The problems of anterior teeth include dental plaque, dental caries, and fracture, which are usually treated with common composite resin clinically. Although good repair effect can be achieved, patients are prone to anterior tooth sensitivity after surgery. Therefore, the purpose of this study is to analyze the cosmetic effect of nanocomposite resin on anterior teeth. Up to 176 patients (176 teeth) undergoing anterior dental cosmetic restoration in our hospital were selected and assigned to the LR group ( n = 88 ) and the NR group ( n = 88 ) according to patients’ voluntary choice of prosthetic materials. The LR group was cured with light-cured composite resin, while the NR group was cured with nanocomposite resin. By comparing the related indexes of patients in the two groups, it was discovered that in the NR group, the excellent and good rate and patients’ evaluation of the repair effect were higher, while the periodontal attachment, gingival index, dental plaque index, VAS score, and the incidence of tooth sensitivity were lower, all P < 0.05 . The results indicated that the nanocomposite resin had significant cosmetic effect on anterior teeth and had application value.

ObjectivesWe examined the trend in the number of missing teeth in a Japanese community over a 10-year period and the potential associated explanatory factors.DesignProspective cohort study.SettingA population-based study conducted in 2007, 2012 and 2017 in Japan (Hisayama Study).ParticipantsResidents of a Japanese community aged 40–79 years undergoing dental examination in 2007 (n=2665), 2012 (n=2325) and 2017 (n=2285).Outcome measuresThe number of missing teeth, periodontal condition, dental caries experience, dental plaque index and oral health behaviours were evaluated each year. The longitudinal analysis of variation in these factors were assessed using mixed models.ResultsThe age-adjusted and sex-adjusted mean number of missing teeth decreased with time (6.80 in 2007, 6.01 in 2012 and 4.99 in 2017). The mean clinical attachment level (CAL), prevalence of periodontitis and dental plaque index decreased over the study period, while dental caries experience slightly increased. The level of oral health behaviour increased over time. Poisson mixed models showed that changes in mean CAL and dental caries experience were positively associated with the change in the number of missing teeth over time. Linear mixed models showed that changes in dental plaque index and no regular dental visit were positively associated with changes in mean CAL.ConclusionsThese findings suggest that a decreasing trend regarding the number of missing teeth in Japan might be associated with improvements in the periodontal condition due to changes in oral hygiene level and oral health behaviour.

Back ground: Dental caries and periodontal disease were the most common andwidely spread diseases affecting children. The nutrition may be one of the factorsaffecting the severity of the oral diseases. The Aims of this study was theassessment of the following oral diseases (dental caries, gingivitis) in addition toassessment of oral hygiene among 4-5 years old children in Karbala city –Iraq.Furthermore, nutritional status was assessed in relation to oral diseases.Materials and methods: A sample of 658 children (350 males, 308 females) agedfour and five years old was selected randomly from the fourteenth kindergartensin Karbala city. Diagnosis and recording of dental caries was followed the criteriaof WHO 1987. Dental plaque was assessed using plaque index of Silness and Loe,1964. Gingival health condition was assessed using gingival index of Loe andSilness, 1963. The assessment of nutritional status was performed usinganthropometric measurement (height and weight) according to Body mass indexindicator with -2SD cutoff point.Results: Caries prevalence was found to be (83%) of the total sample the mean rankvalue of dmfs was higher among boys in comparison to girls with statistically nosignificant difference (P>0.05). The value of dmfs increased with age withstatistically highly significant difference (p<0.01).The mean rank values of dentalplaque and gingival indices for total boys were found to be higher than total girlswith statistically highly significant differences (P<0.01). Recording of this studydemonstrated that 100% of children had dental plaque and gingival inflammation.Positive highly significant correlations were recorded between dental caries withdental plaque and gingival indices. The prevalence of malnutrition described byBody mass index indicator was (3.2%). According to nutritional status indicatorBody mass index-for-age, it was found that the wasted children had higher valueof dmfs than well nourished children with statistically no significant differences(P>0.05). The plaque and gingival indices were higher among well nourishedchildren than among wasted children with statistically highly significantdifferences (P<0.01).The correlation coefficient between body mass index withdental caries, plaque index and gingival index were very weak and statistically notsignificant (p>0.05).Conclusions: High prevalence of dental caries and gingivitis was recorded indicatingthe need of public and preventive programs among kindergarten children.

Background/Aim. Diabetes mellitus (DM) as a complex metabolic disease influences functioning of numerous organs. Therefore, frequent diabetic complication is chronic periodontitis. The aim of the study was to investigate the influence of various risk factors, like age, sex, duration of DM, oral hygiene, on oral manifestations of diabetes. Methods. The group of diabetics included 52 adult patients, 18-79-year of age, both sexes (33 females, 19 males) out of which 35 patients were with diabetes mellitus type I and 17 with type II. Mean age of the patients was 54.6 years and the mean duration of diabetes was 11.1 years. The controls consited of 67 volunteers from the city of Belgrade, 19-24-year of age, both sexes (47 females, 20 males) with no paradonthopathy and non-systemic diseases. Estimation of periodontal status of the patients was performed by measuring dental plaque index, gingival index and periodontal pockets' depth. Results. The results suggest an increased incidence and severity of periodontitis in diabetic patients. It was established that duration of diabetes, patients' age and bad oral hygiene had a negative influence on status of remained teeth in diabetics, while the sex had no influence on parameters monitored. Conclusion. Indices of oral hygiene level and periodontal status (dental plaque index, gingival index and periodontal pockets' depth) were significantly worsened in patients with diabetes. Negative influence on remained teeth had patients' age (>50 years), duration of diabetes (> 20 years) and bad oral hygiene. About half of the patients had a total or partial bridge suggesting that periodontitis is significant complication of diabetes mellitus.

