Aim: Evaluate the clinical manifestations of craniosynostosis, imaging and surgical treatment with their complications. Materials and Methods: The study comprised twenty one patients complaining from craniofacial deformity. The patients evaluated by recording the medical history, clinical examination and diagnosed by imaging that included a plain X-ray and computed tomography. The goal of surgery is to open the fused sutures, reshape the head and allow for normal brain and skull growth. According to the type of material that used to fixate the cranial bones, the patients divided into 3 groups, Group A: Titanium plate and stainless steel wire; Group B: Stainless wire; Group C: Absorbable suture. Results: The clinical examination showed cranial bones deformity in all patients while 4 patients involved by papilloedema. The plain X-ray for the skull diagnosed 4 cases by showed beaten copper appearance, while the computed tomography gave excellent evaluation for all cases. The nonsyndromic craniosynostosis formed (90.4%) and coronal suture involvement formed (61.9%). The follow-up showed that the group C had more cosmetic improvement and more comfortable than group A and B, and there were 4 patients in group A and 2 patients in group B complained from extracranial prominent of plates and wire. Discussion: The advantages of absorbable suture included lower costs, speed of application, and absence of translocation. Conclusion: The most clinical manifestations were cranial deformity while visual deterioration was often late manifestations. The computed tomography scan represents the gold standard evaluation for craniosynostosis. The use absorbable suture in bone fixation showed more cosmetic improvement and more comfortable to the patients with low complication rate. *Corresponding author: Israa Anwar Abd al-Hameed, BDS, MSc Department of Periodontology, School Dentistry College, Mosul University Mosul, Iraq E-mail: amertaqa@hotmail.com Citation: Abd al-Hameed IA, Taha YA, Mahmood AS.

Among them, R. aeria can cause severe systemic infection diseases (e.g., bronchitis, endocarditis, pneumonia, and sepsis). However, the veritable prevalence of this organism in the human oral cavity has not ever been known. Thus, the selective medium for the isolation and quantification of R. aeria is necessary to assess the prevalence of this organism, and to diagnose various R. aeria infection diseases. To investigate R. aeria distribution in oral cavities, a novel selective medium (RAESM) was developed for isolating and quantifying R. aeria. RAESM consists of sodium gluconate, tryptone, meat extract, sodium fluoride, acriflavin neutral, fosfomycin, lincomycin, colistin, aztreonam, and agar. Polymerase chain reaction (PCR) primers were designed based on partial sequences of the 16S rDNA genes of R. aeria. The percentage of R. aeria in saliva samples collected from 20 subjects was examined. Moreover, we examined the antibiotic susceptibility of thirty isolates from six subjects. The average growth recovery of R. aeria on RAESM was 96.6% compared with that on Brain Heart Infusion supplemented with Yeast Extract (BHI-Y) agar. Growth of other representative oral bacteria, including other Rothia species, was remarkably inhibited on the selective medium. The PCR primers reacted to R. aeria and did not react to other Rothia species or representative oral bacteria. R. aeria was detected as 1.0% of the total bacteria, 5.9×107CFU/ml, on BHI-Y agar in the oral cavities of all subjects. R. aeria isolates obtained in this study were susceptible to most antibiotics; however R. aeria isolates from one subject were highly resistant to erythromycin, lincomycin, and clindamycin. R. aeria may be a part of the normal flora in the human oral cavities. A novel selective medium, RAESM, was useful for isolating R. aeria. Moreover, it was indicated that RAESM was useful for diagnosing R. aeria infections.","PeriodicalId":93308,"journal":{"name":"Journal of dentistry and dental medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49281870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: 120 synthetic intermaxillary elastics were divided into four groups according to different trademarks and type of manipulation.

The cultures were analyzed by visual inspection and when the culture medium presented turbidity, the presence of contamination was considered. Findings/results: Bacterial contamination was only found in the groups that occurred hand manipulation of the materials.
