Having knowledge of the cytotoxicity of various sealers will help in increasing patient's comfort.

Cracked tooth syndrome (CTS) is both a transient and progressive condition. There are numerous factors that may predispose a tooth to varying degrees of a crack. Incompletely fractured teeth are capable of causing great discomfort to the patient and it is also a source of concern for the dental practitioner. Diagnosis of CTS can be difficult. The patient reports with pain, and often the dentist relies on a periapical radiograph to determine the origin of the pain. Because CTS is a vital pulp condition, the periapical radiograph is of limited value as a diagnostic test. As a result, lack of treatment, or inappropriate treatment, will not resolve the symptoms, and the condition can result in the eventual loss of the affected tooth. This article will present the epidemiology, classification, etiology, signs and symptoms, the accurate diagnosis modalities and treatment options, along with prognosis and future prospects for this clinical condition through the undertaking of a comprehensive literature review of contemporarily available data.Through a comprehensive literature review, this article aims to provide an overview of the epidemiology, classification, etiology, signs and symptoms, diagnosis, treatment and prognosis, as well as future prospects of cracked teeth which may be a diagnostic challenge in clinical practice.

Aim:The aim of this study is to evaluate and compare the coronal discoloration induced by two Triple antibiotic paste (TAP 1 and 2), when used with varying depths of 2 and 4 mm of temporary sealing materials at the end of 0, 3, and 6 weeks.Objectives:(1) To evaluate coronal discoloration induced by TAP-1 when the depth of the temporary restorative material is 2 mm below cementoenamel junction at the end of 0, 3, and 6 weeks.Materials and Methods:Forty extracted permanent maxillary central and lateral incisors or single-rooted tooth were collected and chosen for the study. They were then divided into two groups and each group was then subdivided into two subgroups.Results:Both the triple antibiotic paste showed discoloration but it reduced with increase in thickness of temporary cement.Conclusion:TAP 1 and TAP 2 both showed an increase in discoloration, greater discoloration was seen with TAP, containing minocycline. There was a steady change in the discoloration from 0 to 6th week. In both the groups, TAP 1 and TAP 2, there was a reduction in discoloration with increase thickness of the temporary restorative material.
