Controversy regarding the need for prophylactic removal of impacted third molars: An overview
Conclusion: Preventive removal of 3Ms at a young age is justified because retained 3Ms are at high risk of developing various pathologies. In addition, at older ages extraction of 3Ms becomes more complex, with an increased rate of complication due to deteriorated systemic physiologic conditions and changes in bone physiology.

Can extra-short dental implants serve as alternatives to bone augmentation? A preliminary longitudinal randomized controlled clinical trial
Conclusion: Short dental implants may offer an alternative for implant placement in an atrophic jaw; however, they are associated with reduced first-year survival rate. Short dental implants should be used judiciously in light of this potential predicament, and alternatives assessed. (Source: Quintessence International)

Randomized clinical trial on the comparison of bleaching outcomes using either ozone or hydrogen peroxide
AL-Omiri, Mahmoud K. / Lamfon, Hanadi A. / Al Nazeh, Abdullah A. / Kielbassa, Andrej M. / Lynch, EdwardPage 625 - 634Objective: To evaluate the efficacy of in-office tooth bleaching following application of either ozone (O3) or hydrogen peroxide (H2O2).Method and Materials: 32 participants were randomly distributed into two groups (n = 16 each). Participants' maxillary anterior teeth were treated with ozone (produced via a healOzone X4 device; Curozone) for 60 seconds in Group 1, or with 38% H2O2 for 20 minutes in Group 2. Tooth shades were evaluated by means of a colorimeter (CR-400, Minolta) measuring Vita classic shades...

Management of localized aggressive periodontitis: A 30-year follow-up
Petit, Catherine / Huck, Olivier / Amar, Salomon / Tenenbaum, HenriPage 615 - 624This case report describes the long-term follow-up of a patient with localized aggressive periodontitis over a 30-year period. A 16-year-old woman was referred for periodontal assessment after starting orthodontic treatment. The patient was treated initially by combined nonsurgical and antimicrobial therapy, and autotransplantation of maxillary third molars in place of maxillary first molars, followed by a regular supportive periodontal treatment program. This challenging case demonstrated that elimination of putative bacterial pathogens and l...

Tuberosity versus palatal donor sites for soft tissue grafting: A split-mouth clinical study
Amin, Peter N. / Bissada, Nabil F. / Ricchetti, Paul A. / Silva, Andre Paes B. / Demko, Catherine A.Page 589 - 598Objective: To compare postoperative pain associated with palatal and tuberosity donor sites for soft tissue grafting, and to evaluate the outcomes in both the donor and recipient sites.Method and Materials: Twenty healthy nonsmokers requiring bilateral soft tissue grafts were recruited for the study. For the 10 patients who required free gingival graft (FGG), 10 epithelialized grafts were taken from the tuberosity and 10 from the palate. The other 10 patients who required coronally advanced flap (CAF) and conne...

The efficacy of orthodontic treatments for anterior crowding with Invisalign compared with fixed appliances using the Peer Assessment Rating Index
Conclusion: More than 90% of the subjects treated with Invisalign achieved a significant improvement, as shown by the PAR scores. A need for additional aligners was reported for 37% of the patients. Fixed bonded retainers seem to be a good option in preventing tooth relapse after Invisalign and fixed conventional treatments. (Source: Quintessence International)

Peri-implant tissue score (PITS) as a measure of success, applied to 869 dental implants from a retrospective clinical study
Conclusion: The PITS withstood the tests. It responds to an existing need in the field, is widely accessible and inexpensive, and, thus, shows promise for use in general dental practice. (Source: Quintessence International)

Color stability, psychosocial impact, and effect on self-perception of esthetics of tooth whitening using low-concentration (6%) hydrogen peroxide
The objective efficacy ( ΔE) of 37.5% H2O2 (9.06 ± 2.96) was significantly higher than that of 6% H2O2 (5.69 ± 3.06). The results of the subjective assessment were not statistically different. There was a positive impact on esthetic auto perception (OHIP-14, P (Source: Quintessence International)

Determining the interchangeability of KaVo PROTAR semi-adjustable articulators
Conclusion: The majority of articulators tested did not pass the 166- µm criterion to establish them as interchangeable. Therefore, in order to maintain accuracy while producing restorations, it is advisable to use the same articulator throughout the entire process, both at the clinic and in the dental laboratory.

12 years' preservation of maxillary permanent incisors with cervical root fractures adjacent to aggressive periodontitis: Report of a case
Tobiska, Sandra / Krastl, GabrielPage 543 - 548This case report presents long-term results following horizontal root fracture of both maxillary central incisors in a 19-year-old woman with aggressive periodontitis. Due to extensive marginal bone loss and the close proximity of the fracture lines to the bottoms of the periodontal pockets, the prognosis of both teeth was uncertain at the time of the accident. Nevertheless, a conservative treatment strategy consisting of splinting and nonsurgical periodontal therapy was initiated. Follow-up at 12 years after the start of treatment revealed a stable situation from clinical and...

Management of heat-induced bone necrosis following thermal removal of gutta-percha
Livada, Rania / Hosn, Kalid / Shiloah, Jacob / Anderson, K. MarkPage 535 - 542Many endodontically treated teeth require a post to improve the retention of the coronal restoration, which necessitates removal of the coronal part of the gutta-percha from the canal by thermal method, among other techniques. However, this technique carries the risk of heat conduction to the attachment unit of the periodontium and infliction of permanent damage especially in cases where the remaining root's dentin walls are thin. The overall objective of this article is to report on the clinical manifestations, histologic description, and period...
