Diabetes mellitus is a systemic condition potentially related to an increased risk of progression of various infections such as chronic osteomyelitis by accelerating the inflammatory process with bone tissue necrosis and suppuration. Therefore, if there is no proper management of these infections, they can be life-threatening as they spread to deeper spaces in the head and neck. We describe the case of a 52-year-old male patient with a history of diabetes mellitus and grade III osteoarthritis who was diagnosed with chronic suppurative osteomyelitis of the mandible. He underwent a multidisciplinary surgical intervention in which he underwent a hemimandibulectomy with immediate mandibular reconstruction. The present case highlights the importance of early and radical treatment of patients with chronic suppurative osteomyelitis of the mandible and systemic comorbidities. In addition, this case presents a review of diabetes mellitus and the risk of developing odontogenic infections and complications when invading deeper spaces in the head and neck. Therefore, in this population, careful planning is required for early surgical and pharmacological treatment.

The present study aims to identify the empathic attitude of dental students from a Peruvian public university, about their reading habits, as well as the level of studies and other sociodemographic variables. 226 first-, fourth-, and sixth-year students registered in the academic year 2022 were enrolled in the study. The Jefferson Empathy scale, which included 20 items, was used with a Likert scale ranging from 1 to 7, i.e., from totally disagree to totally agree. A file containing questions about the sociodemographic data registry was prepared together with the Jefferson Empathy questionnaire. It was found that the profile of the students was mainly feminine, and the average age was 22 years; they came from Lima. They had the habit of reading and a little more than half of the group did not participate in sports activities. The "adequate" level of empathy was the highest (51.77%). By dichotomizing the response variable, it was found that adequate empathy was related to the habit of reading, especially reading dental books. Dental students from this public university mostly have an adequate level of empathy; it is independent of the sociodemographic variables but is related to reading habits.

Ectodermal dysplasia (ED) is a genetic disorder affecting anatomical structures with an ectodermal origin. The consequent alveolar bone anomalies and lack of teeth require a multidisciplinary approach to rehabilitate patients function and esthetics. To avoid bone grafting procedures the application of zygomatic implants was suggested for the upper jaw treatment. The advancements in three-dimensional (3D) radiology and the introduction of digital implant planning software could enhance the approach to zygomatic implants in ED patients. The present case report describes the quad zygomatic implant treatment of the edentulous maxilla of an ED patient by means of computer guided implant surgery. The patient reported previous failure of bone grafting procedures in the upper jaw. The implants were immediately loaded with a screw-retained complete-arch resin prosthesis. The patient was followed up for 1 year with no biological nor mechanical complications reported, but a slight bone resorption in the anterior zone was observed. Zygomatic implants could be a potential alternative treatment to bone grafting in upper jaw and the digital implant planning could enhance the surgical procedure.

The purpose of this study was to examine the effect of different decontamination agents on the bond strength of saliva-contaminated CAD/CAM blocks and repair composite materials. Two hunderd eighty 3-mm-thick specimens were prepared from four different CAD/CAM materials: Katana Zirconia UTML disc, IPS e.max CAD block, Shofu block, and Vita Enamic block. Each material was divided into seven different subgroups (N=70). Group 1 had a clean surface. The other groups were comprised of the samples, which were contaminated with human saliva: group 2: negative control (non-cleaned); group 3: cleaned with water spray; group 4: cleaned with 70% ethanol; group 5: cleaned with Ivoclean; group 6: cleaned with Katana Cleaner; and group 7: cleaned with phosphoric acid. After the decontamination protocols, the resin composite cylinders were bonded to the CAD/CAM surfaces with a thin layer of dual-cured resin cement. The samples were stored for 24 hours at 37°C in distilled water. Then, they were subjected to a shear bond strength test (SBS). The values were recorded, and fracture types were evaluated using a microscope. Data were analyzed using two-way ANOVA and Tukey’s post-hoc test. Generally, all decontaminating agents improved the SBS of composites to Katana Zirconia UTML, IPS e.max, and Vita Enamic materials (p<0.05). However, for Shofu materials, group 6 samples exhibited significantly higher bond strength values as compared with group 2 samples (p=0.026). The highest SBS values were seen in the phosphoric acid-treated group in Katana zirconia materials (26.45 ± 9.38 MPa), whereas the lowest values were seen in group 2 samples in Shofu materials (13.17 ± 3.40 MPa). Each decontaminant agent improved the bond strength of composites to the contaminated CAD/CAM materials. If saliva is not cleaned before adhesive procedure, SBS values may decrease. All decontamination agents can be used safely on zirconia, lithium-disilicate glass-ceramic, hybrid ceramic, and polymer-infiltrated ceramic surfaces.

