In the study the cephalometric method was used to determine the position of the artificial central upper and lower incisors of edentulous patients class I, and natural central upper and lower incisors of dentulous individuals class I. Cephalometric radiographs of edentulous patients were made with a precisely set position of frontal teeth and marked central incisors. The control group consisted of 30 lateral cephalometric radiographs of dentulous persons class I. Certain of Schwartz and Steiner cephalometric radiograph analysis were used for precise sagittal positioning of upper and lower central incisors. To set precisely the position of these teeth in a sagittal position, the inclination of their axle was analyzed on each cephalometric radiograph, as well as the position of their vestibular surfaces related to the specific craniofacial elements. Statistically significant differences of the value of the angle of inclination of artificial upper and lower incisors of edentulous patients class I, and the angle of inclination of natural upper and lower incisors of dentulous persons, class I, were determined.

One of the existing methods for analysis of the vertical dimension of occlusion or occlusal face height is the cephalometric analysis of the distance from nasion to menton (N-Me). The vertical dimension of occlusion was measured in 30 lateral cephalometric radiographs of edentulous patients (experimental group), with models of complete dentures after clinical methods of determining the vertical and horizontal intermaxillary relation and 30 lateral cephalometric radiographs of participants with natural teeth (control group). The aims of the present study were: to analyse the vertical dimension of occlusion in participants with natural teeth skeletal class I, to cephalometrically evaluate the reconstructing vertical dimension of occlusion of edentulous patients skeletal class I , to compare examined variables between individuals with natural teeth and edentulous patients. The results indicated a remarkable correlation in the vertical dimension of occlusion established initially for the edentulous patients when compared with the measurements made for dentulous patients. The results showed the vertical dimension of occlusion span a range between 106,7 - 138 mm (X _ =122,24) in subjects with natural teeth. In edentulous patients the values of vertical dimension of occlusion span ranged between 109,8 - 141,6 mm (X _ =122,46). The vertical dimension of occlusion in male participans was increased in the group of persons with natural teeth as well as in edentulous patients. The results of t-test proved that there were no statistically significant differences in examined variables between persons with natural teeth and edentulous patients (p>0,01).

INTRODUCTION: Anterior open bite (AOB) malocclusion presents as lack of vertical overlap of anterior teeth. It is viewed to be unaesthetic and may affect speech and mastication It develops due to the interaction of hereditary and environmental etiological factors and these usually affect the vertical growth of the face. This study describes the vertical changes of South African black people presenting with AOB. AIMS AND OBJECTIVES: The aim was to determine skeletal morphological features of patients with AOB malocclusion. DESIGN: The design was a retrospective, cross-sectional study. MATERIALS: Archived pre-treatment lateral cephalographs of 181 patients who consulted between 2007 and 2014 were divided into four groups: control group of 62 patients with skeletal Class I pattern without AOB; test groups of patients with AOB (119) divided into 35 Class I, 43 Class II, and 41 Class III malocclusions. Records of each group were divided according to gender. Descriptive statistics, the Pearson correlation coefficient, t-test and. Wilcoxon test were employed to analyze the data, and p values of <0.05 were considered statistically significant. RESULTS AND CONCLUSIONS: Patients with AOB had a larger vertical facial pattern in all classes of malocclusion. Males presented with larger Sn-GoGn angles than females. The PFH/AFH ratio was lower across all classes of malocclusion compared to the control group.

INTRODUCTION: A female patient aged 12 years and 2 months had molars and canines in Class II relationship, severe overjet (12 mm), deep overbite (100%), excessive retroclination and extrusion of the lower incisors, upper incisor proclination, with mild midline diastema. Both dental arches appeared constricted and a lower arch discrepancy of less than -6.5 mm. Facially, she had a significant upper incisors display at rest, interposition and eversion of the lower lip, acute nasolabial angle and convex profile. OBJECTIVE: To report a clinical case consisting of Angle Class I malocclusion with deep overbite and overjet in addition to severe crowding treated with a conservative approach. METHODS: Treatment consisted of slight retraction of the upper incisors and intrusion and protrusion of the lower incisors until all crowding was eliminated. RESULTS: Adequate overbite and overjet were achieved while maintaining the Angle Class I canine and molar relationships and coincident midlines. The facial features were improved, with the emergence of a slightly convex profile and lip competence, achieved through a slight retraction of the upper lip and protrusion of the lower lip, while improving the nasolabial and mentolabial sulcus. CONCLUSIONS: This conservative approach with no extractions proved effective and resulted in a significant improvement of the occlusal relationship as well as in the patient's dental and facial aesthetics.

