Dental Specimen Preparation Protocol

The roots were carefully purified from calculus, biofilm, and soft tissues using an ultrasonic scaler (Sinius; Sirona Dental Systems, Bensheim, Germany); occlusal surfaces (in particular, the carious areas) were excluded from sonicating to prevent lesion surface breakdown. After placing all teeth into an ultrasonic bath (Elmasonic S 130 H; Elma Schmidbauer, Singen, Germany) for 25 min, the crowns were cleaned by means of a rotating prophylactic brush (CleoProphy Brush, spiky; Zhermack, Marl am Dümmer, Germany) and prophylactic paste (Cleanic, fluoride-free; Kerr, Bioggio, Switzerland) for 10 s. Using this approach, the surfaces were cleaned without any damage. Subsequently, the teeth were carefully rinsed with an air/water sprayer (Sinius; Sirona Dental Systems, Bensheim, Germany) for approximately 20 s to eliminate all paste, powder, and (non-)natural deposit residues. Finally, all occlusal surfaces were thoroughly dried with compressed air for 30 s (Sinius; Sirona Dental Systems, Bensheim, Germany), and photographs of all teeth were taken (EOS 450 D, Macro Ring Lite MR-14 EX; equipped with a Macro Lens EF 100 mm, 1:2.8 USM; Canon, Tokyo, Japan). Until further examination, the teeth were stored in isotonic saline (0.9% sodium chloride solution; in-house production) using a storage box (Hornbach, Krems an der Donau, Austria) at room temperature.

Long-term Photographic Monitoring of Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Digital photographs of the samples were taken at day 0 and then after 1 and 3 months. After the three-month incubation period, the samples were removed from the incubator and then exposed to ambient light for a further 24 months. They were maintained in their original clear plastic containers on a shelf in a glass-panelled room at a room temperature of 24-30°C and with relative humidity from 40-55%. Although they were exposed to diffuse and indirect sunlight, there was no direct sunlight on the samples at any point. Samples were photographed after 1, 3, 6, 9, 12, 16 and 24 months. The photographs were taken under standard conditions - that is, the same distance from the camera to the samples (25 cm) and the same background (white paper) with a CMYK colour calibration standard included in each image. A digital camera (Mark II EOS 5D, Canon, Tokyo, Japan) was fitted with a 105 mm macro lens and a ring flash (Macro Ring Lite MR-14EX). The same settings were used for all exposures.

Blinded Clinical Evaluation of Dental Implants

Check if the same lab product or an alternative is used in the 5 most similar protocols
All patients were recalled for baseline, and 1‐, 3‐ and 5‐year follow‐up examinations, and the clinical trial ended after the last follow‐up as the quality control of treatments was completed 5 years from the prosthetic treatment was performed. The clinical and radiographic assessments were blinded and performed by one observer, who was not involved in the treatment of the patients. Clinical photographs of the restorations, including the neighboring teeth and marginal peri‐implant mucosa, were taken by using a digital camera (Canon EOS450D, Canon) with a macro lens flash (MACRO RING LITE MR‐14 EX, Canon) at all follow‐up examinations. Digital intraoral radiographs (Digora® Optime digital films, Soredex, Tuusula, Finland) were obtained by using long cone paralleling technique with Eggen’s film holders at each follow‐up examination, and were assessed using the Digora Optime system. Biological, technical and aesthetic variables were registered at all examinations. Trial outcome measures were not changed after the trial commenced.

Insect Specimen Documentation Workflow

Check if the same lab product or an alternative is used in the 5 most similar protocols
A stereoscopic microscope Leica MZ12 and a light source Leica KL 1500 LCD were used for optical examination. The measurements were done with an ocular micrometer.
Photographs of whole insects or different body parts were taken with a Canon EOS 400D Digital camera and a Canon Macro Ring Lite MR-14EX flash device. Detailed multi-focus photographs of the diagnostic characters were taken with a Leica DFC 490 Digital camera on a Leica Z16Apo stereoscopic microscope using Leica Application Suite Version 4.5.0 and merged with Helicon Focus 5.3.14.
The digital drawings were produced with the use of a graphical tablet (Wacom Intuos5 Touch M), Adobe Photoshop CS4 (Version 11.0.2) and Adobe Illustrator CS4 (Version 14.0.0), as described by Coleman (2003) .
The species key was generated using DELTA (Version 1.02).
All maps were created with QGIS (Version 2.0.1-Dufour) and the use of Google Earth (Version 7.1.2.2041). The political map of Australia was downloaded from www.naturalearthdata.com.
Images were edited and cleaned of dirt using Adobe Photoshop CS6, Version 13.0.1 and Adobe Illustrator CS6, Version 16.0.1.
The “material examined” section was formatted using the AutoMatEx spreadsheet (Brown 2013 (link)) and Microsoft Excel 2010.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
