Prevalence of Temporomandibular Dysfunction and its Association with Malocclusion in Children: An Epidemiologic Study

INTRODUCTION Malocclusion is one etiological factor of temporomandibular joint disorder (TMD). This study investigates the prevalence of TMD and the relationship between TMD and the type of occlusion. STUDY DESIGN A sample of 923 children (463 girls and 460 boys, ages 7-12 years old) was grouped not only by chronological age but also by gender. The information was collected on functional occlusion (anterior and lateral sliding, interferences), dental wear, mandibular mobility (maximal opening, deflection, deviation), and temporomandibular joint and muscular pain recorded by palpation. RESULTS Headache was the only symptom of temporomandibular dysfunction (TMD) reported by the children. The results showed that one or more clinical signs were recorded in 25% of the subjects, most of which were mild in character. The prevalence increased during the developmental stages. Girls were in general more affected than boys. CONCLUSIONS In this study, many subjects with TMD had malocclusions. Early treatment may be important in the prevention of severe TMD. Significant associations were found between different signs, and TMD was associated with posterior crossbite, anterior open bite, Angle Class II and III malocclusions, and extreme maxillary overjet.

Relationship between voice function and skeletal effects of rapid maxillary expansion

OBJECTIVE To evaluate the effects of rapid maxillary expansion (RME) on the vocal quality, maxillary central incisors, midpalatal suture, and nasal cavity in patients with maxillary crossbite. MATERIALS AND METHODS Coronal CT scans of 30 subjects (14 boys, 16 girls; mean age, 12.01 ± 0.75) were taken before RME (T0), and at the end of the expansion phase (T1). Voice samples of all patients were recorded with a high-quality condenser microphone (RODE NT2-A) on a desktop computer at T0 and T1. Statistical analyses were performed using a paired-sample t-test. The degree of association between the changes in the voice parameters and nasal width was assessed with Pearsons correlation. RESULTS RME treatment produced a significant increase in the transverse dimensions of the midpalatal suture and nasal cavity between T0 and T1 ( P < .05). The maximum F0 and jitter (%) results were shown to decrease statistically significantly from T0 to T1 ( P < .001 and P = .042, respectively). Between T0 and T1, shimmer (%) and shimmer (dB) exhibited statistically significant increases ( P = .037 and P = .019, respectively). CONCLUSIONS After RME therapy, voice quality differences were found to be associated with increases in nasal width.

Evaluation of patient with Holt-Oram syndrome in terms of oral and maxillofacial findings

The Holt-Oram syndrome (HOS) is a genetic disorder with autosomal dominant inheritance associated with anomalies in upper extremities and heart and affects one out of every 100,000 live births. Maxillofacial development is also affected by these skeletal abnormalities. Although there are many studies about the HOS in the literature, the data about the development of oral and maxillofacial development are very few. In this study, evaluation of a child with the HOS is made in terms of dental and gingival health, oral and maxillofacial formation, and cephalometric analysis measurements are made for the 1 st time in the literature and identified findings are discussed in company with the literature.

The effects of idiopathic hypoparathyroidism on dental development

Hypoparathyroidism cases without etiology diagnosed in the first 10 years of life are called as idiopathic hypoparathyroidism (IHP). IHP is a rare endocrinological disorder among hypoparathyroidism cases, and the anomalies accompanying it are infrequently observed. Ca ++ metabolism disorders occurring during the formation of tooth germs may cause enamel defects in teeth, enamel hypoplasia, enlarged pulp chambers, short roots, late eruptions, and missing teeth. The case presented in this article is a good example in terms of demonstrating how tooth damage ends with the commencement of treatment. Within this article, the results of a 9-year-old male IHP patient are discussed based on the literature. The said patient could not be diagnosed until the age of 18 months so developed enamel hypoplasia as well as enamel defects in this period due to abnormal mineralization, and no problems were observed in his dental tissue that formed after the ionic equilibrium was ensured following the diagnosis.

Reconstruction of orofacial injury due to a horse hoof kick: Report of a case

We report the case of an orofacial injury caused by a horse kick. Animal attacks most commonly involve domestic animals, such as dogs, cats, bulls, camels, and horses. When an orofacial injury caused by a kick from a horse occurs, it is often serious, and may even be fatal. Children are the most common victims of horse kick injuries, generally being attacked by a horse they know. The patient was successfully treated via three stages of reconstruction: surgical, orthodontic, and prosthetic.

Evaluation of inflammation during fixed orthodontic treatment

OBJECTIVE The aim of this study was to assess effects of fixed orthodontic therapy on high-sensitivity C-reactive protein (hs-CRP) level, CBC parameters and levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), urea, creatinine, sodium (Na), potassium (K), calcium (Ca), total protein (TP), and albumin (Alb). DESIGN Blood samples (7ml) were drawn at baseline, on days 1 and 7, and three months after placement of braces in the study group, while only one blood sample was drawn at baseline in the control group. Serum hs-CRP levels were measured by nephelometric method. Friedman two-way variance analysis was used to assess values with skewed distribution obtained at baseline, on days 1 and 7, in the third month. Wilcoxon rank sign test was performed if median values were unequal. RESULTS During measurement periods, there were significant increases in hs-CRP level, WBC count and neutrophil count while a significant decrease in Na level (p<0.05). K level was significantly decreased on the day 1. No significant differences were detected in other biochemical parameters evaluated. CONCLUSION Elevation in serum hs-CRP levels and neutrophil: lymphocyte ratio within first 3 months indicates that a systemic immune response develops against therapy in patients undergoing fixed orthodontic therapy.

Diagnosis and presurgical orthopedics in infants with cleft lip and palate

Cleft lip and palate are one of the most common congenital craniofacial malformations. While preoperative treatment for infants with cleft lip and palate is still a scientific debate, patients with this malocclusion usually have to be treated from infancy to adulthood. Orthodontist plays an important role in the treatment of patients with cleft lip and palate. The purpose of this review is to give information about cleft lip and palate and presurgical nasoalveolar molding.

Shear bond strength of ceramic brackets bonded to three different porcelain surfaces

Introduction: The aim of this study is to determine the shear bond strength (SBS) of ceramic brackets bonded to three different porcelain surfaces. Materials and Methods: A total of 36 porcelain crowns were used in this study. Porcelain crowns were allocated to the three groups as follows: Conventional porcelain-fused-to-metal crowns, IPS e.max ceramic crowns, and porcelain-fused-to-zirconia crowns. Porcelain surfaces were etched with 9.6% hydrofluoric acid and rinsed with a water/spray combination. Then, ceramic brackets were bonded with a light-cured composite resin. All the specimens were stored in distilled water at 37°C for 24 hours and thermocycled and loaded into a universal testing machine for testing. Any adhesive that remained after debonding was assessed and scored according to the modified adhesive remnant index (ARI). Statistical Analysis: One-way analysis of variance (ANOVA) and Tukey′s test were used to compare the SBS of the groups. The Chi-square test was used to determine the ARI scores among the groups. Results: No statistically significant difference between the ARI scores for the three types of crowns was observed. In the conventional porcelain-fused-to-metal crown group (7.09 MPa), the lowest values of bond strength were obtained. Although similar values of bond strength were found in the IPS e.max ceramic crown (8.60 MPa) and porcelain-fused-to-zirconia crown (8.93 MPa) groups, the statistically significant differences in values of shear bond strength have observed between the other groups. Conclusions: SBS of ceramic brackets bonded to different porcelain surfaces may produce different results due to the type of porcelain crown.
