8%). Factors aggravating anxiety included gagging while impression making - 298 (59.6%), mouth fullness - 122 (24.4%), swallowing the impression material - 61 (12.2%), breathlessness - 20 (4%). 422 (84.4%) patients indicated comfort with the procedure being explained beforehand, 429 (85.8%) patients indicating more so in a language understood by them.

There is a greater need that the patient's expectations be understood and their doubts, concerns and fears be lessened by proper communication. Proper understanding of patient's mental attitude will help us improve the approach of dentists towards complete denture treatment in a more patient friendly way.

To evaluate the microleakage of metallic copings luted with three different commercially available luting cements.

Comparative evaluation in vitro study.

Thirty replicas of abutment analog were milled and divided into 3 groups. Nickel chromium copings were fabricated; marginal gap was evaluated with optical microscope and luted with Zinc Oxide Non Eugenol cement, Zinc Polycarboxylate cement and Zinc Phosphate cement. After Thermocycling, cemented specimens were placed into 0.5% aqueous solution of basic fuchsin solution for 24 hours for dye penetration. Copings were longitudinally sectioned and microleakage scores were evaluated.

Kruskal-Wallis analysis of variance (ANOVA) followed by Chi-Square test. Pairwise comparison of groups with Mann Whitney U test.

Mean microleakage score was least for Zinc Phosphate cement (1.075 ± 0.85) followed by Zinc Polycarboxylate cement (1.80± 0.23) and most for Zinc Oxide Non Eugenol (2.1± 0.37). The results of the study were statistically significant, P < 0.05.

Within the limitations of the study, it was found that all cements exhibited certain amount of microleakage. Zinc Phosphate cement exhibited a mean microleakage score that was significantly lower than Zinc Oxide Non Eugenol cement and Zinc Polycarboxylate cement. When microleakage scores of Zinc Oxide Non Eugenol cement and Zinc Polycarboxylate cement were compared, the difference was found to be insignificant indicating that microleakage in these cements is similar.

The objective is to evaluate the effect of shades of monolithic zirconia on the microhardness and sorption/solubility of the underlying two dual-cured resin types of cement.

Eighty samples of two dual-cured resin cement discs were polymerized under 60 monolithic zirconia discs in three shades and directly activated resin discs of cement were used as the control group (n = 10). After 24 h storage at 37°C in an incubator, Vickers microhardness and the sorption and solubility were measured.

Two-way ANOVA , one-way ANOVA, Independent t-test, Tukey's honestly significant difference, and Tamhane's T2 tests.

The mean microhardness of the Variolink N resin cements were significantly higher than Panavia SA ones (P < 0.001). Furthermore, Variolink N cements exhibited lower sorption/solubility than Panavia SA resin cements (both P < 0.05). The ceramic shade had a significant influence on the microhardness of both cements (P < 0.001) but had no significant effect on the sorption/solubility of resin cemenion/solubility of both cements.
To compare the rise in temperature using trephines over conventional ones during bone site preparation.

An-vitro, evaluative study.

Twenty implant sites were prepared using pilot drill up to depth of 10 mm on bovine femoral bone. In first part, no irrigation was used. Five sites were prepared using conventional drill of 2.8 mm, and other five were prepared with help of trephine drills. On completion of each drill, infrared thermometer was used to measure temperature on both the drill tip and the shaft. The same procedure was repeated with bone immersed in saline.

Student t test was used to evaluate the significance of difference.

Study showed that the temperature rise at drill tip was significantly higher for trephine drill (52.98 ± 1.67 °C) than conventional drills (48.20 ± 0.67 °C), however the temperature difference in trephine and conventional drills was statistically insignificant.

The temperature increase was more distributed in conventional drills than trephine. Copious irrigation is thus mandatory for trephine drills. Intermittent drilling is preferred with conventional drills.

The purpose of systematic review and meta-analysis was to compare the efficacy of short implant versus conventional long implant with sinus graft in patients rehabilitated for posterior atrophic maxilla.

Systematic review and meta analysis.

Electronic searches were conducted in Pub Med, Embase, and Medline with supplemented by manual search up to December 2019. The randomized controlled trial (RCTs) comparing short implant (<8.5 mm) and long implant (>8.5 mm) with sinus graft were included. (Prospero CRD42020186972).

Random-effect model, fixed-effect model, A funnel plot and the Egger's test.

