Root Resorption Diagnostic: Role of Digital Panoramic Radiography.

INTRODUCTION: Root resorption is a pathological process characterized by loss of dental root substance, caused by bacterial infections, traumatic injuries or chemical irritation. Root resorption might be accidentally observed on digital panoramic radiography. OBJECTIVE: The objective of the study was to identify characteristic radiological aspects for the different types of root resorption that could be observed on digital panoramic radiography, to make an easier diagnostic of root resorption. MATERIAL AND METHOD: The retrospective study used the X-ray base from the Oral Rehabilitation and Dental Prosthetics Clinic of UMF Craiova to identify the most representative images for different types of root resorption. Digital panoramic radiographies were analysed by two investigators, of which the most suggestive images were selected and described. RESULTS: Digital panoramic radiographies and dental charts of 240 patients were analyzed. 113 cases of root resorption were identified. External inflammatory root resorption (EIRR) was present in 27.07% of studied cases, external cervical root resorption (ECRR) was identified in 10.83% of all studied cases, external replacement root resorption (ERRR) was diagnosed in 7.08% of studied cases and internal root resorption (IRR) was the most rare type of root resorption, with only 2.08% from all studied cases. 16 cases were selected to describe the radiologic features of different types of root resorption, featuring the most interesting images of root resorption evident on digital panoramic radiographies. DISCUSSION: Comparative analyses have been made between our results and the results of other specific studies, with both similar and different values. The radiological features which lead to the diagnostic of each type of RR were highlighted, assessing the causes that caused the lesions, as well as the treatment recommendations. CONCLUSIONS: Digital panoramic radiography is a useful tool to identify root resorption, since it has become the most common radiological investigation for diagnostic in dentistry. Description of radiological aspects of different types of root resorption on panoramic digital radiography allows faster diagnosis. Still, the CBCT may be recommended in some cases to confirm the diagnosis.

Statistical Aspects of Partial Edentulism in a Sample of Adults in Craiova, Romania.

The purpose of the study was to analyze the prevalence of different forms of partial edentulism and the description of the various parameters associated with this disease. Materials and Methods. The study was conducted on a total of 204 subjects who presented themselves at the Clinic of Dental Prosthetics and Oral Rehabilitation Clinic of the Faculty of Dentistry Craiova between October 2015 and June 2016. Results. Of the 204 subjects diagnosed with partial edentulism, 51.47% belonged to the age group of 20-29 years, 52.46% were female and 82.84% came from the urban environment. The most frequent cause of the edentulism was dental caries and their complications. The present study has shown that the partial edentulism forms encountered, especially those of the Kennedy III class, had an increased frequency among the young population, especially in the maxillary arch.

Epidemiological Aspects in Lip Tumors in Oltenia Region of Romania During 2012-2016.

PURPOSE: The objective of this study was to review lip tumor diagnosed subjects from Oltenia region, in the past 5 years according to gender, age, home environment, profession, geographic area, smoking habit, associated diseases, tumor location, macroscopic aspect and histological type. MATERIAL AND METHODS: The study was done at the Oral and Maxillo-Facial Clinic of the Emergency Clinical County Hospital of Craiova, and involved the analysis of patient file records, surgical registers, histopathological bulletins, from 2012-2016. RESULTS: Of the 175 subjects included in this study, all of them diagnosed with lip tumor pathology, 109 (62.29%) were men, and 66 (37.71%) were women, all of them with ages between 6 and 92 years, with a mean age of 61 years. Distribution of study participants according to the home residence showed that majority of the subjects lived in rural area. The most frequently localization of lip tumors in study participants was at the lower lip-140 cases (80%), than at the upper lip-35 cases (20%).According to histological characteristics, distribution of the malignant lip tumors was 87.39%-squamous cell carcinoma (SCC), 5.41%-basal cell carcinoma (BCC) and 7.20%-other type of tumors. CONCLUSIONS: The lower lip was the most affected, by lip cancer, and squamous cell carcinoma represents the most frequently histological type of these tumors.

Etiological Aspects of Noncarious Dental Lesions.

PURPOSE: The aim of the present study was to correlate etiological factors with noncarious cervical lesions in a group of patients from Craiova. MATERIAL AND METHODS: The study was conducted between November 2015 and May 2016 on 50 patients, aged 18-56 years, who addressed to the Oral Rehabilitation Clinic, from the University of Medicine and Pharmacy of Craiova. Patients were divided into two groups: the study group consists of patients who had noncarious cervical dental lesions (NCCLs) and the control group with patients who did not have noncarious cervical lesions. Each patient underwent a clinical examination and completed a questionnaire, referring to eating habits, oral hygiene, vicious habits and personal impressions about the appearance and functionality of his teeth, highlighting the factors involved in the noncarious dental lesions etiology. RESULTS: The study group consisted of 64% women and 36% men. Noncarious cervical lesions were higher in men (72.22%) compared to women (56.25%). Regarding on the tooth brushing method, it has been noted that 34% of patients used a vertical tooth brushing method, 52% were using a circular brushing method, while 14% were practicing a horizontal tooth brushing method. Cervical sensitivity has been detected in 48% of the patients, against 52% who showed no sensitivity. 62% of the participants did not have bruxism, while nighttime/daytime bruxism was found in 38% of the patients. CONCLUSIONS: There are several etiological factors correlated with noncarious cervical lesions, among which are: tooth brushing method, bruxism, eating behaviors.

Risk of Dental Caries for Children Aged 4 to 6 in Craiova.

Dental caries represent a chronic disease of high prevalence for the human body and is produced by the interaction of a number of predisposing factors throughout the time. Specialized studies in recent years have made some progress with regard of complex interacting factors in the process of developing dental caries in children, but due to the plurifactorial nature of the disease it seems that there is still much to be studied regarding the start, progress and prevention of tooth decay.The aim of the study was to determine the risk of tooth decay in children aged 4 to 6 years in Craiova and the relationship of the main etiopathogenic cariogenic factors. MATERIAL AND METHODS: The study included a total of 101 children of both sexes, aged 4-6 years, from two kindergartens in Craiova. They filled out questionnaires about food and oral hygiene habits and after that the study protocol included visual clinical examination in according to WHO methodology; determination of dmft index with the analysis of dt, mt and ft component The results were recorded in personal files and were analyzed statistically. RESULTS: The results of our study were consistent with data from the literature of recent years. So, the highest value of the dmft index (2.52) was at the age group of 6. CONCLUSIONS: The most significant contribution to the values of carious experience is the number of teeth affected by caries at the expense of obturated ones.

Prosthetic Treatment Possibilities for Extended Partially Edentulous and Completely Edentulous Patients, Depending on the Clinico-Morphological Characteristics of the Oral Mucosal Substrate.

The number of partially and completely edentulous patients requiring removable prosthetic treatment has increased constantly and denture wearers often have an associated oral status pathology. The purpose of this article is to present removable prosthetic treatment options that we chose for the extended partially edentulous and completely edentulous patients who required prosthetic rehabilitation treatment. We conducted this study on 52 extended partially edentulous and completely edentulous patients. We recorded in the examination chart the characteristics of the mucosal membrane covering the denture supporting structure and the peripheral structures and we performed a statistical analysis using Microsoft Excel. The prosthetic treatment phases were individualized according to morphological characteristics of the oral mucosal substrate.
