Abstract—A hypodermic needle embedded in the tissues for more than 20 years and associated with persistent pain was removed by dissection. It was found to have a fibrous capsule, was corroded and fractured readily during removal. Histological examination of the capsule showed no inflammatory reactio

摘要:

Abstract—Natural background radiation and man‐made radiations contribute to the individual and population radiation risks. These are discussed together with the recommendations for population protection. The contribution of dental radiography to these risks is small. The sources of unnecessarily high radiation in dental radiography are discussed. High quality diagnostic X‐rays are an essential part of high quality dental service — these can readily be obtained with minimum radiation exposure to the patient. The important factors to be considered include rectangular collimation of the X

摘要:

Abstract—Changes in methods of operating, in the use of effective methods of sedation, and extension in life expectancy have necessitated revision in local anaesthetic techniques. Modern anaesthetic agents and vaso‐constrictors are evaluated, dosage and methods of injection described. A careful evaluation of the patient together with the recording of an appropriate history is emphasi

Abstract—Penetration of a solution of 1131was observedin vitroin the apical zone of root canals of human teeth filled with zinc oxide eugenol, Rickert's root sealer and Alpha canal paste. With thicker mixes generally less penetration using lateral condensation compared with the thick mix and single cone or fluid mix and lateral condensatio

Abstract—Records for 1959–1969 from a children's hospital show that falls, play and motor vehicles are equally and mainly responsible for facial fractures in children up to 14 years of age. Methods of treatment and the effect of pre‐existing medical disorders on treatment are given and the necessity for complete history and examination at the time of admission is empha
