Effect of Dentists' Appearance Related with Dental Fear and Caries aStatus in 6-12 Years Old Children.

OBJECTIVE: The aims of this study were to determine the prevalence of dental fear, the relationship between dental fear and dental caries and the dentist appearance most likely to reduce anxiety among children. In this way, dental treatment could be made more effective by changing the dentist's appearance. STUDY DESIGN: The "Children's Fear Survey Schedule-Dental Subscale" and a questionnaire 'designed to examine the children's preferences for their dentist's appearance', were administered to 810 patients between 6-12 years of age. Patients were examined after completing the questionnaires, and their DMFT/dmft indexes were determined. Patients were divided into three subgroups according to their CFSS-DS scores. RESULTS: Among patients, anxiety scores differed significantly by age and gender (p=0.046, p=0.001). Specifically, higher anxiety scores were identified among 6- to 8-year-olds and in female patients relative to their respective counterparts. A statistically significant association between anxiety and dental caries was detected. (DMFT p=0.030/dmft p=0.015), and DMFT/dmft scores were found to be higher among patients with high levels of dental anxiety than among patients with low levels of dental anxiety. Additionally, children were highly perceptive of and exhibited strong preferences for the appearance of their dentist. CONCLUSION: Anxiety and dental caries were associated; small alterations in a dentist's appearance may reduce dental anxiety among children.

Effects of medical and mental status on treatment modalities in patients treated under general anaesthesia at the KTU Faculty of Dentistry in Trabzon, Turkey: A comparative retrospective study.

This study evaluated the differences in dental conditions and treatment modalities between disabled and non-cooperative healthy children under general anaesthesia. The data were collected from paediatric patients between 3 and 15 years of age who received dental treatment under general anaesthesia. Patients with at least one mental/physical disturbance (group 1) and other healthy non-cooperative patients (group 2) were compared with regard to gender, age, weight, and treatment time-type. The statistical analyses were performed using Fisher's exact and Mann-Whitney U tests. No significant differences were observed between the groups with regard to gender, weight and treatment-time (p>0.05). The numbers of treated teeth (p<0.01) and extractions (p<0.001) were higher in group 1 than in group 2, whereas the frequency of advanced restorative procedures for group 1 was lower than that for group 2, including preventive-resin-restoration (p<0.001), glass-ionomer-cement (p<0.05), root-canal (p<0.001) and stainless-steel-crowns (p<0.001). This study supports the hypothesis that the general condition of the patients may alter the type of treatment provided and confirms the necessity of performing preventive procedures.

Alveoler process fracture in mandibular immature permanent incisors region.

The presented case evaluates the treatment of an alveolar fracture associated with mandibular immature lower permanent incisors. An 8-year-old girl was referred to our clinic 3 hours after the trauma. The clinical and radiographic examination of the alveoler bone showed a fracture, along with the mandibular fracture and significant segment mobility and dislocation of several immature mandibular permanent incisors. These were moving together to the lingual side because of the direct trauma associated with falling from the school wall. After the application of the buccal and lingual infiltration of local anaesthesia, the dislodged bone including the lower permanent incisors, were carefully repositioned. The teeth were splinted using semi-rigid arch bars with orthodontic brackets keeping the teeth between primary molars.The splints were removed one month later and no abnormality was observed in the immature permanent incisors. After 24 months follow up, the mandibular permanent incisors were observed to have the apical closure. Treatment of alveolar fractures in growing children with immature teeth may provide beneficial healing pattern with careful semi-rigid splinting and follow up procedures.

Direct and transdentinal (indirect) antibacterial activity of commercially available dental gel formulations against Streptococcus mutans.

OBJECTIVE: To evaluate the direct and transdentinal (indirect) agar diffusion antibacterial activity of different commercially available antibacterial dental gel formulations against Streptococcus mutans. MATERIALS AND METHODS: The commercially available dental gel formulations were Corsodyl® (COG, 1% chlorhexidine), Cervitec® (CEG, 0.2% chlorhexidine + 0.2% sodium fluoride), Forever Bright® (FOB, aloe vera), Gengigel® (GEG, 0.2% hyaluronic acid), 35% phosphoric acid gel and distilled water (control). Direct agar diffusion was performed by isolating three wells from brain-heart infusion agar plates using sterile glass pipettes attached to a vacuum pump and adding 0.1 ml of the gels to each well. Transdentinal (indirect) agar diffusion was performed by applying gel to 0.2- and 0.5-mm-thick human dentin discs previously etched with phosphoric acid and rinsed with distilled water. Zones formed around the wells and the dentin discs were measured and analyzed using Kruskal-Wallis and Mann-Whitney U tests with Bonferroni correction (p < 0.01). RESULTS: Direct agar diffusion tests showed significant differences among all gel formulations (p < 0.01) except for COG and CEG (p > 0.01). COG and CEG exhibited higher antibacterial effects compared to FOB and GEG (p < 0.01) in both direct and transdentinal (indirect) testing procedures. GEG did not show any antimicrobial activity in transdentinal (indirect) testing. CONCLUSION: Commercially available dental gels inhibited S. mutans, which may indicate their potential as cavity disinfectants.
