In vitro studies support clinical trials showing platelet-rich fibrin-mediated local delivery of antibiotics improves outcomes in impacted mandibular third molar surgery.

Our previous clinical observations showed that platelet rich fibrin (PRF) can be used to deliver antibiotics to attenuate postoperative complications after unilaterally impacted mandibular third molar surgery (IMTMS). In order to begin understanding the mechanism involved in the beneficial effects of PRF-mediated delivery of antibiotics, studies were performed, which showed that PRF preparations containing amoxicillin/clavulanic acid or clindamycin significantly inhibited the growth of S. aureus bacteria.

Comparison of the Efficacy of the Panoramic and Cone Beam Computed Tomography Imaging Methods in the Surgical Planning of the Maxillary All-On-4, M-4, and V-4.

This study is aimed at analyzing the difference between the measurements made according to certain anatomical signs of the maxillary jaw using panoramic radiography and cone beam computed tomography (CBCT) to decide whether to use all-on-4, M-4, or V-4 configuration to prevent complications caused by incorrect measurements during the presurgical planning stage of the placement of implants in the all-on-4 technique. A retrospective study was conducted with 50 patients with upper edentulous jaws suitable for the all-on-4 technique, who underwent preoperative panoramic radiography and cone beam computed tomography evaluation for dental implant surgery. The shortest vertical distances between anatomical structures were measured.

Comparison of the Postoperative Effects of Local Antibiotic versus Systemic Antibiotic with the Use of Platelet-Rich Fibrin on Impacted Mandibular Third Molar Surgery: A Randomized Split-Mouth Study.

The surgery of the impacted mandibular third molar is the most frequent procedure in dentistry. The prescription of systemic antibiotics after the third molar extraction is widespread among dentists, but this is still argumentative. This study is aimed at evaluating the postoperative effects of local antibiotic mixed with platelet-rich fibrin (PRF) and a postoperative systemic antibiotic prescribed for mandibular third molar surgery.

Efficacy of Laser-Activated Irrigation and Conventional Techniques in Calcium Hydroxide Removal from Simulated Internal Resorption Cavities: Micro-CT Study.

This study aimed to evaluate the effectiveness of different irrigant-activation techniques for eliminating calcium hydroxide from an internal root canal resorption cavity by using microcomputed tomography (micro-CT). Several techniques and irrigants are inadequate for the complete removal of calcium hydroxide from an internal root resorption cavity. Recently, a few studies have investigated the effectiveness of various methods, but there has been no micro-CT study that compares the effectiveness of photon-induced photoacoustic streaming (PIPS) and shock wave enhanced emission photoacoustic streaming (SWEEPS) techniques.

Saliva: Both a Threat and an Opportunity in Covid-19 Pandemic.

Covid-19 pandemic, continues all over the world with the increasing number of confirmed cases and performed tests day by day. It has been shown that collecting nasopharyngeal samples, as the most commonly prefered method to perform RT-PCR, has disadvantages like causing discomfort and bleeding in patients. Sample collecting procedure also renders healthcare professionals by exposing them to the risk of transmission of the virus related to the direct contact with patients.

Comparative Evaluation of the Effects of Adenotonsillar Hypertrophy on Oral Health in Children.

We aimed to investigate the oral health of children in terms of the presence of dental caries, periodontal health, halitosis, and dentofacial changes in patients who had adenotonsillar hypertrophy related to mouth breathing and compared these findings with nasal breathing healthy and adenotonsillectomy-operated children. The patient group comprised 40 mouth-breathing children who were diagnosed with adenotonsillar hypertrophy, while the control group consisted of 40 nasal breathing children who had no adenotonsillar hypertrophy. Forty children who had undergone an adenotonsillectomy operation at least 1 year prior to the study were included in the treatment group.

In Vitro Comparison of Fluoride, Magnesium, and Calcium Phosphate Materials on Prevention of White Spot Lesions around Orthodontic Brackets.

One common negative side effect of orthodontic treatment with fixed appliances is the development of white spot lesions (WSLs) around brackets. This study is aimed at comparing the efficacy of various oral hygiene practices in preventing enamel demineralization around orthodontic brackets under similar in vitro conditions. The study included 90 extracted bovine incisors, which were randomized into six groups: fluoride toothpaste (FT), nonfluoride toothpaste (NFT), fluoride varnish plus fluoride toothpaste (FV+FT), CPP-ACP varnish plus fluoride toothpaste (CPP-ACP+FT), medical minerals gel plus nonfluoride toothpaste (MMG+NFT), and no intervention (control).

How to address a biological complication by using advanced platelet-rich fibrin during the interdisciplinary management of congenitally missing maxillary lateral incisors.

Congenital agenesis of lateral incisor is one of the most prevalent dental anomalies and is commonly treated by correcting the axes of maxillary central and canine teeth deviated toward the deficient area orthodontically, replacing the missing maxillary lateral incisor with dental implants and prosthetic restorations. Conducting treatment in interdisciplinary manner is the main criterion for the successful outcome. If this is ignored, clinicians may experience biological, mechanical or combined complications.

Effect of the application of surface treatments before and after sintering on the flexural strength, phase transformation and surface topography of zirconia.

Objectives: To evaluate the effects of airborne-particle abrasion (APA) and Er,Cr:YSGG laser irradiation on 4-point-flexural strength, phase transformation and morphologic changes of zirconia ceramics treated at pre-sintered or post-sintered stage.

Methods: Three hundred and forty-two bar shaped zirconia specimens were milled with different sizes according to the flexural strength test (n = 10), X-ray diffraction (XRD) (n = 4) and field emission scanning electron microscope (FE-SEM) (n = 4) analyses. For each test protocol, specimens were divided into 4 main groups whether the surface treatments applied before or after sintering and whether the specimens received heat treatment or not as pre-sintered, post-sintered no-heat and post-sintered heat-treated groups, and a group was served as control.

Uncommon Odontogenic Orocutaneous Fistula of the Jaw Treated with Platelet-Rich Fibrin.

Orocutaneous fistula (OCF) of dental origin is a relatively rare condition and continues to be a challenging diagnosis. Misdiagnosis of OCF usually leads to unnecessary and noneffective treatment. A 21-year-old male referred with a complaint of a lesion on the chin which was misdiagnosed as a carbuncle (lesion of nonodontogenic origin) by a physician.

Evaluation of preoperative model surgery and the use of a maxillary sinus surgical template in sinus floor augmentation surgery.

Maxillary sinus augmentation is an accepted technique for dental implant placement in presence of insufficient maxillary bone. There are various techniques in the literature, either by crestal or lateral approach in maxillary sinus augmentation that have high percentage of success, while all have complications. Schneiderian membrane perforation is the most common complication encountered during surgery.
