Absolutely thick molar enamel is consistent with large body size estimates and dietary inferences about Gigantopithecus blacki, which focus on tough or fibrous vegetation. In this study, 10 G. blacki molars demonstrating various stages of attrition were imaged using high-resolution microtomography. Three-dimensional average enamel thickness and relative enamel thickness measurements were record...

BACKGROUND Dentine hypersensitivity (DH) is a common finding with different prevalence rate. The aim of this study was to evaluate the prevalence of DH and associated risk factors. MATERIALS & METHODS This cross-sectional survey was done among patients coming to dental hospital. The diagnosis of DH was made as the result of both clinical examination and patient's response. A self-administered...

OBJECTIVES The objective of this study is to evaluate the efficacy of self and professionally applied desensitizing agents in relieving dentinal hypersensitivity after single direct topical application. STUDY DESIGN This was a randomized controlled trial conducted among 57 patients. 8% Arginine paste was self-applied by the subject and Gluma desensitizer was applied by investigator. Numeric r...

BACKGROUND The etiology of dentine hypersensitivity (DH) is still inconclusive and there are few studies concerning it in children. AIM To evaluate clinical, dietary, and salivary variables in children with DH complaints. DESIGN Forty-eight children were asked about DH. Data regarding dietary habits were collected from the children's parents and an examination was performed to determine den...

BACKGROUND One of many functions of the pulp-dentin complex is sensory function. Acute, situated, receding pain after the cessation of the stimulus action is called dentin pain. Dentin hypersensitivity has been described as one of the most painful and least successfully treated chronic ailments of teeth. The aim of this research was the clinical evaluation of the effectiveness of professional p...

Amelogenesis Imperfecta (AI) is a genetic disease affecting primary and permanent tooth enamel. The incidence varies between 1:700 to 1:4000. The clinical findings include enamel defects, tooth sensitivity, poor dental aesthetics, reduced vertical dimension, dentin dysplasia, and pulpal calcification. Effective treatment planning should incorporate numerous factors such as the patient’s age, di...

This study evaluated the effectiveness of carboxymethyl cellulose (CMC) hydrogel as a dental gel in delivering hydroxyapatite (HAp) to dentine tubules and reducing/eliminating dental hypersensitivity. The hydrogel was prepared by mixing solutions of CMC/ glycerol and distilled water/sorbitol then modified to contain 0%, 10%, 20% and 30% HAp. The pH of the hydrogels decreased and viscosity incre...

AIM To detect and quantify dentine sialoprotein (DSP) in the gingival crevicular fluid (GCF) of luxated teeth. METHODOLOGY Eighteen subjects were enroled and distributed as follows. Group I (n = 6, positive control): subjects with primary second molar teeth undergoing physiological root resorption. Group II (n = 6, negative control): subjects with permanent mature maxillary central incisors. ...

BACKGROUND The aim of this study was to compare the abrasivity of various commercially available toothpastes that claim to reduce dentin hypersensitivity. METHODS Dentin discs were prepared from 70 human extracted molars. The discs were etched with lemon juice for 5 min, and one half of the discs were covered with aluminum tape. Following this, they were brushed with 6 different toothpastes, ...

In order to endow environmental protection features to dentifrice, hydroxyapatite (HA) was added to ordinary dentifrice. The effects on dentinal tubule occlusion and surface mineralization were compared after brushing dentine discs with dentifrice with or without HA. The two types of dentifrice were then added to 100 µg/ml of hexavalent chromium cation (Cr(6+)) solution in order to evaluate the...
