Psychosocial and Economic Status of the Parents with Children with and without Tooth Trauma.

BACKGROUND: The main goal of this research is to try and understand influence of psychological and social factors in children with tendencies to repeat tooth trauma. SUBJECTS AND METHODS: Research included 147 patients, children of preschool and school age (88 boys and 59 girls). In the research patients were divided in two age groups: 5-8 and 9-12 years. In both groups there were 49 patients with no experience of dental trauma and 69 patients with experience of one dental trauma and 29 patients with repeated dental trauma. All patients that were involved in the study had previous experience with dental and medical treatment. Study included evaluation of dental anxiety and also factors that caused dental phobia previous their visit to the office in the children with no dental trauma compared to repeat dental trauma patients. On the whole study group differences considering sex, age and psychosocial status in the level of dental anxiety and dental fear were also measured. RESULTS: Categories of children without trauma and with one or multiple trauma showed that it is a similar sex division in the categories. In the no trauma group participation of the boys is lower (46.9%) while in the group with repeated trauma their participation is significantly higher (79.3%). Based on that the risk of repeated dental trauma is characteristic of boys. CONCLUSIONS: Results of this study show that tested psychosocial variables do not differentiate participants according to the tested groups or in other words there is no difference between tested groups in their psychosocial standing.

Molar Incisor Hypomineralization in Children with Intellectual Disabilities.

The aim of the study is to compare the frequency and the distribution of molar incisor hypomineralization (MIH) in children with intellectual disabilities. METHODS: Seventy-two children with intellectual disabilities and 72 healthy children were included in the study. They ranged in age from 5 to 18 years with the same distribution by age and sex. Standard clinical examination was performed, at a dental clinic or in the institution where the children lived, by using a dental mirror and a probe, according the European Academy of Paediatric Dentistry judgment criteria for MIH. RESULTS: Among the 72 children with intellectual disabilities, eight children (11.1%) presented MIH with 19 affected teeth. In the control group, one child (1.4%) presented MIH with two affected teeth. The difference was statistically significant (p = 0.033). There were no statistically significant differences between boys and girls. The molars, especially the first right molars were the most affected tooth. Brown defects were less common than white defects. CONCLUSION: Children with MIH should be identified because this condition is a common problem in children with intellectual disabilities.

Effectiveness of Er:YAG laser in cavity preparation for retrograde filling--in vitro study.

The purpose of this study was to determine the sealing quality of Super EBA cement in laser prepared root-end cavities in comparison with root-end cavities classically prepared with steel burrs. Two groups of three millimeter root sections were prepared. The first group was prepared with the Er:YAG laser and the second group with a steel burr mounted on a surgical handpiece. The sections were filled with Super EBA cement and tested for leakage with fluid transport techniques. The sealing quality of Super EBA cement in the classically prepared root-end cavities was better, but there was no statistically significant difference between the two preparation techniques. The possible reason for greater leakage in the laser prepared root-end cavities was probably the irregular shape of the root-end cavity.

The prevalence of idiopathic osteosclerosis and condensing osteitis in Zagreb population.

The aim of this study was to determine the prevalence of idiopathic osteosclerosis (IO) and condensing osteitis (CO) in Zagreb patient population sample according to age and sex, localization in the jaw, as well as dental relationship between IO and CO lesions. A retrospective study was performed using orthopantomograms of 1200 patients who underwent dental treatment. Descriptive characteristics of radiopacities, including the size and information concerning the tooth involved, were recorded and processed using chi2-test. A total of 114 radiopacities were identified, 34 IO in 29 subjects (16 female and 13 male, mean age 35), and 80 CO in 69 subjects (38 female and 31 male, mean age 37). There were no significant sex differences. Both CO and IO showed greater predilection for occurrence in the premolar to molar region of the mandible. Our results indicated a low prevalence of IO and CO in the population of Zagreb. Our findings support the theory that IO lesions should be considered developmental variants of normal bone architecture unrelated to local stimuli, whereas CO lesions could be considered reactive formations related to teeth with deep caries, large restoration, or pulpitis.
