The aim of this systematic review is to compare home and office desensitizers containing bioactive glass with control groups in randomized controlled trials (RCT) conducted between 2018 and 2022. ...According to PRISMA guidelines, three electronic databases (Scopus, PubMed, and Cochrane Library) were searched for published scientific articles in October 2022. RCT with adult participants with dentin hypersensitivity (DH) diagnosed by evaporative, mechanical, or thermal stimulation, with a follow-up period and quantified pain assessment were included in the study. Studies that reported DH due to tooth restoration, crown preparation, bleaching, or periodontal surgery or used bioactive glass-ceramics were excluded. The quality of the studies was assessed using version 2 of the Cochrane Risk-of-Bias Tool for randomized studies (RoB 2 tool). Articles that were duplicative or unrelated to this study were excluded. Nine articles were selected for full-text evaluation, whereas two articles were rejected. The remaining seven reports were included in this review. The calcium sodium phosphosilicate group (CSPS) was not significantly different from the positive control groups. Compared with the control groups, fluoro calcium phosphosilicate (FCPS) may be the most effective long-term treatment option. In terms of DH symptom reduction, the FCPS group performed better than the CSPS group. CSPS at a concentration of 5-15% and FCPS at a concentration of 5% are effective in treating DH in adult participants.
Sports activities may induce long-lasting changes in mandibular trajectories. The aim was to compare condylar and mandibular movements in athletes with orofacial injuries with values measured in ...non-injured athletes. The group of 132 athletes without mandibular injury included asymptomatic athletes with a history of a blow to the right side (N = 43) and the group included asymptomatic athletes with a history of a blow to the left side (N = 41) of the mandible. The injured athletes suffered from stiffness/pain and/or limitation of jaw movements. The symptoms disappeared shortly after the injury. Athletes with a history of injury have smaller mean values of Bennett angle on the side of impact, and Bennett angle on the opposite side is greater than the mean found in non-injured athletes. Significantly smaller Bennett angle values in athletes with a history of a blow to one side of the mandible are due to the adaptability of the orofacial system. The larger Bennett angle on the opposite side of the injury is also due to the adaptive mechanism of the TMJ. Clinical Relevance: An individualized approach to TMJ values is mandatory in restorative procedures in every patient, especially in patients with a history of trauma to the orofacial system.
Introduction: A slide in centric is defined as a slide from centric relation to maximum intercuspation. Understanding contact between natural teeth is important for longevity of the stomatognathic ...system, diagnosis and therapy planning. The aim of this study was to determine the difference in the length of slide in centric in population according to dental status, sex and previous orthodontic therapy.
Materials and methods: The study was conducted on a sample of 33 students at the University of Split, School of Medicine (dental study).
Results: Slide values do not follow normal or Gaussian distribution according to the Kolmogorov–Smirnov test (p<0.05). For that reason, they were represented by the median as a measure of central tendency. The arithmetic mean of a slide in centric is 0.95 mm ± 0.47 mm. A slide in centric was not present in only 10% of the subjects. A slide between 0.5 mm and 1.5 mm to maximum intercuspation was present in 90% of the examinees. There was no statistically significant difference in the length of slide between the subjects who had all teeth and those who had missing teeth 1-4 (z= 0.507; p= 0.612). There was no significant difference in the length of slide between women and men (z= 0, p=1). There was no significant difference in the length of slide between the patients who underwent orthodontic therapy and those who did not (z=0.253; p=0.800).
Conclusion: There is some controversy about slide in centric and its etiological role in the development of temporomandibular disorders. Slide in centric is very significant because it indicates occlusal instability and can eventually lead to temporomandibular dysfunction, which do not have to be of the same aetiology.
To prospectively assess self-perceived chewing function (CF) and oral health-related quality of life (OHRQoL) in geriatric patients after receiving three different treatment modalities in the ...mandible: removable partial denture (CD-RPD), complete denture (CDs), or complete overdenture supported by mini dental implants (CD-MDI). At baseline, all patients had mobile anterior teeth (1 mm or >) and missing posterior teeth in the mandible. Patients were completely edentulous in the maxilla. After treatment, patients were recalled at the 3-month and the 2-year post-treatment period.
A total of 176 patients participated (CD group, n=68; CD-RPD group, n=58; CD-MDI group, n=50). Self-reported CF was assessed using the Chewing Function questionnaire (CFQ), The OHRQoL was evaluated using the OHIP14 questionnaire, which the patients completed 1. before treatment, 2. three months after treatment, and 3. at the 2-year post-treatment stage.
The OHRQoL and the self-perceived CF significantly improved in all groups after treatment (p<0.01). The highest improvement of a CF was recorded in the CD-MDI group. The OHRQoL was significantly higher in the CD-MDI group in comparison to the CDs group after treatment (p<0.01). At the 2-year post-treatment stage, self-perceived CF significantly further improved in the CD-MDI group, while it worsened in the CD and the CD-RPD groups (p<0.01). The same pattern was recorded for the OHIP14 summary scores. The highest amount of denture repairs and adjustments was recorded in the CD-RPD group, although maintenance was also demanding in the CD-MDI group.
Within the limitations of this study, rehabilitation with mandibular MDI retained overdenture can be considered as preferred treatment with the constant improvement of OHRQoL and a chewing function in comparison to mandibular CD or mandibular RPD option in patients with mobile anterior mandibular teeth.
