Management of severity lesions of hypomineralized molars (MIH) with different treatment alternatives: 9-month results of a clinical trial.

The aim of this study was to evaluate the 9-month clinical performance of different materials and treatment procedures in teeth with MIH in children, and to evaluate the effectiveness of Papacarie gel as a deproteinization agent. The study included 90 children (aged 8-15) who had 189 first permanent molars with MIH were restored randomly with 4 different materials/methods. Equia Forte HT (GC, Tokyo, Japan) was used in Group 1; In Group 2, G-eanial composite (GC, Tokyo, Japan) was used with a Fuji IX (GC, Tokyo, Japan) base; In Group 3 and Group 4, EverX Posterior (GC, Tokyo, Japan) base and G-eanial composite (GC, Tokyo, Japan) were used. In group 4, deproteinization was performed with Papacarie Duo gel (F&A, Sao Paulo, Brazil). The restorations were evaluated at 3-month intervals for 9 months using modified United States Public Health Service (USPHS) criteria. The overall recall rate was 94.1% for every 3-month clinical evaluation over 9 months. A total of 9 restorations were unsuccessful. Surface roughness of Group 1 was statistically different from all other groups in all control periods (p < 0.05). Marginal adaptation of Group 2 was found to be significantly different from Groups 3 and 4 at the both of 6th and 9th month controls. There was no significant difference between the groups in terms of retention, color match, marginal discoloration and secondary caries in all control months. Restoration of MIH with Equia Forte HT is almost as successful as composites. The use of dentin replacement materials instead of glass ionomer cements as a base in composite restorations shows better results. Papacarie deproteinization showed similar success with other composite groups. This study was the first clinical study in which Papacarie was used for deproteinization in teeth with MIH and will thus contribute to the literature.

Evaluation the oral hygiene conditions, oral Candida colonization and salivary Streptococcus mutans and Lactobacilli density in a group of Beta-thalassemic children and adolescence

BACKGROUND: In this study, the prevalence and distribution of dental caries and oral hygiene conditions in a group of patients with β-TM are evaluated and the results compared to age-and gender-matched healthy patients. In addition, oral candida colonization and the density of Streptococcus mutans (S.mutans) and Lactobacilli in the total saliva are assessed. MATERIAL AND METHODS: This study involved 59 β-TM patients between 6-16 years old (mean: 11.59 ± 3.22), who applied to the Department of Pedodontics, Faculty of Dentistry, Akdeniz University, with ongoing follow-up, treatment and regular blood transfusions. All enrolled patients were diagnosed with β-TM by the Department of Pediatric Hematology and Oncology, Faculty of Medicine, Akdeniz University. As a control group, age-and gender-matched healthy 50 patients were included to the study. RESULTS: Plaque (p = 0.001), DMFT (p = 0.009) and DMFS (p = 0.039) indices were significantly higher in the β-TM patients, whereas, the oral hygiene status was significantly lower (p = 0.004). Saliva buffering capacity average was insignificantly but slightly more in β-TM patients(p= 0.131).While S.mutans values were significantly higher in the β-TM patients (p = 0.002), no significant difference was found in the Lactobacillus (p = 0.131) and Candida values (p= 0.33). CONCLUSIONS: DMFT, DMFS, Plaque and oral hygiene indices and S.mutans values were found significantly differ-ent in β-TM patients than healthy, control group patients, in this study

16-Year follow-up of an avulsed maxillary central incisor after replantation following 10-h storage: An unusual case.

Tooth avulsion is a type of dental injury defined as the complete displacement of a tooth out of the alveolar socket, and the lack of prompt treatment measures can result in the loss of function, poor quality of life, and psychological and social problems. However, several factors may not permit the immediate replantation of an avulsed tooth; therefore, delayed replantation has emerged as an alternative to meet the esthetic, functional, and psychological demands of patients. Here it was described that the successful replantation of an avulsed maxillary central incisor in a 9-year-old boy who presented at the clinic with the tooth stored in unfavorable conditions as dry and then in olive oil-milk mixture almost 10 h after the event. The tooth has remained in its socket healthy for 16 years after treatment. The patient was satisfied with both esthetics and function.

Aetiology, treatment patterns and long-term outcomes of tooth avulsion in children and adolescents.

OBJECTIVE: Tooth avulsion constituting an emergency for children and adolescents necessitates management approaches ensuring the survival of avulsed teeth. The aim of this study was to determine the causes of tooth avulsion and to examine some factors affecting the clinical & radiographic assessment of their prognosis after replantation. METHODOLOGY: The study sample was created by using archival records of patients who were referred to the Suleyman Demirel University, Faculty of Dentistry, Department of Pedodontics, with complaint of traumatic injuries, between December 1999 and 2008. The information about age, gender, time and cause of the injury, number of affected teeth, the root maturation level (mature/immature), vitality of the affected teeth, condition of supporting tissues, extra-oral time of avulsed teeth, storage media, time of replantation, type and duration of splinting, and healing process was obtained from the patients' records. RESULTS: The sample consisted of 66 traumatized children who had a total of 93 avulsed anterior permanent teeth. The age of these patients ranged from 6 to 16 years and the 9- and 10-year-old group had the highest incidence (n=25). The most frequent causes were falls (n=24; 36.4%). Thirty-three out of a total of 93 avulsed teeth (35.5%) were replanted. Of the 33 replanted teeth, 3 (9.1%) were stored in milk and 25 were stored in dry media (n=25; 75.8%). Fifteen teeth (45.5%) were replanted within 30 minutes after the injury. After clinical and radiographic evaluation a total of 12 replanted teeth (36.4%) were considered as failed. Ten of the replanted teeth had to be extracted due to progressive root resorption. Statistical analysis showed no significant relationship between the successes of replanted teeth with extra-oral period, storage media, root formation stage, and additional traumas to the supporting tissues (p>0.05). CONCLUSION: In this study, during the 9-year period, it was determined that 5.87% of all traumatic dental consisted of avulsion injuries. Thirty-three avulsed teeth in 26 patients were replanted, and 12 replanted teeth were revealed as failures. A high rate of success can be obtained when the avulsed teeth are kept under wet conditions and brought to a dental clinic as soon as possible.
