It is commonly believed that upward/backward forces applied to the condyle by a chin-cap cause temporomandibular dysfunction (TMD). In the current study the long-term follow-up (2-11 years) of patients treated with a chin-cap was investigated regarding signs and symptoms of TMD. The treatment group consisted of 32 individuals who had a skeletal Class III malocclusion treated using chin-cap ther...

OBJECTIVE To investigate the dentoskeletal factors which may predict soft-tissue chin strain during lip closure. METHODS The pretreatment frontal and lateral facial photographs and lateral cephalograms of 209 women (aged 18-30 years) with Angle's Class I or II malocclusion were examined. The subjects were categorized by three examiners into the no-strain and strain groups according to the sof...

Purpose: To statistically evaluate circumpubertal changes in AP chin position and to predict the AP changes in chin position based on morphological indicators previouslyused to successfully predict true rotation. Method: A mixed-longitudinal sample of200 untreated subjects from the Montreal Growth Study was utilized, including 97females and 103 males between 10-13 and 12-15 year...

BACKGROUND Scarring following acne vulgaris is common and can be of profound psychosocial consequence. AIMS AND OBJECTIVES We have clinically noted a variant of acne scarring, overlooked by previous categorisation schemes, which we have denominated as papular acne scars of the nose and chin. We sought to characterise these novel entities further. MATERIALS AND METHODS Initially, we identifi...

Background: Although neurosensory disturbances after genioplasty have been evaluated in different studies, standardization for testing and grading of neurosensory injuries is lacking. For this reason, the incidence of neurosensory disturbance varies from 0% to 100%, depending on the definition of nerve damage, the sensitivity of the diagnostic test method, and the follow-up period. Therefore, t...

AIM To systematically search the literature and assess the available evidence for the influence of chin-cup therapy on the temporomandibular joint regarding morphological adaptations and appearance of temporomandibular disorders (TMD). MATERIALS AND METHODS Electronic database searches of published and unpublished literature were performed. The following electronic databases with no language ...

Lalit Bhutani in the last issue of the U L (45:67) has noted the relative sparing of the underside of the chin and the circumocular region and the upper lip in lepromatous patients and the more severe involvement of the malar eminence, the forehead, and the chin. He attributes this variation to the possible effect of photosensitivity. Sabin (Arch. Neurol. 20 [March 1969]; and U L 37 [1969]) des...

Numb chin syndrome, also known as mental nerve neuropathy, is a rare sensory neuropathy characterized by paresthesia and hypoesthesia in the area supplied by the mental nerve and its branches. This syndrome may be the first symptom of underlying malignancy or the first sign of recurrence and metastasis in patients with preexisting cancer. In this article, we present two cases with bilateral num...

Animal study findings have revealed that individual fat depots are not functionally equivalent and have different embryonic origins depending on the anatomic location. Mouse bone regeneration studies have also shown that it is essential to match the Hox code of transplanted cells and host tissues to achieve correct repair. However, subcutaneous fat depots from any donor site are often used in a...

Chin caps have been used for the correction of primary anterior crossbites, but previous studies of the treatment effects have highlighted problems such as pressure on the temporomandibular joint (TMJ). Therefore, to reduce pressure on the TMJ, a functional orthodontic appliance, the Yanagisawa Class III (YC3) shield was developed to improve the overjet in the primary dentition. The aim of this...
