Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices and maxillary sinus floor triggered a significant reduction of maxillary sinus mucous membrane thickening. The presence of periodontal bone loss significantly increases maxillary sinus mucous membrane thickening.

Non-infectious complications such as post-extraction pain, trismus, and swelling are extremely common after impacted wisdom tooth removal. The aim of the study was to assess the impact of using kinesio tape on the level of the postoperative swelling of soft tissues, trismus, and pain in patients undergoing the surgical extraction of an impacted mandibular third molar. One hundred patients undergoing the surgical extraction of a lower wisdom tooth were randomly divided into two groups: a study group with kinesio taping (KT) (n = 50) and a control group without kinesio taping (NKT) (n = 50). The surgical procedure was performed according to the same repeatable scheme. Kinesio tape was applied immediately after surgery in the KT group. In both groups, measurements of swelling, trismus, and pain were performed before the surgery and on the third and seventh postprocedural days. Kinesio tape had a significant effect on the decrease in facial swelling on the third day after surgery and a decrease in trismus and pain severity levels on the third and seventh days after surgery. The kinesio tape method is non-invasive, continuously active throughout the entire application period, and requires no additional patient appointments. KT application is an effective method for reducing postoperative edema, pain, and trismus after impacted mandibular wisdom teeth surgery.

Dental injury to the second molar (SM) caused by the surgical extraction of the impacted third molar tends to be underestimated. The necessity of assessment of the impact of the removal of the wisdom tooth in the mandible on the second molar arose. The study group (n = 60) was the one with the second molar on the surgical side, and the control group (n = 60) was the one with the tooth on the opposite side of the alveolar arch. Before the surgery, the difficulty level was assessed according to the Pederson scale. The periodontal status of the SM was assessed by probing depth (PD), gingival index (GI), tooth mobility (TM) examination by the percussion method and resonance frequency. Measurements were taken before and after the surgery, 7 days and 8 weeks after the surgery. The study demonstrated the significant impact of the surgical removal of the wisdom tooth on the PD, GI and TM of the SM. The predicted degree of difficulty of the very difficult surgery had an influence on the increase in PD on the distal buccal and lingual surface of the SM, and on the GI in the proximity of the examined tooth. The results of the presented research confirm the necessity of the clinical assessment of the lower SM before and after the surgical removal of the impacted wisdom tooth in the mandible.

Background: Lactoferrin is an ironbinding glycoprotein with anti-inflammatory and anabolic properties found in many internal fluids. It is worth looking at novel studies, because of their methodology and observations that may once be applicable in modern implantology. The aim of the study is to answer the question if lactoferrin is a promising factor for bone regenerative process in oral surgery. Method: An electronic search was conducted on 14th October 2019 on the PubMed, Scopus and Web of Science databases. The keywords used in the search strategy were: lactoferrin AND bone regeneration AND oral surgery. The qualitative evaluation was conducted using the Jadad and Newcastle-Ottawa Quality Assessment Form. Then a metanalysis of a new bone growth and percentage of the resorbed graft were performed with the metaregression of lactoferrin dose to its outcome effects on bone regeneration. Results: The search strategy identified potential articles: 133 from PubMed, 2 from Scopus, 4 from Web of science. After removal of duplicates, 136 articles were analyzed. Subsequently, 131 papers were excluded because they did not meet the inclusion criteria. The remaining 5 papers were included in the qualitative synthesis. The use of lactoferrin clearly increases the growth of a newly formed bone (2.58, CI:[0.79, 4.37]), as well as shortens the time of the graft resorption (− 1.70, Cl:[3.43, 0.03]) and replaces it with a species-specific bone. Heterogeneity is significant at p < 0.001 level. Metaregression indicates that one unit increase in the log (Treatment dose), i.e. a 2.78 times increase of the Treatment dose, results in an increase of the Effect size by 0.682.

Today, extraction of the impacted third molar is the most common procedure performed in oral surgery departments. One of the methods currently investigated—in terms reducing the severity of non-infectious complications and decreasing Quality of Life following third molar surgeries—is Kinesio Taping (KT). The aim of the study was to evaluate the impact of Kinesio Tape application on Quality of Life. A total of 100 asymptomatic patients with impacted third lower molar were included. The study participants were randomly divided into two groups: a study group with the application of KT (n = 50) and a control group (without KT) (n = 50). Removal of the impacted third lower molar was performed in each patient in a standardized fashion. For assessment of Quality of Life, the modified University of Washington Quality of Life Questionnaire (UW-QoL v4) was used. Patients with Kinesio Tape application scored higher in all domains. Statistically significant differences between the two groups were found in the following domains: “Activity”, “Mood”, “Health-related QoL during the past 7 days” and “Overall QoL during the past 7 days”. There were no significant differences in significant problems and important issues between groups. Kinesio Taping has a significant impact on Quality of Life after impacted third molar removal. It should be considered as one of the noninvasive methods to reduce postoperative non-infectious complications.

