Purpose: The aim of this study was to summarize the literature on the most frequently missing permanent teeth excluding the third molars. Study design: A search was conducted to find all the available literature (in various scientific and general databases) regarding the most commonly missing teeth with respect to ethnicity and time, as well as factors biasing this outcome. Quality assessment was done to exclude studies with inconsistent information, poor designs, or data pertaining to syndromic cases or the third molars. The role of biasing factors was as well quantitatively assessed using statistical analyses [Q-test, Egger regression, Spearman correlation coefficient, multiple linear regression, Welch t-test] (α=0.05). Results: A total of 81 reports was included. The meta-sample was heterogeneous (P=0.000, Q-test). No significant publication bias was detected (P>0.1, Egger regression). The mandibular second premolar was reported as the most commonly missing tooth in most studies, followed by the maxillary lateral (the most commonly missing in the rest). In terms of the missing share of each tooth percent of all missing teeth, the mandibular second premolar and incisors are more likely to be absent, followed by the maxillary second premolar and lateral. The absence of different teeth can be affected by the ethnicity, sample types (epidemiological or dental patients), sample sizes (only in the case of bimaxillary second premolars), and the minimum ages of pooled subjects (only in the case of the maxillary lateral and the mandibular second premolar). Conclusions: Since enrolling younger patients can bias the results, older patients should be sampled.

Rare Case Report

ABSTRACT Hypodontia is the term used to describe the developmental absence of one or more primary or permanent teeth, excluding the third molars. It is the most commonly occurring developmental dental anomaly and can be a challenge to manage clinically. Hypodontia can occur in association with syndrome or it may occur in nonsyndromic patient. Bilateral occurrence is common but it is very rare to see two bilateral congenital missing teeth in a nonsyndromic patient. This case report presents a rare occurrence of congenital bilateral missing mandibular second premolars and mandibular lateral incisors in a nonsyndromic patient.

1. Background: Loss of permanent teeth is very common, affected chewing function, speech and aesthetics; restoration of missing teeth with dental implant has several advantages, but we need thoroughly study the clinical and X ray features at the position at missing teeth, then to select the type of implant and make the best plan for the dental implant patients. 2. Materials and method: Cross-section descriptive study. From January 2009 to November 2010, study with 56 patients with 102 implants of MIS and Megagen systems at the Faculty of Odonto-Stomatology, Hue College of Medicine and Pharmacy and Vietnam-Cuba Hospital in Ha Noi. 3. Results: Distributed equally in male and female, common ages 40 – 59 (55,4%), the majority of missing teeth occurs in the lower jaw (63,8%) and especially, the teeth 36 and 46 (25,4%). The majority of missing teeth due to dental caries, dental pulp and apical diseases (64,7%) of the molar teeth (51,9%); the most position of missing tooth have enough bone for dental implants (87,3%), time of tooth loss and bone status in the position of tooth loss are related to each other (p < 0,01). Diameter and length of implant usually used 4.0 – 6.0 mm (63,7%) and 8.5 – 13.0 mm (83,3%). 4. Conclusion: Clinical and X ray features of edentulous patients has an important role in determining the type of implants and treatment planning of dental implants. Key words: Loss of permanent teeth, X ray and clinical features, Dental implant.

The incidence of dental abnormalities in the cleft lip and palate population has been reported to be much higher than in the normal population. The role of genes in the production of a cleft lip and palate, and dental anomalies is thought to be complex, with autosomal dominant, recessive, and x-linked genes all playing a role. Noncleft parents can carry some of the cleft lip and palate genes, which produce clinically subtle manifestations in their facial skeleton. The purpose of this study was to look for evidence of increased dental anomalies in the non-cleft parents of cleft lip and palate children. The dentitions of the parents of 60 children with different types of cleft lip and palate were examined prospectively to see whether or not they exhibited features found more readily in the cleft lip and palate rather than did the normal population. Their dentitions were studied to record the following dental features: congenitally missing teeth, supernumerary teeth, or morphologic changes of the crowns of the permanent teeth. The number and position of any frenal attachments were also recorded. The results of this study did not show any differences in incidence of dental anomalies from the noncleft population. There was no evidence to support the hypothesis that congenital absence of lateral incisors is a microform of cleft lip and palate. Further, these results also failed to reveal any consistent pattern in the number and position of frenal attachments.

Background: Dental agenesis is a term that refers to the absence of one or more teeth, and hypodontia refers to a severe type of tooth agenesis involving less than six or more than one congenitally missing teeth, excluding the third molars. Purpose: This aimed to report the correction of overbite by using intrusion archwires. Case: A 20-year-old female patient had class I malocclusion and deep overbite, incisor retroclination, mild mandibular crowding and agenesis of 12, 13, 14, 15, and 24. Case management: The case was treated with non-extraction using 0.022 pre-adjusted technique to level and unravel using intrusion archwires to correct the deep overbite. Conclusion: The 17-month treatment resulted in a corrected overbite, good occlusion, and good facial aesthetics.

