Maintenance of proper oral hygiene by dental plaque elimination is one of the most important factors affecting the healing process in postoperative oral wounds. Propolis is a substance produced by bees. Ethanolic extract of propolis has bactericidal, fungicidal, anti-inflammatory, and antioxidative properties. Moreover, it can scavenge free radicals. The purpose of this paper is to demonstrate the efficacy of a gel containing 3% of ethanolic extract of Brazilian green propolis (EEP-B) when used for maintaining oral hygiene in patients with postoperative oral mucosal wounds. The hygiene was assessed using API, OHI, and SBI followed by microbiological examinations. The patients were divided into two groups. Group 1 consisted of those who used a gel containing EEP-B for oral hygiene, and group 2 consisted of those who used a gel without EEP-B. Although improved oral hygiene was noted in both groups, the improvement was markedly greater in the group using gel containing EEP-B. Summing up the results of microbiological examinations, EEP-B has beneficial effect on mouth microflora in postoperative period. Propolis preparations used for oral hygiene allow eliminating microorganisms of pathogenic character and physiological flora microorganisms considered as being opportunistic, with no harmful influence on physiological microflora in oral ecosystem.

The aim of this study was to evaluate the effect of toothpaste containing natural tea tree essential oil (TTO) and ethanolic extract of propolis (EEP), on microflora and selected indicators of oral health in patients using removable acrylic partial dentures. Fifty patients with varying conditions of hygiene were divided into two groups. The study group received the toothpaste with TTO and EEP, while the control group received the same toothpaste but without TTO and EEP. At the first visit, oral hygiene and hygiene of the prostheses were carried out. Control visits took place 7 and 28 days later and compared to baseline. Indexes like API (Approximal Plaque Index), mSBI (modified Sulcus Bleeding Index), OHI-s (simplified Oral Hygiene Index), and DPI (Denture Plaque Index) were assessed in three subsequent stages, and swabs were collected from floor of the mouth area to assess the microbiota. After 7 and 28 days of using the toothpaste with TTO and EEP, a statistically significant decrease of the examined indicator values were observed in the study group as compared to the values upon the initial visit. The number of isolated strains of microorganisms in the study group was decreased or maintained at the same level, whereas in the control group an increase in the number of isolated strains was observed. The observed stabilization of oral microbiota in patients from the study group confirms the beneficial activity of toothpaste containing EEP and TTO compared to the control group.

Relevance. Odontogenic infection is one of the most important problems of dental science. The variety of anti-inflammatory oral hygiene products determines the need for targeted selection of preventive toothpastes and rinses, balms, foams, elixirs, as well as monitoring and training the algorithm of hygienic measures for a patient with an odontogenic infection. The aim of the study was to study the hygienic status of the adult population for the selection of individual oral hygiene products for odontogenic infection, taking into account social and hygienic factors.Materials and methods. The study examined the prevalence of odontogenic infection in the adult population to determine the need for professional care and dental education. The study involved 198 people without somatic pathology, who were allocated into four groups according to the performed oral care and taking into account the dental status and the intensity of oral microbiota formation in the adult population. The patients were followed-up every week for one month. The study examined the simplified oral hygiene index by GreenVermillion (OHI-S), PMA index and Mühlemann and Son sulcus bleeding index, which allowed calculating the effectiveness of oral care products.Results. The preventive care effectiveness evaluation showed an increase in the cleansing effect in the adult population over the entire study period. The anti-inflammatory effectiveness analysis demonstrated positive changes: by the end of the study, the PMA index was 51.52 ± 3.40% in group 1; it increased by a factor of 3 and amounted to 44.17 ± 2.77% in group 2; 56.51 ± 4.61% – in group 3, 48.95 ± 3.60% – in group 4. The Mühlemann and Son sulcus bleeding index demonstrated the changes in the periodontal tissue condition and amounted to 52.78 ± 3.62% in group 1, 44.11 ± 3.54% in group 2, 54.97 ± 3.98% in group 3, 47.78 ± 2.73% in group 4.Conclusions. The development of oral health promotion measures determines the significance of oral care products for the prevention of odontogenic infection in the adult population, which plays a crucial role in the individual program planning for the main dental disease prevention.

