Accuracy of intraoral scanners based on jaw curve and inter-implant distance

Tue, 03 Sep 2024 00:00:00 +0700

Background: In digital dentistry, the intraoral scanner (IOS) is the primary data-collecting device. The data must be accurate to prevent undesirable stresses and technological difficulties resulting from prosthetic misfits. The span length of restorations influences the accuracy of IOS impressions. Purpose: This research aimed to compare the accuracy of virtual models scanned by different IOSs to determine whether jaw curvature and inter-implant distance affect accuracy. Methods: Four mandibular edentulous models were prepared by replacing the site of the missing tooth with an implant. The prepared holes were drilled at 7mm, 14mm, 21mm, and 28mm. Five scans for each model were taken with a desktop laboratory scanner as a reference model and with Trios3Shape and 3Disc Heron IOSs to evaluate trueness and precision (T&P). The scans were saved as standard triangulation language files and statistically analyzed at a level of significance (P ≤ 0.05). Results: There was a significant difference between the IOSs in inter-implant distances (P < 0.05). The greatest distortion was reported in the 21mm and 28mm groups for both scanners (P ≤ 0.05), while the lowest distortion was observed in the 7mm and 14mm groups for the Trios3Shape scanner. Conclusion: Jaw curvature and inter-implant distance impacted the accuracy of the IOS. Distortion and reduced reproducibility of T&P increased with jaw curve and inter-implant distance. The Trios3Shape IOS showed maximum accuracy at 7mm and 14mm inter-implant distances, while the 3Disc Heron IOS produced significant distortion of trueness at 21mm and 28mm inter-implant distances.

Casein phosphopeptide-amorphous calcium phosphate varnish versus dentin desensitizer in the treatment of non-carious dentin hypersensitivity

Tue, 03 Sep 2024 00:00:00 +0700

Background: Dentin hypersensitivity (DH) is one of the most common conditions clinicians encounter in clinical practice. New techniques are continuously being set forth to treat this condition. In recent times, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has garnered attention owing to its ability to improve remineralization and prevent enamel demineralization. Consequently, it has been indicated as an advanced treatment for DH. Purpose: This clinical trial aims to assess the efficacy of a CPP-ACP varnish in the management of non-carious cervical hypersensitivity and compare it with that of a dentin desensitizer. Methods: Patients between the ages of 20 and 65 years who reported to our institute with complaints of DH were selected for this study. Forty teeth were chosen for this study and randomly assigned to two groups. The test group was treated with a CPP-ACP varnish (MI Varnish®, GC Corporation, Japan), while the control group was treated with a dentin desensitizer (Gluma®, Heraeus-Kulzer, Germany). Dentin hypersensitivity assessments were conducted during pre-treatment, immediately following treatment, and 2 and 4 weeks after treatment. Statistical analysis was performed after data collection. Results: An intragroup comparison showed both the CPP-ACP varnish and the dentin desensitizer achieved a maximum decrease in sensitivity in the time interval from baseline to post-op, and these desensitizing effects were sustained through the second and fourth week following treatment. An intergroup comparison revealed no statistically significant difference in sensitivity between the two groups at different time intervals. Conclusion: It could be concluded that CPP-ACP varnish and dentin desensitizer possess similar efficacy in the treatment of DH.

The effect of epigallocatechin gallate on Streptococcus Gordonii biofilm formation

