Radiogeometric evaluation of the dentofacial changes and their relationship to the temromandibular joint and dentition after adenoidectomy in children

The present study was conducted on sixteen children with age ranging from 6-12 years to evaluate the dentofacial changes and its relationship to the tempromandibular joint and dentition before and after adenoidectomy. Hence, this study was performed by using lateral cephalometry with a special constructed computer program in order to assess the skeletal angular, linear and dental measurements. Also, using scanora multimodal system and special geometric method in order to assess condylar position and condylar displacement, Children were divided into two groups, group 1 contained 8 children which suffered from adenoids [this group subdivided into group 1a before adenoidectomy and group 1b after adenoidectomy by 1 year] and group 2 contained 8 normal children. From our study it can conclude that the cephalometric radiograph is a valuable in diagnosis and treatment of skeletal deformities. Also, scanora multimodal system is a useful diagnostic images of high quality and sharpness rendering with any geometric method measurements more precise

Clinical comparison of two designs of cavity preparation with composite resin for class ii: slot preparation versus dovetail preparation in primary molars

This study compares the clinical characteristic evaluations of slot against dovetail. Class II com-posite restoration in primary molars of children aged 2 years 6 months to 5 years 3 months with the mean age of 4 years, one hundred and eight pairs of primary molars of class II of slot and dovetail preparations were made, then were evaluated for marginal adaptation, anatomic form, secondary caries and marginal discoloration after 6, 12 and 24 months, the results showed no statistical significance difference in the clinical characteristics between the two designs [p>0.05] although class II slot composite restoration showed a tendency toward better clinical characteristics with less failure

Evaluation of the effectiveness of the use of chlorhexidine oral gel 1% on the gingival condition of pediatric dental patients with fixed orthodontic appliances using oratest technique

Epidemiologic studies have demonstrated a close relationship between malocclusion, oral hygiene condition and the frequency and severity of periodontal diseases. Patients who wear fixed or thodontic appliances, become under a great risk to develop sever gingivitis .So during orthodontic treatment with fixed appliances, oral hygiene measures should be stressed particularly with children, also hygienic aids in addition to mechanical tooth cleaning should be prescribed. Hygienic aids such as tooth paste containing chlorhexidine can be effective. Rosenberg and coworkers reported a simple non-invasive technique named Oratest to estimate oral microbial levels, based on the rate of oxygen depletion in expectorated milk samples. This study was conducted on 33 patients with ages ranging from 8.6 to 15.3 years with mean 12 years suffering from periodontitis during fixed orthodontic treatment . we aimed to evaluate the effectiveness of chlorhexidine oral gel 1% on the gin-t-r-gival conditional of pediatric dental patients with fixed orthodontic appliances as well as the sensitivity of Oratest technique as a simple indicator for the gingival condition
