Mandibular fractures are common facial injuries [1-3]. The prognosis of these fractures is influenced by many confounding variables which directly or indirectly determine their treatment outcomes [4-7]. There is no consensus in the literature on the most prevalent factors associated with post-operative complications due to the treatments of mandibular fractures. The treatment of these fractures...

Though anti-vascular endothelial growth factor therapy has become the standard treatment for exudative age-related macular degeneration (AMD), retreatment after the initial loading injection is inevitable in most eyes with residual or recurrent exudative changes. In the present study, we studied 140 treatment naïve eyes with typical neovascular AMD (n = 71) or polypoidal choroidal vasculopathy ...

OBJECTIVES A recent trial showed the clinical benefit of retreatment with varenicline in subjects failing on the initial treatment, or relapsing after initial success. The objective of this study was to evaluate the cost-effectiveness of retreatment with varenicline compared with other smoking cessation interventions. METHODS A published Markov model was adapted to compare one quit attempt of...

INTRODUCTION World Health Organization recommendations of bidirectional screening for tuberculosis (TB) and diabetes have been met with varying levels of uptake by national TB programs in resource-limited settings. METHODOLOGY Kibong'oto Infectious Diseases Hospital (KIDH) is a referral hospital for TB from northern Tanzania, and the national referral hospital for multidrug-resistant (MDR)-TB...

Introduction: Endodontic failure may arise mainly from persistent intra-radicular infection from remaining bacteria in the root canal. As a result, retreatment is the most appropriate way of dealing with failed cases. However, many clinicians choose to perform periapical surgery, on the grounds that it is simpler and has immediate results. The resected teeth with insufficient root canal treatme...

Sustained viral response (SVR) rates for direct-acting antiviral (DAA) therapy hepatitis C virus (HCV) infection routinely exceed 95%. However, a small number of patients require retreatment. Sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) is potent DAA combination primarily used the retreatment who failed by therapies. Here we evaluate outcomes effects resistance-associated substitution...

introduction: retreatment of endodontically treated teeth is a challenge that requires complete removal of the previous filling material. several techniques are indicated for this procedure. the present review tries to identify the most efficient method for extirpation of resilon (rs) root fillings and to compare the speed and efficacy of rs and gutta-percha (gp) root filling removal. methods a...

PURPOSE To evaluate the visual and refractive results of laser in situ keratomileusis (LASIK) retreatment on eyes with residual myopia with or without astigmatism. METHODS LASIK retreatment was performed on 35 eyes of 23 patients for correction of residual myopia, with or without astigmatism, with a mean manifest spherical equivalent refraction of -2.17+/-0.82 D (range, -1.00 to -3.87 D) and ...

UNLABELLED The aim of this clinical study was to assess 1032 endodontically treated roots in relation to: (i) the success rate of retreatment (612 roots)--only cases that had recall examinations of 6 months or longer were evaluated; (ii) the influence of various factors on the technical and clinical results of the retreatment; and (iii) the consequences of radiographic monitoring of 420 asympto...

Objective. To compare the efficacy of ProTaper retreatment files in removing three different obturating materials. Study Design. Forty-five human, single-rooted premolars were divided into three experimental groups. Group 1 was obturated with gutta-percha and AH Plus sealer, Group 2 was obturated with gutta-percha and zinc oxide eugenol sealer, and Group 3 was obturated with GuttaFlow. Retreatm...
