Filter by:Local anesthetic injection is considered one of the most annoying dental procedures. The use of topical anesthesia is considered a routine procedure in the dental clinic especially for children. However, the taste and application procedure of the topical gel may not be pleasant for all children. The introduction of the Buzzy device is considered a distraction measure in the medical field. Alanazi et al., 2019, studied the effect of using the Buzzy device with cold and vibration compared to the conventional infiltration technique using 30-gauge needle. They concluded that the use of the Buzzy device resulted in better patients' acceptance and significantly lower Wong-Baker scores. Ballard et al., 2019, mentioned in their systematic review the efficacy of the Buzzy device for pain management during needle-related procedures, they concluded that the use of the device may be promising. Ghaderi et al., 2013, evaluated the effect of cooling the injection site on pain perception before infiltration of local anesthetics. They found that cooling the injection site before infiltration of local anesthetics in the buccal mucosa for 1 min, reduced pain perceived by pediatric patients.
This triple-blind, randomized clinical trial was conducted at the department of Operative dentistry. A total of 60 participants were recruited and were randomly distributed into two groups A and B. After informed consent, restorative treatment was performed. In group A, adhesive with nanoparticles was used for composite restoration while in group B, adhesive without nanoparticles was utilized. Post-operative sensitivity was recorded using VAS score.
A more biological and conservative technique of caries removal has emerged with minimally invasive restorative dentistry's advent. As a result, Smart Burs II has become a self-limiting, sensitive tool for removing caries. The current study aimed to validate and contrast the polymer burs' efficacy (Smart Burs II) versus conventional burs (Carbide burs) for infected carious dentin's selective removal in permanent first molars. Thirty permanent first molars fulfilling the inclusion criteria were chosen in 8-11 years old children with class I occlusal carious lesions. Group 1 (n=15) and Group 2 (n=15) were randomly assigned to have carious dentin removed utilizing standard carbide bur and a smart Bur II, consecutively. By employing caries detector dye, the effectiveness of caries removal was quantified as 0, 1, 2, 3, 4, or 5. The volume of removed carious tissue was recorded using impression material which was inserted into a calibrated insulin syringe. A statistically significant difference was discovered in the volume of removed carious tissue between both groups, while the efficiency of caries removal using either bur has no significant difference. Smart Bur II was more conservative in the carious dentin's removal than carbide bur. Smart Bur II was as efficient as carbide bur in caries removal.
Pharmacokinetic (PK) study of L-arginine after exaggerated oral use of the novel dentifrice product COL101 after repeated daily applications in healthy adult subjects.
The goal of this clinical trial was to explore how adding Tulsi extract, a natural plant substance, to chewing gum affects the levels of Streptococcus mutans, type of bacteria that cause dental caries, in the saliva of children aged 4 to 11 years. Participants should not use removable prosthetics or orthodontic appliances and had had not used antibiotics in the 2 weeks preceding sample collection. We want to answer this main question: Can chewing gum with Tulsi extract significantly reduce the number of Streptococcus mutans bacteria in children's saliva? Participants tasks: - Children were asked to chew gum containing Tulsi extract for 5 minutes and then dispose of the gum. - Two salivary samples were collected from each child: one before gum chewing and another 30 minutes after disposing the gum. Researchers compared Streptococcus mutans counts in saliva before and after gum chewing to determine if there is a significant reduction in bacterial colonies.
Space maintainers are frequently used to prevent malocclusion problems in early primary tooth loss. Oral health literacy is defined as the capacity of individuals to learn, understand and evaluate basic oral health information. It is considered that parents' awareness of space maintainers may be affected by various factors such as their demographic characteristics and oral health literacy. The aim was to evaluate the relationship between variables by determining parents' awareness of space maintainers and their oral health literacy.
This study (a double-blinded, prospective, randomized clinical trial) aimed to evaluate 2-year clinical performance of dual- and light-cure bulk-fill resin composites in Class ӀӀ restorations. The null hypothesis tested in this study was that, there would be no difference in the 2-year clinical performance of all tested bulk-fill resin composites in Class II restorations. Forty patients were enrolled in the study. Each patient received three bulk-fill resin composites Class ӀӀ restorations. One dual-cure and two light-cure bulk-fill resin composites were used for Class ӀӀ restorations following manufacturer's instructions. A universal adhesive was used with all restorations. All restorations were clinically evaluated after 1 week (baseline), 6 months, 12 months, 18 months and finally after 24 months using the FDI World Dental Federation criteria.
This study will pilot a school-based stakeholder-informed hydration intervention and examine its feasibility and preliminary efficacy.
This study aimed to evaluate the clinical performance of a novel, tooth-colored, self-adhesive bulk-fill restorative, and a conventional bulk-fill composite, for restoring class II cavities.
The study's null hypothesis posits no significant difference in bacterial levels in the dental office environment before and after implementing hydrogen peroxide (H₂O₂) fumigation. The study comprised 30 participants, 18 females and 12 males, all diagnosed with moderate caries decay (ICDAS 3 and 4) in their mandibular molars, averaging 42.2 ± 8.3 years in age. Sample size calculations for 30 microbiological plates in each group utilized G*Power software (Kiel University, Germany), factoring in prior research, with a significance level of 0.05, effect size (d) of 0.72, 95% confidence interval, and 85% power. Aerobic bacterial content in the dental office air was assessed using the Koch sedimentation method. The study employed 60 Petri dishes with Columbia Agar and 5% Sheep Blood. During caries treatment, thirty plates were opened and sealed 40 minutes later, while another set of thirty plates was opened and closed 60 minutes post-fumigation. Measurements were taken 1 meter above the ground and 2 meters from the patient's mouth. After 48 hours of incubation at 37°C, microbiological contamination was calculated as CFUs (colony-forming units) in one cubic meter using the formula: L = a × 1000 / (πr² × k). Fumigation involved a 20-minute treatment with 6% hydrogen peroxide biosanitizer (Saniswiss, Switzerland) via a compressed air device (Fumi-Jet, Kormed, Poland). The process included 3 minutes of fumigation and a 17-minute waiting period for the chemotoxic effect, with 45 ml of 6% hydrogen peroxide sprayed in a 20 m² room.
