Lateral root perforations are unfortunate procedures during endodontic treatment and often lead to tooth extraction. Conditioning factors such as time, size, location, inappropriate disinfection and sealing, are indispensable to achieve acceptable long-term outcomes. Calcium silicate cements are bioactive materials used for perforation repair. They can be set in moist environments such as blood, saliva and dentinal fluid making them a reliable material for clinical applications. This case report describes the treatment and repair after a 16-month follow-up of a lateral root perforation of the maxillary lateral incisor.

Prosthetic rehabilitation of a missing tooth with tilted abutments is yet an enigmatic and less unconventionally sought-after treatment strategy. Many methods have been previously reviewed over the years. This clinical report aims to integrate the principles of the segmented fixed dental prosthesis into a digital workflow. It elucidates the rehabilitation using a split-pontic design that mitigates the issue of developing a common path of insertion without much compromise to the tooth preparation to derive parallel prepared walls. This prosthetic design rather incorporates a common path of insertion into the pontic in the form of a key-keyway non-rigid connector design.

Double teeth refer to two teeth that are totally or partially joined by dentin and maybe their pulps. These developmental anomalies may be the result of either gemination or fusion. This is a case of a 15-year-old Indo-Trinidadian male who presented with the fusion of a mandibular third molar with a distomolar as an incidental finding. The patient had his general dental care provided by a paediatric dentist and was referred to an oral and maxillofacial radiologist, orthodontist, and oral surgeon for consultation. A Cone-beam CT was taken to supplement the plain film periapical and orthopantomogram radiographs. It showed the three-dimensional orientation of the double molar and the extent of joining. This is the first case of fusion of a mandibular third molar to a distomolar being reported in the Caribbean.

Background: Diabetes increases periodontal disease risk and its complications, which are worsened with age or faulty restorations. Aim: Evaluate periodontal health among patients with diabetes treated with different dental restorations. Materials and Methods: This comparative cross-sectional study was conducted at the faculty of dentistry, Najran University, KSA, from March 2018 to February 2020. It included 260 diabetics, treated with different dental restorations, divided into four groups, each comprising 65 patients aged 45 - 60 years: Group 1 (G1), no restorations (control group); Group 2 (G2), Class II amalgam restorations; Group 3 (G3), Class II composite resin restorations; and Group 4 (G4), three-unit posterior metal ceramic prostheses. The Ages of all restorations ranged from 8 to 10 years. All groups were assessed for the Plaque Index (PI) and Gingival Index (GI), Overhangs Rate (OR), Alveolar Bone Loss (ABL) (the latter two using panoramic X-ray). HbA1c and duration of participants were also assessed and compared. Results: The mean HbA1c results of the groups ranged from 8.1% to 9.5%, and their mean diabetes durations ranged from 7.2 to 12 years. All the groups showed worse periodontal scores, ranging from 2.45 - 2.95 for PI and 2.25 - 2.8 for GI. G2 had higher scores than G1 and G3 (p p p p = 0.987). The highest value was observed in G4, which was significantly higher than other groups (p < 0.001). Conclusion: The worse periodontal parameters among subjects treated with either three-unit metal ceramic or Class II amalgam restorations indicated severe periodontal destruction. Untreated subjects and subjects treated with Class II composite resin had relatively better periodontal status.
背景：糖尿病会增加牙周病及其并发症的风险，而这些风险会随着年龄的增长或修复不良而恶化。目的：评价不同牙修复体治疗的糖尿病患者的牙周健康状况。材料和方法：这项横断面比较研究于2018年3月至2020年2月在KSA纳格兰大学牙科学院进行。研究包括260名糖尿病患者，他们接受了不同的牙齿修复治疗，分为四组，每组65名年龄在45-60岁之间的患者：第一组（G1），不进行修复（对照组）；第2组（G2），II级汞合金修复体；第3组（G3），Ⅱ类复合树脂修复体；第4组（G4），三个单元的后部金属陶瓷假体。所有修复体的年龄从8岁到10岁不等。评估所有组的牙菌斑指数（PI）和牙龈指数（GI）、上翘率（OR）、牙槽骨丢失（ABL）（后两组使用全景X射线）。还对参与者的HbA1c和持续时间进行了评估和比较。结果：两组的平均HbA1c结果在8.1%-9.5%之间，平均糖尿病持续时间在7.2-12年之间。所有组的牙周评分均较差，PI评分在2.45-2.95之间，GI评分在2.25-2.8之间。G2的评分高于G1和G3（p p p=0.987）。G4的评分最高，结论：三元金属陶瓷或II类汞合金修复体的牙周参数较差，表明牙周破坏严重。未治疗的受试者和用II类复合树脂治疗的受检者的牙周状况相对较好。

