Relationship of Nutritional Status With Incidence of Permanent Mandibular First Molar Caries

@#Introduction: Nutritional status is a condition of the body which is the result of a balance between food intake and nutritional needs. Good nutritional status is very important for children, but in reality there are still many malnourished children. Lack of nutrition and the habit of consuming excess food can make teeth susceptible to caries. The tooth with the highest caries incidence is mandibular first molar which is the most important tooth in mastication process. The purpose of this research is to determine the relationship between nutritional status and the incidence of caries in permanent mandibular first molar children aged 7 years in Plalangan Village, Jember, East Java, Indonesia. Methods: This is an analytic observational research with a cross-sectional approach. The sampling technique of this research is Total Sampling, which uses the entire population as the sample of this study. This research was conducted by measuring the nutritional status of BMI-for-age based on anthropometric standards from the Minister of Health of the Republic Indonesia No. 2 of 2020 and examining the oral cavity to see whether there is caries or not in the permanent mandibular first molar. Results: The results of the Chi-Square Test showed a value of 0.036. Conclusion: The result shown that thinness and overweight children have a higher caries incidence than normal weight children. There is a significant relationship between nutritional status and incidence of permanent mandibular first molar caries.

The Radix Entomolaris and Paramolaris: A Review and Case Reports with Clinical Implications

Normally, the permanent mandibular first molar has two roots, mesial and distal. However, mandibular molars may have anadditional root located either buccally (radix paramolaris) or lingually (radix entomolaris [RE]). Understanding of the presence ofan additional root and its root canal, anatomy is essential for successful treatment outcome. The aim of this paper is to reviewthe prevalence and morphology of RE and to present two cases of permanent mandibular first molars with an additional thirdroot (RE) in the Indian population. In this study, we did a clinical investigation of two cases; one case of successful endodonticmanagement of permanent mandibular first molar characterized as RE, whereas the second one is a presentation of a case ofsevere bone loss around permanent first molar with an additional third root. The presence of an additional third root in permanentmandibular first molars may affect the prognosis of the tooth if it is misdiagnosed. Thus, an accurate diagnosis and thoroughunderstanding of variation in root canal anatomy are essential for treatment success.

Study on distolingual root canal curvature on permanent mandibular first molars by the cone-beam computed tomography / 实用医学杂志

Objective To measure the curvatures of the distolingual root canals of permanent mandibular first molars by cone-beam computed tomography (CBCT). Methods The CBCT was used to collect 230 cases of mandibular first molar distalingual root from 513 patients. The images were created by 3-D reconstruction based on the BECT data. Images were analyzed by NNT image analysis software. Each tooth was captured in clinical (CV) and proximal view (PV) image, and measured by the Schneider method. Results The average curvature of the distallingual canal was (13.27 ± 8.57)° in CV, and (30.96 ± 11.63)° in PV. Most of the distallingual root in the buccolingual view was mild bending or moderate bending , and the proximal view was severe bending. The distal lingual root bending was the most common in the crown third of the root , next in the apical third of the root, in the middle third of the root. Conclusion CBCT is an effective tool for the detection of additional distolingual roots and is a valuable aid for dentists in root canal treatment.