Tue, 03 Sep 2024 00:00:00 +0700

Background: Dental caries, as a primary disease in dentistry, is strongly influenced by the presence of biofilms. One of the Gram-positive bacteria that acts as an initiator in the biofilm formation process is Streptococcus gordonii. As the primary catechin in green tea, epigallocatechin gallate (EGCG) is easily found in our daily lives, and it has a broad spectrum of antimicrobial effects. Several studies have revealed that EGCG inhibited the growth of Gram-positive bacteria, including inhibiting biofilm formation by damaging the bacterial cell wall and reducing glucosyltransferase activity. However, there is still limited information that explains the effect of EGCG on S. gordonii bacterial biofilms. Purpose: This study aims to analyze the effect of EGCG in inhibiting the formation of S. gordonii bacterial biofilms. Methods: This study was an in-vitro experimental laboratory study, with samples divided into five groups, namely, the group containing BHIB-bacteria, the BHIB-bacteria-5% sucrose groups, and the treatment groups containing BHIB-bacteria-5% sucrose-EGCG with concentrations of 12.5%, 6.25%, and 3.125%, respectively, incubated for 24 hours. The data was analyzed using the Kruskal–Wallis test. Results: There was a significant difference in the formation of biofilms in S. gordonii bacteria with the addition of 5% sucrose in BHIB compared with the group of S. gordonii bacteria in BHIB. The highest biofilm formation in the group containing bacteria-BHIB-5% sucrose, while the lowest biofilm formation occurred in the treatment group containing bacteria-BHIB-5% sucrose-12.5% EGCG with significant difference between the group. Conclusion: The addition of EGCG 12.5% inhibits the formation of S. gordonii biofilms.

Influence of implant number on the retention and support of mandibular overdentures

Ahmed A. Al-Bdrany, Mohammed M. Sadoon — Thu, 05 Sep 2024 00:00:00 +0700

Background: There are two distinct categories of attachments—magnetic attachments and positioner attachments—currently in use for dental implants. Many implants required for implant-retained overdentures need support from implant-retained overdentures. Purpose: The aim of this study is to evaluate the effect of different implant numbers and attachment types on the retention and support of implant-retained overdentures. Methods: This experimental work involved the utilization of a model that replicated a mandibular edentulous arch, a total of five models. Within this model, seven dental implant analogues were implanted to mimic the tooth positioning observed in the natural dentition. Thirty-five titanium dental implant analogues (Dentium, South Korea) were employed in this study. A total of ten overdenture housings were fabricated using 3D printer acrylic resin, with each housing including a specific type of attachment (magnetic and positioner attachment). These attachments were equipped with three loops that were affixed to the occlusal surface of the housing. Subsequently, three chains were connected between the loops and a force gauge testing equipment. Results: The positioner was found to be more retentive and supportive than the magnetic one in the three directions of the dislodgement test as well as under unilateral and bilateral load, according to an independent t-test comparing magnetic and positioner attachment (p<0.05). Conclusion: Depending on the method of attachment that is used, variations in implant number have varying effects on the retention and support of an implant-held overdenture.

Development of dental clinic cooperativity predictor instrument for children with autism spectrum disorder

Tue, 03 Sep 2024 00:00:00 +0700

Background: A survey to identify factors affecting the cooperation of children with autism spectrum disorder (ASD) in Indonesia is crucial for enhancing this group’s dental care, oral health, and overall quality of life. However, limited culturally relevant instruments hinder such research. Purpose: This study aims to determine the essential domain needed to design a questionnaire instrument that can predict the cooperativity of children with ASD during dental procedures. Methods: Based on the literature and existing questionnaires, the newly developed questionnaire underwent forward–back translation, before being thoroughly reviewed by an expert committee. The response format, content, and question clarity were evaluated. A cross-sectional study with 30 parents of children with ASD was randomly conducted to test the questionnaire. The validity of each question was measured by the Pearson product-moment correlation coefficient, while its reliability was assessed by Cronbach’s alpha. Results: Each question within the domain showed varying degrees of validity: reading ability (r = 0.658), daily communication (r = 0.541), involvement in social activity (r = 0.360), daily self-care ability (r = 0.506), emotional status (r = 0.426), sensory responsiveness (r = 0.615), language comprehension (r = 0.362), and permission to be touched on the head at a barbershop (r = 0.458). The questions were found to be reliable (Cronbach’s alpha, r = 0.645 > 0.306). Conclusion: As prediction tools for assessing the cooperativity of children with ASD during dental procedures, the questionnaire should include the following items: communication and reading abilities, daily self-care, social activity, emotional status, sensory responsiveness and permission to be touched on the head at a barbershop.

