Clinical and practical aspects of the gingival smile. A questionnaire-based survey.

Thu, 14 Dec 2023 00:00:00 GMT

Introduction: One of the main elements of facial esthetics is represented by the smile. A harmonious proportion between the elements of facial esthetics is an important subject of interest in dentistry. Aim of the study: This research aims to evaluate the impact of the gummy smile on future dental practitioners. Materials and Methods: A survey containing 16 questions was designed to find out the students’ perceptions about the ideal smile and if the gingival smile is considered youthful or unpleasing. The impact on their self-esteem, their willingness to change the gummy smile or not, the nonsurgical and surgical methods of treatment were also evaluated. Results: 212 answers were recorded and analyzed. Nearly three quarters (70.3%) of the respondents believe that having a gummy smile is unesthetic, while only 29.3% considered it to be a sign of youth. Self-esteem can be affected by having a gingival smile, but, according to the results, most of the students (45.8%) said that their daily lives have not been affected by it, 40.6% said that in a small amount, 10.4% said that their self-assurance has been very affected and only 3.3% admitted that the gummy smile distressed their confidence. When asked if they were willing to correct their gingival smile, 51.4% were open to improving it while 48.6% would not change it. Conclusions: Among dentistry students, excessive showing of the gums is believed to be unesthetic rather than a sign of youthfulness. The respondents are generally not affected in their daily life by having a gummy smile. Education regarding the methods of correcting it still needs to be addressed amongst future dental practitioners.

Systematic Review Regarding The Difference In Dental Plaque Accumulation Associated With Fixed Orthodontic Retainers And Vacuum Formed Removable Retainer.

Thu, 14 Dec 2023 00:00:00 GMT

Introduction: Orthodontic retention is fundamental to prevent tooth relapse after the treatment. Plaque accumulation is a serious concern, affecting periodontal health. In this study, the effects of fixed retainers with removable vacuum formed retainers on plaque accumulation by evaluating the Plaque Indices were compared.Aim of the study: The aim of the present systematic review is to comprehend which orthodontic retainer between fixed retainers and the removable vacuum formed retainers results in the least amount of plaque accumulation.Material and Methods: For evaluation a literature review was carried out by all the reviewers by consulting PubMed, ScienceDirect, The Lancet, Sciendo, and Google Scholars electronic databases for biomedical and health literature. The articles were selected from 2017 onwards with the restriction of the English language.Results: 5 studies were selected, reporting on a total of 249 patients both males and females who after debonding orthodontic appliances followed up with either a fixed or vacuum formed retainer.Conclusion: Within their limits, the results seem to show that patients who wear Vacuum Formed Retainers tend to accumulate less plaque than the ones that wear Fixed Retainers. However, subsequent studies are required to address this matter and draw a definitive conclusion.

Quantification of flowability and hydrophilicity of elastomeric impression materials.

Thu, 14 Dec 2023 00:00:00 GMT

Introduction: Flowability and hydrophilicity are essential properties of accurate impressions and casts. Aim of study: This study aimed to quantify these characteristics of elastomeric impression materials. Material and Methods: A total number of eight impression materials, including vinyl polysiloxane (PVS), polyether (PE), and condensation silicone (CS) were thoroughly investigated in this study. The flowability of elastomers was proven with the shark fin test (SFT), and the hydrophilicity was determined with contact angle (CA) measurements. Results: The shark fins’ (SF) of VPSs presented 11.57 mm (SD 3.49), while the PE 11.37 mm (SD 5.06) and CS 8.1 mm average values. Some of the products showed better flowability. Based on 128 measured CAs, the examined polyethers had the lowest CAs which indicate good hydrophilicity. Conclusions: A good performance of an impression material in one of the involved tests (SFT and CA) does not mean a similar result in the other analysis. All investigated impression materials could be considered hydrophilic as their CA was lower than 90°. The SFTs of light-bodied VPSs and PEs suggest reliable use of them in dental practice.

Study on the conditions of color determination in dentistry.