Background: Conflicting results have been reported concerning the progression of medial meniscal extrusion (MME) after arthroscopic transtibial pull-out repair of medial meniscus posterior root tear (MMRT), and no study has evaluated the relevant factors affecting the progression of MME. Purpose: To (1) evaluate the subjective and objective surgical outcomes of arthroscopic transtibial pull-out repair of MMRT and (2) identify relevant factors affecting the progression of MME after surgery. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 63 patients who underwent isolated arthroscopic transtibial pull-out repair of MMRT between January 2010 and June 2017 were evaluated retrospectively. Clinical scores and various radiographic parameters were evaluated to assess the surgical outcomes. The patients were classified into 2 groups according to the change in medial meniscal extrusion ratio (MMER) at 1 year after surgery compared with before surgery (group 1 consisted of 21 patients with reduced or maintained MMER; group 2 consisted of 42 patients with increased MMER). Variables including baseline demographics, radiographic parameters, and arthroscopic findings were compared to identify relevant factors affecting the progression of MME after surgery. Results: In the overall cohort, clinical outcomes at postoperative 2 years improved significantly ( P < .001 for visual analog scale score, International Knee Documentation Committee subjective score, and Lysholm score), whereas radiographic parameters showed an overall deterioration compared with the preoperative level. In subgroup comparisons, a significant difference was seen in the time from the onset of symptoms until surgery ( P < .001), defined as preoperative symptom duration, which a subsequent logistic regression analysis revealed to be a relevant factor associated with the progression of MMER ( P = .015). Both groups showed progression of radiographic osteoarthritis, but the progression was significantly higher in group 2 compared with group 1 at postoperative 2 years ( P = .032). On receiver operating characteristic curve analysis, the cutoff point for preoperative symptom duration associated with the progression of MMER was 13 weeks (sensitivity, 52.4%; specificity, 76.2%; accuracy, 72.4%). Conclusion: The arthroscopic transtibial pull-out repair of MMRT showed clinical improvement but did not prevent the progression of knee osteoarthritis, MME, or MMER. Although the preservation of MMER was not capable of completely preventing the progression of knee degeneration, MMER still has a potential clinical value in delaying the rate of progression of knee degeneration. Early surgical repair of MMRT, within 13 weeks from the onset of symptoms, might be helpful to prevent the progression of MME.

ABSTRACT Since the alveolar process is tissue “dental dependent,” after the extraction of the dental element, this process suffers some degree of atrophy during the healing process, which can be reduced with the installation of immediate implants, aiming to maintain the original bone architecture. The aim of this study was to investigate the influence of the time of implant placement on bone formation around them. Seven dogs were selected and randomly divided into two groups: Group 1, where implants were placed immediately after extraction of two lower premolars without flap elevation, and group 2, where implants were delayed by 4 months after extractions. Each group received 14 implants, and 4 months after the second surgery, the samples were processed and analyzed histomorphometrically. A mean average analysis and the Kruskal–Wallis test (p < 0.05) were performed. The buccal bone–implant contact (BIC) mean average was found larger in immediate implants (42.61%) compared with delayed implants (37.69%). Group 1 had statistically higher outcomes in bone formation and BIC on the buccal bone wall. It was concluded that performing immediate implants with the palatal approach technique and leaving a buccal GAP enables a higher or at least equal rate to BIC and bone area around them, when compared with delayed implants. Actually, the patients and dentists want to do a shorter treatment with satisfactory results, but it is necessary to understand whether different times of implant placement can influence the results and longevity of the treatment.

Abstract Background: Parallel osteotomy is essential for favorable osteotomy reduction and healing and technically challenging during diaphyseal ulnar shortening osteotomy (USO). This study aimed to evaluate the advantages of guided osteotomy for parallel osteotomy and reduction osteotomies and healing over freehand osteotomy. It also aimed to identify surgical factors affecting healing after diaphyseal USO.Methods: Between June 2005 and March 2016, 136 wrists that had undergone diaphyseal USO for ulnar impaction syndrome (UIS) were evaluated. The wrists were divided into two groups according to the osteotomy technique (Group 1: freehand osteotomy, 74 wrists; Group 2: guided osteotomy, 62 wrists). The osteotomy reduction gap and time to osteotomy healing (union and consolidation) were compared between the groups. A multiple regression test was performed to identify the surgical factors affecting healing. The cut-off length of the reduction gap to achieve osteotomy union on time and the cut-off period to decide the failure of complete consolidation were statistically calculated. Results: The baseline characteristics were not different between the two groups. The osteotomy reduction gap, time to osteotomy union, and complete consolidation were shorter in Group 2 than in Group 1 (p=0.002, <0.001, 0.002). The osteotomy reduction gap was a critical surgical factor affecting both time to osteotomy union and complete consolidation (p<0.001, <0.001). The use of a dynamic compression plate affected only the time to complete consolidation (p<0.001). The cut-off length of the osteotomy reduction gap to achieve osteotomy union on time was 0.85 mm. The cut-off period to decide the failure of complete consolidation was 23.5 months after osteotomy.Conclusions The minimal osteotomy reduction gap was the most important for timely osteotomy healing in the healthy ulna and a guided osteotomy was beneficial to reducing the osteotomy reduction gap during USO.

