The Cost of Caries in Primary Dentition: A Case Report of a Rare Cause.

A 10.2-year-old girl, accompanied by her parents, came to the Department of Jaw Orthopedics at the Clinic for Dental Medicine. Based on the initial orthopantomography, multiple tooth impactions were diagnosed.

A difference in application time between two direct orthodontic bonding methods: A prospective randomized clinical trial.

Objective: This clinical study aimed to evaluate the difference in the time of application phase, employing the conventional and modified direct orthodontic bonding method.

Materials And Methods: Thirty patients who needed orthodontic therapy with fixed appliances were randomly divided into two equal groups (n = 15): the control and experimental group, according to the bonding method applied. A total of 600 metal brackets inch slot 0.

Bleaching effect on bonding performance of composite to enamel.

This study aimed to assess the effects of dental bleaching on the immediate shear bond strength (SBS) of composite to enamel. Different bleaching methods and time intervals between bleaching and composite restoration were examined. A total of 45 enamel specimens were divided into three groups (n = 15) based on the applied bleaching protocol: in-office (A), at-home (B), and unbleached control (C).

[Analysis of antimicrobial effect of MTAD solution in infected root canal system using PCR technique].

Introduction: Clinically acceptable antiseptic should possess organolithic-mineralolithic properties and antimicrobial efficacy, and should be non-toxic.

Objective: The aim of the paper was to assess the presence of genomes of the most common microorganisms (Porphyromonas gingivalis, Agregatibacter actinomycetemcomitans, Tanerella forsythensis, Prevotella intermedia, Treponema denticola and Enterococcus faecalis) in infected tooth root canals before and after rinsing with solution of doxycycline, citric acid and detergent Tween-80 (MTAD) in patients with clinically diagnosed primary apex periodontitis.

Methods: The content of primarily infected canals before and after using the MTAD solution was used as a biological material in which the presence of microorganisms DNA was proved.

[Orthodontic management of facial asymmetry caused by early condilar fracture in a growing patient].

Introduction: There are numerous possible causes of facial asymmetry. The facial asymmetry can be summarized and divided into three main categories: congenital, developmental, and acquired, resulting from disease or trauma. The most common cause of acquired facial asymmetry is condylar fracture.

[Analysis of soft tissue thickness in persons with malocclusions of Class II division 1 and Class II division 2].

Introduction: Different malocclusions indicate different thickness of facial soft tissue.

Objective: The aim of the study was to establish the differences in the thickness of facial soft tissue profile in persons with dentoskeletal Class II/1 and II/2 relationship.

Methods: In the study we used cephalometric rendgenograms profile analysis of 60 patients aged 12-18 years of the Dental Clinic in Nis who had not previously undergone orthodontical treatment.

[Soft tissue thickness of face profile conditioning by dento-skeletal anomalies].

Introduction: Orthodontic treatment of dento-skeletal anomalies is generally based on the correction of teeth and jaws relationship, while it is expected that soft facial tissue spontaneously adapts to therapeutically achieved relationship and to accompany hard tissue changes.

Objective: To establish facial soft tissue thickness conditioning by the presence of dento-skeletal anomalies.

Methods: The study was performed at the Dental Clinic of Nis, and involved the analysis of cephalometric rendgenograms in 121 patients, aged 12-18 years, with no previous orthodontical treatment.

[Incidence of lip and palate clefts in children in Nis from 1990 to 2007].

Introduction: Cleft lip and palate is a complex congenital anomaly of the orofacial system in children.

Objective: The aim of this study was to determine the incidence of live-born children with cleft lip and/or palate compared to the total number of children born in the period from January 1, 1990 to December 31, 2007.

Methods: Epidemiological investigation was based on the records of live-born children at the Hospital of Gynaecology and Obstetrics of the Clinical Centre Nis.

[Tooth macromorphological and ultrastructural analysis of osteological material from the medieval locality of St. Panteleimon Church in Nis].

Introduction: Analysis of macromorphological and ultrastructural tooth characteristics of osteological material from the medieval site of St. Pantaleimon Church in Nis provides us with insight on the life, nutrition and habits of medieval population, as well as the structure and composition of their teeth.

Objective: The aim of this research, based on the tooth inspection of skeletal remains from the medieval site of St.

[The influence of size and structure of metal orthodontic bracket base on bond strength on tooth enamel].

Introduction: The factors which may influence the bond strength of the applied orthodontic brackets on the tooth surface are the size and structure of the bracket base.

Objective: The aim of the paper was to investigate the influence of size and shape of different types of brackets on bond strength on the enamel and analyze the remaining quality of adhesive material on the tooth surface after debonding of orthodontic brackets (adhesive remnant index - ARI).

Methods: In this study, three types of metal brackets of different sizes and shapes of Dentaurum manufacturer were used (Utratrimm, Equilibrium 2, Discovery, Dentaurum, Inspringen, Germany).

[Ultrastructural investigation of root canal dentine surface after application of active ultrasonic method].

Introduction: The basic work principle of all ultrasonic techniques is the piezoelectric effect of producing high frequency ultrasounds of small length, which are transmitted over the endodontic extensions or canal instruments into the root canal. When in contact with the tissue, ultrasonic vibrations are converted into mechanical oscillations. Ultrasonic waves and the obtained oscillations along with the synergic effect of irrigation bring about the elimination of smear layer from the root canal walls.
