The width and length of the anterior teeth, the dimensions of the frontal dental arches and the dimensions of the hard palate were measured (24 men and 56 women, age range of 18-30 years). The results showed gender-related dimorphism only for the cervical width of the maxillary canine, which were wider in men, p < 0.05. The width-to-length ratios of the maxillary frontal teeth varied from 0.82 ...

Ph: 09448-091115 The present study investigated the effect of masseter muscle thickness on maxillary dental arch width and growth pattern of face. Sample comprised of 40 patients, (20 females, 20 males) between 18 to 23 years. They were subdivided accordi...

BACKGROUND To determine the association between the thickness of masseter muscle and the maxillary dental arch width. To explore the influence of gender on masseter muscle thickness. MATERIALS & METHODS Seventy subjects (35 females and 35 males) of age 18 to 25 years were selected for the study based on class I molar relationship. The masseter muscle thickness of the right and left sides in e...

BACKGROUND The aim of this study was to determine arch width changes during maxillary first premolars extraction and non-extraction treatment in patients with Class II division 1 malocclusion. MATERIAL AND METHODS Dental casts of 91 Class II division 1 patients (36 males and 55 females) were evaluated. The minimum age of the subjects at the beginning of treatment was above 16 years. 48 patien...

  In this study two groups of dental study models were selected to evaluate the relationship between the tooth size, arch dimensions , and dental crowding. The first group consisting of 56 pairs of dental study models (28 males and 28 females) with normal occlusion ( without dental crowding) ranging in  age from 16 to 20 years, were selected among 4445 students from Kerman by multi stage rando...

This study investigated the expansion of the carpal tunnel resulting from the application of palmarly directed forces to the transverse carpal ligament (TCL) from inside the carpal tunnel. Ten fresh-frozen cadaveric hands were dissected to evacuate the carpal tunnel, and thus to expose the TCL. A custom lever device was built to apply forces, ranging from 10 N to 200 N, to the TCL. Without forc...