Abstract Background: To clinically evaluate the efficacy and safety of a primer that contains taurine and self-bleaching patches containing 3.0% hydrogen peroxide.Methods: Overall, 55 participants were selected in this double-blinded randomized clinical trial between March and May 2019. Bleaching patches containing 3.0% hydrogen peroxide were attached using the primer on the labial surface of the upper six anterior teeth for 30 min once daily. △E* values of color changes were measured using Shade Eye NCC for determining the efficacy of bleaching on days 3, 5, 7, and 10 before and after attachment. The safety was assessed using gingival index and visual analog scale for tooth sensitivity and gingival irritation, respectively.Results: △E* values were visibly detected from day 7 after the attachment of patches, and the bleaching effect was identifiable. No statistically significant difference was observed in the gingival index (p = 0.069), tooth sensitivity (p = 0.983), and gingival irritation (p = 0.518).Conclusions: When the self-bleaching patches using 3.0% hydrogen peroxide with the primers were attached for 30 min once daily, visible bleaching effect was observed from day 7 of attachment, and it was verified to be safe for use without any significant adverse effect.Clinical Relevance: This study was conducted after securing safety for clinical trials.Trial registration: ISRCTN63650330

Keeping in mind the final result is the basis of any type of treatment, especially those in which the morphology, size and proportion of the anterior teeth will be changed. This is where a good treatment plan based on a diagnostic wax-up tested with a mock-up and approved by the patient becomes crucial. This case report aims to exemplify how to transfer the diagnostic information to the patient’s mouth and direct it not only to the restorative dentistry, but also to the surgeon when performing the crown length. Diagnostic waxing was performed by the laboratory technician, obeying anterior posterior incisal and gingival criteria and curvatures, which were transported to an aesthetic guide through mock up to mark the surgical points. Then, surgery to increase the clinical crown with bone access and after healing, direct venners in composite resin also guided by waxing. In conclusion, a workflow can be established using the wax-up / mock-up that serves as a guide for the periodontist in the approach to surgical lengthening of the crown and for the rehabilitator who uses it to produce changes in the shape of dental dimensions .

Sugary carbohydrate foods have long been associated with increased risk of dental caries formation, but the dental health impact of starchy carbohydrates, particularly those with a high glycemic index (GI), has not been well examined. Aim: To investigate the effect of different starchy foods varying in their GI, on acute changes in dental plaque pH. Methods: In a series of sub-studies in healthy adults, common starchy carbohydrate foods, including white bread, instant mashed potatoes, canned chickpeas, pasta, breakfast cereals, white rice, and an oral glucose solution were consumed in fixed 25 g available carbohydrate portions. The change in dental plaque pH was assessed postprandially over 1 h and capillary plasma glucose was measured at regular intervals over 2 h. Results: Higher GI starchy foods produced greater acute plaque pH decreases and larger overall postprandial glucose responses compared to lower GI starchy foods (white bread compared with canned chickpeas: −1.5 vs. −0.7 pH units, p = 0.001, and 99 ± 8 mmol/L min vs. 47 ± 7 mmol/L min, p = 0.026). Controlling for other food factors (food form and nutritional composition), lower GI versions of matched food pairs produced smaller plaque pH excursions compared to higher GI versions of the same food. Using linear regression analysis, the GI value of starchy carbohydrate foods explained 60% of the variation in maximum plaque pH nadir and 64% of the variation in overall acute dental plaque pH excursion (p < 0.01). Conclusion: The findings imply that starchy foods, in particular those with a higher GI, may play a role in increasing the risk of dental caries.

Abstract Background Toothbrushing is an important yet neglected behaviour that affects the oral health of preschool children. Little is reported on parental supervision, an essential aspect of routine effective toothbrushing in this age group. The aim of this study was to evaluate pre-schoolers’ toothbrushing behaviour including parental involvement and its association with their oral health. Methods This was a cross-sectional study. A total of 92 preschool children (4–6 years) were invited to participate with their parents/guardians. Nine parameters of toothbrushing behaviour were assessed from parental responses (questionnaire) and observation of child and parents/guardians (video recording). Oral examination included recording plaque, gingival and dental caries indices. BORIS software was used to assess toothbrushing parameters and Smart PLS was used to perform association with a second-generation multivariate analysis to create models with and without confounding factors. Results Girls were slightly more (53%) than boys (47%). Children aged 4 years were slightly more in number (38%), followed by 6-year-olds and 5-year-olds. Nearly, 90% parents had tertiary education and 46% had more than 2 children. Differences were recorded in the reported and observed behaviour. Thirty-five percent parents/guardians reported using pea-size toothpaste amount but only 28% were observed. Forty percent reported to brush for 30 s–1 min, however 51% were observed to brush for 1–2 min. Half the children were observed to use fluoridated toothpaste (F < 1000 ppm) under parental supervision (11%). The mean (SD) plaque score reduction after toothbrushing was 10.80 (2.46), mean pre-brushing plaque score was 90.3 (10.2), mean gingival index was 0.89 (0.65) and mean dental caries status (ICDAS(1–6)) was 18.87 (12.39). Toothbrushing behaviour in terms of toothbrushing technique, duration, pattern and frequency, toothbrush type and grip type, toothpaste type and amount, post-brushing mouth rinsing and parental involvement contributed significantly to plaque score change (86%), dental caries status (73%), gingival index (66%) and pre-brushing plaque score (31%). The significant confounding variables had a small influence on oral health of preschool children. Conclusions Preschool children’s toothbrushing behaviour was inadequate while their oral health was poor, with a significant association between the two parameters.
