Background: Dermatofibrosarcoma protuberans of the scalp (DFSP) is a rare soft tissue neoplasm originating from the dermal layer of the skin, usually affecting the adults.

Case report: The current case report presents a 48-year old male with a huge lump on the right side of parietal region. A wide local excision of the tumor was performed and the excised specimen was sent for histopathological examination. Histopathology and Immunohistochemistry was suggestive of DFSP.

Conclusion: Dermatofibrosarcoma protuberans is a rare neoplasm affecting the head and neck region. This unusual entity is more likely to recur when a small margin of surgical excision is performed. Wide local excision is the gold standard treatment and radiotherapy is preferred in recurrent diseases.

The aim of the study: Compare the properties of different dental implants depending on the design, shape and surface area in the experiment.

Materials and methods: Dental implants with similar sizes (5.5×10 mm) were selected: Vitaplant VPKS, Mega Gen AnyRidge and Alpha Dent Superior Active. The calculation of the total area of the implants was performed and the implants were immersed in a ferromagnetic substance.

Results and discussion: The small number of turns and their small length of the Vitaplant implant cannot create a large surface area (this size of the implant has an area of 174.7 mm²). On the thin, slightly conical body of the MegaGen implant (North Korea), the developer placed 10 turns of thread with wide blades. Due to the data design features, this implant has the largest surface area (276.5 mm²), which is an advantage in implant integration. The same number of turns (10) and a very similar frequency bring Alpha Dent implants (Germany) closer to the implant described above, but the design implements an innovative anti-rotation system. This implant size has a total surface area of 210.5 mm².

Conclusions: The implant Vitaplant VPKS is inferior in efficiency of the geometry of the implant Mega Gen AnyRidge by 24%, and the implant Alpha Dent Superior Active in turn ahead of the efficiency of the representative of the Korean company by 8.9%. The shape of the geometry of the implant affects the effectiveness of counteracting the masticatory load more than its surface area.

Background and objective: According to Klassen et al. (2012), the overall quality of life of CL/P children is most affected by appearance and quality of speech, as these differences are most noticeable to others. To what extent changes in craniofacial growth have an impact on speech quality has yet to be clarified. Therefore, we aimed to determine which cephalometric parameters differed between healthy and cleft palate groups.

Material and methods: 17 healthy and 11 children born with CL/P were included. We conducted a cross-sectional and comparative study. A combination of objective and subjective assessment methods was performed: nasalance scores were calculated, and lateral cephalograms were evaluated by indirect digitization using Dolphin Imaging Software.

Results: The analysis showed differences in the length of the hard (PNS-A) and soft palate (PNS-P), and in the width of the lower oropharyngeal airway (AW5-AW6). The mean length of the hard palate was 3.7 mm and the soft palate 3.0 mm shorter in the CL/P group compared to the healthy group. Hypernasal resonance was related to (1) the length of the hard palate, (2) the distance between the hyoid bone from the third cervical vertebra, and (3) the angle formed by the NA line and the NB line (ANB). Only 11 CL/P children met the inclusion criteria. Thus, the results may have been affected by the small sample size. The Control group consisted of children who visited ENT doctors or orthodontists.

Conclusion: The results showed differences in cephalometric parameters in the two groups. Still, we continue to collect data and plan to conduct the analysis on larger and more homogenous sample size.

Aim: To analyze the latest systemic and topical recurrent aphthous stomatitis (RAS) treatment methods that could help patients in their daily lives.

Material and methods: A systematic literature review was performed of randomized control trials in English identified in MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (Cochrane Library), Researchgate, published between 2018 and 2023. Studies had to be performed in vivo.

Results: 34 randomized clinical trials matched all criterias and were included in systematic literature review. A wide variety of topical and systemic agents are suggested for the treatment of RAS.

Conclusion: Topical medications can promote the healing time of ulcers and relieve the pain, but most of the time can not decrease the frequency of RAS relapse. However, for continuous RAS, treatment with systemic medication should be considered.

Aim: This study investigated whether the self-implemented preventive measures practiced among the 6 and 12 years olds in Riga, Latvia can control the caries increment due to poor dietary habits among this age groups.

Material and methods: Caries examination was performed on Thirty-eight 6 and thirty-nine 12 years olds by visual and bitewing radiographic examination at baseline and after 3 years. All participants and/or their parents completed dietary habits questionnaires. The data was analyzed using t-test, chi-square test, ANOVA and frequency tables, Wilcoxon and Fisher's tests (α=0.05).

Results: The mean (SD) values of caries experience at baseline/3-year period in 6- vs.12-year olds were as follows. DMFS: 0.72 (1.02)/3.13 (3.13) (p=0.0000) vs. 6.79 (5.14)/14.79 (9.86) (p=0.0000); dmfs: 11.26(8.71)/7.74 (4.86) (p=0.078) vs. 3.57 (2.03)/1.5 (0.71) (p=0.317). The statistical significance was reported only for the consumption of soft drinks (p=0.032) and sugared tea (p=0.018) for the 6 years olds, and for sugared tea (p=0.017) and number of teaspoons of sugar added to tea (p=0.0095) for the 12-years olds. There was positive caries increment in all the 6 and 12 years olds that reported significant increase in consumption of soft drinks and sugared tea, and increase daily number of teaspoons of sugar used in tea.

Conclusions: The present study demonstrated high cariogenic diet among the children in Riga, which is associated with increased caries experience that the currently practiced self-implemented oral hygiene measures was not capable of controlling.

