    2014 Mar/Apr; 62(2):20.  

    This in vitro study sought to evaluate the sealing ability of 3 root canal obturator systems after immersion in simulated body fluid for 1 year. Specimens were divided into 3 groups (n = 10) according to the obturation manufacturer-specified system, and then immersed in simulated body fluid. This study demonstrated that the tested systems were unable to keep their sealing ability stable during the first year, and at 12 months, all 3 systems showed increased flow rates (P < 0.0001).

  • Myofascial Pain/Occlusion Precision occlusal splints and the diagnosis of occlusal problems in myogenous orofacial pain patients

    Glenn M. Kidder, DDS, FAGD
    Roger A. Solow, DDS
    2014 Mar/Apr; 62(2):24.   

    Research has shown that occlusal interferences affect masticatory muscle pain or dysfunction. Resolution of these problems with precise occlusal correction indicates that dental occlusion is a causative or contributory factor. However, some reports conclude that occlusion is unrelated to masticatory muscle pain or dysfunction. An explanation for this discrepancy in findings is that these nonconfirmatory studies had not documented any pretreatment or corrected occlusion. The rationale and requirements for proper occlusal splint fabrication with a verified therapeutic occlusion are presented.

    This study compared the effectiveness of 2 surgical root coverage techniques—semilunar coronally positioned flap and coronally advanced flap—using the clinical parameters of periodontal tissues from patients with Miller Class I gingival recession. Both groups showed significant reduction of plaque and gingival indices, and an improvement in clinical attachment levels and probing depth. However, results showed the coronally advanced flap technique was deemed more effective due to significant clinical attachment level gains.

  • Root Caries & Treatment Influence of instrumentation techniques and irrigating solutions on bond strength of glass fiber posts to root dentin

    Eduardo Fernandes Marques, MSc
    Carlos Eduardo da Silveira Bueno, PhD
    Heloisa Helena Pinho Veloso, PhD
    Gustavo Almeida, MSc
    Sergio Luiz Pinheiro, PhD
    2014 Mar/Apr; 62(2):50.  

    This study sought to evaluate how instrumentation techniques and irrigating solutions affected the bond strength of glass fiber posts. Irrigation with 2.5% NaOCl reduced the bond strength of fiber posts significantly (P < 0.01), while CHX showed no effect (P > 0.05). It was concluded that irrigation with 2.5% NaOCl has a negative effect on micromechanical retention of glass fiber posts, whether manual or rotary instrumentation is used.
