Multiple Inflammatory Fibrous Hyperplasia in Upper Lip: A Case Report

Aims: This study aimed to report a case of multiple inflammatory fibrous hyperplasia in the upper lip, resulting from the association of lip sucking habit and the use of orthodontic appliance, treated with high-powered laser. Presentation of Case: A 42 years-old male patient, anxious, presented with five lesions in upper lip in close contact with dental appliance. Also, he had a habit of sucking his lip. After the removal of the appliance, it was performed a surgery using a diode laser (Thera Lase Surgery λ=808 nm, P=2.5 W). Discussion: The removal of the traumatic etiological agent is essential for the treatment of proliferative lesions, such as hyperplasias. After removal, if there is no complete regression of a small hyperplasia, surgical removal will be necessary. Diode surgical laser is a good alternative, due its advantages. Conclusion: It is very important to advise patients with harmful habits, as lip sucking, that with the persistence of the habit, new lesions will arise again. Monitoring psychological factors is also essential.

Effects of Fixed and Removable Space Maintainers on Dental Plaque and DMFT/dft Values

Purpose: Space maintainers are important for the health and placement of children’s primary and permanent teeth. However, plaque and caries levels can be negatively affected when a dental appliance is in the mouth. This study aims to evaluate the oral health of pediatric patients that have space maintainers applied as a result of early tooth loss. Methods: This study included 100 systemically healthy patients between the ages of 4-15 years that were treated with space maintainers due to early loss of teeth. Decayed, missing, filled tooth index values and dental plaque status of the participants were recorded. Controls were performed in the 6th and 12th month. The index results were compared and evaluated statistically using ANOVA and paired-t-tests. Results: A total of 116 space maintainers, including 36 band and loops, 16 lingual arches, 21 palatal arches, 43 removable appliances, were evaluated in the study. Statistically significant differences were found between the pre-treatment and post-treatment index values (p<0.001). In the group of band and loops and removable space maintainers; the increases in DMFT/dft values of 6th month and 12th month according to initial DMFT/dft values were statistically significant (p<0.05). For plaque index, the increase in 12th month of all types of appliances were found statistically significant (p<0.001). The greatest increase in plaque index level was seen in the teeth of patients that had been treated with a lingual arch. Conclusions: Incompatible space maintainers can lead to caries, increased plaque accumulation, demineralized areas, and periodontal problems. The accumulation of plaque and difficulty of cleaning the teeth, especially in the fixed space maintainers, negatively affects the health of teeth. For this reason, good oral hygiene should be provided to patients and controls should be regularly performed.

CLASSICAL AND MODERN TELESCOPIC CONNECTION SYSTEMS

The purpose of this work is to identify, evaluate and compare the scientific views on the role of telescopic crowns in fixing partial removable dentures. Materials and methods. Analytical study of relevant scientific sources on the issue of the restoration of dentition defects with dentures retained by telescopic crowns. To replace defects in dentition, partial removable dentures are the best option due to their optimal ratio between such parameters as aesthetics, quality and price. The analysis of the relevant literature has demonstrated that using telescopic attachment is the best choice for restoring chewing efficacy, functioning and aesthetics of the maxillofacial system, for removing the deformities of the occlusive surface of the dentition and traumatic occlusion in patients with partial loss of teeth. All of the above mention demonstrates that telescopic dentures have many advantages supported by observing the dynamics of follow up period in individuals who underwent the correction with partial removable dentures and by the opinions of experts. Having analyzed numerous reports of national and international researchers, we can conclude that the advantages of retaining removable dentures by telescopic systems are determined by a number of their capabilities that include the distribution of chewing pressure on the abutment teeth in accordance with their longitudinal axes, providing positive effect on the periodontium and reducing the atrophy of the tissues of the prosthetic bed compared with other retaining systems, as well as by providing a "perfect" aesthetic appearance of the dental appliance.

An Unusual Etruscan Gold Dental Appliance from Poggio Gaiella, Italy: Fourth in a Series

Among the 20 known ancient dental prostheses from etruscan archaeological contexts in an unusal example that was recovered for Poggio Gaiella, Italy. The form and construction technique used in making the Poggio Gaiella piece suggests that it was used as a restraining band to hold loose teeth in place within a maxilla. The possibility that these appliances provide evidence for early cases of leprosy rather than tooth evulsion is discussed.

Comparison of virtual and physical dimensions in AM resin dental devices and fit of devices with conventionally produced base plates

Purpose The purpose of this study is to develop and apply clinically relevant methods of analysing the accuracy of dental appliances fabricated using additive manufacture (AM) compared to the computer-aided design (CAD) geometry. The study also compared fit between conventionally laboratory-fabricated and AM-produced base plates. Design/methodology/approach The techniques were applied to two types of dental devices where AM fabrication methods could foreseeably be used as an alternative to laboratory production. “L” and cubic shapes of defined dimensions and spatial locations were positioned on the devices which were fabricated using AM. For assessing the dimensions, the “L” and cubic shapes were then measured on the physical builds ten times and compared to the CAD model. To assess the fit of AM and lab-produced devices, three upper and three lower conventionally fabricated acrylic base plates were compared to three upper and three lower plates. Silicone impression material was allowed to set between the casts and the base plates which filled any discrepancy between the two surfaces. The thickness of this silicone media was measured ten times at five different points on each base plate type and the results compared. Findings The results indicated that the evaluated CAD/AM technique is able to produce dental appliance components that are consistent with tolerance levels that would be expected with conventional methods of baseplate design. This research demonstrated that a fully CAD/AM methodology represents a potentially viable alternative to conventional lab-based methods for two types of dental appliances. Originality/value This work is original. The authors do not believe any previous papers similar to the one submitted have been published.