Objective: To clarify antibiotic use by oral and maxillofacial surgeons in mandibular fracture patients and evaluate practices based on scientific evidence.

Material and methods: We assessed antibiotic use in simple symphysis and angle mandibular fractures among oral and maxillofacial surgeons in the Nordic countries through an e-survey. In addition, we performed a literature review of antibiotic administration in mandibular fracture surgery.

Results: A total of 41 oral and maxillofacial surgeons who treat mandibular fractures responded to the questionnaire. Timing and duration of antibiotic use varied. The duration of postoperative antibiotic treatment ranged from 1 to 7 days (mean 5.6 days). Respondents' practices were not in concordance with scientific evidence. According to previous studies, restricting antibiotic exposure to a maximum of 24 hours postoperatively was not related to a higher risk of surgical site infections. No articles described a benefit of prolonged postoperative antibiotic therapy.

Conclusions: Antibiotic use in connection with mandibular fracture treatment varied in the Nordic countries and antibiotic practices are not in concordance with the current literature. Restricting antibiotic exposure to a maximum of 24 hours postoperatively should be considered. Clear guidelines for antibiotic prophylaxis as part of the surgical management of mandibular fractures are required.

Aim: The aim of this systematic literature review is to analyze the literature about the prevalence of peri-implantitis and peri-implant mucositis in patients with periodontal diseases and compare their prevalence in pristine and augmented sites.

Material and methods: A systematic literature review was performed of clinical trials, controlled clinical trials, comparative studies, and clinical studies. In the studies, patients who have periodontal diseases and need a dental implant with or without bone grafts were selected. Records about peri-implantitis and peri-implant mucositis, implant survival and success rates were extracted.

Results: 19 studies with 3049 patients were selected. X had a periodontal disease. After analysis, peri-implant mucositis was more prevalent in augmented sites (19% - 74.0% on patient level, 10.2% - 62,5% on implant level). Prevalence of peri-implantitis was not apparent because of missing data and heterogeneity of records. Implant survival and success rates were lower in augmented sites.

Conclusion: When alveolar ridge augmentation is needed for dental implant in patients with periodontal diseases, dentists must evaluate the risk of long term biological complications.

Background: Type II diabetes mellitus (T2DM) is a chronic endocrine disease affecting over 6% of the world population. Sustained hyperglycaemia plays a role in inhibited healing and chronic inflammation which can lead to complications after root canal treatment, such as delayed healing of apical periodontitis.

Material and methods: The systematic review adhered to PRISMA guidelines and databases of PubMed, ScienceDirect, and The Cochrane library were used to perform the search. The search was carried out between November 15 and November 30 in the year 2021.

Aim: To evaluate the relationship between apical periodontitis and root canal treatment in patients with type II diabetes.

Results: Primary database search yielded 313 results. After checking the content and relevance of the articles, 4 articles were used with a total of 15810 patients. Out of 4 studies, 3 concluded that apical periodontitis after root canal treatment was statistically significantly more frequent in patients with T2DM than in control groups. However, the results from another study showed that there is no significant correlation between T2DM and post-treatment apical periodontitis (p>0.05).

Conclusions: A statistically significant relationship was found between T2DM patients and the occurrence of apical periodontitis in most studies.

Objective: Relevance of the problem and the aim: A variety of surgical treatment modalities are analyzed to treat medication-related osteonecrosis of the jaw, using different adjuvant therapies (fluorescence-guided surgery, autologous platelet concentrates) and thus to improve bone and mucosa healing in the postoperative period and reduce the risk of recurrence of osteonecrosis. The purpose of the present systematic review is to compare the effectiveness of different surgical treatments for medication-related osteonecrosis of the jaw (with applications of autologous platelet concentrates, fluorescence guidance, or without adjuvant measures).

Materials and methods: The protocol for the systematic review was prepared according to the PRISMA and Cochrane guidelines for systematic reviews. Electronic databases used: PubMed, The Cochrane Library, Science Direct, Wiley Online Library. The review includes articles investigating surgical treatment methods for medication-related osteonecrosis of the jaw.

Results: Twelve scientific articles were included in the review. The studies evaluated the efficacy of autologous platelet concentrates, fluorescence-guided surgery, or standard surgical treatment techniques without adjuvant therapies. The efficiency of curettage, sequestrectomy, and the use of autologous platelet concentrates have been found to range from 80% to 96.7%. The efficiency of fluorescence-guided surgery varied from 83.3% to 94.4%. The highest efficiency range of treatment results was determined by evaluating the surgical treatment without adjuvant therapies, which can reach from 22.22% to 93.2%.

Conclusions: The best and most stable results in the surgical treatment of medication-related osteonecrosis of the jaw are achieved by the application of autologous platelet concentrates after surgical removal of necrotic bone or fluorescence-guided surgery.

Background: Reconstruction of the helical upper-third is often technically demanding, especially when the defect is huge and the ear is severely deformed. The aim of this short communication was to present an alternative technique to rebuild this difficult task, using a modification of the Bardach's three-legged rotation flap for scalp closure.

Methods: To achieve the flap design, we raised the retro- and supraauricular tissue with the Dieffenbach's postauricular advancement fl ap. The Gillies' V-Y advancement fl ap helped to develop the preauricular fl ap, and the Mustardé's otoplastik technique was used to reduce the gap between the resected ear cartilage and the temple.

Conclusion: This flap technique appears simple and quick; thereby, it can be used as a single-staged reconstruction alternative in aging patients with multiple comorbidities.
