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.
背景:采用锥束ct (cone beam computed tomography, CBCT)比较一旋转式(XP-endo Shaper)和两旋转式(one Reci和Reciproc Blue)单文件系统预备后下颌磨牙危险区域的牙本质厚度。材料与方法:选择具有2个独立根管的下颌第一磨牙近中根36颗。提供初始CBCT扫描后，根据所使用的单个锉将牙齿分为3组:XP-Endo Shaper (XPS)， One Reci (OR)和Reciproc Blue (RB)。在使用各自的单一文件系统进行准备后，再次扫描根文件。在CBCT扫描中测量了危险区域的最小牙本质厚度，即在分叉水平以下4,5,6和7mm。初始和最终测量值用于计算危险区域内去除的牙本质厚度。资料采用重复测量方差分析(p=0.05)。结果:两组牙本质厚度差异无统计学意义(p>0.05)。结论:所评估的单锉系统在下颌磨牙危险区域的切割效果相似。

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.

Osteomyelitis is defined as the inflammation of the either medullary, cortical, or cancellous bone, including nerves and blood vessels, causing necrosis and bone sequestrum formation; this condition has become a rare pathology, and odontogenic infections are considered the most frequent causal factor. This case shows a patient with bi-maxillary osteomyelitis caused by Actinomyces spp, which was worsened for severe COVID-19 infection. Patient was submitted at surgery as, amplified total bilateral maxillectomy through the surgical technique Weber-Fergusson, and prolonged use of combination of antibiotics, achieved a good recovery. Two years later follow-up, the patient no show imaging or clinical evidence of the infection of osteomyelitis. The present case shows an interesting relationship between a rare infection and its association with COVID-19.

Kron harabiyeti fazla olan kök -kanal tedavili molar dişlerin restorasyonunda, direkt ve indirekt restorasyonlar dahil olmak üzere farklı konvansiyonel tedavi seçenekleri bulunmaktadır. Endokronlar, intraradiküler post, kor ve kronu tek bir parçada birleştiren monoblok yapıda olan, geleneksel post -kor restorasyonlara alternatif olarak ortaya çıkmış güncel tedavi seçeneğidir. Marjinal ve internal uyum, protetik restorasyonların uzun dönem başarısını etkileyen en önemli faktörlerdendir. Restorasyonların marjinal uyumu yetersiz olduğu durumlarda, zamanla siman çözünmesine bağlı olarak diş ile restorasyon arasında oluşan boşluk bakteri ve yiyecek artıkları ile dolar. Bu da plak birikimi, çürük ve periodontal problemlere sebep olmaktadır. Bilgisayar destekli tasarım/ bilgisayar destekli üretim (CAD/CAM) sistemi ile daha iyi marjinal ve internal uyuma sahip restorasyonlar elde edilmektedir. CAD/CAM sistemlerinde görülen gelişmeler sonucu endokron restorasyonların kullanımını yaygınlaşmıştır ve başarılı protetik sonuçlar elde edilmektedir. Bu derlemenin amacı endokron restorasyonlar ve bu restorasyonların marjinal ve internal uyumları hakkında bilgi vermektir.

The objective of this study is to determine the impact of oral conditions on the quality of life related to the oral health of preschool children in a rural and urban area of Cusco. The study was descriptive and cross-sectional, from a population of 179 preschoolers aged 3 to 5 years, from two public early childhood education institutions, and their respective parents or caregivers in the department of Cusco, Peru. We worked with the entire population that met the inclusion and exclusion criteria, seventy-four preschool children were selected for each area, deciding to have the same amount of children per group based on the smallest group. A clinical odonto-stomatological examination was carried out for oral conditions (dental caries, malocclusion, and dental trauma) according to the WHO’s criteria and a survey that was used for sociodemographic characteristics. In addition, a validated Peruvian version of the ECOHIS questionnaire was used to obtain data on the impact on quality of life. All the variables of the total and individual scores of the ECOHIS domains were analyzed individually and the Kruskal-Wallis test was used to determine the association between variables. The oral conditions prevalence in preschool children in rural areas referring to dental caries was 100% (dmft index > 6), dental trauma 10.8%, and malocclusions 60.8%; for the urban area dental caries was 93.2% (dmft index > 6), dental trauma 9.5% and malocclusions 36.5%. Of the three oral conditions only the experience of dental caries was related to the OHRQOL of preschoolers in urban and rural areas.

To evaluate the microtensile bond strength (µTBS) of two resin cements to 3D printed and milled CAD/CAM resins used for provisional fixed partial dentures. Blocks (5 x 5 x 5 mm) of three 3D-printed resins (Cosmos3DTemp / Yller; Resilab3D Temp / Wilcos and SmartPrint BioTemp, / MMTech) were printed (Photon, Anycubic Technology Co.). A milled material (VitaCAD-Temp, VITA) was used as control. Half the specimens were sandblasted and the rest were untreated. Two blocks were bonded with the corresponding resin cement: PanaviaV5 (Kuraray Noritake) and RelyX Ultimate (3M Oral Care). After 24 hours, the bonded blocks were sectioned into 1 x 1 mm side sticks. Half the beams were tested for µTBS and the other half was thermocycled (5000 cycles, 30s dwell-time, 5s transfer time) before µTBS testing. A four way Generalized Linear Model (material*sandblasting*cement*aging) analysis was applied. VITA exhibited the lowest µTBS, regardless of the cement, sandblasting and thermocycling. Sandblasting significantly improved the µTBS of VIT, especially after aging, but did not improve the µTBS of 3D printed resins. Sandblasting was not beneficial for 3D printed resins, although is crucial for adhesive cementation of milled temporary resins. Airborne particle abrasion affects the integrity of 3D-printed resins, without producing a benefit on the microtensile bond strength of these materials. However, sandblasting is crucial to achieve a high bond strength on milled temporary resins.