Three types of organic solid‐state reactions, dimerizations, dissociations, and Z‐E isomerizations were investigated by using the transformations of aromatic C‐nitroso compounds in crystalline solids ...as a convenient molecular model. Here we propose a conceptual frame for solid‐state organic reaction mechanisms by examining activation parameters obtained from kinetic measurements under specific experimental conditions. The possibility of the appearance of a sort of short‐lived intermediate liquid phase that constitutes a critical condition for initiating chemical reaction in crystalline solids, similarly to the mechanism for the thermal solid‐state reactions proposed by Paul and Curtin is discussed. The analogy of the proposed concept with the recent hypothesis about the variable rigidity/softness of the reaction cavity in the enzyme reactions, and with the newest molecular dynamic simulation studies of solid phase transformations was considered.
The role of the rigidity/softness of the reaction cavity in the mechanisms of organic solid‐state reactions was investigated by measuring activation parameters of interconversions of aromatic nitroso/azodioxides structures in crystalline solids. The results obtained suggest possible analogies between the reaction mechanisms in crystalline solids and in other condensed media.
Serious consequences of long-term complete denture wearing may be extreme residual ridge atrophy and a reduced area of keratinized oral mucosa of a denture-bearing area. This paper presents five ...clinical cases of extreme mandibular ridge atrophy, rehabilitated by means of mandibular overdentures retained by short mini dental implants. The patients had a reduced mandibular bone volume in the interforaminal region, bone height less than 10 mm, and buccolingual bone width less than 4 mm. In order to avoid bone augmentation, patients received four short mini dental implants (MDIs) (6 or 8 mm long; 2.0 or 2.5 mm wide) for the support of mandibular overdentures, which is a new rehabilitation option. After insertion, the MDIs were early loaded with new mandibular overdentures reinforced with the CoCr framework. The patients have been wearing their overdentures for 2 years. One MDI broke during insertion and a new one was added. One patient lost one MDI but successfully continued to wear the overdenture retained by the remaining three MDIs. Mean marginal bone loss (MBL) was 0.20 ± 0.19 mm. Patients significantly improved their OHRQoL and chewing function by reducing the summary scores of the OHIP-14 and the chewing function questionnaires. The improvements remained unchanged throughout the observation period.
This is a case of a 35-year-old patient who was selected to participate in the humanitarian project of a complete oral rehabilitation and quality of life improvement. The project was carried out by ...the dean, professors, teaching assistants and students at the Faculty of Dental Medicine and Health in Osijek. Patient's oral cavity status was incongruent with his age due to the extensive inflammatory disease and active caries on multiple teeth. Further progression of dental disease in this patient would have led to a complete loss of function, alveolar ridge resorption and edentulousness of the both laws. Clinical examination revealed the following: decay of the teeth 18, 13, 12, 23, 33, 43 (FDI system), dental attrition of teeth 32, 31, 41, 42, root remnants 15, 14, 11, 24, 26, 27, 38, 37, 36, 35 and 34, periodontitis and periapical periodontitis. Extensive dental reparative work has been done in this patient and he was prepared for the upcoming prosthetic work.

Ovo je slučaj 35-godišnjega pacijenta koji je izabran za sudjelovanje u humanitarnom projektu s ciljem cjelovite oralne rehabilitacije i poboljšanja kvalitete života koja je pokrenuta od strane dekana, profesora, asistenata te studenata Fakulteta za dentalnu medicinu i zdravlje u Osijeku. Stanje pacijentove oralne šupljine nije bilo u skladu s njegovim godinama zbog opsežne upalne bolesti i aktivnoga zubnog karijesa na mnogima od preostalih zubi. Daljnja progresija dentalne bolesti dovela bi do potpunoga gubitka funkcije, resorpcije alveolarnoga grebena te kompletne anodoncije obje čeljusti. Kliničkim pregledom ustanovljeno je sljedeće: infektivna bolest karijes na zubima 18, 13, 12, 23, 33, 43, dentalna atricija zuba 32, 31, 41 42, zaostali korjenovi na mjestu zuba 15, 14, 11, 24, 26, 27, 38, 37, 36, 35 i 34 te parodontitis i periapikalni procesi. Na ovom pacijentu obavljeni su opsežni dentalni reparativni zahvati koji su ujedno činili pripremu za daljnji protetski rad, koji je također u planu kao dio ovoga projekta.
All sporting activities have an associated risk of orofacial injuries due to falls, collisions with players, devices, and hard surfaces. The purpose of this investigation was to determine is there ...alteration of condylar path and frontal guidance values in athletes with and without orofacial injuries. The sample consists of 34 athletes who were divided into two groups (Control and Examines group). "Control group" consists of 11 athletes without data of macrotrauma of the stomatognatic system (athletes who didn’t get blow to the face). The second group is "Examines group" witch consists of 23 athletes with macrotrauma (athletes who get blow to the face), 11 of them were athletes with macrotrauma on the right side of jaw and 12 of them were athletes with macrotrauma on the left side of jaw. Athletes with anamnestic blow to the jaws, immediately after injury, have had stiffness/pain of masticatory muscles, pain in region of TMJ, and limitation of jaw movements. But all symptoms diminished and finally were gone after some days or weeks after injury. In time of investigation all of them were completely without any symptom of temporomandibular dysfunction according to RDC/TMD protocol, and were completely satisfied with function of their stomatognathic system. Athletes with macrotrauma have limitation of Bennett angle on the one side while on the opposite side Bennett angle is larger than the average values given in literature. As conclusion, if athletes with macrotrauma need prosthetic therapy, without individual articulator adjustment, prosthodontics work can cause iatrogenic interference. That interference during time may cause temporomandibular dysfunction. All patients need individual approach to their stomatognatic system, and only in that way damage to the system can be avoided.
