OBJECTIVE: Bond strengths of composite resin to enamel using self-etch adhesive (SEA) Clearfil SE bond system on intact enamel and enamel pre-etched with phosphoric acid were compared. The objective was to determine if the pre-etching would increase the bond strengths of the SEA systems to intact enamel and to evaluate the effect of pre-etching on bond formation of self-etch adhesives on intact enamel. MATERIALS AND METHOD: Labial surfaces of 40 caries free permanent upper central and lateral incisors were cleaned, sectioned of their roots. All specimens were mounted on acrylic block and divided randomly into four groups. In two groups the application of self-etch adhesive, Clearfil SE bond was carried as per manufacturer's instructions, composite cylinders were built, whereas in the other two groups, 37% phosphoric acid etching was done before the application of self-etching adhesives. Then the resin tags were analyzed using scanning electron microscope and shear bond strength was measured using Instron universal testing machine. RESULTS: When phosphoric acid was used, there was significant increase in the depth of penetration of resin tags and in the Shear Bond Strength of composite to enamel. CONCLUSION: The results indicate that out of both treatment groups, pre-etching the intact enamel with 37% phosphoric acid resulted in formation of longer resin tags and higher depth of penetration of resin tags of the Clearfil SE bond, and attaining higher bond strength of the Clearfil SE bond to intact enamel. © 2011 Wiley Periodicals, Inc.

Candida is the shortened name used to describe a class of fungi that includes more than 150 species of yeast. In healthy individuals, Candida exists harmlessly in mucus membranes such as your ears, eyes, gastrointestinal tract, mouth, nose, reproductive organs, sinuses, skin, stool and vagina, etc. It is known as your "beneficial flora" and has a useful purpose in the body. When an imbalance in the normal flora occurs, it causes an overgrowth of Candida albicans. The term is Candidiasis or Thrush. This is a fungal infection (Mycosis) of any of the Candida species, of which Candida albicans is the most common. When this happens, it can create a widespread havoc to our overall health and well-being of our body.

To evaluate the anti-plaque and anti-gingivitis properties of Acacia arabicacontaining toothpaste in an adult population. Sixty subjects with gingivitis were randomly assigned to a test group (Acacia arabica-containing toothpaste) or control group (regular toothpaste). An analysis of plaque index (PI), gingival index (GI) and bleeding on probing index (BOP%) were carried out at baseline and after 28 days followed by a washout period. After the washout period, the test and control groups were crossed over and the assessments were repeated. Reductions in PI, GI and BOP% were observed in the test group compared with the control group. Brushing with Acacia arabica-containing toothpaste may help inhibit gingivitis. It can be recommended for daily oral hygiene procedures.

Hemifacial microsomia is a congenital malformation in which there is deficiency in the amount of hard and soft tissues on one side of the face. It is primarily a syndrome of first and second branchial arches involving underdevelopment of the temporomandibular joint, mandibular ramus, masticatory muscles, ears and occasionally defects in facial nerve and muscles. Here, we report three cases of hemifacial microsomia diagnosed based on clinical and radiographic findings. All three cases had variable presentations ranging from the mildest form that included facial asymmetry and ear deformity to the most severe and unusual form with facial nerve paralysis and spine deformity.

An extra tooth causing numerical excess in dentition is described as supernumerary tooth, and the resultant condition is termed as hyperdontia. Hyperdontia is more commonly seen in the permanent dentition than primary one. Supernumerary tooth which resembles tooth shape and supplements for occlusion is called as supplemental tooth. We present a case with supplemental tooth in primary dentition. 2014 BMJ Publishing Group Ltd.

Here, we report a case of 9-year-old boy who came with a chief complaint of pain and fractured upper front teeth. Significant history of trauma was revealed 6 months before reporting, during playing at his school time. Proper diagnosis was made with the help of radiological investigations. The available treatment options were discussed with the patient's parents and root canal therapy, using mineral trioxide aggregate, as an apical barrier was carried out in his upper right front teeth. However, later on, the boy was aesthetically rehabilitated in relation to his fractured upper front teeth with the help of post and core and acrylic crown.

Here, we report a case of 10-year-old boy who came with a complaint of missing upper front teeth and was also concerned about his aesthetics. Significant history of trauma was present in his toddler period. Diagnosis of malformed upper right central incisor (11) by radiological investigations was carried out. Surgery was performed and there was removal of the impacted malformed upper right central incisor (11). Healing was uneventful. The patient is under follow-up for aesthetic rehabilitation to be carried out.

Cleidocranial dysplasia is an autosomal dominant condition caused by mutation of RUNX2, characterized by generalized dysplasia of the bones and teeth. Affected individuals have short stature, atypical facial features, and skeletal anomalies affecting mainly the skull and clavicle. The dental manifestations are mainly delayed exfoliation of the primary teeth and delayed eruption of the permanent teeth, with multiple impacted supernumeraries, and absence of cellular cementum. The frequency of this disorder is 1 per million individuals. Here we report a rare case of CCD in a 9-year-old male patient having most of the characteristic features of this syndrome. Interestingly, disorganized dentinal tubules were found in the roots of an extracted deciduous first molar, which seems to be a unique feature not reported previously.

Objective: To analyze the effect of proanthocyanidin (PA) treatment of the pulp chamber dentin after NaOCl and EDTA irrigation on the microleakage and interfacial morphology of adhesive restorations. Study Design: Pulp chambers of 66 extracted permanent molars were exposed. In half of the samples, pulp chamber dentin was bonded with Clearfil S3 after irrigation with normal saline(Group1a); 1% NaOCl and 17% EDTA(Group1b) or 1% NaOCl, 17% EDTA and 30% PA (Group1c) and in other half samples, pulp chamber dentin was bonded with Futurabond NR after irrigation with normal saline (Group 2a); 1% NaOCl and 17% EDTA (Group 2b) or 1% NaOCl, 17% EDTA and 30% PA(Group 2c). After adhesive procedures, Filtek Z 250 restorations were placed in the pulp chambers. Microleakage assessment was done in ten samples from each group and scanning electron microscopic examination was done in one sample from each group. Statistical analysis was done using Mann-Whitney and Kruskal Wallis tests at a significance level of P<0.05. Results: Both the adhesives showed extensive microleakage. NaOCl and EDTA irrigation had no significant effect on the microleakage of both the adhesives. PA treatment of the pulp chamber dentin after NaOCl and EDTA irrigation significantly reduced microleakage in both the adhesives. Conclusion: It was concluded that 1 minute application of 30% proanthocyanidin solution in the pulp chamber after NaOCl and EDTA irrigation improved the subsequent bonding of self-etch adhesives to pulp chamber dentin.

A poorly fitted prosthesis can give rise to a plethora of problems like pain, discomfort in mastication and speech and epulis fissuratum. Epulis fissuratum refers to reactive tissue response to excessive mechanical pressure imparted by the poor fit of prosthesis. In this article, we discuss a case of epulis fissuratum in a 69-year-old male patient.
