Comparison of Peri-Implant Soft Tissue Around Zirconia and Titanium Abutments in the Aesthetic Zone: A Narrative Review.

This narrative review compares the peri-implant soft tissue responses around zirconia and titanium abutments in the aesthetic zone, emphasizing their mechanical, biological, and aesthetic properties. Titanium abutments, known for their excellent mechanical strength and fatigue resistance, have traditionally been the standard in dental restorations but face challenges in aesthetic integration due to their metallic appearance and potential for higher inflammatory responses. Zirconia abutments, emerging as a promising alternative, offer superior aesthetic outcomes, reduced plaque accumulation, and lower inflammatory responses, making them ideal for use in visible areas with thin soft tissue biotypes.

Comparison of orthodontic treatment need among professionals and parents in Dammam, Saudi Arabia.

Aims: This study aimed to assess parents' awareness and attitude regarding their children's malocclusion compared with professional assessments and to measure the prevalence of malocclusion among children in Dammam, Saudi Arabia.

Methods: The study population consisted of 377 randomly selected children (aged 8-12 years) from five schools in Dammam, Saudi Arabia. A questionnaire was used to assess parents' awareness using the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) and knowledge about preventive orthodontics.
