OBJECTIVES To evaluate two-year results of small-incision lenticule extraction (SMILE) for correction of high myopia. MATERIALS AND METHODS Forty-five eyes of 35 patients with mean spherical equivalent (SE) of -7.10±0.95 D who underwent routine SMILE by a single surgeon and were followed for at least 2 years were analyzed by retrospective chart review. SMILE was performed with a Visumax femto...

The objectives of this study were to evaluate (1) the impact of maxillary incisor inclination on the aesthetics of the profile view of a smile, (2) to determine the most aesthetic inclination in the profile view of a smile and correlate it with facial features, and (3) to determine if dentists, orthodontists, and laypeople appreciate differently incisor inclination in smile aesthetics. A smilin...

This paper describes a multi-agent, intelligent learning environment. The system is called F-SMILE and is meant to help novice users learn how to manipulate their file store. F-SMILE consists of a User Modelling (UM) Agent, an Advising Agent, a Tutoring Agent and a Speech-driven Agent. The UM Agent constantly observes the learner and in case it suspects that the user is involved in a problemati...

BACKGROUND Hyperactivity of depressor septi nasi muscle leads to smiling deformity and nasal tip depression. Lateral fascicles of this muscle help in widening the nostrils. The purpose of this study was to evaluate the relationship between the nasal length changes and the alar base and the alar flaring changes during smile. METHODS Standard photographs are performed in the face and lat...

Smile is an expression of happiness, self-confidence, kindness and beauty. Along with teeth and lips, gingiva is also a vital component of smile. Melanin induced gingival hyper pigmentation may appear un-aesthetic especially when it is associated with high smile line, upper anterior labial segment and is uneven in appearance. It affects individuals from all races. Generally, it is believed that...

Gingival health and appearance are essential components of an attractive smile. Gingival pigmentation results from melanoblastic activity. ‘Black gums’ are common esthetic problem particularly in patients who have a very high smile line (gummy smile). Different treatment modalities have been reported for depigmentation of gingiva such as bur abrasion, scraping, partial thickness flap, cryothera...

Introduction: The aim of this study was to evaluate the role of teeth and lips in the perception of smile esthetics.   Materials and Methods: Thirty women, ranging between 20 and 30 years of age, all with Class I canine and molar relationships and no history of orthodontic treatment, were chosen. Five black and white photographs were taken of each participant in a natural head position while s...

The objective of this prospective study was to investigate outcomes of a lip repositioning technique for the treatment of excessive gingival display by limiting the retraction of the elevator smile muscles. One of the most important goals of clinicians is to meet the esthetic expectations of the patients. Excessive gingival display during smiling is defined as gummy smile; and lip repositioning...

This clinical study examined objective smile parameters in the natural anterior dentition. Standardized intraoral and extraoral photographs were taken of 106 Caucasian adults (54 women, 52 men) with a healthy dentition. The following parameters were analyzed: correlation of dental and facial midline, upper lip position and curvature, relationship of the maxillary anterior incisal curve with low...
