Conscious Inhalation Sedation with Nitrous Oxide and Oxygen in Children: A Retrospective Study
No full textDental anxiety is a common problem in younger children, especially those who have had traumatic or perceived traumatic dental treatments. Nitrous oxide (N2O) and oxygen (O2) have been recommended by the American Academy of Pediatric Dentistry as the optimal approach for uncooperative or anxious patients. The study aimed to evaluate the cooperation of children treated on deciduous teeth without local anesthesia and with rubber dam. A retrospective study was conducted from January 2019 to December 2020 in a private dental practice on children aged 4–10 years who had previously reported cases of dental anxiety during dental procedures or refused to undergo them. After an initial cognitive examination, the children underwent conservative treatment lasting a maximum of 30 min. Initially, 100% O2 was administered, then N2O dose was gradually increased to 35%. At the end of the treatment, 100% pure O2 was administered for 5 min. Children’s cooperation was assessed by Venham score before treatment (T0), at the end of induction (T1), and during the treatment (T2). A total of 371 children (age: 6.3 ± 1.7 years) were included in the study. Cooperation increased significantly from baseline at T1 (p < 0.001) and T2 (p < 0.001). Younger children (4–6 years) showed lower levels of cooperation at baseline (p < 0.001) but achieved optimal levels of cooperation at T1 (p = 0.022). Only 2.7% of children reported side effects. N2O/O2 proved to be an effective and safe method in achieving a good level of cooperation in younger children
Photobiomodulation to Reduce Orthodontic Treatment Time in Adults: A Historical Prospective Study
No full textBackground: Orthodontic treatment in adult patients is hindered by several problems, such as little time for regular dental visits and financial costs. In recent years, photobiomodulation (PBM) has been shown to significantly reduce the duration of orthodontic treatment and significantly increase patient compliance. Objective: This study aimed to investigate the efficacy of PBM in shortening the orthodontic treatment duration in adult patients while ensuring optimal patient compliance. Methods: A total of 170 orthodontic patients with a Little’s irregularity index (LII) ≥ 3 mm treated with Invisalign clear aligners (Align Technology, Santa Clara, CA, USA) were included. The treatment group (PBM) (n = 90 patients) was trained in the use of the OrthopulseTM device (Biolux Research, Vancouver, Canada) according to an application protocol of 5 min per day. The control group (n = 80 patients) was treated with transparent Invisalign® without PBM applications. The LII was measured at a baseline and each aligner change until the end of the treatment when the LII was less than 1 mm. The crowding resolution rate (CRR), expressed in mm/week, and the total treatment time were measured. Results: The alignment rate of the PBM group was significantly higher than that of the control group (0.33 mm/week vs. 0.21 mm/week) with a reduction in the treatment time of 57.5 weeks in the PBM group compared with the control group. Conclusion: The PBM performed with the Orthopulse™ is shown to be an effective and noninvasive technique for accelerating teeth movements and can contribute in a relevant way to increase access to orthodontic treatment by the adult population as well as increase its compliance

Study for a new definition of the southern side of Prato della Valle in Padua, Italy
No full textThe boundary wall of the Santa Maria della Misericordia convent continuously delimited the southern limit of the Prato della Valle space in the southern part of Padua’s historical centre. Its presence was one of the elements that more than two century ago inspired the enlightened proposal by Andrea Memmo, the Superintendent of the Republic of Venice, and Domenico Cerato, a design professor at the University of Padua. Subsequently the straight and continuous limit was replaced by the discontinuous architecture of the Foro Boario entrance, built in 1913 according to a design by Alessandro Peretti; this weakened the overall solution based on an elliptical shape and the communicative power of the nearby basilica of Santa Giustina. The examination here presented dwells on these limits, simulating the virtual introduction of architectures with a continuous front to the southern edge of the Prato della Valle. One example is the Nelson-Atkins Museum of Art built in Kansas City between 1930 and 1933, based on a design by the brothers Thomas and William Wight, and expanded in 1999 by Steven Hall. The study generally confirmed that the compactness of the building's front newly provides strength to the late 18th century Memmo’s creative intuition, which gave a sense of unity to the general emptiness thanks to the certainty of its borders, and gives again the Basilica of Santa Giustina its monumental size. This paper investigates the composition of heterogeneous fragments, excerpts from the inventory of collective memory, and the resulting unpredictable architecture in an urban context
