Masticatory performance has been studied extensively in the past few decades. Age, gender, the number of teeth in occlusion, occlusal contact area, salivary flow, and neurophysiological deficits influence the masticatory process. The replacement of missing teeth with dental prostheses, whether fixed or removable, is often used to achieve an acceptable level of masticatory performance. Objective: The present study aimed to analyze the association between masticatory performance and age, gender, and oral health status based on the decayed, missing, and filled teeth (DMF-T) score, denture use, and denture condition in an adult population. Methods: This study included a total of 152 individuals (60 males and 92 females) aged 17 years or older (mean ± standard deviation: 33.4 ± 13.1 years). Masticatory performance was evaluated using color-changeable chewing gum. The chi-squared test was used to assess the association between masticatory performance and age, gender, DMF-T score, dental prosthesis use, and prosthesis condition. Results: Age (p=0.001), missing teeth (p=0.001), and prosthesis use (p=0.011) had significant relationships with masticatory performance. However, the correlations between masticatory performance and gender, tooth decay, fillings, and prosthesis condition were not statistically significant (p> 0.05). Conclusion: Age, missing teeth, and prostheses are strongly associated with masticatory performance.

Multiple ulcerations are rarely caused by a traumatic event, but seizures can induce repeated injury to the oral mucosa. A patient with a seizure history possesses a challenge in their dental management. Objective: In order to describe a case of multiple oral ulceration in a post-seizure patient with undiagnosed arteriovenous malformation (AVM) in the left parietal lobe and provide short guidelines for dentists in managing patient with a seizure history. Case report: A 23-years old female had multiple oral ulceration in the right and left buccal mucosa and her tongue. She reported having a seizure attack six days before. The patient never had a history of seizures or recurrent oral ulceration. During the seizure, improper placement of the spoon caused further damage to her oral mucosa. The trigger of her seizure is unknown. Based on the neurological consultation, she had an AVM on the left temporal lobe. In order to relieve pain, mouthwash containing aloe vera, sodium hyaluronate, glycyrhettinic acid, and polyvinylpyrrolidone (PVP) was prescribed. Conclusion: Dentists should be aware that oral mucosal injury can be related to a seizure disorder. A proper history and examination are essential to make an appropriate diagnosis. A safe dental treatment in seizure patients can be delivered accordingly

The prevalence of complete edentulism varies from country to country and from one region to another. Previous studies have reported the high prevalence of significant radiographic findings in edentulous patients. Objectives: This study aimed to determine the prevalence of complete edentulism retrospectively and to evaluate the frequency and location of significant radiographic findings on panoramic radiographs in edentulous jaws of dental patients in northeastern Turkey. Methods: The digital panoramic images of all ≥35 year-old patients admitted to our faculty from January 2014 to August 2015 were evaluated. The prevalence of complete edentulism was determined among 8314 panoramic images retrospectively. Radiographic findings identified as impacted teeth, retained roots, radiopaque, and radiolucent areas detected in panoramic radiographs of completely edentulous patients (CEP) were recorded. The obtained data were analyzed with descriptive statistics and cross-tabs. Chi-square test was employed to evaluate the statistical significance of the results at 0.05 levels. Results: A total of 8314 panoramic images were examined, and 508 (6.11%) CEP were defined. The prevalence of edentulism was higher (24.85%) among the patients older than 64 years old. A total of 206 radiographic findings were detected on panoramic images of CEP. The prevalence values of retained roots, impacted teeth, radiopacities, and radiolucencies were 18.9%, 7.09%, 2.76%, and 1.57%, respectively. Conclusions: Given the high frequency of significant radiographic findings, the radiographic examination of CEP should be performed with consideration of the cumulative effects of radiation.

