Abstract

<p><span>This article has no abstract. The first 100 words appear below:</span></p><p>A 33 year old male patient came to the outpatient Department complaining of the bad appearance of his upper left central incisor tooth. He had no history of trauma in that area but the tooth was discolored gradually (Figure 1A). Furthermore, the tooth was asymptomatic. There was no pain and discomfort during mastication. The patient had gastric irritation for the last 5 years and still using omeprazole irregularly. The clinical examination indicates that the left central incisor tooth was yellowish in color and the dentine was found to be exposed (Figure 1B). There was gross tooth tissue loss at the labial surface that includes the incisal edge of the tooth.</p>

“…[16][17] Furthermore, root canal obstructions including calcification is considered as one of the most causes of failure. 18,19 Calcification in the root canal system is also associated with various etiological factors include caries, trauma, drugs and aging. 20,21 In the present case, either chronic irritation due to deep caries close to the pulp chamber or the use of the restoration in the pulp chamber without pulpectomy might be the possible cause for calcification.…”

Internal Bleaching of a Non vital Anterior Tooth in Patient with Postural Hypotension

“…When we prioritize the minimally invasive, internal bleaching can offers simple conservative approach without damaging tooth structure. The process of indirect bleaching begins when its chemical process touches the tooth's surface 6,10,11 . Root filling or gutta percha should be lowered by 1-2 mm under the cement enamel junction (CEJ).…”

“…The shape of the barrier was kept as 'bobsled tunnel' when viewed from facial aspect. The advantages of this shape can block all the dentinal tubules which run from pulp chamber to external tooth surface apical to the level of epithelial attachment so that the bleaching agent stays within the cavity and hence prevents external root resorption 4,8,11 . Bleaching agents which contains oxidation agent are hydrogen peroxide, chlorin or natrium hypochlorite.…”
