Basic Science Utilization of cone beam computed tomography to determine the prevalence and anatomical characteristics of bifurcated inferior alveolar nervesThomas Y.H. YoonFull Article (PDF)

Thanhphuong N. Dinh
In a study of the prevalence and anatomical characteristics of bifurcated inferior alveolar nerves, cone beam computed tomography found bifurcations in 13.4% of 194 patients. Fourteen bifid nerves were type 1, with a single foramen and narrower inferior canal, and 16 were type 2, with a short superior canal extending to the second or third molar.

Fixed Prosthodontics Fracture resistance of bonded CAD/CAM restorations with standard or extended preparationsStephen C. ArnasonFull Article (PDF)
Villa L. Guillory
Clifton W. Bailey
Kraig S. Vandewalle
This study evaluated the fracture resistance of teeth with standard or extended preparations after restoration with lithium disilicate or resin nanoceramic inlays. Although bonded restorations reinforced the tooth structure, the fracture load was significantly lower in teeth with extended preparations. The type of restorative material did not significantly affect the fracture load.

Orofacial Pain Diagnostic accuracy of panoramic radiography and MRI for detecting signs of TMJ degenerative joint diseaseShanti KaimalFull Article (PDF)
Eric L. Schiffman
A study of more than 700 subjects examined the accuracy of different imaging modalities for detecting signs of temporomandibular joint (TMJ) degenerative joint disease. Panoramic radiography and magnetic resonance imaging (MRI) had poor sensitivity but high specificity for detecting subcortical cysts, surface erosion, and generalized sclerosis that were visible on computed tomography (CT). MRIs demonstrated adequate diagnostic accuracy for osteophyte formation, but panoramic radiographs did not. Use of CT for diagnosis of TMJ degenerative joint disease is recommended to avoid false-negative findings.

Implants Retentive force variations of stud attachments for implant overdenturesPaul J. BoulosFull Article (PDF)
Linda A. Akiki
Joseph E. Makzoumé
Fadi S. El Hage
When overdenture attachments were investigated in vitro, Locator attachments demonstrated a more stable and sustained retentive force than O-ring/ball attachments in dry testing. In wet testing, both attachments showed acceptable retentive forces over time. Locator or metal-to-metal attachment components would be preferable for patients with dry oral conditions, but there should be no significant difference between the performance of the attachment types in saliva-moistened oral cavities.

Pediatric Dentistry Multidisciplinary management of an impacted maxillary central incisor associated with supernumerary teeth: a case reportPaula Corrêa Silveira da SilvaFull Article (PDF)
Leandro Borges Araújo
Lidiane Lucas Costa e Silva
Vivien Thiemy Sakai
An 11-year-old patient whose permanent maxillary right central incisor was impacted due to the presence of 2 supernumerary teeth underwent extraction of the supernumerary teeth and orthodontic traction of the impacted central incisor. Treatment resulted in functional and esthetic oral rehabilitation.

Basic Science Evaluation of marginal leakage after mechanical fatigue cycling of composite inlays luted with different cementsDario MelilliFull Article (PDF)
Enzo Maria Giuseppe Cumbo
Vinicius Felipe Wandscher
Luiz Felipe Valandro
Dye penetration testing to evaluate the marginal microleakage of composite resin inlays luted with 3 different cement systems revealed that inlays luted with Calibra and Charisma Flow showed greater microleakage, notably at the cervical margins. Inlays luted with RelyX Unicem showed the least dye penetration.

Pediatric Dentistry Complete overdenture fabrication for a 12-year-old child with dentinogenesis imperfecta type 2Sabrina GarcesFull Article (PDF)
Robert M. Newman
Overdentures were fabricated for a 12-year-old boy with dentinogenesis imperfecta type 2 in order to improve dental esthetics, reconstruct overall function, and maintain the vertical dimension of occlusion until he reaches full adult development. The prostheses successfully restored function and improved esthetics, increasing the patient’s self-esteem.

Restorative Dentistry Effect of a dentifrice containing nanohydroxyapatite on the roughness, color, lightness, and brightness of dental enamel subjected to a demineralization challengePatrícia Queiroz Rocha dos ReisFull Article (PDF)

Marcos Oliveira Barceleiro
This study compared the effects of a nanohydroxyapatite (nanoHAp) and a sodium fluoride dentifrice on the surface characteristics of bovine enamel subjected to pH cycling. The nanoHAp-containing dentifrice promoted less superficial roughness after 14 days, but the performances of both dentifrices were similar in relation to color variation, lightness, and brightness. No effective esthetic remineralization was achieved in either group.

Endodontics Reimplantation of an avulsed mature permanent tooth after 6 days: a 1-year follow-upPriscilla Santana Pinto GonçalvesFull Article (PDF)

Carlos Eduardo Gomes Couto Filho
Heitor Marques Honório
A permanent maxillary central incisor was reimplanted in an 11-year-old boy 6 days after avulsion of the tooth. At the 1-year follow-up, the tooth exhibited clinical function without mobility or pain. Although there were radiographic signs of ankylosis, treatment was deemed successful because the tooth and surrounding bone had been preserved, delaying the need for definitive treatment in the growing child.

This preclinical study in dogs investigated the effectiveness of using autologous platelet-rich plasma (PRP) to heal erosive lesions in the oral cavity. In the dogs receiving autologous PRP, no traces of inflammatory symptoms were found at 14 days, while the control group exhibited signs of nonspecific chronic inflammation in the oral mucosa at 14 days.
