Prevalence of malocclusions, oral habits and orthodontic treatment need in a 7- to 15-year-old schoolchildren population in Tirana

Abstract

BackgroundThe aim of present study was to determine the prevalence of malocclusions, oral habits and the need for orthodontic treatment in a sample of 7- to 15-year-old Albanese schoolchildren.MethodsThe final sample comprised 2,617 subjects (1,257 males and 1,360 females), all orthodontically untreated. Occlusal relationship and the functional analysis were recorded for all subjects. The prevalence rates for the dental health component of the index of orthodontic treatment need (IOTN) were calculated. Comparisons between genders were performed for the prevalence of malocclusions, oral habits and IOTN grades (chi-square tests).ResultsClass I, class II and class III malocclusions and asymmetries were observed in 40.4%, 29.2%, 3.2% and 27.1% of the sample, respectively. There were 2,108 subjects (80.6%) that showed oral habits, with females (82.1%) presenting with a greater prevalence rate than males (78.9%). The objective need for orthodontic treatment (grades 4 and 5 of IOTN) was registered in 1,077 subjects (41.2%). This prevalence rate is higher than those reported for other European countries. No significant differences between genders were found for the IOTN grades.ConclusionsThe findings of the present study revealed the need to improve public health plans for orthodontic prevention and screening and to organise the resources in this area in Albania.

Prevalence of Need of Orthodontic Treatment in 7–16-Year-Old School Children in Udaipur City, India

“…This finding is supported by the reports of the earlier researches (19,23,27). Other studies of similar nature found no variation between the male and female children for the different IOTN grades, thereby opposing the view of gender bias (13,16,18,21,22,(24)(25)(26)28,30).…”

“…Nevertheless, there are other studies on different ethnic groups, which show a higher prevalence of the definitive need of treatment, ranging between 38% and 59% (14,17,18,22,25,26,28). In one of the studies on Pakistani children, the prevalence of definitive treatment need was 76% which was much higher than the findings of the current population (22).…”

“…Researches around the world have used IOTN to determine the need of malocclusion treatment in different population groups (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). DHC of IOTN is considered as an objective and synthetic method of verifying the malocclusion status and need of orthodontic treatment.…”

Relación entre las características periodontales y la sonrisa gingival en niños: un estudio de casos y controles

“…En México, en población aborigen, se encontró mayor porcentaje de maloclusión clase ii (46,33%), seguido de la clase iii (38,98%) y, por último, la clase i (13,56%) [26]. En población albanesa, también se encontró mayor prevalencia de clase i (40%) seguida de la clase ii, (29,8%) y la maloclusión menos presente fue la clase iii [27]. Así mismo, los estudios en diferentes poblaciones muestran diferentes patrones.…”

“…La literatura científica ha estudiado la relación que existe entre los hábitos bucales que son considerados no funcionales y la presencia de alteraciones en el sistema estomatognático [1][2][3][4]. Para el caso de la respiración bucal, esta se presenta por obstrucción (vías aéreas), por hábito o por anatomía, y es muy común en la población infantil.…”
