Comments on "Dental lessons from past to present: Ultrastructure and composition of teeth from plesiosaurs, dinosaurs, extinct and recent sharks" by …
2016
The paper mentioned in the title suggests that several groups of extinct vertebrates used fluoroapatite as a tooth mineral in dentine and enamel when alive; its authors posit that this tooth mineralization drastically changed in all these lineages at some point during their evolution, leading to the use of hydroxyapatite as an alternative primary tooth mineral, because of hitherto unconsidered environmental changes. These conclusions are based on their finding high fluoride levels (i.e. fluoroapatite) in the dentine of fossilised shark teeth as well as in both the dentine and enamel of plesiosaurs, mosasaurs, and dinosaurs, which is in sharp contrast to recent teeth (which contain almost no…
Caries treatment in a four-year-old boy using hypnosis - a case report.
2021
This clinical case report demonstrates the successful application of hypnosis in an anxious four-year-old boy in whom two primary molars were treated with a composite filling. The almost 16-minute pediatric dental treatment was performed without complications and without interruptions. It could be shown that hypnosis can be used for the pediatric dental treatment of decayed primary tooth lesions. In the specific individual case hypnosis was not only used adjuvant but as an alternative to local anesthesia. A dental anxiety reducing effect and an elimination of pain perception were observed, so that the treatment was possible without anesthesia. It was also found that the communication and ra…
Radicular cyst in a primary molar following pulp therapy with gutta percha : a case report and literature review
2019
A radicular cyst (RC) in deciduous dentition is relatively rare. This clinical report presents a case of RC that condition derived from a primary molar undergone an endodontic treatment with gutta-percha approximately one year ago. In addition, we also considered whether intracanal medicaments and gutta-percha filling material related to the formation and development of the cyst or not. Key words:Primary tooth, radicular cyst, pulp therapy, gutta-percha filling material, intracanal medicament.
Effect of application time and concentration of silver diamine fluoride on the enamel remineralization
2021
Background Silver diamine fluoride has attracted attention because of its clinical success in arresting dental caries. Thus, the aim of this study was to evaluate the effect of different application times and concentrations of silver diamine fluoride (SDF) on deciduous tooth enamel remineralization. Material and Methods Blocks of deciduous tooth enamel were categorized into six groups of 11 each: 2 control groups: intact enamel, and demineralized enamel; 38% SDF and 30% SDF which were subdivided according to application times (1 and 3 min). The microhardness of samples was determined, and all groups except the intact enamel group were subjected to pH cycling to produce initial carious lesio…