Orthodontic treatment may affect the equilibrium of oral microbiota which plays a major role in aetiology of periodontal disease. This prospective clinical study aimed to assess the periodontal health and microbiological profile of healthy (Group 1) and stabilised periodontal (Group 2) patients throughout three months of orthodontic treatment. Upper and lower fixed orthodontic appliances were bonded. Periodontal health was assessed using plaque score (PS), bleeding on probing (BOP) and pocket depth (PD). 29 sites were taken for subgingival plaque sampling. Plaque samples were inoculated on Trypticase Soy Blood Agar (TSBA) and Trypticase Soy Bacitracin Vancomycin (TSBV) agar for assessment of aerobe, anaerobe, black pigmented bacteria (BPB) and Aggregatibacter actinomycetemcomitans. All the measurements were taken before bonding (T0), 1 week (T1), 1 month (T2) and 3 months post-bonding (T3). Generally, periodontal health in both groups were almost similar. After 1 week, the number of aerobes was significantly higher in Group 1 (88%) while the anaerobes were significantly higher in Group 2 (45%). A. actinomycetemcomitans was higher in Group 1 at T0 and T1 but was significantly higher in Group 2 at T3. BPB was minimal at all time with no significant difference. Thus, during the first 3-month of orthodontic treatment, there were significant changes in the number of aerobes-anaerobes in both healthy and stabilised periodontal patients. Pathogenic bacteria would increase during early treatment of orthodontics.

SummaryA 10 mm-long (Group #1) or 20 mmlong (Group #2) segmental osteoperiosteal defect was performed on the metatarsus of ten adult ewes (5+5). The goal of the study was to search for a critical size defect model leading to nonunion. The bone gap was maintained for three months with an internal fixation device involving two plates set in orthogonal planes. Radiological and histological examinations were performed on harvested metatarsal bones. Three months after surgery Group #1 animals showed obvious signs of bone healing without achieving complete union in all cases. Evidence of a healing process was not observed in Group #2 animals, and histological examination confirmed the complete failure of bone repair in the 20 mm gaps. These results are comparable to those of other authors who have concluded that a bone gap corresponding to 1.4 times the diaphyseal diameter overshoots physiological bone healing capacities. This long bone defect model showed good biological properties allowing callus settlement with minimal impairment in Group #1 and permitted weightbearing and unrestricted motion in the animals. Such a sheep model would be useful for testing hard tissue biomaterials, bone healing enhancement or further developed as an experimental nonunion model.Metatarsal diaphyseal defects (length: 10 or 20 mm) maintained with plates were performed in sheep in search of nonunion after a three-month period. Radiological and histological examinations showed that 10 mm gaps healed spontaneously while 20 mm gaps did not. These results are comparable to those of other authors who concluded that a diaphyseal defect whose length exceeds 1.4 times its diameter is unable to repair. The good biological properties exhibited by this defect model seem to be convenient for testing bone substitutes or bone healing enhancement techniques.

Introduction. Oral health is considered as one of the essential components of the overall health of every individual. Maintaining oral health is a gradual process that requires commitment. Children who require special care such as hearing impairment experience difficulty in maintaining oral health primarily due to communication difficulties. This study is aimed at using different interventions to evaluate the improvement of oral hygiene in hearing impaired children. Materials and Methods. Fifty-nine children were recruited in this study that were allocated randomly into each group with twenty children as follows: group 1: pictorial, group 2: video, and group 3: control. Mean plaque and gingival scores were noted before and after the use of different interventions. Oral hygiene was categorized as “excellent,” “good,” and “fair.” Gingival health was categorized as “healthy,” “mild gingivitis,” and “moderate gingivitis.” Results. Thirty-four children (57.6%) were from 12-13 years of age bracket, and 25 (42.4%) belonged to 14-16 years of age. Regarding gender, there were 37 (62.7%) males and 22 (37.3%) females. About comparison of mean gingival and plaque scores before and after interventions in each group, a significant difference was found in group 1 ( p < 0.001 ) and group 2 ( p < 0.001 ), as compared to group 3 where the difference in scores was not significant ( p > 0.05 ). Conclusion. Maintaining oral health requires the compliance of individuals to perform different methods of preventive dentistry, such as tooth brushing and use of dental floss. The use of different oral hygiene educational interventions such as pictorial and video methods have been proven and useful for hearing impaired children in improving oral health.
