- Prevalence and Reasons for Extraction of Endodontically Treated Teeth in Adult Nigerians. [Journal Article]
- JCJ Contemp Dent Pract 2018 Dec 01; 19(12):1469-1473
- CONCLUSIONS: The association between age and extraction was proven. Caries, vertical root fracture and endodontic reasons accounted for the commonest cause of extraction in the mandible; while in the maxilla, endodontic reasons and cusp fracture caused extractions most often.The reasons for extraction of endodontically treated teeth are different between maxilla and mandible.
- Assessment of gait kinetics in post-menopausal women using tri-axial ankle accelerometers during barefoot walking. [Journal Article]
- GPGait Posture 2019 Jan 15; 69:85-90
- CONCLUSIONS: This study is the first to show a strong relationship among ankle accelerometry data and high fidelity lower-limb loading approximations in post-menopausal women. The results provide the first steps necessary for estimation of real-world limb and joint loading supporting the goals of accurate PA tracking and improved individualization of clinical interventions.

INTRODUCTION: In February 1970, halfway through a Polaris submarine war patrol in SSBN-02 HMS Renown (port crew), a Petty Officer presented to the sick bay in excruciating pain with a broken upper left molar tooth. The zinc oxide/clove oil mixture would not stick on to the vertical face of the fracture. In preparation for such events, Royal Navy (RN) submarine medical officers are taught excellent fundamental dental skills. In this case, it seemed a very difficult job to extract the remains of the tooth. The author reports the first known use of glass fiber/resin in the RN to crown and treat a fractured molar, cover the root, and save the tooth, and to recommend that all military and civilian medical staff working anywhere in isolation with no dental facility locally be given similar training to that which RN submarine medical officers receive before being sent on extended dives.Brooks CJ.

- Accuracy of detecting vertical root fractures in non-root filled teeth using cone beam computed tomography: effect of voxel size and fracture width. [Journal Article]
- IEInt Endod J 2019 Jan 20
- CONCLUSIONS: Cone beam computed tomography was accurate for detecting VRF in non-root filled teeth. Fracture width had an effect on the detection of VRF. The effect of the voxel size on the detection of VRF depended on the CBCT unit used.
- Effect of intracanal cryotherapy on the fracture resistance of endodontically treated teeth. [Journal Article]
- AOActa Odontol Scand 2019; 77(2):164-167
- CONCLUSIONS: Application of intracanal cryotherapy as a final irrigant reduced the vertical fracture resistance of prepared roots when compared to the control group.
- Effect of object position in the field of view and application of a metal artifact reduction algorithm on the detection of vertical root fractures on cone-beam computed tomography scans: An in vitro study. [Journal Article]
- ISImaging Sci Dent 2018; 48(4):245-254
- CONCLUSIONS: Diagnostic accuracy was higher with central positioning than with peripheral positioning, irrespective of whether the MAR algorithm was applied. However, the effect of the MAR algorithm was more significant with central positioning than with peripheral positioning of the object in the FOV. The clinical experience and expertise of the observers may serve as a confounder in this respect.
- Tissue preservation through socket-shield technique and platelet-rich fibrin in immediate implant placement: A case report. [Case Reports]

In this report, a combination of socket-shield technique (SST) and platelet-rich fibrin (PRF) technique was used for immediate implant placement on a fractured central incisor. During the follow-up visit, cone beam computed tomography (CBCT) and clinical observation were used to evaluate the preservation outcome of peri-implant bone and gingiva.
- Root dentinal microcracks: a post-extraction experimental phenomenon? [Journal Article]
- IEInt Endod J 2018 Dec 14
- CONCLUSIONS: This in situ cadaveric model revealed the lack of pre-existing dentinal microcracks in non-endodontically treated teeth. Thus, the finding of dentinal microcracks observed in previous cross-sectional images of stored extracted teeth is unsound and not valid. It should be assumed that microcracks observed in stored extracted teeth subjected to root canal procedures are a result of the extraction process and/or the post-extraction storage conditions. Therefore, as a consequence, the presence of such dentinal microcracks in stored extracted teeth - observable in cross-sectional images of the roots - should be referred to as experimental dentinal microcracks.
- Four-Year Follow-up of Increased Vertical Dimension of Occlusion using Resin Composites. [Journal Article]

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.
