Dental caries has been reported in a variety of primates, although is still considered rare in wild populations. In this study, 11 catarrhine primates were studied for the presence of caries. A differential diagnosis of lesions found in interproximal regions of anterior teeth was undertaken, since they had been previously described as both carious and non-carious in origin. Each permanent tooth was examined macroscopically, with severity and position of lesions recorded. Two specimens were micro-CT scanned to assess demineralization. The differential diagnosis confirmed the cariogenic nature of interproximal cavities on anterior teeth (ICAT's). Overall results show 3.3% of teeth are carious, with prevalence varying among species from 0% to over 7% of teeth affected. ICAT's occurred in Pan troglodytes (9.8%), Gorilla gorilla gorilla (2.6%), Cercopithecus denti (22.4%), Presbytis femoralis (19.5%) and Cercopithecus mitis (18.3%). They make up 87.9% of carious lesions on anterior teeth. These results likely reflect dietary and food processing differences among species, but also between the sexes (e.g., 9.3% of teeth of female chimpanzees were carious vs. 1.8% in males). Processing cariogenic fruits and seeds with the anterior dentition (e.g., wadging) likely contributes to ICAT formation. Further research is needed on living populations to ascertain behavioral/dietary influences on caries occurrence in primates. Given the constancy of ICAT's in frugivorous primates, their presence in archaeological and paleontological specimens may shed light on diet and food processing behaviors in fossil primates.

History Of

A 3 year and 8 months old Chinese boy was referred for a consultation regarding his missing maxillary anterior teeth. He had a history of trauma to his primary maxillary anterior teeth due to a fall at the age of 16 months. Clinical examination of the patient indicated multiple carious lesions and inadequate oral hygiene. Radiographic examination revealed intrusion of the primary left lateral incisor, with evidence of damage to the permanent tooth germ. Subsequently, the patient was followed-up for almost six years during which his permanent maxillary left lateral incisor erupted exhibiting an unusual morphology. Clinically enamel hypoplasia and radiographically dens invaginatus were evident in affected tooth.

Background and Aim. Esthetic concerns in primary teeth have been studied mainly from the point of view of parents. The aim of this study was to study compare the opinions of children aged 5–8 years to have an opinion regarding the changes in appearance of their teeth due to dental caries and the materials used to restore those teeth.Methodology. A total of 107 children and both of their parents (n=321), who were seeking dental treatment, were included in this study. A tool comprising a questionnaire and pictures of carious lesions and their treatment arranged in the form of a presentation was validated and tested on 20 children and their parents. The validated tool was then tested on all participants.Results.Children had acceptable validity statistics for the tool suggesting that they were able to make informed decisions regarding esthetic restorations. There was no difference between the responses of the children and their parents on most points. Zirconia crowns appeared to be the most acceptable full coverage restoration for primary anterior teeth among both children and their parents.Conclusion.Within the limitations of the study it can be concluded that children in their sixth year of life are capable of appreciating the esthetics of the restorations for their anterior teeth.

Fresh fish processing into a dried fish is a fish processing has been done a long time, the processing of fish based traditional food processing becomes important to preserve cultural heritage in fish processing. Differences drying method in the processing can affect the taste and texture of the fish produced timber. Types of tuna used significantly different to the color produced on the dried fish . The water content produced in this study is 15:57 (w/w %), ash content 1 , 58 ( % ), mean organoleptic test (color: 3.3, taste and smell 3:35, aroma : 3:34). Preferred types of fish are tuna and the most preferred method oven method.Keyword :

The aim of this study was to evaluate the efficiency of laser therapy in post-operative sensitivity by Visual Analogue Scale (VAS) to the 57 patients after restoration with two different resins composite. In the first group (28 patients, 30 teeth) it was restored the cavity class I Black with micro-hybrid composite Filtek Z250 - Adper Single Bond (3M/ESPE). In the second group (29 patients, 30 teeth) it was restored the cavity class III Black with nano-hybrid composite Ceram X One Sphere Tec-Prime and Bond One (Etch&Rinse) (Dentsply). The restorative treatments were performed by the same practitioner on posterior and anterior teeth diagnosed with mid-sized chronic carious lesions. Total etch (etch and rinse) strategy of adhesion was used for both composite resins. The laser treatment was performed in 2 sessions at 48 hours and after 7 days, for both study groups using laser Whitening Lase II (DMC Dental). Mean scores for VAS indices decreased significantly at 48 hours and 7 days, following laser treatment for all the investigated parameters (materials, sex, age) (p [ 0.05).
