We aim to create an information platform by contributing orodental findings of Pompe disease to literature. An 18-month-old male patient with Pompe disease was referred to our clinic due to swelling of the gums. In first dental examination, a nonfluctuant, normal gingiva colored swelling at the right anterior region of maxilla was detected. His parents were recommended to perform finger massage to the region. Six months later, 51, 52, 62, and 74 numbered teeth had erupted, there was a fusion between 51 and 52 numbered teeth, 84 numbered tooth was seen to be erupted, and a swelling at the site of this tooth, similar to previous one, was present. Finger massage was recommended for this area as well, and the swelling was found to have decreased at the follow-up, one week later. Tooth eruption problems and developmental dental abnormalities should be included in the signs for Pompe disease.

OBJECTIVE: The aim of the study was to evaluate a group of Turkish dentists' attitudes and level of knowledge about teething gels. MATERIAL AND METHODS: For this cross-sectional study, a questionnaire consisting of three parts and twenty questions was sent to dentists (n=1829) whose contact information could be reached. Separate categories were created for ingredients, dosage, and side effects of each prescribed teething gel. The percentages of the knowledge level of the dentists were calculated considering all prescribed gels. RESULTS: A total of 484 dentists were included in the study. Approximately half of the dentists (51.2%) participating in the study reported that they prescribed at least one teething gel per month. The most commonly prescribed teething gels were lidocaine-based gels (70.9%), followed by hyaluronic acid-based (61.4%) and herbal-based gels (36%). The medians of the knowledge level of dentists about active ingredients, dosage, and side effects of teething gels were 50%, 25%, and 20%, respectively. Dentists with more years in the profession have more knowledge about the active ingredient and side effects of gels than those who are newer in the profession (p<0.05). Dentists with the aged between 20-30 years had more knowledge about the dosage of gels (p<0.05). It was found that the knowledge level of pediatric dentists and oral surgeons about the side effects of gels was higher than other branches. (p<0.05). The knowledge level about teething gels of non-specialist dentists was significantly lower than specialists (p<0.05). CONCLUSIONS: In conclusion, it was found that dentists had insufficient knowledge about teething gels. Dentists need more education to prevent misuse and uncontrolled use of these gels.

Objective: The aim of this in vitro study was to evaluate the efficacy of rotary EndoArt Ni-Ti Gold Pedo Kit and K-files in shaping ability, canal transportation, centering ability and instrumentation time in primary molars. Methods: For the study total of 30 extracted primary molars root with minimum 7mm root length were selected. Shaping of root canals in primary molars were done using the two systems, and CBCT and specialized software were used for scanning and analysis of pre-operative and post-operative to evaluate the groups for their shaping properties, apical transportation and preparation time in primary root canals. Results: No differences were found in canal transportation measures and instrumentation time between the two groups (p>0.05). The EndoArt group removed more dentin compared to K-file in all sides of the root curvature. The statistical differences were significant for coronal and middle third of the root (p<0.05). Conclusions: Under the conditions of this study, rotary EndoArt Ni-Ti Gold Pedo Kit provided more conical canals than K-files in primary teeth.

Background: Manual or mechanized instruments can be used for root canal preparation. Manual instrumentation using K-files is widely used in primary teeth, but there are many limitations. Mechanized root canal preparation can lead to easy access to all canals, decrease instrumentation time, and result in more funnel-shaped root canals, resulting in a more predictable uniform paste fill.Aim: This study aimed to evaluate the shaping ability and instrumentation time of VDW.ROTATE™ and EdgeTaper Platinum™ during the preparation of resinprinted primary molars. Hand K-files were used as a reference for comparison.Design: Sixty-six resin-based maxillary second primary molars, obtained from extracted tooth cone-beam computed tomography (CBCT) image and printed on a three-dimensional printer, were divided into three groups: VDW.ROTATE™, EdgeTaper Platinum™, and K-files. The specimens were scanned using CBCT imaging before and after root canal preparation. Images were registered using a dedicated software, and changes (Δ) in the canal area, volume, and untouched canal surface were calculated. Instrumentation time was evaluated. Data were statistically analyzed using the SPSS program.Results: There was no significant difference among the tested file systems for Δ canal volume and area (p > .05). VDW.ROTATE™, however, showed significantly lower untouched canal surface area than other systems in all roots (p < .001).The VDW.ROTATE™ was found to be significantly faster (6.47 ± 0.39 min) than EdgeTaper Platinum™ (7.71 ± 0.73 min) and K-files (8.22 ± 0.72 min), (p < .05). Conclusions:The shaping ability and the instrumentation time were directly influenced by the root canal instrumentation system used during the preparation of resin-printed primary molars, with VDW.ROTATE™ being the faster system and associated with the lower amount of untouched canal surface area.
