Effectiveness of Laser Therapy and Laser Acupuncture on Treating Paraesthesia After Extraction of Lower Third Molars.

This randomized clinical trial evaluated the sensitive return of the lower alveolar nerve (LAN) using two photobiomodulation therapy (PBMT) techniques, after the extraction of lower third molars or implant surgery. Sixty participants with sensory impairment of LAN were randomly divided into three groups ( = 20): group C-systemic medication (control-ETNA, 01 capsule, 8/8 h, 30 days); group laser therapy (LT) (808 nm, 100 mW, 40 sec/point, 4 J/point, intra/extraoral, irradiation following nerve path); group laser acupuncture (LA) (same parameters as the LT group, applied at six acupuncture points on the affected side (ST 4 [Dicang], M-HN-18 [Jiachengjiang], CV 24 [Chengjiang], ST 5 [Daying], ST 6 [Jiache], and point A1 [YNSA]). The following evaluations were performed, at predetermined times: general perception of paresthesia, thermal perception, vibratory mechanical perception, two-point discrimination, pain perception, and tactile perception.

Increased Anxiety-Like Behavior in the Acute Phase of a Preclinical Model of Periodontal Disease.

Periodontal disease (PD) is an infectious-inflammatory oral disease that is highly prevalent among adolescence and adulthood and can lead to chronic orofacial pain and be associated with anxiety, stress and depression. This study aimed to identify anxiety-like behaviors in the ligature-induced murine preclinical model of PD in different phases of the disease (i.e.

Chronic facial pain: different comorbidities and characteristics between neuropathic and nonneuropathic conditions.

Objective: The aim of this study was to investigate the association between comorbidities and chronic diseases and neuropathic and nonneuropathic orofacial pain diagnoses to suggest subclassifications of disease.

Study Design: This was a cross-sectional, retrospective, case-control study. We evaluated 174 patients with orofacial pain and 132 controls by using a systematic protocol that consisted of medical history and demographic, pain, and orofacial characteristics.

Pain and temporomandibular disorders in patients with eating disorders.

Orofacial pain and temporomandibular dysfunction may cause chronic facial pain, which may interfere with the emotional state and food intake of patients with eating disorders (ED), such as anorexia nervosa (AN) and bulimia nervosa (BN). Sixty-four patients were assigned to four groups: Group A (AN - restricting subtype): 07; Group B (AN - purging subtype ): 19; Group C (BN): 16; and Group D (control): 22. Complaints of pain are more prevalent in individuals with eating disorders (p<0.

Existential Meaning of Patients with Chronic Facial Pain.

Coping strategies are necessary to deal with pain, one of the most disabling conditions. Treatments are often refractory, and the elaboration of existential meaning is necessary to live with residual pain. The objective of this study was to discuss the relevance of the meaning of life in coping with refractory chronic neuropathic facial pain according to singular cases.

Post-operative orofacial pain, temporomandibular dysfunction and trigeminal sensitivity after recent pterional craniotomy: preliminary study.

Background: Surgical trauma at the temporalis muscle is a potential cause of post-craniotomy headache and temporomandibular disorders (TMD). The aim of this study was to evaluate the prevalence of pain, masticatory dysfunction and trigeminal somatosensory abnormalities in patients who acquired aneurysms following pterional craniotomy.

Methods: Fifteen patients were evaluated before and after the surgical procedure by a trained dentist.

Effects of localized versus widespread TMD pain on sleep parameters in patients with bruxism: A single-night polysomnographic study.

Objective: The purpose of this study was to investigate whether the presence of concomitant widespread pain could influence the polysomnographic characteristics of patients with Sleep Bruxism(SB) and chronic masticatory muscle pain(TMD).

Methods: 20 SB/TMD patients (17 women and 3 men) were evaluated according to the RDC/TMD questionnaire; and were divided into two groups according to the absence (Group A) or presence (Group B) of widespread pain. They were evaluated in a one night polysomnography paradigm.

Influence of Sexual Hormones on Neural Orofacial Perception.

Objective: To investigate the trigeminal somatosensory (thermal, pain, tactile, vibratory, and electric), gustative (salty, bitter, sweet, sour), and olfactory thresholds in healthy women during the menstrual cycle and investigate any association with estradiol and progesterone levels in saliva.

Methods: We examined/tested 39 women between age 19 and 47 years and with regular menstrual cycles and no comorbidities. All women were informed about the purposes of the study, and only those who signed the informed consent were included.

Quantitative sensory testing in fibromyalgia and hemisensory syndrome: comparison with controls.

Fibromyalgia syndrome (FS) is a chronic painful condition with sensory, motor and affective dysfunctions. Few studies had investigated the trigeminal area, and little is known about its association with hemisensory syndrome, which is characterized by chronic pain restricted to hemibody. Our objective was to investigate sensorial abnormalities with quantitative sensory testing of patients with FS and patients with hemisensory syndrome, compared to controls.

Facial sensibility of patients with trigeminal neuralgias.

Objectives: Idiopathic trigeminal neuralgia (ITN) is an excruciating shock-like paroxysmal pain restricted to the trigeminal area of innervation, with discrete loss of sensibility (thermal, tactile and painful). Trigeminal postherpetic neuralgia (PHN) is a neuropathic pain at the trigeminal territory that persists after Herpes zoster infection, which also is associated to sensorial compromise. The objective of this study was to evaluate the somesthetic facial sensibility (pain, thermal and tactile) and to compare the findings between PHN and ITN.

Temporomandibular Disorder in Brazilian patients: a preliminary study.

The objective of the current study was to evaluate disease-related beliefs, adherence to treatment, quality of life, coping strategies and cognitive status in a group of Brazilian patients with Temporomandibular Disorder (TMD). Thirty patients were evaluated with a semi-directed interview, the Coping Strategies Inventory, and a Mini-Mental State Examination. Although half (50%) of the patients had known their diagnosis long term, 40% of the sample were not correctly following proposed treatment.

Evaluation of the sensation in patients with trigeminal post-herpetic neuralgia.

Background: Post-herpetic neuralgia (PHN) is one complication after herpes zoster infection, which may affect the facial superficial sensitivity.

Methods: Eighteen patients with PHN were interviewed and evaluated according to a systematized sensitivity approach, including mechanical, thermal and pain.
