Digital Workflow for Indirect Bonding with 2D Lingual Brackets: A Case Report and Procedure Description.

Case Rep Dent 2019 28;2019:6936049. Epub 2019 Apr 28.

Unit of Orthodontics and Paediatric Dentistry-Section of Dentistry-Department of Clinical, Surgical, Diagnostic and Paediatric Sciences, University of Pavia, Pavia, Italy.

Objective: During orthodontic therapy, accuracy in bonding procedures makes it easier to correct tooth alignment by decreasing the need for midcourse corrections by changing bracket positions. Indirect bonding allows the transfer of the appliance components from model casts to patient's teeth potentially meaning shorter appointments for bracket bonding and rebonding and best comfort during chairside practice. At the same time, there has been a steady increase in requests for invisible lingual orthodontic treatment.

Clinical Considerations: Accordingly, the aim of the present report is to illustrate the workflow to realize a complete digital indirect bonding for lingual brackets (2D, Forestadent). The procedure starts with intraoral digital scans, digital 3D model, and virtual bracket positioning, ending with the realization of a CAD-CAM prototyped transfer tray. A 3D intraoral scanner (True Definition, 3M) is used to create digital scans and digital models. A virtual bracket positioning is performed using software (NemoCast, Dentaurum), and a prototyped transfer tray is created by a CAD-CAM device. 2D lingual brackets were positioned inside the tray, so the appliance was bonded to the dental surface using light curing adhesive resin.

Conclusions: During orthodontic treatment, CAD/CAM technology could help clinicians. Computer-constructed transfer trays can reduce clinician error and improve the everyday workflow in the office.

Diode Laser-Assisted Surgical Therapy for Early Treatment of Oral Mucocele in a Newborn Patient: Case Report and Procedures Checklist.

Case Rep Dent 2018 24;2018:3048429. Epub 2018 Apr 24.

Unit of Orthodontics and Paediatric Dentistry, Section of Dentistry, Department of Clinical, Surgical, Diagnostic and Paediatric Sciences, University of Pavia, Pavia, Italy.

Mucocele (also known as ranula or salivary gland mucous cyst) of the newborn is a lesion present on the intraoral cavity, with the potential to interfere with respiration and feeding. In the present report, a case of mucocele in a 4-month female patient has been described. As conventional surgery can be followed by several complications such as intraoperative bleeding, difficulties in wound healing, and maintenance of sterility during surgery, in the present case, the use of diode laser has been planned. A topic anesthesia with lidocaine gel was performed. A diode laser (810 nm wavelength, continuous wave mode, power output of 3 watt, and 0.4 mm diameter fiber optic) was set for excising the lesion. The tip was directed at an angle of 10 to 15°, moving around the base of the lesion with a circular motion. The procedure was completed in 3 minutes. The patient was visited with a follow-up of 2 weeks and 4 months after excision. The intraoral wound healed without complications, and no signs of infection or mass recurrence were noted. The histopathological examination confirmed the diagnosis of mucocele. On the basis of the results of the present case report, the use of diode laser can be easily performed also in a noncompliant newborn patient for successful excision of mucocele lesions, and checklist of clinical procedures has been described.

Multicenter randomized, double-blind controlled trial to evaluate the efficacy of laser therapy for the treatment of severe oral mucositis induced by chemotherapy in children: laMPO RCT.

Pediatr Blood Cancer 2018 08 4;65(8):e27098. Epub 2018 May 4.

Pediatric Hemato-Oncology Unit, IRCCS materno infantile Burlo Garofolo, Trieste, Italy.

Objectives: To demonstrate the efficacy of laser photobiomodulation (PBM) compared to that of placebo on severe oral mucositis (OM) in pediatric oncology patients. The primary objective was the reduction of OM grade (World Health Organization [WHO] scale) 7 days after starting PBM. Secondary objectives were reduction of pain, analgesic consumption, and incidence of side effects.

Methods: One hundred and one children with WHO grade > 2 chemotherapy-induced OM were enrolled in eight Italian hospitals. Patients were randomized to either PBM or sham treatment for four consecutive days (days +1 to +4). On days +4, +7, and +11, OM grade, pain (following a 0-10 numeric pain rating scale, NRS) and need for analgesics were evaluated by an operator blinded to treatment.

Results: Fifty-one patients were allocated to the PBM group, and 50 were allocated to the sham group. In total, 93.7% of PBM patients and 72% of sham patients had OM grade < 3 WHO on day +7 (P = 0.01). A significant reduction of pain was registered on day +7 in the PBM versus sham group (NRS 1 [0-3] vs. 2.5 [1-5], P < 0.006). Reduced use of analgesics was reported in the PBM group, although it was not statistically significant. No significant adverse events attributable to treatment were recorded.

Conclusions: PBM is a safe, feasible, and effective treatment for children affected by chemotherapy-induced OM, as it accelerates mucosal recovery and reduces pain.

Preliminary study in a new protocol for the treatment of oral mucositis in pediatric patients undergoing hematopoietic stem cell transplantation (HSCT) and chemotherapy (CT).