Thu, 14 Dec 2023 00:00:00 GMT

Introduction: Several variables can impact the choice of shade. Having a thorough understanding of these factors and following the proper selection technique is crucial for achieving favorable esthetic results. Aim of the study: To review the characteristics of esthetic perception of teeth in different lighting conditions, by individuals with different levels of experience in dentistry. Material and methods: Thirty volunteers, dentistry students, and general dentists were recruited. The participants were asked to determine the color of 4 mock-ups containing artificial teeth, under standardized conditions. Therefore, the samples were introduced in a custom-made box and illuminated by two different light conditions (4300 K and 5500 K), and three different colors (black, gray, and pink) were selected as background colors. Results: Our results showed a statistically significant difference between the two examined light conditions, the number of correct color determinations was significantly higher under the light with a color temperature of 5500K (p<0.00001). It can be seen that the gray background color proved to be statistically significantly more beneficial than the black and pink background colors. Conclusions: Among dentistry students and practitioners, environmental changes that affect shade determination have been demonstrated. Further research is still necessary regarding the perception of the esthetic expectations of dental treatments for color determination.

Comparative oral health outcomes before and after periodontitis treatment: Scaling and root planning alone versus Nd: YAG Laser Assisted New Attachment Procedure.

Thu, 14 Dec 2023 00:00:00 GMT

Introduction: Periodontitis is a multifactorial condition that impacts the support tissues of the teeth. The purpose of the research was to correlate the results obtained in the treatment of patients with at least stage II periodontitis by scaling and root planing alone (SRP), or by the laser-assisted new attachment procedure (LANAP), and to assess the outcomes and patients' perceptions regarding the influence of these therapies on their quality of life by using The Oral Health Impact Profile-14 (OHIP-14) questionnaire.Materials and methods: The oral cavities of 15 patients were divided into quadrants, and, according to the inclusion and exclusion criteria, two quadrants were allocated to one of the groups after the effectuated therapy: SRP or LANAP. The patient’s periodontal status (VPI, PPD, BOP, and CAL) was assessed and filed in a periodontal chart at baseline and 6 weeks after the implementation of the treatments, along with the OHIP-14 questionnaire. SRP was conducted for the first group of patients, in the selected quadrant and in the two remaining quadrants that were not included in the study. The LANAP protocol was applied to the quadrant belonging to the second group (LANAP) using a 1064 nm Nd: YAG laser (Lightwalker AT-S, Fotona®, Slovenia).Results: The results showed that both noninvasive treatments are effective in diminishing VPI, PPD, BOP, and CAL in periodontal patients, and the scores obtained 6 weeks after the end of the periodontal treatments determined the improvement of the patient's perception in the questionnaire.Conclusion: Both the association of the Nd: YAG laser with scaling and root planing (LANAP) and SRP alone provided safe and efficient outcomes, resulting in high levels of satisfaction among patients at 6 weeks after treatment.

Evaluation of the therapeutic performance of ICON infiltration resin in the treatment of White Spot Lesions in esthetic dental areas. Clinical Report.

Thu, 14 Dec 2023 00:00:00 GMT

White spot lesions, pathologically characterized by enamel demineralization, present a significant challenge in dentistry. Notably, intervention at the white spot stage is crucial to impede further lesion progression. Recent advances studies have demonstrated the effectiveness of flowable resin infiltration as a minimally invasive alternative to traditional treatment modalities. This technique allows for the concurrent treatment of multiple lesions in a single appointment, circumventing the necessity for local anesthesia or extensive cavity preparation. Clinically, this method has shown consistent stability, evidenced by maintained enamel integrity, enhanced rigidity, and preservation of adjacent healthy dental tissues. Additionally, the aesthetic outcomes of this approach are noteworthy, with a gradual diminution of lesion visibility over time. The present case report elucidates the long-term clinical outcomes and the efficaciousness of the Icon kit in the targeted management of specific white spot lesion pathologies.

Evaluation of the tensile properties of polished and unpolished 3D SLA- and DLP-Printed specimens used for surgical guides fabrication.

