Refractive surgery causes only minimal size differences, similar to contact lenses. In a study performed on 53 children who had amblyopia due to anisometropia, surgical correction of the anisometropia followed by strabismus surgery if required led to improved visual acuity and even to stereopsis in many of the children [9] (see: Refractive ...
Lip licker's dermatitis is a type of skin inflammation around the lips due to damage by saliva from repetitive lip licking and is classified as a subtype of irritant contact cheilitis. [ 1 ] [ 2 ] The resulting scaling, redness , chapping , and crusting makes a well-defined ring around the lips .
The dentist will necessitate the trimming of the inner portion of the lower TBA specifically the area behind the lower front teeth in order to alleviate any pain on the tissue. [ 14 ] During the expansion phase, the acrylic behind the upper front teeth may also be trimmed to provide a limited amount of spontaneous alignment or uprighting of the ...
It provides motor innervation to muscles of the lower lip and chin: the depressor labii inferioris muscle, depressor anguli oris muscle, and mentalis muscle. [1] It communicates with the mental branch of the inferior alveolar nerve. [citation needed]
Chapped lips (also known as cheilitis simplex [5] or common cheilitis) [6] is characterized by the cracking, fissuring, and peeling of the skin of the lips, and is one of the most common types of cheilitis. [5] [7] While both lips may be affected, the lower lip is the most common site. [7]
Diagramatic representation of mucosal erosion (left), excoriation (center), and ulceration (right) Simplistic representation of the life cycle of mouth ulcers. An ulcer (/ ˈ ʌ l s ər /; from Latin ulcus, "ulcer, sore") [2] is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue. [3]
The commissure is the corner of the mouth, where the vermillion border of the superior labium (upper lip) meets that of the inferior labium (lower lip). The commissure is important in facial appearance, particularly during some functions, including smiling. As such it is of interest to dental surgeons.
The depressor labii inferioris muscle may be resected (cut and removed) using surgery to correct an asymmetry of the lower lip when smiling. [1] This asymmetry can be caused by paralysis of the marginal mandibular branch of the facial nerve on one side, so the healthy side may be cut to create symmetry. [ 1 ]