Lasers Med Sci 2017 Aug 29;32(6):1423-1428. Epub 2017 Jun 29.

Oral mucositis (OM) is a debilitating and serious side effect in patients undergoing hematopoietic stem cell transplantation (HSCT) and chemotherapy (CT). Laser therapy is becoming a promising treatment option in these patients, avoiding the necessity of enteral/parenteral nutrition. The aim of this study was to evaluate the efficacy of laser therapy in patients affected by oral mucositis induced by chemotherapy and HSCT. Sixteen onco-hematological pediatric patients receiving chemotherapy and hematopoietic stem cell transplantation, affected by oral mucositis, were enrolled in this study. They were divided in two randomized groups: the laser group and the placebo-control group. Patients in the laser group were treated with HPLT (970 ± 15 nm, 3.2 W (50%), 35-6000 Hz, 240 s) for four consecutive days, once a day; and placebo group underwent sham treatment. The assessment of mucositis was recorded through WHO Oral Mucositis Grading Objective Scale, and pain was evaluated through Visual Analogue Scale (VAS). Patients were monitored and evaluated 3, 7, and 11 days after the first day of laser therapy. Once OM was diagnosed, the patients had mucositis grading assessments before laser or sham application at day 3, 7, and 11 after first application. All patients of laser group demonstrated improvement in pain sensation from day 3 after first application of laser (p < 0.05), ulcerations reduced their dimensions and erythema disappeared. The patients of placebo group had improvement from day 7. In laser group, all mucositis were fully resolved from day 7 (p < 0.05). Oral mucositis negatively impacts on nutritional intake, oral hygiene, and quality of life. Laser therapy appears to be a safe and innovative approach in the management of oral mucositis. In this preliminary study, HPLT encourages to consider laser therapy as a part of onco-hematological protocol, providing to decrease pain and duration of OM induced by CT and HSCT. Further researches will be needed, especially randomized, controlled clinical trials with a large number of enrolled patients and a long term of follow-up to confirm the efficacy of laser therapy in prevention and control of OM in onco-hematological pediatric patients.

[Epidemiological study of dental and facial asymmetries in a sample of preschool subjects].

Epidemiol Prev 2015 Jan-Feb;39(1):45-51

Dipartimento di sanità pubblica, medicina sperimentale e forense, Università di Pavia.

Objectives: to identify the typologies of facial and dental asymmetries in a sample of children aged between 3 and 6 years and to correlate these asymmetries with possible morphological and functional situations.

Design: cross-sectional observational study.

Setting And Participants: sample of 95 subjects aged between 3 and 6 years. Clinical data were collected in 10 sessions conducted during school hours in April 2013 by a doctor of Dentistry at two preschools in the city of Sanremo (Liguria Region, Northern Italy) and a kindergarten in the city of Pavia (Lombardy Region, Northern Italy). To collect the data, a weighted clinical questionnaire was used.

Main Outcome Measures: presence and type of bad habit, type of breathing, presence and type of facial asymmetry, dental formula, presence of diastema, presence and type of occlusal asymmetries, presence and type of dental malocclusions.

Results: analysed sample consisted of 53.7% (51/95) of males and 46.3 % (44/95) females; the mean age was 4.3 ± 0.9 years. Most frequent facial asymmetry is orbits asymmetry (35%, 33/95); dental malocclusions are detected in 70%(67/95) of cases. High percentage of subjects (69.5%, 66/95) presents displacement between superior dental midline (SDM) and inferior dental midline (IDM). Several statistically significant associations are observed: in particular, asymmetry of molar ratios is linked to asymmetry of the cheekbones and displacement of the SDM; facial midline has statistical association with asymmetry of the cheekbones (p <0.001).

Conclusions: the results of this study agree with scientific literature, in particular as regards the prevalence of compromising habits observed and the close correlation between: the presence of dental malocclusions and the presence of compromising habits, the presence of dental malocclusions and the presence of oral breathing.

Combined technique with polyethylene fibers and composite resins in restoration of traumatized anterior teeth.

Dent Traumatol 2004 Jun;20(3):172-7

Department of Paediatric Dentistry, Faculty of Dentistry, University of Pavia, Pavia, Italy.

Traumatized anterior teeth need quick esthetic and functional repair. Esthetic requirements of anterior teeth require the use of composite materials which, in the most complex cases, can be used in association with fibers so as to improve their mechanical resistance. Many kinds of fibers are available. The authors considered parameters such as physical properties, water absorption, ease of cutting and of laying. Polyethylene fibers appear to have the best properties in elasticity, translucency, adaptability, tenaciousness, resistance to traction and to impact. Fifteen children, between 7 and 13 years old, with crown fractures of the anterior sector were treated. In the case of a simple crown fracture, the missing part was restored by polyethylene fibers and composite resins. In the case of a complex crown fracture needing endodontic treatment, the fibers were used as a central core stump in order to restore the dental morphology. At control examinations, the teeth restored by this technique were acceptable, both in function and in aesthetics. Thus, the authors recommend this combined technique for predictable restoration of traumatized anterior teeth.
