An investigation of Y-TZP surface characteristics and adhesive properties following treatment with Tri-biochemical Silica Coating, Femtosecond Laser, and Nano-hydroxyapatite: A scanning electron microscopy evaluation.
Objectives: To examine how advanced surface pretreatment techniques - Tribochemical silica coating (TBC), Femtosecond laser (FS), and Nano-hydroxyapatite (HA) coating - affect the surface roughness (Ra) and shear bond strength (SBS) between resin luting cement and Yttria-stabilized tetragonal zirconia polycrystals (Y-TZP).
Methods: The lab-based comparative study was approved by the ethical committee of King Saud University under IRB number F98-971X9 and was completed in three months (June to September, 2024). Eighty-four YTZP zirconia discs were created and sorted into four groups based on different conditioning agents: Group-I (APA) as the control, Group-II (TBC), Group-III (FS laser), and Group-IV (Nano-HA coating). Ra was measured on five discs from each group using a profilometer, while surface topography was examined through SEM analysis. Ten specimens per group were bonded with luting cement, followed by SBS testing and fracture mode analysis using a universal testing machine and stereomicroscope, respectively. One-way ANOVA with post hoc Tukey tests (p<0.05) was used for statistical analysis of Ra and SBS means across the groups.
Results: Group-IV (Nano-HA coating) exhibited the highest Ra and SBS values. Conversely, Group II (TBC) displayed the lowest Ra and weakest bond strength.
Conclusion: Nano-HA coating and FS laser can be employed as viable alternatives to APA without compromising the physical and mechanical properties of zirconia ceramic.
期刊介绍：
It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad.
Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
