Does Liquid/Injectable Platelet-Rich Fibrin Help in the Arthrocentesis Treatment of Temporomandibular Joint Disorder Compared to Other Infusion Options? A Systematic Review of Randomized Clinical Trials.

Temporomandibular joint disorders (TMDs) are prevalent musculoskeletal conditions involving pain and dysfunction of jaw mobility and function, which have proven difficult to treat satisfactorily. The present study aimed to assess the effectiveness of a liquid platelet-rich fibrin (i-PRF) infusion during arthrocentesis versus other options using coadjuvant materials to reduce TMD symptoms. A literature search was conducted using PubMed, EMBASE, Web of Science, Scopus, and ClinicalTrials.gov for RCTs published before January 2024, comparing i-PRF to any other TMD treatment. This systematic review was registered on PROSPERO (CRD42023495364). The searches generated several recent RCTs that compared i-PRF injection combined with arthrocentesis (AC) to AC-only or AC with platelet-rich plasma (PRP). The outcomes analyzed included measures of pain (visual analog scale, VAS), maximum mouth opening, joint sounds, and MRI-verified changes in joint structure. Across the RCTs, the addition of i-PRF injection to AC resulted in significant improvements in pain relief, joint function, mouth opening, and structural changes compared to AC-only or with PRP over follow-up periods ranging from 6 to 12 months. Current clinical evidence favors using i-PRF as an adjunct to AC rather than AC-only or AC with PRP for the treatment of TMDs. The improvements in subjective and objective outcome measures are clinically meaningful. Still, additional high-quality RCTs with larger sample sizes and longer follow-ups are required to strengthen the evidence base and better define the role of i-PRF in TMD management guidelines.

What are the emerging trends in dental composite materials in permanent teeth with occlusal cavities: self-adhesive vs traditional?

DESIGN: The research is a systematic review and meta-analysis of randomized controlled trials (RCTs). AIM: The study aimed to compare the clinical outcomes of self-adhesive flowable composite resins (SAFCs) versus conventional flowable composite resins (FCs) used in occlusal cavity restorations in permanent teeth. METHODS: This research included a search for RCTs. Multiple databases were systematically searched for RCTs with a minimum 1-year follow-up comparing SAFCs to FCs. Outcomes evaluated were retention, secondary caries, marginal adaptation, marginal discoloration, and postoperative sensitivity based on modified USPHS criteria. Risk of bias was assessed using Cochrane RoB 2 tool. Random effects meta-analyses were conducted where applicable. Certainty of evidence was rated using GRADE approach. RESULTS: Five RCTs (four parallel and one split mouth) comprising 138 patients were included. During 1- and 2-year recalls, there were generally no significant differences in clinical performance between SAFCs and FCs. However, FCs applied using the etch-and-rinse technique demonstrated statistically better marginal adaptation at 2 years (3 studies, RR 3.21, 95% CI 1.50-6.83) and marginal discoloration (4 studies, RR 3.40, 95% CI 1.10-10.48). The overall quality of evidence ranged from low to moderate. CONCLUSIONS: SAFCs showed comparable short-term outcomes to FCs in treating occlusal cavities. Further high-quality RCTs with longer follow-up are warranted to confirm long-term performance of SAFCs. Use of separate enamel etching may improve marginal adaptation and discoloration with FCs.

Is it possible to decrease the occurrence of dental implant failures through the use of preventative antibiotics?

DESIGN: The research was a randomized placebo-controlled clinical trial evaluating the use of clindamycin as a preoperative medication to prevent the dental implant. AIM: The purpose of the study was to assess if giving a single dose of 600 mg oral clindamycin 1 h before a conventional dental implant procedure could reduce the risk of early implant failure and post-surgical complications in healthy adults. METHODS: A clinical trial was conducted with ethical standards, utilizing a randomized, double-blind, placebo-controlled approach. Healthy adults who required a single oral implant and had no previous surgical site infection or need for bone grafting were enrolled. Before surgery, participants were given either oral clindamycin or placebo at random. A single surgeon performed all operations, and patients were observed by a trained professional on multiple postoperative days. The study considered early dental implant failure as the loss or removal of an implant. Clinical, radiological, and surgical data were analyzed statistically to identify group differences. The number of subjects needed to treat, or harm, was calculated. RESULTS: The research involved two groups of 31 patients each: the control group and the clindamycin group. Two patients in the clindamycin group experienced implant failures (NNH = 15, p = 0.246). Three patients in the study had postoperative infections; two of them were from the placebo group, while one from the clindamycin group had an unsuccessful treatment outcome. The relative risk was 0.5, with a CI of 0.05-5.23 and an absolute risk reduction of 0.03. The confidence interval was -0.07-0.13, and the NNT was 31, with a CI of 7.2-∞ and p = 0.5. In addition, only one patient treated with clindamycin reported gastrointestinal disturbances and diarrhea. CONCLUSIONS: There is no conclusive evidence to suggest that administering clindamycin prior to oral implant surgery in healthy adults reduces the risk of implant failure or post-surgical complications.