The orthopantomogram (OPG) is a common dental screening radiograph that has multiple implications. However, lateral cephalogram is the investigation of choice for the assessment of vertical facial pattern. Objective: The aim of the current study was to investigate the validity of an OPG parameter i.e. panoramic gonial angle (PGoA) for the assessment of the vertical facial pattern. Methods: A cross-sectional study was conducted on the pretreatment OPG and lateral cephalograms of 200 orthodontic patients aged 15-40 years. The PGoA was measured on both sides and an average was used for statistical analysis. The Pearson’s correlations of PGoA were measured with cephalometric gonial angle (CGoA), SN-GoGn, MMA, FMA, LAFH/TAFH% and PFH/TAFH%. The diagnostic test statistics were applied for PGoA against gold standard “definitive diagnosis (DD)” derived from SN GoGn and FMA. A p-value of <0.05 was taken as statistically significant. Results: The mean CGoA was 121.18o ± 5.16o which was significantly different (p <0.001) from the mean PGoA 117.14o ± 4.43o. PGoA was significantly correlated with SN-GoGn, MMA, FMA and CGoA. A standard of PGoA 116o±3o was used to classify subjects into low angle, normal angle and high angle groups. The validity of PGoA with DD showed a sensitivity of 90.32%, 82.72% and 77.78%; and specificity of 95.37%, 84.48% and 91.96% for low angle, normal angle and high angle cases, respectively. Conclusion: The current study identifies PGoA as a valid tool for the assessment of vertical facial pattern of orthodontic patients with its normal value 116o±3o in our sample.

Eliminating microorganisms in the root canal system is important for the success of regenerative endodontics. Objective: This study evaluated the effects of different antibiotic pastes used for regenerative endodontic procedures on dentin microhardness and the push-out bond strength of mineral trioxide aggregate (MTA) to root canal dentin. Methods: Sixty-four maxillary central incisors were instrumented and randomly divided into the following four groups (n = 16) for medicament treatment: triple antibiotic paste, amoxicillin+clavulanic acid, cefaclor, and control (no dressing). After 21 days, two root segments were obtained by sectioning the roots horizontally for push-out and microhardness evaluations. MTA was placed into the root canal of the sectioned segment for the push-out test. In the microhardness evaluation, three indentations were made at 500 and 1,000 μm from the canal lumen. The arithmetic mean was then calculated for each distance. ANOVA with post hoc Scheffe test and t test were used for the statistical analyses. The significance level was set at p < 0.05. Results: No significant difference was found between the groups in terms of push-out bond strength (p > 0.05). Cefaclor and amoxicillin+clavulanic acid reduced the microhardness values of the dentin at 500 μm (p < 0.05) while cefaclor had the lowest value at 1,000 μm (p < 0.05). Conclusion: Cefaclor reduced the microhardness value more than the other medicaments did at a depth of 1,000 μm. The pastes provided similar adhesion of MTA.

Objective: This study aimed to examine the cone beam computed tomography (CBCT) images of impacted maxillary canines and mesiodentes. Methods: This retrospective radiographic study was performed on 177 patients with 200 impacted maxillary canines and 12 mesiodentes. Using CBCT images, the unilateral/bilateral occurrence, presence of root dilaceration, mesio-distal and buccopalatal location, impaction condition, contact region of adjacent teeth, presence and degree of root resorption of adjacent teeth, dental follicle width, closest distance to the nasal cavity, nasopalatinal canal, and maxillary sinus were assessed. For mesiodentes, the types, follicle width, direction, and relationship with anatomical structures were evaluated. Results: No statistical relationship was found between (buccopalatal and mesio-distal) position of canine and root resorption of adjacent teeth (p = 0.171). A negative correlation was observed between age and follicle width (r = −0.145, p = 0.048). No mesiodens with enlarged follicle and root resorption of adjacent teeth was found. Conclusion: Given the negative correlation between age and follicle width, older patients with impacted teeth can be followed up by two-dimensional radiographs unless periradicular radiolucencies are absent. Otherwise, CBCT evaluation is required for early detection of pathologies and prevention of possible surgical complications.

