Evaluation of caries in deciduous second molar and adjacent permanent molar in mixed dentition

Comparison of the crown dimensions between the maxillary second deciduous molar and the first permanent molar.

The morphologic relationship of the crown structures of the maxillary second deciduous molar (m2) and the first permanent molar (M1) was investigated with odontometric methods. Materials used were 124 male dental casts taken from Chinese living in Kaohsiung (Taiwan). The mesiodistal and buccolingual diameters, cusp sizes, and intercusp distances were measured. The mean crown diameters were larg...

Black Stain and Caries in Deciduous and Mixed Dentition

Mandibular Second Molar Periodontal Parameters after Surgical Extraction of Adjacent Impacted Third Molar

Introdouction: Impacted mandibular third molar surgery may affect periodontal status of the adjacent second molar. The purpose of this study was to evaluate the changes in periodontal health parameters distal to the adjacent second molar following surgical extraction of an impacted mandibular third molar. Materials and methods: We selected 50 subjects with a mean age of 22.8 (ranging from 18...

Distalization of Maxillary First Permanent Molar by Pendulum Appliance in Mixed Dentition Period

Introduction Mesial drifting of molar teeth in maxillary arch is corrected by movement of the molars distally. In addition to traditional distal movement techniques, such as extraoral force application and removable appliances, various intra-arch devices have been introduced since 1980s. These intra-arch appliances have nearly eliminated the need for patient cooperation. Case report The purpo...

Pendulum Therapy of Molar Distalization in Mixed Dentition

Early and timely pedo-orthodontic treatment is aimed at eliminating the disturbances of skeletal or dentoalveolar development, to harmonize the stomatognathic system before the full eruption of all permanent teeth. The advantages of pendulum appliance are its minimal dependence on patient's compliance (child cooperation), ease of fabrication, onetime activation and adjustment of the springs if ...
