Periapical surgery

Image
 The objective of apical surgery is to surgically maintain a tooth that has an endodontic lesion which cannot be resolved by conventional endodontic (re-)treatment (von Arx 2005). The evaluation of a case referred for apical surgery must always include a careful weighing of the advantages and disadvantages of surgical and non-surgical intervention, i.e., the possibility of a conventional root-canal (re-) treatment should be considered as a therapeutic option In the present case surgery was done on lower anterior teeth.  Tissue reflection should begin from the vertical releasing incision at the junction of the submucosa and the attached gingiva. After the tissue is reflected, it must be retracted to provide adequate access for bone removal and root-end procedures. Removal of cortical bone to expose the root apex. currettage os done to remove cyst and lining.   The root has a darker, yellowish color and is hard, whereas the bone is white, soft, and bleeds when scrapped...

Light activated bleaching of discoloured non-vital tooth

Image
  Trauma and pulpal infections are part of the routine of the dental practice. Common consequences in these cases are alterations in dental color, compromising patient’s esthetics and his interaction in social environment. Bleaching aids to preserve dental structure as compared to full coverage crowns and also show immediate esthetic results. This clinical case shows a bleaching technique in devitalized teeth using bleaching agent with 35% hydrogen peroxide activated by LED light. The technique is simple to perform and also shows satisfactory results.             Informed consent was taken before treatment. On the onset of treatment, the shade of the discoloured tooth was assessed under normal daylight with a Vita porcelain shade guide (Vita classic) and also, a pre-bleaching photograph was taken for the record. On the first appointment 2mm of gutta-percha is removed from the canal orifice with a heated instrument and restored with GIC up to the c...

QUICK FIX for a fractured tooth

Image
                      Anterior teeth trauma is one of the most common dental injuries. The type of injury and the condition of the injured tooth often dictates the treatment required. Reattachment of tooth fragment is one such treatment option that has a shorter treatment time and provides good aesthetics and function with relative ease and lesser complications in a less invasive way. Reattachment of tooth fragment can be considered one of the first treatment options over complete replacement procedures owing to its simplicity and conservation of tooth structure but the patient’s cooperation is of utmost importance for such a procedure. It is important to explain the limitations of the treatment and expected outcome. The present case describes the management of fractured mandibular anterior teeth by endodontic therapy and fragment reattachment. The reattachment of fractured fragment helped establish good esthetics in a rel...

Mandibular molar with three distal canals: Its identification and management

Image
  Man dibular first molars are the first posterior teeth to erupt in permanent dentition and are those that most often suffer from caries. They are also the teeth that exhibit considerable anatomical variation and abnormalities regarding the number of roots and root canals. Therefore the clinician should know the various morphologic aberrations occurring in this tooth before starting the treatment. This case presents with mandibular first molars with 3 distal root canals and one root. The tooth was treated endodontically with the help of dental operating microscope. CASE 1: Local anaesthesia was induced using 1.8 ml of 2% Lignocaine and Adrenaline (Xylocaine; AstraZeneca Pharma Ind Ltd, Bangalore, India). The tooth was isolated using rubber dam and an endodontic access opening was established. The orifices of mesiobuccal, mesiolingual, distobuccal and distolingual were apparent and were initially located. The floor of the pulp chamber was viewed under dental operating microscope (...