In this manuscript, the authors have studied the Disc Displacement (DD) status of patients with acute Closed Lock (CL) to determine differences between DD with Reduction (DDwR) and DD without Reduction (DDwoR). Among the acute CL patients who visited our hospital within 2 weeks of the onset of CL, we studied 10 patients whose CL was released (DDwR) and 13 patients whose CL was not released (DDwoR). The DDwoR group was significantly older than the DDwR group. Although the mouth opening distance was significantly greater in the DDwoR group than in the DDwR group, the two groups were identical in the duration of CL. Sagittal MRI images showed no significant differences between the two groups in disc length and disc thickness (anterior band, intermediate zone, and posterior band). Multisection sagittal and coronal images identified lateral DD in 7 of the 10 patients in the DDwR group, although no specific direction of the DD was observed in the DDwoR group. Furthermore, deformation of the medial disc was common in the DDwoR group but uncommon in the DDwR group.

Introduction: The goal of this study was to utilize physical characteristics instead of placing subjects in arbitrary diagnostic categories to test for associations with genetic variants. Methods: Forty-four single nucleotide polymorphisms were tested for association with specific cephalometric measurements in thirty-nine University of Pittsburgh Dental Registry and DNA Repository orthodontic subjects. Cephalometric measurements included an evaluation of FMA, a Wits appraisal, and a Steiner’s ANB analysis. Genetic markers were genotyped using polymerase chain reaction and Taqman chemistry. Chi-square and Fischer’s exact tests (α = 0.05) were used in investigation of overrepresentation of marker alleles. Samples were divided into groups based upon having an FMA, Wits, or ANB measurement above or below the mean of the cohort studied. Secondary analysis was done for sex and ethnicity to determine their effect on FMA, Wits, or ANB. Results: An association between FMA measurements was discovered in the following genes: ACTN3, CASP4, ESR1, FGF13, KRT7, and PITX2. An association between Wits measurements was discovered in the following genes: ACTN2, BTBD11, CASP4, FGF3, and FGF10. No associations were found with ANB. Conclusions: Genetic markers in several genes at different loci may contribute to craniofacial deformities in humans. This approach of using physical measurements may be an advantage to placing patients in arbitrary diagnostic categories.

Purpose: The purpose of this study was to identify optimal post and core materials for central incisors without ferrules using three-dimensional finite element analysis and three-point bending tests. Methods: Stress analyses were performed with six models: cast metal post and core (MP), composite resin core alone, straight fiber-reinforced post-composite resin core (FSR), tapered fiber-reinforced post-composite resin core, straight titanium post-composite resin core (TSR), and tapered titanium post-composite resin core (TTR). A 100-N load was applied to the lingual surface at a 45° angle to the long axis of the tooth. Maximum von Mises stress distributions were calculated with finite element analysis software. Five samples each of composite resin, straight fiber-reinforced post, straight titanium post, straight fiber-reinforced post and composite resin, and straight titanium post and composite resin were subjected to three-point bending tests, followed by analysis of variance and Tukey’s multiple comparison test. Results: Stress distribution was optimal on TTR. Maximum von Mises stress on the cervical side of the post was greatest in TSR (693 MPa) and TTR (556 MPa). Maximum stress on the apical side of the post was greatest in MP (110 MPa). Maximum stress in surrounding dentin was lowest in MP (203 MPa) and TTR (250 MPa). Gap distance was smallest in MP (0.09 mm) and largest in FSR (0.26 mm). Mean maximum three-point bending force was lowest in composite resin (26.9 N/mm) and highest in titanium post and composite resin (97.1 N/mm). Titanium post bending strength was consistently greater than that of the fiber-reinforced post (p < 0.01). Conclusion: These results revealed optimal stress distribution and high bending strength with the tapered titanium post and resin combination, suggesting that this combination can most effectively prevent root or post fracture in an anterior tooth without a ferrule.

