The objectives of this case report were to treat a severe loss of the vertical dimension of occlusion with indirect composite and to evaluate the durability of the restorations. A 55-year-old male complains from severe wear of teeth, leading to a change in normal occlusal plane. Two major treatment modalities were proposed to this patient; a conventional invasive crown placement with root canal treatments or a minimally invasive approach relying on adhesion. The latter was adopted and used to treat this patient. This paper describes a step-by-step approach of the different treatment phases starting with teeth preparation, then provisional prostheses, and ending with the placement of indirect anterior veneers and posterior onlays, all made with laboratory resin composite. Satisfactory clinical results were observed over the 4-year follow-up, with minimum failures limited to one partial fracture of inlay treated with direct adhesive repair.

Chronic periapical lesions in necrotic teeth with open apex are difficult to manage. The situation becomes more complex if the tooth has a fracture line. This case report describes the management of a traumatised tooth that had already undergone unsuccessful endodontic treatment with a large periapical lesion and open apex along with a fracture line in the root. An attempt was made to save the tooth by using mineral trioxide aggregate (MTA) cement for orthograde filling, retrograde filling and also for sealing of the fracture line. Moreover, the bone defect was filled with autogenous bone harvested from the external oblique ridge. MTA, a bioactive tricalcium silicate cement, has been used in treating complex endodontic cases as it shows promising potential by inducing the biological mechanisms necessary for repair of involved teeth. A 1-year follow-up showed progressive healing as evident by radiographs and lack of any clinical signs and symptoms.
- Bone regeneration around immediate placed implant of molar teeth with autologous platelet-rich fibrin: Two case reports. [Case Reports]
- MMedicine (Baltimore) 2018; 97(44):e13058
- CONCLUSIONS: The results suggested that PRF could solely serve as a bone scaffold in 4-wall bony defects, or can be combined with xenograft in 3-wall bony defects during immediately placed implants in molar regions, exhibiting excellent biocompatibility and good soft and hard tissue healing.

Full-coverage restorations represent a well-known rehabilitation strategy for compromised posterior teeth; in the last years, new ceramic materials like zirconia have been introduced and widely adopted for the prosthetic management of molar and premolar areas. A long-term follow-up of a maxillary premolar rehabilitation using a veneered zirconia crown is presented; after ten years of uneventful clinical service of the tooth-restoration complex, a serious complication-namely, a vertical root fracture (VRF)-occurred. An extended time lapse (9 years) between the end of restorative procedures and development of symptoms due to VRF has been observed. On the other hand, a complete functional and esthetic integrity of the zirconia crown (without chippings or crack development) is documented along the follow-up period. Due to periodontal breakdown and severity of fracture, the premolar was extracted. The illustrations of our late failure, aetiological factors, and available data on the literature regarding VRF are addressed. Patients and clinicians should be aware of potential occurrences of some long-term, serious complications when dealing with previously treated and/or structurally weakened teeth. The development of a VRF might be unexpected and might occur many years after the end of tooth rehabilitation, despite adoption of contemporary restorative protocols and techniques.

- CONCLUSIONS: Protocols with a smaller voxel size and field of view seemed to favor the detection of VRF in teeth with intracanal metallic posts.
- Circumferential root strains generated during lateral compaction with stainless steel vs. nickel-titanium finger spreaders. [Journal Article]

The circumferential strains created in the radicular dentin by nickel-titanium (NiTi) and stainless steel (SS) finger spreaders (FSs) during a simulated clinical procedure of lateral compaction were compared after minimal (size 50) and extensive (size 100) canal preparations. Nineteen maxillary central incisors underwent minimal preparation, while 10 underwent an extra phase of extensive preparation. Four miniature strain gauges were bonded circumferentially in the apical third of the root (buccal, lingual, mesial, and distal). Lateral compaction was performed using either NiTi-FSs or SS-FSs. Force and strains were continuously recorded. The maximal strains (with and without normalization according to force) were recorded. The SS-FSs generated higher maximal strains normalized according to force compared with the NiTi-FSs. The maximal normalized strains were higher by 37%-43% for the mesial and distal aspects and by 6%-14% for the buccal and lingual aspects after the minimal preparation and by 24%-28% for the mesial and distal aspects and by 19%-20% for the buccal and lingual aspects after extensive preparation. The maximal normalized strains increased by 30%-70% from minimal to extensive preparations, with two teeth exhibiting vertical root fracture while compaction with SS-FS. The NiTi-FSs induce less strain in root dentin than the SS-FSs and thus may contribute less to the risk of vertical root fracture.

- CONCLUSIONS: The major risk for VRFs was represented by those presenting radiological image of J-shaped or "halo" radiolucency, periodontal pocket depth ≥5 mm, sinus tract, and periodontal swelling or abscess simultaneously.

- JFJ Formos Med Assoc 2018 Aug 22
- CONCLUSIONS: For a VRF tooth, in addition to tooth extraction, intentional replantation combined with root fragment bonding with 4-META/MMA-TBB resin is a successful treatment modality that can be used to preserve a complete VRF tooth.

- Detection of Vertical Root Fractures Using Cone-Beam Computed Tomography in the Presence and Absence of Gutta-Percha. [Journal Article]
- SScientificWorldJournal 2018; 2018:1920946
- CONCLUSIONS: The intracanal filling materials such as gutta-percha reduce the diagnostic ability of vertical root fractures. Hence, it is recommended to remove those materials from root canals before imaging to improve the diagnostic potential of CBCT.