Dental needs and conditions of individuals with Lowe syndrome: An observational study.

INTRODUCTION: Lowe syndrome (LS) is an uncommon condition that affects the brain, kidneys, nervous system, and eyes, predominantly in males. The aim of this study was to examine dental conditions, dental treatments, and access and/or barriers to care for those with LS compared to healthy individuals. METHODS: Surveys assessing dental conditions, dental treatments, and access and/or barriers to care were administered to families in the Lowe Syndrome Association and families with healthy children who had dental appointments at the Tufts University School of Dental Medicine (TUSDM) pediatric dental clinic. One parent or a guardian of pediatric patients with LS or not at TUSDM was asked to complete an online survey. RESULTS: One hundred and eight surveys were obtained (n:58 from the LS group and n:50 from the healthy group). The LS group was significantly more likely (p < .05) to report "crooked/misaligned teeth," "difficult time chewing," "bad breath," and "mouth cysts" and was significantly less likely to report 6-month examination, "cleaning," and "filling." The LS group reported significantly greater difficulty locating a dentist. CONCLUSION: The findings of this study indicate that individuals with LS are more vulnerable to developing severe dental conditions and experiencing difficulties in accessing dental care than healthy individuals. Additionally, those who present with this syndrome may be less likely to receive specific necessary dental treatments. As a result, it is essential to offer appropriate dental care and support to individuals with LS to guarantee they achieve optimal oral health.

Harnessing the Power of PAOO and Invisalign: An Interdisciplinary Approach to Orthodontic Care.

The present article explores the benefits of combining periodontally accelerated osteogenic orthodontics (PAOO) with Invisalign for optimal orthodontic treatment outcomes. PAOO is an interdisciplinary dental technique that minimizes complications and accelerates tooth movement while enhancing various orthodontic treatments. In conjunction with Invisalign, PAOO provides a discreet and comfortable solution for patients seeking to improve their smile. The study presents two challenging cases successfully treated using this combined approach, emphasizing the technique's potential to reduce treatment times and improve orthodontic outcomes. The interdisciplinary approach of PAOO ensures long-term success and stability by preserving periodontal structures and addressing potential bony defects. By incorporating bone grafting materials, PAOO helps prevent common concerns in traditional orthodontic treatments, such as bony defects and gingival recession. Furthermore, the combination with Invisalign offers a more aesthetically pleasing and comfortable treatment experience, allowing patients to maintain their self-esteem and confidence throughout the treatment. Despite the potential advantages, dental professionals must manage patient expectations and address potential complications to ensure the best possible results. Overall, the integration of PAOO and Invisalign demonstrates a viable alternative for patients who do not want to proceed with orthognathic surgery, enhancing patient satisfaction and overall treatment outcomes.

Standardization of Animal Models and Techniques for Platelet-Rich Fibrin Production: A Narrative Review and Guideline.

Experimental research is critical for advancing medical knowledge and enhancing patient outcomes, including in vitro and in vivo preclinical assessments. Platelet-rich fibrin (PRF) is a blood by-product that has garnered attention in the medical and dental fields due to its potential for tissue regeneration and wound healing. Animal models, such as rabbits and rats, have been used to produce PRF and examine its properties and applications. PRF has demonstrated potential in the dental and medical fields for reducing inflammation, promoting tissue repair, and accelerating wound healing. This narrative review aims to compare existing evidence and provide guidelines for PRF animal research, emphasizing the importance of standardizing animal models, following ethical considerations, and maintaining transparency and accountability. The authors highlight the necessity to use the correct relative centrifugal force (RCF), standardize centrifugal calibration, and report detailed information about blood collection and centrifuge parameters for reproducible results. Standardizing animal models and techniques is crucial for narrowing the gap between laboratory research and clinical applications, ultimately enhancing the translation of findings from bench to bedside.

Comparing the Long-Term Success Rates of Tooth Preservation and Dental Implants: A Critical Review.

Implant therapy is considered a predictable, safe, and reliable rehabilitation method for edentulous patients in most clinical scenarios. Thus, there is a growing trend in the indications for implants, which seems attributable not only to their clinical success but also to arguments such as a more "simplified approach" based on convenience or the belief that dental implants are as good as natural teeth. Therefore, the objective of this critical literature review of observational studies was to discuss the evidence concerning the long-term survival rates and treatment outcomes, comparing endodontically or periodontally treated teeth with dental implants. Altogether, the evidence suggests that the decision between keeping a tooth or replacing it with an implant should carefully consider the condition of the tooth (e.g., amount of remaining tooth and degree of attachment loss and mobility), systemic disorders, and patient preference. Although observational studies revealed high success rates and long-term survival of dental implants, failures and complications are common. For this reason, attempts should be made to first save maintainable teeth over the long-term, instead of immediately replacing teeth with dental implants.

