Aim: The aim of the study was to assess the hindrances in communication between the prosthodontic office and the laboratory technicians through work authorization.

Setting And Design: A questionnaire-based survey was carried out to assess communication gap between dentist and lab technicians through work authorization for FDPs.

Materials And Methods: A total of 114 dental laboratory technicians were provided with a questionnaire regarding work authorization form via Google doc files. The survey focused questions pertaining to fulfilling the following areas of work authorization: patient's information, name of the prescribing dentist, material for the prosthesis, pontic design of the prosthesis, shade description, and date of completion of work.

Statistical Analysis Used: The number of responses received was statistically evaluated using Fisher's -test and nonparametric Spearman's correlation coefficient ( ≤ 0.05).

Results: Eighty-five (74.5%) out of 114 laboratory technicians surveyed responded to the questionnaire. The patient's general information was satisfactorily filled in 75%-100% of the forms. Information regarding the pontic design, staining diagram, and preferred margin were on the lower side of the scale ranging between 25% and 50%.

Conclusions: The survey concluded that areas of work authorization with respect to fixed dental prosthesis require attention and need to be adequately filled by the dentist. In addition, the study suggests that the foundation of communication skill training programs in work authorization should be laid from the undergraduate curriculum. The concerned authorized bodies/specialty organizations should formulate a standardized work authorization format which can bridge the wide gap between the crown and bridge office and laboratory.

A split-mouth clinico-radiographic comparative study for evaluation of crestal bone and peri-implant soft tissues in immediately loaded implants with and without platelet-rich plasma bioactivation.

J Dent Res Dent Clin Dent Prospects 2019 14;13(2):117-122. Epub 2019 Aug 14.

Department of Prosthodontics and Crown & Bridge, School of Dental Sciences, KIMSDU, Karad, India.

This study evaluated the viability of platelet-rich plasma for enhancement of osseous and associated soft tissue healing around single-piece implants, subjected to immediate loading and to compare it with a control site not treated with PRP. Twenty completely edentulous patients were selected and 2 one-piece implants with O-ball head were placed for mandibular overdenture. The implant on the right side was treated with PRP whereas the left side implant served as a control. All the cases were immediately loaded and marginal bone loss, probing depth, percussion, implant mobility and peri-implantitis were assessed and compared at 3, 6, 9 and 12 months. Overall analysis of the results showed less marginal bone loss, probing depth, percussion, implant mobility and periimplantitis around implants treated with PRP; however, the results were insignificant statistically. PRP can be used as a viable treatment adjunct in immediately loaded one-piece implants.

An In vitro Comparative Evaluation of Disinfectants on Standard and Clinical Microbial Strains on Heat Cure Resins.

J Clin Diagn Res 2017 May 1;11(5):ZC54-ZC58. Epub 2017 May 1.

Reader, Department of Oral and Maxillofacial Surgery, School of Dental Sciences, Krishna Institute of Medical Sciences Deemed University, Malkapur, Karad, Maharashtra, India.

Introduction: Oral cavity is colonised by numerous micro-organisms that form a biofilm on the acrylic resin. Hence, routine hygiene is essential to prevent oral mucosal inflammation and lesions. Knowledge of appropriate disinfecting agents for acrylic resins is crucial in this context.

Aim: To compare and evaluate the effectiveness of four commercially available disinfectants on heat cure acrylic resin specimens contaminated with standard and clinical strains of two micro-organisms commonly inhabiting the oral microflora.

Materials And Methods: Two hundred acrylic resin specimens (n=200), 10 in each group were contaminated in vitro with 1x10 cells/ml suspensions of standard and clinical strains of micro-organisms and were immersed in four disinfectants (1% sodium hypochlorite, 2% chlorhexidine digluconate, 2% glutaraldehyde and 3.8% sodium perborate) for 10 minutes. The control group was not subjected to any disinfection process. For collection of clinical strains, oral swab was passed over the buccal mucosa and grown on blood agar culture media. Organism confirmation was done by growing them on selective culture media. Final counts of micro-organisms per ml were performed by plating method for evaluation of microbial level reduction. Results obtained were subjected to ANOVA and Tukey's test.

Results: Standard strains of (C) and (S) subjected to various disinfectants showed varied mean Colony Forming Units per ml (CFU/ml) from <10,000 to 25,000 and <10000 to <50,000 respectively. Clinical strains and of (C) and (S) subjected to various disinfectants showed varied mean CFU/ml from <10,000 to 50,000 and from 10,000 to 50,000 respectively. Control groups showed maximum mean CFU/ml (>10). All intergroup comparisons were highly significant (p<0.001; HS) and intragroup comparisons were significant (p<0.05; S) except the comparison of clinical strains of subjected to 2% chlorhexidine digluconate and 2% glutaraldehyde which was found to be non significant (p>0.05; NS).

Conclusion: Almost 1% sodium hypochlorite was found to be the most effective disinfectant for both and . The least effective disinfectant being: 3.8% sodium perborate.

Evaluation of linear dimensional accuracy of hard chairside and laboratory heat cure reline resins at different time intervals after processing.

Indian J Dent Res 2014 Nov-Dec;25(6):686-91

Department of Prosthodontics, School of Dental Sciences, Krishna Institute of Medical Sciences, Deemed University, Malkapur, Karad, Satara, Maharashtra, India.

Context: Relining with heat cure denture base resin is time-consuming and the patient has to remain without dentures within this period. Recently, some autopolymerizing resins marketed as hard chairside reline systems with low exothermic heat allow the dentists to reline prosthesis directly in the mouth. However, the decision to use these materials must be based on physical properties such as dimensional accuracy that directly influences the accuracy of fit of the denture base.

Aim: The aim was to compare the linear dimensional changes of two hard chairside reline resins with two laboratory heat cure resins at 3 times intervals after processing.

Settings And Design: A stainless steel split mold (International Organization for Standardization 1567) was used for sample fabrication. Five measurements of the reference dimensions (AB and CD) were measured directly from the mold and the samples with a profile projector, and mean difference were calculated.

Subjects And Methods: Forty samples were fabricated by incorporating the split mold into first pour of denture flasks and packing each of the chairside reline resins ("Kooliner" and "Ufi Gel Hard") and laboratory heat cure resins ("Dental Products of India Heat Cure" and "Trevalon"). The mean difference in dimensional change at 3 times intervals (0 h, 4 days and 2 months) were calculated and subjected to statistical analysis.

Statistical Analysis Used: One-way ANOVA, RMANOVA and post hoc Tukey's tests.

Results: All resins showed different levels of significant shrinkage (P<0.001) after processing (T0) ranging from -0.128 to -0.310 mm. After 4 days (T1), there was significant shrinkage (P<0.001) ranging from -0.168 to -0.296 mm. After 2 months (T2), there was again significant shrinkage (P<0.001) ranging from -0.018 to -0.216 mm. Chairside reline resins showed less dimensional shrinkage at each time interval than the laboratory heat cure resins.

Conclusions: Hard chairside resins are dimensionally accurate than the laboratory heat cure resins.
