Congenitally Missing Maxillary Lateral Incisors: Functional and Periodontal Aspects in Patients Treated with Implants or Space Closure and Tooth Re-Contouring

To evaluate functional and periodontal aspects in patients with unilateral or bilateral congenitally missing maxillary lateral incisors, treated with either implants or space closure and tooth re-contouring. The sample consisted of 68 volunteers, divided into 3 groups: SCR - space closure and tooth re-contouring with composite resin (n = 26); SOI – implants placed in the area of agenesis (n = 20); and CG - control group (n = 22). A modified Helkimo questionnaire and the Research Diagnostic Criteria for Temporomandibular Disorders were used by a single, previously calibrated evaluator to assess signs and symptoms of temporomandibular joint disorder. The periodontal assessment involved the following aspects: plaque index, bleeding upon probing, pocket depth greater than 3 mm, gingival recession, abfraction, periodontal biotype and papilla index. The data were analyzed using Fisher's exact test and the nonparametric Mann-Whitney and Kruskal-Wallis tests (α=.05). No differences in periodontal status were found between treatments. None of the groups were associated with signs and symptoms of temporomandibular joint disorder. Both treatment alternatives for patients with congenitally missing maxillary lateral incisors were satisfactory and achieved functional and periodontal results similar to those of the control group.

OBJECTIVE: The aim of this study was to determine the prevalence and the relation between the main occlusal factors and the temporomandibular disorder (TMD). METHODS: We analyzed 100 patients (50 diagnosed with TMD and 50 asymptomatic volunteers, control group) through a questionnaire that classified TMD as absent, mild, moderate and severe. Then, an evaluation was made of intraoral occlusal factors: Absence of posterior teeth, wear facets, overjet, overbite, open bite, posterior crossbite, sagittal relationship (Class I, II and III), centric relation discrepancy for maximum intercuspation, anterior guidance and balancing occlusal interference. The c² examined the association between TMD and considered occlusal variables. RESULTS: The prevalence of studied occlusal factors was higher in patients with moderate and severe TMD. Statistically significant results were found on: Absence of five or more posterior teeth, overbite and overjet greater than 5 mm, edge-to-edge bite, posterior crossbite, Class II and III, the absence of effective anterior guide and balancing side interferences. CONCLUSIONS: Indeed, it is concluded that there is a relationship between TMD and occlusal factors, however it can not be told to what extent these factors are predisposing, precipitating or perpetuating the disease. Therefore, despite its multifactorial etiology, one can not neglect the occlusal analysis of these patients.

The present study aimed to evaluate the surface electromyography (sEMG) activity of the masseter muscles in patients with a history of temporomandibular joint disorder (TMJD) who received orthodontic treatment. In total, 22 participants aged 18–35 years old were included in this study. They were divided into the control group (patients without a history of TMJD [n = 11]) and the test group (those with a history of TMJD [n = 11]). Each participant underwent sEMG of the right and left masseter muscles at 5-s maximum voluntary contraction (MVC). Results showed that the TMJD group had a lower sEMG activity of masseter muscles at MVC than the non-TMJD group. However, the differences were not statistically significant (p > 0.05, t-test). The Spearman’s correlation coefficient test revealed a weak negative correlation between muscle activity on sEMG and history of TMJD (p > 0.05). In conclusion, orthodontically treated patients in TMJD group have reduced masseter muscle activity during MVC, compare to the non-TMJD group.

Background and Objectives: Awareness of temporomandibular joint disorder (TMD) is fairly concerning in management of physiotherapy as patients often seek for treatment from orthodontics when pain become their main concerns. In this case, cervical aspects are often overlooked in the treatment of temporomandibular joint disorder. This study aims to determine the effect of cervical extensor strengthening on severity of temporomandibular joint disorder. Methods: A randomized controlled trial study was carried out for 4 weeks to determine the effect of cervical extensor strengthening on severity of temporomandibular joint disorder among university students. A total of 40 participants were recruited via convenient sampling method. Subjects were randomly assigned into two groups: experimental group (E) and control group (C) through lottery randomization. Subjects in experimental group were instructed to perform 1 set of cervical extensor strengthening with 10 repetitions and goldfish exercises whereas subjects in control group were asked to perform goldfish exercises only. A pre-test and post-test severity of TMD, maximal mouth opening and maximal isometric cervical extensor strength were measured for both groups. Results: After 4 weeks of training, there was significant difference in pre-test and post-test severity of TMD and maximal mouth opening for both E and C group. On the other hand, there was significant difference of pre and post-test of maximal isometric cervical extensor strength in experimental group. There was no significant difference in post-test for severity of TMD (p=0.67), maximal mouth opening (p=0.21) and maximal isometric cervical extensor strength (p=0.40) between two groups. Conclusions: The study concluded that, 4 weeks of anti-gravity cervical extensor strengthening exercises protocol showed there was no significantly difference of the severity of TMD and maximal mouth opening between both control and experimental group. On the other hand, goldfish exercises showed significant improvement of maximal mouth opening and reduction in severity of TMD after 4 weeks of intervention period.

Objective To determine the prevalence, sociodemographic features, and clinical presentation of temporomandibular joint disorder in otorhinolaryngological practice. Methods This prospective hospital-based study involved patients diagnosed with temporomandibular joint disorder in our institution’s ear, nose, and throat department. Data for this study were obtained from the patients using pretested interviewer-assisted questionnaires. Results The prevalence of temporomandibular joint disorder in this study was 1.3%. The study population included 17 (26.2%) male patients with a male:female ratio of 1.0:2.8. Joint disorder accounted for 75.4% of all disorders, while both mastication muscle and joint disorder accounted for 21.5%. A majority of the patients (47.7%) presented between weeks 1 and 13 of the illness. Unilateral temporomandibular joint disorder accounted for 98.5% of all disorders. The main otologic clinical features were earache and a dull tympanic membrane in 100% and 35.4% of patients, respectively. Middle ear assessment revealed type A in 73.8% of patients and type B in 20.0% according to Jerger’s classification system of tympanometry. Most patients (81.5%) were referred by their family physician. All patients had undergone prehospital treatment prior to presentation. Conclusion Temporomandibular joint disorder is a common presentation in medical practice. Common clinical features include ear, joint, and mastication muscle disorders.