Twenty-two Randomized controlled trials (RCTs) were assessed with 667 patients and 1595 implants (short implant767, Long implant835). No significant difference of implant survival rate was recorded for short and long implant (at patient level RR 1.01, 95% CI = 0.52-2.0, P = 0.87, I
= 0%, at implant level RR = 1.09, 95% CI = 0.6-2.0, P = 0.7, I
= 0%). Similarly marginal bone resorption was reported no posterior atrophic maxilla.
To systematically review the available literature on full mouth rehabilitation of the worn out dentition to help the clinician to choose a suitable philosophy to treat an individual Turner and Missirlian classification.

Systematic review following PRISMA guidelines.

The electronic search engine explored for relevant published studies from the earliest available date, from January 1960 till October 2018. Search terms included were "full mouth rehabilitation OR occlusion OR philosophies of full mouth rehabilitation OR oral rehabilitation OR Pankey Mann Schuyler philosophy OR Hobo Twin stage OR Hobo Twin Table OR worn out dentition OR Turner and Missirlian classification". All collected studies were analyzed and a total of 54 articles and 2 hand searches were extracted, among which 32 articles were selected for the systematic review. Of these 32 articles, 8 were original research studies, 23 case reports and 1 study which comprised 3 case reports were incorporated. Hence, a total of 26 case reports were coond most commonly used followed by Hobo Twin table. Maximum patients with worn out dentition are grouped under category no.1 of Turner and Missirlian classification system. Maximum cases of this category are treated by Pankey Mann Schuyler's philosophy.
Recording the maxillomandibular relationship is important in various prosthodontic treatments. Evidence of face-bow transfer resulting in improved outcome is conflicting. Hence the objective of this study is to determine the use of face-bow transfer in prosthodontics.

Systematic review based on PRISMA guidelines.">.

A protocol was developed prior, which covered all aspects of the review. The databases explored were MEDLINE database, ScienceDirect, and Cochrane collaboration library. The PICO model included participants who received a complete denture/partial denture prosthesis. Intervention was the use of the face-bow device. Comparator was prosthesis made with a simple procedure of not using a face-bow device for prosthodontic rehabilitation. Outcomes were patient satisfaction with dentures, the stability of the dentures, esthetics, and time taken for clinical and laboratory procedures. Only randomized clinical trials were included in this study. The methodological quality of the studies was assessed according to the Cochrane risk of bias tool.

Qualitative analysis.

A total of 144 articles were identified. On excluding 4 duplicates and screening the title and abstracts of the rest of the records based on exclusion criteria only 15 studies were selected for review.

The use of the face-bow did not yield superior results for the quality of the prosthesis. Therefore, there is no evidence for the utility of face-bow transfer in complete denture treatment. link2 However, no inference could be drawn for its utility in partial denture prosthodontics as there was no study to draw an inference.

The aim of this review was to evaluate the survival rate of axial and tilted implants in rehabilitation of edentulous jaws using all on four concept.

Systematic Review.

A literature review was performed in MEDLINE, PubMed Central (PMC), Google scholar, Embase, Cochrane Central Register of Controlled Trials. Hand searches were conducted of the bibliographic of related journals and systematic reviews. A total of 380 articles were obtained from the intial screening process. Of these articles, 25 articles fulfilled the inclusion criteria. The authors performed evaluation of articles independently as well as data extraction and quality assessment.

Qualitative analysis.

The major prosthetic complication was the fracture of the acrylic prosthesis. The mean cumulative survival rate of implants (72-132 months) were 94% to 98%. The prosthesis survival rate (12 months) was between 99% to 100%. The averaged bone loss was 1.3 ±0.4 mm (12-60 months). No Significant difference was found between survival rates of axial and tilted implants nor between maxilla and mandible.

All on four concept can be employed successfully in the edentulous patients with resorbed ridges while improving their quality of life and reducing morbidity. However,randomized clinical trials with large sampling size and long term follow up should be incorporated.

The cutaneous lesions were suggestive of subacute cutaneous lupus erythematosus and erythema multiforme. His clinical, histopathological, and immunological features were indicative of Rowell syndrome and he satisfied the diagnostic criteria of Rowell syndrome proposed by Zeitouni et al. He subsequently developed neurological manifestations and was diagnosed to have neuropsychiatric systemic lupus erythematosus. We report this case for the unusual occurrence of a rare entity like Rowell syndrome in an adolescent male with co-existence of neuropsychiatric systemic lupus erythematosus.
