Among ray-finned fishes (Actinopterygii), the crushing, durophagous feeding strategy first evolved in early Carboniferous period, with †Eurynotiformes possessing dentitions single layers of partially to fully fused blunt teeth. In †‘Platysomidae’ (Permian), a new form crushing dentition (phyllodonty), which multiple superimposed teeth developed intraosseously, within jaw. The phyllodont is also...

Human teeth are diphyodont excepting the permanent molars. The deciduous teeth are, ontogenetically considered, the first generation of teeth. The permanent teeth (except molars) belong to the second dentition. The term " third dentition " (also called the postpermanent dentition) refers to the opinion that one more set of teeth can occur in addition to the permanent teeth. The processes by whi...

The aim of this study was to assess the individual and grouped influence of host-related factors on dental caries experience in permanent dentition of 7-9 year-old children. One hundred and twenty one children were recruited applying a stratified cluster sampling without replacement. Clinical examinations, Colorimetric Test and non-stimulated and stimulated saliva collection were performed; the...

We have developed a new orthodontic bracket with three slots with lubricative properties on the working surfaces and proposed a new orthodontic treatment system employing 0.012-0.014-inch Ni-Ti arch wires. We recruited 54 patients, of which 27 received treatment with the new zirconia bracket with multiple slots system (M group), and the others received treatment with standard edge-wise applianc...

PURPOSE This study determined the vertical response of class III patients in the primary, mixed, and late mixed dentition phases fitted with a protraction mask and expansion. METHODS The before and after cephalometric records of 112 patients divided by sex were analyzed at ages 3 to 6, > 6 to 9 and > 9 to 12 years to assess the vertical changes. Data was correlated by means of paired t tests ...

Dental crowding is the most common form of malocclusion. It more pronounced in mandible than maxilla and tends to increase with age. Depending on degree space deficiency age children prevalence dental can be as high 50%. Schwartz appliance lip bumper have been widely used an early treatment for increasing lower arch dimensions. The aim this review evaluate scientific research about efficacy com...

An increased number of teeth in relation to normal dental formula is called hyperdontia, and the additional tooth are termed as supernumerary tooth. A supplemental a that closely resembles shape its adjacent with which they associated supplements for occlusion. Primary dentition presents lower prevalence compared permanent dentition.

INTRODUCTION This article illustrates a new treatment approach and evaluates the effect of use of fluoridated toothpaste on the remineralization of white spot lesions (WSLs) diagnosed at debonding. MATERIALS AND METHODS Thirty-one orthodontic patients (mean age: 19.6 years), with a minimum of four WSLs on the buccal surfaces of the maxillary and mandibular incisors, canines, premolars and fir...
