“…Our study shows that in patients with nasal septum deviation, the ipsilateral nasal bone length and bone thicknesses were greater than that on the contralateral side. It is thought that nasal septum deviation affects nasal bone development because this close relationship originates from embryologic stages of development [ 5 ]. Studies have suggested that there is a significant facial growth delay on the concave side of the deviated nose [ 17 ].…”

“…The nasal septum may affect nasal bone growth and facial morphology. From the initial growth stages, the maxillary bone and nasal structure have significant anatomic connections because of their close embryologic development [ 5 ]. In the growth period, the nasal septum acts as a growth plate that affects surrounding bones and facial skeletal tissues [ 6 ].…”

BackgroundNasal septal deviation may affect nasal bone growth and facial morphology. Knowledge of nasal morphologic parameters may plays an important role in planning successful rhinoplasty and septoplasty operation. The aim of our study was to evaluate the relationship between the direction and degree of nasal septal deviation with nasal bone morphology, along with factors such as age and gender.MethodsMaxillofacial computed tomography (CT) of 250 patients with nasal septal deviation was analyzed retrospectively in this study. We excluded patients with factors that could affect their nasal bone morphology, and a total of 203 patients (111 males, 92 females; mean age, 36.23 years; age range, 18–79 years) were evaluated. The nasal deviation angle was measured on coronal CT images as the angle between the most deviated point of the septum, and the midline nasal morphology was determined by measuring nasal length, internasal angle and lateral and intermediate nasal thickness on both sides.ResultsThe deviation of nasal septum has been detected as to the right in 107 patients (52.7%) and to the left in 96 patients (47.3%). Lateral and intermediate nasal bone thickness and nasal bone length were significantly greater on the ipsilateral deviation side (Table 3). No significant correlation was found between the variation of the nasal deviation angle and nasal bone morphology (Table 4). There were significant differences between the sexes for all investigated parameters except for the nasal deviation angle (p = 0.660). We found that the only internasal angle increases with aging (p = 0.002).ConclusionThe study shows that the direction of nasal septal deviation may be a factor that affects nasal bone morphology.

Objective This is a 6-month observational case-control study that aims to estimate plaque index (PI), salivary flow, buffering capacity of saliva, and specific Streptococcus mutans (S. mutans) and Lactobacillus rates in a mouth breathing late adolescents sample, after a professional oral hygiene procedure and home oral hygiene instructions. Subjects and Methods A sample of 20 mouth breathing late adolescents/young adults (average: 19.2 ± 2.5; range: 18–23 years) and a matched control group of nose breathing subjects (average: 18.3 ± 3.2; range 18–23 years) were included in the study. All the participants were subjected to a professional oral hygiene procedure and appropriate home oral hygiene instructions (t0). After three months (t1) and six months (t2), the PI, salivary flow, buffering capacity of saliva, and S. mutans and Lactobacilli rates were recorded. Results The mean buffering capacity of saliva and the salivary flow rate showed no significant difference between the two groups, all over the observational period. For PI, a significantly higher mode (score 1 of PI) was observed in the study group at t1 (score 0 = 35% of subjects; score 1 = 60%; score 2 = 5%) and t2 (score 1 = 65% of subjects, score 2 = 35%), with respect to control group. Furthermore, mouth breathing subjects show a significant 4 times higher risk to develop S. mutans CFU > 105 (CI lower limit: 0.95; CI upper limit: 9.48; chi-square: 4.28; p = 0.03), with respect to the control subjects. Conclusions Mouth breathing late adolescents show a significantly higher risk to develop S. mutans CFU > 105 and an increased level of PI. Interceptive orthodontic treatments in growing subjects, like palatal expansion, are encouraged to improve the nasal air flow. In older subjects, orthodontic treatments should be performed with removable appliances like clear aligners, in order to allow a better oral hygiene level.

“…Consequently, if in the upper arch it was therefore possible to increase the transverse diameters by separating the mid-palatine suture, this was not practicable in the lower arch. So, although rapid palatal expansion has shown to be able to induce significant changes also in the mandibular arch, through a change in the tongue position [18][19][20][21], which tends to improve its diameter-often compressed in the contracted maxilla-this is not always sufficient to resolve larger crowdings [22].…”

Aim: The treatment of patients with mixed dentition, with inferior moderate dental crowding (the so-called borderline cases, between extraction and expansion) is not yet clear. Two examples of widely used appliances for increasing lower dental arch dimensions are the Schwarz’s appliance and lip bumper. The aim of this prospective study was to compare dental crowding and arch dimensions from pre- to post-treatment with lip bumper versus Schwarz’s appliance. Subjects and Methods: Pre- and post-treatment orthodontic records of twenty subjects (10 males and 10 females) were analyzed in the present study. Inclusion criteria were: first/second molar class malocclusion; crowding of the mandibular arch, from mild to moderate (4–6 mm); mixed dentition; age ≤ 9 years at the beginning of the treatment; stage CS1 or CS2 of maturation of the cervical vertebrae analysis (CVM) at the beginning of the treatment. Ten subjects were treated with a lip bumper, and ten with the removable Schwarz appliance. The primary outcomes were the variations in dental crowding and arch dimensions from pre- to post-treatment. Results: Both the two appliances caused a statistically significant mean improvement/reduction in crowding, of 3.5 mm and 2.9 mm, for the Schwarz appliance and lip bumper, respectively. The Schwarz appliance resulted more effective in increasing arch dimension at the intercanine level, and arch perimeter, while the lip bumper achieves a higher increase in arch length. Conclusions: A lip bumper and Schwarz appliance are both useful in reducing crowding in mixed dentition. This improvement is due to the increase in dental arch dimensions, although the distribution of space resulted slightly differently between the two appliances.