Fri, 09 Jun 2023 00:00:00 GMT

Introduction: The fundamental mechanical properties of 3D printed surgical guides used in orthodontics represent an important indicator for the accuracy of the insertion of skeletal anchorage devices. The tensile strength of devices printed by stereolithography (SLA) and digital light processing (DLP) methods, respectively, is influenced by factors such as finishing process.Aim of the study: This study illustrates a comparison of the tensile strength in two different types of 3D printed devices (SLA, DLP respectively) undergoing or not a standard process of polishing.Material and methods: Twenty-four specimens obtained according to ASTM D638-14 (Standard Test Method for Tensile Properties of Plastics) were used for the evaluation of tensile strength. Four groups of 6 samples from each category were created: SLA polished, SLA unpolished, DLP polished and DLP unpolished. After removing the support, finishing was performed to obtain smooth surfaces, according to the manufacturer’s recommendation. Type V specimen was used to perform tensile tests in accordance with the standard procedures ASTM D638-14 which recommends at least five specimens to be tested for each sample.One-way analysis of variance (ANOVA) and t-test showed statistically significant results at p < 0.05. SPSSv17 software was used for statistical analysis of the numerical variables, and also descriptive statistics were performed.Results: The measurements included: tensile strength (maximum load), tensile stress at maximum load and tensile strain at maximum load. The maximum load (tensile strength) of the polished specimens was lower, both for the SLA and DLP, with no statistical significance results.Conclusions: The conclusions indicated differences between maximum load and tensile stress at maximum load between polished and unpolished specimens, in both SLA and DLP groups. Althought the polishing process reduces the tensile strenght, the data analysis did not present statistically significant results.

The influence of the prosthetic abutments colour in the aesthetics of the frontal teeth. A case report.

Sat, 20 May 2023 00:00:00 GMT

Introduction: Prosthetic restorations in the frontal teeth, in addition to functional and prophylactic requirements, must respond in a special way to aesthetic needs. This desideratum is a challenge, especially when the support for the future prosthetic parts is not characterized by a uniformity of color. This paper wants to highlight the importance of the color of prosthetic abutments, in the case of single restorations, for the frontal teeth. Case presentation: This manuscript presents the clinical case of a patient, with different prosthetic abutments, namely: a hybrid implant abutment - titanium and zirconium (lateral incisor - 1.2), nonvital natural teeth (central incisors – 1.1 and 2.1) and a vital natural tooth (lateral incisor – 2.2). Three single ceramic crowns on zirconium were confectioned, one with implant support and the other two on dental support, and a veneer for the vital lateral incisor. Conclusions: The prosthodontist must develop the best prosthetic solution for each individual case, together with the technician, so that the aesthetic results are not negatively influenced by the different colors of the existing prosthetic abutments.

The link between Noncarious Cervical Lesions (NCCL) and gingival recession. Etiology and treatment. A narrative review.

Wed, 08 Mar 2023 00:00:00 GMT

Noncarious cervical lesions (NCCL) have a multifactorial etiology. The terms abfraction, abrasion, and erosion are also used to describe the same lesion. NCCLs can lead to gum recession which is one of the most frequent gingival defects. NCCLs generally also involve loss of tooth structure. Therefore, treatments should be planned and performed in an interdisciplinary manner. When NCCL is minimal, the choise to use simple direct restorations is the main therapeutic option. If it is serious, microsurgical treatment or, more precisely, interdisciplinary treatment might be necessary. Root coverage by microsurgical methods is the most challenging esthetic procedure. There are many techniques available of which we must always choose the method that can ensure and control root coverage in the long term.

Total and partial magnetic retained overdenture. A clinical report.

Mon, 27 Feb 2023 00:00:00 GMT

An overdenture is a denture supported partly by soft tissues and partly by retained teeth or implants. Magnetic tooth-retained overdentures are used to increase support, retention, and stability but also prevent alveolar ridge resorption. Magnetic attachments increase the retention of partial or complete dentures regardless of the path of the insertion and, in addition, can be used for abutment teeth with periodontal disease. This paper discusses two oral rehabilitation cases with total and partial tooth-retained overdenture.

