Objective: Evaluate the influence of different wound closure methods in terms of pain, swelling, trismus, infection and healing time after third molar extraction.

Material and methods: A literature analysis was performed according to PRISMA guidelines in search of clinical trials published between 2015 and 2020. Databases were searched using different combinations of the following keywords: mandibular impacted OR retained wisdom teeth OR third molar removal OR extraction AND surgical removal AND discomfort OR pain OR trismus OR swelling AND drain OR drainage. The literature search resulted in a total of 364 publications. Finally, 12 study articles were used in the present review, following a selection based on the preestablished eligibility criteria.

Results: The significant difference between various wound closure ways and postoperative pain, swelling and trismus has been found in 8 of 12 analyzed articles. Three of five established beneficial effect of drain application. In other articles, examining different wound closure methodologies, significant benefits were found by using buccally based triangular, buccal mucosal-advancement, and modified envelope flap. Suture-less anterior releasing incision and secondary wound closure also could be favorable after removing impacted third molars.

Conclusion: There was no significant effect of a rubber drain on swelling, pain, trismus, or wound infections after removal of the asymptomatic impacted third molar(s). Secondary wound closure was found to ensure lower pain, swelling and trismus ratio with comparison to primary wound closure.

Objective: The aim of this article is to review the effect of enamel matrix derivate (EMD) on growth factors activation for periodontal regeneration.

Material and methods: Online databases, such as PubMed, Cochrane Library, PMC, Science Direct were searched by using the following keywords in various combinations: emdogain, periodontal regeneration, growth factors, transforming growth factor, bone morphogenetic protein, fibroblast growth factor and vascular endothelial growth factors. All studies fulfilling the selection criteria were carefully reviewed for the focused question: "Does enamel matrix derivate induces the activity of growth factors, important in periodontal regeneration?".

Results: 1378 articles were found in the databases using keywords. After duplicate citations screened, inclusion/exclusion criteria applied, excluded articles after titles, summaries and full-text reading 14 articles were included in the literature review.

Conclusion: Enamel matrix derivate (EMD) was found to have a possitive effect on periodontal tissue regneration. By stimulating secretion and activating functions of growth factors, such as transforming growth factor-β (TGF-β), bone morphogenetic proteins (BMP), vascular endothelial growth factors (VEGF) and fibroblast growth factor-2 (FGF-2), EMD induces production of new alveolar bone, new root cementum and functionl periodontal ligament (PDL) and new blood vessels formation in periodontal area. Due to this production, the probing depth of periodontal pocket is being reduced.

The aim of this paper was to analyze the literature published in the research related to sodium hypochlorite induced injury. An internet search using search engines (Google, Researchgate and PubMed) was carried out. The keywords used for search were sodium hypochlorite, injury, cellulitis, apical extrusion, ulcer, endodontics. Full text articles of the articles were collected from the year 2007 to 2017. The data available from the clinical trials the journal articles were analyzed and presented in both tabular and descriptive patterns.

Objective: Non-syndromic (N/S) cleft lip and/or palate is the most common congenital anomaly to undergo long multidisciplinary treatment. This study investigates patients living with orofacial anomaly and having prolonged treatment by evaluating OHRQoL. It is essential to understand its influence on affected patients' daily life to prepare the most appropriate care for the complete physical, mental, and social well-being of an individual.

Materials and methods: In order to evaluate the influence of undergoing treatment and living with an orofacial anomaly on patients' OHRQoL, randomly selected patients with N/S cleft lip and (or) palate treated in the Clinic of Orthodontics of Lithuanian University of Health Sciences filled a modified CPQ questionnaire. The questionnaire of 60 closed questions was about undergoing treatment and its effect on patients' self-confidence level, mastication, fluent pronunciation, discomfort, ability to socialize, emotions, etc. Statistical data was expressed as a frequency and percentage.

Results: Of the 20 patients 13-24 year-old (mean age 16.2±3.25) 50% were males, 50% were females, 80% wore orthodontic braces, other 20% wore Quadhelix appliance. All 20 patients experienced pain during treatment, 60% of all patients avoided being among people, were bullied. 65% of respondents felt more confident and happy after orthodontic treatment began. 70% of all patients experienced difficulty in speaking, biting hard food.

Conclusion: The questionnaire showed no difference between different orthodontic appliance types and patients' OHRQoL, although overall prolonged treatment and orofacial anomaly does affect a patient's regular daily functions, oral hygiene habits, self-confidence level, social life, and mental well-being.

Objective: The study aimed to obtain nasalance scores for Vietnamese-speaking patients with repaired cleft palate with or without cleft lip.

Methods: A total of 29 children with cleft palate with or without cleft lip (4-18 years old, mean age 7.9±3.5 years old) were included in this study. Speech material was designed specifically for the Vietnamese language. The speech material consisted of oral stimuli (19 oral words and 18 oral sentences), oro-nasal stimuli (eight sentences), and nasal stimuli (seven sentences). The patients repeated the stimuli after the examiner. The Nasometer II (model 6450) was used to compute nasalance scores.

Results: The mean nasalance scores were 27.1% for oral stimuli, 40.2% for oro-nasal stimuli, and 57.5% for nasal stimuli. Hypernasality was detected in 41.4% of the patients.

Conclusion: Vietnamese-speaking patients with repaired cleft palate with or without cleft lip who did not undergo speech therapy had poor speech outcomes.

