“…Higher PLS may enable the greater killing of residual bacteria when composites are used for minimally invasive tooth restorations. Considering the limitations of this study and taking into account work completed in previous studies [24][25][26], future research should include sucrose in the experiments to allow for biofilm growth on the discs to determine the effectiveness of PLS against biofilms, test multispecies biofilms and assess long term polylysine release and how this may affect the integrity of the restoration.…”

The study aim was to assess the effect of incorporating polylysine (PLS) filler at different mass fractions (0.5, 1 and 2 wt%) on PLS release and Streptococcus mutans planktonic growth. Composite containing PLS mass and volume change and PLS release upon water immersion were assessed gravimetrically and via high-performance liquid chromatography (HPLC), respectively. Disc effects on bacterial counts in broth initially containing 8 × 105 versus 8 × 106 CFU/mL Streptococcus mutans UA159 were determined after 24 h. Survival of sedimented bacteria after 72 h was determined following LIVE/DEAD staining of composite surfaces using confocal microscopy. Water sorption-induced mass change at two months increased from 0.7 to 1.7% with increasing PLS concentration. Average volume increases were 2.3% at two months whilst polylysine release levelled at 4% at 3 weeks irrespective of composite PLS level. Early percentage PLS release, however, was faster with higher composite content. With 0.5, 1 and 2% polylysine initially in the composite filler phase, 24-h PLS release into 1 mL of water yielded 8, 25 and 93 ppm respectively. With initial bacterial counts of 8 × 105 CFU/mL, this PLS release reduced 24-h bacterial counts from 109 down to 108, 107 and 102 CFU/mL respectively. With a high initial inoculum, 24-h bacterial counts were 109 with 0, 0.5 or 1% PLS and 107 with 2% PLS. As the PLS composite content was raised, the ratio of dead to live sedimented bacteria increased. The antibacterial action of the experimental composites could reduce residual bacteria remaining following minimally invasive tooth restorations.

“…One thing that can be done to prevent hypersensitivity reactions from SSC is to carry out a comprehensive history taking if the patient is going to perform restorations with dental materials that can trigger an allergic reaction. This can prevent unwanted reactions from occurring [33,34]. Patch-skin tests can also be done before performing restoration treatment.…”

Tooth structure damage is usually caused by tooth decay or external damage. Dental fillings are one of the restorative dental treatments used to repair tooth fractures, tooth decay, or damage to tooth surfaces. Dental fillings include composite, porcelain, and silver amalgam, which are used on the tooth surface for better biting and chewing. The aim of this literature review is to assess the merit of stainless-steel crown, the shortcoming of stainless-steel crown, and the hypersensitivity reaction and dental management against hypersensitivity reaction of stainless-steel crown. The method used in this study was by reviewing international journals related to hypersensitivity reaction against stainless-steel crown. The results of this literature review showed that stainless-steel crown had advantages such as good physical properties, less sensitivity to moisture, and less prone to fracture; nevertheless, it had disadvantages such as unstable in acid pH and drastic change of temperature, which led to the release of a metal ion such as nickel into the oral cavity and the emergence of hypersensitivity reaction. The treatment that can be done for hypersensitivity reaction was by doing a patchskin test before treatment and restoration replacement with non-toxic material. This review can be applied as a consideration on determining restorative treatment, especially in pedodontics restorative treatment.

“…81.8% of students prefer composite over amalgam and the rest 18.2% don't prefer (Table-1), compared to previous studies, more percentage of respondents prefer composite over amalgam. 25 54.5% students think that, there is the relation between mercury released from dental amalgam and neurological diseases, 27.3% don't think that and the rest 18.2% are not aware (Table -3). Currently, there is no evidence that dental amalgam causes any severe neurological diseases.…”

Usage of proper dental restorative materials is very important in dentistry. One who is doing the course of dentistry should have sound knowledge on these restorative materials. Furthermore, it is important to know the view of budding young dentists about safety of dental restorative materials. The aim of present study was to assess the awareness and perception of undergraduate dental students towards safety of dental restorative materials. A study was carried out by using multiple-choice structured questionnaire among 262 students, the questionnaire was prepared in such a way that we can assess the attitude, their perception and awareness towards safety of dental restorative materials. The data was collected and statistically analysed. Although, most of the participants were having moderate level of awareness towards safety of dental restorative materials. The level of perception of some respondents towards amalgam related and other restorative materials related issues was found to be improved, participants with a better perception and attitude are having more knowledge and awareness towards safety of dental restorative materials. Within the limitations of the study, usage of alternative materials to amalgam should be improved.
