Here, we review the current knowledge on PHB physiology together with a summary of recent findings on novel functions of PHB in stress resistance. Vorinostat cell line Potential applications of these new functions are also presented…

To analyze the loss of nonvital abutment teeth compared to vital abutment teeth supporting removable partial dentures (RPDs).

An electronic search was conducted in the Ovid MEDLINE, Embase, and Web of Science databases, and supplemented by a manual search. The search was done to identify clinical studies reporting the loss of nonvital abutment teeth compared to vital abutment teeth for RPDs. The data were extracted from each selected article and meta-analysis was performed using a random effects model to estimate adjusted proportion of abutment loss with RPDs along with 95% confidence interval (CI). Risk of bias assessment was conducted using Cochrane Risk of Bias tools and Newcastle-Ottawa Scale. The statistical significance was set as P value < .05.

A total of 3,898 records were identified from electronic databases and 8 studies were included for quantitative synthesis of 834 subjects with 1,036 RPDs. No additional records were identified through manual search. Among 1,152 nonvital abutment teeth, research is needed to identify critical factors associated with the loss of nonvital abutment teeth.

Within the limitations of this systematic review and meta-analysis, the loss of nonvital abutment teeth was significantly greater than that of vital abutment teeth for RPDs. Further research is needed to identify critical factors associated with the loss of nonvital abutment teeth.

The purpose of the present study was to present vertical ridge augmentation (VRA) with the use of cross-linked resorbable membrane, tenting screws, and a combination grafting technique.

Three cases are presented. Case 1 A 67-year-old ASA II patient required VRA at the areas of the mandibular left second premolar and first molar. Flap management was performed with the use of periosteal release on the buccal aspect and 23 mm of mylohyoid muscle release on the lingual aspect. VRA was completed with the use of four self-tapping tenting screws, and 11 mix of anorganic bovine bone matrix (ABBM) and particulate mineralized bone allograft. A cross-linked resorbable membrane was placed over the buccal and lingual aspect, and a double line of suturing was performed to secure the tension-free closure. Twelve months postoperatively, 4 mm of VRA was confirmed with CBCT. Two implants were placed with >35 Ncm primary stability. Case 2 A 64-year-old ASA I patient required VRA at the area of the maxillary first premola5.3 mm of bone regeneration on the vertical dimension and 3.9 mm on the horizontal dimension. An implant was placed with primary stability of 45 Ncm.

Successful VRA can be achieved with proper flap management to achieve tension-free closure, a cross-linked collagen membrane, tenting screws, and a combination grafting technique. The VRA ranged from 4.0 to 7.9 mm.

To monitor and compare the nonsubmerged (single-stage, SS) and submerged (two-stage, TS) implant placement techniques up to the final prosthesis delivery. Marginal bone level and marginal bone loss rate of both surgical techniques were compared.

Marginal bone level was measured, using an image processing program (ImageJ), from periapical radiographs at the times of placement (T0), exposure (Te), initial loading (T1), and at the final prosthetic delivery (T2), with a total time span of a mean of 13.2 ± 3.3 months. By timing normalization, marginal bone level and marginal bone loss rate (mm/month), following SS and TS implant placement techniques and other local and systemic parameters were analyzed. Asymmetric analyses using Mann-Whitney test followed by the correlation Pearson analyses were applied. A P value < .05 defined statistical significance.

In total, 268 implants (42 patients) were monitored. Marginal bone loss rate was 0.15 ± 0.13 mm and 0.13 ± 0.11 mm, between T0 and T2, for the SS and TS toking, bruxism, anatomical location, and interproximal implant distance apparently affect the marginal bone level and marginal bone loss rate of both implant placement approaches. The implant placement surgical mode, combined with various systemic and/or anatomical factors could play a significant role in maintaining marginal osseous level around the implant neck.

The opioid crisis is devastating rural America, but findings of opioid utilization vary among previous studies. Previous studies were focused on misuse behaviors or overdose issues. This study will focus on the number of pills and prescriptions that rural and urban adults received.

Using the adult data of the 2011-2016 Medical Expenditure Panel Survey, we compared rural-urban differences in likelihood of using opioids and actual utilization. Multivariate models were further adjusted for predisposing, enabling and need factors.

During 2011-2016, opioid utilization decreased in both urban and rural areas. However, rural adults were still more likely to have a prescription, and among users, rural adult prescription pill count was higher than urban counterparts. The rural-urban difference was not significant after adjusting for covariates, indicating that personal and contextual characteristics account for more variations in utilization than rurality.

Strategies to improve pain management without causing hare medication with others and safely dispose of unused pills; (2) reinforcing the mail-back program or giving patients a specially-designed package to neutralize the drugs; and (3) if a community-based drug-disposal program is not available, educating to remove labeling from the bottle, mix the drugs with an unpleasant substance, and place the drugs and unpleasant substance in the garbage separate from the bottle. The findings of adjusted analyses indicate that another study will be helpful to explore the associations between personal characteristics and opioid utilization in depth.
