Gram-negative bacteria include more than 20 genera. The most commonly isolated genera are: Bacteriodes spp., Porphiromonas spp., Fusobacterium spp. and Prevotella spp. The following genera were isolated somewhat less frequently: Tanerella spp., Leptotricha spp., Veilonella spp.,Wollinela spp., Selenomonas spp. and Treponema spp. Anaerobic bacteria have an anaerobic type of metabolism and therefore their incubation is significantly longer and more demanding than aerobic bacteria. The genera Prevotella spp., Porphyromonas spp. and Fusobacterium spp. are part of the resident flora of the oral cavity and in unfavorable conditions cause periodontal diseases, and sometimes dentogenic infections and systemic diseases, such as Alzheimer?s disease, cardiovascular diseases, metabolic diseases and inflammatory bowel diseases. The three most important steps for the successful diagnosis of anaerobic bacteria are: proper sampling with avoiding sample contamination, rapid transport of samples to the microbiological laboratory and proper handling of samples. A combination of beta-lactam with the addition of beta-lactamase inhibitors, metronidazole, clindamycin and moxifloxacin is used for treatment for infections caused by anaerobic Gram-negative bacteria. It is important to note that antibiotics should be used only with a clear indication and to choose the right antibiotic in the optimal dose. The aim of this review is to point out the role of Gram-negative anaerobic bacteria in periodontal diseases, and its isolation, identification and antibiotic susceptibility.

Introduction. The aim of this work was to check the average thickness of dentinal wall of the mesio-buccal root of the first lower molar using CBCT axial sections of intact teeth. Material and method. In this cross-sectional study, 100 CBCT images of mandibular first molars from the Promax 3Dent radiology center in Banja Luka, Bosnia and Herzegovina were evaluated. A Planmeca Promax3D Max apparatus (Planmeca, Helsinki, Finland) was used, with a field of view (FOV) of 8 ? 8 cm and a resolution of 0.1 mm. Analysis was performed using Romexis Viewer software version 3.1.1 (Planmeca, Helsinki, Finland). At an axial thickness of 0.1 mm, transverse sections with a distance of 1 mm were made below the furcation area (at a magnification ?10) at a distance of 1, 2, 3, 4, 5 mm from the furcation. The data were then analyzed by paired t-test. Results. The thickness of dentinal wall of the mesio-buccal root of the lower first molar was significantly smaller at 2 mm and 3 mm than when measured at 1, 4 and 5 mm (p < 0.05). There was no significant difference between measurements at 1, 4 and 5 mm below the furcation area (p = 0.001). Conclusion. Due to the small thickness of dentinal wall at 2-3 mm below the furcation in the root canal, caution is required when instrumenting mesio-buccal canal of the lower first molar and correct selection of the instrumentation technique in order to avoid transportation or stripping perforation that may lead to root fracture.

Introduction. Mandibular canal with the associated neurovascular bundle may be closely related to the apices of mandibular teeth. In order to avoid injuries and damages to the inferior alveolar nerve during invasive dental procedures, it is important to know its localization. The aim of this study was to determine the average vertical distances of the root apices of second premolars, first molars and second molars mesially and distally from the upper projection of the mandibular canal on the sagittal section of CBCT images, and determine if there were statistically significant differences between the age and gender groups. Material and methods. The research was conducted at the Faculty of Medicine of the University of Banja Luka, and the sample consisted of 146 CBCT images of patients. CBCT images were obtained using Planmeca ProMax 3D Mid instrument (Planmeca, Helsinki, Finland) and analyzed using Planmeca Romexis Viewer software. In the sagittal section, the vertical distance from the root apex to the upper projection of the mandibular canal was measured for each examined tooth. Results. The distal root of the first molar (4.88 mm) had the greatest average vertical distance of the root apex from the mandibular canal, and the distal root of the second molar had the smallest average vertical distance (2.76 mm). There was statistically significant difference between certain age groups in the values of individual roots, for the second molar mesially and distally (p < 0.05), while for the first molar mesially the value of p was at the limit of significance (p = 0.05). Conclusion. The results of this study showed that distal root of the mandibular second molar had the smallest vertical distance from mandibular canal, therefore an extra caution during a root canal treatment and careful planning of oral surgery in this region is recommended.

Introduction. A risk of transmission of infectious diseases has always been an inherent part of dental practice. Easily communicable respiratory and blood borne diseases have prompted dental communities to establish, evaluate, update and monitor infection prevention and control (IPAC) protocols and strategies (guidelines). The aim of this paper was to present Canadian standard protocols of infection prevention and control in dental offices, and compare them with similar guidelines available to dentists in Serbia. Method. A detailed overview of the most current IPAC guidelines and protocols provided by the College of Dental Surgeons of British Columbia in Canada has been summarized. In addition, the effect of the most recent Covid-19 pandemic on the current infection prevention and control measures in dental offices and future perspectives has been reviewed. Conclusion. Implementing infection prevention and control guidelines is essential part of practicing dentistry. Regulatory authorities have responsibility to establish and provide dentist with the most current IPAC protocols while dentists need to adopt up-to-date procedures and appropriately and consistently use them in everyday practice.
