“…Recent attempts to diminish Ni use in most industrial products have led to an increase in the use of different metal compounds for specific destinations such as the alloys used in orthopaedics, jewellery and dentistry [9]. For instance, the use of palladium (Pd) increased in the past 10 years [10] also due to the fact that dentistry alloys containing Pd appear more resistant to mechanical wearing effects [11,12]. Similarly, rhodium (Rh), which is primarily used as an alloying agent to harden platinum and Pd, it is now employed in electrical material because of its low electrical and contact resistance, in jewellery (platings of silver or white gold because of its silvery white colour), in optical instruments and dental prostheses.…”

Background: Recent attempts to diminish nickel use in most industrial products have led to an increasing utilization of alternative metal compounds for destinations such as the alloys used in orthopaedics, jewellery and dentistry. The present study was undertaken with the aim to evaluate the potential for an allergic response to nickel, palladium and rhodium on the basis of antigenspecific induction of inflammatory/regulatory cytokines, and to characterize, according to the cytokine profiles, the nature of simultaneous positive patch tests elicited in vivo.

“…However, there is convincing evidence that have shown that there is no difference in postoperative sensitivity in cases with and without bonding agents thus have seriously questioned the benefits of using bonding agents for sensitivity management. 24 Previously one study has shown an adhesive to be inferior to varnish in the seal it provides, 25 others have shown adhesives and varnishes to exhibit similar degrees of microleakage. 26,27 Our Study also is in line with one of the studies carried out in Agha Khan University, Karachi, showing that there was no difference in the postoperative sensitivity in the conventional and the bonded amalgam restorations in the Class I preparations.…”

The reintegration of partial edentulism patients is the utmost common treatment performed by dental practitioners in relations of frequency & occurrence, even though the general decline in tooth loss seen in recent times. There is broad agreement among dental professionals that osseointegrated implant-supported prostheses are the preferred method for replacing an edentulous gap caused by one or more lost teeth. These implants have been shown to provide several benefits for both physical and mental health. Objectives: The current retrospective study sought to define and assess the 60 months follow-up of implants inserted in patients who needed sinus floor elevation surgery in the maxillary arch. Following a single-stage surgical method with delayed implant insertion, the impact of various RABH & the usage of graft and graft less methods were evaluated. Methodology: Patients chosen for the current retrospective study were selected from the data-based logbooks kept by the oral surgery department between January 2017 and December 2022. All patients who had concomitant lateral sinus floor elevation & implant insertion from the same department were evaluated in the current study after obtaining formal approval from the IRB of the institute. Results: 86 grafted sinuses received a sum of 239 implants, each assessing 10 & 12 millimeters in length and 4 or 5 mm in breadth. Specific measurements revealed that the majority were 4 mm broad & 10 mm long. Using a manual torque wrench, it was determined that all implants, regardless of size, attained an insertion torque of >35 Ncm at the moment of implantation. In 41 patients, xenograft was employed, corresponding to 60 sinuses; in contrast, in 45 patients, graft-less surgery was performed, corresponding to 62 sinuses. An average follow-up of 43 months was used. Conclusion: Maxillary sinuses with a RABH of more than four millimeters can be effectively transplanted using a single-stage xenograft technique. One-stage graft-less surgeries with blood clot alone & swift implant implantation should only be used in sinuses with a RABH > 6 mm since they have lower success rates. Practical Implication: The following study will help oral surgeon in choosing the surgery carried out for the implant placement involving the sinuses. Keywords: Dental Implants, Bone Replacements, Sinus Augmentation, Grafting Materials

“…Moreover, data on local [8] and systemic toxicity [9] seemed to prove Pd safety. Due to its relatively cheap price, suitable processing qualities, and due to the fact that dentistry alloys containing Pd appear more resistant to mechanical wearing effects [10,11], exposure to Pd from use of dental appliances become more frequent in the population.…”

Palladium (Pd) belongs to the platinum group elements and its use has more than doubled in the past ten years. Encouraged by positive patch test results in some patients suffering from oral syndromes, Pd was included in the routine patch testing for contact dermatitis. In the present study, differences in the trend of sensitization to Pd in a contact dermatitis clinic population between 1996 and 2006 were evaluated. Since many in vitro studies have confirmed the corrosion of dental alloys and indicated that metal components are released in the oral cavity, Pd content was examined in leaching solutions from dental prostheses and in samples of saliva, serum and urine of subjects with adverse reaction to dental prostheses. Measurements were performed by means of Sector Field Inductively Coupled Plasma-Mass Spectrometry (SF-ICP-MS). Results showed that the frequency of mono-reactions to Pd are increased from 1996 (0.11%) to 2006 (1.6%), suggesting that this metal is becoming a "new" potential allergen. The mean values of Pd levels detected in urine were higher than those found in saliva and in serum. All biological samples collected from patients showed significantly higher levels of Pd than controls (saliva, 255 ng/L vs 11; serum, 60 vs 15; urine, 580 vs 20). Moreover, after removal of the prostheses a consistent reduction of Pd content in fluids was observed.
