    Children's dental treatment requirements of first permanent molars with poor prognosis
    (Clinical Oral Investigations, 2022) Gürcan, Aliye Tuğçe Tanyeri; Bayram, Merve
    Objectives This retrospective study aimed to (i) survey the correlation between decayed, missing, filled teeth (DMFT), and presence of first permanent molars (FPMs) with poor prognosis and (ii) evaluate the treatment requirements.Materials and methodsSeven hundred seventy-three children with fully erupted FPMs were included in this study. DMFT for the permanent dentition, FPMs, and Global DMFT were evaluated based on clinical and radiographic evaluation. The ratio of deep dentin caries (DDC) and apical lesion presence among FPMs, including treatment requirements, were analysed. Spearman rank correlation coefficient and t tests were used for statistical analysis.ResultsThe caries prevalence was found at 61.4%, where the mean DMFT was calculated as 1.89 ± 2.15. There was a positive correlation between DMFT values and age (rs = 0.27). On the other hand, there was a negative correlation between global DMFT values and age (rs = − 0.29). Regarding treatment needs of FPM with poor prognosis, 12.03% of the teeth needed pulpectomy, 8.93% pulpotomy, 8.93% pulp capping, and 5.3% extraction. Having higher DMFT values was correlated significantly (p < 0.01) with the presence of DDC (rs = 0.50) and apical lesion (rs = 0.34). Susceptibility to DDC and apical lesions was significantly higher at mandible than maxilla (p < 0.01). The correlation was significant between DMFT values and apical lesion presence (p < 0.01).Conclusion The ratio of FPMs with poor prognosis was found high in the study group. Treatment requirements of FPMs increased with age, and pulp interventions often took part in the majority. This study successfully concluded that higher DMFT values were correlated with the presence of DDC and apical lesion.Clinical relevanceFPMs with poor prognosis demonstrate a risk factor for apical lesion presence.

    Clinical and radiographic evaluation of indirect pulp capping with three different materials: A 2-year follow-up study
    (Ariesdue Srl, 2019) Gürcan, Aliye Tuğçe Tanyeri; Seymen, Figen
    Aim Indirect pulp capping (IPC) is a treatment that preserves pulp vitality. Several materials have been used for this procedure. The aim of this study is to evaluate the radiographic and clinical outcomes of TheraCal LC (Bisco Inc., Schaumburg, IL, USA) and to compare it with mineral trioxide aggregate (MTA) (Pro Root MTA, Dentsply Tulsa, Johnson City, TN, USA) and calcium hydroxide [Ca(OH)(2)] (Dycal, Dentsply De Trey Konstanz, Germany) biomaterials in IPC treatment. Materials and methods A total of 295 teeth, including second primary molars and first permanent molars with IPC indications from healthy and cooperative children aged between 4-15 years, were included in this study. Teeth were divided into three groups according to the materials used for pulp capping. Indirect pulp treatment was applied using Dycal for 91 teeth, ProRoot MTA for 89 teeth and TheraCal LC for 115 teeth. Primary molars were restored with the compomer material, and permanent molars were restored with the resin composite material. Restorations were evaluated with the Modified United States Public Health Service (modified USPHS) criteria. Clinical and radiographic findings were evaluated for 24 months at followup. Statistics: Statistical analysis was performed using the IBM SPSS Statistics 22 (IBM SPSS, Turkey) program, with descriptive statistical methods (means, standard deviations) and Chi-square, Fisher's exact test, and Yates's continuity correction (p<0.05 significance level) to evaluate the data. Results There were no statistically significant differences between the materials (p>0.05). The respective success rates of ProRoot MTA, Theracal LC, and Dycal were 94.4%, 87.8%, and 84.6%. There was no statistically significant difference between primary and permanent teeth according to the modified USPHS criteria (p>0.05). Conclusions These results support the idea that the success of IPC is independent from the capping material. Recently produced calcium-silicate based materials can also be used for IPC. The most important factors are to apply the indirect pulp treatment carefully, avoiding bacterial contamination, and to seal the teeth with hermetic restoration. More clinical studies with longer followup periods are required for understanding the clinical efficiency of these materials.
