Estimation of Maximum Occlusal Bite Force of School-going Children in Different Dentition: A Cross-sectional Study.

Background: Bite force is an important indicator of the clinical state of mastication and its efficiency. Bite force measurement using a gnathodynamometer is a reliable method to assess the biomechanical properties of the masticatory system. It varies with different geographic populations and physiological and environmental factors. Aim: To estimate the maximum occlusal bite force (MOBF) in school-going children of Hyderabad city at different dentition periods and to correlate with different variables. Materials and methods: A total of 392 school-going children in the age range of 3-13 years were selected following selection criteria (214 males and 178 females). They were divided on the basis of the dentition period. Demographic details along with general physical parameters such as height, weight, and maximum mouth opening (MMO) were recorded in a predesigned proforma. Maximum bite force was measured using a digital bite force instrument. Results: Maximum occlusal bite force (MOBF) was 18.04 N in primary dentition of age 3-5 years, 47.64 N in mixed dentition of age 6-11, and 108.39 N in permanent dentition of age 12-13 years. The magnitude of bite force was observed to be directly proportional to age, height, weight, and dentition period. Males had greater bite force than females in all three dentitions. However, the difference was significant only in mixed dentition (p < 0.05). Of all the dentition bite force was significantly higher in permanent dentition.Bite force showed an inverse relation with body mass index (BMI) in primary and mixed dentition but a positive correlation was seen with permanent dentition. The mean MMO in males was slightly higher when compared to females. It increased with an increase in the dentition stage. Conclusion: Bite force is multifactorial. It has a significant correlation with physiologic and morphologic factors that influence the values of bite force. How to cite this article: Mutt NH, Mallela George MK, Nallanchakrava S, et al.

Marsupialization of odontogenic keratocyst using thermoform surgical splint in a pediatric patient, with 3-year follow-up.

Odontogenic keratocyst (OKC), also known as keratocystic odontogenic tumor, is categorized as one of the developmental epithelial cysts, which accounts 10%-20% of all cystic lesions in jaws. Considering its high recurrence rate, combative treatment modalities such as enucleation and jaw resection are suggested. This case report aims to emphasize clinical, radiological and histological overview of OKC with conservative approach marsupialization using thermoform surgical splint in a 9-year-old female patient with no recurrence at 3-year follow-up.

Comparative Evaluation of the Fracture Strength of Pulpotomized Primary Molars: An In Vitro Study.

PURPOSE: This study evaluates the fracture strength of pulpotomized primary molars restored with amalgam, miracle mix, cermet, resin-modified glass ionomer cement, and nanocomposites. MATERIALS AND METHODS: Fifty primary first and second molars were collected for this study. All the teeth were randomly divided into five groups (n = 10). Standard pulpotomy cavities were prepared. Teeth were air dried and the canal orifices were capped with a layer of zinc oxide eugenol. A lining of calcium hydroxide was placed over it. Amalgam, miracle mix, cermet, resin-modified glass ionomer cement, and nanocomposite were placed in groups I, II, III, IV, and V, respectively. All the samples were then subjected to the fracture strength test using the universal testing machine and the results were statistically analyzed. RESULTS: All the groups were compared by the ANOVA one-way test which indicated that there were statistically significant differences among the five groups. CONCLUSION: Nanocomposites can be considered to be the best restorative material in terms of fracture strength among amalgam, miracle mix, cermet, and resin-modified glass ionomer cement.

An Unexpected Encounter with Foreign Body in the Primary Teeth and Its Management.

Clinicians may come across strange situations when they accidentally notice foreign bodies in the root canals of the teeth. This foreign body entrapment is more common in children because of the habit of placing various objects into the tooth, particularly in the cases of open carious lesions. Sometimes, these foreign objects may act as an impending source for pain and infection. Even though accidental insertion is the main etiological factor, there are other possibilities such as self-injurious habits and dental neglect which should be ruled out by thorough history. The present article describes two cases of typical etiology for foreign body lodgment and its management in the primary teeth.

Evaluation of pH, buffering capacity, viscosity and flow rate levels of saliva in caries-free, minimal caries and nursing caries children: An in vivo study.

BACKGROUND AND AIM: The present study was undertaken to evaluate the pH, buffering capacity, viscosity and flow rate of saliva in caries free, minimal caries and nursing caries children and to evaluate the relationship of these on the caries activity of children. MATERIALS AND METHODS: A total of 75 school children of age group between 4 and 12 years were selected and divided into three equal groups: Group I, Group II and Group III, consisting of 25 subjects each. Group I included caries-free subjects, Group II included subjects with minimal caries and Group III included subjects with nursing caries. Saliva samples were collected from all subjects and were estimated for flow rate, pH, buffering capacity and viscosity. RESULTS: There was a significant decrease in the mean salivary flow rate, salivary ph and salivary buffer capacity and a significant increase in the salivary viscosity among caries-free subjects, subjects with minimal caries and subjects with nursing caries. CONCLUSION: The physicochemical properties of saliva, such as salivary flow rate, pH, buffering capacity and viscosity, has a relation with caries activity in children and act as markers of caries activity.