Background: Medication related osteonecrosis of the jaw (MRONJ) is a severe adverse drug reaction occurring as a progressive bone destruction in the maxillofacial region. MRONJ is usually initiated after oral surgery procedures, however periodontal disease and other chronic inflammations are also risk factors. There is no clear treatment protocol for management of MRONJ, for this reason autologous platelet concentrates (APC) have been introduced to enhance the healing process.

Aim: To evaluate the effectiveness of APCs in treatment of MRONJ.

Methods: A systematic literature review was performed according to PRISMA guidelines in MEDLINE (PubMed) and Google Scholar databases. Only no older than 5 years, in vivo studies in English with follow-up until condition totally resolves were included.

Results: A total of 2683 publications were identified out of which only 7 met the inclusion criteria, 6 cohort and 1 randomized clinical trial. Most of the studies preferred platelet rich fibrin (PRF) and only one used platelet rich plasma (PRP) in MRONJ treatment. MRONJ stage, patients mean age, drug therapy, follow-up and success rate were analysed in all the studies. Five studies also named how MRONJ initiated and 4 studies mentioned duration of drug intake before developing MRONJ.

Conclusion: The published data is not sufficient to confirm a specific treatment protocol although the published results are promising. More prospective randomized controlled clinical trials are required in order to evaluate the effectiveness of APCs for treatment of MRONJ.

A novel coronavirus (2019-nCoV) is associated with human-to-human transmission. From its beginning in December 2019, the coronavirus disease 2019 (COVID-19) outbreak has spread globally from Wuhan and is now declared a pandemic by the World Health Organization (WHO). The person-to-person transmission routes of 2019-nCoV includes direct transmission, such as cough, sneeze, droplet inhalation transmission, and contact transmission, such as the contact with oral, nasal and eye mucous membranes. The participants in dental practice are exposed to a severe risk of 2019-nCoV infections because of the face-to-face communication and the exposure to saliva, blood, and other body fluids. Dental professionals play great roles in preventing the transmission of 2019-nCoV. Since ozone has a proven anti-viral action, we present a project on the use of ozonized water in the water circuit of the dental armchair, in order to lower the viral load during dental practice in dental clinics and hospitals.

Early diagnosis of neurofibromatosis is significant to start the multidisciplinary approach of this type of patient. This syndrome may be first identified in pediatric dental care. This study is about a 9-year-old patient who was diagnosed with neurofibromatosis type 1 from a plexiform neurofibroma displayed in the left hemi-maxilla. From the microscopic diagnosis of the lesion the investigation of other related injuries began, according to the diagnostic criteria of the National Institute of Health (NIH), leading to the diagnosis of systemic alterations. The parental awareness about the condition and the establishment of multidisciplinary care are important for the treatment to be more conservative and the patient has fewer complications with better quality of life. The use of the diagnostic criteria in this case shows how methodization is important for reaching more accurate and reliable diagnoses.

Objectives: To evaluate oral health conditions and determine risk factors of dental caries of adolescents living in social care homes in the South of Lithuania and to compare the results with adolescents of the same age in general population.

Materials and methods: Subjects of study are 12 and 15 year-old adolescents from all social care homes and 3 schools of Alytus county, Marijampole county and Vilnius city. 55 adolescents living in social care homes (study group) and 55 adolescents living outside social risk families (control group) were clinically examined between February and September of 2019. The clinical study assessed: 1) the prevalence and incidence of caries using the decayed-missing-filled teeth (DMFT) index, 2) the oral hygiene status using the Silness and Loe index, 3) the salivary buffer capacity using Ivoclar Vivadent CRT Buffer indicators. The R-package was used for statistical analyses. Threshold for statistical significance set at p<0.05.

Results: Prevalence and incidence of caries in study group was higher compared with adolescents of the same age in general population - prevalence 81.82 % and 69.1 %, respectively, DMFT medians 3 and 1, respectively. Social living environment, age or gender were not statistically significant determinants for oral hygiene or salivary buffer capacity. The correlation between oral hygiene and DMFT indices was statistically significant. Both - oral hygiene and salivary buffer capacity - fit into linear regression model and were statistically significant.

Conclusions: Adolescents, living in social care homes, were found to have poorer oral health with higher prevalence of caries than those living in families. Poor oral hygiene and low salivary buffer capacity have been identified as significant risk factors for the development of caries.

Objectives: Restorative materials may be exposed in the oral cavity to chemical agents found in beverages, which may lead to their biodegradation. The purpose of this in vitro study was to evaluate the effect of two fruit drinks commonly used by children on surface roughness of two esthetic restorative materials.

Materials and methods: One resin composite (RC), one resin-modified glass ionomer (RMGI) and two fruit drinks (orange and cocktail) were used in this study. Specimens (n=20) of each material were fabricated against Mylar strip. Baseline measurements of surface roughness were recorded for each group using noncontact surface profilometer. Each specimen was placed in the tested fruit drinks for 24 hours and then surface roughness was recorded.

Results: The mean (±SD) surface roughness of RC before and after immersion in orange and cocktail were 0.04±0.02, 0.12±0.05, 0.06±0.03 and 0.11±0.06, respectively and for RMGI were 0.72±0.14, 0.60±0.19, 0.56±0.11, and 0.52±0.15. For RC there was significant difference between surface roughness (Sa) before and after immersion in orange and cocktail (P<0.05). For RMGI, there was significant difference between surface roughness before and after immersion in orange (P<0.05), but no significant difference before and after immersion in cocktail (P>0.05).

Conclusions: The surface roughness of the RC and RMGI examined showed a significant change in the surface roughness after immersion for 24 hours in the tested fruit drinks.
