Correction of anterior crossbite using composite inclined plane

The crossbite is one of the local abnormalities affecting single incisor, which necessitates an early and immediate treatment to prevent short or chronic disorder. The purpose of this study was to evaluate a new functional approach to correct anterior crossbite of one incisor. A total of 18 children, aged 7 to 10 years, presented with simple anterior crossbite, were enrolled after clinical radiographic examination. All subjects received the same treatment which consists of a composite inclined plane directly bonded to the malposed maxillary incisor. Correction of anterior crossbite has been successfully achieved in all cases, and the treatment period ranged from one to two weeks. The proposed design is considered an easy approach, comfortable, esthetic and provides short treatment time. Accordingly, the reversed composite inclined plane could be used as an alternative design for interception of this problem especially during mixed dentition stage

Prosthodontic rehabilitation of oligodontia

Seven children [their age ranged from 8-12 years] complaining from partialanodontia and/or delayed eruption of teeth were included in this work. Acrylic resin partial dentures were constructed for each child and anyorofacial changes were evaluated. Most dentures required to be replaced orchanged. Cephalometric X-ray were performed for each child [before and afterwearing dentures] to evaluate any change in facial height. The evaluationrevealed increase in lower facial height of five children, while the other 2children showed no dimensional changes. A follow up period for 3 years,showed that acrylic resin partial dentures were extremely valuable aids in thetreatment of young children with partial anodontia

Detection of demineralization in occlusal fissures using the electronic caries detector: clinical and histological study

Ideally, sealant is placed over caries-free pits and fissures, although evidence supports the view that sealing will lead to the arrest of early lesion. However, clinical examination of a pit or a fissure will often leave doubt as to its caries status. The present study compared the validity of three in-vivo methods of caries detection with the histological appearance of the sectioned teeth. A total of 48 sound teeth, planned to be extracted as part of arthodonctic treatment were included in the study. Teeth examined to score stains in the fissures, bitewing radiographs were taken, fissures were also examined by vanguard machine. Following extraction, teeth were examined histologically and photographed using polarized light. The results found no consistent pattern to correlate stain in the fissures with vanguard readings or with histological examinations. Radiographs were of limited value in diagnosis of occlusal caries and would not be indicated for clinical diagnosis. A sensitivity of 76% of the teeth showing histological signs of dimineralization gave positive vanguard readings. As for specificity, 90% of teeth on which no demineralization was found histologically gave zero vanguard reading