Cephalometric evaluation of adenoids and upper airway.

Mon, 26 Dec 2022 00:00:00 GMT

Cephalometric analysis performed on lateral X-ray allow orthodontists to evaluate soft tissues as well. Enlargement of adenoids, changes of the position of the tongue can be diagnosed parallel with skeletal assessment.Our purpose was to investigate the skeletal growth direction and the posterior airway depth in mouth breather patients and to underline the importance of a complex cephalometric analysis prior orthodontic treatment.30 mouth breather patients were selected from our database (17 boys and 13 girls, age 10.8±1.2), in every case ENT examination confirmed the hypertrophy of adenoids. From the same database 30 patients with normal breathing pattern (17 boys and 13 girls, age 11.1±0.9) for the control group. For every patient, the size of the adenoids, the depth of the palate and the position of the tongue. After filtering out the outliers in GraphPad-InStat system, standard deviation (±SD) was calculated, descriptive analytical statistics were performed.Statistically significant differences were recorded regarding: 1.) the distance between adenoid vegetation and the palate (p=0.014, mouth breathers mean 9.76 ± SD 3.04; control group mean 14.38 ± SD 4.41), 2.) the distance between Sella and the adenoids (p=0.186, study group mean 33.39 ± SD 4.39; control group mean 28.38 ± SD 8.91), 3.) adenoidal-nasopharyngeal ratio (p = 0.05).Cephalometric evaluation of adenoids revealed considerable enlargement of this in mouth-breather children, meanwhile upper airway constriction will appear in the same group. Depth of the palatum will increase when breathing pattern is modified.

Dental photography: Why? What? How? Part 1 Why? The role of dental photography in daily practice.

Mon, 26 Dec 2022 00:00:00 GMT

Digital Dental Photography (DDP) represents a must-have instrument for all dentists in their daily activities. Nowadays, DDP represents a tool that is no longer reserved for a select small number of dentists but is accessible to every practitioner. Although the number of dentists who use DDP daily is increasing, there is much hesitance, many questions, and resistance regarding the introduction of dental photography in daily practice.This series of articles aims to demystify all the misconceptions related to the DDP and offer readers a transparent image of how DDP can become the most powerful tool for their offices. All the “mysterious” terms related to the DDP will be explained, and simple protocols that can be easily incorporated in any dental office in daily practice will be presented.This article is the first in a five-part series dedicated to DDP.Part 1 defines the role of DDP in daily practice covering the four significant indications: documentation, communication, education, and marketing.

Clinical outcomes of predoctoral implant dentistry education: A Systematic Review.

Mon, 26 Dec 2022 00:00:00 GMT

Objectives: To systematically synthesize the status of predoctoral implant dental education in terms of clinical outcomes including implant success and survival of them when placed by predoctoral students.Materials and methods: A thorough search was carried out up to February 2019 using Medline (OVID), EMBASE, ERIC, and Web of Science electronic databases. In addition to this, bibliographies of the potentially eligible articles were searched manually. Abstracts that seemed to satisfy the initial selection criteria were selected for the recovery of the full text. The full-text risk of bias assessment was then done, in line with the selection criteria by two reviewers. The selected articles were evaluated using the Joanna Briggs Institute (JBI) Critical Appraisal tools. The GRADE approach was adapted, but not validated, for observational studies to assess the certainty of evidence.Results: Overall, 15 articles were included. Most of the reported implants were used to support mandibular overdentures or single unit implants and their survival rates were found to be generally favorable. Only a few studies also used patient satisfaction surveys which displayed overall satisfaction, suggesting that the dental implant treatment may be adequately provided in school settings.Clinical significance: The success and survival of the implant’s type done in an undergraduate classroom setting is indicative of the undergraduate dental implant curriculum. Based on this work, it can be concluded that the success and survival of such implants appear to be reasonable and most of the patients getting an implant at the school were satisfied.

