Role of Dentofacial Harmony among Young and Old Adult Females in Smile Perception of Dental Specialists and Laypeople: A Cross-Sectional Study.

Introduction: The purpose of this study was to determine whether balance and harmony of the face, when seen as a whole, alter the smile perception as compared to a lone standing smile in female subjects of two age groups and to identify parameters of dental composition and dentofacial harmony associated with the smile perception of dental specialists (DS) and laypeople (LP).

Settings And Design: A cross-sectional study.

Materials And Methods: Twenty-nine DS and 29 LP scored the smile attractiveness of 84 full-face images (FFIs) and corresponding smile images (SIs) of young adults (YA: 20-29 years) and old adults (OA: 50-59 years), using the Visual Analogue Scale.

Novel prosthodontic technique in fabrication of customized nasal stent in an infant.

Burn injuries have a major impact on the physical and functional aspects of patients, thereby affecting their quality of life. Nasal stenosis which occurs as a result of wound contraction may lead to serious complications if not intervened at the earliest. In the prosthodontic front, nasal stents may be utilized in conjunction with reconstructive surgery procedures to minimize scar contraction and prevent nasal stenosis.

Finite Element Analysis of effect of cusp inclination and occlusal contacts in PFM and PEEK implant-supported crowns on resultant stresses.

Background: Effect of prosthesis design on occlusal overload and long-term implant stability cannot be overstated. In Porcelain Fused to Metal (PFM) crowns, low cusp inclination and occlusal contacts limited to central fossa ensure axially directed forces on an implant but often pose esthetic and functional challenges. It is theorized that resilient Polyetheretherketone (PEEK) crowns have shock absorption capacity for favorable stress distribution.