The Impact

Abstract Background: Desquamative gingivitis (DG) is a non-plaque-induced, blistering and painful condition occurring most frequently on the labial aspect of the attached gingiva of anterior teeth. The incidence of DG is highest around 50 years of age, and usually indicates the presence of oral or systemic diseases. The purpose of our study was to determine the impact of DG on periodontal health by recording the plaque index, gingival index and gingival bleeding index in a group of patients with DG, compared to healthy controls. Materials and methods: Recordings of specific indices were performed in a group of 26 patients with DG and compared with 24 healthy individuals. These were followed by radiographic examinations in order to assess the loss of marginal alveolar bone. Results: The results showed that patients with DG had a statistically significant increase in periodontal indices, with more gingival inflammation and plaque retention compared to the control group (p <0.05). The highest scores for gingival inflammation were recorded in patients with DG, but on radiographic evaluation the difference was related only to gender, men being more affected by alveolar bone loss in both groups (p <0.05). Conclusions: The incidence and severity of gingival inflammation proved to be higher in patients with DG, which calls for better preventive and maintenance treatment protocols in this group of patients. Early diagnosis and initial-phase periodontal treatment are very important in preventing further tissue breakdown.

Objectives: Biopure MTAD™, a new root canal irrigant has shown promising results against the most common resistant microorganism, E. faecalis, in permanent teeth. However, there is lack of studies comparing its antimicrobial effectiveness with NaOCl in primary teeth. The purpose of this study was to compare the in vivo antimicrobial efficacy of NaOCl 2.5% and Biopure MTAD™ against E. faecalis in primary teeth. Study design: Forty non vital single rooted primary maxillary anterior teeth of children aged 4-8 years, were irrigated either with NaOCl 2.5% (n=15), Biopure MTAD™ (n=15) and 0.9% Saline (n=10, control group). Paper point samples were collected at baseline (S1) and after chemomechanical preparation (S2) during the pulpectomy procedure. The presence of E. faecalis in S1 & S2 was evaluated using Real time Polymerase Chain Reaction. Results: Statistical significant difference was found in the antimicrobial efficacy of NaOCl 2.5 % and BioPure MTAD™ when compared to saline (p&gt;0.05). However, no statistical significant difference was found between the efficacies of both the irrigants. Conclusions: NaOCl 2.5% and BioPure MTAD™, both irrigants are equally efficient against E. faecalis in necrotic primary anterior teeth. MTAD is a promising irrigant, however clinical studies are required to establish it as ideal root canal irrigant in clinical practice.

The aim of this study was to evaluate the sealing ability of three different canal filling techniques. Sixty-four roots of extracted human maxillary anterior teeth were prepared using ProTaper® rotary instruments. The specimens were then randomly divided into 3 experimental groups (n=16) and 2 control groups (n=8). The root canals were filled using cold lateral compaction (CLC group), continuous wave condensation technique using the Elements Obturation Unit® (EOU group), and ProTaper obturators (PT group). For the negative control group, 8 roots were filled using lateral compaction as in the CLC group, and the teeth were covered twice with a layer of nail varnish (NCG group). Another 8 roots were filled using lateral compaction, but without sealer, and these were used as the positive control (PCG group). A glucose leakage model was used for quantitative evaluation of microleakage for 24 hours and 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 weeks. No significant difference in the cumulative amount of leakage was found between the three experimental groups at all observation times. The lateral condensation of cold gutta-percha can guarantee a similar seal of canal fillings as can be achieved by using thermal methods, in the round canals.

Very little studies were done on relationship of the dental status and the nutritional status. The present study was done to study relation between edentulism and the presence of anemia. The study was included of 46 adult patients with edentulism and same numbers of patients were taken as controls. The results were tabulated and analyzed with the help of IBM SPSS statistics 20 using student’s t test. The hemoglobin levels were lower in the edentulous patients that that of the control group. The present study had shown that the nutritional status were poor resulting in anemia in case of edentulous patients as compared to control group with the same age group.

BACKGROUND: The set of pathological changes in the stomatognathic system in the presence of a total maxillary prosthesis and a removable partial mandibular prosthesis has been described as the Combi-nation Syndrome. The main purpose of this study was to determine its prevalence and if features such as age, sex or type of mandibular edentulism are associated with the syndrome in the patients of the Odon-tologic Clinic of the of Faculty of Dentistry, Universidad de Cuenca during the academic period 2015-2016. METhODS: Cuantitative, cross sectional descriptive and correlational study. The sample consisted of 312 edentulous patients. The diagnosis of the syndrome in this study was determined by the presence of a minimum of three associated signs. We determine the prevalence of combiantion syndrome and the association between sex, age and edentulism type and combination syndrome. RESUlTS: The prevalence of combination syndrome is 21.8%. Adults 60 years or older (1.8 times higher probability) and patients who suffer from Kennedy class I partial edentulism (3.6 times higher probability than other types of edentulism), have a higher probability for developing the syndrome. CONClUSiON: The prevalence of CS was 21.8%, age and suffering from Kennedy class I partial edentulism should be considered as risk factors for developing the syndrome.