Current status of predoctoral implant dentistry education – student’s didactic performance and self-assessment: A Systematic Review.

Mon, 26 Dec 2022 00:00:00 GMT

Objectives: To describe the current state of predoctoral dental implant education in terms of educational outcomes and the student’s perception of the associated curriculum. Methods: A database search was conducted using Medline (OVID), EMBASE, ERIC (Education Resources and Information Centre) and Web of Science electronic sources. Two reviewers thoroughly reviewed the papers in accordance with the specific selection criteria after carefully choosing the abstracts that seemed to meet the initial selection criterion for full article retrieval.Results: 15 articles were included, which were divided into two distinct groups: those that addressed educational outcomes and those that addressed students’ perceptions. Knowledge was assessed by questionnaire surveys, and it was found that most of the students were poorly to moderately well informed. There was a positive increase in student perception after taking the implant courses.Clinical significance: Although predoctoral education in most dental schools across the world now includes implant dentistry as a core component, the degree of integration varies greatly. To increase the proficiency of predoctoral students around the world in performing implant treatments, it is necessary, according to this systematic review, to create a uniform, well-structured predoctoral implant curriculum and guidelines that include didactic, laboratory, preclinical, and clinical components.

The hematogenous marrow tolerance when being in direct contact with the titanium implant.

Mon, 26 Dec 2022 00:00:00 GMT

Introduction: The titanium implant represents a foreign body for the organism in which it is inserted, and it will never be accepted as an intrinsic structure. However, research has shown that it is very well supported both by soft and hard tissues, including here the limitrophe implant tissues.Aim of the study: The aim of this study was to test the tolerability towards the titanium implant inserted in direct contact with the hematogenous marrow.Material and methods: Titanium implants with the length of 10 mm and the diameter of 2 mm were inserted in the diaphysis of the femora bone of 10 male rabbits with the age of 10 months. At these particular dimensions, the implant exceeded the depth of the bone wall with more than half its length, taking direct contact with the hematogenous marrow from the marrow channel.Results: Seven days after the implants insertion, the histologic examination revealed the fact that the hematogenous marrow had a very good lenience towards the titanium implant, meaning that it did not lead to any immunological rejection reactions, nor to pathological processes or the tendency of proliferation of unwanted tissues like conjunctive fibrous tissue. In these conditions, the pre-implantation reparatory processes fully benefited of the hematogenous marrow support, which, not being altered in any way, offered cells and stimulant factors, of the same intensity, throughout the entire experimental period.Conclusions: The high tolerance of the hematogenous marrow to the titanium implant assures special conditions for the peri-implantation reparatory processes which take place at a speed that cannot be competed against by other stimulant modalities. This stimulant modality of reparatory processes cannot be applied in all situations, but only when working on healthy bones that contain hematogenous marrow, therefore the practical applicability relates especially to the dental interventions of implant prosthesis.

The impact of covid-19 on a patient with a severely compromised permanent maxillary central incisor.

Mon, 04 Jul 2022 00:00:00 GMT

The SARS-CoV-2 pandemic situation led to public health measures that forced patients to remain isolated and take steps to prevent the dissemination of the virus. Many of these patients were unable to attend to the dental services or delayed seeking dental care due to a lack of private services and concerns about the SARS-CoV-2 outbreak, which in many cases complicated their situation.This case report describes the long-term clinical outcome of an endo-periodontal periapical lesion with associated bone defect of a maxillary central incisor in an esthetically demanding, systemically healthy patient, who neglected dental treatment during the pandemic outbreak. Treatment procedures included primary endodontic treatment of the periapical lesion and cause-related therapy aimed to control the infection in the rest of the mouth. Clinical examination at the 1-year recall revealed clinical attachment gain with shallow residual probing pocket depths and a slight increase in gingival recession. The esthetic appearance of the treated tooth was improved via a zirconia-ceramic crown. The present case report suggests that successful periodontal and esthetic results can be accomplished and maintained for at least 2 years after treatment of an apparently hopeless tooth with extremely compromised endoperiodontal conditions.
