This following report is unique due to the complexity of his existing maxillary dentition being restored with a combination of removable and fixed prosthodontics and the location of the fracture occurring within the esthetic zone. Furthermore, the patient's complex medical history and severe gag reflex added additional factors to the rehabilitation of this patient.</p><p>A 64-year-old Caucasian male presented to the General Practice Residency with fracture of his fixed partial denture (#9-11). Patient's maxillary arch was restored previously using FPD #6-8 and #9-11 with a Kennedy Class I removable partial denture. Opposing dentition was restored with all ceramic zirconia crowns. Secondary caries noted on fractured #11 deemed non-restorable and #9 fractured equigingival with fair prognosis for restoring via NSRCT, post, core and crown. History of Myocardial Infarction within past year and severe gag reflex. Impressions for this patient required the use of intravenous moderate procedural sedation. Consultation with PCP and cardiologist for medical clearance for moderate sedation were obtained and patient was appointed for impressions, records, and extraction of #9 and #11. Patient was offered plans including traditional denture fabrication, implant retained, or implant fixated prosthesis.

The goal of this project was to evaluate the in vitro properties and antiviral activity of a prototype aqueous EC16 nanoformulation.</p></div><div><h3>METHODS</h3><p>Nanoparticles of EC16 were obtained by a natural-forming method. Nanoparticle size and Zeta potential were measured by the ZetaView Nanoparticle Tracking Analysis (NTA) system. The pH and viscosity of the formulations were measured.

The model was modified to extract tooth #8 digitally in the Blue Sky Bio® software. Surgical guides were designed to extend from tooth number 6 to 10. Forty guides were printed with Formlabs Form 3B+ printer and Formlabs surgical guide resin following manufacturer's instructions. Each guide was scanned with Prime Scan optical scanner before disinfection and sterilization. Twenty guides were individually packaged, and autoclave sterilized at manufacturer's recommendation of 134°C for 20 minutes. The remaining twenty guides were soaked in 70% isopropyl alcohol for fifteen minutes. After sterilization and disinfection, the guides were scanned and STL files from pre- and post-sterilization were compared in GeoMagic Control X software to examine dimensional changes. A paired T-test was done to evaluate distortion of the guide before and after sterilization and disinfection. An unpaired T-test was done to compare the disinfection and sterilization test groups.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;RESULTS&lt;/h3&gt;&lt;p&gt;The average deviation at the lingual, incisal, buccal, combined surfaces, and the entire guide of the sterilized group was 6.28μm, -2.4μm, -20.6μm, 5.6μm, and 12.6μm respectively. The average deviation at the lingual, incisal, buccal, combined surfaces and the entire guide of the chemically disinfected group was -0.43μm, 2.6μm, -0.78μm, 0. μm, and 5.5μm respectively. Paired T-test of the sterilized group showed a significant difference before and after sterilization at all surfaces with p-values &lt;0.05. Paired Ttest of the disinfection group showed no significant difference before and after chemical disinfection at any surface. Unpaired T-test between the sterilized and disinfected group showed a non-significant difference between the incisal and total averages. There was a statistically significant difference between the average deviation of the lingual surfaces with a p-value of 6.31763E-06, the buccal surface with a pvalue of 3.83055E-13, and the combined surfaces with a p-value of .0001.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;CONCLUSIONS&lt;/h3&gt;&lt;p&gt;Results indicate that there is distortion after sterilization and minimal distortion with chemical disinfection.

A flowable resin composite (3M™ Filtek™ Supreme Flowable Restorative, A2) was used as control. Using PVS, molds were made from custom 3D-printed models measuring 6.0mm in diameter and 2.0mm in height.

The exact etiology of LJSGH has not been established, but trauma and orthodontic treatment have been proposed as possible causes. The aim of this review article is to identify etiologies of this condition and report evidence of which factors are most closely associated with LJSGH.</p></div><div><h3>METHODS</h3><p>A systematic literature search of the databases Pubmed, EMBASE, and Google Scholar through December 2023 was conducted. 215 subjects across 30 case series/studies were included and a descriptive analysis of data concerning patient demographics, clinical presentation, and treatment was conducted. Prevalence of potential etiologic contributors was also noted.</p></div><div><h3>RESULTS</h3><p>The review yielded 215 subjects, 110 males (51.2%) and 105 females (48.8%). The age was reported in 135 participants, with a mean age of 14.9 (Median= 12, SD= 11.14). Lesions were solitary in 94.0% of the cases (n= 202) and 86% of the cases (n=197) occurred on the maxilla, with 93.4% (n= 214) of lesions affecting the anterior portions of the gingiva. The facial surface of the gingiva was involved in 90.8% of the cases (n=208). The most common treatment for LJSGH was surgical excision (71%, n=87) followed by biofilm control and observation (13.9%, n= 17).