Objective: Pain tends to be the chief complaint in patients suffering temporomandibular disorders (TMD). Previous studies on pain and psychosocial factors have reported on the relationship between presence of pain and mental disorders. To date, however, few studies have addressed the relationship between intensity of pain and psychosocial factors. In this study, we investigated the relationship between intensity of pain and age, gender, palpation scores (PPS), tendencies toward depression, anxiety, and somatization, and oral parafunctional habits. Methods: This screening survey encompassed 104 patients (70 women and 34 men; mean age of 46.1 ± 19.3) who visited our clinic. We gathered the following data: age; gender; PPS included in Axis I diagnosis; and characteristic pain intensity (CPI), depression, anxiety, somatization, and oral parafunctional habits (assessed by the Oral Behavior Checklist) included in Axis II diagnosis. Based on the results of CPI, we divided patients into two groups: those experiencing low pain intensity (LP group) and those experiencing high pain intensity (HP group). The statistically significant level was set to below 5%. IBM SPSS Statistics V25 was used to perform all statistical analyses. Results: We observed no gender differences between LP and HP groups. The HP group included significantly more patients with higher scores for depression, anxiety, somatization, and oral parafunctional habits than the LP group. While no gender differences were observed in CPI, depression, anxiety, somatization, and oral parafunctional habits were significantly more common in women than in men. We observed no differences in age or PPS between the LP and HP groups. However, scores for depression, anxiety, somatization, and oral parafunctional habits were significantly higher in the HP group than in the LP group. We performed multiple regression analysis using the CPI score as the dependent variable and scores for depression, anxiety, somatization, and oral parafunctional habits as independent variables in both the LP and the HP groups. We identified no significant predictors for the LP group, but extracted depression as a significant predictor in the HP group. On evaluating the correlation of PPS with depression, anxiety, somatization, and oral parafunctional habits in both the LP and the HP groups, we found no correlation between the PPS and the seven-item generalized anxiety disorder (GAD-7) scale in the LP group but identified a significant correlation between the PPS and GAD-7 scores in the HP group. Moreover, the correlation coefficient between the patient health questionnaire (PHQ)-9 and GAD-7 scores was higher in the HP group than in the LP group. Conclusion: In those reporting more intense pain, we found a stronger correlation among psychological factors in patients diagnosed with TMD. Greater tendency toward depression was directly associated with pain intensity. The results point to the need to consider differences in psychoso

Objective: The present work aimed to identify the most common edentulousness and prosthesis type (prosthetic treatment), to improve the management in oral prosthetic rehabilitation in DR Congo. Material and Methods: It was a documentary, longitudinal, and retrospective study of the medical records of edentulous patients admitted to the prosthetic service of the Dental Department/Kinshasa University from January 1983 to December 2020. Age, sex, cause of teeth loss, and prosthetic treatment (partial removable prosthesis, complete removable prosthesis) were evaluated. The Chare square test was performed to compare significant differences between the variables and the P-value < 0.05 was set as significant. Results: One thousand six hundred and ninety patients in that 901 were men (47 ± 16 years) and 789 women (42 ± 15 years) had undergone prosthetic treatment. One thousand eight hundred and forty-four edentulous teeth were viewed according to the Kennedy classification. Kennedy class 1 was the most predominant (61.4%) followed by Kennedy class 3 (24.8%). Two thousand one hundred and ninety-one prostheses were performed. The removable partial prosthesis with plate (acrylic resin) was the most performed (78.8%; n = 1727) and followed by the joint (17.4%; n = 384). Dental caries (52.6%) and periodontitis (36.4%) were the main causes of these edentulous teeth. Conclusion: The present study showed that edentulism is becoming a concern for the implementation of a real oral health policy.

Chronic periodontitis is a disease of public health concern due to its high prevalence globally, especially in the elderly. The aim of this study was to determine the impact of non-surgical periodontal therapy on salivary levels of TIMP-1 among patients with chronic periodontitis in Nigeria. In this experimental study, unstimulated whole saliva (2 mL) was collected from participants in the experimental and control groups, coded (SP1-40 and SH1-40) respectively and assays for salivary TIMP-1as well as clinical measurements such as plaque (PI), probing depths (PD), and CAL were recorded before and 4 weeks after periodontal treatment. Assay was done using Quantikine human TIMP-1 ELISA kit. Data were presented using frequency tables, means and standard deviation. Paired-T Test assessed association between salivary TIMP-1 before and after treatment. Pearson correlation coefficient was used to correlate salivary TIMP-1 levels with clinical parameters of periodontal disease and levels of statistical significance were set at p < 0.05. A total of 80 respondents participated in the study of which 43.80% were females. Age range was 18 - 60 years with a mean of 35.8 ± 12.46 years. Salivary TIMP-1 levels were lower in the case group (13.58 ± 6.53 ng/mL) than the control (15.27 ± 6.10 ng/mL) at baseline but this was not statistically significant (p = 0.13). There was a statistically significant increase in the salivary levels of TIMP-1 in the case group after phase-one periodontal therapy from 13.58 ± 6.53 ng/mL to 17.24 ± 8.44 ng/mL (p = 0.001). Negative correlations were observed between TIMP-1 and clinical parameters of periodontitis. This was not statistically significant. Therefore, TIMP-1 may not be an ideal biomarker for periodontal diagnosis but may be useful in treatment monitoring of the disease.