Işıkla polimerize olan restoratif materyallerin diş hekimliğinde yer edinmesiyle birlikte kullanılan ışık kaynaklarının da önemi artmıştır. Reçine esaslı kompozitler, reçine modifiye cam iyonomer simanlar, kompomerler, fissür örtücüler, geçici dolgu materyalleri ve sayamadığımız birçok restoratif materyalin polimerizasyonu ışık ile sağlanmaktadır. Polimerizasyonun başlaması için bir başlatıcıya ihtiyaç vardır. Bu başlatıcıya fotoinitatör denir ve bu fotoinitatörlerin aktivasyonu için de ışık kaynağı gereklidir. Kullanılan ışık kaynağının fotoinitatörlerin absorbsiyon spekturumuna uygun olması gerekmektedir. Aksi takdirde spektral uyumsuzluk meydana gelecek ve bu uyumsuzluk durumunda yeterli düzeyde aktifleşemeyen fotoinitatörler polimerizasyon sürecini tam olarak gerçekleştiremeyecektir. Bu bağlamda diş hekimlerinin kullandıkları malzemelerin içeriklerine dikkat etmeleri, üreticilerin de malzemelerine dâhil ettikleri başlatıcıları belirtmeleri oldukça önemlidir. Çünkü polimerizasyon eksikliği, yapılan restorasyonun klinik başarısını olumsuz yönde etkiler. Yetersiz polimerizasyon aşınma direncinin düşük olmasına ve restorasyonun zayıf mekaniksel özellikler göstermesine neden olmaktadır. Ayrıca monomer yapının polimer yapıya dönüşümünün tam olarak gerçekleşememesi ile birlikte artık monomer miktarında belirgin bir artışın meydana gelmesi pulpa dokusu üzerinde toksik etkilerin oluşmasına sebep olabilmektedir. Bu derleme çalışmamızda polimerizasyon sürecinden ve bu sürecin başlamasını sağlayan fotoinitatörlerden bahsedilecektir. Günümüz dolgu materyalleri içerisinde sıklıkla ihtiva eden başlatıcılardan olan kamforokinon, TPO (2,4,6-Trimethyl benzoyl diphenyl phosphine oxide), PPD (1-fenil-1,2-propandion) ve son zamanlarda yeni çıkan ve bazı ürünlerde bulunan Ivocerin®’in özellikleri anlatılacaktır. Bu fotoinitatörlerin absorbsiyon spektrumları ile tek ve çift pikli LED (light-emitting diode) ışık cihazlarının spektral aralıkları karşılaştırılıp, grafiksel olarak gösterilecektir.

Background: To compare the dentin thickness in the danger zone of mandibular molars after preparation with one rotating (XP-endo Shaper) and two reciprocating (One Reci and Reciproc Blue) single file systems using a cone beam computed tomography (CBCT). Materials and Methods: Thirty-six mesial roots of mandibular first molars having two independent canals were selected. After initial CBCT scans were provided, teeth were assigned into 3 groups related to the single file used: XP-Endo Shaper (XPS), One Reci (OR) and Reciproc Blue (RB). The roots were scanned again after preparation with respective single file systems. The minimum dentine thickness in the danger zone, at 4, 5, 6 and 7 mm below the furcation level, were measured in CBCT scans. Initial and final measurements were used to calculate the removed dentin thickness in the danger zone. Data was analyzed using Repeated-measures ANOVA (p=0.05). Results : No significant differences were found related with remaining and removed dentin thickness among single file systems at any level from the furcation (p>0.05). Conclusions: The evaluated single file systems showed similar cutting efficiency in the danger zone of mandibular molars.

This research evaluates the presence of the oxygen-inhibited layer (OIL) on the top surface of a photopolymerized dental composite resin protected with a glycerin layer. This evaluation was conducted using physical and mathematical methods. Polymerized discs were fabricated to evaluate Vickers microhardness (VHN), and pre-and post-polymerized samples were used for the calculation of C-O/C-H ratios through Fourier Transform Infrared Spectroscopy (FTIR) (n=10), using two types of glycerin, one for medical use (MG) and another for dental use (DG). Surface hardness decreased from MG to DG to CO, and the increase in C-O/C-H ratios decreased in the same order (p<0.05). Samples protected with medical and dental glycerin layers are harder and exhibit lower C-O/C-H bond ratios than the control group.

The objective of this research was to identify bacteria present in the microbiota of dentinal carious lesions in primary molars of some Costa Rican pediatric patients. Data were collected from 15 children aged between 4 and 8 years old who attended the Pediatric Dentistry Clinic at the Faculty of Dentistry from the University of Costa Rica (UCR). The inclusion criteria were: infants between 4 and 8 years old who presented cavitated carious lesions in primary teeth, who were actively attended by students at the Faculty of Dentistry from the UCR, and whose parents or legal guardians signed the informed consent to participate in this research. Samples were taken using a sterile spoon, placed in storage vials, and subjected to various conventional and molecular microbial identification techniques, such as Gram stain identification, catalase tests, oxidase, TSI, API 20E, API STAPH, and VITEK 2. Of the 60 bacterial strains subjected to Gram staining, the following was obtained: 28 Gram-positive bacteria and 32 Gram-negative bacteria. The main isolated organisms were species of Staphylococcus epidermidis, Pasteurella pneumotropica/Mannheimia haemolytica, Pantoea spp, and Streptococcus mutans.
