Objective:  To evaluate the effects of unilateral loss lower first permanent molar (L6) on position and development third (L8) .  Material Methods:  Fifty-four panoramic radiographs subjects with L6 were examined. The L8 side was compared in hemiarch without (contralateral). effect positioning examined all samples (n=54), whereas 38 patients incomplete root formation. Signs statistical test use...

The aim of the present work is to study the External and Internal Root anatomy of Egyptian Maxillary First Permanent Molar.180 maxillary first permanent molar were randomly selected with intact roots, minimal occlusal decay, and without fillings. External morphological observations of roots were recorded including the number of roots , root trunk length, Maximum convexity level and the relation...

The aim of this study is to present a new upper molar distalization appliance called Cise distalizer designed as intraoral device supported with orthodontic mini screw for upper permanent molar distalization. The new appliance consists of eight main components. In order to understand the optimum force level, the appliance under static loading is tested by using strain gage measurement technique...

Background: Molar incisor hypomineralization is one of the major developmental defects enamel affecting or more first permanent molars and often associated with involvement. MIH thought to be idiopathic, but etiology not yet known. Objective: The aim this study was determine relationship between postnatal factors, namely disease suffered by children aged 0-3 years in group 6-15 years. Methods: ...

Background: Many clinicians tell me they are seeing more enamel hypoplasia in permanent first molars these days. Some have speculated as to why this may be occurring, with many differing hypotheses emerging. Recently, others have speculated that the recent increase in the use of certain antibiotics in early childhood could have a mineralization effect on permanent first molars and incisors, whi...

Molar incisor hypomineralization (MIH) is a common developmental condition resulting in enamel defects in first permanent molars and permanent incisors. It presents at eruption of these teeth. One to four molars, and often also the incisors, could be affected. Since first recognized, the condition has been puzzling and interpreted as a distinct phenomenon unlike other enamel disturbances. Early...

INTRODUCTION In this research project, we aimed to compare the effectiveness of single (1 deciduous canine) and double (deciduous canine and first molar) extractions in subjects with retained maxillary permanent canines positioned palatally or centrally in the alveolar crest, at risk for root resorption of adjacent permanent teeth. METHODS Subjects at risk for canine impaction or resorptive s...

AIM To determine baseline data in relation to procedures undertaken during nitrous oxide inhalation sedation sessions within the Hospital Dental Service. STUDY DESIGN A prospective study. METHODS Data was collected over a twelve-month period for patients attending the Department of Paediatric Dentistry, Dundee Dental Hospital, Dundee, Scotland, for dental treatment using nitrous oxide inhal...