Objective: To investigate whether high serum homocysteine (Hcy) levels is associated with the risk of developing Alzheimer’s disease (AD) by performing a meta-analysis based on updated published data. Methods: We conducted a comprehensive research using Medline (Pubmed), Scopus, Web of Science and EMBASE databases to identify all prospective studies published any time to July 7, 2020 evaluating the association between elevated Hcy levels and AD risk. Results: From an initial screening of 269 published papers, 9 prospective investigations conducted on a total of 7474 subjects with mean follow-up of 9.5 years (range: 3.7-10) were included in the meta-analysis. Eight seventy-five of these subjects converted to AD. Hcy was significantly higher in these individuals (HRadjusted:1.48, 95% CI:1.23-1.76, I2=65.6%, p<0.0001) compared with who did not convert to AD. There was a significant publication bias (Egger’s test, t=6.39, p=0.0003) and this was overcome by the trim and fill method, which allowed to calculate a bias-corrected imputed risk estimate of HRadjusted:1.20, 95% CI:1.01-1.44, Q value=41.92. Conclusions: The present meta-analysis found that having higher Hcy increases the risk of AD in the elderly and this finding is consistent with the widely suggested role of this non-proteinogenic α-amino acid in AD neurodegeneration.

Objective: Tooth agenesis is one of the most common congenital anomalies seen in humans. Although ab¬sence of one or more teeth is common, absence of multiple teeth is rare. Oligodontia is a rare developmental anomaly, involving agenesis of six or more permanent teeth, excluding the third molars. The reported preva¬lence of oligodontia in permanent dentition is 0.14%. Oligodontia can be presented as an isolated condition or as a part of a syndrome. Discussion: The present case report highlights a unique case of non-syndromic oligodontia, with agenesis of four permanent incisors, left permanent canine and right second premolar in the mandibular arch and its management with a novel fixed functional prosthetic appliance. Conclusion: Prosthetic rehabilitation is an urgent need for these kind of patients so that they do not suffer from mastica¬tory and esthetic problems which can eventually lower the self esteem of individuals.

ABSTRACT Objective: The aim was to evaluate the prevalence and distribution of tooth number anomalies in a Turkish subpopulation. Materials and Methods: A population of 2722 patients (1532 females and 1190 males; mean age, 12.33 ± 2.5 years) was retrospectively examined to determine the prevalence and distribution of the hypodontia, oligodontia, and hyperdontia using panoramic radiographs. All permanent teeth were investigated except thirds molars and the data obtained were recorded as unilateral (left or right) or bilateral according to gender. Pearson's Chi-squared and Fisher exact tests were used for difference comparisons (P < 0.05). Results: Permanent tooth anomalies were found in at least 132 (4.84%) of 2722 patients with no statistically difference between the genders, consists of 4.63% females and 5.12% males. Distribution of hyperdontia was statistically significant difference between genders, whereas distribution of hypodontia and oligodontia was no significant difference between genders. Hypodontia was the most frequently observed anomaly (3.67%), followed by hyperdontia (0.96%), and oligodontia (0.21%). Oligodontia and hypodontia were more frequent in females (3.98% and 0.26%, respectively), whereas hyperdontia was more frequently observed in males (1.68%). Maxillary lateral incisors were most common missing teeth (2.27%), while the frequency of hyperdontia was most common in premolars. Conclusion: The prevalence of teeth number anomalies was 4.84% of dental patients. Maxillary lateral incisors were most common missing teeth, while the frequency of hyperdontia was most common in premolars.

This study evaluated the role of health literacy (HL) in the self-management of diabetes. A literature search was conducted in electronic databases and studies were selected using precise eligibility criteria. A meta-analysis was conducted to estimate the HL adequacy rate, factors affecting the adequacy of HL and correlations between HL and diabetes self-management variables. Thirty-three studies were included in the analysis. The HL adequacy rate was 67% (95% confidence interval (CI) 57, 76). Compared with patients with inadequate HL, patients with adequate HL were younger (mean difference –5.2 years; 95% CI −7.2, −3.2; P&lt;0.00001), more likely to have a high school or higher level of education (odds ratio (OR) 8.39; 95% CI 5.03, 13.99]; P&lt;0.00001) and were less likely to belong to a low-income group (OR 0.36; 95% CI 0.23, 0.56; P&lt;0.00001). HL was positively correlated with self-monitoring (r=0.19; 95% CI 0.11, 0.27; P&lt;0.00001), dietary and physical care (r=0.12; 95% CI 0.07, 0.18; P=0.009), diabetes knowledge (r=0.29; 95% CI 0.09, 0.45; P&lt;0.001), self-efficacy (r=0.28; 95% CI 0.15, 0.41; P&lt;0.00001), self-care (0.24; 95% CI 0.16, 0.31; P&lt;0.00001), formal education (r=0.35; 95% CI 0.18, 0.53; P&lt;0.00001) and social support (r=0.2; 95% CI 0.07, 0.33; P&lt;0.00001). Patient age (r=−0.28; 95% CI −0.39, −0.17; P&lt;0.00001) was inversely correlated with HL. In conclusion, 67% of diabetes patients had adequate HL, with a higher rate among better educated and higher income groups. HL had a statistically significant but weak positive correlation with diabetes self-management variables.
