The Management of Crown Fracture of Immature Teeth by MTA and Calcium Hydroxide

Traumatic injuries to teeth with or without pulpal involvement occur in children and adolescents. The majority of these injuries occur before root formation is complete, causing in some cases pulp inflammation and necrosis, with possible impact on the quality of life of affected individuals. Anterior crown fractures are favoured by the protruded position of maxillary incisors and their eruptive pattern. The most susceptible age to dental trauma is between 6 to 12 years . Complicated crown fractures represent 18-20% of all traumatic injuries topermanent teeth. 
Crown Fracture of Immature Teeth by MTA

The treatment options vary due to tooth maturity, the time lapse between the accident and the treatment, the severity of pulp exposure, the presence or absence of haemorrhage, the size of the remaining crown, periodontal status and occlusal relations . Root formation is classified in seven stages by Moorrees et al. Vital amputation (pulpotomy) is the treatment of choice for traumatized immature teeth with pulp exposure. It allows further root development, with apical closure and strengthening of the root structure. If the pulp vitality of a traumatized immature tooth is lost, the treatment will be a challenge, especially for pulp necrosis in teeth with inadequate radicular development due to the fact that an open apex in permanent tooth takes approximately 3 years to close after tooth eruption . In the case of pulp necrosis, pulpectomy and root canal therapy should be preferred. Read more.............

Harvesting Free Palatal Masticatory Mucosal Graft Using 3a Mucotome

Image
The technique of free autogenous gingival grafting (FGG) has undergone little modification since its introduction by Bjorn in Scandinavia in 1963 and by King and Pennel inthe United States in 1964. The technique is widely used to treat a variety of mucogingival problems such as insufficient or lack of attached gingiva, the presence of high frenum attachments, shallow fornix and denuded roots following gingival recession.  FGG can be procured from donor site using scalpels, gingivectomy knife or palatal shaving knife (Paquette knife). The donor site is frequently the palate, although the use of edentulous ridge areas, tuberosity and attached gingiva has also been described. Scalpel is most commonly used and conventional method for procuring gingival auto grafts. Gingivectomy knife, although not commonly used, also works on similar principle. Since the scalpel blade is straight and stiff and the palate is curved, repeated incisions to release the graft from underlying conn...

Indications for Orthognathic Surgery

Image
Orthognathic surgery (OS) is a surgical intervention that alters relationships of the jaws and dental arches. The treatment involves a combination of orthodontics and maxillofacial surgery.  Orthognathic Surgery It is used to correct dentofacial deformities that cannot be treated with acceptable results by conventional orthodontics. The first description of a surgical intervention to correct a malocclusion was by Hullihen in 1849. The most frequently used surgical procedures for correcting the relationship of the jaws are Le Fort I osteotomy and sagittal ramus split osteotomy. Also often used are vertical ramus osteotomy, inverted L osteotomy, and variations and combinations of the above. Read More>>>>>>

Dental Ailments may be risky for Cardiac Patients

Image
Patients that are suffering from cardiac t=disorders are susceptible to physical and mental stress. Dental ailments add to the stress further as these patients are unable to cope with the pain due to cardiac disorders. These patients may encounter medical emergencies in case of dental disorders and they may demand multi disciplinary approach to achieve the success. Additionally, the results of cardiac surgery may suffer if the oral cavity is not maintained well since there is always a fear of infection affecting the heart from the oral cavity. Hence, the cardiac surgeon has to refer surgical patients to a dentist for oral prophylaxis and to treat any oral infections before cardiac surgery to prevent infective endocarditis. PDF LINK
