Aim: Orthodontists could be exposed to different occupational risks and be affected by different pathologies such as Musculoskeletal Disorders (MSDs). Prevention strategies are required to identify risk factors at different levels. Through an objective clinical evaluation, this study aimed to identify the factors related to the presence of MSDs in a group of orthodontists from Medellín (Colombia). Methods: A cross-sectional study was conducted. A clinical evaluation, focused on orthodontics-related occupational aspects, was carried out by an occupational health practitioner, that was standardized for research purposes. Sociodemographic and clinical variables were collected. Descriptive and bivariate analyses were conducted on the prevalence of MSDs according to the study variables and Chi-square tests was carried out to observe statistically significant differences. Ethical approval was obtained. Results: The prevalence of MSDs was 58.7% (95%CI 44.3- 71.7). The frequency of Upper body MSDs was 45.7% (Females: 51.4%) and in the case of Spine Area MSDs was 23.9% (Males: 45.5%). The prevalence of MSDs was higher in males, those people ≤ 44 years, Single/Separate, from middle socioeconomic status, with other medical previous conditions. Labor conditions were related to the presence of MSDs. The agreement percentage in the case of Upper body MSDs and Clinical Spine Area MSDs considering positive cases was 50% and 29.2% respectively. Conclusions: The orthodontists participating in the study manifested various MSDs and other pathologies related to their professional practice. Sociodemographic and clinical factors were related to the presence of MSDs. Epidemiological surveillance systems in occupational health and strategies in health and safety at work are requested.

Malignant bone tumors are rare malignancies of which osteosarcomas are the most common considering bone marrow tumors are excluded. They account for approximately 6-10% of jaw lesions and affect the mandible more often than the maxilla. A review of literature shows there are rare cases of osteosarcomas reported in the maxilla; however, given the lack of specific signs and a diverse range of radiographic features, the diagnosis is often difficult and requires a multidisciplinary discussion. This is the case report of a 56-year-old female presenting a well-defined, dome-shaped firm swelling with radiographic features of extensive destruction of the buccal cortical bone in the maxillary right posterior region. Early diagnosis helped in the better prognosis of the patient. She is undergoing regular follow-ups to ensure no recurrences of this aggressive lesion. Osteosarcoma of the jaw is difficult to diagnose and manage due to the high frequency of errors in biopsy results, the few specific radiological characteristics, and difficulties in appropriate resections because of the proximity to vital structures. Through the years, the survival of patients has greatly improved, due to an aggressive systemic approach and refined surgical and reconstructive techniques. However, for purposes of management, emphasis should be laid on the aggressiveness of this lesion which warrants an early identification and diagnosis of the lesion followed by prompt treatment.

A disparity between host defense and periodontopathogens leads to periodontitis, which is an inflammatory disease of the periodontium of high prevalence. The dysregulated host immune response brought on by the disease’s ongoing progression may result in tissue and bone destruction, which ultimately leads to tooth loss. Interpretation of bone metabolism has enhanced as a result of the identification of sclerostin and its function as a bone mass regulator. Primarily, osteocytes express sclerostin, an SOST gene known to inhibit formation of bone. The canonical Wnt pathway involved in bone homeostasis, is significantly suppressed by Sclerostin. It is thought to result in resorption of bone by altering the ratio of OPG and RANKL. Characteristics, mode of action and significance of sclerostin in periodontal diseases are discussed in this review.

INTRODUCTION; The treatment of Periodontal disease in Diabetic subjects should also focus on lowering blood glucose levels, which might act as an adjuvant to conventional Periodontal treatment. In the form of Probiotics, Bacterial therapy offers a dual role in controlling blood glycemic levels and reducing colonization of oral bacteria. This study aimed to evaluate the efficacy of probiotics in managing Periodontitis among Diabetic and Non-Diabetic subjects. METHODOLOGY; This study was designed as a randomized, double-blinded clinical trial among Diabetic and Non-diabetic subjects with Periodontitis. Twenty-four subjects in each Diabetic and non-diabetic group were randomly assigned into two probiotic test sub-groups and one placebo sub-group. Lactobacillus fermentum MCC2760 and Bifidobacterium longum NCIM5684 probiotic chewing gums were provided to subjects in test groups to use twice a day for 30 days. Supragingival plaque samples were collected at baseline and 30 days to analyze total bacterial count and subgingival plaque for P.gingivalis, A.actinomycetemcomitans through qPCR. Clinical parameters were recorded at baseline, 30, 45, and 90 days. RESULTS; After 30 days, a significant reduction in PI, GI, PPD, and Gingival bleeding Index was observed in SRP and SRP+Probiotic groups. There is a significant reduction in total bacterial count among probiotic groups compared to placebo. PCR analysis revealed non-significant reduction of p.gingivalis and A.actinomycetemcomitans in test groups. Intergroup comparison between Diabetic and Non-diabetic groups did not show any significant differences either in clinical or microbial parameters. CONCLUSION; Probiotic functional foods can be delivered as an adjunct to SRP to manage Periodontitis in systemically compromised subjects. Long-time use of probiotics is recommended to maintain the recolonization of bacteria in periodontal tissues.

Intramuscular hemangioma occurs in less than 1% of soft tissue hemangiomas. It is equally prevalent in men and women. In this study, we examined a case of a masseter muscle hemangioma with evidence of a suspected parotid sialolithiasis. A 24-year-old woman with a 3-year history of swelling and mild pain in the cheek and ear area was referred to our Department. Before the sialography, ultrasound imaging (sonography) was performed as an initial examination. Due to the calcification in the anterior region of the masseter muscle observed in earlier CT images, sialography was scheduled for the differential diagnosis of sialolithiasis. Sonograms showed a complex tubular mass of 20 × 35 mm in the anterior region of the masseter muscle. The mass appeared hyper vascular on color Doppler ultrasound, confirming its vascular nature. Due to its proximity to the facial nerve, a diode laser was adopted for treatment. Since intramuscular hemangiomas do not regress spontaneously and can be mistakenly diagnosed as parotid gland tumors or sialolithiasis, correct diagnosis is essential. Sonography can help with this.

