There are several reasons why pediatric dentist should understand the development of dental occlusion. One of the major objectives of orthodontic treatment is to correct occlusal problems. Much of the need for this treatment could be avoided if children received the proper dental care at earlier ages. Development of occlusion is a genetically and environmentally conditioned process, which shows a great deal of individual variations, and consequently, for the development of an acceptable occlusion, quite a remarkable co-ordination of different events is necessary. The development of occlusion depends on a number of conditions, like muscular pressure, habits, availability of space, etc. This development is coincident with the growth of all tissues associated with the dental apparatus, including the nose, maxillary sinuses, facial bones and muscles. Failure in one part of the development process may lead to anomalies, or else may be compensated for by other developmental processes. Thus Proper care of the developing deciduous and permanent teeth, both at the dental office and at home, is important for the appropriate development of occlusion. and timely diagnosis followed by appropriate interception can prevent any developing malocclusion. This article is an overview which depicts (1) periods of development of occlusion, (2) outline the development of normal occlusion in the pediatric patient and (3) explain what occlusion of the teeth is and why it is important.

Abstract. Introduction: The deciduous tooth period is an important period in child development. Premature loss of deciduous teeth is defined as the loss of deciduous teeth before they approach the eruption of permanent teeth. The prevalance of premature loss offered in several studies obtained was between 4.3% and 42.6%. Method: An 10 years-old-boy accompanied by her mother came to RSGMP Unjani, complaints of lower right nack teeth missing because they have to extracted since 3 mouth ago. Tooth have been extracted because of caries. Result: Result of clinical examination was found premature loss teeth 75, 74, and 85. The space in Moyers analysis was +0.2 mm in region 3 and +0.1 mm in region 4. Patient was treated with a fungsional removable-space-maintainer on teeth 75, 74, and 85. Conclusion: The results of premature loss is excess space in the arch, so to prevent further occlusion abnormalities in child’s growth and development process, we need a special appliance that is used to protect the space due to premature loss of deciduous teeth.

Background and Objective: Dental study casts play a vital role in the diagnosis and treatment planning of various orthodontic cases. This study was carried out to compare the tooth widths, arch widths, and arch lengths in Class-I normal dentition to those in Class-I and Class-II crowded dentition in an effort to improve treatment planning and to eventually reduce treatment duration. Methods: Total 170 patients, 12 to 40 years of age with a complete set of permanent teeth till 1st molars; who presented to the Orthodontics Department at Armed Forces Institute of Dentistry (A.F.I.D), Rawalpindi from Sep 2019 to Feb 2020, were included in the study. Non-probability purposive method of sampling was used. The dental casts obtained were used to measure tooth widths, arch widths, and arch lengths. Subjects were classified into Class-I normal and Class-I and Class-II crowded occlusion and comparison of the sum of tooth widths, arch widths, and arch length discrepancies were determined among the three occlusion groups. Data was analyzed in SPSS version 21 and independent samples t-test was used to differentiate the variables of interest. Results: Out of 170 subjects, 73 (42.9%) subjects had Class-I normal occlusion while 97 (57%) had Class-I and Class-II crowded occlusions. No statistical difference was found between the occlusal groups with regard to the sum of tooth widths, inter-canine widths, inter-first premolar widths, inter-second premolar widths and inter-molar widths. However, a remarkable difference was observed between the occlusal groups with respect to arch perimeters and arch length discrepancies (p = 0.000 and 0.000 respectively). Conclusions: Results of the current study indicate that crowding of teeth occurs as a consequence of decreased arch perimeters which may lead to increased arch length discrepancies. However, no prominent difference was noticed in the sum of tooth widths and arch widths among different occlusal groups. doi: https://doi.org/10.12669/pjms.37.2.3240 How to cite this:Shafique HZ, Zaheer R, Jan A, Fazal A.

ABSTRACTOsteomas are benign osteogenic tumors that are seen in the facial bones, but uncommonly in the mandible. In the facial bones, both central and peripheral osteomas have been described. Peripheral osteomas have been described to occur in the frontal, ethmoid, and maxillary sinuses but are not common in jawbones. When in the mandible, they are usually found over the angle and inferior border of the mandible. We report on a solitary peripheral osteoma located unusually in the sigmoid notch of the left mandible causing facial asymmetry.

Objective To achieve sufficient velopharyngeal function and maxillary growth for patients with unilateral cleft lip and palate (UCLP), the authors have designed a new treatment protocol for palate closure involving early two-stage palatoplasty with modified Furlow veloplasty. Details of the surgical protocol and the outcomes of the dental occlusion of patients at 4 years of age are presented. Design and Setting This was an institutional retrospective study. Patients Seventy-two UCLP patients were divided into two groups based on their treatment protocols: patients treated using the early two-stage palatoplasty protocol (ETS group; n = 30) and patients treated using Wardill-Kilner push-back palatoplasty performed at 1 year of age (PB group; n = 42). Interventions The features of the ETS protocol are as follows: The soft palate is repaired at 12 months of age using a modified Furlow technique. The residual cleft in the hard palate is closed at 18 months of age. Lip repair is carried out at 3 months of age with a modified Millard technique for all subjects. Results The ETS group showed a significantly better occlusal condition than the PB group. The incidence of normal occlusion at the noncleft side central incisor was 7.1% in the PB group; whereas, it was 66.7% in the ETS group. Conclusion The results indicate that the early two-stage protocol is advantageous for UCLP children in attaining better dental occlusion at 4 years of age.