The effect of adding ZrO2 nanoparticles on the transverse strength and hardness of microwave-cured acrylic and heat-cured acrylic denture base materials

Marwah M. Shehab, Radhwan Himmadi Hasan, Rana Rabee Aziz — Thu, 05 Sep 2024 00:00:00 +0700

Background: One drawback of acrylic denture base materials is their liability to fracture, requiring methods to increase fracture resistance. Adding nanoparticles (NPs) represented one of these methods. Purpose: The objectives of this study are to evaluate and compare transverse strength and hardness when adding zirconium oxide nanoparticles (ZrO2 NPs) at concentrations of 0%, 3%, and 5% to heat-cured acrylic denture base materials (Ivoclare, Major) and to microwave-cured acrylic (Acron MC). Methods: Transverse strength was tested with a Universal Testing Machine (GESTER, Fujian, China), while hardness tests were conducted by using a Shore-D hardness durometer (Show, China). The 90 samples were prepared and then divided into three groups for each material. Attenuated total reflectance–Fourier transform infrared (ATR-FTIR) spectroscopy was used to analyze the microstructure. The samples were prepared following the manufacturer’s instructions for each material. Results: The results revealed that the addition of ZrO2 NPs (3%, 5%) improves the transverse strength and hardness of polymethyl methacrylate acrylic resin for both types (microwave-cured and heat-cured acrylic resins). The addition of ZrO2 NPs at 3% concentration shows the highest values for both transverse strength and hardness. The ATR-FTIR confirms no structural chemical changes with the addition of ZrO2 NPs. Conclusion: The study concludes that the incorporation of ZrO2 NPs (3%, 5%) into microwave-cured and heat-cured acrylic resins improves transverse strength and hardness.

Oral health literacy, knowledge, attitude, and oral health practices among college students at Jenderal Soedirman University

Tue, 03 Sep 2024 00:00:00 +0700

Background: Oral health literacy (OHL) has an important role as a medium for health promotion and efforts to prevent oral diseases through oral health behavior changes. Purpose: This study aims to determine OHL and its correlation with oral health knowledge, attitude, and oral health practice among college students. Methods: This cross-sectional study was conducted on 583 students of Jenderal Soedirman University in 2020, as the students come from different provinces in Indonesia. The Indonesian Oral Health Literacy Questionnaire was used to assess OHL. A self-designed questionnaire was used to assess oral health knowledge, attitude, and oral health practice. Results: Most students had good OHL, knowledge, and attitude toward oral health (90.7%, 84.6%, and 90.5% respectively). A Pearson correlation test showed a correlation between OHL and oral health knowledge (p = 0.044) and attitude (p = < 0.001). The Fisher exact tests showed a correlation between OHL and snacking frequency, tooth-brushing frequency, tooth-brushing time, and toothbrush changing time. The better the OHL, the better the knowledge and attitude. There was no correlation between OHL and sweet food eating frequency, the use of cleansing aids, dentist visit frequency, and the first action taken when experiencing toothache. Conclusion: OHL has a correlation with oral health knowledge and attitude. However, OHL is only related to some oral health practice indicators. The results of this study are expected to be taken into consideration when formulating strategies to improve oral health within the university.

Validation of the Jamaican version of the Oral Health Impact Profile (OHIP-14) in adults: JAM-OHIP study

