We study imaging systems designed to assess the smile of laser diode bars (LDBs). The magnification matrix is derived from the required sampling period and the geometries of the LDBs and the charge-coupled device (CCD) array. These image-forming systems present in-plane pure translation invariance, but in the case of anamorphic ones, lack in-plane rotation invariance. It is shown that the smile...

Objective: Determine the lip position influence on dental aesthetics in adults older than 19 years according to academic publications last 5 years. Material and methods: A systematic research was carried out medical literature (UNAM, Cochrane, BVS, Scielo, PubMed), using following search strategy: (lip line) OR (smile AND (parameters) (analysis) (evaluation) identify articles that reported data...

AIM This study aimed to investigate the existence of the golden proportion, recurring esthetic dental (RED) proportion and golden percentage between the frontal view widths of the maxillary anterior natural dentition among students of Indian origin by the aid of digital photography. MATERIALS AND METHODS This study was conducted with 80 dental students (41 female and 39 male), with ages rangi...

A smile is a form of one's facial expression that widely used and easy to see. Having an aesthetic attractive can make person more confident when interacting socially in their environment. There are eight main components assessed smile, two which the arc gingiva display. Both have received lot attention because they known major influence on smile.The harmony gingival display will produce smile....

key elements of orthodontic diagnosis and treatment planning over the last decade.1-3 Recent advances in technology now permit the clinician to measure dynamic lip-tooth relationships and incorporate that information into the orthodontic problem list and biomechanical plan. Digital videography is particularly useful in both smile analysis and in doctor/patient communication. Smile design is a m...

PURPOSE To characterize the early ocular-surface changes or tear inflammatory-mediators levels following small-incision lenticule extraction (ReLEx smile) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS Forty-seven myopic subjects were recruited for this prospective study. Fifteen underwent ReLEx smile and thirty-two underwent FS-LASIK. Corneal fluorescein (FL)...

BACKGROUND To investigate accommodative response and accommodative lag changes after femtosecond laser small incision lenticule extraction (SMILE) for moderate to high myopia correction. METHODS A total of 32 eyes of 32 patients with no strabismus who underwent SMILE were enrolled in this prospective clinical study. The accommodative response was obtained viewing monocularly with spherical eq...