BackgroundVarious mandibular indices have been developed to detect osteoporosis on panoramic radiographs. Quantitative ultrasound (QUS) is a low-cost, radiation-free method to assess bone status. The aim of this study was to compare mandibular morphometric analysis and QUS at the radius and proximal phalanx III finger.MethodsThe study involved 97 postmenopausal women, aged 48.5–71.5y (mean: 55.4). Mandibular morphometric analysis comprised: distance between upper and lower mandibular borders just behind the mental foramen (H), distance: mental foramen - inferior mandibular cortex (IM) and mandibular cortical width at the mental region (MCW). Then, ratios were calculated: MCW/IM = PMI (panoramic mandibular index), H/IM = MR (mandibular ratio). Mandibular cortical index (MCI) was used to classify the morphology of the mandibular cortex.Bone mineral status assessed using QUS at the radius and proximal phalanx III finger was compared to population mean apical bone mass (T-score).Linear regression analysis was used for correlations between continuous variables, Pearson’s correlation coefficient r - for variables of normal distribution. Student’s t-test was used to compare variables of normal distribution and for the latter - Mann-Whitney U-test. The level of significance was p < 0.05.ResultsMandibular height was 13.42–34.42 mm. The mean mandibular cortical width was 3.31 mm. Mean values of PMI and MR were 0.33 and 2.57, respectively. Higher mean value of Ad-SoS was found in the radius than in the III finger. Phalanx T-score values ​​were lower than those of the radius. T-score of the radius was < − 1.0 in 22 patients, indicating osteopenia. Basing on phalanx T-score, osteopenia was found in 39 patients. Category C1 of Mandibular Cortical Index was found in 48 women, C2 - in 37 women and C3 - in 12 women. Higher scores of Mandibular Cortical Index were recorded in older women. MCI significantly correlated with the skeletal status (p = 0.01) as well as with H, MCW and MR. Phalanx T-score was not correlated to PMI, MR or MCW.Conclusions1. Mandibular Cortical Index can be used as a screening tool for detecting osteoporosis.2. Quantitative ultrasound at the phalanx III constitutes a reliable way of assessing bone status.Electronic supplementary materialThe online version of this article (10.1186/s12903-018-0593-4) contains supplementary material, which is available to authorized users.

Dental surgeons, maxillofacial surgeons and implantologists are increasingly interested in the effects of vitamin D on bone metabolism and the immune system. The correct concentration of this prohormone potentially correlates with success at each stage of osteointegration of endosseous implants.A review of literature related to the topic of the paper.A suitable level of vitamin D3 is crucial from the day of surgery. It influences the modulation of the immune system -increases the production of cathelicidin and defensin, and reduces the expression of proinflammatory cytokines. It also has a positive effect on bone metabolism in osteo-suppression via the induction of osteoblasts and osteoclasts and continuous bone remodeling around the implant after prosthetic restoration.The prevalence of low vitamin D levels in the European population leads to the conclusion that a high deficit is not a factor directly responsible for failures in the process of osteointegration.

Background: Nicotine absorbed by the skin and also by the digestive, respiratory and excretory systems is one of the most known toxins found in tobacco. This work reviews available literature on the influence of nicotine on human health, and in particular on the oral cavity.Material/Methods: A review of literature related to the topic of the paper. Results:Numerous studies indicate that nicotine adversely affects human health. It exerts a negative effect at the cellular level by modifying metabolism, and disturbs the interactions between tissues, which strongly promotes the formation of cancer-like changes. Nicotine causes numerous pathologies in the respiratory, immune, and cardiovascular systems leading to a number of metabolic disorders. Conclusions:The intake of nicotine contained in tobacco products has a particularly negative effect on the oral cavity.It accelerates periodontitis, with weaker clinical symptoms associated with resistance to conventional treatment. In addition, nicotine changes the oral cavity microflora, increasing the amount of harmful bacteria and pathogenic fungi.
