This article presents the complex case study of an ancient skeleton presenting a maxillary supernumerary tooth (mesiodens). The skeleton was found in an archaeological site in the western part of Romania and was dated back to the Eneolithic period, some 5500 years ago. The aim of this article is to analyze the mesiodens and the jaws in light of current knowledge regarding anomalies of dental development of past and present-time populations. The cranial remains were investigated from an orthodontic perspective through inspection and cone beam computed tomography (CBCT) scan. The occlusion was analyzed according to Angle’s classification and observations were made regarding the presence of calculus, dental wear, presence of caries, bone loss and ante-mortem tooth loss. Observations were made regarding tooth dimensions and comparisons were made with modern population. In this specific case, the mesiodens caused minimum disruption within the upper dental arch and the occlusion. Additionally, it did not have any negative impact on the adjacent teeth or cause any other complication. Judging by the analysis of the jaws, the presence of the mesiodens had little impact on the overall oral health of the person. As suggested by other findings in the scientific literature, the mesiodens is an anomaly found throughout all historical periods, from the oldest archaeological sites to present day.

Unmanned aerial vehicles are currently the most used solution for cultural heritage in the field of close range and low altitude acquisitions. This work shows data acquired by multitemporal and multispectral aerial surveys in the archaeological site of San Vincenzo al Volturno (Molise, Italy). The site is one of the most important medieval archaeological sites in the world. It is a monastic settlement that was particularly rich during the early Middle Ages, and is famous for its two full-frescoed crypts which represent a milestone in the history of medieval art. Thanks to the use of multispectral aerial photography at different times of the year, an area not accessible to archaeological excavation has been investigated. To avoid redundancy of information and reduce the number of data to be analysed, a method based on spectral and radiometric enhancement techniques combined with a selective principal component analysis was used for the identification of useful information. The combination of already published archaeological data and new remote sensing discoveries, has allowed to better define the situation of the abbey during the building phases of the 8th/9th century and 11th century, confirming and adding new data to the assumptions made by archaeologists.

Aim. In this study, the authors set out to find the correlation between the data of cone beam computed tomography (CBCT) and the levels of inflammatory markers in patients with chronic generalised periodontitis (CGP), both without somatic pathology and with bronchiectasis.Materials and methods. The study included 90 CGP patients and 40 somatically healthy individuals with intact periodontium. CGP patients were divided into two groups: CGP patients without somatic pathology (n = 40) and CGP patients with bronchiectasis (n = 50). Using ELISA, the authors determined the level of the following inflammatory markers in oral fluid: transforming growth factor beta 1 (Tgfß-1), interleukin -8 (IL-8), lactoferrin (LF) and C-reactive protein (CRP).Results. The analysis of CBCT data and the levels of inflammatory markers (Tgfß-1, LF, IL-8 and CRP) revealed that more pronounced changes in their values were observed in CGP patients with bronchiectasis. In addition, the revealed correlations between CBCT data and the levels of inflammatory markers in CGP patients without somatic pathology and CGP patients with bronchiectasis indicate a relation between the severity of inflammatory reaction and the clinical manifestations of CGP. Furthermore, this correlation is stronger in CGP patients with comorbid pathology than in CGP patients without somatic pathology.Conclusion. The presence of comorbid pathology in the form of bronchiectasis in CGP patients has a negative impact on the periodontium, which should be considered when managing patients.

Abstract Dental cone beam CT (CBCT) scans, due to their low radiation dose, are now widely used in the medical diagnosis of patients’ oral cavity. The reconstruction of a panoramic view of the dental arch from the scanned CBCT data facilitates the dentist’s observation of the patient’s oral condition. The most important technique for reconstructing the dental arch panorama is the extraction of the dental arch curve accurately. The existing method is to rely on the experience of the dentist to manually connect the dental arch curve, or use techniques related to threshold segmentation to extract dental arch curve. These methods rely on the experience of dentists on the one hand. On the other hand, when there are interferences such as implants, metal tubes, braces or missing teeth in the patient’s mouth, the threshold calculation will be wrong. Based on this, this article starts with the histogram of CBCT data, and proposes a highly robust and fully automatic dental arch curve extraction method. In the actual experiment, the dental arch curves of 40 different patients were extracted, and all the dental arch curves can be accurately and automatically extracted, thus verifying the effectiveness of the proposed algorithm.

<p><strong>Abstract.</strong> The preservation status of an underwater cultural site can be determined as the combination of two primary factors, namely the site physical integrity, which results from the past and present interaction of the site itself with the biological/chemical agents located in the surrounding environment, and the exposure of the site to human-related threats. Methods to survey underwater archaeological sites have evolved considerably in the last years in order to face the challenges and problems in archaeological prospection, documentation, monitoring, and data collection.</p><p>This paper presents a case-study of an archaeological documentation campaign addressed to study and monitor the preservation status of an underwater archaeological site by combining the quantitative measurements coming from optical and acoustic surveys with the study of biological colonization and bioerosion phenomena affecting ancient artefacts. In particular, we present the first results obtained in the survey and documentation campaign carried out during the spring – summer 2018 in the “Nymphaeum of Punta Epitaffio” located in the Marine Protected Area - Underwater Park of Baiae (Naples).</p>

This chapter researches the possibilities for the sustainability of cultural heritage in inland territories, focusing on the case study of two archaeological sites in Serbia. Two plans, the plan for the archaeological site of Gamzigrad-Romuliana and the plan for the archaeological site of Caričin grad (Justiniana Prima), were analyzed from the aspect of sustainable development. These plans were prepared in compliance with the principles of preservation, protection, revitalization, and use of immovable cultural property for the purposes of science, education, presentation to the public and tourism. The conflicts between cultural heritage protection and development of tourism were analyzed. As a result of the analysis, recommendations for the sustainability of cultural heritage in inland territories are given in the chapter.
