    Comparative evaluation of salivary microbial levels and periodontal status of patients wearing fixed and removable orthodontic retainers
    (MOSBY-ELSEVIER, 2019) Eroglu, Ahmet Kubilay.; Baka, Zeliha Muge.; Arslan, Ugur.
    Introduction: The purpose of this study was to compare and evaluate salivary microbial levels and periodontal status in patients using a fixed lingual retainer, a removable vacuum-formed retainer, or a Hawley retainer after orthodontic treatment with fixed appliances. Forty-five patients who finished their orthodontic treatment with fixed appliances and were about to start the retention phase were randomly divided into the following 3 groups of 15 individuals each: the fixed lingual retainer group, the vacuum-formed retainer group, and the Hawley retainer group. Periodontal measurements, such as the plaque index, gingival index, probing depth, and bleeding on probing, were obtained at the following 4 time points: at debonding (T0) and 1 week (T1), 5 weeks (T2), and 13 weeks (T3) after debonding. Saliva samples were collected 3 times in total: at T0, T2, and T3. A quantitative analysis for Streptococcus mutans and Lactobacillus casei was performed with the use of real-time polymerase chain reaction. The Kruskal-Wallis test and 1-way analysis of variance were used for the statistical comparisons of the groups. No statistically significant difference in salivary S mutans and L casei levels was found among the 3 groups (P >0.05). They showed no statistically significant differences in plaque index, gingival index, bleeding on probing, and probing depth values (P >0.05). All periodontal parameters showed statistically significant decreases from T0 to T3 in all 3 groups (P <0.001). The S mutans and L casei levels were decreased significantly from T2 to T3 in the lingual retainer and Hawley retainer groups, whereas they decreased significantly from T0 to T3 in the vacuum-formed retainer group. Fixed and removable orthodontic retainers do not differ in salivary S mutans and L casei levels and periodontal status. With all retainers, regardless of whether they are fixed or removable, oral hygiene improved after orthodontic treatment with fixed appliances.

    Evaluation of the facial soft-tissue thickness in patients with cleft lip and palate
    (LIPPINCOTT WILLIAMS & WILKINS, 2019) Erdur, Emire Aybuke.; Baka, Zeliha Muge.; Fidanboy, Merve.; Erdur, Omer.
    Aim: In this study the authors aimed to evaluate craniofacial morphology and facial soft tissue thickness of the patients with cleft lip and palate.(CLP), and to compare the results with a sex and age-matched noncleft healthy control group. Methods: Craniofacial and soft tissue thickness measurements of 20 patients with unilateral cleft lip palate (UCLP) and 20 patients with bilateral cleft lip palate (BCLP) were compared with 20 noncleft control subjects. Angles between Sella-Nasion-A point, Sella-Nasion-B point, Nasion-A and Nasion-B line, Sella-Nasion line and Gonion-Gnation line, and linear (glabella, rhinion, subnasale, labrale superius, stomion, labrale inferius, labiomentale, pogonion, and gnathion) measurements were assessed on lateral cephalometric radiographs. Group differences were evaluated with 1-way analysis of variance and post hoc Tukey test. Results: Unilateral cleft lip palate and BCLP groups demonstrated lower values of skeletal measurements than control group except for Sella-Nasion line and Gonion-Gnation line value (P< 0.01). Maxillary incisors were retruded in BCLP group compared with the other groups (P< 0.001). Thickness of the rhinion, subnasale, and stomion demonstrated no significant difference between UCLP and BCLP groups (P> 0.05). Thickness of rhinion and stomion was found significantly higher in both groups, and thickness of the subnasale was found significantly lower than the healthy group (P< 0.05). Conclusion: Findings of the study suggested that patients with CLP showed differences on craniofacial morphology and facial soft tissue thickness. Before planning orthodontic treatment and esthetic surgeries, soft tissue thickness should be taken into consideration in addition to skeletal measurements in CLP patients.
