REASONS FOR AND PATTERNS RELATING TO THE EXTRACTION OF PERMANENT TEETH IN A SAMPLE OF THE EGYPTIANPOPULATION: A CROSS-SECTIONAL STUDY

Background and Aims: Animal models have been demonstrating that MMPs have an important function in the tooth eruption process. The aim of this study was to evaluate the association between genetic polymorphisms in MMP8 and MMP13 and delayed tooth eruption of permanent teeth. Materials and Methods: This cross-sectional study selected 216 children, 9- to 12-year-old, from public schools at Manaus, Amazonas, Brazil. During oral clinical examination, each permanent tooth emerged in the oral cavity was evaluated. Children were considered with delayed tooth eruption when at least one permanent tooth was delayed and were classified in 2 groups: children “with delayed tooth emergency” and “without delayed tooth emergency.” Saliva samples were collected from DNA extraction. The genetic polymorphisms rs17099443 and rs3765620 in MMP8, and rs478927 and rs2252070 in MMP13 were genotyped. Statistical Analysis: PLINK V1.07 ( http://pngu.mgh.harvard.edu/purcell/plink/ ) and GraphPad Prism 5.0 (San Diego, CA, USA) were used. The c2 or Fisher exact test was used to calculate genotypes and alleles distributions. To compare the mean number of delayed teeth according to genotypes, the Kruskal-Wallis test with multiple comparison Dunn test was used. The established alpha for all comparisons was .05. Results: The polymorphism rs17099443 in MMP8 was associated with delayed tooth eruption in the genotype distribution ( P = .05). In the allele distribution, the C allele was underrepresented in children with delayed tooth eruption ( P = .01; OR = 0.61, 95% confidence interval, 0.41–0.9). Conclusion: The genetic polymorphism rs17099443 in MMP8 is associated with delayed tooth eruption.

Dental Crowding

Dento-alveolar disharmony with crowding is a common reason for orthodontic treatment with not fully understood or unequivocally demonstrated causes. This study investigated the correlations between teeth dimensions, arch lengths, and crowding during the mixed dentition period. A cross-sectional study on 100 dental casts of patients with class I malocclusions was performed. Dental arches were classified as non-crowded, moderately crowded, severely crowded, and spaced. The mesio-distal widths, bucco-lingual sizes, and crown proportions of permanent teeth were assessed. The results indicated that arch length measurements showed smaller values in crowded arches. The mesio-distal dimensions of upper central incisors and lower lateral incisors were larger in patients with crowding. The bucco-lingual dimensions of upper incisors were decreased, the bucco-lingual dimensions of lower central incisors and permanent first molars were increased in crowded arches. Upper incisors and lower lateral incisors presented larger crown proportions in crowding cases. Low negative correlations were found between mesio-distal diameters of maxillary central incisors, lower lateral incisors, lower permanent first molars, and the values of arch space discrepancies. In conclusion, crowding in the mixed dentition could be associated with reduced arch lengths, increase in mesio-distal sizes of incisors and lower permanent first molars, and variations of bucco-lingual dimensions and crown proportions of incisors and lower permanent first molars.

The aim of this study was to determine the frequency and severity of dental fluorosis (DF) and the association between severity and risk factors. In a cross-sectional study, 8- to 12-year-old children, born in a Colombian district, were evaluated according to the Thylstrup and Fejerskov Index (TFI) by two calibrated examiners. Molar Incisor Hypomineralization (MIH) and dental caries (DC) were also evaluated. Ordinal logistic regression was applied p<0.05). Risk factors and lifestyle factors were collected using a questionnaire answered by parents. DF was detected in 76 (98.7%) of the children (average of 18.4 ±1.81 permanent teeth affected). Grade TF2 was the most frequently observed (34.8%); TF5 was observed in all age groups; TF6- TF7 were observed in 12-year-olds. No association was found between DF severity and DC (Odds Ratio (OR)=1.35; 95%CI: 0.56-3.26) or MIH (OR=1.39; 95%CI: 0.43-4.46). DF severity was significantly associated with use of an indoor wood stove for food preparation (OR = 9.34; 95%CI: 1.11-78.57) and use of a pea-sized volume of toothpaste (OR = 27.42; 95%CI: 1.57-477.36). Prevalence of DC was 38.1% and prevalence of MIH was 14.4%. In this population, the frequency of DF was high and severity was associated with use of an indoor wood stove for food preparation and toothpaste amount used during childhood.

