During the harvesting of cut-stem vegetables, structural parameters cutters have an important influence on effect. Structural stalks directly affect cutting effect cutter. The thickness stalk xylem has a strong stability and surface In this paper, broccoli conventional toothless was investigated using as object. It found that thicker leads to shear force fluctuations, which in turn affects smoo...

Background: The fluoride drug is mentioned as a double-edged weapon due to its positive and negative outcomes. Reducing dental caries in large population, cost effective excess teeth or body may lead systemic diseases even death. Dental erosion affects the hard tissues of rendering them vulnerable decay. Methods & Materials: A school based descriptive cross-sectional survey. Purposive sampl...

primary tooth impaction is a rare finding during the development of primary dentition. several factors contribute to the impaction of a deciduous tooth. this report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. this tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the prem...

Aim: To investigate the prevalence of eight morphological and numerical anomalies in the southern Chinese permanent dentition and to compare these with studies from different populations. Materials and Methods: The material used in the study consisted of study models and panoramic radiographs collected from 725 randomly selected 12-year-old children (358 males and 367 females). The anomalies we...

Currently clinicians advice rotational panoramic radiography (RPR) for preliminary investigation. Despite few inherent limitations, rotational panoramic radiography still remains the diagnostic tool of choice. Abnormal structures such as a supernumerary tooth or a device falling within the certain central regions in conventional RPR images may mislead the clinicians towards an inaccurate diagno...

In this work we studied some of the main effects of the bone tissue behaves in different ways according to dry or humid conditions. This research intended to evaluate stress transmission in dog mandibles, through holographic interferometric double exposition method, in such conditions: fresh, formalin fixed and macerated [4]. The analysis made about fringes patterns on the surface of jaw and de...

Aim: To investigate the prevalence of eight morphological and numerical anomalies in the primary dentition of southern Chinese and to compare the prevalences with those from different ethnic groups. Materials and Methods: The material used in the study consisted of plaster casts and standardized panalipse radiographs collected from 936 randomly selected 5-year-old children (493 males and 443 fe...