Objective: assessment of dental caries intensity in children with disturbances in tooth formation living in radiologically contaminated territories as a result of the Chornobyl NPP accident. Materials and methods. Children aged 6-14 years old (n = 1470) suffering from disturbances in tooth formation (DTF) with the residents of radiologically contaminated territories (n = 528) among them were enrolled in the study. The DTF subtypes were assayed, namely the systemic enamel hypoplasia (SEH) and molar incisor hypomineralisation (MIH). Personal radiation history was recorded. Intensity of caries and caries of surfaces in the mixed (i.e. transitional) occlusion (df+DMF, dfs+DMFS coefficients) and permanent occlusion (DMF, DMFS coefficients) was identified. Results. Caries intensity in the exposed children suffering DTF with mixed and permanent dental occlusion was significantly higher vs. either in children exposed to ionizing radiation with no DTF or in the control group (р < 0.001, р < 0.001 and р < 0.05, р < 0.001 correspondingly). The highest caries intensity of the permanent teeth was revealed in the residents of contaminated territories suffering SEH (6.95 ± 2.3) vs. cases of MIH (5.68 ± 1.97) as a result of nonsymmetrical teeth involvement. Conclusions. The highest values of df+DMF, dfs+DMFS coefficients were diagnosed in children with a mixed dental occlusion aged 6-14 years old living on territories contaminated as a result of the ChNPP accident as compared to the not exposed subjects and control group (7.2 ± 2.07 and 8.98 ± 2.4, р < 0.001). A very high intensity of caries and surface caries of permanent teeth (DMF = 6.79 ± 2.34, DMFS = 8.69 ± 2.75, р < 0.001) was established in children exposed to ionizing radiation and suffering DTF. Such a high intensity may be due to the impact of a set of negative factors including the ionizing radiation in low doses and peculiarities of economic component of social status of study subjects, namely the unbalanced diet. In case of permanent occlusion the intensity of caries and caries of tooth of in children survived after the ChNPP accident and suffering SEH was significantly (р < 0.05) higher compared to the persons suffering MIH. Key words: children, caries, disturbances in tooth formation, systemic enamel hypoplasia, molar-incisor hypomineralization, ionizing radiation, ChNPP accident.

Aim: To present the report of a female patient, 10 years old, referred for treatment in the Dentistry Clinic of a Brazilian public university.Case report: The patient's oral health condition was unfavorable with biofilm accumulation, pain report and chewing difficulty. After anamnesis, clinical and radiographic examination, the treatment plan included removal of infectious foci (54, 55, 64, 65, 74, 75, 85, 16, 36 and 46) followed by prosthetic rehabilitation. At this stage, the functional restoration of the lower arch was restricted by the imminent eruption of the premolars. In the upper arch, the maintenance of the mesio-distal diameters aims to guarantee the chronological sequence of successors irruption and establishment of normal occlusion. During the monthly follow-up consultations the patient presents a more spontaneous smile, although she still needs constant reinforcement in oral hygiene habits.Conclusions: The rehabilitation of patients with loss of permanent teeth during the mixed dentition phase should consider the peculiarities of this period for the restoration of health without altering the normal pattern of occlusal development.

Supernumerary teeth are defined as any supplementary tooth in addition to usual configuration of twenty deciduous and thirty-two permanent teeth. They are most commonly found in the anterior maxilla and mandibular bicuspid region. Although supernumerary teeth have been reported in the incisor region of the mandible, they are very rare. It has been confirmed that approximately 25% of permanent supernumerary teeth appear in the mouth, the rest remains unerupted. The aim of this study was to present a case of single, erupted, supernumerary tooth in the right incisal region of the mandible. A patient showed up at the dental office complaining about aesthetic problem caused by a supernumerary tooth in mandibular incisal region. On intraoral examination, a supernumerary tooth, conical in shape and labially positioned, between the tooth 42 and 43, was observed. On previously taken panoramic radiogram, six months ago, the supernumerary tooth was undetected. Because the supernumerary tooth was masked by the denser overlying cortical bone, it was difficult to interpret the radiogram correctly. It should be noted that panoramic radiography does not guarantee accurate diagnosis of supernumerary teeth, therefore additional diagnostic methods are required.

Tetracycline Derivative

Tetracycline may cause tooth discoloration when used in young children during tooth development. Whether tigecycline, a tetracycline derivative, has either a similar adverse event or not remains unclear. We assessed the discoloration of the permanent teeth of patients <8 years old after tigecycline exposure. These patients were identified through a retrospective chart review in a Chinese children’s hospital. Those who had at least one erupted permanent tooth after tigecycline exposure were interviewed, examined, and photographed by an experienced pediatric dentist and independently assessed by another senior dentist to detect tetracycline-like tooth discoloration. We identified 101 patients who were exposed to tigecycline, 12 of whom were included. The mean dose of tigecycline was 2.3 mg/kg/day (standard deviation, 0.6), and the median duration was 12.5 days (interquartile range [IQR], 8.0 to 19.3). The median age of exposure was 5.2 years (IQR, 4.5 to 7.4), and the median age of dental examination was 9.1 years (IQR, 9.0 to 10.3). Two patients (16.7%) developed yellow discoloration: a girl having yellow discoloration with white-to-yellow opacities in the upper lateral incisors and lower incisors, and a boy with a suspicious buccal yellow discoloration and enamel dysplasia in the second molars. The incidence and extent of tigecycline-associated dental adverse events remain unclear due to the small sample size and inadequate follow-up period.
