Regional odontodysplasia is a rare developmental anomaly involving both mesodermal and ectodermal dental components in groups of contigous teeth. RO affects the primary and permanent dentition in the maxilla and mandible or both jaws. Generally, it is localized in only one arch. The maxillary arch is affected more often than the mandibular arch. The affected teeth tend to be in a consecutive series that does not cross the midline, although some cases do not follow this pattern, as in the present case, have been documented. Radiogaphically wide pulp chambers and thin poorly defined hard tissue outlines described as a "ghost teeth" appearance, are typical features. A case of regional odontodysplasia in a 5 year old male patient is presented. The clinical and radiogaphical findings of this developmental anomaly and treatment are described.

Regional odontodysplasia is a rare, severe, and nonhereditary developmental disorder in tooth formation and involves epithelial and mesenchymal-derived dental tissue. On radiographs, affected teeth have an abnormal morphology, a hypoplastic crown, and only a faint outline of hard tissue, a condition termed “ghost teeth.” We report clinical and radiographic findings from two children with regional odontodysplasia. Using computed tomography (CT), we calculated attenuation coefficients (i.e., Hounsfield units) for affected teeth and assessed the condition of dental follicles. To measure density, regions of interest were delimited and CT values were calculated. In our two patients, the CT values for enamel were lower in affected teeth than in sound teeth, while CT values for dentin were similar for affected and sound teeth. The average CT value for dental follicles in affected teeth was about 65 to 120, which suggests that dense fibrous connective tissues or hard tissue-like structures might be present in dental follicles. Analysis of CT values may be quite useful in the diagnosis and treatment of regional odontodysplasia.

A longitudinal study was undertaken to assess the persistance of occlusal features of the primary dentition at five years into the permanent dentition at 12 years. It was found that although there was a broad measure of predictability there was variation in detail which made forecasting unreliable in the individual patient. Generally speaking, incisal overjet and overbite changed very little between the two dentitions, but those changes which occurred were in both directions, and the direction of change could not be predicted. The sagittal relationships of the dental arch were also relatively stable, but where change occurred it tended to be in a Class II direction, with the mandibular arch becoming more retroposed in relation to the maxillary arch. The prediction of crowding of the permanent dentition from a simple count of spaces in the primary dentition, while generally reliable, was not accurate in every individual patient.

ABSTRACT Planning and executing the restorative rehabilitation of a severely worn dentition is probably one of the most intellectually and technically demanding tasks faced by the restorative dentist. This article describes the rehabilitation of a 55-year-old male patient with severe loss of tooth structure. The maxillary arch was restored using fixed restorations and the mandibular arch using the integration of fixed and removable prosthodontics. The integration of fixed and removable prosthodontics in a partially dentate patient poses a challenge as well as an opportunity for the use of a partial overdenture.

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition. A midline supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise esthetics and formation of dentigerous cysts. This paper reports a rare case of the presence of a molariform mesiodens in the primary dentition. On clinical and radiographic examination, flaring of the primary central incisors was seen, with a molariform mesiodens consisting of multiple lobes or tubercles on the occlusal surface with the well-formed root. The treatment plan consisted of the extraction of the supernumerary tooth and regular observation of permanent central incisors for proper eruption and alignment.

Retention, stability and support are the most fundamental and basic principles on which the success of an entire denture relies on. However this factor is often compromised in cases of resorption. Residual ridge resorption is the reduction in size of the bony ridge under the mucoperiosteum. The rate of resorption in mandibular arch is at an increased rate as compared to the maxillary arch; but severely atrophic maxillae with large inter-ridge distance often pose a clinical challenge during fabrication of a successful maxillary complete denture because of the increased weight of the denture, retention is compromised. The present article describes a case of a completely edentulous patient who was successfully rehabilitated with a hollow denture where a simple and deviceful technique of fabricating a light-weight maxillary denture. The present article describes a case of a completely edentulous patient who was successfully rehabilitated with a hollow denture where a simple and deviceful technique of fabricating a light-weight maxillary denture was used using the hollow tubing of salivary ejector apparatus to bring the uniform hollowness.

The aim is to evaluate the effects of slow maxillary expansion on maxillary and mandibular arch, using a slow maxillary expander (SME-Leaf Expander) banded on primary second molar. Ninety patients with transverse maxillary deficiency and posterior crossbite were selected. Sixty-nine patients (33 males/36 females; 7.6 ± 1.7 years old) who underwent SME and 21 patients (10 males/11 females; 7.4 ± 1.2 years old) who were treated with rapid maxillary expander (RME). Digital models obtained pre- and post-treatment at appliance removal (9 to 11 months) were processed by means of a 3D scanner (Trios 3, 3Shape D250 laser, Copenhagen, Denmark). Interdental width in both maxilla and mandible were measured with 3 SHAPE Ortho Analyzer. Four Maxillary and four mandibular interdental width were traced and evaluated. The adequate Student’s t-test (dependent or independent) was used to compare intra and intergroups interdental width differences (p < 0.05). The efficacy of the SME was confirmed both on maxillary and mandibular arch. All the maxillary and mandibular interdental widths increased significantly (p < 0.001). The comparison with the RME group showed significant statistical differences between the two treatments with a greater increase in primary first and second intermolar and canine width for the test group (p < 0.001). SME with Leaf Expander produced statistically significant effects for the correction of transverse maxillary deficiencies with a significant indirect effect on the mandibular arch.

AbstractFrenum is one of the most variable anatomical structures present in the oral cavity which can be defined as a “fibrous band of tissue attached to the bone of the mandible and maxillae, and is 1. present superficial to muscle attachments.”1. In the present study, hundred individuals aged 18 to 40 years were selected randomly. The patients were examined (i) To assess the number, shape and attachment of the freni in the maxillary arch and (ii) To assess the number, shape and attachment of the freni in the mandibular arch in south Indian population. It was concluded that single labial frenum was more common in both the arches, buccal frenum in maxilla were multiple. Whereas, in mandible buccal frenum had single frenal attachment. V-shaped frenal attachment was more in the maxillary and mandibular arches exception being the lingual frenum which showed prevalence pertaining to fan shape.

Objective: To evaluate the dental characteristics of patients subjected to a protocol that included early secondary gingivoalveoloplasty (ESGAP). Design: Panoramic radiographs of 87 patients with unilateral cleft lip and palate (UCLP) and 29 with bilateral cleft lip and palate (BCLP) were evaluated. Missing and supernumerary teeth were also quantified on the cleft and noncleft side and in the maxilla and mandible. Crown and root malformations and tooth rotations were quantified. A subsample in permanent dentition was extrapolated to analyze canine eruption patterns. Results: A total of 48.8% of the UCLP patients presented with missing permanent lateral incisors in the cleft area and 6.1% contralaterally. A total of 4.9% presented with missing second maxillary premolars on the cleft site and 1.2% contralaterally. A total of 7.3% presented with supernumerary lateral incisors, and 45% of the BCLP cleft sites presented with missing lateral incisors, while 25% of the cleft sites presented second maxillary premolars agenesis. Five percent of the cleft sites presented with supernumerary lateral incisors. Evaluation of the subsample in permanent dentition showed that 15.5% had a canine retention and 4.4% of the canines had to be surgically exposed. A significant association was observed between canine inclination and retention but not with absence of the lateral incisor. Conclusions: The frequency of dental anomalies in this sample was similar to other cleft populations. As surgical trauma has been suggested to damage forming teeth, the results of this study indicated that ESGAP has no detrimental influence on subsequent dental development.
