A mixture of polyvinylpyrrolidone and 1,2-indanedione (PVP-IND) is known to be the best reagent for developing latent fingerprints deposited on the surface of a thermal paper. However, no study has evaluated whether PVP-IND could enhance fingerprints in blood deposited on the surface of thermal paper. Therefore, in this study, the ability of PVP-IND to enhance the fingerprints in blood was investigated. Furthermore, aqueous amido black solution, which is known to be the best reagent for enhancing fingerprints in blood deposited on the surface of thermal paper, was used for comparison with PVP-IND. Therefore, while enhancing the fingerprints in diluted blood, PVP-IND enhanced the quality of fingerprints compared to aqueous amido black solution. The ridge diffused when the undiluted fingerprints in blood were enhanced with PVP-IND because PVP reacted with amino acids in blood; however, amido black solution yielded better results. When treated with PVP-IND, it is presumed that the ridge diffused due to the reaction of PVP and amino acids contained in the blood.

Oral mucocele is a common exophytic lesion resulting from the accumulation of saliva due to pathological changes in the minor salivary glands. It is typically asymptomatic and painless and characterized by semipermeable, fluctuant nodules. General treatment methods for mucocele include surgical excision, marsupialization, cryosurgery, and steroid injection. This case report presents the treatment of oral mucocele using micro-marsupialization and a tying method as minimally invasive techniques rather than surgical treatment. Based on this case report, it is suggested that micro-marsupialization and the tying method can be used as alternative methods for the treatment of oral mucocele infants and children with behavioral control problems.

With the development of digital dentistry, it is being applied in various ways of dental treatment. This case report presents the definitive prosthesis designed in advance with a re-established vertical dimension and the digital technology, which determined the amount of tooth preparation, in order to preserve as much tooth structure as possible in a patient with pathological wear of the posterior teeth and loss of vertical dimension. For accurate tooth preparation, the guides of the occlusal and axial surfaces were digitally and additively manufactured. Then, aesthetics and anterior guidance were established at the provisional stage. The information of the provisional restoration was delivered to the definitive stage by double scanning. The digital technology, including the virtual planning and the guided tooth removal, produced the definitive restorations satisfactory to both the patient and clinician.

Installation of dental implants at optimal angles and positions is critical in long-term stable implant-supported restorations. Surgery and prosthodontic procedures should be performed accurately as the treatment is planned. In this clinical case, Computer aided design and manufacturing technology was used not only to establish a precise surgical plan, but also to fabricate both provisional and definitive fixed prostheses. A surgical guide was designed to install the implants at proper positions for the definitive prostheses. The patient's esthetic information, which was necessary for the new provisional and definitive fixed prostheses, was obtained from the existing temporary dentures. Finally, the complete mouth fixed implant-supported rehabilitation using monolithic zirconia provided the patient with functionally and esthetically satisfactory prostheses.

The effect of washing fingerprints deposited on glass that were contaminated with a flammable liquid (gasoline, kerosene, diesel, and thinner) was studied by washing with hexane or heptane. The fingerprints were visualized using fuming cyanoacrylate, followed by basic yellow 40 staining. After comparing the washing effect, by dividing one fingerprint into four sections, it was confirmed that the ridge detail was damaged by dissolving the fingerprints in flammable liquid. As a result of washing fingerprints contaminated with flammable liquids using hexane or heptane, fingerprints contaminated with gasoline, kerosene, and thinner did not show a washing effect because the ridge detail was damaged at the time of contamination, and only fingerprints contaminated with diesel exhibited improved ridge detail quality. Because hexane and heptane washing damage the ridge detail, it was found that fingerprints contaminated with gasoline, kerosene, and thinner were better enhanced directly without the washing process. In addition, it was found that the amount of the washing solvent and contact time should be minimized when washing fingerprints contaminated with diesel.

The effect of ethylenediamine (EDA) on the reaction of luminol or Bluestar with blood and bleaches was studied. For this purpose, blood, chlorine bleach, and oxygen bleach were applied to filter paper, treated with EDA-containing luminol or Bluestar, and the changes in chemiluminescence intensity were observed. It was found that the chemiluminescence intensity of the luminol (or Bluestar)-blood reaction did not change with the increasing concentration of EDA. However, the chemiluminescence intensity of the luminol (or Bluestar)-chlorine bleach reaction decreased and the chemiluminescence intensity of the luminol (or Bluestar)-oxygen bleach reaction increased, with increasing EDA concentration. Thus, it was found that when EDA was added to luminol (or Bluestar), which is a blood-sensitive reagent, EDA suppressed the false-positive reaction induced by chlorine bleach and induced a false-positive reaction with oxygen bleach. Consequently, the addition of EDA is not recommended for enhancing bloodstains with luminol or Bluestar.