Clinical Assessment of Biphasic Calcium Phosphate in Granules and Paste Forms in Human Maxillary Sinus Bone Augmentation: A Randomized, Split-Mouth Clinical Trial.

The aim of the present study is to compare the biphasic calcium phosphate (BCP) using two different forms-(1) granules and (2) paste-in human maxillary sinus bone reconstruction as a split-mouth study using histomorphometric and immunolabeling for osteocalcin. Ten patients with bilateral maxillary posterior partial edentulism were selected in order to reconstruct bone height. They were divided into two groups: BCPG and BCP-P. After six months of bone healing, biopsies were harvested to assess the new bone formation and immunostaining for osteocalcin. The BCP g group had the following results: mean of bone formation in pristine bone 49.4 ± 21.6%, intermediate 49.4 ± 16.2%, and apical 55.3 ± 21.4%. The group BCP-P had a mean of 41.9 ± 17.3% in the pristine bone region, 37.5 ± 7.8% for intermediate, and 39.0 ± 13.5% for apical. The osteocalcin immunolabeling was high for both groups, demonstrating bone calcification. Thus, the two biomaterials present suitable results for the placement of dental implants.

Control of postoperative pain with a wearable continuously operating pulsed radiofrequency energy device: a preliminary study.

BACKGROUND: Pulsed radiofrequency energy (PRFE) has long been reported to have a therapeutic effect on postoperative pain. In this study, a portable, wearable, low-energy-emitting PRFE therapy device was used to determine the control of postoperative pain after breast augmentation surgery. METHODS: The study enrolled 18 healthy women who underwent breast augmentation purely for aesthetic considerations. Postoperative pain after surgery was assessed with a 0- to 10-point visual analog scale (VAS). Baseline pain scores were taken at completion of the operation, and the patients were randomly assigned coded PRFE devices that were either active or placebo devices. For 7 days, VAS scores were recorded twice daily (a.m. and p.m.). Medication use also was logged for 7 days. The PRFE devices were left in place and in continuous operation for the 7 days of the study. RESULTS: All the patients tolerated the PRFE therapy well, and no side effects were reported. The VAS scores for the active group were significantly lower on postoperative day 1. By day 7, the baseline VAS remaining in the active group was 7.9% versus 38% in the placebo group. Together with lower VAS scores, narcotic pain medication use was lower in the patient group that received PRFE therapy. CONCLUSION: Postoperative pain is significantly lower with PRFE therapy. According to the findings, PRFE therapy in this form is an excellent, safe, drug-free method of postoperative pain control.

Ambulatory alveolar bone grafting.

BACKGROUND: Traditional practice for alveolar cleft closure requires postoperative hospital convalescence in an unfamiliar, disruptive hospital setting. An outpatient iliac crest alveolar bone grafting protocol was devised to optimize patient care. METHODS: A retrospective review of the senior author's experience over 5 years (1998 to 2004) of ambulatory alveolar cleft closure was compared with the previous 5-year period (1993 to 1998) of inpatient convalescence. An iliac crest donor site and standard techniques of alveolar grafting were followed in both groups. Although local analgesia with lidocaine and epinephrine was used in both groups, the ambulatory group received preemptive local anesthesia augmented with Marcaine. Postoperative nausea also was treated preemptively in the outpatient group with the addition of dexamethasone (Decadron) and ondansetron (Zofran), whereas the control patients were treated as needed. Patient charts were reviewed for demographic information, technical aspects, length of donor-site incision, bone graft volume, and time of operation. A Fisher's exact test was used for statistical analysis. Complications including morbidity, readmission, and reoperations were recorded. RESULTS: Twenty consecutive patients were treated on an outpatient basis. Eight consecutive patients were convalesced as inpatients in the previous 5-year period. The ambulatory series average patient age was 12.1 years (range, 8 to 15 years). Four bilateral procedures were performed. The follow-up period averaged 3.5 years (range, 5 to 76 months). Two minor complications were identified: cellulitis at a donor site and a recipient suture line dehiscence with minor graft exposure. There were no readmissions, revision operations, hernias, wound infections, or graft losses identified. In the inpatient series, the average stay was 1.8 days (range, 1 to 3 days). One gingival suture line dehiscence requiring no further intervention was identified, for an average complication rate of 12.5 percent, which was not significant compared with the ambulatory group (10 percent) (p = 1.00). CONCLUSIONS: Alveolar cleft bone grafting using the iliac crest donor site can be safely performed on an outpatient basis when local pain control is followed by predictable anesthetic recovery and sufficient oral intake, and reliable motivated parents or caregivers provide a comfortable postoperative setting. Safe outpatient surgery provides patients and family the opportunity to recover in the familiar home environment.