Fri, 13 Sep 2024 00:00:00 +0700

Background: The Oral Health Impact Profile (OHIP-14) is a widely used tool for measuring the effects of oral health-related quality of life (OHRQoL). However, the validity of the OHIP-14 in the Jamaican context, referred to as the Jamaican Oral Health Impact Profile (JAM-OHIP), has yet to be established. Purpose: To determine the validity of the Jamaican language version of the OHIP in evaluating the OHRQoL of Jamaican adults. Methods: The original English version of the Oral Health Impact Profile (OHIP-14) was translated into the Jamaican language using forward and backward translation. The JAM-OHIP was used to evaluate the OHRQoL of 236 individuals at the University of the West Indies Dental Polyclinic. The overall fit was checked using a chi-square test (p > 0.05), comparative fit index (CFI), Tucker–Lewis index (TLI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR). Results: More DMFT (p < 0.01) was associated with high JAM-OHIP scores, and the most impacted domain was physical pain. Cronbach’s alpha and the standardized item alpha for the JAM-OHIP were 0.82. The overall fitting results for the CFA were χ²(68) = 80.558, p = 0.142, and χ²/g.l. = 1.185. The CFI and TLI were 0.996 and 0.994, respectively. The SRMR was 0.072 and the RMSEA was 0.028 (CI_95% = [0.000; 0.050]) p = 0.953. Conclusions: The JAM-OHIP instrument was shown to be reliable and valid for the assessment of OHRQoL in the Jamaican adult population.

Evaluation of foot analysis in the presence of dental malocclusion: A systematic review

Tue, 03 Sep 2024 00:00:00 +0700

Background: Previous studies have reported that the imbalance of occlusion, cervical spine, length of the limb, and asymmetric leg length are related to the presence of muscle compensation. These issues influence some strategies in orthodontic diagnosis for developing an updated stomatognathic system over multidisciplinary care issues. Purpose: This study aimed to obtain orthodontic findings and an orthopedic relationship between foot posture/function and dental malocclusion based on cross-sectional studies. Review: Some findings about postural system disequilibrium in static and dynamic foot postural related to occlusal changes have been reported following the mixed dentition phase. From 248 articles, 5 articles were selected and assessed with the Joanna Briggs Institute critical appraisal cross-sectional checklist and analyzed. Conclusions: Although the selected eligible articles demonstrated a low risk of bias in agreement (p > 0.05) among authors, the evaluation of those cross-sectional studies is still limited and requires further longitudinal studies with precise diagnostic parameters. Those parameters for evaluating the relationship between foot posture and malocclusion should encompass both static and dynamic approaches, including those related to mandibular position, tongue posture and function, bad habits, and temporomandibular disorder.

A novel approach for posterior bite collapse in an adult with crossbite anterior using a 3D-printed bite riser

Tue, 03 Sep 2024 00:00:00 +0700

Background: Managing an adult patient presenting with an anterior crossbite in conjunction with posterior bite collapse (PBC) is a difficult challenge. Purpose: The purpose of this case study is to highlight the accuracy that can be attained with the utilization of a three-dimensional (3D) printed bite riser in the correction of PBC accompanied by an anterior crossbite in an adult patient with Class III malocclusion. Case: A 64-year-old male complained of being unable to chew properly. Extraoral examination revealed a concave profile with a protrusive mandible. The patient exhibits a 5 mm anterior crossbite and has missing lower posterior molars, resulting in bilateral PBC. The cephalometric analysis revealed skeletal Class III patterns (SNA: 82.19^o; SNB: 86.34^o; ANB: -4.15°), with protrusion and counterclockwise rotation of the mandible (SN-OP: 3.84^o). Case Management: By utilizing a 3D-printed bite riser in conjunction with temporary anchoring devices (TADs), it is possible to resolve the issue of an anterior crossbite accompanied by PBC. This is achieved by repositioning the elongated posterior segments on both sides of the maxilla to generate vertical space for mandibular tooth rehabilitation, retracting the anterior segment, and narrowing the lower arch. Simultaneously, the crossbite on both sides was corrected, a Class I and ideal overbite and overjet were achieved, the occlusal vertical dimension increased, the occlusal plane angle was corrected (7.51^o), and an acceptable ANB angle (-1.36°) was accomplished. The treatment lasted 18 months and yielded sustained results after a one-year retention period. Conclusion: Integrating 3D printing technology in orthodontic treatment offers numerous options for managing challenging cases such as PBC while also reducing the treatment length. The patient was satisfied with the results achieved.

