[Endodontics and apical periodontitis].

The aim of this paper is to discuss the relation between root canal treatment and apical periodontitis (AP). AP is caused by micro organisms and is mainly a chronic inflammation. There is some evidence of an effect on the general health in immunocompromised patients. A higher incidence of AP on root filled teeth has been found. A number of preoperative and operative factors influence prevalence of AP on root filled teeth. Rubberdam placement and cleaning and shaping of the root canal during root canal treatment is important to create a clean canal to promote healing or prevent the development of AP. Placement of a good quality root filling and a well sealing coronal restoration are also important for the prevention of reinfection of the root canal. The quality of root fillings differs between clinical and epidemiological studies what is reflected in a lower prevalence of AP in the former.

[Fraudulent use of digital radiographs: secret reality or fiction?].

Digital radiography has several advantages and has become an indispensable diagnostic tool for many dentists in daily practice. Once the digital captation appears on screen, the dental x-ray software allows image enhancement, to get a better vision and diagnosis. This image enhancement is acquired for example by adjusting the colour, density, sharpness, brightness or contrast. If the digital radiographs are exported, using various software packages created for graphic design and image manipulation, digital information can be altered, added or removed. Dental radiographs are easily duplicated, stored or spread in digital format. How can their authenticity be guaranteed, especially in insurance cases? Image enhancement features of digital radiography allow mishandling or potential abuse. Recently published studies illustrate the potential fraudulent use of digital radiography. In this article, some manipulated radiographic images are presented, to raise concerns about security, reliability and the potential for fraud.

[Coronal leakage reconsidered].

The aim of the present study was to evaluate the impact of the quality of the coronal restoration and of the root filling on periapical health. In a sample of 937 root filled teeth which had not received restorative treatment in the previous year, the technical quality of the coronal restorations and of the root fillings was radiographically scored; in addition the technical quality of the coronal restorations was clinically scored as well. The data showed that the technical standard of both coronal restoration and root filling were essential to periapical health. The study also showed the relatively limited value of epidemiologic findings. Epidemiologic research is descriptive as well as analytical in approach. According to the present data, endodontic failure cannot be fully explained by radiographic analysis only. Nevertheless, epidemiologic data remain a valuable component to the source of knowledge regarding etiologic factors and proper treatment procedures in order to improve the results of endodontic practice.
