Abstract

Local anesthetics are the most commonly used drugs in dentistry. Despite preoperative patient evaluation, proper tissue preparation and meticulous administration techniques many local and systemic complications with the local anesthesia or tooth extraction have been reported from time to time. Extension of dental infections from maxillary teeth and other nearby structures to orbital spaces and tissues surrounding the eye present a rare but serious problem with the potential for causing significant impairment. The practioner should be aware of the severe consequences that may result from tooth extraction or local anesthesia.

Abstract

Aim: The aim of this study was to investigate the ischolar_main canal morphology of mandibular premolars in Northern region of India using a decalcification and clearing technique. Method: Three hundred extracted human mandibular premolars, collected from dental clinics within North India were selected for this study. Following pulp tissue removal, India ink was injected into the ischolar_main canals and the teeth were decalcified with 5% nitric acid, dehydrated with ascending concentrations of alcohol and rendered clear by immersion in methyl salicylate. Cleared teeth were examined under 5X magnification and the following features were evaluated: (i) number and type of ischolar_main canals; (ii) presence and location of lateral canals and; (iii) location of apical foramina. Results: 84.2% of the specimens exhibited Type I canal pattern. Type VIII was not observed in any of the specimens. The lateral canals were in the apical third in 78.7% of the specimens followed by middle third in 16.5% and the cervical third in 4.7%. 82.7% of the specimens showed lateral position of the apical foramen. Conclusion: Mandibular premolar teeth present a wide variety of radicular features, with one ischolar_main and one canal being found in majority of the cases. An accurate knowlegde of the morphology of the ischolar_main canal is essential for proper diagnosis and successful treatment of endodontic cases.

Abstract

Dentoalveolar surgery is accompanied by a number of complications, one of these is bleeding. The majority of patients who bleed after extractions do not have any underlying haematological disorders and generally have had extractions previously without complications, suggesting a purely local factor in the occurrence of haemorrhage; e.g., local infection, traumatic surgery and noncompliance to postoperative instructions. Here we report a case of 14 year old female patient who reported to our department for ortho extraction and after atraumatic tooth extraction the blood continued to ooze for hours. All the local measures failed to control the oozing. Dengue has become a global problem since the second world war. No antiviral drugs or vaccine has been invented so far. The range of the disease appears to be expanding possibly due to climate change.