Many root canal preparation techniques and instruments produce apically extruded materials to a certain extent depending on the preparation system adopted. The extrusion of debris from the apical foramen during chemomechanical preparation may cause postoperative pain and failure of endodontic treatment. Objective: This study evaluates the differences in the apical extrusion of debris and calcium hydroxide (CH) during endodontic instrumentation by using Reciproc Blue (RB), WaveOne Gold (WOG), and F6 Skytaper (F6). Methods: Six experimental study groups (n = 13) were established. The root canal procedures for all groups were prepared with different methods: Group I: One Shape (OS) instrumentation, CH filling for 21 days, removal of CH using RB; Group II: OS instrumentation, CH filling for 21 days, removal of CH using WOG; Group III: OS, CaOH filling for 21 days, removal of CH using F6; Group IV: root canal instrumentation using RB; Group V: root canal instrumentation using WOG; Group VI: root canal instrumentation using F6. Apically extruded debris was collected into preweighed Eppendorf tubes by using the Myers and Montgomery method. Data were statistically analyzed with one-way ANOVA and Kruskal–Wallis tests. Results: All the tested instruments caused the extrusion of debris and irrigant from the apical foramen. The difference among the six groups was not statistically significant (p > 0.05). Conclusions: The tested instruments caused similar apical extrusions of debris and irrigant during CH removal or instrumentation procedures.

Objective: Stainless steel crowns (SSCs) are preformed metal crowns used to restore severely decayed primary teeth. The aim of this study is to evaluate the effects of pH changes and SSC margin trimming on nickel release in artificial saliva solution. Methods: A total of 90 SSCs were divided into three groups and placed in 35 ml of artificial saliva of pH 6.8, 5, and 3.5. Another group consisting 30 SSCs with trimmed margins was placed in saliva of pH 6.8. All SSCs were incubated at 37°C. The concentration of released nickel was assessed on days 1, 7, 14, 21, and 28 by atomic absorption spectrophotometry. Results: The highest concentrations of nickel were released on the first day in all groups. Nickel release increased with decreasing pH, and the differences observed were statistically significant on days 1, 7, 14, and 28. SSC trimming caused a significant increase in nickel release on all days except day 21. Conclusion: The concentration of nickel increased in saliva of low pH. The highest levels of nickel were released with SSC margin trimming because of the loss of integrity of the margins.
目的：不锈钢牙冠（SSCs）是一种预成形的金属牙冠，用于修复严重龋坏的乳牙。本研究的目的是评估pH变化和SSC切边对人工唾液溶液中镍释放的影响。方法：将90个SSCs分为三组，分别放入35 ml pH为6.8、5和3.5的人工唾液中。将另一组由30个具有修剪边缘的SSC组成的组置于pH 6.8的唾液中。所有SSC均在37°C下孵育。在第1、7、14、21和28天通过原子吸收分光光度法评估释放的镍的浓度。结果：在所有组中，第一天的镍释放浓度最高。镍的释放随着pH值的降低而增加，在第1、7、14和28天观察到的差异具有统计学意义。SSC修整导致除第21天外的所有日子镍释放显著增加。结论：低pH唾液中镍含量增加，SSC切缘时镍含量最高，因为切缘的完整性丧失。

The highest levels of nickel were released with SSC margin trimming because of the loss of integrity of the margins.","PeriodicalId":53873,"journal":{"name":"Journal of Dentistry Indonesia","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46132796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Perforation is one of iatrogenic factors responsible for endodontic failure. Root canal perforation can occur at the cervical, mid-root, or apical levels. Non-surgical (conservative) perforation repair offers less tissue destruction and easy isolation during treatment. Objective: To explain the management of apical third root perforation using the conservative technique. Case Report: This case report describes a 29-year-old patient who came for management of right maxillary lateral incisor with apical third root perforation on the labial aspect. The location of apical third root perforation was evaluated using cone beam computed tomography (CBCT). Root perforation was sealed using mineral trioxide aggregate (MTA). MTA was applied in conservative technique with hand filling. MTA was dispensed into the original canal while maintaining the patency of the perforated canal, followed by dispensed of MTA into the perforated canal. Conclusion: Root perforation should be identified as soon as possible and could be easily examined using CBCT. Non-surgical root perforation treatment is recommended in intact periodontal attachment and in absence of inherent complication. Repairing the root perforation promote the proper healing of the periapical tissue and increase the success rate of retreatment.
