Coconut milk may not be suitable as an interim transport media due to poor maintenance of cell viability. However, probiotic milk was able to maintain PDL cell viability as well as HBSS.

Abstract:Other than in patients suffering from epilepsy, tongue lacerations are rare. Most commonly, these injuries occur when the tongue is between the teeth and a fall or blow occurs. They cause parents to panic and the child to cry uncontrollably with blood, tooth and soft tissue debris in the mouth. The presenting characteristics of the patient and injury as well as the treatment rendered and its outcomes are described.

Children are uniquely susceptible to cranio facial trauma because of their greater cranial mass to body ratio. Below the age of 5, the incidence of pediatric facial fractures in relation to the total is very low ranging from 0.6-1.2%. Maxillo-facial injuries may be quite dramatic causing parents to panic and the child to cry uncontrollably with blood, tooth and soft tissue debris in the mouth. The facial disfigurement caused by trauma can have a deep psychological impact on the tender minds of young children and their parents. This case report documents the trauma and follow up care of a 4-year-old patient with maxillofacial injuries.

Aim: The purpose of this study was to compare the residual dentin thickness after manual and rotary instrumentation technique in primary root canals using CBCT. The null hypothesis was that there is no difference in the cleaning efficiency of both manual and rotary technique. Methodology: Manual filing was performed on 30 root canals using stainless steel S-files. Rotary instrumentation was carried out on a further 30 root canals, using rotary ProTaper files in a 300-rotation per minute (r.p.m.) Handpiece (NSK Endomate DT) according to the manufacturer’s instructions. The roots were aligned perpendicularly to the beam, and they were scanned before and after instrumentation by using the CBCT operating at 60 kV and 2.5mA. Pre-instrumentation and post-instrumentation measurements of canals were performed by using the Carestream 3D software. Results: When both the manual and rotary methods of canal instrumentation were compared, it was found that the reduction of dentinal thickness with respect to the manual method was more than the rotary method. Conclusions: There was more dentine thickness reduction in manual instrumentation than rotary instrumentation for root canal preparation in primary teeth.
