The current study was conducted to investigate the biological effect of commercial orthodontic mini-screw implants on the oral investing tissue. In accordance, a total sample of … orthodontic patients (… females,… males), had been selected at random from a group of total … orthodontic patients, using a random table method. Calculation of sample size was based on determination of the power of statistics of the study. The sample was selected from patients seeking orthodontic treatment in the Outpatient Clinic, Orthodontic Department, Faculty of Dental Medicine (Boys), Al-Azhar University, Cairo. Inclusion criteria: The patients were included in this study if they have the following: 1- All cases indicated for bilateral extraction of maxillary
In this study, children suffering from Congenital Heart Disease were 55%. Haemophilia or other coagulopathy, Insulin dependent diabetes and Epilepsy were 5 8%, 5% and 30 % respectively. Practitioners had treated very few children with malignancies (2%) [FIGURE 2]. The lack of familiarity regarding various medical conditions and pharmacological regimens is of concern and suggest the need for readily available specialist dental care for children requiring dental treatment. Medically compromised children who have high caries risk should have dental check-ups every 3-6 months even if they don’t have any problems concerning their teeth16.
At one of the international conferences on hypodontia an international agreement was announced about who should be on the team. The conclusion was that the members of the team should include the following: General dental practitioners, pediatric dentists, prosthodontists, orthodontists, oral and maxillofacial surgeons, dental nurses, clinical psychologists, clinical geneticists, dermatologists, specialist laboratory technicians, speech and language therapists.14 Numerous clinical reports have demonstrated the importance of prosthetic dental treatment in patients with hypodontia for physiological and psychological reasons. Treatment of hypodontia varies, and includes removable partial denture and fixed functional space maintainers. In this case fixed functional space maintainer is recommended. The rationale for use of fixed functional space maintainers is its esthetic appearance, easy care, acceptable cost, cooperation of the patient not needed and easy
Hosseini, MDM is a professor of clinical oral and maxillofacial surgery at Temple University School of Dentistry. His is involved in curriculum development, outcome assessment, and integration of technology in education. The chapter on dental implants in Darby and Walsh book discuss different types of dental implants and osseointegration of implants, diagnosis and dental hygiene care of peri-implantitis, and its management. In addition, it identifies several devices that can be used to clean dental implants, and professional armamentarium that used in office treatment. Finally, it defines failed implant.
Orthodontics is the branch of dentistry that corrects teeth and jaws that are positioned improperly. Crooked teeth and teeth that do not fit together correctly are harder to keep clean, are at risk of being lost early due to tooth decay and periodontal disease, and cause extra stress on the chewing muscles that can lead to headaches, TMJ syndrome and neck, shoulder and back pain. Teeth that are crooked or not in the right place can also detract from one 's appearance. The benefits of orthodontic treatment include a healthier mouth, a more pleasing appearance, and teeth that are more likely to last a lifetime. A specialist in this field is called an orthodontist.
Traumatic dental injuries are common, attention-seeking problems that affect children worldwide. It is of utmost importance to treat such injuries correctly and on time to improve future outcomes and avoid pulpal and periodontal damage in cases of permanent tooth injury. It is as important to manage TDI in primary teeth to avoid disruptions to the succedaneous permanent teeth. Dental trauma falls under four main categories according to Andreasen (Feliciano and de França Caldas Jr, 2006); injuries to the hard tissues and dental pulp, injuries to the periodontium, injuries to the supporting alveolar bone, and injuries to the oral mucosa. Injuries to the Hard Tissues and Dental Pulp Uncomplicated Crown Fracture: this can include either an
Most of conventional orthodontic treatments require more than one year to complete. Unfortunately many potential orthodontic patients jeopardize their dental health and decline treatment, due to this long treatment times. The development of corticotomy-assisted orthodontic treatment (CAOT) opened doors and offered solutions to many limitations in the orthodontic treatment of adults. It was first introduced in 1959 by Kole  as a mean for rapid tooth movement. It was believed that the main resistance to tooth movement was the cortical plates of bone and by disrupting its continuity, orthodon¬tics could be completed in much less time than normally expected.
Thorough history revealed trauma due to fall 1 year back , which resulted in the fracture of upper front tooth. The patient had visited the dentist for the treatment, but discontinued it in between. Clinical examination revealed a fracture (Ellis class IV #) and associated greyish black discoloration of the crown of tooth 21(Fig 1a) and the vitality test revealed 22 as non vital. An intraoral periapical radiograph revealed the presence of a radio-opaque object inside the root canal extruding periapically, approximately 4 mm from the apex with periapical radiolucency involving 21 and extending to the root of 22 (Fig 1b). After considering the clinical and radiographic findings, an attempt to retrieve the foreign object using H files and thereafter completing the root canal treatment nonsurgically was planned.
Consistent, reliable and practical detection and assessment of dental caries lesions as an effect of dental caries disease has been a challenge for a long time. The caries can be observed on all surfaces of the primary, permanent, and mixed dentitions. Surface lesions can then be calculated according to the type of the teeth (molars, premolars, incisors and canines) or according to the surfaces (proximal, occlusal and free smooth surfaces) (Burt., 1997; Ismail., 2004; Pitts., 2004). The lesions have to be assessed as to whether the caries is limited to enamel or if it has progressed to dentin. The activity of lesions need to be determined as cavitated lesions continue to trap bacterial plaque and need to be restored.
Research shows that ninety percent of people irrespective of the age and gender are suffering from dental problems. Various types of images are used in dentistry for correct diagnosis and treatment planning for example X-rays , dental radiographs, etc. The most common X-rays used are the intraoral, depending upon whether the X-ray film is inside or outside the mouth and are classified by either beitwing X-ray, periapical X-ray or panoramic X-rays. Beitwing X-rays have some advantages over the other imaging techniques as the lesions are more prominent in beitwing radiographs
