Introduction. Vitamin D deficiency and periodontitis are common diseases among people. These conditions interact with each other and worsen the patient’s health. Modern dentistry aims to rehabilitate oral health and bring it back to the original state or even improve aesthetics. Without analysing the general health conditions of patients and without a multidisciplinary approach, it is sometimes not possible to solve a case such as we describe. This study shows how a vitamin D deficit can influence the choice of dental treatment. The patient, a 40-year-old woman, in generally good health, came to our observation complaining about pain during mastication, and profuse bleeding during home hygiene maneuvers. She wished to solve this situation. Materials and Methods. Since the patient did not respond well to the initial periodontal therapy, we carried out some accurate research concerning the patient’s previous clinical history, and as we suspected that a vitamin D deficit might be involved, a chemical test for vitamin D was carried out and the results confirmed our suspicions. The team programmed the following therapeutical plan: Phase 1—rehabilitation of normal values of vitamin D with the support of an endocrinologist; Phase 2—full mouth disinfection; Phase 3—periodontal surgical restorative therapy; and Phase 4—orthodontic therapy and fixed prosthetics rehabilitation. Results. The results for this clinical case were extremely satisfying; we were able to bring the periodontal illness under control; resolve the orthodontic problems; and rehabilitate the patient both functionally and aesthetically. Conclusion. Thanks to the collaboration and communication between specialists from different sectors of medicine and dentistry, the clinical case was solved with absolutely satisfactory results.

Background: Modern cone beam computed tomography (CBCT) acquisition and three-dimensional (3D) image processing, combined with direct metal laser sintering (DMLS), allows custom-made, root-analogue implants (RAIs)., Purpose: To demonstrate how DMLS permits customized titanium RAI production, with immediate insertion and restoration in a fresh extraction socket of the anterior maxilla., Materials and Methods: A titanium RAI perfect copy of the radicular unit needed for replacement was created by customized DMLS, and inserted into a fresh extraction socket of the esthetic area of the anterior maxilla., Results: Follow-up after 1 year: the DMLS RAI implant showed a satisfactory functional and esthetic integration, with no bone resorption or soft tissue recessions., Conclusions: The production of customized DMLS RAIs opens new interesting perspectives for immediate implantation., Key Words: Direct metal laser sintering, Root analogue implant.

Aim: Combined surgical-orthodontic treatment of impacted maxillary canines has developed significantly in the last few years, regarding management of both hard and soft tissues and forces of traction. The aim of this report is to describe a combined surgical-orthodontic approach used to treat an impacted maxillary canine and to value the functional and esthetic results after 5 years of followup., Materials and Methods: A 13-year-old boy had been seen by surgeons in the Operative Unit of Orthodontics of Policlinico Tor Vergata in Rome. Radiographic images showed intraosseous impaction of teeth 1.3 and 2.3 in a late mixed dentition, and the patient was scheduled for the combined surgical-orthodontic treatment., Results: After the five-year follow-up, the patient had a good occlusal stability. The maxillary canine that had been orthodontically repositioned showed an adequate width of attached gingiva, which was well keratinized, and the margin of free gingiva that followed the course of the cement-enamel junction. Bleeding was absent on probing, the periodontal pocket depth was < 4 mm, and there was no radiographically evident bone loss., Conclusions: The combined surgical-orthodontic technique used in this case (closed eruption towards the center of the alveolar ridge associated with conservative periodontal surgery, the adhesive technique, and controlled orthodontic traction) simulates physiological tooth eruption and results in proper alignment with good periodontal results. It should be considered as the treatment of choice for impacted teeth whose eruption is not precluded by the position of the tooth and/or the presence of ankyloses., Key Words: Mucoperiosteal flap, Surgical tecnique.

Background: Chronic periodontitis affects 47% of adult population over the age of 30. The first phase of periodontal treatment is always represented by scaling and root planning (SRP), that is a causal, non-surgical therapy that recognizes as primary aims the control of bacterial infection and the reduction of periodontal plaque-associated inflammation. Yet, another innovative causal therapy is represented by the irradiation of periodontal pockets with laser., Aim: To evaluate the effect of a 940-nm diode laser as an adjunct to SRP in patients affected by periodontitis., Materials and Methods: Sixty-eight adult patients with moderate-to-severe periodontitis were sequentially enrolled and undergone to periodontal examination (V1) in order to detect gingival index (GI), plaque index (PI) and probing depth (PD). The patients were randomly divided into two groups: the first (n=34) received SRP treatment alone, the control group (n=34) received SRP and 940-nm diode laser therapy., Results: Data were analyzed by Student's t-test, with two tails; for all clinical parameters, both groups reported statistically significant differences compared to basal values (p<0.0001). Both procedures were effective in improving GI, PI and PD, but the use of diode laser was associated with more evident results., Conclusions: Considered the better clinical outcomes, diode laser can be routinely associated with SRP in the treatment of periodontal pockets of patients with moderate-to-severe periodontitis.
