The Role of Malocclusion and Oral Parafunctions in Predicting Signs and Symptoms of Temporomandibular Disorders-A Cross-Sectional Study.

Background: The aim of this study was to examine to what extent malocclusion and parafunctional habits contribute to the development of signs and symptoms associated with temporomandibular disorders (TMD) in schoolchildren with mixed dentition in Croatia in a sample of 338 children, aged 9 to 15 years.

Methods: TMD signs and symptoms assessed by the clinician were joint function and pain, masticatory muscles tenderness, range of mandibular motion, and joint sounds. To evaluate subjective symptoms and parafunctions, children and parents were asked about the presence of headaches, jaw locking, temporomandibular joint (TMJ) sounds, pain during mouth opening, or bruxism, as well as parafunctions like biting pencils or nails, chewing hard candies or ice, daily gum chewing, opening bottles with teeth, engaging in jaw play, thumb-sucking, and clenching/grinding teeth.

Changes of bite force and occlusal contacts in the retention phase of orthodontic treatment: A controlled clinical trial.

Introduction: We aimed to determine whether appliance type affects changes in maximum voluntary bite force (MVBF) and the number of occlusal contacts (NOC) during retention, controlling for sex, age, and body mass index.

Methods: The sample comprised 176 examinees (70 male, 106 female) aged 14 to 20 years: 30 had maxillary and mandibular Essix retainers, 30 had wrap-around retainers, and 30 had a combination of fixed mandibular canine-to-canine retainers bonded on each tooth separately (double twisted, 0.254 mm in diameter, stainless steel ligature wire) and Essix retainer in the maxillary arch; 86 with normal occlusion were not treated.

Importance of interincisal index for predicting mesiodistal crown diameters of canines and premolars.

The aim of this study was to examine the accuracy of regression equation for prediction of the mesiodistal diameter (MDD) of the crowns of canines and premolars (C, P1, P2), and to determine whether an incisal indexs can serve as a reliable predictor. MDD and vestibulooral diameter (VOD) of the crowns of central and lateral incisors (I1, I2), C, both P1, and P2, and first permanent molars (M1) in both jaws were measured on the plaster casts of 150 subjects (75 boys and 75 girls). The obtained measurements were compared and correlated with predicted values (by linear regression equation derived previously), with respect to gender, jaw side and value of the interincisal index.

Clinical and microbiological parameters in patients with self-ligating and conventional brackets during early phase of orthodontic treatment.

Objective: To determine the effect of different bracket designs (conventional brackets and self-ligating brackets) on periodontal clinical parameters and periodontal pathogens in subgingival plaque.

Material And Methods: The following inclusion criteria were used: requirement of orthodontic treatment plan starting with alignment and leveling, good general health, healthy periodontium, no antibiotic therapy in the previous 6 months before the beginning of the study, and no smoking. The study sample totaled 38 patients (13 male, 25 female; mean age, 14.

Maximum voluntary molar bite force in subjects with normal occlusion.

The aims of this investigation were to determine whether stabilization of maximum voluntary bite force (MVBF) occurs between 15 and 18 years of age in subjects with a normal occlusion, and to assess the influence of gender, body mass index (BMI), morphological occlusion, and jaw function measured by the number of occlusal contacts, overjet, overbite, maximal mouth opening, mandibular deflection during opening, sagittal slide between the retruded contact position and the intercuspal position, and number of dental restorations. The sample comprised 60 Caucasian subjects aged 15 (15 males and 15 females) and 18 (14 males and 16 females) years with a neutral occlusion, balanced facial profile, and absence of a previous orthodontic history. Bite force measurements were undertaken using a portable occlusal force gauge on both the left and the right sides of the jaw in the first molar region during maximal clenching.

Analysis of the soft tissue profile in Croatians with normal occlusions and well-balanced faces.

The aim of the study was to test the hypothesis that there is no difference between the soft tissue profile of Croatian and white North American adults. Facial profile photographs were taken of 110 Croatians (52 males and 58 females) with normal occlusions and well-balanced faces (age 22-29 years). The findings were also compared with a white Brazilian group.

Soft tissue facial profile of normal dental and skeletal subjects in Croatian population aged 12 to 15 years.

This study was carried out on 40 lateral cephalograms of Croatian subjects aged 12 to 15 years with dental and skeletal class I. The purpose of this investigation was to determine the means and standard deviations of the soft tissue parameters in the sample of Croatian population exhibiting dental and skeletal class I and to find the correlations between investigated parameters. The investigation included a total of 11 variables of which 4 were angular and 7 linear.

Teeth eruption in children with normal occlusion and malocclusion.

The aim of this study was to assess the differences in eruption of permanent teeth (C, P1, P2 and M2) in a group of children with and without malocclusion. A sample of 1758 children (921 boys and 837 girls), aged 8-13 was randomly selected. The subjects were grouped by chronological age (11 groups) and by presence of malocclusion.

Analysis of the soft tissue facial profile by means of angular measurements.

An aesthetically pleasing and balanced face is one of the objectives of orthodontic treatment. An understanding of the soft tissues and their normal ranges enables a treatment plan to be formulated to normalize the facial traits for a given individual. The aim of this study was to evaluate the variables defining the soft tissue facial profile of a Croatian (Caucasian) sample, by means of angular measurements typically used for aesthetic treatment goals.

Analysis of the soft tissue facial profile of Croatians using of linear measurements.

One hundred and ten subjects (52 males and 58 females) between 23-28 years of age with dental Class I occlusal relationship, good soft tissue profile, and Caucasian ethnicity were selected from the population of dental students at the University of Zagreb, Croatia. The soft tissue facial profiles were digitally analyzed using linear (11 vertical and 14 horizontal) measurements made with standardized photographic records, taken in natural head position, to determine average soft tissue facial profile for males and females. The application of Student t-test showed gender dimorphism in most parameters of the labial, nasal.

[Combined surgical-orthodontic therapy for compound odontoma].

Odontogenic tumor is a rare condition in dental medicine that mostly proceeds unrecognized until the occurrence of clinical symptoms such as delayed eruption, or is incidentally detected on routine x-ray examination. The exact cause is not known, however, previous dental trauma and infection have been postulated as the potential factors in the development of odontogenic tumor. The earliest possible operative extirpation of the tumorous growth is recommended to eliminate permanent tooth impaction and to enable normal growth of the teeth.