Unusual odontogenic keratocyst with impacted maxillary central incisor: A diagnosis challenge

Wed, 04 Sep 2024 00:00:00 +0700

Background: Odontogenic keratocyst (OKC) is considered an odontogenic cyst, with the unique clinical characteristics of this entity being local destruction, aggressive behavior, a high recurrence rate, specific histopathologic features, and the tendency for multiple lesions when associated with syndromes. Odontogenic keratocyst accounts for 12–14% of all cysts in the jaws. Purpose: The aim of this case report is to present an unusual odontogenic keratocyst associated with impacted maxillary central incisor, case management of anterior maxilla odontogenic keratocyst involving an adjacent tooth, and its postoperative six-month follow-up. Case: A 13-year-old female patient was referred to the Universitas Airlangga Hospital with a complaint that her upper front teeth had not erupted. The parents revealed that the patient had suffered trauma from falling down the stairs at the age of four, i.e., eight years ago. Case Management: The cyst was enucleated together with the associated permanent upper right central incisor, retained deciduous upper right central incisor, the permanent upper right lateral incisor, and upper right canine. Post surgical treatment, the patient used a partial denture to increase her self-confidence. Conclusion: Enucleation of the cyst with extraction of the permanent teeth should be performed to avoid recurrence of the OKC. Periodic radiographic evaluation is required with long-term follow-up.

Long-standing pleomorphic adenoma in hard palate: A rare case report

Tue, 03 Sep 2024 00:00:00 +0700

Background: Pleomorphic adenoma (PA) is the most common benign tumor of the parotid gland, followed by the submandibular gland, and rarely in the minor salivary glands. However, it has the potential to turn malignant. The minor salivary gland in the hard palate is a rare site for PA. Purpose: This report aims to describe the clinical and histopathology findings and treatment with surgical excision of long-standing PA on the hard palate. Case: 40-year-old woman with an asymptomatic 6 x 4 x 4 cm hard palate tumor mass that had remained untreated for ten years and had no preceding trauma. Case Management: The tumor mass was removed surgically by creating an excision opening of 2–3 mm between the mass margin and the maxillary bone periosteum, extending to the posterior palate. Histopathology findings confirmed the diagnosis of PA in the minor salivary gland and revealed typical characteristics associated with malignant transformation. Observation after one month showed that the surgical wound had healed, and no symptoms of recurrence were visible. Conclusion: PA is a benign salivary gland tumor that has the potential to expand extensively. Appropriate surgical excision can improve the prognosis.

Pediatric facial trauma management: Emergency case in a toddler

Swarantika Aulia Rarasati, Melita Sylvyana, Dian Maifara Putri — Tue, 03 Sep 2024 00:00:00 +0700

Background: Facial soft tissue trauma cases are often encountered in the emergency room. Soft tissue trauma, especially to the face, is rarely life threatening. It varies in shape, size, and depth and can also affect surrounding organs. The treatment of soft tissue trauma can be complicated and may have a significant impact on facial function and, especially, facial aesthetics. Children are easily injured due to their active nature. Soft tissue trauma to the faces of toddlers is challenging even for experienced surgeons; however, wound debridement and suture management under general anesthesia should be considered. Purpose: The aim of this article is to deliver a thorough overview of the evaluation and treatment of soft tissue injuries in children, covering initial assessments, physical examinations, the application of antimicrobial therapies, and preparation for surgical procedures. Case: An 11-month-old girl went to the emergency department of Hasan Sadikin General Hospital, Bandung, with injuries to her left cheek and upper left lip sustained when she fell, and her face hit the edge of a cement pot at home. There was no history of unconsciousness, nausea and vomiting. The injury was diagnosed as vulnus laceratum of the left face and upper lip region. Case management: Emergency management was carried out by triage, Tetagam injection, and early wound debridement and suture under general anesthesia because the patient was uncooperative. Wounds on the face and lips were primary sutured layer by layer, returning the wound edges to their normal anatomical position. Conclusion: The management of facial soft tissue injuries in toddlers requires general anesthesia for adequate and accurate wound debridement and suture, so that functional and aesthetic effects can be satisfactorily obtained.