Objective: The aim of this study was to evaluate the effect of both the same polishing method and those with and without thermal aging on the surface roughness of conventional, CAD/CAM milling and 3D printing denture base materials.
Materials and Methods: A total of 30 round shaped specimens were obtained by 3 different methods (n=10): Conventional, CAD/CAM milling and 3D-Printing. After applying the same polishing technique to all groups, surface roughness values were measured. Profilometer device was used for surface roughness measurement. Then, after the thermal aging of all samples, surface roughness values were measured and the roughness values between no-thermocycling and thermocycling were compared. Tukey, Mann Whitney U and Kruskal Wallis tests were used statistically. P values of ≤ 0.05 were considered significant.
Results: As a result of the same polishing process, there was a difference in surface roughness in all groups. While the highest surface roughness values were seen in 3D-printing, the lowest roughness value was seen in the CAD/CAM milling and was statistically significant (p<0.05). Thermocycling did not show a statistically significant difference in surface roughness (p>0.05).
Conclusions: The same polishing process caused different surface roughness values in the denture base materials obtained with different methods, and the lowest surface roughness value was seen in the CAD/CAM milling.

Objectives: The aim of this study was to evaluate the effect of food-simulating liquids (FSLs) and thermal aging on the surface roughness and color stability of bulk-fill and conventional composites. Materials and Methods: A total of 320 disc-shaped samples were prepared, with 40 samples from each of 4 different bulk-fill composites (Filtek Bulk Fill, X-tra fil, Beautifil Bulk Restorative, and Estelite Bulk Fill Flow), and 4 conventional nano-filled composite resins (Filtek Z550, CeramX SphereTEC one, Admira, and Kalore). The prepared samples were randomly divided into subgroups for exposure to FSLs (ethanol, heptane, citric acid) and thermal cycling (TC) (n=10 per subgroup) for 28 days. Initial profilometric surface roughness measurements (Ra0) of all samples and AFM and SEM analyses of selected samples were followed by exposure to FSLs and TC. After completion of aging protocols, measurements and analyses were repeated to obtain the Ra1 (post-treatment surface roughness), and change in surface roughness (∆Ra1-0) was then calculated. Subsequently, initial color measurement of the samples was conducted using a spectrophotometer, followed by immersion of the samples in a coffee solution for 24 hours. Color measurements were repeated, and color change (∆E) was calculated. Two-way repeated measures ANOVA was used to compare Ra0 and Ra1 values and one-way ANOVA for comparing ∆Ra and ∆E values. Tukey and post hoc tests were employed for pairwise comparisons. The significance level was set at α=.05. Results: While the surface roughness of bulk-fill composites was affected by the protocols applied (p<0.05), conventional composites generally remained unaffected. Bulk-fill composites exhibited greater ΔRa and ∆E values. The highest ∆Ra and ∆E values were observed in the Beautifil Bulk Restorative group, with the greatest discoloration seen after immersion in citric acid. Conclusions: Thermal cycling and immersion in FSLs affect surface roughness and color stability of composite resins depending on the content and structure of the composites.

АBSTRАCT: Background: The ability of the retrograde filling material to adhere to dentin has a substantial impact on the success of endodontic procedures. the marginal adaptation of the rᴏᴏt end filling materials considered important factor, since it demonstrates the materials adaptation to the dentinal walls. Objective: Assess the marginal adaptation of Biᴏ-C reparative materials in contrast to MTA (АNGELUS) and Amalgam. Material and method: A total of thirty human maxillary central incisors teeth that each had a single root were chosen. To keep the root canal length at 15mm, the crown was resected. The teeth underwent endodontic treatment, along with the resection of their root ends and preparation of root-end cavities. On the basis of the type of filling, the teeth were categorized into one of three groups, as follows: (А) Bio-C repair (Bioceramic reparative material), (B) MTА АNGELUS, (C) Amalgam. teeth were sectioned in longitudinal manner, marginal gabs measured by the use of a scanning electron microscope. Data was statically analyzed using АNOVА and Tukey Honestly Significant Difference (Tukey's HSD). Results: Bio-C Repair material and MTA show better marginal adaptation with significant difference between them and amalgam, no significant different between Bio-C repair group and MTA group. Conclusion: marginal adaptation better for Bio-C repair in comparison to Amalgam and MTА АNGELUS

Periodontal disease treatment is always a challenging task. Various treatment modalities have been applied for treating this painless chronic condition. With advancement in the field of research in dentistry researchers shifted towards the autologous products hence came the usage of platelet concentrates in various branches of dentistry. Initially fibrin glue, platelet rich plasma (PRP) have been tried but because of their drawbacks platelet rich fibrin (PRF) came into play. Due to possible contamination of silica particles in silica tubes or silica coated plastic tubes and shorter resorption time, titanium attracted the researchers. This lead to introduction of titanium platelet rich fibrin (T-PRF) a second generation platelet concentrate. This had a thicker fibrin meshwork, better cellular entrapment, greater resorption rate and titanium tubes are inert, better haemocompatible and non-corrosive. It also eliminates the possible contamination of silica test tubes and silica coated plastic tubes. Present article is a review on T-PRF and its usage in the field of dentistry.
