Effectiveness of pre-injection use of cryoanesthesia as compared to topical anesthetic gel in reducing pain perception during palatal injections: a randomized controlled trial.

Background: Palatal injections are often painful. We aimed to compare topical ice and 20% benzocaine gel for pre-injection anesthesia before greater palatine nerve block (GPNB) injections. Methods: A randomized split-mouth clinical trial was conducted among patients aged 15-60-years needing bilateral GPNB injections. A total of 120 palatal sites from 60 patients were randomly allocated to Group A (topical ice) or Group B (20% benzocaine gel). Pain was evaluated using sound, eye, motor (SEM), and the visual analog scale (VAS) in both groups. Inferential analysis was performed using the Mann-Whitney U test. Results: The mean age of the participants was 20.5 ± 3.9 years. The median VAS score for group A was 11 (Q1 - Q3: 5.25 - 21.75), which was slightly higher than the 10 (Q1 - Q3: 4.0 - 26.75) reported in group B. However, the difference was not statistically significant (P = 0.955). The median SEM score for group A and group B was 3.5 (Q1 - Q3: 3.0 - 4.0) and 4.0 (Q1 - Q3: 3.0 - 4.0), respectively, which was statistically insignificant (P = 0.869). Conclusion: Using ice as a form of topical anesthetic for achieving pre-injection anesthesia before GPNB was as effective as 20% benzocaine gel.

Maxillofacial Injuries in an Eastern Nepal Tertiary Hospital.

BACKGROUND: Maxillofacial injury is a major health problem, and injury patterns vary in different societies. The purpose of the present study was to evaluate the pattern of maxillofacial injuries presenting to BPKIHS. METHODS: Patients with age >15 years presenting with maxillofacial injuries from May, 2019 to April, 2020 were included in this cross-sectional descriptive study. Demographic profile, etiology, delay in presentation, pattern of soft tissue/ bony/ dental injuries, treatment modality were recorded and analyzed using Microsoft excel. RESULTS: Within one year study period 190 patients with age group >15 years presented with facial injuries. There were 164 male (86.32%) and 26 female (13.68 %) patients (M:F=6.3: 1) with mean age of 34.96 years. Road Traffic Accident (RTA) (61.58%) was the most common etiology. Majority of the patients reported to hospital within 2-6 hrs of injury. Other associated injuries was present in 36.32 % of patients with orthopedic injury (60.87%) being common. Soft tissue injuries were seen in 80.53% patients, of which 49.02% were associated with facial fractures. Mandible fractures were seen in 56.19% of hard tissue injuries, of which 40.68% had multiple fractures followed by 28.81% with parasymphysis fracture. Within 37.14% patients with midface fractures, zygoma fracture (33.33%) was the commonest. Intervention was done in 80.95 % patients, with ORIF (72.38 %) being the commonest. Dentoalveolar injuries was seen in 22.63 % patients, of which 48.19% were associated with facial fractures. CONCLUSIONS: Our observations show that motor vehicle accidents were the most frequent cause of maxillofacial injury.

Tension orbit secondary to a carious primary molar-A case report.

Though rare, a pediatric dentist should have background knowledge of this kind of presentation which can greatly affect their patient's quality of life and leave them with a significant deficit at a very young age.