Jaw Bones

Abstract: Malocclusion is one of the most common dental and oral health problems after caries and periodontal disease. Most of the malocclusions occur in adolescence and manifest as crowding teeth. Malnutrition can inhibit the growth and development of the skull and jaw bones, therefore, the permanent teeth have lack space to erupt resulting in crowding teeth. This study was aimed to determine the relationship between crowding teeth and nutritional status among adolescents in Indonesia. This was a literature review study using three databases, Google Scholar, GARUDA, and Pubmed. Keywords used were crowding, malocclusion, malnutrition, adolescent, Height for Index, BMI, nutritional status, adolescents. After being selected based on inclusion and exclusion criteria, a critical appraisal was carried out and obtained 8 cross-sectional study literatures. The review showed that there were more literatures stating that there was no relationship between crowding teeth and nutritional status among adolescents. Apart from nutritional status, there were several other factors that could affect crowding teeth in adolescents such as bad habits, history of crowding deciduous teeth, heredity, and socioeconomic status. In conclusion, crowding teeth in adolescents is influenced by nutritional status as well as other factorsKeywords: crowding, nutritional status, adolescents. Abstrak: Maloklusi telah menjadi salah satu permasalahan kesehatan gigi dan mulut yang sering dijumpai setelah karies dan penyakit periodontal. Sebagian besar maloklusi terjadi pada usia remaja dalam bentuk gigi berjejal. Status gizi yang kurang dapat menghambat pertumbuhan dan perkembangan tulang tengkorak maupun rahang yang menyebabkan gigi permanen kekurangan ruang untuk erupsi dan terjadi gigi berjejal. Penelitian ini bertujuan untuk mengetahui hubungan gigi berjejal dan status gizi pada remaja di Indonesia. Jenis penelitian ialah literature review dengan pencarian data menggunakan tiga database yaitu Google Scholar, GARUDA, dan Pubmed. Kata kunci yang digunakan yaitu crowding, malocclusion, malnutrition, BMI, adolescent, maloklusi, TB/U, IMT, Status Gizi, Remaja. Setelah diseleksi berdasarkan kriteria inklusi dan ekslusi, dilakukan critical appraisal dan didapatkan 8 literatur cross-sectional study. Hasil kajian menunjukkan terdapat lebih banyak literatur yang menyatakan tidak terdapat hubungan antara gigi berjejal dan status gizi pada remaja. Selain status gizi, faktor lainnya yang dapat memengaruhi terjadinya gigi berjejal pada remaja ialah kebiasaan buruk, riwayat gigi desidui berjejal, keturunan, dan status sosial ekonomi orang tua.. Simpulan penelitian ini ialah gigi berjejal pada remaja tidak hanya dipengaruhi oleh status gizi saja namun dapat disebabkan oleh faktor lain juga.Kata kunci: gigi berjejal, status gizi, remaja

Objectives: This cross-sectional study aimed to evaluate the frequency and risk factors associated with cusp fractures in posterior permanent teeth. Methods: Patients presented cusp fractures on posterior permanent teeth, clinically assessed in up to 7 days after the event, and requesting dental treatment at two public services were included in this cross-sectional study. Fractured teeth already treated, with antagonist absence, or with prosthesis (total or removable) were excluded. Demographic and clinical data were collected to draw the patient profiles and establish how teeth were affected individually. Statistical analysis was performed by the Fisher exact test, and uni- and multivariate logistic regression (α = 0.05). Results: One hundred and seventy-seven (177) patients from 16 to 66 years old (±41.56), from 1998 to 2016, were included in this study. Non-functional and lingual cusps presented a higher fracture than functional and buccal cusps, respectively. Fractures were more common in teeth with isthmus wider than 1/3 of the intercuspid distance and/or more than three restored surfaces. Teeth with endodontic treatment presented a higher subgingival fracture. On lingual cusps, fracture type and location were significantly associated, being that total fractures were 3.2 times more likely to occur than partial fractures, and subgingival were 3.62 times more likely to occur than supragingival fractures. Conclusion: Indications of classic protection on functional cusps (LUBL) was refuted since, generally, nonfunctional cusps fractured more than the functional cusps. However, upper pre-molars showed more fractures in functional cusps and lower molars presented more fractures on the nonfunctional cusps. In general, lingual cusps were the most fractured and were associated with a higher prevalence of severe fractures (total fractures at the subgingival level). Fractures were more common in teeth where the restoration had an isthmus wider than 1/3 of the intercuspid distance and/or involved more than three restored surfaces. Most of the patients did not show previous symptoms and signs. Overall, teeth with endodontic treatment presented a higher subgingival fracture.
