The material groups were subdivided into 4 groups (n = 10) according to the beverage solution used to simulate aging: distilled water (control), red wine, orange juice, or soda (Coca-Cola). After 24 hours, the specimens were polished, and the initial microhardness and surface roughness were measured using a microhardness tester and profilometer, respectively. The specimens were then submerged in different beverage solutions for 4 weeks, and microhardness and surface roughness measurements were taken again. Two-way repeated-measures analysis of variance and Fisher least significant difference test were performed (α = 0.05). The aging process with different beverage solutions resulted in significantly lower hardness values compared with baseline for both Z350 XT and Acri Duralay materials (P < 0.05); however, Z350 XT still demonstrated significantly higher hardness values than all other materials regardless of the aging condition (P < 0.05). In general, Protemp 4 and Z350 XT exhibited lower surface roughness values than Structur 2 SC and Acri Duralay regardless of the solution used (P < 0.05).

Oral health deteriorates further when care is postponed, resulting in greater treatment needs when the patient visits the dental office. This retrospective study aimed to determine differ¬ences in service return rate and frequency of visits for each of 12 American Dental Association (ADA) oral procedures in patients with and without SMI who were treated in a predoctoral dental clinic at a northeastern US dental school. This retrospective study used the dental electronic health records of 12,138 adult patients aged 18 years and over (total of 19,096 unique patient encounters) who received at least 1 comprehensive oral evaluation between January 1, 2017, and August 31, 2021. Three data processing methods were implemented to retrieve periodontal diagnoses in accordance with American Academy of Periodontology guidelines and to extract medical histories and behavioral factors from free text. Chi-square tests determined that there were statistically significant differences between the 2 groups for 4 of 12 ADA procedures, while t tests deter¬mined that the SMI group had a higher frequency of visits for 6 procedure categories. Logistic regression analysis showed that patients with an SMI had a significantly higher odds ratio of receiving 2 procedure categories (remov¬able prosthodontics and adjunctive general services). A negative binomial regression analysis was then conducted to predict the frequency of visits; patients with an SMI had a higher incidence rate ratio of receiving 4 ADA procedure categories (preventive, removable prosthodontics, oral and maxillofacial surgery, and adjunctive general services). This study identified the existence of oral healthcare disparities in a population with SMI in relation to specific ADA dental procedure categories.

The present study aimed to examine the impact of a single submucosal dexamethasone injection on pain and swelling following implant placement. A total of 60 patients with at least 1 nonrestorable tooth were randomly divided into 2 equal groups and underwent tooth extraction followed by immediate implant placement. Immediately after place¬ment of the implant, suturing of the incision, and irrigation, the intervention group received a submucosal injection of 4 mg of dexamethasone, while the control group received a submucosal injection of normal saline as a placebo. The patients' self-reported pain and swelling levels were as¬sessed 2, 4, and 7 days after surgery. Pain was measured using a 10-cm visual analog scale in which 0 denoted no pain and 10 denoted the highest possible level of pain. Swelling was evaluated using a 6-point scale in which 0 denoted that the patient did not notice any swelling and 5 denoted visibly present swelling that restricted mouth opening. Patient satisfaction was evaluated 7 days after surgery using an 11-point scale where 0 denoted extremely dissatisfied and 10 denoted very satisfied. The Mann- Whitney U test was used to compare the differences in pain, swelling, and overall satisfaction between the groups over time. A value of P < 0.05 was considered statistically significant.
