Aim: The aim of the presented study was to establish whether we can find differences in facial soft tissues morphology in patients with cleft palate compared to normal population using 3D facial scan, and to present a non-invasive examination method of 3D morphometrics. Material and method: The sample of patients included 22 men and 26 women. The most frequent in the patients was cleft hard and soft palate (83%), followed by submucous cleft palate (15%), and cleft soft palate (2%). The age of patients was within the interval 8 years and 1 months and 13 years and 11 months. The sample was subdivided into three groups according to the age. Measurements were performed with optical scanner 3dMDface System. The shape of cleft patient’s face was compared with physiologically average face of the controls of the given age and sex with SD score. Deviations between the scans were visualized with colour score in each patient. Results: In most patients the extent of cleft defect correlates with the extent of morphological changes of facial soft tissues. The mean deviation comparing facial maps of patients with cleft palate and the control group is 1.5 (SD). Conclusion: The results suggest that changes in facial soft tissues in patients with cleft palate are expressed.

OBJECTIVE: The subject of this case report is the application of a newly developed workflow for objective shade communication sans visual shade assessment or the use of shade guides. CLINICAL CONSIDERATIONS: Clinical complications stemming from issues relating to esthetic integration can present a burden on the restorative team, often resulting in strenuous relationships among its members. The faithful imitation of the optical appearance of dental hard tissues with direct- and indirect restorations has been at the center of interest in a great number of publications from the realm of esthetic dentistry over the past 40 years. The present report describes a new approach to objective shade communication, by transcending the role of dental photography from its purely descriptive purpose to the level of quantification, thus abandoning the use of the established shading regimes and replacing them with a patient personal shade recipe based on the CIELAB color space instead. CONCLUSIONS: Objective shade communication is possible with the eLAB system by combining numeric shade quantification with dental photography. CLINICAL SIGNIFICANCE: The eLAB system presents a viable alternative to the traditional approach to shade communication and shade matching in dentistry.

BACKGROUND: The EUROCRAN index has been used in inter-center studies to assess dental arch relationship (DAR) and palatal morphology (PM) in children with unilateral cleft lip and palate (UCLP). For this type of inter-center research, a scoring method that could be performed over the internet would be the most effective. Therefore, the aim of this study was to investigate the reliability of application of the EUROCRAN index on 3D digital models or photographs of plaster models instead of using plaster models. METHODS: The EUROCRAN reference models were presented in three formats: plaster models, 2D photographs of plaster models, and 3D digital models. Plaster models of children with UCLP (n = 45) were rated. Of each case, all three formats were rated by six calibrated observers in random order. The strength of agreement of the ratings was assessed with kappa statistics. Concordance among observers was evaluated with the intra-class correlation coefficient (ICC). RESULTS: The ICC showed a good inter-observer agreement for the DAR and poor inter-observer agreement for the PM. Intra-observer agreement for the DAR was moderate to very good, yet for the PM poor to moderate. Comparison between the three formats per observer for the DAR was good or very good and for the PM moderate to poor. CONCLUSIONS: The overall results show that the EUROCRAN index is an acceptable and reliable scoring method for the DAR on plaster models, 2D photographs of plaster models, and 3D digital models. However, due to the small range of deviations in palatal morphology between the cases in our study, the PM component of the index was difficult to assess. CLINICAL RELEVANCE: In clinical audits and inter-center studies, plaster models can be substituted by 2D photographs of plaster casts or 3D digital models when grading treatment outcome with the EUROCRAN index.

Dens invaginatus neboli dens in dente je méně častou vývojovou poruchou zubních tkání nejasného původu, postihující nejčastěji horní laterální řezák. Rozsah postižení vykazuje širokou variabilitu. Často vyústí v nekrózu zubní dřeně či atypickou chronickou periodontitidu. Anomálie zůstává i v současné době estetickým a léčebným problémem. V kazuistice je popsáno pozorování této anomálie subtypu 3A v klasifikaci podle Oehlerse u mladého jedince, řešené extrakcí zubu a jeho bezprostřední náhradou adhezivním fixním můstkem z kompozitního materiálu.
Dens invaginatus or tooth within the tooth is less common developmental anomaly of dental tissue of unknown origin affecting predominantly upper lateral incisors. The extent of the lesion reveals broad variability. It often results in the pulp necrosis or an atypical chronic periodontitis. The anomaly represents aesthetic and therapeutic problems even at present. This report deals with a typical lesion of the 3A subtype according to Oehlers´ classification in a young individual, treated by the tooth removal and its immediate replacement by the composite adhesive fixed bridge.
