Reviewer 2 Report
Comments and Suggestions for AuthorsThe authors present detailed and novel research, but they should clarify the following and do general editing of the text:
- In the Introduction part, the author should correct
- Scientific Accuracy & Coherence (Line 53-58) "Among the numerous nanomaterials being researched, nano-silica has developed as a particularly interesting user." (Line 55) Correction: "Among various nanomaterials, nano-silica has emerged as a promising additive for GIC reinforcement."
- The transition from GIC limitations to nano-silica benefits (Lines 53-58) needs better logical flow. Clearly explain why nano-silica is the preferred choice over other reinforcements.
- Methodology Clarification (Lines 60-63) The sol-gel method is introduced (Lines 60-63), but the text should briefly justify why it is preferred for dental applications. A sentence explaining its advantages (e.g., better control over particle size and morphology) would enhance clarity.
- Clinical and Future Research Relevance (Lines 73-77) The objective statement (Lines 73-77) should briefly highlight the clinical impact of the study and suggest future research directions, such as long-term biocompatibility and scalability of nano-silica integration in GICs.
- Comparative Interpretation (Lines 120-122) – Explain why NANO-SILICA5% led to the highest thickness and NANO-SILICA1% the lowest—was this expected based on material properties?
- (Lines 236-240) The author should Mention if temperature and stirring speed were controlled during pH adjustment.
- Titration Conditions (Lines 236-240) pls Mention if temperature and stirring speed were controlled during pH adjustment.
- Correction of P-Value Format (Line 179) – Change "P<0.000" to "P<0.001" for correct statistical reporting.
- Clarify Statistical Findings (Lines 181-185) – Explain why NANO-SILICA1% and NANO-SILICA5% had significantly lower tensile strengths—was it due to particle dispersion, bonding issues, or material brittleness?
- Tukey’s HSD Test Interpretation (Lines 182-183) – Since CONTROL and NANO-SILICA3% showed no statistical difference, discuss if NANO-SILICA3% is an optimal reinforcement level.
- In the conclusion section, the author should include a discussion on the study's limitations and future research directions.
