Radiographical Measurements of Overeruption in Unopposed Posterior Teeth Among Selected Population of Saudi Arabia

The suspended replacement of extracted teeth may disrupt the structural integrity of the whole dental arch, particularly in posterior maxillary or mandibular tooth/teeth. This phenomenon often has consequences of masticatory deficiency and temporomandibular joint disorders. This work aims to assess and measure the overeruption of posterior teeth from panoramic radiographs (OPGs) and its relation to gender, age, tooth type, arch, sides, and cause of tooth loss. A total of 100 OPGs were included in this in vitro study. The level of posterior overeruption was measured in mm using the panoramic digital radiograph machine and its software systems. Other variables such as gender, tooth/teeth involved, arches, and side were considered. All parameter values were inputted to a software program and assessed. P value < 0.05 was considered as statistically significant. Males accounted for 63% of the OPGs. Age groups 18–30 and 31–45 years had the highest frequency and percentage (34%). Approximately 74% of the patients got their tooth/teeth extracted 4–6 years ago. The 0.7–1.2 mm overeruption subgroup had the highest proportion of 41%. The rate of overeruption in mandibular molars was 36%, which was the highest among the subgroups. Males had higher percentage than females in ≥60 and 31–45 age groups (84.65% and 76.5%, respectively), 4–6 years post-extraction time (85.7%), with significant differences, also, mandibular molars (85.0%) and mandibular arches (74.3%) were the higher among males. The highest level of overeruption was 0.7–1.2 mm, and mandibular molars were the most affected type. Significant differences between genders were detected in age groups, years after tooth loss, and arch side but not in cause of tooth loss, supra-erupted tooth type, and arch type parameters.

Diagnostic Performance of Digital Radiograph and Low-Dose Computed Tomography for the Diagnosis of Fishbone Retention in the Oropharynx

Introduction Fishbone foreign body retention is one of the most common problem with various clinical manifestations from asymptomatic, abscess formation, and perforation to mediastinitis with subsequence morbidity and mortality. Accurately identifying the location of the fishbone leads to precise removal, which, in turn, prevents serious consequences. Digital radiographs have been widely used for diagnosis, but many studies show poor sensitivity. Object The present study was designed to compare the diagnostic performances of digital radiograph and low-dose computed tomography (CT) for fishbone retention and to demonstrate the radiation dose of the two modalities. Methods We collected 2 pieces of fishbone from each of the 15 species commonly eaten in Southeast Asia. We embedded each fishbone in a fresh pig's neck, then subjected the pig's neck to lateral soft tissue neck digital radiograph. The locations to embed included tonsil, base of tongue, and upper esophagus. Then, we subjected the same specimen to a CT scan. Two experienced radiologists interpreted each image. Results Visibility in the digital radiograph group was 13%, and in CT images group, it was 87% regardless of the locations. The average radiation dose from digital radiographs was 0.4 mGy (radiation dose field), while from CT images it was 8.6 mGy (CT dose index). Conclusion Most of the common fishbones in Southeast Asia could not be visualized by digital radiograph when embedded in the neck. Computed tomography scans demonstrated better diagnostic performance of fishbone retention compared to digital radiographs, regardless of the embedded location.

Successful Outcome After Intralesional Curettage for Spindle Cell Hemangioma of Fibula in an Infant: A Case Report

Spindle cell hemangioma (SCH), a non-neoplastic reactive vascular lesion, rarely locates in bones. We herein report a successful case of intralesional curettage for an infant with SCH of fibula. An 11-month-old boy was admitted to our center with a painless mass in the right proximal calf. Preoperative digital radiograph demonstrated a massive vascular lesion with an irregular bone destruction of proximal fibula. The lesion was removed via the intralesional curettage approach and pathologically diagnosed as SCH. The patient gained bone structure recovery of right proximal fibula. Two years after the surgery, he experienced no local recurrence. For the management of SCH of fibula with partial bone destruction, we suggest early-stage intralesional curettage as its safety and effectiveness.

A Comparison of Cone Beam Computed Tomography and Periapical Digital Radiography for Evaluation of Root Canal Preparation

The aim of the present study is to compare cone beam computed tomography and periapical digital radiography for the evaluation of root canal preparation. Nine extracted human molars were used in this study. Following access cavity preparation, mesio-buccal roots of maxillary and mesial roots of mandibular molars were prepared and the remaining roots were cut off. Three amalgam cavities were prepared on the coronal part of the teeth and were filled with amalgam to be used as landmarks. Specimens were scanned using cone-beam computed tomography and periapical digital radiograph images were obtained before and after root canal preparation. WaveOne Gold Primary was used for root canal preparation to full working length. Specimens were then scanned using CBCT and a periapical radiograph for the after-instrumentation images. The transportation and centering ratio were measured and calculated on the CBCT and periapical radiographic images. The Bland–Altman method was used for detecting the bias in the evaluation of agreement between the two methods’ measurements. There was agreement between the two methods’ measurements using CBCT scans and periapical digital radiographic images in the evaluation of transportation and centering ratio parameters. The two methods could be used interchangeably in measurements of transportation and calculating the centering ratio.

Estimasi usia prajurit TNI AL berdasarkan Tooth Coronal Index pada digital radiograf panoramik

Objectives: The purpose was to determine the estimated chronological age difference between Indonesian Navy soldiers (TNI-AL) and dental age based on the Tooth Coronal Index on panoramic digital radiographs, which are used as antemortem data for the purposes of identifying Indonesian Navy soldiers if they have an accident while on duty or on the battlefield where only tooth remains. Material and Methods: The method used was a cross-sectional observational survey with the sampling technique using purposive sampling. This study used 86 digital panoramic radiographs of Indonesian Navy soldiers who were assigned abroad from 2015-2017 at the Dental Radiology Installation of Ladokgi TNI AL R.E. Martadinata. The teeth measured were mandibular first molars with the Tooth Coronal Index (TCI) method, which is a method of estimating age based on secondary dentin deposition and tooth pulp size on dental radiographs. Results: The results of the chronological age difference with the dental age of Indonesian Navy soldiers using the Tooth Coronal Index (TCI) method on a panoramic digital radiograph performed on mandibular first molars were an average of 6.3 years. Conclusion: The dental age of Navy soldier is higher than chronological age.
