Diagnostic value of profile photography in identifying departures from the norm of growth pattern and horizontal jaw relationship.

Background: Although the importance of facial photography in orthodontics has been recognized, there is only one study on its validity and absolutely no studies on its diagnostic value. This study was conducted, therefore, to evaluate for the first time the diagnostic merit of photography in detecting growth pattern and jaw relationships.

Methods: Standardized lateral cephalographs and profile photographs were taken from 54 girls and 26 boys.

The effects of camera lenses and dental specialties on the perception of smile esthetics.

Background And Aim: The purpose of this study was to investigate whether different camera lenses and dental specialties can affect the perception of smile esthetics.

Methods: In the first phase of this study, 40 female smile photographs (taken from dental students) were evaluated by six orthodontists, three specialists in restorative dentistry, and three prosthodontists to select the most beautiful smiles. The 20 students with the best smile ranks were again photographed in standard conditions, but this time with two different lenses: Regular and then macro lenses.

Effects of Three Types of Digital Camera Sensors on Dental Specialists' Perception of Smile Esthetics: A Preliminary Double-Blind Clinical Trial.

Purpose: The effect of image quality or dental specialties on the subjective judgment of facial beauty has not been evaluated in any study. This study assessed the effect of digital sensors and specialties on the perception of smile beauty.

Materials And Methods: In the first phase of this double-blind clinical trial, 40 female smile photographs (taken from dental students) were evaluated by a panel of three prosthodontists, six orthodontists, and three specialists in restorative dentistry to select the most beautiful smiles.

Association between orthodontic treatment need and masticatory performance.

Aim: This retrospective cohort study assessed the differences between the masticatory performance of individuals with and without orthodontic treatment need.

Methods: Masticatory performances of 120 participants with equal numbers of males and females (n = 60 each) with and without treatment need (n = 60 each, determined using the index of the complexity, outcome, and need [ICON]) matched by age and sex were assessed. Participants chewed on test foods at sequences of 20, 30, 40, 40, 30, and 20 masticatory cycles.

Effectiveness of Mouth Washes on Streptococci in Plaque around Orthodontic Appliances.

Background and Purpose. Fixed orthodontics may be associated with accumulation of Mutans Streptococci (MS), enamel demineralization, and an increased number of carious lesions, predominantly in sites adjacent to brackets. This study was undertaken to assess the effectiveness of Listerine, Oral-B, and Ortho-kin on the accumulation of MS in plaque around orthodontic brackets.
