AbstractThe tooth shape deviations are rare dental anomaly described in premolars, characterized by to show simultaneously an increased mesio-distal dimension and decreased bucco-lingual dimension when compared with other normal teeth. The presence of such teeth with variation in size may be related to malocclusions, since there is a reduction in circumference of the dental arch. This report describes a rare case of bilateral tooth shape deviations in the two mandibular first premolars and discusses the prevalence of this condition and the eventual clinical consequences associated with this dental anomaly.

Congenitally Missing

AbstractHypodontia is the congenital absence of less than six teeth because of agenesis. Congenital absence of tooth (hypodontia) from the dental arch, may occur with any tooth, most commonly being third molars, however, absence of permanent mandibular canine is rare. The absence of teeth may be unilateral or bilateral. There are reports showing unilateral occurrence of permanent mandibular canines but agenesis of bilateral mandibular canines is not well documented in the literature and comprehensive review of literature shows paucity of data pertaining to this anomaly. Here we report one such rare case of congenitally missing mandibular permanent canines bilaterally.

Introduction: The objective of this clinical case report is to describe the presence of bilateral fourth molars. The occurrence of supernumerary teeth (ST) is a relatively unusual dental anomaly., It is even more unusual to find patients with distomolar teeth also denominated fourth molar teeth. Presentation of the case: This article describes a clinical case of a 24-year-old patient presenting with a maxillary fourth molar, who was diagnosed by dental x-ray, and surgical resolution of the case. Conclusion: Tooth extraction surgery was the clinical procedure chosen to treat the impacted tooth.

Dens Invaginatus

ABSTRACT Dens invaginatus is a dental anomaly caused by an invagination of enamel that affects in most of the cases the crown of the tooth. The treatment depends on the degree of invagination and morphological involvement. This report describes a dental anomaly affecting the permanent lower lateral incisor of a 13-year-old patient, which resulted in swelling, pain, and dental impaction. The initial radiographic examination suggested a gemination, a fusion with a supernumerary tooth or a dens invaginatus extending to the root. For more accurate diagnosis and treatment plan of this anomaly, computed tomography scan was performed, which revealed the presence of enamel in the root. Due to pain and the impossibility of performing an orthodontic traction, the treatment of choice in this case was dental extraction. The final diagnosis was confirmed by histopathological examination and revealed the rare occurrence of a radicular dens invaginatus.

BACKGROUND: The occurrence of multiple supernumerary teeth in individuals without any associated syndrome is rare. Supernumerary teeth may occur in any region of the dental arch and are frequently observed in the maxillary region. But the occurrence of distomolars is rare, particularly mandibular distomolars are extremely rare. CASES PRESENTATION: In this paper, we present a series of case reports of maxillary and mandibular distomolars. CONCLUSION: The occurrence of distomolars is rare, but when detected patients should be kept under observation.

Impaction of maxillary central incisors is frequent in dental practice. However its management is challenging because of its importance in aesthetics. Supernumerary teeth are the most common dental anomaly that can cause impaction of adjacent teeth, crowding, diastema, rotation and displacement of teeth. We report a case of 13 year old male with an impacted supernumerary tooth in the maxillary anterior region, which was interfering with the eruption of the permanent, left central incisor. The impacted supernumerary tooth was surgically removed. With the application of an orthodontic traction, impacted left maxillary central incisor was brought down to its proper position in the dental arch.

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.

Dens Invaginatus

Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis. The invagination ranges from a slight pitting (coronal type) to an anomaly occupying most of the crown and root (radicular type). Although a clinical examination may reveal a deep fissure or pit on the surface of an anterior tooth, radiographic examination is the most realistic way to diagnose the invagination. The objective of this case presentation is to report a rare case of radicular dens in dente, which is a rare dental anomaly.

Shape deviation is one of the major issues in fabricating a part using Additive Manufacturing (AM) technology. During the prototype fabrication process, slicing induced conditions play a significant role in varying shape deviations. This paper provides a novel technique for the estimation and simulation of shape deviation and provides a foundation to estimate the combined effect of oversize and undersize fabrication conditions on the same layer. The research described is the initial efforts to develop a shape deviation model regarding oversize, undersize, equal size and mixed size situations. To estimate and simulate the shape deviation, an algorithm is developed and examined with seven example tessellated prototypes. The advanced program will help the user to determine the different shape deviation information during slicing stage with different preprocessing parameters. The results show that the developed methodology is robust and work as an efficient alternative to shape deviation studies.
