“…6,7 The prevalence rates of supernumerary teeth in Caucasian populations in the permanent and primary dentition are 0.1 to 3.6% and 0.3 to 0.8% respectively. 4,6,8,9 The etiology leading to supernumerary teeth is not well understood, but there are many possible causes that include atavism, excessive growth of the dental lamina, and dichotomy of the tooth germ, heredity and genetics. 4 Supernumerary teeth are classified according to their location.…”

Objective: To determine the prevalence of permanent tooth anomalies in patients attending the graduate orthodontic clinic at the State University of New York at Buffalo. Materials and methods:Charts of 496 subjects (310 females and 186 males) met the inclusion criteria for this study. The mean ages were 16 years and 3 months for the combined gender sample that received orthodontic treatment in the graduate orthodontic clinic between 2007 and 2010. Full pretreatment records (intraoral photographs, digital study models, lateral cephalograms and panoramic radiographs) were used for the assessment. Charts were examined for these anomalies: agenesis, supernumerary, impaction and delayed tooth eruption. Subjects were categorized by gender and ethnicity. The percentages of the anomalies were assessed according to type of malocclusion, gender, race, location, tooth class and region in the dental arches.Results: Sixty-four subjects (12.9%) had at least one occurrence of delayed eruption and impaction (DEI), followed by 47 subjects (9.5%) who had at least one occurrence of agenesis, and seven (1.4%) had a supernumerary condition. Approximately 80% of the subjects had no dental anomalies. The presence of more than one anomaly was observed in 61 subjects. Twelve subjects (2.4%) had both agenesis and DEI. Agenesis tended to be more common in class II malocclusions (p = 0.012). Conclusion:The prevalence of permanent tooth anomalies was (20.4%). The percentage occurrence of DEI was the highest (12.9%) followed by dental agenesis (9.5%) and supernumerary teeth (1.4%) in the orthodontic patients at the State University of New York at Buffalo.

“…As previously reported (1,3,5,16,17), we also observed that the most frequently seen type of ST was (Table). ST may cause crowding, diastema, cyst formation, resorption, and rotation of adjacent teeth and may delay or impede the eruption of the permanent teeth, or it may be symptomless (28). In our study, 49.4% of the ST were not associated with clinical complications.…”

Some bis-benzimidazoles derivatives bearing allyl, crotyl, cinammyl, furfuryl, and thenyl groups were synthesized and their in vitro antimicrobial activity determined against gram-positive and gram-negative bacteria, and fungi by disk-diffusion method. The structures of all new compounds were identified by 1 H-NMR, 13 C-NMR, and FT-IR spectroscopic techniques and elemental analysis. All the compounds synthesized in this work were examined for their in vitro antimicrobial activities against gram-positive (Staphylococcus aureus and Bacillus megaterium) and gram-negative bacteria (Klebsiella pneumoniae and Escherichia coli ), and the yeasts like fungi (Candida globrata and Candida tropicalis). Compared to the reference substances, Cefozine and nystatin, most of the compounds showed high antibacterial and antifungal activities against studied strains with inhibition zones between 8 and 28 mm.

“…Mesiodens frequently interfere with the eruption and alignment of the maxillary incisors (9,(20)(21). They can delay or prevent eruption of central incisors, cause ectopic eruption, displacement or rotation of central incisors and labially displace incisors.…”

Purpose: Supernumerary tooth is one of the developmental problems in children. Supernumerary tooth present in the midline of the maxilla is called "mesiodens". Mesiodens present classical oral complication such as impaction of adjacent teeth, crowding, diastema formation, rotation, displacement of teeth, and occlusal interference. The treatment modality is removal of mesiodens and further observation till the permanent incisors erupt. The aim of this study is to evaluate the epidemiological characteristics of mesiodens, with an analysis of the associated clinical-eruptive complications.Materials and Methods: Thirty two patients with mesiodens were included in the present study. Radiological examination, age, sex distribution, number of mesiodens per patient, shape, size, direction of the eruption and the relationship with permanent incisors were documented.Results: The results showed that males were affected approximately 3.5 times more than females; most of the mesiodens were conical in shape (67.56%) where as the rest the others were tuberculate (32.44%). Of the 32 children, 27 (84.37%) had one mesiodens and 5 (15.63%) had two mesiodens bilaterally to midline. 12 mesiodens out of 37 (32.44%) were fully impacted. The most common complication caused by mesiodens was delayed eruption of the permanent incisors and there were 14 cases (43.75%) in such condition.Conclusion: Mesiodens as the most prevalent form of supernumerary teeth in permanent dentition is not a rare condition. Extraction of mesiodens in the early mixed dentition helps spontaneous alignment of the permanent dentition in childhood.Keywords: Supernumerary tooth, mesiodens, midline ÖZ Amaç: Artı dişler çocuklarda gelişimsel bir problem olarak ortaya çıkmaktadır. Maksilla orta hat civarında bulunan artı dişler mesiodens olarak tanımlanır. Mesiodensin komplikasyonları arasında çevredeki daimi dişin gömülü olarak kalması ve/veya sürmemesi, diestema oluşumu, dişlerde rotasyon, yer değişik-liği ve okluzyon problemleridir. Tedavisi mesiodensin çekimi ve daimi dişin sürmesine kadar takiptir. Bu çalışmanın amacı mesiodenslerin epidemiyolojik karakterlerinin değerlendirilmesidir.Gereç ve Yöntem: Çalışmaya mesiodensi olan 32 çocuk hasta dahil edilmiştir. Radyolojik muayene, yaş, cinsiyet, hastalardaki mesiodens sayısı, şekli, boyutu, sürme yolu ve daimi kesici dişler ile ilişkileri kaydedilmiştir.Bulgular: Çalışma sonuçlarına göre erkek çocuklarda mesiodens görülme sıklığı kız çocuklara oranla 3.5 kat daha fazladır. En sık görülen mesiodens şekli konik mesiodens (%67.56) olup diğer mesiodensler tüberkül şekillidir (%32.44). Çalışmaya dahil edilen 32 çocuğun 27'sinde (%84.37) bir mesiodens belirlenmiş, kalan 5 (%15.63) çocuk hastada ise bilateral 2 mesiodense rastlanmıştır. Çalışmadaki 37 mesiodensten 12'si (%32.44) tamamen gömüktür. Hastalar arasında en sık görülen komplikasyon, 14 vakada görülmüş olan daimi keser dişlerin sürme gecikmesidir.Sonuç: Erken karışık dişlenme döneminde mesiodenslerin çekimi çocukluk dönemindeki daimi dişlerin sürme ve sıral...
