Association of dyslalias and dentomaxillary anomalies in children. Review of the literature.

It is common to find children with problems to communicate and this can be the product of a speech disorder, which corresponds to an alteration that involves the pronunciation or production of sounds. The most frequent speech disorder among school children is dislalias, with a prevalence of 70%. The malocclusions occupy the third place of prevalence within oral health problems, after dental caries and periodontal disease. Latin America has a worrying situation in this regard, with high levels of incidence and prevalence of malocclusions that exceed 85% of the population. The aim of this study is to review the existing association between dentomaxillary anomalies and dyslalias in children described in the literature for children and adolescents. In general terms, there are few studies that have evaluated this association. There is a positive association between the presence of dentomaxillary anomalies and the presence of dyslalias. Despite the above, there are few studies that have evaluated this association, so it is necessary to conduct more studies in this area.

Impact of social determinants on tooth loss. Bibliographic review

In Chile, dental caries is one of the most prevalent chronic oral diseases along with gingival, periodontal diseases and dentomaxillary anomalies. Chronic diseases represent the bulk of Chile’s health burden. These diseases are associated with habits that are usually acquired early in childhood or adolescence and that are also associated with a complex and multiple network of determinants. The social determinants of health are defined as the social conditions in which people live and they work, and they influence positively or negatively on health. Social determinants intervene markedly in oral health, where people with fewer resources and lower educational level have more pathologies and less access to treatments. The empirical evidence analyzed provides useful information to consider that the Social Determinants of Health have a great influence on the health of the individuals, however, there are few investigations that directly relate the loss of dental pieces with these determinants. The objective of this article is to review the association between tooth loss and the social determinants of health.

Oral morbidity and associated factors in Chilean preschoolers and schoolchildren: A preliminary review.

Currently, the most prevalent oral pathologies in Chile are dental caries, periodontal diseases, and dentomaxillary anomalies, with dental caries being considered the most prevalent in childhood and a public health problem. In Chile, research on and diagnosis of these diseases in preschoolers and schoolchildren are varied over time, but there is no review of the existing studies relating these pathologies to the most common risk factors, such as socioeconomic level, rurality, and nutritional status. The objective of this preliminary review is to assess oral morbidity in preschoolers and schoolchildren associated with risk factors in Chile. A national study found that the prevalence of caries is 16.8% at two years, 49.6% at four years, 70.4% at six years, 62.5% at 12 years, and 73.9% at 15 years. In relation to the severity of caries, it found a DMFT of 0.5 at two years, a DMFT of 2.3 at 4 years, and a DMFT of 3.7 at six years in temporary dentition. In permanent dentition, that the same study found a DMFT of 0.15 at six years, a DMFT of 1.9 at 12 years, and a DMFT of 3.0 at 15 years. Regarding gingivitis, it found a prevalence of 32.6% at two years, 45% at four years, 55.1% at six years, and 66.9% at 12 years. As for dentomaxillary anomalies, 33.3% presented some degree of anomaly at four years, 38.3% at six years, and 53% at 12 years. Despite the above, there are various studies in specific localities that have found a higher prevalence and severity of oral diseases. However, it is necessary to carry out a systematic evaluation to determine the prevalence and severity for each of the most prevalent oral diseases, as well as to identify the risk factors for the incidence of said diseases.

Incidența patologiei din zona oro-maxilofacială pe un lot de pacienți prezentați în serviciul de radiologie asociat spitalului „Prof. Dr. Dan Theodorescu“

Objective. The evaluation of the oral maxillo-facial health is an important topic in all countries, since the information is useful to the health districts, health insurance houses, academic scholars and clinicians. Our study represents a survey regarding the types of pathology in the population starting from the analysis of the cases in the department of radiology associated to „Prof. Dr. Dan Theodorescu“ Hospital in Bucharest. Materials and methods. Several physicians analyzed the X-rays and/or the computer tomograph scans for a group of patients who came to the department in a period of 6 months (June-December 2015). Results and conclusions. The results allowed us to divide the problems into 6 categories, based on: a) very high prevalence (over 150 out of 200 cases): caries and edentations; b) high prevalence (approx. 90/200 cases): parodontopathy and periapical complications; c) average prevalence (approx. 30/200 out of cases): bone fractures, cysts, sinusitis, dento-maxillary anomalies; d) low prevalence (approx. 10/200): dental fractures; e) very low prevalence (approx. 5/200): tumors, discharge, TMJ afflictions; f) lowest prevalence (approx. 2/200): Eagle syndrome, osteonecrosis, foreign bodies and sialoliths.

CORRELATION BETWEEN UPPER DENTITION AND SMILE PARAMETERS

Aim. The aim of the study was to estimate the influence of different anthropometric parameters of the upper dentition on esthetic parameters of the smile in patients with dentomaxillary anomalies accompanied by the narrowing of the upper dentition. Materials and methods. Forty eight patients underwent clinical examination with facial photometry and anthropometric study of plaster model of the upper jaw. Five parameters were taken into consideration: transverse size of the upper dentition in the regions of canines, first premolars and first molars, buccal corridors, visible dentition width. Results. All five parameters were compared with each other by means of scatter diagram. No correlation between the parameters was observed. Four clinical cases, confirming absence of correlation between the studied parameters, were described. Conclusions. There is no correlation between the narrowed upper dentition and the size of buccal corridors, visible while smiling. It is necessary to study these parameters in patients before, in the course of and after treatment.

Dento-maxillary anomalies among children with nasal septum deformations

Dento-maxillary anomalies among children with nasal septum deformations

Methods of septum surgery (septoplasty) with cresto- and suturotomy

High frequency of a combination of such symptoms as a curvature of a nose septum (NSC) dentomaxillary anomalies (DMA), high standing of the palatum, reduction of the horizontal and vertical sizes of a cavity of a nose are united and named as Khasanov rhinomaxillary (orthodontic rhinological ) symptom complex. The operative interventionseptum surgery with crestosuturotomy is prescribed to patients with Khasanov symptom complex . The musculomucosal graft is detached, a cartilage is separated from the bottom of a nasal cavity and moved in the opposite side. Thus the nasal crest of a palatal shoot of the top jaw becomes visible and it is removed with a gro oved chisel (crestotomy). Suturotomy is made to sutura palatina mediana of the bony palate which is from 2� to 5�mm deep and u p to 3�4� mm wide in the form of a trihedral trench. Our experience shows that, patients with Khasanov symptom complex after surgi cal correction of the nasal septum and osteotomy of the nasal crest of a palatal shoot of the top jaw, the orthodontic disclosing of a palatal stitch occurs several times faster, anomaly relapses of dentomaxillary systems decrease.

Clinical assessments on the dento-maxillary anomalies

Abstract The dento-maxillary anomalies, through their characteristics, ie widespread population mass, the impact that occurs at a personal level and in society and the etiological factors, have become a public health problem, ranking first in dental diseases, prior to dental caries and periodontitis. The prevalence of the dentomaxillary anomalies vary by study population, age group, geographical environment, socio-economic factors and the historical moment of the research. This clinical study was conducted over a period of five years, from 2006 to 2011, on a number of 320 study models, for diagnosis and treatment strategies. The study allowed the assessment of increasing trends of dentomaxillary anomalies, with a frequency of 44% in large cities, while in subjects with caries and periodontitis, the index is 41%. The large percentage differences reported between some authors are mainly due to patients, but also to different research methods, doctors training and errors of interpretation. The orthodontic treatment should answer to the expectations of the patient, thus to restore the morpho-functional integrity and the dentomaxillary functions, with minimal biological sacrifice.
