveness of practical application and its impact on student confidence in adhesive dentistry is crucial for improving dental education.
Purpose of the Study:
- To examine the effectiveness of a shear bond strength test in improving dental student performance and confidence in adhesive dentistry.
- To evaluate the impact of a hands-on workshop utilizing a bond strength testing instrument on student understanding of adhesive dentistry principles.
Main Methods:
- A hands-on shear bond strength workshop was conducted for 212 third- and fourth-year dental students at UCLA School of Dentistry.
- Eighty-eight students participated, performing bonding procedures with a bond strength testing instrument to assess technique and outcomes.
- Student performance was evaluated through shear bond strength measurements between first and second attempts, and self-rated confidence was assessed before and after the exercise.
Main Results:
- A significant difference in mean shear bond strength was observed between the first and second attempts for the total student group (p<0.001) and fourth-year students (p<0.001).
- Third-year students showed an increase in mean shear bond strength, though not statistically significant (p=0.097).
- Aggregate self-ratings revealed a significant increase in student confidence and agreement that the exercise enhanced their understanding and performance in adhesive dentistry (p<0.001).
Conclusions:
- The shear bond strength test workshop served as an innovative method to emphasize proper technique in adhesive dentistry for dental students.
- The hands-on exercise effectively enhanced student confidence in performing bonding procedures within the preclinical laboratory setting.
- Utilizing objective testing like shear bond strength assessment can improve the translation of preclinical skills to clinical application in restorative dentistry.

Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
